Summary

Superheat of evaporator outlet is a symbol of state of air - conditioning. In order to study the effect of superheat on the performance of evaporator and system in automotive air - conditioning, a serial experiments have been done. A new kind of valve has been used to control the superheat in the standard automotive air - conditioning bench, and the effect of superheat on the performance has been studied. The results show, capacity of evaporator increases with the decrease of superheat, and it can reach 19.40% in the study' s system. COP increases to a maximum value then decreases with the decrease of superheat of evaporator outlet, and it can reach 17.8% in the studied system.
