Application of Block heat points (BTP)
Block heat points TOVK (BTP TOVK) are certified modules used in Individual heating point (ITP) and subdivided according to purpose, power and coolant used: Water, Steam, Ethylene glycol.
As part of the block heating substations of TOVK, applied plate heat exchangers. Block heat points TOVK can be fully automated both individually and as part of a heat point.
As part of the ITP can be used as one module (BTP), and several, depending on the tasks, conditions and requirements necessary for the implementation of the Individual heating point:
The use of TOVK Block Heat Substations makes it possible to install a (Central) Individual Heat Substation in a few days. At the same time, the cost of installation work will be reduced several times. The TOVK company offers the implementation of almost any project of an Individual heating point (ITP) based on standard modules block heat substations TOVK-T. (BTP TOVK-T):
An example of using BTP in the ITP layout
Non-standard block heating points (BTP)
In addition to standard solutions, "TOVK" offers the implementation of an IHP project using non-standard modules of a block heating unit (BTP), manufactured and adapted for installation (assembly) according to an existing project, taking into account all its features and requirements.
As a rule, the use of non-standard modules of block heating points (BTP) is due to several factors:
1. cramped dimensions of the premises of an individual heating point (ITP), which do not allow placing standard blocks with piping.
2. The power of the heat substation exceeds the ratings of the standard modules of the block heat substation.
3. complex scheme Heat point or lack thereof in standard solutions
4. reduction in the cost of the Heat Substation due to the combination of blocks or deviations from the norms.
The cost of block heating points (BTP)
When calculating the cost Individual heating point(ITP) using modules of Block Heating Points (BTP), it is necessary to take into account the cost of piping the modules used in the project. The name itself is misleading - Block heat point. This usually sounds like a complete solution. But it is not always the case. Having learned the cost of BTP modules, the Customer is pleasantly surprised attractive price, and makes a decision on the use of modules of a block heat substation (BTP). Well, if with a price, everything is as it suggests. But unfortunately, the real total cost of the Heat Substation using BTP modules, by most manufacturers on the market, significantly exceeds the planned cost (based on the cost of the BTP). This is due to the fact that the actual cost of tying most standard modules, adapting them to each other, installing distribution manifolds in the room of the Individual heating point, organizing the replenishment of the heating system, as well as organizing the node for entering the heating network into the room of the Individual heating point, organizing the Heat Metering Unit Energy (UHTE), entail costs exceeding the cost of modules of the Block Heat Substation (BTP). As a result - estimated cost An individual heating point (ITP) can grow significantly, sometimes even at times.
When using the modules of TOVK Block Heat Substations, such costs can be reduced. The BTP modules offered by TOWC include all elements of the ITP. When deciding to use block heat points, we recommend:
1. Consult with the BTP manufacturer.
2. Rate total cost an individual heating point in the composition with BTP modules (including the cost of installation work).
3. Assess compatibility overall dimensions blocks (modules) of BTP with dimensions of the room and doorways, the possibility of partial disassembly of blocks (modules) if necessary.
4. Make sure that the layout of equipment and pipelines in the modules of the block heat substation allows (provides) the possibility of unhindered access to maintenance and replacement of equipment after installation and commissioning of the installed heat substation.
Heating that already exists, new facilities, residential buildings etc. In addition to the heating supply, it is also possible to supply hot water and connect the object to such communications as sewerage.
General description of the BTP
Block (BTP) is a complete installation ready for operation. Here it is important to know that the layout of any devices for each item is carried out in individually. The main characteristic that specialists rely on when assembling the unit is the size of the room in which the object will be installed.
The very production of a block point is carried out through the use of basic schemes, on the basis of which it is possible to connect this equipment to a conventional engineering heating network of a building. There is a general Danfoss calculation program for heat substations. It should be noted that this is one of the fairly large manufacturers of block heat points.
Equipment
If we talk about the most common configuration of the BTP, which is considered standard, then it includes such elements as:
- Node of accounting and regulation. This node is designed to keep records of the actual flow of coolant and heat. In addition, he is engaged in adjusting the flow of the heat carrier in accordance with a given temperature schedule.
- Heating unit. This element is responsible for the consumption of thermal energy, taking into account weather conditions, time of day and other conditions.
- Assembly This device is designed to maintain optimal temperature water in the system (55-60 degrees Celsius) and its supply to the consumer. This node is also responsible for carrying out operations on heat treatment systems.
- Ventilation unit. This system is designed to regulate the consumption of supplied thermal energy to the consumer, depending on weather conditions, as well as the time of day.
