High-Customized Hot Water LiBr Absorption Chiller

Hot water-type Libr absorption chiller is a hot water-powered refrigeration unit.
It adpots the aqueous solution of lithium bromide(Libr) as a cycling working medium.
The LiBr solution works as an absorbent and water as a refrigerant.

The chiller comprises primarily the generator,condenser,evaporator,absorber,

heat exchanger,automatic extractor,burner,vacuum pump and canned pump.

Working principle:The refrigerant water in the evaporator evaporates away

from the surface of the heat conducting tube.As heat in the chilled water

is taken away from the tube,the water temperature drops and quantities of

cooling are generated. The refrigerant steam evaporated from the evaporator

is absorbed by the thick solution in the absorber and therefore the solution is

diluted.The thin solution in the absorber is then delivered by the solution pump

to the heat exhanger ,where the solution is heated and the solution temperature

rises.Then the thin solution is delivered to the generator,where it is heated by

hot water to produce refrigerant steam.Then the solution becomes a thick solution.

After releasing heat in the heat exchanger,the temperature of the thick solution drops.

The thick solution then enters the absorber,where it absorbs the refrigerant steam

from the evaporator,becomes a thin solution and enters the next cycle.The

refrigerant steam generated by the generator is cooled in the condenser to form

refrigerant water,which is further depressurized by a throttle vavle and delivered to

the evaporator.After the evaporation& refrigeration process,the refrigerant steam

enters the next cycle.

The aforesaied cycle occures repeateedly to form a continuous refrigeration process.
