Vapor injection technology for heat-pump air conditioner of electric bus in an extreme environment
نویسندگان
چکیده
In order to solve the problems of a heat pump air conditioner for an electric bus under extreme conditions, such as large compression ratio, high discharge temperature, reduced system performance, frequent shutdown compressor due overheat protection, this paper proposes vapor injection technology with economizer, and carries out theoretical analysis process reveal effect on performance conditioner. The results show that at ultra-low temperature heating operating when speed increases from 2000 rpm 5000 rpm, capacity 16.2% 22.7%, coefficient 2.8% 14.2%.

As global warming has raised more critical concerns in recent years, refrigerants with high global warming potentials (GWP) are facing the challenges of being phased out. R410A, with a GWP of 2,088, has been widely used in residential air-conditioning and heat pump systems. A potential substitute for R410A is R32, which has a GWP of 675. This paper investigates the performance difference of R41...