BTP device
A block heat point is an automated installation that is designed to transfer energy from a boiler house, thermal power plant, RTS to heating, as well as ventilation and hot water supply lines connected to residential or industrial buildings. In other words, it is a local intermediary between the station and the consumer.
If we talk about the room in which it is planned to install a block heat point, then it must be large enough to accommodate all block equipment, as well as control and measuring instruments necessary for the operation of the system. All these devices are needed so that the TP can perform functions such as:
- coolant conversion;
- regulation, control and change of thermal values;
- distribution of the coolant in group or individual systems;
- plays the role of a fuse if the temperature rises above the maximum value;
- maintains records of consumed heat and coolant.
Variety of systems
According to their characteristics and the reception of heat sources, TS are divided into types. The first type refers to open system. In this case, liquid enters the BTP directly from the coolant, and the entire volume of liquid that goes into the operation of the equipment is replenished due to full or partial water intake.
According to the type of connection to the system open views BTP can be divided into two groups:
- dependent scheme. In such a system, the coolant is supplied directly to the heating system. The advantages of the scheme include its simplicity, as well as the fact that it does not require the supply of additional equipment. However, without it, there is no possibility of adjusting the heat supply at this node.
- independent scheme. In such a system, there are devices such as heat exchangers between the consumer and the thermal station itself. With their help, it is possible to regulate the supply of the heat source, which helps to save up to 40% of energy.
What are the benefits of installing a BTP?
Installing an automated block heat substation can provide the system with several of the following benefits:
- Increases network efficiency. The ability to adjust the heat consumption on site increases the overall savings in heat energy by about 15%.
- Automation of the control process. The equipment has thermal relays that make it possible to configure the equipment in such a way as to compensate for weather conditions, as well as change the operating mode in accordance with the time of day.
- Reducing material costs. Since the installation is automated system, then less personnel is required in order to monitor its work, control the condition of thermal elements, conduct preventive work or repair, etc. In sum, all this can reduce the cost of material resources by about three times.
- Even with high performance(up to 2 Gcal/hour), this equipment refers to compact. An approximate area that will have to be allocated for BTP is 20-25 m 2.
Manufacturer Danfoss
The purchase of block transformer substations from such large manufacturers has its advantages. For example, one of the main differences from other manufacturers is that the equipment is delivered to the installation site already ready-made. That is, it is not necessary to assemble the unit, which significantly increases the speed of installation and connection. Among these advantages, one can also highlight the fact that Danfoss installations can be operated in full automatic mode.
In order for the equipment to work in this mode, you just need to set the desired temperature and pressure values. Regulating and monitoring devices will continue to maintain the specified mode of operation. It is also worth adding that there is the possibility of individual configuration by order of the buyer. You can add an accounting system, a remote device control system, etc.
Thermal points SP 41-101-95
This paper is a document according to which the design of the heat point is carried out. All the rules that are written in this paper apply to such TP, the characteristics of which fall under the specified ones: hot water pressure up to 2.5 MPa, liquid temperature up to 200 degrees Celsius. If the installation works with steam, then its conditional operating pressure should be within the range of up to 6.3 MPa, and the temperature should not exceed 440 degrees Celsius.
According to this joint venture, heat points are divided into two main categories - these are individual or central. Individual TS are intended to join the heating, water supply and ventilation system of one building or part of it. Central TPs are intended for the same as the ITP, but with the only difference that they are used for several buildings at once.
Individual heating point (ITP), Central heating point (CTP)
Block heat point (or individual heat point) - a way to reduce energy costs. One of the priorities of our company is the assembly, supply and installation of automated block heat points for energy enterprises, housing and communal services (HCS), municipal unitary enterprises(MUP), management companies (UK), various industrial enterprises and design organizations.

Flexible system of discounts and wide selection components favorably distinguish our block individual heating points from others.
Purpose heat points
Currently, more and more attention is paid to the issues of energy saving and payment for energy carriers. A particularly difficult situation is observed in the heat payment system, when the consumer pays for losses in heating mains that do not belong to him, which reach, and sometimes exceed, 20% of the volume of heat transferred. As a result, a decrease in winter time air temperature in residential and industrial premises due to underheating of water in the systems district heating and continuous growth financial costs for heat supply due to the increase in tariffs for thermal energy. A promising approach to resolving the current situation is the commissioning of automatedblock heating points (BTP).

