Spring doesn't stay long, and then it’s back to the sticky hot summer days. As summer heat becomes unbearable, air conditioners in every house become active and yet again the electric bills start soaring, disgustingly adding salt to the wound. And if your country happens to be within the tropical boundaries, this further makes the situation hostile.
Conventional air conditioners are efficient- there's no doubt about that- but they come with huge costs in the form of electric consumption and the associated utility bills. More electric usage from such units would mean that more hydro-electric and nuclear power plants will have to be installed in the future, resulting in the destruction and occupation of precious land and other natural resources in the process.
However, interestingly of late, scientists have started looking for many different renewable methods for replacing the above rather costly counterparts. Air conditioning is no exception and is at the core of their research.
Water as we know is the basis of life on this planet and moreover has unconditionally provided us with simple solutions to most of the energy related problems. Whether it’s a hydroelectric power station or a cheaply operated evaporative air conditioning unit, water forms the main and ubiquitous element everywhere - a magical fluid that’s available FREE of cost and plentifully on this planet.
Before moving into the proposed design of our homemade air conditioner, let’s study a few of the following conventional AC designs and their drawbacks:
