The exigency for energy is increasing with developing technology and rapid rise in world population. The increasing energy rates and the urging need for environmentally friendly refrigerants has led scientists in the fields of refrigeration engineering to develop technologies for the utilization of conventional renewable energy resources. The deployment of insolation energy for refrigeration systems would help to unravel the existing energy crisis along with environmental protection. Hence an exertion has been made to understand the various approaches taken to make use of solar energy for refrigeration systems and its potential applications.