Description of heat points
Heat points subdivided into :
- individual heating point(ETC) used to connect heating, ventilation, hot water and other thermal installations of one building or part of it.
- central heating point (CTP) for two buildings or more, performing the same functions as the ITP.
More and more wide application find heat points manufactured on a single frame in a modular design of high prefabrication, which are called block ( BTP).
BTP is a complete factory product, designed to transfer thermal energy from a thermal power plant or boiler house to a heating, ventilation and hot water supply system.
As part of the BTPincludes the following equipment: heat exchangers, controller (electrical control panel), direct-acting regulators, electric control valves, pumps, instrumentation (CIP), shut-off valves other.
Instrumentation and sensors provide measurement and control of the coolant parameters and give signals to the controller about the parameters going beyond the permissible values.
The controller allows you to control the following BTP systems in automatic and manual mode:
- a system for regulating the flow, temperature and pressure of the heat carrier from the heating network in accordance with the technical
heat supply conditions
- temperature control system of the heat carrier supplied to the heating system, taking into account the temperature
outdoor air, time of day and working day
- a system for heating water for hot water supply and maintaining the temperature within the limits of sanitary standards
- a system for protecting the circuits of the heating and hot water supply system from emptying during scheduled shutdowns for repairs or
network failures
- DHW water storage system, which allows to compensate for peak consumption during peak hours
loads
- system of frequency regulation of the drive by pumps and protection against "dry running"
- system of control, notification and archiving of emergency situations and others.
Execution BTP varies depending on the application used in each separate case schemes for connecting heat consumption systems, the type of heat supply system, as well as specific technical conditions of the project and the wishes of the customer.

Application of shell-and-tube and plate heat exchangers in BTP
ATheat points Most buildings typically have shell-and-tube heat exchangers and direct acting hydraulic controls. In most cases, this equipment has exhausted its resource, and also operates in modes that do not correspond to the calculated ones. The latter circumstance is due to the fact that the actual thermal loads are currently maintained at a level significantly below the design level. The control equipment does not perform its functions in case of significant deviations from the design mode.
When reconstructing heating systems, it is recommended to use modern equipment, characterized by compactness, providing for operation in a fully automatic mode and providing savings of up to 30% of energy, compared with equipment used in the 60-70s. In modern heat points, an independent scheme for connecting heating and hot water supply systems is usually used, made on the basis ofcollapsible plate heat exchangers .
To control thermal processes are used electronic regulators and specialized controllers. Modern plate heat exchangers are several times lighter and smaller than shell-and-tube heat exchangers of the same capacity. The compactness and low weight of plate heat exchangers greatly facilitate installation, maintenance and Maintenance heating equipment.
The calculation of plate heat exchangers is based on a system of criterion equations. However, before proceeding with the calculation of the heat exchanger, it is necessary to calculate the optimal distribution of the DHW load between the stages of the heaters and the temperature regime of each stage, taking into account the method of regulating the heat supply from the heat source and the schemes for connecting the DHW heaters.
Our company has its own proven program of thermal and hydraulic calculation, allowing you to select lamellar brazed and collapsible heat exchangers that fully meet the requirements of the customer.
Production blocal heating points
The basis of a block heating point is made up of collapsible plate heat exchangers, which have proven themselves in tough Russian conditions. They are reliable, easy to maintain and durable. Heat meters are used as a node for commercial heat metering, which have an interface output to the upper control level and allow reading the consumed amount of heat. To maintain the set temperature in the hot water supply system, as well as to regulate the temperature of the coolant in the heating system, a two-circuit regulator is used. The control of the pumps, data collection from the heat meter, control of the regulator, control of the general condition of the BTP, communication with the upper level of control (dispatching) is taken over by the controller, which is compatible with a personal computer.
The regulator has two independent circuits for regulating the temperature of heat carriers. One provides temperature control in the heating system depending on the schedule, taking into account the outdoor temperature, time of day, day of the week, etc. The other maintains the set temperature in the hot water supply system. You can work with the device both locally, using the built-in keyboard and display panel, and remotely via the interface communication line.
The controller has several discrete inputs and outputs. Discrete inputs receive signals from sensors related to the operation of pumps, penetration into the premises of the BTP, fire, flooding, etc. All this information is delivered to the upper dispatching level. The discrete outputs of the controller control the operation of pumps and regulators according to any user algorithms specified at the design stage. It is possible to change these algorithms from the top management level.
The controller can be programmed to work with a heat meter, providing data on heat consumption in control room. Through it, communication with the regulator is carried out. All devices and communication equipment mounted in small closet management. Its placement is determined at the design stage.
