Summary:

Optimization of vehicle air conditioning performance at various drive cycles and ambient conditions can be achieved by regulating and distributing the refrigerant flow entering evaporators. Thermostatic expansion valve (TXV), as a flow control device, has been a key element in improving vehicle A/C system operating efficiency and maximizing cooling capacity. Three scenarios are addressed in this paper: (a) the selection of TXVs for a sports utility vehicle (SUV) climate control system, in which a front HVAC unit and an auxiliary HVAC unit are installed; (b) the methodology of developing a goal-oriented criterion for identifying the TXV combination to fulfill the optimization of A/C system performance; and (c) the analytical and experimental evaluation of vehicle cooling performance by varying TXV combinations in various vehicle operating modes
