The water cooler fan, also known as the evaporative air cooler. It adopts high-efficiency "direct evaporative" refrigeration technology. The principle is based on the fact that water absorbs heat energy during the evaporation process, that is, under the condition of constant enthalpy value, it absorbs the sensible heat of the air and reduces the air temperature (dry bulb temperature). . The working process is: when fresh air passes through the core component of the water-cooled fan-the interlaced moiré air heat exchanger, the water whose temperature is equal to the wet bulb temperature of the air will directly contact the fresh air to generate heat exchange and filter out the dust in the air. The air is cooled by an isenthalpy change, and the temperature eventually drops to close to the wet bulb temperature.

Because of the following advantages of its products, it is more and more recognized by people, so they can be used.

1. Low investment and high efficiency: Compared with the installation of air-conditioners and water-cooled fans in the same area, water-cooled fans are 1/2 of the total air-conditioning investment.

2. Low power consumption, only one kilowatt hour per hour: Compared with water-cooled fans, installing air conditioners in the same area consumes only about 1/9 of traditional air conditioners.

3. The cooling effect is particularly strong: in the southern region, the water-cooled fan unit can generally reduce the temperature by 5 ~ 10 ℃, and in the hot and dry area, the unit can cool up to 5 ~ 15 ℃, and the temperature will drop quickly.

4. Good air quality: The water-cooled fan integrates ventilation, ventilation, purification, deodorization, and cooling to increase the oxygen content of the air and improve work efficiency. The fresh air is operated under positive pressure, filtering the dust below 80% micron in the air, removing harmful gases, and effectively preventing "air conditioning diseases".

5. Humidity adjustment: Humidity adjustment for workplaces that need to increase humidity.

6.Convenient installation and maintenance: The water-cooled fan can be installed along the facade of the outer wall, and the installation is beautiful, does not occupy indoor space, does not require professional maintenance, and saves maintenance costs.

7. Wide range of use: widely used in crowded places, production places with heating equipment or high-temperature heat sources, places with polluting gas, strong odor or dust, and places with high air quality requirements.
