A well-known scheme of an automated elevator heating station | Patent of Ukraine Mo 13928 A

OA IPC Eg240 19/10 Mo 95052382; Application 16.05.95; Publ. 25.04.97), which contains supply and return pipelines of the heat network, supply and return pipelines of the heating system, an elevator that is connected to the supply pipelines of the heat network and the heating system and is connected to the return pipelines of the heat network and the heating system using a mixing unit, a two-position regulator consumption of the heat carrier, which is installed on the supply or return pipelines of the heating system.

The disadvantage of the known design is the use of a prohibited circuit based on the elevator. According to clause 6.1.8 DBN V.2.5-67:2013 "Heating, ventilation for air conditioning", it is not allowed to connect a water heating and/or internal heat supply system to a centralized heat supply system using a hydraulic lift, including a regulated hydraulic lift.

The closest thing to the claimed invention is an individual heat point Patent of Ukraine for a utility model Mo 17972 0, IPC EG240 15/00; Application 05/03/2006; Publ. 16.10.2006), containing hot water supply pipes and return water drainage pipes, on which non-return valves are installed to prevent backflow of water. A filter, a heat and water meter, a regulator and a water mixing unit are installed in series on the supply pipe. A pressure regulator, a heat and water meter and a filter are installed on the return pipe of the heating network. In addition, a pressure switch is installed on the supply and return pipes of the heating system; a mesh filter is installed on the return pipeline of the heating system before the mixing unit.

Supply and return pipelines, on which pipe fittings, measuring and regulating devices, a mixing unit and a circulation pump are installed, ensure the functioning of the heating system.

Installation of a saddle two-way control valve with an electric drive and a control unit on the supply pipeline of the heating network ensures the maintenance of the required temperature of the heat carrier of the heating system and will allow efficient consumption of the thermal energy of the building.

З Equipping the supply pipeline of the heating system with a circulation pump with a pressure sensor-relay ensures the circulation of the heat carrier in the internal heating system and maintains the hydraulic mode of the building.

A mesh filter installed on the return pipeline of the heating system maintains the quality of the coolant and extends the service life of the equipment.

The drawing shows the scheme of the framework for controlling the heat consumption of the house during the transition from the elevator nodes to the heating system with forced circulation of the coolant.

The framework for controlling the heat consumption of the house contains the supply and return pipelines of the heat network, on which the shut-off valve (1), mesh filter (2), temperature regulator (3) with an electric drive (4) are installed. A shut-off valve (1), a strainer (2), a circulation pump (b), a pressure sensor-relay (7), coolant temperature sensors (9) are installed on the supply and return pipelines of the heating system. In addition, the frame contains a non-return valve (5), outdoor air temperature sensors (8), control unit (10), drain valves (11), thermometers (12), pressure gauges (13).

The device works as follows:

Hot water from the heating network passes through the supply pipeline, ball valve (1) and mesh filter (2), saddle two-way regulating valve (3). Next, through the non-return valve (5), the circulation pump (b) and the shut-off valve, the water enters the heating system, providing the necessary temperature in the building. The pump has a system of protection against "dry" running, overheating of the engine and protection against distortion of phase voltages with the help of a pressure sensor-relay (7).

Regulation of heat consumption is provided by the control unit (10), which, based on the signal of the outdoor air temperature sensor (8), determines the required temperature of the coolant at the entrance to the heating system, compares it with the actual temperature measured by the temperature sensor (9), and issues a control signal to the electric drive control valve, while changing the flow of coolant from the heating network.

In order to maintain the required quality of the coolant and extend the life of the regulator and circulation pump, the heat consumption control frame of the house is equipped with mesh filters (2). A shut-off valve (1) is provided for the possibility of disconnecting the frame during the non-heating period and carrying out routine work. Drain taps (11) are installed to drain the coolant.

Control of the operation of the energy-efficient framework for controlling the heat consumption of the house is carried out with the help of the control unit (10) and additional analog control and measuring devices - bimetallic thermometers (12) and manometers (13).

The framework for managing the heat consumption of the house can be used mainly in buildings connected to the heat network according to the dependent connection scheme for replacing the elevator unit.
