摘要
对设计的涡流管膨胀降压的R290制冷系统进行热力计算,并与常规节流降压R290制冷系统的性能比较,得出涡流管膨胀降压的R290制冷系统的性能系数,随着涡流管喷嘴效率的升高、蒸发温度升高和冷凝温度降低而增大。涡流管膨胀降压R290制冷系统的性能系数要明显大于常规制冷系统的性能系数,蒸发温度升高差值增大。涡流管膨胀降压R290制冷系统的性能系数提升随蒸发温度的升高、涡流管喷嘴效率的提高和冷凝温度的降低而相应增大。
The R290 refrigeration system with vortex tube expansion reduction pressure is designed.The performances of this R290 refrigeration system with vortex tube expansion reduction pressure are analyzed and compared with that of the R290 refrigeration system of throttle at the same running condition.The following conclusions are obtained.The coefficient of performances of the R290 refrigeration system with vortex tube expansion reduction pressure increase with the increasing of evaporation temperature,the decreasing of condensation temperature and the increasing of nozzle efficiency.The coefficient of performances of the R290 refrigeration system with vortex tube expansion reduction pressure is significantly greater than that of the R290 refrigeration system of throttle and the difference of the coefficient of performances between two refrigeration system increases with the increasing of evaporation temperature.The enhance value of the coefficient of performances of the R290 refrigeration system with vortex tube expansion reduction pressure increase accordingly with the increasing of evaporation temperature,the decreasing of condensation temperature and the increasing of nozzle efficiency.
