Heat points built into buildings should be placed. Requirements of the norms concerning the premises of the heating point. premises for production and technical purposes and warehouse

Individual heating points (ITPs) include detached small buildings or isolated rooms in which various elements of equipment supplying heat to buildings (points of consumption) are located.

The object allows:

• connect to a centralized heat supply network, water supply, electricity;
• use different coolants;
• modify the structure at any time;
• manage the level of consumption of thermal energy;
• set modes.

Such installations show high performance, long service life and convenience. Power supply is necessary for the operation of pumping units.

What is included in the general tasks of the system

The purpose of an individual heat point is to perform a number of tasks and functions.

The direction of use is to provide premises:

• good ventilation;
• hot water;
• heating the premises of residential buildings, municipal administrations, as well as industrial enterprises, organizations and entire complexes.

The tasks are as follows - the ITP should:

1. Consider how much heat and its carrier consumes.
2. Protect thermal system from an excess of coolant in the parameters. Otherwise, it may lead to emergency situations.
3. Shut down consumer systems in a timely manner.
4. Evenly distribute the passage of the coolant inside the system.
5. To carry out control and adjustment functions over the liquid circulating through pipes and radiators.
6. Ensure the successful conversion of one coolant into another form. For example, make the transition from water to antifreeze or propylene glycol.

If we talk about small installation options, then they are quite suitable for servicing a residential building for one average family, or a small building for an office, office, etc. When it comes to large-scale installations, they are already supplying heat for apartment buildings and large buildings. Such points and power have a large 50 kW - 2 MW.

Advantages of individual heating points

The advantages of the well-coordinated work of the automated ITP converter include:

1. Obvious savings in cash costs - 40-60% less than the cost of maintaining and using the installation alone.
2. Reduced heat consumption by 30% compared to non-automated points.
3. The accuracy of mode adjustment brings the reduction of heat loss to 15%.
4. Noiseless at work.
5. Compactness in installation and its connection with the load. For example, an aggregate system with a capacity of up to 2 Gcal / h will have an area of ​​​​only 25-30 sq.m.
6. Ease of placement - you can equip the basement of any building.
7. Automation of the workflow, which leads to a reduction in the number of staff.
8. Service operators do not have to be highly qualified in the position.
9. The ability to set the optimal modes on different days - holidays, weekends, during periods of difficult weather conditions.

Such items effectively save energy, serve as a means to ensure comfort in the room. Manufacturers often produce such systems to order, which allows them to be designed as conveniently as possible on an individual basis.

Accounting devices

The metering device allows you to correctly calculate the amount of consumed thermal energy that is necessary for the settlement interaction between the enterprise providing services and the subscriber consuming them. This eliminates the risk of overestimation of load values ​​by heat suppliers. Metering devices are needed for the following operations:

1. Creation of comfortable relations of the company with customers-subscribers in the form of accurate mutual settlements.
2. Maintaining a documented history of the operating parameters of the system (pressure, coolant flow, and temperature).
3. Rational use of the entire energy supply system - hydraulics, thermal conditions and control over it.

The meter comes with the following:

• counter;
• manometer and tanometer;
• converters - for consumption and supply;
• filter (mesh-magnetic).

How is it served:

1. The reader is turned on and readings are taken.
2. Conduct an analysis.
3. Find out the reasons for failures.
4. Check seals for integrity.
5. Do the analysis again.
6. Check and compare temperature readings using thermometers on pipelines.
7. Checking ground contacts.
8. Replenishment of oil in the sleeves.
9. Cleaning filters and other areas from dirt and dust.

Structural scheme

Design nodes:

• accounting device;
• input from the heating system;
• points for connection - ventilation, heating, hot water;
• area for matching pressure between supply and consumption levels;
• independent power supply circuit from heating or ventilation (selected as an option).

Types of IHS by type of thermal energy consumption systems

Systems can be used standard, or can be made combined. So the classic options for selecting heat supply systems are as follows: general scheme AND SO ON:

1. heating function.
2. Hot water supply.
3. Combination of two functions - heating and hot water supply (DHW).
4. Combination of hot water supply and warm ventilation.

Metering devices

On what principle does the item work?

