Abstract

An absorber and evaporator combination for use with an absorption heat pump (including chillers and air conditioners) as well as with other apparatus in which a vapor is absorbed by a liquid absorbent or a liquid or gas is cooled by evaporative cooling is disclosed. The absorber and evaporator are designed as vertical plates that can receive films of either absorbent (on the absorber) or refrigerant (on the evaporator) flowing down them. A liquid refrigerant is distributed across the top edge of each vertical surface of the evaporator. Likewise, for the absorber, a liquid absorbent is distributed across the top edge of each vertical surface. The distributors for the refrigerant and the absorbent are constructed and arranged so that they distribute their respective liquids without creating droplets. In one embodiment, two vertical evaporator surfaces and two vertical absorber surfaces are assembled into one absorber/evaporator panel. The two evaporator surfaces are positioned facing each other but with a small space between them. The two absorber surfaces are similarly positioned facing each other. A single hollow panel is formed by (1) sealing the two opposed evaporator surfaces al…
