Technology Involving Absorption Refrigeration Run by Solar Energy: A Review

Abstract

In the modern period, "energy" has joined the ranks of men, machines, and money as the fourth pillar of the industrial complex. Every business relies on energy as a need, and energy is a crucial factor in determining the industry's economy. The majority of sectors currently rely on nonrenewable conventional energy sources. Industry relies heavily on refrigeration and air conditioning as a key source of energy consumption. Unlike in developed countries where electricity is ubiquitous, certain regions of India lack electricity altogether. There is already a high cost of energy from non-renewable resources, and that cost will continue to rise over time. These sources are both harmful and depleting in nature, which causes environmental problems. A important answer to the energy and environmental problems is to use renewable energy, such as solar energy, to cool buildings. Because of the sun's enormous power, solar energy is a viable substitute for some nonrenewable energy sources, such as coal and oil. When electricity is scarce or too expensive, cooling systems might turn to solar energy as a substitute. A large number of solar-powered cooling systems have been put into use around the world for home use. Because of a lack of knowledge about solar energy in India, much of it has been wasted in the past. To dry food grains and clothes, the majority of solar energy is used. However, in recent years in India, the vast majority of individuals have gone solar. This research explores a variety of solar-powered vapour absorption cycles using various refrigerants.
