ABSTRACT:
This application concerns an automobile air conditioning system having two evaporators and one compressor which is alternately activated and deactivated to prevent frost from accumulating on one of the evaporators by way of a refrigerant pressure responsive switch at the outlet of the one evaporator. A one-way check valve is located near the switch and between the evaporators to prevent reverse flowing of refrigerant from the one evaporator to the other evaporator.
