TYPICAL SPECIFICATION OF AUTOMATED CONTROL UNIT

CENTRAL HEATING SYSTEMS FOR RESIDENTIAL BUILDINGS

The share of heating costs is predominant in utility bills throughout our country. At the same time, in northern regions, and also where imported fuel oil is used as fuel, thermal energy is especially expensive. For this reason, the issue of economical consumption and reasonable use of thermal energy is one of the most urgent today.
As you know, savings start with accounting. Today, meters of thermal energy supplied to an apartment building are installed almost everywhere. Statistics show that this simple measure has reduced heating costs by 20% and sometimes even 30%. But this is not enough, we need to move on and the vector of this movement should be directed towards apartment-by-apartment heat metering and reducing energy consumption, depending on the reduction in demand for it.
To do this, it will be necessary to reconstruct the elevator input and install a control unit for the heat supply system with automatic regulation of its operation depending on the outdoor temperature. It is also necessary to install pumps with frequency regulation of their operation. Most efficient system will be when installing a temperature control sensor and a meter for accounting for the consumption of thermal energy on each heating radiator.
Of course, this will require cash, which, by preliminary calculations, should pay off within two years of operation of the system. You can use the funds from the federal program to improve the efficiency of the use of energy resources, take a loan and repay it at the expense of monthly receipts from residents, highlighting separately the expense column for the reconstruction of the heating system. You can simply "chip" and thereby stop throwing your own money into environment together with irrationally used thermal energy.
The main thing is to understand that the heating system that exists today, especially during the off-season, is like a fire lit on the balcony: it warms, but not what you need.

Perfect option
The ideal option The heating system for the consumer is a heating network that automatically maintains the set temperature in each room. At the same time, for residents, the motivation for its installation and use should be not only comfortable conditions living (you can simply regulate the temperature by opening a balcony door or a window to the street), but also a reduction in heating costs.
For this you need apartment system metering of thermal energy consumption. Sales companies insist that in our country, with its traditional vertical distribution of the heating system, it is impossible to install a heat meter for each apartment, but at the same time it is overlooked (or simply there is no desire to see and take it into account) that heat meters can be installed on each heating radiator, while not changing the two-pipe or one-pipe vertical heat distribution to a horizontal one.
When calculating for heat, it is enough to sum up the readings of all meters. Even an elementary school student can handle it.
Individual metering of thermal energy will allow you to consciously save heat by stopping its supply to those rooms where no one lives temporarily or simply preferring to be in a cool room. To do this, you can close the taps installed on each radiator.
But there is another way to regulate heat consumption: the use of a radiator thermostat, consisting of a valve and a thermostatic head. The principle of operation of the system is simple: the movement of the valve embedded in the pipe is controlled by a thermostatic head that reacts to changes in the temperature in the room: it is hot, the valve closes the pipe, it is cold, on the contrary, it opens. At the same time, using manual control, you can set the device as you wish: like it to be hot, set the maximum temperature on the controller that you want to get in the room.
There are thermostats with which you can adjust the temperature in the room depending on the time of day: no one is at home during the day, you can turn off the heating, turn it on in the evening.
It would seem that everything is simple: meters can be installed in each apartment, the amount of heat energy can be increased or decreased, and heating fees can be saved. But at the same time, the system for regulating the distribution of thermal energy throughout the house, that is, the traditional elevator input, is overlooked.

The principle of operation of the hydraulic elevator
The coolant is supplied to the hydraulic elevator from the main pipeline. Its pressure is regulated using a conventional valve. At the same time, the temperature of the network water is so high that it cannot be supplied directly to consumers, so the network water in the hydraulic elevator is mixed with the already cooled return flow.
If the coolant makes a cycle of movement through the heating system and at the same time does not consume the supply of thermal energy, which will certainly happen when the heating devices are turned off, the elevator will receive hot water from the network and hot water from the return pipeline.
The hydraulic elevator does not have feedback from the main pipeline and cannot reduce the pressure of network water. As a result, too hot water will be sent to consumers whose heating devices are not blocked and operate at full capacity, which will lead to damage to the equipment.
At the same time, the heat energy meter will not record a decrease in heat consumption, and the sales company will note overheating and impose penalties. It turns out that all efforts to reduce heating costs were made in vain.

