Water-Lithium Bromide Vapor Absorption Refrigeration System. 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. In the absorber, the lithium bromide absorbs the water refrigerant, creating a solution of water and lithium bromide.
3/30/2018 · 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. In…
The lithium bromide absorption refrigeration system uses a solution of lithium bromide in water. Water is being used as refrigerant whereas Li-Br is a highly hydroscopic salt, used as absorbent. The Li-Br solution has a strong affinity for water vapour because of its very low vapour pressure.
Absorption refrigeration systems are an alternative to vapor compression s ystems due to the increase of the environmental probl ems and electricity cost.
Absorption systems typically employ lithium–bromide (Li–Br) and water, with the Li–Br being the absorber and the water acting as the refrigerant. Such systems can cool the inlet air to 50°F (10°C). Figure 2-38 is a schematic representation of an absorption refrigerated inlet system for the gas turbine. The cooling shown on the psychometric chart is identical to the one for the mechanical system.
Water-lithium bromide systems are widely used in the construction of refrigeration applications.These systems use water as the refrigerant, so they are not suitable for use in all applications where the evaporator temperature is below 32F (0C). Lithium bromide is used as the absorbent.
7/25/2015 · Vapour absorption refrigeration systems using water-lithium bromide pair are extensively used in large capacity air conditioning systems. In these systems water is used as refrigerant and a solution of lithium bromide in water is used as absorbent. it is having lot more of advantages like except for two small centrifugal pumps, there are no moving parts so less number of moving parts, 12/13/2020 · Absorption (Outline 6.1.1, 6.2.1) 1. What is the refrigerant in the water and lithium bromide absorption refrigeration system ? _____ 2. What is the absorber solution made of in the lithium bromide absorption system ? _____ 3. Why do Li Br systems need to be hermetically sealed? _____ Purging Refrigeration Systems . 4.
A typical schematic of the absorption refrigeration system is given in the Figure 4.3. Li – Br -water absorption refrigeration systems have a Coefficient of Performance (COP) in the range of 0.65 – 0.70 and can provide chilled water at 6.7 °C with a cooling water temperature of 30°C.
