Evaporative air conditioner is a necessary workshop equipment for enterprises to recruit workers in the new century. The installation location is generally determined by the product type, and the higher the precision of the mold used. So, how do evaporative air conditioners teach you how to choose a location? It should be installed outdoors and require full fresh air movement. Return air is not allowed. It should be installed as much as possible in places with good air quality in the surrounding environment. Do not install it at exhaust outlets with odors or peculiar gases, such as polishing, toilets, kitchens, etc. Next, environmentally friendly air conditioners can be installed on walls, roofs, or outdoor floors, and long air ducts should be avoided (such as KS-18 type). Generally, the length is 15-20 meters, and air duct bends should be minimized or not used as much as possible. Evaporative air conditioners require opening certain doors or windows to facilitate ventilation. If there are not enough doors and windows, an exhaust room should be installed to ensure that the exhaust volume is 80% of the total air supply volume of the environmentally friendly air conditioner, and its structure should support twice the weight of the entire machine and maintenance personnel.
