WebMagnetic Refrigeration A magnetic material is situated within a magnetic field. This causes it to undergo the magnetocaloric effect and heat up. When the material is no longer exposed to the magnetic field, it cools down. This process can be used to transfer heat out of a condition space similarly to modern refrigerants. Especially now that the WebRefrigerants like sulfur dioxide and methylchloride were causing people to die. Ammonia had an equally serious toxic effect if it leaked. Frigidaire discovered a new class of synthetic refrigerants called halocarbons or CFCs (chlorofluorocarbons) in 1928. Then part of General Motors, the company sewed up all the patents.
