10 237765 PŘEDMĚT VYNÁLEZU t. Způsob regenerace tepla a ekonomie chladicí vody při abaorbci snadno absorbovatel-ných plynů nebo par kapalinou, provázené oddělením absorbčního tepla, při regeneračnímvyužití podle možnosti největší části absorbčního teple, při použití zavlažovaných ab-sorbentů, vyznačující se tím, že nasycovaný zředěný roztok 1 se dělí na dva dílčí proudy,které paralelně jeden k druhému procházejí absorbérem 3 a absorbér dílčího proudu 2, kterýje přitom známým způsobem obohacován pracovním prostředím (6), a dílčí proud roztoku,vycházející z absorbéru dílčího proudu (2) se znovu mísí se základním proudem vySSl kon-centrace a společný proud koncentrovaného roztoku (5) se potom přivádí do absorbéru dílčíhoproudu (2) jako chladicí prostředí, přičemž oba absorbéry (3, 2) pracují známým způsobem,v režimu zpětného proudu nebo v podobném režimu.
2. Způsob podle bodu 1, vyznačující setím, že dílčí proud koncentrovaného roztoku,opouštějící absorbér dílčího proudu (2) se opět směSuje se základním proudem v absorbéru (3) před posledním prvkem absorbéru (3, 4).
