Lithium Bromide Refrigeration System, LiBr refrigeration system

Hello viewers, Dr. Amit Mandal Here, go through my lucid lecture on lithium bromide refrigeartion systems. Lithium bromide (LiBr) refrigeration is a type of absorption refrigeration that uses lithium bromide as the absorbent and water as the refrigerant. It is a heat-driven refrigeration system, which means that it uses heat to power the refrigeration cycle instead of electricity. LiBr refrigeration systems are typically used in large-scale commercial and industrial applications, such as air conditioning for office buildings, hospitals, and industrial process cooling. They are also used in some solar-powered refrigerators. Here is how a LiBr refrigeration system works: 1)A solution of lithium bromide and water is heated in a generator. This causes the water to evaporate, leaving behind a concentrated solution of lithium bromide. 2)The water vapor travels to a condenser, where it cools and condenses back into a liquid. 3)The liquid water then flows through an expansion valve, which reduces its pressure and causes it to evaporate again. 4)The evaporating water absorbs heat from the surroundings, cooling it down. 5)The cooled water is then pumped to the generator, where the cycle starts again. 6) LiBr refrigeration systems have a number of advantages over conventional vapor compression refrigeration systems, including, they are more energy-efficient, especially when powered by waste heat or renewable energy sources. They are quieter and produce fewer emissions. They are less complex and require less maintenance.
