Presented by Shailendra S Chauhan ME 3 rd yr Refrigerant development a brief history Water is one of the earliest substances to be used as a refrigerant although not in a closed system. These thick wall containers are lightweight, economical and made with a tight fitting lid and molded EPS body. They are typically used for 2-4 day shipments. Dr Alka Bani Agrawal. Professor,Mechanical Engg. UIT,RGPV. History Of Refrigeration. Refrigeration relates to the cooling of air or liquids, thus providing lower temperature to preserve food, cool beverages, make ice and for many other .. Hydrochlorofluorocarbons, or HCFCs, are chemicalsthat are mainly used as refrigerants. Unfortunately,releases of HCFCs deplete the Earth see at right) that satisfies the IATAmarking and labeling requirements when accurately completed.
