Abstract
A refrigerator has a cold storage and freezer zones with individual fans and evaporators, a switching valve that allows refrigerant to flow simultaneously through each zone or through only one of the zones and a control which when power is supplied causes simultaneous flow, starting the compressor and a condenser fan while driving the cold storage fan at a high speed and the freezing zone fan at a low speed until such time that a set point time has been exceeded or the temperature set points of the zones has been reached by cooling.
