Development of solar powered air conditioner using flat plate collector

Abstract

Air conditioning systems that utilize solar energy are generally cost-effective when used to provide cooling requirements in commercial, home, and industrial buildings as well. The utilization of solar energy is the least compared to the various form of renewable energy sources. Air conditioning is required in hot and humid climates such as India to maintain thermal comfort in closed rooms. The widespread use of these air conditioning systems will significantly increase electricity demand during the summer. The country is facing major power supply problems due to power shortages. In this study, solar collector designed as per Delhi’s geological coordinates and 4 different times of hours i.e., 12, 14, 16 & 18 on 11 July of a year. From the numerical results, the flat plate collector in 12, 14, 16, & 18 h in a day on 11 June in Delhi, at 12 times of hours when the sun is at peak. From the temperature profiles, it is evident that the temperature on the absorber is very high and also efficiency. It was concluded that the efficiency and temperature of absorber at different 4 points of times in a day which helpful for researchers to design solar-powered air conditioner using a flat plate collector.
