Abstract

The plant has a generator for a refrigerant in rich solution. A condenser is connected downstream of the generator in the refrigerant loop. A first expansion valve is connected downstream of the condenser. The refrigerant vapor produced there is directed into the sump of an absorber. The liquid refrigerant passes from the first expansion valve to a second expansion valve which adjoins an evaporator. Arranged in the absorber is a jet apparatus, whose nozzle is fed with the weak solution from the generator and whose suction space is connected to the evaporator. The weak solution therefore draws the refrigerant vapor out of the evaporator and delivers it into the top region of the absorber. There, a deflection takes place, whereupon the solution that is increasing in concentration is directed over cooling coils and passes into the sump of the absorber. In this way, very effective droplet, film, trickling and immersion absorption occurs.