What to do
We need a heating point with an automatic system for regulating the supply of network water

1. Hydraulic elevator
2. Electric drive
3. Control system
4. Temperature sensor
5. Temperature sensor of the heating medium in the supply pipeline
6. Return temperature sensor

It uses a heat exchanger in which network water and water from the main pipeline are mixed. AT heating system this "mixture" is served. Its temperature is also measured when allowable value the supply of main water is blocked, which leads to a decrease in the consumption of thermal energy.
As a result, the consumption of thermal energy can be controlled.

Description:

Such measures are the installation of automated control units for heating systems (hereinafter referred to as ACU) instead of thermal or elevator units, the installation of balancing valves on the risers of heating systems and thermostatic valves on the connections to heating devices.

Errors in the implementation of automated control units for heating systems in Moscow (2008–2009)

A. M. Filippov, Head of the Energy Saving Control Inspectorate of the State Housing Inspectorate of Moscow

With the adoption of Federal Law No. 261-FZ dated November 23, 2009 “On Energy Saving and Improving Energy Efficiency and on Amending Certain legislative acts of the Russian Federation” the importance of energy saving in residential buildings is growing, especially measures that allow not only automating, but also reducing the consumption of thermal energy by apartment buildings, as well as optimizing the distribution of heat between consumers in the house. Such measures are the installation of automated control units for heating systems (hereinafter referred to as ACU) instead of thermal or elevator units, the installation of balancing valves on the risers of heating systems and thermostatic valves on the connections to heating devices.

Prerequisites for the introduction of ACU

For the first time, the concept of AUU appeared back in 1995, when MNIITEP developed and approved the concept of "Modern Energy-Saving Heat Supply and Heating Systems for Buildings in the Mass Construction of Moscow" and a program for its implementation. Subsequently, the introduction of AMU was spelled out in the new edition of MGSN 2.01–99 “Energy Saving in a Building”, then on April 27, 2002, a meeting of the Complex of Architecture of the City of Moscow was held, at which, among others, they considered the issue “On standard technical solutions for equipping residential buildings under construction with automated control units of heating systems.

In 2008, MoszhilNIIproekt, together with Danfoss LLC, compiled an album “Automated control units” using technical solutions of a standard project, and in May 2008, the heat supply organization MOEK OJSC held two meetings with the participation of design and installation contractors AMU on the design and development of technical conditions for linking a typical project for the installation of an AMU during the overhaul of residential buildings of the 2008–2014 program.

Since August 2008, the mass introduction (installation) of ACU in residential buildings began instead of elevator and heating units, and at present in Moscow the number of residential buildings with installed ACU reaches 1000 buildings, which is approximately 3% of residential buildings in the city.

The principle of operation and the benefits of using ACU

What is the ACU, the device and the principle of its operation were described repeatedly in the works of M. M. Grudzinsky, S. I. Prizhizhetsky and V. L. Granovsky, including in. In addition, a similar principle of operation of the equipment is used in the central heating station of OAO MIPC (previously - in the heat points of the State Unitary Enterprise Mosgorteplo) in the system automatic regulation dependent heating system (SARZSO), but only for transitional modes in autumn and spring.

In short, ACU is a set of devices and equipment that provides automatic control of the temperature and flow of the coolant at the inlet to each building exactly in accordance with the temperature schedule specified for this building or in accordance with the needs of residents.

The advantage of ACU in comparison with thermal and elevator units that have a fixed cross section of the passage opening (elevator nozzle, throttle diaphragm), through which the coolant enters the house heating system, is the ability to change the amount of coolant supplied depending on the water temperature in the supply and return pipelines of the system heating with outdoor temperature correction in accordance with the temperature curve.

