As shown in Figure 1 showing the shell and tube type water cooler and Figure 2 showing the conventional technology of the multi-tube coil type water cooler, in the antifreeze thermostat for the water cooler of the chiller unit, the main body is housed in an electrical box, etc. , the temperature sensing part is attached to the cold water outlet side of the water cooler.
In this case, during normal operation, the chilled water temperature on the chilled water outlet side is the lowest, so freezing can be prevented by stopping the operation of the chiller unit by detecting the outlet side temperature. However, if water is no longer sent to the water cooler due to a water outage, the colder water will collect at the bottom of the water cooler and freeze from the bottom. Detecting the cold water temperature near the temperature sensing part of the water cooler cannot prevent the cold water from freezing at the bottom of the water cooler. Related to these is Utility Model Application No. 52-91557.

In this invention, by using a gas-filled antifreeze thermostat attached to a water cooler, it is possible to detect the temperature even in the capillary that connects the thermostat's temperature sensing part and the main body. By bringing the capillary into contact with the area in the water cooler where freezing is first thought to begin during a cold water outage, destruction due to freezing is prevented.

The invention is shown in FIGS. 3 and 4. Figure 3 shows the case of a shell and tube type water cooler, and Figure 4 shows the case of a multi-tube coil type water cooler. , the capillary connecting the main body is wrapped around or in contact with the lower part of the water cooler on the cold water inlet side. During normal operation of the chiller unit, the antifreeze thermostat temperature sensor installed on the cold water outlet side, which has the lowest temperature, detects the chilled water temperature and prevents the chilled water from freezing.If the chiller unit is cut off, the water temperature will be adjusted to the earliest possible temperature. By detecting the water temperature with the capillary of the antifreeze thermostat that is wrapped around or in contact with the lower part of the water cooler, it is possible to prevent the water cooler from being destroyed due to freezing of the cold water.
