摘要
随着HCFCs禁用期的不断提前,R22替代工作正在全球范围内加快进程,找到一种既能保持R22原有优点,又具有较高的COP,且不会对大气臭氧层和温室效应产生影响的替代物已成迫在眉睫的任务。基于这一背景,对替代剂R410A进行了理论热力计算,并根据理论计算结果,分别对R22和R410A为制冷剂的制冷系统进行了详细的分析及比较,并得出相应的适用性的结论。
As HCFCs will be phased out more and more earlier, the substitution of R22 is quickened in the global range. To find an alternative for R22, with low global warming potential ,zero ODP and high cOP has been an urgent task. Against this background, thermodynamic calculation is done with R410A. According to the theoretical calculation detailed analysis and comparisons are made between the refrigeration systems that use R22 and R410A as refrigerant respectively.