Unlike the elevator units installed on each section of the house, the ACU is usually mounted one per building (if there are 2 thermal inputs in the house, then 2 ACUs are installed), while the connection is made after the metering unit for the thermal energy of the heating system (if any ).

Schematic diagram and view of ACU in axonometry is shown in fig. 1, 2 (based on the materials of Danfoss LLC). Possible design options, due to the scheme of connection to the heating network, hydraulic modes at the thermal input, specific design building heating systems and operating conditions (12 standard solutions in total).

An exemplary scheme of the ACU provides: 1 - electronic unit (control panel); 2 – outdoor air temperature sensor; 3 – coolant temperature sensors in the supply and return pipelines; 4 – flow regulator valve with gear drive; 5 – differential pressure regulator valve; 6 - filter; 7 - circulation pump; eight - check valve.

As can be seen from the diagram, ACU basically consists of three parts: network, circulation and electronic.

The network part of the ACU includes a coolant flow regulator valve with a gear drive, a differential pressure regulator valve with a spring regulating element and a filter.

The circulation part of the ACU includes a circulation (mixing) pump and a check valve. As mixing pumps, two Grundfos pumps (or other types of pumps that meet the requirements of the ACU) are installed, which operate alternately on a timer with a cycle of 6 hours. The pumps are controlled by a signal from a differential pressure sensor installed on the pumps.

The electronic part of the ACU includes an electronic unit (control panel) that provides automatic control of the thermal and mechanical pumping equipment in order to maintain the given temperature chart and hydraulic mode in the heating system of the building, an ECL card (designed for programming the thermal mode controller), an outdoor temperature sensor (installed on the north side of the building facade), coolant temperature sensors in the supply and return pipelines and a geared electric drive for the coolant flow control valve in the network part Ayy.

Mistakes in the implementation of ACU

The main topic of this article is the mistakes made during the planning of work, design and installation of ACU in Moscow, which nullified all the work done and did not allow to obtain the planned indicators for energy efficiency and energy saving. For a year and a half, the installed AHUs were practically not used for their intended purpose or were used inefficiently, expensive equipment often stood idle in a disconnected state, and the coolant entered the house heating systems through undismantled elevators.

Of course, many of the mistakes were later corrected, and the work of the AMU was adjusted, but mistakes could have been avoided if the work was properly organized at all stages of the process.

So what were those mistakes?

1. At the stage of planning and organization of work.

When choosing technical solution, in violation of the requirements of MGSN 2.01–99 “Energy Saving in Buildings” (clause 4.2.1.), no technical and economic comparison of options was carried out: 1) installation of automatic control units from distribution networks of central heating stations or 2) installation of ITP from city main heat pipelines and water supply networks. As a result, when installing the ACU, the functions of the equipment installed in the central heating station were duplicated, which contradicts the "Rules for the technical operation of thermal power plants" of Rostekhnadzor of the Russian Federation (clause 9.1.2.), And the installation of the ACU and balancing valves led to an increase in hydraulic resistance in the system and the need to replace (reconstruction) of thermal and mechanical equipment of the central heating station. However, the reconstruction of the central heating substation was not envisaged, and the ACU was introduced not by the cluster method, starting from the end houses, but in an uncomplex way, only in individual buildings at the beginning or in the middle of the connection to the central heating substation. As a result, the non-complex installation of the ACU violated the established hydraulic and thermal balance in the intra-quarter heating networks, led to a deterioration in the operation of the heating systems of most of the attached buildings and necessitated expensive thermal adjustment (with the calculation of the diameters of the elevator nozzles and throttle diaphragms, their installation on the input distribution nodes and subsequent adjustment (replacement) during operation in heating period.

