Mathematical modelling of an air conditioner using evaporative cooling (without compressor)(COP =10.99)

Air conditioners are used to provide thermal comforts in extremly hot conditions. But these are very high power consuming machines. An attempt is made to make an air conditioner using the both form of evaporative cooling. Evaporative cooling is the most powerful and cheapest cooling technology. When air blow over the water, it gets cool. Water evaporated with blowing air, utilize latent heat from water itself thus reducing overall temperature of air and water. For details in evaporative cooling, Please click on below link: http://athermocreation.blogspot.in/2017/10/evaporative-cooling.html As we know to increase the temperature of one liter of water by one degree, Sensible Heat required is 4.187 kJ. But to evaporate one kg of water, latent heat required is 2250 kJ which is almost 550 times the sensible heat. So to lower the temperature of water only a small portion of water evaporation required. Evaporative technology is of two types: 1. Direct Evaproative technology
