Lithium bromide air conditioning

Lithium bromide air conditioning, known as lithium bromide absorption refrigerator, is a kind of air conditioning system driven by heat energy, through lithium bromide solution as absorber, water as refrigerant for refrigeration. Its working principle is mainly based on the absorption refrigeration cycle, different from the traditional compression air conditioning through the motor drive compressor to achieve refrigeration.

Four basic steps of the working process of lithium bromide air conditioning:

Absorption process: under high temperature and high pressure, the lithium bromide solution in the dilute solution absorbs the heat from the water vapor in the evaporator, and the water vapor is absorbed into a concentrated solution, releasing the cold volume.

Desorption process: the concentrated solution is sent to the high pressure generator, heated by the external heat source (such as gas, steam, hot water, solar energy, industrial waste heat, etc.), and the lithium bromide solution decomposes to release high purity water steam.

Condensation process: the released water steam is condensed into liquid water in the condenser, and releases a large amount of cooling volume, which is cooled by cooling water or directly through the air, and finally transported to the indoor unit to provide cooling air for the indoor air.

Concentration process: The condensed water flows into the absorber and miwith the dilute solution to regenerate a low concentration of lithium bromide solution, which is sent back to the evaporator to start a new refrigeration cycle.

Characteristics and advantages of lithium bromide air conditioning:

Efficient use of energy: a variety of waste heat, low grade heat source can be used as driving energy, energy saving effect is remarkable.

Low operating costs: where there is sufficient waste heat or cheap energy, operating costs are lower than conventional electric drive air conditioners.

Environmental protection: no harmful substances discharge, environment-friendly.

Smooth operation: low noise,low vibration, suitable for noise and vibration have strict requirements of the place.

Lithium bromide absorption refrigeration unit can be divided into: direct combustion gas type lithium bromide unit, steam (hot water) type lithium bromide unit two kinds.
