With advancement in science and technology, solar energy are now able to be utilized in several ways. One of the upcoming uses of solar energy is operating air conditioners.
Although it sounds such as a contradiction, a solar air conditioner works utilizing the sun’s energy to cool our homes. Such air conditioners have great application in arid areas where there’s abundant sunlight. Air-con becomes a necessity such areas and with bright sun as the origin of energy, solar air conditioners are the right choice.
Forms of Solar Air Conditioners
Solar air conditioners are either active or passive. Active solar air conditioners are of two types – solar absorption cooler and solar desiccant cooler.
In a solar absorption cooler, solar heat is absorbed by thermal collectors and this heat can be used to separate your lives a combination of refrigerant and absorbent fluids. The refrigerant fluid is then condensed and best tv evaporated. This method cools the air and this cold air is sent to the house. The absorbent fluid reabsorbs the refrigerant and the method is repeated.
In solar desiccant coolers, moist air passes over a “desiccant wheel” which has moisture trapping materials. The moisture in the air is absorbed by these materials, making the air cool. Fans are then used to send this cold air out to the room. This kind of solar coolers requires lesser temperatures than absorption coolers.
