An individual heating point (IHP) is a ready-made set of equipment with which you can receive, account for, regulate, distribute and deliver heat to end consumers. It can be used to organize the most efficient and comfortable heating and hot water supply for various objects: residential apartment buildings, office, industrial and administrative buildings.

An important feature of an individual heating point is block construction. It consists of several nodes assembled into a single complex. This solution simplifies installation work and makes it possible to flexibly change the ITP in accordance with the tasks facing the building owner. Repairs and upgrades are also faster and easier.

Advantages of individual heating points

The advantages of block ITP include:

reduction of time costs for design, installation and commissioning;

hardware separation of accounting and automation means;

autonomy of heating, hot water supply and metering modules;

compactness;

possibility of remote monitoring and control of heat consumption modes;

ease of maintenance - all elements are easily accessible for inspection and replacement, and the heat exchanger is easy to clean;

reduction in maintenance costs, current repairs and prevention.

Separately, it is worth noting that an individual heating unit provides the building with independence from central heating and hot water supply. This means that you can, if necessary, turn on the heat supply even in summer, set the operating mode in accordance with the time of day, set special operating modes for weekends and holidays. All this not only contributes to savings, but also increases the level of comfort in the building, which is especially important if an individual heating unit is installed in an apartment building.

Main components of an individual heating point

This complex includes the following components:

coolant preparation unit - responsible for connecting to the heating network, cleaning the coolant and measuring basic technological parameters;

Application of Block Heat Substations (BTP)

Block heat substations TOVK (BTP TOVK) are certified modules used in the composition Individual heating point (ITP) and divided by purpose, power and coolant used: Water, Steam, Ethylene glycol.

As part of TOVK block heating units, plate heat exchangers. TOVK block heating units can be fully automated, both individually and as part of a heating unit.

As part of the ITP it can be used as one module (BTP), and several, depending on the tasks, conditions and requirements required to be fulfilled by an Individual Heating Point:

The use of TOVK block heating units allows for the installation of a (Central) Individual heating unit in a few days. At the same time, implementation costs installation work, reduce several times. TOVK company offers the implementation of almost any Individual Heating Point (IHP) project based on standard modules block heating units TOVK-T. (BTP TOVK-T):

An example of using a BTP in an ITP layout

Non-standard Block Heat Substations (BTP)

In addition to standard solutions, TOVK offers the implementation of an IHP project using non-standard modules of a block heat substation (BHP), 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 Heat Points (BHP) is due to several factors:

1. cramped dimensions of the individual heating unit (IHP) premises, which do not allow the placement of standard units with piping.

2. The power of the heating unit exceeds the ratings of standard modules of a block heating unit.

3. complex circuit Heating point or lack thereof in standard solutions

4. reducing the cost of the Heating Point by combining blocks or deviating from the norms.

Cost of Block Thermal Points (BTP)

When calculating the cost Individual heating point(ITP) using modules of Block Heat Points (BHP), it is necessary to take into account the cost of piping the modules used in the project. The name itself is misleading - Block Heating Point. Typically this sounds like a complete solution. But this is not always the case. Having learned the cost of BTP modules, the Customer is very pleasantly surprised attractive price, and decides to use modules of a block heat substation (BHP). Well, if with the price, everything is as he suggests. But unfortunately, the real final cost of a Heating Point using BTP modules from 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 piping most standard modules, adapting them to each other, installing distribution combs in the premises of an Individual Heating Point, organizing recharge of the heating system, as well as organizing a heating network input unit into the premises of an Individual Heating Point, organizing a Heat Metering Unit Energy (UUTE) entail costs that exceed the cost of the Block Heat Substation (BHP) modules. As a result, the estimated cost of an Individual Heating Point (IHP) can increase significantly, sometimes even by several times.

When using modules of TOVK Block Heating Points, such costs can be reduced. The BTP modules offered by TOVK include all elements of the ITP. When deciding to use block heating units, we recommend:

1. Consult with the manufacturer of the PFC.

2. Rate total cost individual heating point combined with BTP modules (including the cost of installation work).

3. Assess compatibility overall dimensions BTP blocks (modules) with room dimensions 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 station allows (provides) the possibility of unhindered access to maintenance and replacement of equipment after installation and commissioning of the installed heat station.

A block-modular individual heating point is an installation used to transfer thermal energy from an external heating network to various consumer heat supply systems.

An individual heating point allows you to connect reconstructed or newly constructed facilities to heating networks in the shortest possible time. BITP has an automatic control system that allows for weather compensation, setting day or night operating modes, holiday and weekend modes. Each BITP is equipped with a set of means for remote data transmission via a switched line, via GSM communication or the Internet and provides the ability to output to a single control center information from the metering unit and heating and hot water supply controller. At the same time, a mnemonic diagram of the parameters of the heating unit in the operating mode is displayed on the dispatcher’s monitor.

