* Lithium Bromide System is another type of absorption refrigeration uses water as refrigerant and lithium bromide as absorbent.
* This System is mainly used for water - chilling purposes.
* Water to be chilled is passed through tubes. Refrigerant water, after expanding in the expansion valve is sprayed over these tubes.
* Because of this, the tube water gets chilled and the refrigerant water becomes water vapor.
* Lithium Bromide solution , which is sprayed in the absorber, absorbs the water vapor. Thus, the solution becomes weak.
* The Weak Solution is pumped to the generator. Here, heating of the solution is done. Because of this, some water evaporates. So, the solution becomes strong.
* This Strong Solution is passed through the heat exchanger and sprayed in the absorber. Thus the cycle repeats.
* Water vapour formed in the generator is passed through a condenser. Water vapor, thus gets condensed and becomes liquid water.
* External supply of cooling water will affect the condenser.
* This cooling water is supplied through the absorber, to carry some heat from there.
* Condensed water (from the condenser) is supplied to the evaporator to make up for the water vapor formed there.
