ABSTRACT:
A refrigeration system comprising: a duct; a compressor having an inlet and an outlet; a reheat coil located in the duct and having an outlet and an inlet operatively connected to the compressor outlet; and a condenser having an outlet, and an inlet operatively connected to the reheat coil outlet. The system also comprises an expansion device, an evaporator and a receiver system. The expansion device has an outlet, and an inlet operatively connected to the condenser outlet. The evaporator is located in the duct upstream of the reheat coil and has an inlet operatively connected to the expansion device outlet, and has an outlet operatively connected to the compressor inlet. The receiver system has an inlet operatively connected to the condenser outlet and has an outlet operatively connected to the evaporator inlet. The receiver system includes an upstream flow control device, a receiver and a downstream flow control device in series.
