Method for operating a sorption heat exchanger system and sorption heat exchanger system therefor

摘要

A method for operating an open sorption heat exchanger system (10), in particular an open sorption heat exchanger system (10) for conditioning outside air, with at least two sorption heat exchangers (11a, 11b), the sorption heat exchangers (11) being operated alternately in a conditioning mode of operation and a regeneration mode of operation performing quasi-continuous conditioning of an air stream, and at least partially bringing the air stream into contact with at least one solid desiccant (12), comprising the steps of: • cooling a first sorption heat exchanger (11a) by means of a liquid tempering medium (21) circulated in at least one cycle; drying the desiccant (12), drying and cooling at least one outside air part stream (A) in the first sorption heat exchanger (11a), supplying the dried and cooled outside air part stream (A) as a supply air stream (Z) into one atisierende environment, • further cooling of the supply air flow (Z) by means of one to be discharged from the conditioned environment exhaust air flow (Ab), wherein the supply air flow (Z) standing in thermally conductive exhaust air flow (Ab) to achieve further cooling of the supply air flow (Z) heating a second sorption heat exchanger (11b) by means of a circulating liquid circulating in at least one circulating liquid (22), wherein the desiccant (12) is heated, • regenerating the heated second sorption heat exchanger (11b), wherein a by the heating of the desiccant (12) released water vapor from an outside air partial stream (A) and is continued as exhaust air flow (F), and • cooling the temperature control (21) in a wet cooling tower (23) by means of the exhaust air flow (Ab), wherein the operating modes of Sorptionswärmetau shear (11a, 11b) in phases.
