Environmentally-friendly air conditioners, water-cooled air conditioners, and professional slang are called evaporative air conditioners and evaporative cooling fans. Nowadays, we are habitually calling it environmental protection air conditioners, water curtain air conditioners, wet curtain air conditioners, etc., but many people in the north The name is different. In the Jiangsu and Zhejiang areas, environmental protection air conditioners are called, such as coolers, fresh air ventilators, and so on. In fact, Xiaobian here reiterates that, as a professional evaporative air conditioner provider, everyone habitually calls it an environmentally friendly air conditioner. The name is based on everyone's habits, and this cannot be changed. Ningbo air cooler, Ningbo air cooler

Why is environmentally friendly air-conditioning also called a cooler?

However, the evaporative air conditioner (environment-friendly air conditioner) uses the natural physical phenomenon of "water evaporates to absorb heat, and the evaporation area affects the evaporation efficiency." When the fan is running, a negative pressure is generated in the air conditioner cavity, so that the air outside the machine flows into the porous humid The surface of the wet curtain enters the cavity, and the water on the wet curtain evaporates while the air and water are in full contact, taking away a large amount of sensible heat, and reducing the dry bulb temperature of the air passing through the wet curtain to the wet bulb temperature close to the air outside the machine. That is, the dry bulb temperature at the outlet of the evaporative air conditioner is 5-12 ° C lower than the outdoor dry bulb temperature (up to 15 ° C in dry and hot areas). The drier and hotter the air, the larger the temperature difference and the better the cooling effect. In other words, the hotter the outside, the cooler the room, the environmentally friendly air conditioner is so powerful!
