WebbOn the other hand what may be called the physics of refrigeration receives a good deal of consideration and the scientific principles involved are treated fairly fully. Two chapters, one on the laws governing the evaporation of water and sublimation of ice (by Dr. POWELL), and the other (by the Editor) on thermal insulation, are valuable additions to … WebbBasic & Definition. The refrigeration cycle is a thermodynamic cycle that generates refrigerating effects with the use of mainly an evaporator, compressor, condenser & expansion valve. This process is basically a thermodynamic process where the working fluid absorbs the heat from the surrounding at a low temperature and reject the heat to …
