Evaporator and adiabatic flat sheet absorber assembly. An absorption machine is described that has an evaporator and an absorber in the same container. In said absorber, the lithium bromide solution is sprayed in the form of a flat sheet and without heat exchange (adiabatic). The heat transfer is carried out in another heat exchanger, which can be dissolution-air or solution-water. (Machine-translation by Google Translate, not legally binding)
