water, combustion gas, etc. flowing in the heat exchanger tubes and a part of water in it is
evaporated to result in increasing its concentration to the original condition. The concentrated
solution flows into the absorber and absorbs the refrigerant vapor again. While, the evaporated
refrigerant vapor flows into the condenser and is cooled down by cooling water running in the heat
exchanger tubes to be condensed and liquefied. The condensed water is supplied to the
evaporator as refrigerant.
As mentioned above, the absorption chiller consisting of the evaporator, absorber, generator and
condenser produces chilled water by latent heat in the process of such change in phase as water
- vapor – water for water and concentrated solution – diluted solution – concentrated solution for
lithium bromide solution, while absorbing the vapor by the lithium bromide solution in the high
vacuum system repeatedly and continuously.