2. At the design stage:

- there were no working projects, often instead of working projects, copies from a standard project were used without calculations, selection and binding of equipment to local conditions, which led to erroneous decisions when choosing and installing equipment and, as a result, to violations of heat supply regimes during its operation;

- the selected installation schemes for the ACU did not meet the requirements, which immediately had a negative impact on the heat supply. For example, in three residential buildings of ZAO, as a result of dismantling elevator node and application of the ACU scheme in a dependent heating system, intended for independent systems without a mixing unit, the design temperature schedule of the system operation was violated (95–70 °С) and the primary superheated coolant with a temperature schedule (150/70 °С) entered the heating devices, which led to overheating of the residential premises closest along the coolant and to a violation of the circulation of the coolant in the end risers (underheating of the premises located on the end risers). Operation of the system in this mode was fraught with burns of residents when touching devices and pipelines. Only timely intervention helped eliminate this error before the onset of cold weather;

- the issued technical specifications (TS) did not correspond to the actual parameters: for example, the TS and the project indicated a schedule of 150/70 °С instead of the actual 105/70 °С, which led to the wrong choice of the ACU scheme. Also, when issuing technical conditions for the ACU, it was not taken into account that in the course of overhaul heating systems were reconstructed (schemes were changed from one-pipe to two-pipe, the diameters of the distribution pipelines and risers, the heating areas of heating devices, etc.), while the calculation of the AC was made for the heating system before the reconstruction.

3. At the stage of installation and commissioning:

- the time for installation was mistakenly chosen: ACUs were often mounted already in winter period after the completion of other works, which led to complaints from residents about the untimely start of heat, frequent shutdowns of heating, violations temperature regime;

– in vain they refused to install ACU in cases when balancing valves were installed on the risers of central heating systems during the overhaul. Their installation led to a sharp increase in hydraulic resistance in the systems, and in the absence of ACU with pumping equipment and no work was done to replace pumps in the central heating substation in such residential buildings and neighboring houses in the heating period, problems with heat supply immediately arose;

– outdoor air temperature sensors were not mounted on the north side of the building, which led to incorrect setting of the thermal regime due to the influence solar radiation on the sensor (its heating);

- the work of the ACU was carried out in a freelance manual mode and was not transferred to automatic mode;

– documents and ECL cards were missing due to the fact that the installer did not transfer them management company;

– there was no backup power supply for the AC, which in the event of a power outage could lead to a shutdown of the central heating system;

- adjustment and adjustment work and noise reduction measures were not carried out;

- there was no maintenance of the ACU.

As a result of these errors and violations, in houses with installed ACs, there were numerous complaints from residents about the non-heating of the heating system and the noise from the operation of the equipment.

All of the above became possible due to the poor organization of work, the lack of proper control by the customer over all stages of the process of introducing ACU. The author hopes that the published article will help to avoid such mistakes in the future both in Moscow and in other cities.

When introducing ACU, it is necessary to clearly organize the work of design organizations, relevant construction and installation and repair and maintenance services, carefully check the issued technical specifications for compliance with actual data, conduct technical supervision at each stage of work, and immediately after installation, begin maintenance of the ACU by a specialized organization. . Otherwise, downtime of the expensive ACU equipment or its unskilled maintenance will lead to failure, loss of technical documentation and other negative consequences.

Effective use of ACU

The use of ACU is most effective in the following cases:

- in houses with subscribed elevator nodes of the heating system, directly connected to the city's main heating networks;

– in end houses linked to the central heating substation with insufficient pressure drop in the central heating system with obligatory installation central heating pumps;

– in houses with gas water heaters (with decentralized hot water supply) and central heating.

ACU should be installed in a complex, cluster method, covering all, without exception, residential and non-residential buildings connected to the central heating substation.

Installation and commissioning of the heating system and ACU equipment must be carried out simultaneously.

It should be noted that along with the installation of ACU, the following measures are quite effective:

- transfer of the central heating substation with a dependent scheme for connecting heating systems to an independent one with the installation of a membrane expansion tank;

- installation in the central heating station with a dependent connection scheme of equipment for automatic control of heat supply (SAR ZSO), similar to AUU;

- adjustment of intra-quarter central heating networks with the installation of design nozzles for elevators and throttle diaphragms at the input distribution units of buildings;

– transfer of dead-end hot water supply systems to circulation schemes.

