A compact refrigeration unit for use in a trailer container that includes a support frame that is mounted upon the front wall of the container. A power package containing a diesel engine coupled to a generator and an electrically driven compressor are mounted in the lower section of the frame. Front and rear compartments are situated in the upper section of the frame. The front compartment contains a condenser heat exchanger and a pair of fan units are mounted in the bottom of the front compartment for directing condenser cooling air over the power package and the compressor. An evaporator heat exchanger is mounted in the rear compartment along with a pair of fan units mounted in the top of the compartment. The evaporator heat exchanger and the associated fan units communicate with the container to circulate conditioned air through the container.
