不完全湿压缩应用于转子式制冷系统的可行性研究
|
摘要
针对部分制冷工质排气温度较高的现象,将不完全湿压缩方法应用于转子式制冷系统,通过在不同频率下改变压缩机的吸气状态(过热至不完全湿压缩),研究了系统循环性能及核心部件的热力特性。实验结果表明:不完全湿压缩下存在一个最佳干度控制范围0 Aiming at the phenomenon that the exhaust temperature of some refrigerants is high,the incomplete wet compression method is applied to the rotor refrigeration system.By changing the suction state(superheating to incomplete wet compression) of the compressor at different frequencies,the cycle performance of the system and the thermodynamic characteristics of the core components are studied.The experimental results show that there is an optimal range of quality under incomplete wet compression 0
