Abstract
A cascade refrigeration system is provided. The cascade refrigeration system includes a low stage having a first refrigerant flowing therethrough and a high stage having a second refrigerant flowing therethrough. The low stage includes a compressor and evaporator coils. The input of the evaporator coils is operatively connected to the output of the compressor by an input conduit and the output of the operator unit is operatively connected to the input of the compressor by an output conduit. A bypass line has an input in communication with the input conduit and an output in combination with the output conduit. A bypass heat exchanger effectuates the heat exchange relationship between the first refrigerant flowing through the bypass line and the first refrigerant flowing through the input conduit.