In general, the operation of exemplary ACUs has shown that the use of ACUs in conjunction with balancing valves on the risers of the central heating system, thermostatic valves on each heater and holding warming measures allows you to save up to 25-37% of thermal energy and provide comfortable living conditions in every room.

We will help you understand the concepts associated with the control units of heating and hot water systems, as well as the conditions and methods for using these units. After all, the inaccuracy of terminology can lead to confusion in determining, for example, the permitted type of work during the overhaul of MKD.

The equipment of the control unit reduces the consumption of thermal energy to the standard level when it enters the MKD in an increased volume. The uniform terminology should correctly reflect the functional load that such equipment carries. So far, there is no desired unity. And misunderstandings arise, for example, when the replacement of an outdated assembly with a modern automated one is called the modernization of the assembly. In this case, the outdated node is not improved, that is, it is not upgraded, but simply replaced with a new one. Replacement and modernization is independent species works.

Let's figure out what it is - automated control unit.

What are the control units for heating and water supply systems

The control nodes of any type of energy or resource include equipment that directs this energy (or resource) to consumers and regulates its parameters if necessary. Even a collector in the house, which receives a coolant with the parameters necessary for the heating system and directs it to various branches of this system, can be attributed to the thermal energy management unit.

Elevator units and automated control units can be installed in MKDs connected to a heating network with high coolant parameters (water superheated up to 150 °C). DHW parameters can also be adjusted.

In the elevator unit, the coolant parameters (temperature and pressure) are reduced to the specified values, that is, one of the main control functions is carried out - regulation.

In the automated control unit, automatic feedback control regulates the parameters of the heat carrier, providing the desired air temperature in the room, regardless of outdoor temperature air, and maintains the necessary pressure difference in the supply and return pipelines.

Automated control units for the heating system (AUU CO) can be of two types.

In ACU CO of the first type, the temperature of the coolant is brought to the specified values ​​by mixing water from the supply and return pipelines using network pumps, without installing an elevator. The process is carried out automatically using feedback from a temperature sensor installed in the room. The coolant pressure is also automatically regulated.

Manufacturers give this type of automated units a variety of names: heat control unit, weather control unit, weather control unit, mixing unit weather control, automated mixing unit, etc.

subtlety

Adjustment must be complete.

Some enterprises produce automated units that regulate only the temperature of the coolant. Lack of a pressure regulator can cause an accident.

AUU CO of the second type incorporates plate heat exchangers and forms an independent heating system. Manufacturers often call them heat points. This is not true and causes confusion when placing orders.

In DHW systems of MKD, liquid thermostats (TRZh) can be installed, which regulate the temperature of the water, automated control units DHW system, providing water supply of a given temperature according to an independent scheme.

As you can see, not only automated nodes can be attributed to control nodes. And the opinion that outdated elevator units and TRZh are incompatible with this concept is wrong.

The formation of an erroneous opinion was influenced by the wording in Part 2 of Art. 166 ZhK RF: “nodes for controlling and regulating the consumption of thermal energy, hot and cold water, gas". It cannot be called correct. Firstly, regulation is one of the functions of management, and this word should not have been used in the given context. Secondly, the word “consumption” can also be considered redundant: all the energy entering the node is consumed and measured by devices. At the same time, there is no information about the purpose to which the control unit directs thermal energy. It can be said more specifically: the control unit for thermal energy consumed for heating (or for hot water supply).

By managing thermal energy, we ultimately manage heating or hot water systems. Therefore, we will use the terms "heating system control unit" and "DHW system control unit".

Automated nodes are new generation control nodes. They answer the most modern requirements imposed on the subject of control of heating and hot water systems, and allow raising the technological level of these systems to the full automation of the processes of regulating the parameters of the temperature regime of air in rooms and water in hot water supply, as well as automation of heat consumption metering.

