HEAT PUMP DEVICE, AND INSTALLATION FOR AIR CONDITIONING, WATER HEATER WITH HEAT PUMP, COOLING DEVICE, FREEZER, INCLUDING HEAT PUMP DEVICE Russian patent published in 2017 - IPC F25B1/00 F24F11/02 

FIELD: engines and pumps.

SUBSTANCE: heat pump device includes an inverter that applies a desired voltage to the motor of the compressor. Containing the inverter control unit which resets the interphase or phase voltages and phase currents having a frequency higher than the frequency during normal operation mode to perform driving with interlocking of the compressor motor. Recovery is based on the respective phase voltage and interphase or phase currents of the motor compressor during a plurality of cycles of RF excitation. This heat pump device may be used in an air conditioning apparatus, water heaters, refrigeration system or freezer.

EFFECT: prevent refrigerant stagnation and increasing the reliability and efficiency of the system.
