Abstract
In this paper, based on the regulation characteristics of electronic
expansion valve, an experimental platform is built for studying a vehicle
heat pump system. Under an ultra-low temperature condition of -10?C, the
influence of the super-heat setting value of the electronic expansion valve
on the main heating performance parameters of the system is analyzed. The
results show that when the superheat setting value of the main valve
increases from 2 K to 8 K, the discharge temperature of the compressor
increases, the heating capacity of the system decreases by 12.6%, and the
compressor power decreases by 15.9%. When the superheat setting value of
make-up valve increases from 15 K to 30 K, the discharge temperature of the
compressor increases, the heating capacity of the system decreases by
17.7%, and the compressor power decreases by 22.0%.
