Abstract
The invention relates to an air conditioning apparatus including a first absorptive heat exchanger having sorption channels in at least one flow direction, a method for conditioning fluids, in particular for cooling and/or drying a stream of air, an adsorptive air-air cross-flow heat exchanger, and an outer wall element including an integrated air conditioning apparatus.
Claims20
A process for conditioning a fluid, which comprises the following steps:
- (a) flow of the process fluid through the sorption channels of a first absorptive heat exchanger,
- (b) drying of the process fluid in the first absorptive heat exchanger,
- (c) flow of the dried process fluid to the cold side of a cold source,
- (d) cooling of the dried process fluid in a cold source,
- (e) flow of the dried and cooled process fluid into the region to be conditioned,
- (f) parallel flow of the regeneration fluid through the heat exchanger channels of the first absorptive heat exchanger,
- (g) uptake of the heat of adsorption by the regeneration fluid,
- (h) flow of the heated regeneration fluid to the hot side of a heat source,
- (i) further heating of the regeneration fluid in the heat source,
- (j) flow of the heated regeneration fluid through the sorption channels of a second absorptive heat exchanger,
- (k) vaporization of the adsorbates located in the second absorptive heat exchanger and uptake of these adsorbates by the regeneration fluid,
- (l) flow of the moist regeneration fluid into an exterior region.
An air conditioning apparatus for conditioning a fluid, comprising
- a first absorptive heat exchanger, which has sorption channels in at least one flow direction and has heat exchanger channels in at least one flow direction,
- a heat-cold source for the removal of heat arranged downstream of the first absorptive heat exchanger in the flow direction of the sorption channels,
- a heat-cold source for the uptake of heat arranged downstream of the first absorptive heat exchanger in the flow direction of the heat exchanger channels and
- a second absorptive heat exchanger, which is arranged downstream of the heat-cold source for the uptake of heat and has sorption channels in at least one flow direction and has heat exchanger channels in at least one flow direction, where the sorption channels on the second heat exchanger are arranged in the flow direction of the heat exchanger channels of the first heat exchanger.
