ADVANCED REFRIGERATION AND AIR- CONDITIONING SYSTEMS

Abstract 

Refrigeration application at the domestic, commercial and industrial levels are becoming an integral part of the present day living. The demand and supply of refrigeration systems is increasing day by day with the changing lifestyle. The existing compressor – based refrigeration (i.e., mechanical refrigeration) system has reached the maximum level of innovation. For the last few decades, there has not been any significant increase in the efficiency (i.e., coefficient of performance, COP) of the system. Moreover, with the increasing awareness of environmental degradation, the production, use and disposal of ChloroFluoro carbons (CFCs) and Hydro Chlorofluorocarbons (HCFCs) as refrigerants in mechanical refrigeration system has become a subject of great concern. However, such system are being developed using more ecofriendly refrigerants viz., air, CO2 , NH3, etc. Besides, efforts are being directed to develop other types of refrigeration technologies e.g., magnetic refrigeration, thermoelectric refrigeration which will be more ecofriendly,
cost effective, efficient, simple in design, convenient and reliable.
