| Summary: | Incomplete wet compression can sharply reduce the discharge temperature of compressors. However, the challenge of the application is how to control the real-time suction refrigerant quality of compressor within the appropriate range. A method using quasi saturation isentropic compression discharge temperature (QSICDT) to control suction refrigerant quality of compressor was proposed in the paper. The performance change of refrigeration system with R22, R32, R134a and R410A is theoretically analyzed under AHRI (air-conditioning heating and refrigeration institute) air conditioning and refrigeration applications when this method is used to control the suction refrigerant with a small liquid, and the method is verified by R32 experimental data. The results show that using QSICDT can control compressor suction with a small amount of liquid refrigerant; the capacity and COP all can reach the maximum for wet compression refrigeration system with R32 by using QSICDT to control suction refrigerant quality at 0.96 to 1. |
