摘　　要：在相同的条件下,理论分析了3～8℃出口过冷时R22和R410a冷凝器的换热量,结果显示:R410a冷凝器的换热量比R22冷凝器大约2%～4%。在换热器专用测试平台上开展了使用R22和R410a制冷剂的平行流冷凝器性能对比试验,结果表明:在制冷剂进口温度、压力及出口过冷度相同时,R410a平行流冷凝器的换热量略大于R22平行流冷凝器,与理论分析趋势一致。同时还发现使用R410a平行流冷凝器的流阻略小于使用R22的平行流冷凝器。Under the same conditions, analyze R22 and R410a heat exchange capacity under 3-8 ℃subcooling de- gree, the results show that： the heat transfer ratio of heat exchanger using R410a is 2% to 4%.higher than that using R22. Carry out the parallel flow condenser performance comparison test of using R22 and R410a on the heat exchanger test device. The results show that： at the refrigerant inlet temperature, pressure, and the same subcooling degree.The capacity of parallel flow condenser using R410a is slightly larger than that using R22, consistent with the theoretical trends; also find the con- denser flow resistance using R410a is slightly smaller than that using R22.
