Abstract
In order to investigate the effect of thermal expansion valve (TXV) on the characteristics of air conditioning system in fast train, the TXV static superheat regulation experiment was carried out in one failure air conditioning system of the fast train. During the experiment, the characteristics of air conditioning system were analyzed under different TXV static superheat conditions. The results showed that static superheat increasing can efficiently improve the TXV refrigerant shortage and the refrigerant non-uniform distribution in evaporator, and then increase the evaporator pressure and temperature to solve the problem of insufficient cooling capacity.关键词
