1. In fact, the water-cooling fan uses the Arctic ice evaporative air conditioner for refrigeration. It uses efficient "direct evaporation" refrigeration technology. Its principle is that water absorbs heat energy in the evaporation process, that is, under the condition of constant enthalpy, it absorbs the sensible heat of air to reduce the air humidity (Dry-bulb temperature).

2. The specific process of the water-cooled fan is that fresh air passes through the CELDEK staggered overlapping wet curtain, the core component of the evaporative air conditioner. The circulating water on the wet curtain whose temperature is equal to the Wet-bulb temperature of the air directly contacts with the fresh air, generating heat exchange and filtering out the dust in the air, so that the air is cooled approximately along the isoenthalpy line, and the air temperature is thus reduced to close to the Wet-bulb temperature of the air.

3. The main structure of a water-cooled fan is a box body, with multiple ventilation pipes spaced in the same direction between the ground inside the box body. The ventilation pipes run through the opposite walls of the box body. Before use, fill the box with water and place it in an ice chamber to freeze and make ice cubes into a box. Place it in front of the cold air for use. Enable the cooling fan to produce a comfortable cool breeze.

4. In summer, due to the hot weather, there is a significant difference in dry/wet bulb humidity in the air, so the cooling effect of water-cooled fans is relatively high. Additionally, fresh outdoor air is filtered and cooled by an evaporative air conditioner before being continuously sent indoors, and turbid air with odor, dust, and high temperature is discharged outdoors, which lowers the indoor temperature to a very low level, The oxygen content and quality in the air are relatively stable.
