Abstract
A two-compartment cooling apparatus which achieves a plurality of refrigeration cycles by controlling refrigerant paths, thus increasing cooling efficiency and cooling speed of the cooling apparatus. A compressed refrigerant provided by a compressor is selectively provided to first and/or second evaporators via first, second and third expansion units and a path control unit. The path control unit controls the flow of the refrigerant through the expansion units and the evaporators to vary the cooling in the respective compartments in response to temperature measurements made in the respective compartments.
