The use of block heat points (BTP)

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

As a part of block heat points 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, it can be used as one module (BTP), and several, depending on the tasks, conditions and requirements necessary for the implementation by the Individual heating station:

The use of block heating units TOVK allows the installation of a (Central) Individual heating unit in a few days. At the same time, the costs of installation work should be reduced several times. The TOVK company offers the implementation of almost any project of an Individual Heating Unit (ITP) on the basis of standard modules block heat points TOVK-T... (BTP TOVK-T):

An example of using the BTP in the ITP line-up

Non-standard Block Heat Substations (BTP)

In addition to standard solutions, "TOVK" offers the implementation of an ITP 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 units (BTP) is due to several factors:

1.constrained dimensions of the premises of an individual heating point (ITP), which do not allow to place building blocks with strapping.

2. The capacity of the substation exceeds the ratings of the standard modules of the block substation.

3. complex scheme Heat point or lack thereof in standard solutions

4. Decrease in the cost of the Thermal point due to the combination of blocks or deviations from the norms.

The cost of block heat points (BTP)

When calculating the cost Individual heating point(ITP) using modules of Block Heat 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 by the very attractive price, and decides to use the modules of the block heating unit (BTP). Well, if with the price, everything is as it suggests. But unfortunately, the real total cost of the Substation using BTP modules, by most manufacturers on the market, significantly exceeds the planned cost (based on the cost of BTP). This is due to the fact that the actual cost of strapping the majority of standard modules, adapting them to each other, the device of distribution combs in the room of the Individual heating station, the organization of feeding the heating system, as well as the organization of the heating network input unit into the room of the Individual heating station, the organization of the Heat metering station. Energy (UUTE), entail costs that exceed the cost of the modules of the Block Heat Point (BTP). As a result, the estimated cost of an Individual Heating Station (IHP) can grow significantly, sometimes even several times.

When using the modules of TOVK block heating units, such costs can be reduced. All elements of the ITP are included in the composition of the proposed TOVK BTP modules. When deciding to use block heating units, we recommend:

1. Conduct consultations with the BTP manufacturer.

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

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

Let me remind you what a block heating station is and how it differs from a conventional IHP. ITP or full name individual heating point This is a set of equipment and devices that allows you to receive, take into account, regulate, distribute and deliver heat to end users, that is, to us and you and to our apartments. It is usually located v basement at the entrance to the residential apartment house.

The heating station is manufactured according to the drawings developed by the design organization, it is coordinated with all interested parties and, first of all, the heat supply organization, since the basis for the design is TU ( technical conditions) issued by this very organization.

The installation of a heating 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 prescriptions of our legislation use of block heat points so far not very common.

A fair question - why are block heat points not being used properly?

As they say .

There are several reasons for this, let's try to analyze each one.

Reason 1- project the heat supply organization does not want to agree or as we call it - heating networks.

Why? The thing is that designers are following the easiest path. Wanting to reduce the cost of design documentation (in order to win the bidding), they simply send a request for the manufacture of a block heating station to the manufacturer, and put the drawings of the commercial proposal 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 coordinated by the energy supply organization or is coordinated under pressure from power or money.

Reason 2- in most houses of the old construction (and in new ones too), the block heating point cannot be installed due to the size and weight. You can't drag it into the basement without disassembling it. Of course, no one will disassemble and re-install 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 permitted by the rules of the auction and, moreover, is prescribed for the alternative). As a result, we only receive discrediting of the idea of ​​creating a heating point in an industrial environment.

Reason 3- look who is the manufacturer of block heating units.
A manufacturer of plate heat exchangers, his goal is to market his 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 it is by no means a concern about our saving heat, but only about the sale of our products.
Where do you ask such conclusions from the analysis of 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 energy costs and major maintenance, while access to individual elements for repairs is almost always difficult, it is clear that the introduction of block ITPs, despite all their advantages, is constrained.

What to do, how to achieve the introduction of the advanced idea of ​​installing modern block heating units that save heat in our homes.

Everything is quite simple, for this you need:

• Stop saving on design documentation, the designer prepares a schematic diagram of the ITP, tie it to loads and temperature conditions, coordinate with the power supply organization and only then place an order with the manufacturer.
• The same should apply to the design of the metering unit, developed in accordance with all the rules (meaning the rules for commercial heat metering) and agreed with the heat supplier. transfer the manufacturer of block heating units .
• Suppliers of block heating units must supply their products strictly according to the schematic diagrams ITP, with a set of working documentation for which it was manufactured.
• When drawing up estimates for installation or overhaul it is necessary to take into account local conditions, if a block heating point cannot be installed without disassembly, then it must be disassembled and reassembled, taking this into account in the installation price, for this the working documentation of the manufacturer's plant will come in handy.
• Exclude permission to use from auction requirements alternative materials if the project is developed, change design solutions prohibit without agreement with the designers.
• Restore architectural supervision over the implementation of projects.
• Before concluding contracts, pay attention not only to the applicant's membership in the SRO, but also to the certification of direct executors in the technical supervision bodies, since block heating units are not internal engineering networks residential buildings, and to the device of heating networks.

