効率良く蒸発、凝縮できる。Effect In the above configuration, water flash evaporates in the evaporator and becomes water vapor, and this water vapor is transferred to the absorber.
The diluted liquid is absorbed into the LiBr-H 2 O system solution and diluted by absorbing water vapor in the absorber. The diluted liquid is heated in the regenerator to evaporate the water, and the water vapor generated in the regenerator is injected in the condenser. Because the refrigerant is condensed by direct contact with water, it is able to efficiently evaporate and condense water (refrigerant) despite its small size and simple structure.
