Increasing demand for
lithium bromide in refrigeration and drying applications is expected to in turn drive growth of global
lithium bromide market over the forecast period.
Exergy analysis: An absorption refrigerator using
lithium bromide and water as the working fluids.
Despite a number of studies on the viscosity (Isono 1984; Wimby and Berntsson 1994), experimental data on concentrated solutions are still lacking for the
lithium bromide and lithium chloride aqueous solutions in a wide range of concentrations.
To calculate the chemical Exergy of
lithium bromide as a pure component the equation 16 is applied [27, 28].
At this low temperature, highly concentrate
Lithium Bromide (LiBr) absorbs the water vapour given off in the boiling process very effectively.
Similar to conventional absorption chillers, the ADsorption chiller uses recovered heat from the power generating process instead of electricity to produce chilled water, but one of the many benefits is that it does not require the use of
lithium bromide.
Halide salts such as lithium chloride and
lithium bromide are very strong desiccants: a saturated solution of
lithium bromide can dry air to 6% relative humidity and lithium chloride to 11%.
For one thing, desiccants such as
lithium bromide (the most common commercial desiccant) are fairly expensive, so the project will also look at how long desiccants can be recycled before they have to be replaced.
In the absorption machine, the refrigerant is absorbed in the absorber at its evaporator pressure by an aqueous solution of
lithium bromide.
Bhaduri found that the coefficients of performance (COPs) for all these blends increase with the increase in evaporator and generator temperatures, and that the top-rated blend -- NN Dimethyl acetamide -- has a higher COP than aqua-ammonia and
lithium bromide.
Though each chemical has its advantages and disadvantages, EPA analysis has shown that they can all be used in a safe manner if proper handling procedures are followed," she said, referring to alternatives that include HCFC-123, hydrofluorocarbon (HFC)-134a, HCFC-22, ammonia, and
lithium bromide absorption.
After calculating the efficiency gains from the insulation, glass and sensors, that was reduced to a gas-fired 180 ton
lithium bromide absorption system.
