摘要
R134a制冷剂的GWP值较高,即将被淘汰,但采用何种制冷剂来替代R134a却还未明确。鉴于此,提出将氨这种天然制冷剂应用到电动汽车空调上,作为R134a的替代制冷剂,并对研究设计的氨工质电动汽车空调系统做了性能研究,研究表明:氨工质电动汽车空调系统理论COP随蒸发温度、过冷度的升高而增大,随冷凝温度、过热度的升高而降低;研究设计的氨工质电动汽车空调系统理论COP为4.09,与R1234yf理论COP相当,但经二次回路设计后氨比R1234yf安全可靠;相较于R152a,氨的GWP值更低,环保性更好;相较于CO2,氨的COP更高,节能性更好。
The GWP value of R134 a refrigerant is high, will be eliminated in the near future, but adopt what kind of refrigerant to replace R134 a is not yet clear. In view of this, this paper put forward using ammonia as alternative refrigerant of R134 a, and applied to the electric vehicle air conditioning system. At the same time, made a performance research for ammonia working medium electric vehicle air conditioning system, through study, found that： The theoretical COP of ammonia working medium electric vehicle air conditioning system increases with the increase of evaporation temperature and super cooling degree, decreases with the increase of condensation temperature and superheat degree, the theoretical COP of ammonia working medium electric vehicle air conditioning system is 4.09, which is equivalent to the R1234 yf theory COP, but Ammonia is more safe and reliable than R1234 yf after two times of circuit design; compared to R152 a, ammonia GWP is lower, has a better environmental performance; compared to CO2, ammonia COP is higher, energy saving is better.
