Energy conservation and the requirement of renewable sources are becoming more critical because fossil fuels are limited and have a negative impact on the environment. The world needs to find new energy sources because we can’t keep using fossil fuels forever. Coal, oil, and gas make up 77.5% of energy usage worldwide, according to the IEA. In 2021, air conditioners were the only devices that used 110 million units of electricity. One of the few options is to use solar power to make things like refrigeration systems work. This solar-powered refrigeration system is to be designed using vapor absorption refrigeration systems. The system works by using a parabolic trough to collect sunlight and then using that sunlight to heat the water. This water will travel to a heat exchanger fabricated in the VARS, which will increase the temperature of the refrigerant and hence power a cooling system that uses NH3-H2O.
