Abstract
A refrigeration system includes a refrigerated cavity, a first compression system, and a second compression system. The refrigeration system further includes a controller configured to operate the refrigeration system in a first mode in which the first compression system and the second compression system operate to cool the refrigerated cavity. The refrigeration system is further configured to selectively operate the refrigeration system in a second mode in which a refrigerant discharged from the second compressor is routed through the first evaporator to defrost the first evaporator.
