In a solar air cooler, the solar heat is absorbed by the thermal collectors. This heat is then used to charge the inbuilt batteries. Moreover, the energy derived from the sunlight is also used to separate the mixture of refrigerant and absorbent fluids. On the other hand, in different types of solar air coolers, the moist air is made to pass over a wheel which is also known by the desiccant wheel. This wheel comprises moisture trapping materials. These moisture trapping materials are responsible for the cooling action in your home.
