A refrigeration system generally including a compressor, a condenser, an expansion device, and an evaporator. A refrigerant expansion tank is connected to the suction side of the compressor to vary the charge of refrigerant in the refrigeration system. Preferably, the expansion tank adds additional refrigerant to the system only after it has reached, is near, or at least is approaching, its operating point. The additional refrigerant is removed from the refrigerant fluid path and contained within the expansion tank when the refrigeration system is turned off.
