摘要
随着环境问题的加剧,制冷行业HCFCs制冷剂的替代受到普遍关注。新型环保制冷剂HFO-1234yf已在汽车空调中得到应用。主要从基本性质、燃烧性能、毒性、相容性及系统循环性能等方面介绍HFO-1234yf,并与R22替代制冷剂如R32、R290、R1270相比较,指出其替代R22的可行性,建议加强对HFO-1234yf在家用空调系统中替代R22的系列研究。
With the intensification of environmental problems, refrigeration industry has drawn great attention to alternative refrigerants to HCFCs . The new environment - friendly refrigerant HFO - 1234yf was applied in automotive air conditioning. In this paper, HFO- 1234yf was introduced by fundamental properties, flammability, toxicity, compatibility and system cycle performance. Compared with another alternative refrigerant R22 ,such as R32, R290, R1270, the possibility of HFO -1234yf of substituting for R22 was pointed out. It was recommended that more experimental study should be carried out on replacing R22 with HFO - 1234yf.
