    Abstract: In the preferred form, a refrigerator cabinet is provided with a sheet metal outer shell and a plastic inner liner with polyurethane foam insulation in between. The interior of the inner liner is divided into an upper freezing compartment and a lower above freezing compartment by a sheet metal wall having a lower portion in the rear and a higher portion in the front. Above this lower portion there is provided cast foam insulation beneath an evaporator compartment having inlets extending to it from the front of the upper freezing compartment and from the lower compartment through the portion of the sheet metal wall between the lower and higher portions. Resting upon the cast foam insulation is a large drain pan which extends beneath and supports a tubular horizontally extending evaporator having upright fins extending from the front to the rear. The drain pan also has brackets and a vibration-absorbing mounting for supporting the fan motor at the rear of the evaporator having a drive shaft extending rearwardly through the rear wall of the inner liner where it is provided with a side inlet centrifugal fan which draws the air through the inlets and the evaporator and discharges it into an upwardly extending duct extending to the upper compartment and a downwardly extending duct extending to the lower compartment, both of which are housed in the plastic foam insulation between the rear walls of the inner liner and outer shell.
