Block individual heating point. What is a block heating substation? A well-thought-out technical solution

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

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 information from the metering unit and the heating and hot water supply controller to a single control center. 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:

  • Automatic electronic system regulation of heating circuits
  • Circulation and booster pumps for heating and hot water circuits
  • Instrumentation
  • Shut-off and control valves
  • Thermal energy metering unit
  • Magnetic mesh filters and magnetic water treatment devices
  • Automatic control and dispatch system

Based on practical experience in implementing energy-saving equipment, Teploeffekt CJSC offers more than 40 ready-made unified standard schemes new solutions for the constructive manufacturing of modular BITP. Ready design solution allows you to complete the design and manufacture of equipment in the shortest possible time, as well as reduce the cost of manufacturing an automated heating station.


Advantages

BITP are fully automated, which reduces operating costs by 40-50%. Due to the use of an automatic control system, thermal energy consumption at facilities is reduced to 30%, as a result, the economic efficiency of using BITP ranges from 10 to 25%, the payback period of the equipment is 1-2.4 years.

The installation time for heating units is reduced by 4-5 times due to the use of factory-ready installation blocks.

The economic effect of implementation is due to

Increasing reliability, reducing maintenance costs, simplifying and reducing the cost of pipelines and fittings within heating points.

Reducing thermal energy losses by reducing the area and temperature of the outer surface of heat exchangers.

Reducing thermal energy losses by increasing the heat transfer coefficient of heat exchangers, reducing the required temperature pressure and coolant consumption for heating water.

Reducing the consumption of thermal energy in the heating system through the introduction of efficient automatic system façade-by-façade regulation of fuel consumption based on outside air temperature.


Cabinet heating unit

The substation is delivered assembled in a container made of metal corrugated sheeting with insulation and does not require additional construction installation work. The pipeline outlets are located outside the container.

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 its block design. 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:

The use of a block individual heating point allows for analysis and optimization of energy consumption, as well as minimizing operating and capital costs. The transition to modular ITP will help to effectively solve the issue of expedient and economical consumption of energy resources.

The equipment that is equipped with a block ITP is installed on a frame and tied with pipelines or in a block container, which is a structure made of metal frame and partitions made of sandwich panels. Each block module is equipped with lighting, heating and ventilation systems. It is possible to equip the installation with a dispatch point with automatic information output and fire and security alarm.

Schematic diagram of ITP

The most commonly used scheme for connecting a consumer to a heating network is an independent scheme for connecting a heating circuit and open system hot water supply.

The supply pipeline of the heating network supplies the coolant to the heat exchangers of heating and hot water supply systems, in which thermal energy is transferred from the coolant of the heating network to the coolant of the heating and hot water supply system. After this, the coolant enters the return pipeline, from where it is returned for reuse to the heat-generating enterprise (boiler house or thermal power plant) through the main networks.

The heating circuit is closed system. The coolant circulates through the heating circuit circulation pumps. During operation (functioning) of the system, a coolant leak may occur, which is compensated by the make-up line.

Tap water, having passed through the cold water supply pumps, is divided into 2 parts: one is sent to consumers, the other is supplied to the circulation circuit of the hot water supply system after heating in the first stage DHW heater. In this circuit, water moves in a circle, the specified level of its temperature is maintained in the heaters of the second stage of DHW.

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, the costs of installation work will be reduced 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)

Except standard solutions, "TOVK" offers the implementation of the 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 premises of an individual heating unit (IHP), 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(IHP) 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 it is not always the case. Having learned the cost of BHP modules, the Customer is pleasantly surprised at the very attractive price and decides to use block heat substation (BHP) modules. 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 replenishment 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 significantly.

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

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