This is my phase I thesis work carried out in PSG College of Technology during my master's in Energy Engineering. This work conveys the use of solar thermal collectors and phase change materials in absorption chiller to cool the telecommunication shelters in India. This technology overthrows the usage of conventional air conditioners to cool the telecom shelters, thereby, saving a lot of money and reducing carbon emissions in a country where fossil fuels are diminishing in a faster pace than expected. Even though this work is a design and analysis genre, the proposal is a first of its kind in telecom sector,therefore, interested people can go through and drop your comments below.
