Color:Silver  |  Size:42inch An Air Cooler Is Not 'just A Fan': Air Coolers Use The Natural Process Of Water Evaporation To Cool Incoming Hot Air And Use A Powerful Fan To Expel The Newly, Cooled Air. The Temperature Of Dry Air Can Drop Significantly When Liquid Water Transforms To Water Vapor (Through Evaporation). An Air Cooler Is Not An Air Conditioner: Air Conditioners Require A Chemical Cooling Refrigerant And An Energy-consuming Compressor To Transform Hot Air Into Cool Air. The Hot Air Must Be Released Outside The room. The More Complex Composition Of Air Conditioners Also Make Them More Expensive To Purchase And They Consume Significantly Higher Electricity During Use.
