Výmeník tepla s cástecnou absorpcí a desorpcí par, který je tvoren dutým pláštem (1), jehož vnitrní prostor je v podstate vertikálne situovanou delící stenou (2) rozdelen na desorpcní kanál (3) a absorpcní kanál (4), kde jednak desorpcní kanál (3) je v oblasti dna (101) plášte (1) opatren prívodním hrdlem (31) chladivem nasyceného roztoku a v oblasti horní steny (102) plášte (1) odvodním hrdlem (32) ochlazeného roztoku a jednak absorpcní kanál (4) je v oblasti horní steny (102) plášte (1) opatren vstupním hrdlem (41) chladivem nenasyceného roztoku a v oblasti dna (101) plášte (1) výstupním hrdlem (42) ohrátého roztoku. V desorpcním kanálu (3) i absorpcním kanálu (4) jsou na v podstate stejné horizontální úrovni zabudovány sekce smerem dolu otevrených dvojic vestaveb (5), tvorených smerem dolu otevrenými dutými profily, které jsou vzájemne propojeny prevodními kanály (6) a jsou usporádány v každém z kanálu (3, 4) nad sebou tak, že vytvárejí labyrintové protismerné pruchody pro proudící chlazené i ohrívané médium. The invented heat-exchange apparatus with partial absorption and desorption of fumes is formed by a hollow jacket (1), the interior of which is separated by a substantially vertically situated partition wall (2) into a desorption channel (3) and an absorption channel (4), wherein said desorption channel (3) is provided in the jacket (1) bottom (101) area with an inlet branch (31) of a coolant-saturated solution and in the region of the jacket (1) upper wall (102) with an outlet branch (32) of a cooled solution, while said absorption channel (4) is provided in the jacket (1) upper wall (102) region with an inlet branch (41) of the coolant-unsaturated solution and in the jacket (1) bottom (101) area with an outlet branch (42) of a warmed solution. In both, the desorption channel (3) and the absorption channel (4), there are integrated at substantially identical horizontal level sections of downward open pairs of arrangements (5) formed by downward open hollow sections, which are interconnected by by-pass channels (6) and arranged in each channel (3, 4) one above the another such that they form labyrinth-like counter-passages for both flowing cooled and heated medium.
