ABSTRACT:
A method is provided for operating a refrigerant vapor compression system at substantially zero cooling capacity to facilitate tight temperature control within a climate-controlled environment associated with the refrigerant vapor compression system. The method includes the step of diverting substantially all refrigerant flow from the primary refrigerant flow circuit of the refrigerant vapor compression system at a first location downstream, with respect to refrigerant flow, of the heat rejection heat exchanger and upstream, with respect to refrigerant flow, of the evaporator refrigerant expansion device to reenter the primary refrigerant flow circuit at a second location downstream, with respect to refrigerant flow, of the evaporator and upstream, with respect to refrigerant flow, of the compression device.
