  • Method and apparatus for hybrid power trailer refrigeration
    Patent number: 11161388
    Abstract: A refrigeration system for cooling a refrigeration compartment. The refrigeration system comprises a cooling reservoir for cooling refrigerant in a first loop using energy recovered from an engine exhaust stream and a refrigeration circuit comprising a compressor drivable by an internal combustion motor, the compressor circulating refrigerant in a second loop. The refrigeration system comprises at least one heat exchanger in communication with the first and second loops to receive cooled refrigerant, and at least one blower for forcing air over the at least one heat exchanger. A controller selectively activates the internal combustion motor based on a temperature of the cooling reservoir.
    Type: Grant
