ABSTRACT:
A compact refrigeration heat exchanger comprising coiled tubing wrapped around a cylindrical chamber having input and output ports for preheating the evaporatior output to superheat liquid refrigerant prior to the compressor inlet by passing hot gas from the compressor output back through the coil while low pressure refrigerant flows through the chamber. The heat exchanger enables a refrigeration system to be defrosted without liquid refrigerant flood back to the compressor. Any liquid remaining accumulates in the heat exchanger due to the different lengths of the tubing in the heat exchanger.
