摘要： 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.

摘要： When an internal temperature of a freezing compartment becomes lower than a lower limit temperature TF(OFF) during R-compartment F-compartment alternate cooling, a request for start of R-individual overcool preventing control is made. Then, the rotational speed of the compressor is decreased by one stage and, subsequently, a three-way valve comes to a “R-side open state”, and thus individual cooling of the refrigerating compartment is executed. Thereafter, after a set time, the rotational speed of the compressor is decreased by one stages. When the refrigerating compartment becomes lower than a lower limit temperature TR(OFF), a request for stop of the R-individual overcool preventing control is made. Then, the process shifts to individual cooling of the freezing compartment and then, after waiting for the freezing compartment to again become lower than the lower limit temperature, the compressor is stopped. When shifted to the individual cooling of the refrigerating compartment, the rotational speed of the compressor is drastically decreased in a short time, i.e. the cooling capacity is drastically decreased.
