Analysis of cooling principle of air cooler

Foodjx guide: Cooling fan, divided into Wanhe refrigeration industrial cooling fan and household cooling fan, industrial cooling fan is generally used in cold storage, cold chain logistics and refrigeration environment, household is also called water-cooled air conditioning, is a collection of cooling, ventilation, anti- Evaporative cooling and ventilation unit with dust and deodorization.
When the fan is running, a negative pressure is generated in the cavity, so that the air outside the machine flows through the surface of the porous wet curtain, and the dry bulb temperature of the curtain air is reduced to a temperature close to the wet bulb of the outside air, that is, the dry bulb of the outlet of the air cooler. The temperature is 5-12 °C lower than the outdoor dry bulb temperature (up to 15 °C in dry heat), the hotter the air, the greater the temperature difference, the better the cooling effect. Since the air is always introduced into the room from outside (this is called a positive pressure system), it can keep the indoor air fresh. At the same time, because the machine uses the principle of evaporation and cooling, it has the dual functions of cooling and humidifying (relative temperature can reach 75%). Left and right), used in textile, knitting and other workshops, not only can improve the temperature and temperature increase conditions, but also purify the air, reduce the needle breakage rate in the needle spinning process, and improve the quality of the needle textile products.
The air cooler (evaporative air conditioner) is surrounded by a honeycomb wet curtain using special materials, which has a large surface area, and the wet curtain is continuously humidified by the water circulation system; the high-efficiency low-noise energy-saving fan is installed in the wet curtain air cooler. When the fan is running, the negative pressure of the wet curtain air cooler causes the air outside the machine to flow through the porous wet curtain into the machine, and the heat of the water on the wet curtain absorbs heat, forcing the air passing through the wet curtain to cool down. At the same time, since the water on the wet curtain evaporates toward the air flowing through the wet curtain, the humidity of the air is increased, so the wet curtain air cooler has the dual functions of cooling and humidifying.
