れている。Conventional technology Conventionally, as a water-cooled thermal storage type beverage cooling control device, a cooler, which is an evaporator of a refrigerator, is installed in a cooling water tank filled with water.
A beverage cooling coil, which is part of the beverage supply pipeline, and an electric agitator for stirring water are placed in an immersed manner, and a refrigerator is operated to constantly make ice, called an ice bank, around the cooler in the water tank. However, there is a well-known device that uses the amount of heat stored in ice to keep a water tank at a low temperature and cool a beverage. In the case of this device, in order to ensure the amount of heat storage in the ice, it is necessary to keep the amount of ice made around the cooler constant. A current is passed through a sensor electrode installed near this cooler, and a change in resistance between the electrodes is detected depending on the amount of ice that has formed on the electrode. A detection circuit is used to convert the change in resistance into a voltage change. A commonly used method is to start and stop the refrigerator operation by comparing the voltage with a predetermined voltage.
