Influence of opening degree of electronic expansion valve on performance of R32 water source heat pump
The performance of a variable refrigerant flow type of rotor water source heat pump was experimentally investigated at different compressor frequencies (from 40 to 60 Hz) andopenings of the electronic expansion valve (from 6% to 60%). As the suction of the compressor changed from an overheated state...

| Summary: | The performance of a variable refrigerant flow type of rotor water source heat pump was experimentally investigated at different compressor frequencies (from 40 to 60 Hz) andopenings of the electronic expansion valve (from 6% to 60%). As the suction of the compressor changed from an overheated state to a gas-liquid state, the adjustment range of the opening of the electronic expansion valve decreased first and then increased. As the opening of the expansion valve increased, the compressionratio of the system continuously decreased.Furthermore, when the suctiongas contained a small amount of liquid (0.98 |
