PURPOSE: A time divisional multi-cycle type cooling device is provided to time divisionally control the operation time points for respective evaporators and the conversion time point of a refrigerant channel, thereby making the temperatures of a freezing chamber and a refrigerator compartment optimally. CONSTITUTION: A time divisional multi-cycle type cooling device includes a compressor, a condenser(202), and two closed loop refrigerating cycles. The first closed loop refrigerating cycle is formed by connecting an evaporator(106) of a refrigerator compartment to an evaporator(108) of a freezing chamber via a second capillary tube(206). The second one is formed by connecting the condenser to the evaporator of the freezing chamber by a third capillary tube(208). A three-way valve(210) controls the refrigerant flow between the first and second closed loop refrigerating cycles. |
