HEAT SOURCE Russian patent published in 2020 - IPC F25B30/06 F24D15/04 

FIELD: heat supply.

SUBSTANCE: invention relates to heat supply and can be used to produce heat energy based on heat pump without consumption of electric energy. Heat source includes heat pump and hydraulic ram. Heat pump comprises in-series connected capacitor, throttle and evaporator. Hydraulic ram comprises a feed pipe with an impact valve installed at its outlet and an air cap attached thereto, impeller, which includes a hollow housing, in the cross-section of which there is an elastic diaphragm dividing it into two isolated cavities and check valves of inlet and outlet of pumped medium, which are in series connected to the first cavity. Second cavity is connected to external pipeline, return spring is installed between elastic diaphragm and hollow case. Pump air pump with check valves of inlet and outlet of forced medium is connected to heat pump circuit between condenser and evaporator. External pipeline is connected to hydraulic ram tube. External circuit of the heat pump evaporator is connected in series to the feeding pipe of the hydraulic ram.

EFFECT: invention completely eliminates the need to consume electric energy, which together with intensification of heat exchange in the evaporator of the heat pump increases its overall energy efficiency.
