The brief review on the refrigerants and their working principles

The impacts of different refrigerants on the ozone layer deterioration and the increase of global warming are becoming a growing concern in today's climate. Chlorine with halogenated hydrocarbons, known as CFCs, which are utilized as refrigerants in refrigerators and air conditioners in all home, industrial, and commercial applications, is the main cause of this environmental impact. This article looks at the many refrigerants that have been developed in order to solve a variety of other problems, such as flammability and toxicity of refrigerants from generation to generation. By examining the physical, chemical, environmental, and safety characteristics of several refrigerants. With the advancement of refrigeration and air conditioning technology, we must have heard that science is currently in the process of selecting or creating an ecologically benign refrigerant to replace previous refrigerants. Furthermore, next-generation refrigerants are designed to have a ‘zero’ ozone depletion potential and a low global warming potential, making them both ecologically stable and benign.
