Magnetic Refrigeration: An Environment-friendly Cooling Technology

Abstract

Since the last few decades, global warming has threatened the sustainable ecology and environment. Its dominance on climate change is well known and largely discussed agenda at most of the international meets. However, the existing conventional vapor compression based refrigeration technology, which typically uses coolant gas like chlorofluorocarbons, tetrafluoroethane, freon, isobutene, etc., has considerable direct/ passive roles in global warming. Hence, the universal technique involved in refrigerators and air conditioners, an essential part of our daily life, is deteriorating the issues. Furthermore, the traditional vapour compression refrigeration technique has its limitation in energy efficiency with the high capital cost of the compressor and the electricity needed to operate the compressor.
