摘要
本文通过理论热力学分析和实验研究对喷气增焓技术在定频定容压缩机的应用进行了探索,研究了不同制冷剂在定频喷气增焓系统中的能力和能效的提升效果,得到R410A和R32系统的制热量都大于R22和R290系统的制热量,最后利用R410A系统进行了理论和实际测试数据进行了对比,得到理论和实际的最大预测误差为8.7%,平均预测误差为5.5%;实际测试能力提升最大提升幅度达到19.3%,整体平均提升制热量13.4%。
This paper explores the application of jet enthalpy-increasing technology in constant-frequency and constant-volume compressor through theoretical thermodynamic analysis and experimental research, and studies the enhancement effect of different refrigerants in constant-frequency and constant-volume compressor system which indicates that the heat production of R410 A and R32 is greater than that of R22 and R290. Finally, the theoretical and practical test data are compared by using R410 A system which reveals that the theoretical and practical maximum prediction error is 8.7 %, the average prediction error is 5.5 %; the maximum increase of capacity is 19.3 %, and the overall average increase of heat production is 13.4 %.
