| 摘 要： | 介绍了以 Ｒ５００代替 Ｒ１２作制冷剂的冰箱的热工性能试验情况，分别给出了有关制冰能力、冷却速度与耗电量等方面的对比结果，用红外热像仪拍摄了冷凝器的对比温度分布，最后还对 Ｒ５００的合适灌注量及启动性能进行了探讨。试验结果表明，作为一种过渡性措施，采用Ｒ５００代替Ｒ１２是可能的，冰箱的系统、部件以及滑油等均无需作大幅改动，而且制冰能力和冷却速度还可加大加快，耗电量还略降低，ＣＯＰ有所提高。

| Abstract: | This article introduces the experimental research on the performance of refrigerator using R500 as an interim alternative refrigerant to R12. Some results of comparing experiments of refrigerators using R500 or R12 as refrigerant in freezing capacity, refrigerating speed, electricity consumption are given. In addition, the change processes of surface temperature of condenser used separately refrigerant R500 and R12 are measured by infrared thermovision. The optimum charging quantity and start performance of refrigerators with R500 have been studied also. The results show that R500 is an acceptable interim alternative refrigerant to R12. Not modifying the existing refrigerator system and lubrication oil, we can gain greater freezing capacity, faster refrigerating speed, higher COP and almost the same electricity consumption. |
