STAND FOR RESEARCH OF PARAMETERS OF HOUSEHOLD HEAT PUMPS FUNCTIONING Russian patent published in 2018 - IPC F25B30/02 G01M15/02 F25B49/02 

FIELD: testing equipment.

SUBSTANCE: invention relates to stands for carrying out thermodynamic studies of the efficiency of heat pumps. Evaporator, the compressor, the condenser, the control valve, the heat exchanger-coolant cooler installed between the condenser and the control valve are arranged in series. External circuit with a capacity for a low-potential heat carrier is configured to control the temperature of a low-potential heat carrier. Internal circuit with a container for a high-potential heat carrier is configured to control the temperature of a high-potential heat carrier. In order to regulate the temperature of the refrigerant at the compressor inlet, the booth additionally contains a heat exchanger-superheater of the refrigerant installed between the evaporator and the compressor.

EFFECT: providing the possibility of regulating and controlling the parameters of the coolant both at the outlet of the condenser and at the exit from the evaporator of the heat pump in order to experimentally study the effect of these refrigerant parameters on the efficiency of the operation of domestic heat pumps.
