【 摘 要 】

The refrigeration and air-conditioning sector is now undergoing a crucial phase where all the existing conventional refrigerants are being permitted to be neither produced nor consumed. For a better future, there is an immediate demand to look for clean refrigerants which are eco-friendly. The world is now looking for the refrigerants which do not contribute to the ozone layer depletion and global warming. The use of natural refrigerants like CO2, NH3 and hydrocarbons such as R290, R600, R600a and blends of hydrocarbons are possible solution to this problem and are being used efficiently in many systems. In this paper the importance of reconsidering the use of natural refrigerants to replace the synthetic refrigerants has been discussed. A review on the different systems where natural refrigerants are being used and modifications to such systems that could ensure better efficiency has been presented.
