Dual outlet air conditioning fan

Air conditioning fanThe cooling principle of an evaporative air conditioner is that when the fan is running, negative pressure is generated inside the chamber, causing the outside air to flow through the wet curtain surface with multiple air cooler holes, forcing the dry bulb temperature of the air passing through the curtain to drop to near the wet bulb temperature of the outside air. That is, the dry bulb temperature at the outlet of the air cooler is 5-12 ℃ lower than the outdoor dry bulb temperature (up to 15 ℃ in dry and hot areas). The hotter the air, the greater the temperature difference, and the better the cooling effect. Due to the fact that air is always introduced from the outside into the room (this is called a positive pressure system), it can maintain the freshness of indoor air; At the same time, due to the use of evaporation cooling principle, the machine has dual functions of cooling and humidification (relative temperature can reach about 75%). When used in textile, knitting and other workshops, it can not only improve the cooling and humidification conditions, but also purify the air, reduce the needle breakage rate during the needle spinning process, and improve the quality of needle textile products.

The air cooler (evaporative air conditioner) is surrounded by honeycomb shaped wet curtains made of special materials, which have a large surface area and are continuously humidified through a water circulation system; A low-noise energy-saving fan is installed inside the wet curtain air cooler. When the fan is running, the negative pressure generated by the wet curtain air cooler causes the air outside the machine to flow through the porous and moist wet curtain and enter the machine. Due to the evaporation and absorption of heat by the water on the wet curtain, the air passing through the wet curtain is forced to cool down. At the same time, due to the evaporation of water on the wet curtain towards the air flowing through it, the humidity of the air is increased. Therefore, the wet curtain air cooler has a dual function of cooling and humidifying.
