ーケースの温度制御装置。 In an open refrigerated case equipped with a night cover, there is a thermistor that detects the temperature of circulating cold air, a resistor connected in series to the thermistor, a normally closed electromagnetic switch connected in parallel to this resistor, and a normally closed electromagnetic switch that opens and closes the night cover. Interlockingly, the solenoid of the electromagnetic switch and the switch that turns on and off the power to the interior lighting are connected to both ends of the thermistor and resistor, and the combined resistance value of the thermistor and resistor is
A temperature control device for an open refrigerated case, comprising a control circuit that starts operating a cooling device when a preset upper limit is reached, and stops the operation when a lower limit is reached.
