Abstract (en)

[origin: CA2763417A1] The present invention relates to an ammonia-water absorption refrigeration unit (1) for operating temperatures even below 100°C, comprising at least one absorber (10) arranged in a coolant circuit (2), wherein the absorber (10) comprises a fully welded plate packet for an inner medium, which plate packet in turn is arranged in a jacket tube for an outer medium. The invention further relates to a method of minimal complexity for conducting media in at least one coolant circuit (2) of an ammonia-water absorption refrigeration unit (1) according to the invention, using heat exchangers which comprise a fully welded plate packet for an inner medium, which plate packet in turn is arranged in a jacket tube for an outer medium. The invention further relates to the use of an optimized absorber (10) according to the invention, comprising a fully welded plate packet for an inner medium, which plate packet in turn is arranged in a jacket tube for an outer medium, in a coolant circuit (2) of an ammonia-water absorption refrigeration unit (1) according to the invention.
