Abstract

A prototype refrigerator/freezer was fitted with a single evaporator, ducted so it could serve both compartments in a sequential manner. Two capillary tubes, one optimized for each compartment were attached to the suction line and controlled by a solenoid valve. A two-speed compressor operated at 3600 rpm in freezer mode and 2400 rpm when serving the food compartment. A variable speed fan was used to explore the response of the evaporator. The experimental results confirmed earlier simulation analyses, which predicted that achieving maximum energy savings (approx. 15%) would require a two-speed compressor having a high/low speed ratio of 5.
