Block Individual Heat Point (BITP) - In its composition, it is intended to combine many products manufactured by both our republics and other enterprises of our republic, incl. Plastic heat exchangers, locking valves, automatic control and dispatching systems, etc. The bit is a factory readiness heat dissipation equipment unit for connecting the consumer to the thermal network.
The main components of the thermal point are heating heat exchangers, hot water supply (DHW) and, if necessary, ventilation. Specialists of our company have developed 12 options for typical circuit solutions of the BITP device for various loads. Since the heat point is ready for connection and operation by the unit, it includes, in addition to heat exchangers, the following main equipment:
Advantages of applying individual thermal items:

Payment
From the point of view of minimizing energy consumption in central heating networks, the flow regulation and heat accounting is advisable to implement in individual thermal points, for each consumer separately. The use of ITP systems has a number of advantages compared to the CTP. It allows us to take into account the individual features of each consumer, which reduces the consumption of thermal energy and creates the most comfortable conditions for the consumer.
Heating, which already exists, new objects, residential buildings and so on. In addition to the supply of heating, the delivery of hot water is also possible and the attachment of the object to such communication as sewage.
Block (BTP) is ready-to-work installed installation. It is important to know here that the layout of any devices for each item is individually carried out. The main characteristic on which specialists are based on assembling the unit are the size of the room in which the object will be installed.
Same production blockpoint It is carried out through the use of basic schemes, on the basis of which, it is possible to attach this equipment to the usual engineering thermal network of the building. There is a general program for calculating the Danfoss for thermal points. It is worth noting that this is one of the rather large manufacturers of block thermal points.
If we talk about the most common configuration of the BTP, which is considered standard, then it includes such elements as:
Block thermal item is an automated installation that is intended to transmit energy from the boiler room, thermal power plant, RTS to heating, as well as ventilation and GVS communications connected to the residential or production buildings. In other words, this is a local mediator between the station and the consumer.
If we talk about the room in which it is planned to install a block heat point, it should be sufficient in size so that all block equipment can be placed, as well as the control and measuring instruments necessary for the functioning of the system. All these devices are needed to ensure that the TP can perform features such as:
In its characteristics and reception of heat sources, TP are divided into species. The first view refers to open system. In this case, the fluid comes to the BTP directly from the coolant, and the entire volume of the fluid that goes to the operation of the equipment is replenished due to the full or partial fence of water.
In its type of connection to the system open species BTP can be divided into two groups:
Installing an automated block thermal point can give a system of several following advantages:
The acquisition of block TPs in such major producers has its advantages. For example, one of the main differences from other manufacturers is that the equipment is supplied to the installation site in the ready-made form. That is, collecting the unit does not have to have, which significantly increases the installation speed and connection. Of these advantages, it is also possible to allocate that the installations from Danfoss can be operated in fully automatic mode.
In order for the equipment to work in this mode, you just need to set the desired temperature and pressure values. Adjusting and controlling devices will continue to support the specified mode of operation. It is also worth adding that there is an opportunity for an individual configuration on the buyer's order. You can add the accounting system, the system of remote control of the device, etc.
This paper is a document on which the processing of the thermal point is carried out. All rules that are spelled out in this paper are applied to such TPs whose characteristics fall under specified: the pressure of hot water to 2.5 MPa, the fluid temperature is up to 200 degrees Celsius. If the installation works with steam, then its conditional operating pressure should be within up to 6.3 MPa, and the temperature should not exceed 440 degrees Celsius.
According to this joint venture, thermal points are divided into two main categories - these are individual or central. Individual TPs are designed to join the heating system, water supply and ventilation of one building or its part. The central TPs are intended for the same as the ITP, but with one difference that they are used for several buildings immediately.
The manufacture of individual thermal items Etra is carried out on the basis of design documentation developed by typical schemes and taking into account the individual needs and conditions of the customer.
