A refrigeration system including an evaporator. A reservoir is connected to the evaporator at a point intermediate the inlet and the outlet of the evaporator. The reservoir is placed in heat exchange relationship with the suction line near the outlet of the evaporator. In one embodiment a liquid level sensor is provided in the reservoir and the output of the sensor is used to control an expansion valve connected to the inlet of the evaporator. In another embodiment a capillary or fixed orifice device is used as an expansion device for the evaporator and the reservoir acts as a refrigerant storage device to accommodate various operating conditions of the refrigeration system.
