That is, the dry bulb temperature at the exit of the cooling fan is 5-12 °C lower than the outdoor dry bulb temperature (up to 15 °C in the dry heat zone), the hotter the air is, the larger the temperature difference is, the better the cooling effect is.

Since the air is always introduced into the room from outside, this time is called the positive pressure system, so 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 about 75%). ), 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 is surrounded by a honeycomb wet curtain with 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, and the air is wet when the fan is running. The negative pressure generated by the 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 the 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.