The most common ITP connection scheme is an independent heating and independent closed DHW system. The principle of operation for an individual heat supply object consists in the following processes:

1. The supply pipeline supplies the point with a heat carrier, which, in turn, gives off heat energy to heaters and ventilation.
2. Further, the carrier rushes to the return pipeline, and then, for reuse, to the enterprise's main line, where primary thermal generation takes place.
3. What volume of coolant is consumed by consumption points to make up for heat losses.
4. Water (cold) from the water supply flows through the pump through the pipes. Then the part heats up and flows into the circulation DHW circuit, part is given to consumption points.
5. Hot water, circulating through the system, gradually heats up the containers (radiators, pipes), which give off heat.

Documents for Energy Supervision

In order for the admission to operation to be successfully carried out, the following package of papers is provided to the Energy Supervision Service:

• technical conditions, certificate on connection of the installation by the power supply organization;
• project, approvals;
• acts - responsibility, readiness of the system, acceptance of work performed, hidden work, flushing of the system, admission to safe operation;
• ITP passport;
• certificate of readiness of the item;
• a certificate stating that an agreement has been concluded with the energy supply company;
• a list of persons responsible for the maintenance and repair of the system;
• an order that a responsible person attached to the ITP has been appointed;
• certificate of a welding specialist (copy);
• quality certificates for components and elements;
• instructions for positions on ensuring fire and operational safety;
• instruction manual for the item;
• log of instrumentation, where orders, tolerances, defects, etc. are noted;
• order for connecting heating networks to ITP.

The qualifications of the maintenance personnel of the ITP must be mandatory, but its high level is not required. Therefore, all operators allowed to use and maintain the point are trained. During the shutdown of the water supply system, the pumps are not allowed to start. Pressure gauges should be monitored regularly, the pressure threshold should be monitored, adjusted according to the scheme and instructions. It is also extremely important to prevent overheating of electric motors, advanced level vibrations, noise. When closing the valves, it is not necessary to make excessive efforts; it is strictly forbidden to disassemble the regulators during a pressure surge. Before use, the system inside must be flushed.

BTP - Block heating point - 1var. - this is a compact thermomechanical installation of complete factory readiness, located (placed) in a block container, which is an all-metal load-bearing frame with sandwich panel fences.

ITP in a block container is used to connect heating, ventilation, hot water supply systems and technological heat-using installations of the whole building or part of it.

BTP - Block heating point - 2 var. It is manufactured in the factory and supplied for installation in the form of ready-made blocks. It may consist of one or more blocks. The equipment of the blocks is mounted very compactly, as a rule, on one frame. Usually used when you need to save space, in cramped conditions. By the nature and number of connected consumers, the BTP can refer to both ITP and CHP. Supply of ITP equipment according to the specification - heat exchangers, pumps, automation, shut-off and control valves, pipelines, etc. - Supplied in separate items.

BTP is a product of full factory readiness, which makes it possible to connect objects under reconstruction or newly built to heating networks in the shortest possible time. The compactness of the BTP helps to minimize the equipment placement area. Individual approach to the design and installation of block individual heat points allow us to take into account all the wishes of the client and translate them into a finished product. warranty for the BTP and all equipment from one manufacturer, one service partner for the entire BTP. ease of installation of the BTP at the installation site. Production and testing of BTP in the factory - quality. It is also worth noting that in case of mass, quarterly construction or volumetric reconstruction of heating points, the use of BTP is preferable compared to ITP. Since in this case it is necessary to mount a significant number of heating points in a short period of time. Such large-scale projects can be implemented in the shortest possible time using only standard factory-ready BTPs.

ITP (assembly) - the possibility of installation heating point in cramped conditions, there is no need to transport the complete heating unit. Transportation of individual components only. The equipment delivery time is much shorter than BTP. Cost is lower. - BTP - the need to transport the BTP to the installation site (transportation costs), the size of the openings for carrying the BTP impose restrictions on dimensions BTP. Delivery time from 4 weeks. Price.

ITP - a guarantee for various components of a heating point from different manufacturers; several different service partners for various equipment included in the heating substation; higher cost installation work, terms installation work, T. i.e. when installing an ITP, the individual characteristics of a particular room and the “creative” decisions of a particular contractor are taken into account, which, on the one hand, simplifies the organization of the process, and on the other hand, can reduce the quality. After all, a weld, a bend in a pipeline, etc., is much more difficult to perform qualitatively in a “place” than in a factory setting.
