For years refrigeration and more specifically refrigerants have been a major contributor to the global warming and ozone depletion problems we are facing. Manufacturer’s have been experimenting with different refrigerants, use of less refrigerants, refrigerants that don’t contribute to the ozone depletion potential (ODP) but do contribute to the global warming potential (GWP). The new push is for environmentally friendly refrigerants or as they are called, natural refrigerants such as water or carbon dioxide.
General Electric has possibly revolutionized the refrigeration and air conditioning industry as we currently know it but designing a refrigerant free means of mechanical cooling. They have found that they can make a fluid, such as glycol, heat or cool using magnets and magnetic fields. This technology removes the need for refrigerants, compressors and is significantly more energy efficient than the traditional form of refrigeration. Magnetic Refrigeration
