HEAT GENERATOR Russian patent published in 2022 - IPC F24D17/02 F25B25/02 F25B30/00 F25B27/02 

FIELD: heat engineering.

SUBSTANCE: invention relates to the field of heat pump installations used to convert low-grade heat in heating and hot water supply systems. Connected in series, the compressor of the steam compression heat pump, the condenser of the electrically driven heat pump, the throttle valve of the electrically driven heat pump, the evaporator of the electrically driven heat pump form a circuit of the electrically driven heat pump filled with refrigerant. The heat engine is connected to the compressor of the electrically driven heat pump through the shaft. Connected in series, the steam generator of the absorption heat pump, the condenser of the absorption heat pump, the throttle valve of the absorption heat pump, the evaporator of the absorption heat pump, the absorber of the absorption heat pump filled with absorbent, the circulation pump of the absorption heat pump, the expansion valve of the absorption heat pump form the circuit of the absorption heat pump filled with refrigerant and absorbent. The expansion valve of the absorption heat pump is located between the absorber of the absorption heat pump and the steam generator and is connected in parallel to the circulation pump of the absorption heat pump. The heat engine is connected to the steam generator of the absorption heat pump by the cooling circuit of the heat engine. The condenser of the electrically driven heat pump is connected in series to the condenser of the absorption heat pump and to the heat exchanger of the exhaust gases forming the circuit of the heat supply system.

EFFECT: joint use of fuel energy and renewable low-potential energy of the environment for the efficient production of heat.