In the vast majority of cases, when reconstructing old heat supply systems and creating new ones, it is advisable to use BTP block heat points.
Blockheat points assembled and tested in the factory, have high reliability. Installation of equipment is simplified and cheaper, which ultimately reduces the overall cost of renovation or new construction. Each project of a block heat point is individual and takes into account all the features of the customer's heat point: structure heat consumption, hydraulic resistance, schematic solutions of heating points, permissible pressure losses in heat exchangers, room dimensions, quality tap water and much more.Our company performs the following types works:

Block heat point, Individual heat point, Central heat point
Let me remind you what a block heat point is and how it differs from a conventional ITP. ITP or full name individual heating point is a complex of equipment and devices that allows you to receive, take into account, regulate, distribute and deliver heat end users, i.e. to us and to our apartments. It is usually located in basement at the entrance to the residential apartment house.
The heat point is manufactured according to the drawings developed by the design organization, is consistent with all interested parties and, first of all, the heat supply organization, since the technical specifications serve as the basis for the design ( specifications) issued by that organization.
The installation of a heat point is usually carried out in the same basement, one might say in a handicraft way, right on the knee, of course, if the same heat point is made in the factory, its quality will be an order of magnitude higher, and meanwhile, despite all the recommendations and regulations of our legislation use of block heating points
so far not widespread.
A fair question - why block heat points do not receive proper use?
As they say .
There are several such reasons, let's try to analyze each.
Reason 1- project does not want to agree heat supply organization or as we usually call it - thermal networks.
Why? The thing is that the designers go on their own easy way. Wanting to reduce the cost project documentation(in order to win the auction), they simply send a request for the manufacture of a block heating unit to the manufacturer, and put the drawings of the commercial offer into the project under the proud name - ITP.
The manufacturer also issues standard documentation, without proper reference to local conditions and loads. It is not possible to make one product for all occasions. As a result, such a project is not agreed upon by the energy supplying organization or is agreed under pressure from government or money.
Reason 2- in most old-built houses (and in new ones too), a block heat point cannot be installed due to its size and weight. Without disassembly, you can’t drag it into the basement. Of course, no one will disassemble and re-mount it either, only weight and connection are taken into account in the installation price. So a "parody" of a block ITP is being made right on the spot, from completely different equipment (by the way, this is allowed by the rules of the auction and, moreover, prescribed for an alternative). As a result, we only get a discredit of the idea of creating a heat point in an industrial environment.
Reason 3– see who is the manufacturer of block heat points.
Manufacturer of plate heat exchangers, its purpose is to market its products.
The manufacturer of heat meters - the goal is also clear and the manufacturer of automation equipment for thermal processes, the goal is also clear and this is by no means a concern for our heat savings, but only for the sale of our products.
Where do you ask such conclusions, from the analysis commercial offers. In the block heat points offered for sale, there is always a surplus of the supplier's products.
Considering that block ITP require mandatory fixed costs for electricity and major maintenance, while access to individual elements for repair is almost always difficult, it is clear that the introduction of block ITPs, despite all their advantages, is being held back.
What to do, how to achieve the introduction of the advanced idea of installing modern block heat points that save heat in our homes.
Everything is quite simple, for this you need:
- Stop saving on project documentation, the designer should prepare a schematic diagram of the ITP, link it to the loads and temperature conditions, coordinate with the power supply organization and only after that place an order with the manufacturer.
- The same should apply, namely, the draft metering unit developed in accordance with all the rules (meaning the rules for commercial heat metering) and agreed with the heat supplier is necessary transfer the manufacturer of block heat points .
- Suppliers of block heat substations must supply their products strictly according to the circuit diagrams ITP, with a set of working documentation, according to which it was made.
- When preparing estimates for installation or overhaul it is necessary to take into account local conditions, if the block heating point cannot be installed without dismantling, then it must be disassembled and reassembled, taking this into account in the installation price, and for this it will come in handy working documentation manufacturer.
- Exclude from the auction requirements permission to use alternative materials, if the project is developed, change design solutions prohibited without the consent of the designers.
- Restore architectural supervision over the implementation of projects.
- Before concluding contracts, pay attention not only to the membership of the applicant in the SRO, but also to the certification of direct executors in the technical supervision bodies, since block heat points are not internal engineering networks residential buildings, but to the device of thermal networks.
The measures listed above will help real, and not on paper, the introduction of block heat points in our homes, which in turn will improve
