Abstract:
A dual evaporator air conditioning system for use with a refrigerant for cooling air, said system comprising:a refrigerant circuit; a compressor in fluid communication with said refrigerant circuit for compressing and circulating the refrigerant; a condenser in fluid communication with said refrigerant circuit for condensing the refrigerant; a primary air conditioning unit operable between cooling and non-cooling modes and having a primary evaporator in fluid communication with said refrigerant circuit and a primary blower for moving the air across said primary evaporator in said cooling mode while discontinuing movement of the air across said primary evaporator in said non-cooling mode; an auxiliary air conditioning unit operable between cooling and non-cooling modes and having an auxiliary evaporator in fluid communication with said refrigerant circuit and an auxiliary blower for moving the air across said auxiliary evaporator in said cooling mode while discontinuing movement of the air across said auxiliary evaporator in said non-cooling mode; and a heat exchanger for warming the refrigerant in said auxiliary evaporator when said primary air conditioning unit is in said cooling mode while said auxiliary air conditioning unit is in said non-cooling mode to prevent accumulation of liquid refrigerant in said auxiliary evaporator.
