Abstract
A cooling storage cabinet includes a freezing compartment, a refrigerating compartment, a compressor, a three-way valve, and a control circuit. The control circuit is configured such that: when an internal temperature of the freezing compartment becomes lower than a lower limit temperature during R-compartment F-compartment alternate cooling, starting R-individual overcool preventing control is requested, the rotational speed of the compressor is decreased by one stage and, subsequently, the three-way valve enters 'R-side open state', and individual cooling of the refrigerating compartment is executed; thereafter, every 30 seconds, the rotational speed of the compressor is decreased by one stage; when the refrigerating compartment temperature becomes lower than a lower limit temperature, stopping R-individual overcool preventing control is requested; and then, the process shifts to individual cooling of the freezing compartment, and after the freezing compartment again becomes lower than the lower limit temperature, the compressor is stopped.