Elevator nodes and TRZH, due to their design, cannot meet the above requirements. Therefore, we refer them to the control nodes of the previous (old) generation.

So, let's sum up the first results. There are four types of control units for heating and hot water systems. When choosing a control node, find out what type it is.

Can the names be trusted?

Manufacturers of control units based on mixing supply and return pipelines often refer to their products as weather regulators. This name absolutely does not reflect their properties and purpose.

The automated control unit does not regulate the weather. Depending on the outside temperature, it regulates the temperature of the coolant. In this way, the set air temperature is maintained in the room. But the same is done by automated units with heat exchangers and even elevator units (but with less accuracy).

Therefore, we will clarify the name: an automated unit (mixing type) for controlling the heating system. Then you can add its name assigned by the manufacturer.

Manufacturers of automated control units with heat exchangers usually refer to their products as heat substations (TPs). Let's turn to the regulations.

To verify the incorrect identification of automated nodes with TP, let's turn to SNiP 41-02-2003 and their updated version - SP 124.13330.2012.

SNiP 41-02-2003 " Heating network» consider a heating point as a separate room that meets special requirements, which houses a set of equipment for connecting consumers of thermal energy to the heating network and giving this energy the specified parameters for temperature and pressure.

In SP 124.13330.2012, a heating point is defined as a facility with a set of equipment that allows changing the thermal and hydraulic regime of the heat carrier, accounting for and regulating the consumption of thermal energy and heat carrier. This is a good definition of TP, to which the function of connecting equipment to the heating network should be added.

In the Rules for the technical operation of thermal power plants (hereinafter referred to as the Rules), TP is a complex of devices located in a separate room that provides connection to a heating network, control of heat distribution modes and regulation of coolant parameters.

In all cases, the TP links together the complex of equipment and the room in which it is located.

SNiP subdivide heat points to stand-alone, attached to buildings and built into buildings. In MKD, TPs are usually built-in.

The heat point can be group and individual - serve one building or part of the building.

Now we formulate a correct definition.

An individual heating point (ITP) is a room in which a set of equipment is installed for connecting to a heating network and supplying consumers with an MKD or one of its parts of a coolant with regulation of its thermal and hydraulic regime to give the parameters of the coolant a given value for temperature and pressure.

In this definition of ITP, the main importance is given to the room in which the equipment is located. This is done, firstly, because such a definition is more consistent with the definition presented in SNiP and SP. Secondly, it warns about the incorrectness of using the concepts of ITP, TP and the like to refer to products manufactured on various enterprises automated control units for heating and hot water systems.

Let us also specify the name of the control unit of the type in question: an automated unit (with heat exchangers) for controlling the heating system. Manufacturers may indicate their own product name.

How to qualify work with the control node

Certain works are associated with the use of automated control nodes:

• installation of the control unit;
• repair of the control unit;
• replacement of the control unit with a similar one;
• modernization of the control unit;
• replacement of an outdated design unit with a new generation unit.

Let us clarify what meaning is invested in each of the listed works.

Installation of a control unit implies its absence and the need to install it in an MKD. Such a situation may arise, for example, when two or more houses are connected to one elevator unit (houses on a coupler) and it is necessary to install an elevator unit on each house in order to be able to separately account for the consumption of heat energy and increase responsibility for the operation of the entire heating system in each house. You can install any control node.

Control unit repair engineering systems ensures the elimination of physical wear and tear with the possibility of partial elimination of obsolescence.

Replacing a node with a similar one that does not have physical wear implies the same result as when repairing the node, and can be done instead of repair.

Modernization of the node means its renewal, improvement with the complete elimination of physical and partially obsolescence within the existing structure of the node. Both the direct improvement of an existing node, and its replacement with an improved node - these are all types of modernization. An example is the replacement of an elevator assembly with a similar assembly with an adjustable elevator nozzle.

