ABSTRACT:
A state-of-the-art review is presented of the different technologies that are available to deliver refrigeration. The demand and supply of refrigeration systems is increasing day by day with changing lifestyle. In last few decades with excess use of CFCs and HCFCs, we have degraded the environment to larger extent. This resulted into adverse effects such as Ozone depletion and Global warming. So technological development based on improvement in energy efficiency should be done. The modern systems include the technologies which are cost effective, energy effective and economically feasible. The new emerging technologies are mainly focused on protection of globe. The review covers introduction about refrigeration and air conditioning, modern trends in refrigeration and air conditioning such asTURBOCOR compressor using magnetic bearing eliminates the problems of lubrication, noise & friction; Paraflow technology which includes pumping the fluid parallel to both the high temperature and low temperature generator which improves the efficiency; Green building consists of thermal insulation of wall, Indoor Air Quality & Non-Conventional Refrigeration; Thermal storage is used to generate ice during Non-Peak Period and use this ice for Refrigeration during Peak period. This trends requires high initial cost but is useful to reduce the ozone effect.
1. INTRODUCTION:
The word ‘refrigerate’ means to chill or freeze a substance, i.e. to lower its temperature by removing some of its heat. Thus Refrigeration is a process
