  • Patent number: 7043927
    Abstract: A transport refrigeration system, the transport refrigeration system including a container defining an enclosed volume and a refrigeration module coupled to the container. The refrigeration module is disposed to regulate the temperature of the enclosed volume and includes a compressor having a discharge port and a suction port, a condenser heat exchanger unit operatively coupled to the discharge port, an evaporator heat exchanger unit operatively coupled to the suction port, a condenser fan disposed proximate to the condenser heat exchanger unit, an evaporator fan disposed proximate to the evaporator heat exchanger unit; and a suction modulation valve coupled to the suction port. The transport refrigeration system further includes a bypass module coupled to the refrigeration module. The bypass module includes: a bypass mode switch having a normal operation position and bypass operation position; and an operational mode switch having a full cool position and fan only position.
