Experimental Investigation of Using Evaporative Air Cooler for Winter Air-Conditioning in Baghdad

This paper presents an efficient methodology to design modified evaporative air-cooler for winter air-conditioning in Baghdad city as well as using it for summer air-conditioning by adding a heating process after the humidification process. laboratory tests were performed on a direct evaporative co...
