HEAT PUMP Russian patent published in 2024 - IPC F25B30/02 F24T10/13 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering, in particular, to thermal plants used for heating and cooling of premises. Heat pump comprises compressor, heat exchanger-condenser, liquid separator, circulation pump and controller arranged and fixed in the housing. Liquid separator is equipped with a window to control the level of liquid freon. On one side the compressor is interconnected with the inlet of the heat exchanger-condenser, and on the other side it is interconnected with the liquid separator made with possibility of communication on the other side with the outputs of the geothermal probes. First outlet of the heat exchanger-condenser is interconnected with the inlet of the circulation pump, which in its turn is made with the possibility of interconnection with the heat carrier circuit of the heating system. Heat exchanger-condenser contains the second output intended for communication with inputs of geothermal probes through uncontrolled expansion valves. Heat exchanger-condenser contains the second input intended for communication by means of the return pipeline with the heating system heat carrier circuit. Controller is connected to compressor and circulation pump. Controller is configured to change the speed of the circulating pump if, when the pressure at the compressor outlet changes, the permissible level of liquid freon in the liquid separator remains, and in case the level of freon rises during pressure change, the circulation pump is stopped.

EFFECT: providing stable performance of the heat pump, reducing the risk of emergencies, simplifying the design.
