水滴となつて落下して周囲をぬらすおそれがある。Generally, this type of water chiller consists of a refrigerant compressor, a condenser, a capillary tube, and a heat exchanger for chilled water, which are sequentially arranged to form a refrigeration cycle, thereby producing chilled water or chilled juice for drinking. I'm starting to do that. However, since the above-mentioned water coolers are used in hot places or during the summer, the atmosphere in which the water coolers are installed will have high humidity, and condensation will form on various cooling equipment and electrical equipment, causing water droplets to form. There is a risk of it falling and getting the surrounding area wet.

In view of the above-mentioned points, the present invention sequentially includes a refrigerant compressor, a condenser, a first capillary tube, a three-way control valve, a second capillary tube, and a cold water heat exchanger to configure a refrigeration cycle. A dehumidifying evaporator is provided between the refrigerant compressor and the Ξ-direction control valve, and when the chilled water reaches a certain cooling temperature, the three-way control valve is operated to close the first capillary. The refrigerant in the tube is supplied to the evaporator for dehumidification, thereby dehumidifying the fluid in the atmosphere where the device is installed, improving the efficiency of cold water generation, and also preventing condensation from forming on electrical equipment, etc. The present invention provides a water cooler for the purpose of:

Further, a part of the cold water tank 9 is provided with a temperature regulator 15 such as a thermostat, and this temperature regulator 15 is configured to allow the water in the cold water tank 9 to reach a certain cooling temperature in the heat exchanger 7. Then, the three-way control valve 5 is operated,
The refrigerant in the first capillary tube 4 is transferred to the evaporator 11.
and simultaneously drives the blower 12. Therefore, the refrigerant compressor 2 is now driven to compress the refrigerant, and the refrigerant is transferred to the condenser 3 for heat exchange to become a liquid refrigerant. , transferred to the cold water heat exchanger 7 via the second capillary tube 6, where heat exchange is performed, and then,
The refrigerant is refluxed to the refrigerant compressor 2. When the heat exchanger 7 cools the water in the cold water tank 9 to a certain temperature, the temperature regulator 15 operates the three-way control valve 5 to cool the water in the first capillary tube 4. Since the air blower 12 is driven at the same time as the air is supplied to the evaporator 11, the evaporator 11 is rapidly cooled.
The atmospheric fluid is forcibly cooled. Further, the cold water tank 9 is kept in a cold state. Furthermore, the temperature regulator 15 may be replaced with a timer or an electrical time circuit, for example.
