Design and Fabrication of Solar Modified Air Cooler for Centre Library

The potential for solar air conditioning is enormous. Summertime, when cooling loads are at their peak, is when sunlight is most abundant. Unfortunately, the technologies that are now in use cannot effectively harness this enormous resource. For instance, photovoltaic (PV) cells are pricey and need a significant area of the roof to generate enough electricity to run an air conditioner. These panels can cost up to ten times as much as a typical air conditioner. The new solar air conditioner adopts a very different strategy. It is a thermally powered system that varies from earlier thermal systems in that it has inexpensive energy storage and is made to function with low-temperature solar collectors. A concentrated salt solution (desiccant, calcium chloride) that can be utilised to provide dehumidification is a kind of energy storage. In order to offer air conditioning, a cooler with a unique heat exchanger design combines cooling from water evaporation with dehumidification from the desiccant.