Replacement of outdated design units with new generation units involves the installation of automated control units for heating and hot water systems instead of elevator units and TRZH. In this case, physical and moral deterioration is completely eliminated.

All of these are independent activities. This conclusion is confirmed by Part 2 of Art. 166 LCD RF, where as an example independent work the installation of the thermal energy control unit is given.

Why you need to define the type of work

Why is it so important to attribute this or that work related to control nodes to a certain type of independent work? This is of fundamental importance when performing a selective overhaul. Such repairs are carried out from the funds of the capital repairs fund, formed from the mandatory contributions of the owners of the premises to the MKD.

The list of works on selective overhaul is given in Part 1 of Art. 166 ZhK RF. The above independent works are not included in it. However, in Part 2 of Art. 166 of the Housing Code of the Russian Federation it is said that the subject of the Russian Federation can supplement this list with other works by the relevant law. At the same time, it becomes fundamentally important that the wording of the work included in the list corresponds to the nature of the planned use of the control unit. Simply put, if the node was to be upgraded, then the list should include work with exactly the same name.

Example

St. Petersburg has expanded the list of overhaul works

The law of St. Petersburg dated December 11, 2013 No. 690-120 “On the overhaul of common property in apartment buildings Petersburg" in 2016, the following independent work was included in the list of selective overhaul works: installation of control units and regulation of heat energy, hot and cold water, electrical energy, gas.

The wording is completely borrowed from the Housing Code of the Russian Federation with all the inaccuracies noted by us earlier. At the same time, it clearly indicates the possibility of installing a control and regulation unit for thermal energy, i.e. a control unit for the heating system and the hot water supply system, during selective overhauls carried out in accordance with this law.

The need to perform such independent work is due to the desire to disconnect the houses on the hitch, i.e. houses, the heating systems of which receive the coolant from one elevator unit, and install their own heating system control unit on each house.

The amendment made to the law of St. Petersburg allows you to install both a simple elevator unit and any automated control unit for engineering systems. But it does not allow, for example, to replace the elevator unit with an automated control unit at the expense of the overhaul fund.

Important!

Automated mixing units, which do not include a pressure regulator, are not recommended for use in high-temperature heat supply networks. Automated control units for the DHW system should only be installed with heat exchangers that form closed system DHW.

findings

1. The control nodes include all nodes that direct the energy carrier to the heating or hot water system with the regulation of its parameters, from outdated elevators and TRZh to modern automated nodes.
2. Considering the proposals of manufacturers and suppliers of automated control units, it is necessary to beautiful names weather regulators and heating points to recognize which of the following types of units the proposed product belongs to:

• automated mixing unit for heating system control;
• an automated unit with heat exchangers for controlling a heating system or a hot water supply system.

After determining the type of automated node, its purpose should be studied in detail, specifications, product cost and installation work, operating conditions, the frequency of repair and replacement of equipment, the amount of operating costs and other factors.

1. When deciding on the use of an automated control unit for engineering systems during a selective overhaul of an MKD, it is necessary to make sure that the selected type of independent work on the installation, repair, modernization or replacement of the control unit exactly corresponds to the name of the work included by the law of the constituent entity of the Russian Federation in the list of work on capital MKD repair. Otherwise, the selected type of work on the use of the control unit will not be paid at the expense of the capital repair fund.

A modern heating control system allows you to implement the most complex and advanced schemes and programs for adjusting equipment operation modes, achieve significant energy savings, provide remote control heating. We want to consider the heating control unit in terms of its design and operational features and advantages.

Automatic control unit

Purpose

The automatic control unit is an individual heating point designed to control the parameters of the coolant circulating in the heating system, depending on the temperature indicators in the room, on the street, in the supply and return pipelines of the circuit.

In addition, the system allows you to implement protection against emergency situations, switching equipment operation modes, GSM heating control. In the event of a breakdown or an emergency situation, the module is able to notify all subscribers included in the mailing list using SMS messages.

