A control system for air conditioning apparatus, particularly well suited for automotive applications, includes a constant pressure regulating valve between the condenser and the evaporator and a superheat responsive valve between the evaporator and the compressor. The superheat responsive valve is responsive to the temperature of air within the controlled space; and the control mechanism may be adjusted by the operator to obtain any desired setting. This assures optimum comfort air conditioning under a variety of load and air flow conditions. The system is designed to prevent carryover of liquid refrigerant into the compressor and also avoids evaporator coil freeze-up.
