ABSTRACT:
A refrigerator has a machinery compartment at the bottom for housing a motor-compressor unit and a condenser and has an air inlet opening at the front thereof extending substantially across the width of the compartment. The machinery compartment includes a forward section for receiving the condenser and a duct at the rear portion thereof for receiving the motor-compressor unit. The duct has an air inlet at one end for receiving air from the forward section. The condenser extends generally horizontally from one side wall of the compartment across a substantial portion of the forward section. A drain pan is supported above the condenser for collecting water draining from the interior of the refrigerator. The drain pan additionally functions as a baffle to cause air entering the forward section to flow effectively over the condenser. A fan is positioned at the inlet of the duct and the motor-compressor unit is so positioned in the duct that the compressor portion thereof is positioned adjacent to the fan so that substantially all of the air discharged from the fan is directed onto the compressor portion, thereby maximizing the heat transferred from the compressor to the air flowing through the compartment.
