PROBLEM TO BE SOLVED: To integrally and rationally control a showcase and a refrigerator to attain high freshness management of merchandise, energy saving, facilitation of maintenance and optimization of refrigerator capacity. SOLUTION: This showcase cooling device is composed of one or more showcases wherein the flow of a refrigerant to an evaporator is controlled on/off through solenoid valves based on deviation between the temperature of blowoff air and the set value, and the common refrigerator constituting a refrigerating cycle with the showcases. The showcase cooling device is provided with a temperature sensor for measuring the temperature of a merchandise housing part of each showcase, and a temperature set value correcting part for correcting the set value of the blowoff air temperature based on the measured temperature.
