METHOD FOR OPERATION OF AN OPEN HEAT SUPPLY SYSTEM Russian patent published in 2022 - IPC F24D3/00 F24D3/08 F24D3/18 

FIELD: heat power engineering.

SUBSTANCE: method for operation of an open heat supply system, whereby mains water is prepared at the TPP and directed to the pipelines of heating and hot water supply systems of consumers via the supply pipeline of the heating network through the heat point. The temperature of the mains water in the supply pipeline of the heating network is adjusted at the TPP depending on the temperature of the outside air according to the central quality adjustment schedule without a lower break in the temperature schedule. The mains water returned from the consumers is directed to the TPP via the return pipeline of the heating network. The mains water directed for hot water supply is heated to the required temperature in a heat pump, the condenser whereof is connected by the heated medium to the pipeline of the hot water supply system, and the evaporator is connected by the heating medium to the return pipeline of the heating network. The water for hot water supply is only collected from the return pipeline of the heating network. The productivity of the heat pump is adjusted by changing the flow rate of the mains water supplied to the evaporator depending on the temperature of the hot water after the condenser of the heat pump.

EFFECT: increase in the efficiency of operation of an open heat supply system due to the reduction in the flow rate of mains water from the supply pipeline and increase in the duration of operation of the heat pump, increase in the specific heat-end production of electric power at the TPP due to the additional cooling of mains water in the return pipeline of the heat network.
