ROOMS HEATING AND HOT WATER SUPPLY HEAT PUMP SYSTEM Russian patent published in 2018 - IPC F24D15/00 

FIELD: motors and pumps.

SUBSTANCE: invention relates to heating systems with heat pumps using heat from the natural or artificial origin low-temperature sources to produce water suitable for the autonomous heating and hot water supply in residential buildings. Heat pump pant comprises heat pump including evaporator assembly, condenser assembly, compressor and expansion valve, as well as external horizontal ground loop with the ground heat exchanger, internal circuit with heating devices and solar collector with heat exchanger and hot water tank, and differs in that the external horizontal ground loop ground heat exchanger is made in the form of unit from the coaxially arranged pipes, through which liquid heat transfer media circulate, wherein the ground heat exchanger inner tubes are connected to the solar collector heat exchanger assembly, and the ground heat exchanger outer tubes are connected to the heat pump evaporator assembly.

EFFECT: increase in the compression type heat pump system efficiency, operating by the ground-water scheme for the rooms heating and hot water supply.
