摘要
针对容积式制冷压缩机性能试验中影响制冷量测量不确定度的各种因素,通过对小型全封闭活塞式压缩机的热力性能模拟,分析得出了压缩机排气压力对制冷量不确定度的影响关系。
The factors causing uncertainty of the performance tests of refrigerant compressors are analyzed. Thetransfer relation of uncertainty from the parameters measured to the results calculated is deduced. The effects on uncer-tainty of results and the treatment of factors such as discharge pressure are discussed based on the simulation of ahermetic reciprocating compressor.