The above measures will help the real, and not on paper, introduction of block heating units in our homes, which in turn will improve

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

An important feature of an individual substation is a block design. It consists of several units assembled into a single complex. This solution simplifies assembly 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 a block ITP include:

reduction of time costs for design, installation and commissioning;

hardware separation of metering and automation;

autonomy of heating, hot water supply and metering modules;

compactness;

the possibility of remote control and management of heat consumption modes;

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

lower maintenance costs, Maintenance and prevention.

Separately, it should be noted that an individual heating point provides the building with independence from district 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 point is installed in an apartment building.

The main units of an individual heating point

Such a complex includes the following components:

heat carrier preparation unit - is responsible for connecting to the heating network, cleaning the heat carrier and measuring the main technological parameters;

water preparation unit for the hot water supply system - maintains the standard water temperature and provides water supply to the consumer;

heat supply control unit - in automatic mode in accordance with the schedule or information coming from the sensors, provides a comfortable microclimate at the facility, and this is not only about increasing the temperature, but, if necessary, also about lowering;

heat and coolant metering unit is a system that controls heat consumption and consumption of water and electricity.

The work of an individual heat point is automated. It can be equipped with devices that allow you to remotely receive information about the parameters of the supplied heat and, if necessary, adjust the operating mode.

The company "LAiN Technologies" offers individual heating points, which include reliable equipment, metering devices and automated control systems. it ready-made solutions that can be changed according to the needs of the customer. We guarantee fast delivery and prompt installation, carry out commissioning, carry out service maintenance... If you have any questions, please contact us! Our experts will provide the necessary consultations and help you make the right choice, taking into account such parameters as the area of ​​the room, installation possibilities, the object's need for heat, etc.

Heating, which already exists, new objects, residential buildings, etc. In addition to heating supply, it is also possible to supply hot water and connect the object to such communications as sewerage.

General description of BTP

Block (BTP) is a complete unit, ready for operation. It is important to know here that the arrangement by any devices for each item is carried out 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 same 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 the usual engineering heating network of the building. There is a general Danfoss calculation program for substations. It is worth noting that this is one of the most large manufacturers 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:

• Accounting and regulation unit. This unit is designed to keep track of the actual flow rate of the coolant and heat. In addition, he is engaged in adjusting the flow rate of the thermal 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.
• Node This device is designed to maintain optimal temperature water in the system (55-60 degrees Celsius) and its supply to the consumer. Also, this node is responsible for carrying out the heat treatment operations of the system.
• Ventilation unit. This system is designed to regulate the consumption of supplied heat energy to the consumer, depending on weather conditions, as well as the time of day.

BTP device

Block heat point is automated installation, which is designed to transfer energy coming from a boiler house, thermal power plant, RTS to heating, as well as ventilation and hot water supply lines that are 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 heating point, then it must be large enough to accommodate all block equipment, as well as control and measuring instruments necessary for the functioning of the system. All these devices are needed so that the TP can perform such functions as:

• transformation of the coolant;
• 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;
• keeps records of consumed heat and coolant.

Variety of systems

According to their characteristics and reception of heat sources, TP are divided into types. The first type refers to open system... In this case, the liquid enters the BTP directly from the coolant, and the entire volume of liquid that goes to the operation of the equipment is replenished due to the full or partial intake of water.

By its type of connection to the system open views BTP can be divided into two groups:

• Dependent schema. 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 no additional equipment is required. However, without it, there is no possibility of adjusting the heat supply at this unit.
• Independent scheme. In such a system, there are devices such as heat exchangers between the consumer and the heating plant 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 advantages of installing a BTP?

The installation of an automated block heating point can give the system several of the following advantages:

1. Increases the efficiency of the network. The ability to adjust the heat consumption on site increases the overall heat savings by about 15%.
2. Automation of the control process. The equipment has thermal relays, which 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.
3. Reduced material costs. Since the installation is automated system, then fewer personnel are required in order to monitor its work, monitor the state of thermal elements, carry out preventive maintenance or repairs, etc. In total, all this can reduce the cost of material resources by about three times.
4. Even with high productivity (up to 2 Gcal / hour), this equipment is compact. The approximate area that will have to be allocated for the BTP is 20-25 m 2.

Manufacturer Danfoss

The purchase of block transformer substations from such large manufacturers has its own advantages. For example, one of the main differences from other manufacturers is that the equipment is delivered to the installation site ready-made. That is, it is not necessary to assemble the unit, which significantly increases the speed of installation and connection. One of these advantages is also the fact that Danfoss plants can be operated in a fully automatic mode.

In order for the equipment to work in this mode, you just need to set desired values temperature and pressure. The regulating and monitoring devices will continue to maintain the specified operating mode. It is also worth adding that there is a possibility of individual configuration according to the buyer's order. You can add an accounting system, a system remote control devices, etc.

Heat points SP 41-101-95

This paper is a document according to which the design of the heating point is carried out. All the rules that are spelled out in this paper apply to such TP, the characteristics of which fall under the given ones: hot water pressure up to 2.5 MPa, liquid temperature up to 200 degrees Celsius. If the unit operates with steam, then its nominal operating pressure should be within the range of up to 6.3 MPa, and the temperature should not exceed 440 degrees Celsius.

For this joint venture, heating points are divided into two main categories - individual or central. Individual TPs 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 ITPs, with the only difference that they are used for several buildings at once.
