摘要(Abstract):

建立了基于电机效率随负载、频率变化和高低压侧、环境、电机之间换热的滚动转子式压缩机热力学稳态仿真模型,且与试验有较好吻合,进而对比研究了基于传统制冷剂R22和替代制冷剂R32、R290、R410A和R407C的滚动转子式压缩机。在一定工况范围内,分析了蒸发温度、冷凝温度对压缩机的性能影响。在相同的理论容积输气量、吸气过热度和工况下的对比研究表明:R32质量流量略大于R22而R290的最小;功率、排气温度、制冷量最大的是R32而最小的是R290,R32排气温度相比R22增加9.0~33.5℃,R290制冷量相比R22降幅13.1%~18.9%;R32的性能系数COP相比R22降幅0.2%~4.3%,R290的COP相比R22降幅2.0%~7.3%但相比R410A增幅0.2%~8.5%。
Thermodynamic steady simulation model of rotary compressor based on electric motor efficiency changing with load and frequency and heat exchange between high and low pressure sides,environment and electric motor is established.The simulation model agrees well with experiment.Rotary compressor based on traditional refrigerant R22 and alternative refrigerants R32,R290,R410 A and R407 C is compared and studied further.Within a certain range of operating condition,the influence of evaporation temperature and condensation temperature on the performance parameters of compressor is analyzed.In the case of the same theoretical volumetric displacement,suction superheat and operating condition,comparative study results show that mass flow rate of R32 is slightly larger than that of R22,mass flow rate of R290 is least;power,discharge temperature and refrigerating capacity of R32 is largest and those of R290 is least;discharge temperature of R32 is averagely 9.0~33.5℃ larger than that of R22,refrigerating capacity of R290 is averagely 13.1%~18.9% less than that of R22;COP of R32 is 0.2%~4.3% less the that of R22,COP of R290 is 2.0%~7.3% less than that of R32 but 0.2%~8.5% larger than that of R410 A.