Design

BITP consists of a heating module, hot water supply and a thermal energy consumption metering unit. The use of a modular design allows you to reduce the time required for the manufacture and installation of a heating unit. In addition to plate heat exchangers, the heating unit includes:

Purpose heating points

Currently, more and more attention is being paid to issues of energy saving and payment for energy resources. 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 transferred heat. As a consequence, a decrease in winter time air temperature in residential and production premises due to underheating of water in district heating systems and the continuous increase in financial costs for heat supply due to increased tariffs for thermal energy. A promising approach to resolving the current situation is the commissioning of automatedblock heating points (BTP).

Description of heating points

Heating points are divided into :

- individual heating point(ITP), used to connect heating, ventilation, hot water supply and other thermal installations of one building or part of it.

- central heating point (TsTP) for two or more buildings, performing the same functions as ITP.

Heating points manufactured on a single frame in a modular design with high factory readiness, which are called block units, are increasingly used. BTP).
BTP is a complete factory product designed to transfer thermal energy from a thermal power plant or boiler room to a heating, ventilation and hot water supply system.

Included in the BTPincludes the following equipment: heat exchangers, controller (electrical control panel), regulators direct action, electric control valves, pumps, instrumentation, shut-off valves and others.
Instrumentation and sensors provide measurement and control of coolant parameters and issue signals to the controller when parameters go beyond acceptable values.

The controller allows you to control the following BTP systems in automatic and manual mode:
- system for regulating the flow, temperature and pressure of the coolant from the heating network in accordance with technical specifications
heat supply conditions
- system for regulating the temperature of the coolant supplied to the heating system, taking into account the temperature
outside air, time of day and working day
- system for heating water for hot water supply and maintaining the temperature within sanitary standards
- a system for protecting the heating and hot water system circuits from emptying during planned stops for repairs or
accidents in networks
- accumulation system DHW water, allowing you to compensate for peak consumption during peak hours
loads
- frequency control system for pump drives and protection against “dry running”
- system for monitoring, warning and archiving of emergency situations and others.

Execution BTP varies depending on the connection schemes for heat consumption systems used in each individual case, the type of heat supply system, as well as specific technical specifications project and customer wishes.

Application of shell-and-tube and plate heat exchangers in BHP

INheating points Most buildings typically have shell-and-tube heat exchangers and direct-acting hydraulic controls. In most cases, this equipment has exhausted its service life and also operates in modes that do not correspond to the design ones. The latter circumstance is due to the fact that actual heat loads are currently maintained at a level significantly lower than the design one. In case of significant deviations from the design mode, the control equipment does not perform its functions.

When reconstructing heat supply systems, it is recommended to use modern equipment, which is compact, provides for operation in a fully automatic mode and provides energy savings of up to 30% compared to equipment used in the 60-70s. Modern heating points usually use an independent connection scheme for heating and hot water supply systems, based ongasketed plate heat exchangers .

Electronic regulators and specialized controllers are used to control thermal processes. Modern plate heat exchangers several times lighter and smaller than shell-and-tube machines of corresponding power. The compactness and low weight of plate heat exchangers greatly facilitate the installation, maintenance and routine repair of heating point 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 heater stages and temperature regime each stage, taking into account the method of regulating heat release from the heat source and connection diagrams for DHW heaters.

Our company has its own proven thermal and hydraulic calculation, which allows you to select brazed and gasketed plate heat exchangers that fully satisfy customer requirements.

Production blocal heating points

The basis of the block heat station is made up of collapsible plate heat exchangers, which have proven themselves to be excellent in harsh Russian conditions. They are reliable, easy to maintain and durable. Heat meters are used as commercial heat metering units that have an interface output to the upper control level and allow reading the consumed amount of heat. To maintain set temperature In the hot water supply system, as well as in regulating the temperature of the coolant in the heating system, a dual-circuit regulator is used. Controlling the operation of pumps, collecting data from the heat meter, controlling the regulator, monitoring the general condition of the battery pump, communication with the upper level of control (dispatching) is performed by a controller that is compatible with a personal computer.

The regulator has two independent coolant temperature control circuits. One provides temperature control in the heating system depending on the schedule, taking into account the outside air temperature, time of day, day of the week, etc. The other supports set temperature in the hot water supply system. You can work with the device either locally, using the built-in keyboard and display panel, or remotely via an interface communication line.

The controller has several discrete inputs and outputs. The discrete inputs receive signals from sensors regarding the operation of pumps, penetration into the BTP premises, fire, flooding, etc. All this information is delivered to the upper dispatch level. Through the discrete outputs of the controller, the operation of pumps and regulators is controlled 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 heat consumption data to the control center. It also communicates with the regulator. All instruments and communication equipment are 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 block heat substations BTP.
