ABSTRACT:
A refrigerant flow control unit for a refrigeration system, particularly a refrigeration system having a compressor, a condenser connected to receive refrigerant discharged from the compressor, and a plurality of evaporators. A first one of the evaporators is connected to receive at least a portion of the refrigerant discharged from the condenser and the remaining evaporators are connected to receive at least a portion of the refrigerant discharged from another evaporator. The refrigerant flow control unit is connected to receive at least a portion of the refrigerant discharged from each one of the evaporators. The refrigerant flow control unit is also connected to the compressor and is repeatedly operable to alternately connect one of the evaporators respectively in exclusive refrigerant flow relationship with the compressor. In one preferred embodiment, the refrigerant flow control unit is operated in accordance with measurable physical attributes of one or more of the evaporators, such as pressure, temperature, density of mass flow rate.
