摘　　要：设计了一套混合制冷工质充注装置,该装置采用定容积储气罐,通过测量其温度和压力变化,根据工程热力学原理可以得到所充制冷工质的质量。针对充注过程进行了分析,对装置的结构和原理进行了讨论。运用两种方法计算本装置在环境温度下充注制冷工质的质量,并对两种计算结果进行了对比分析。A set of mixed refrigerant filling device was designed,in which a fixed-volume gas tank was used.By measuring the temperature and pressure change of fixed-volume gas tanks,the quality of refrigerant charge can be got according to engineering thermodynamics.The filling process was analyzed,the device structure and principle was discussed.The filling refrigerant quality in ambient temperature was calculated using two methods and the two calculation results were compared.
