Description

 The invention relates to heating equipment and can be used in multi-storey residential buildings with apartment heat metering.

 Known apartment water heating system with pump circulation, containing a boiler, pump, heaters and an expansion vessel (Handbook plumbing. Kiev: Budivelnik, 1975. P. 197, Fig. 60).

 The well-known apartment system is intended only for heating residential buildings of low-rise buildings.

 Known subscriber input of a heat supply system containing a supply and return pipelines connected to a heating network, and a water heating system. A regulator is installed on the supply pipe connected to a temperature sensor mounted on a heat pipe (A.S. 672448, F 24 D 3/00, 1981, USSR).

 The well-known subscriber input does not provide for providing the building with hot water, and there are no meters for accounting for thermal energy in it.

 The closest technical solution to the proposed system is an apartment heating and hot water supply system containing a boiler with automatic control, a hot water supply heat exchanger, room and atmosphere temperature sensors, a four-way control and mixing valve (Yu.S. Davydov, S.V. Nefelov. New Automation Systems for Heating Devices, Moscow: Stroyizdat, 1990, p. 138, Fig. 47).

 The well-known combined apartment heating and hot water supply system is intended only for cottages in which heat energy metering is optional.

 The drawing shows a schematic diagram of an apartment system with meters for controlling and regulating the supply of thermal energy.

 The heating and hot water supply system installed in the apartment of a multi-storey residential building has internal and external fences of apartments 1 and 2, through which the supply (direct) and return pipelines 3 and 4 are laid, having shut-off devices 5, as well as a heat pipe 6, the lower end 7 which is mounted in the return pipe 4, and the upper end 8 is brought out through the outer fence of the apartment 2. Apartment pipelines 3 and 4 through the heat meter 9, locking devices 5 and locking devices 10, placed in a metal lockable box 11 on the landing, connected to the risers 12 and 13 of the heating network, located at the entrance of the building. The heating system includes heaters 14, an air collector 15 and shut-off valves 16 and 17. The heat exchanger 18 of the hot water supply system has a coil 19 connected to the supply pipe 3 through the valve 20, and hot and cold water pipelines 21 and 22. A regulator is installed on the supply pipe 3. 23, connected by an electric impulse line 24 with a temperature sensor 25 mounted on the heat pipe 6, and a temperature sensor 26 installed in the apartment building.

 The risers 12 and 13 of the heating network are located at the entrance of the building, and the locking devices 10 are located on the landing in box 11, they are managed by the heat supply organization. Locking devices 5 are in the apartment, they are disposed of by the tenant. The controller 23 (control valve) has a bypass pipe (not shown), for the summer it is disconnected from the pulse line 24.

 Apartments above and below the floor also have locking devices 10 located in boxes 11.

 The apartment heating and hot water supply system operates as follows.

 The representative of the heat supplying organization makes sure that the apartment heating system and hot water supply are in good condition by a test run of heat in the apartment, opens the shut-off devices 10. If there is no leak in the heating system, he closes the box 11 with a key and seals it. The tenant at the beginning of the heating period opens the shut-off devices 5, valves 16 and 17, releases air from the air collector 15, closes the valve on the bypass pipe (not shown), thereby activating the regulator 23 in operation. By setting the required room temperature on the setpoint controller (not shown), the tenant monitors the operation of the heat meter 9. Automatic devices 23, 24, 25, and 26 provide a constant apartment room temperature with correction for changes in the outside air temperature, perceived by the heat pipe 6.

 If there is a need for hot water, the tenant switches on the heat exchanger 18: it opens the cold water inlet and the hot water outlet, opens the valve 20, closes the valve 16 and the valve at the water outlet from the heat exchanger 18 (not shown). When the water in the heat exchanger 18 is heated to the required temperature, it opens a valve at the outlet of it and begins to disassemble hot water for household needs. When the demand for hot water ceases, the valve 20 closes, and the valve 16 opens, the valve at the outlet of the heat exchanger 18 closes.

 For the summer period, the heating system is turned off by closing the valves 16 and 17 and opening the valve on the bypass pipe of the regulator 23.

 The use of a combined heating system and hot water supply reduces the consumption of pipes, provides the ability to disable, enable this or that system in the work if necessary by the consumer. The location of the locking devices 5 in the apartment allows the tenant to regulate the flow of the body.
