This solution is pumped by the pump to the generator where the solution is heated. The capital cost of VAM is higher compared to compression systems, but when viewed in totality of reduced electrical service size, transformer, switchgear, cabling and lack of need for an equipment room, the VAM becomes comparable to compression systems. The most widely used absorption refrigeration system is the ammonia-water system shown inFigure 1, where ammonia (NH 3) serves as the refrigerant and water (HO 2) as the transport medium. For applications above 32F (primarily air condition˚ - ing), the cycle uses lithium bromide as the absorbent … The principle of vapour absorption was first discovered by Michael Faraday in 1824 while performing a set of experiments to liquefy certain gases. A.T.Rego et al [16], who designed and tested a prototype for an absorption refrigeration system, powered by the exhaust gas heat of a 260 kW diesel engine. Simultaneously the heat released to absorb the vapor is removed by air. The absorption … In a water-lithium bromide vapor absorption refrigeration system, water is used as the refrigerant while lithium bromide (Li Br) is used as the absorbent. Fateme A.