However, this is far from full list functions.

The control node can provide:

• Modes and parameters of operation, a given coolant circulation rate;
• Control of maintaining and fulfilling the specified temperature schedule of the supply and return pipelines. This allows you to protect the system from overheating and hypothermia;
• Maintaining a given constant pressure drop at the supply and return inputs to the building, which allows normal operation of all automation in normal mode;
• Fine and coarse cleaning of the coolant;
• Visual control of all performance indicators of the system: temperatures in key areas, pressure difference at the inlet and outlet of the unit, set operating mode, alarms;
• Remote control of heating by phone and via the Internet;
• Remote control of the premises, alarm, entrance doors and gates with additional sensors.

Important!
To install such a system, the boiler and other equipment must be adapted for electronic control.
Old frames with mechanical latches will not work with this scheme.

Device and principle of operation

The photo shows a 3-D model of the control unit.

Into any automatic system management includes the following nodes:

1. Sensors and sensors that collect the necessary data in various places in the system;
2. Controllers and processors that compare the data received from the sensors with the values ​​dictated by the instruction (program) recorded on the memory card, make a decision and, based on it, issue commands to the executing mechanisms;
3. Execution mechanisms that receive commands from controllers and execute simple steps- shut off taps and valves, increase the power of the units, switch modes, perform emergency shutdowns of broken units.

The sensors are pressure and temperature sensors, as well as any additional sensors that allow you to control different processes. The most important are temperature sensors for the supply and return flow of the coolant, indoor and outdoor temperature sensors, as well as pressure sensors at the inlet to the system.

The role of the controller is played by a low-power computer that reads information from all sensors. The computer memory card contains a program that determines the temperature regimes.

The controller compares the obtained values ​​with the preset ones, and, if necessary, decides to make changes: increasing the coolant supply to a particular circuit, turning off the boiler or transferring it to another operating mode, etc.

Upon making a decision, the controller sends a control signal to one or another actuator: switching relay, valve or damper servo drive, switch or boiler electronics. Depending on the given program, the GSM heating control module can send messages to the owner about a particular event, and after waiting for a response, take certain measures.

Heating control in a country house via GSM is carried out using a special module built into the computer.

This module includes the following elements:

• Slot for switching SIM-card;
• Power supply and battery;
• GSM modem;
• Antenna connector;
• LAN port for connecting to an Internet provider;
• Microprocessor;
• Memory card;
• USB connector for setup and configuration;
• LED indicators or liquid crystal display;
• Contact group with inputs and outputs for collecting data and sending control signals.

Important!
Together with the module for GSM control, a software for installation on operating system mobile phone.
The program will help organize remote communication between the controller and the operator.

Advantages

What are the benefits of using an automatic heating control unit?

A modern controller with a communication module allows you to get the following advantages and benefits:

• Fine-tuning the system in real time allows you to achieve maximum savings with the right level of comfort;
• You can achieve exactly the temperature and climatic parameters of the room that you want, and for this it is enough just to set the values ​​​​of the desired temperatures;
• The system of instant notification of emergency modes and abnormal events significantly increases the reliability and safety of work;
• You have the opportunity to leave the house with the heating working and monitor its condition at a distance, as well as control the operating modes, turn the equipment on or off remotely;
• Winter visit to Vacation home when the heating is off, it requires you to go into a cold room, melt the unit and wait a few hours until the room warms up. Now you can give a command to turn on in advance and not waste time.

You can assemble and connect the control system yourself - no permits and approvals are required for this. The job is easy to do by following the manufacturer's instructions. The price of a kit can vary from 4 to 40 thousand rubles, depending on the configuration and the manufacturer.

Important!
Most modules have connectors for connecting additional sensors, with which you can organize control over the opening of windows and doors, listening or monitoring, and other useful functions.

Conclusion

Control and management modern systems heating can be carried out by software with remote participation of the operator. Communication can be carried out by digital cellular communication GSM or the Internet. You can find more information in our video.
