Adsorbeer-/desorbeerwanntewisselaarAdsorbent / desorbent heat exchanger

De uitvinding heeft betrekking op een adsorbeer/-desorbeerwarmtewisselaar volgens de kop van conclusie 1.The invention relates to an adsorbent / desorbent heat exchanger according to the preamble of claim 1.

5 Bij bekende dergelijke adsorbeer-/desorbeerwarmte- wisselaars is een buis ingebed in granulaat.In known such adsorber / desorber heat exchangers, a tube is embedded in granulate.

Bij dergelijke warmtewisselaars doet zich het nadeel voor, dat door het slechte geleidingsvermogen van het adsorbens en de hoge diffusieweerstand in de storting 10 het sorptieproces slechts heel langzaam en zeer oneffectief verloopt.The disadvantage of such heat exchangers is that the sorption process is very slow and very ineffective due to the poor conductivity of the adsorbent and the high diffusion resistance in the deposit 10.

Doel van de uitvinding is, dit nadeel te vermijden en een adsorbeer-/desorbeerwarmtewisselaar van de in de inleiding genoemde soort te verschaffen, waarbij een snel 15 verloop«van het sorptieproces wordt gegarandeerd.The object of the invention is to avoid this drawback and to provide an adsorber / desorber heat exchanger of the type mentioned in the introduction, whereby a rapid course of the sorption process is guaranteed.

Volgens de uitvinding wordt dit bereikt met een warmtewisselaar van de in de inleiding vermelde soort door de karakteristieke kenmerken van conclusie 1.According to the invention this is achieved with a heat exchanger of the type mentioned in the preamble due to the characteristic features of claim 1.

Door de voorgestelde maatregelen wordt bereikt, 20 dat enerzijds het warmtewisselende oppervlak van de buis wordt vergroot en tussen de afzonderlijke ribben slechts een storting in één laag mogelijk is. Daardoor kan het sorptieproces ondanks het slechte warmtegeleidingsvermogen en ondanks de grote diffusieweerstand van het adsorbens 25 snel en effectief verlopen. Daarbij is een groot stofuitwissel ingsoppervlak voor de adsorptie en desorptie van het adsorbaat, b.v. water, aanwezig en kan de warmte door het directe contact met de ribbe snel met de warmtedrager, die in de buis stroomt, worden uitgewisseld.It is achieved by the proposed measures that on the one hand the heat-exchanging surface of the tube is increased and only one layer is possible to deposit between the individual ribs. Therefore, the sorption process can proceed quickly and effectively despite the poor thermal conductivity and despite the great diffusion resistance of the adsorbent. In addition, a large dust exchange area for the adsorption and desorption of the adsorbate, e.g. water, and the heat can be quickly exchanged by the direct contact with the rib with the heat carrier flowing in the tube.

30 Door de voorgestelde maatregelen wordt ook een hoog warmtegetal van de sorptiewarmtepomp bij gelijktijdig goede vermogensdichtheid bereikt.The proposed measures also achieve a high heat number of the sorption heat pump while at the same time good power density.

In dat verband is het gunstig de kenmerken van conclusie 2 aan te houden.In that regard, it is advantageous to maintain the features of claim 2.

35 Door de kenmerken van conclusie 3 wordt een zeer eenvoudige vervaardiging van een adsorbeer-/desorbeerwarm-tewisselaar volgens de uitvinding mogelijk gemaakt.The features of claim 3 enable a very simple manufacture of an adsorbent / desorbent heat exchanger according to the invention.

De uitvinding wordt nu aan de hand van de teke- 1015112 .The invention is now described with reference to the drawings 1015112.

- 2 - ning, die schematisch een warmtewisselaar volgens de uitvinding toont, nader toegelicht.- 2, which schematically shows a heat exchanger according to the invention, further explained.

De weergegeven adsorbeer~/desorbeerwarmtewisselaar is voorzien van een door een warmteopnemend medium door-5 stroombare buis 1. Deze buis 1 is voorzien van ribben 2 en staat met deze in een goed geleidende verbinding.The shown adsorber / desorber heat exchanger is provided with a pipe 1 which can flow through a heat-absorbing medium. This pipe 1 is provided with ribs 2 and is in a well-conducting connection with it.

Tussen de afzonderlijke ribben 2 is granulaat 4 telkens in één laag aangebracht, waarbij de korrelgrootte van het granulaat iets kleiner is dan de vrije afstand 5 10 tussen twee ribben. Daardoor wordt gegarandeerd, dat er tussen elke twee ribben 2 maar één laag granulaat aanwezig is, waarbij het in het gunstige geval om een zeoliet gaat.Granulate 4 is arranged in one layer between the individual ribs 2, the grain size of the granulate being slightly smaller than the free distance between two ribs. This ensures that there is only one layer of granulate between every two ribs 2, which is advantageously a zeolite.

In het gebied van de ribben 2 is de warmtewisselaar omgeven door een net 3, dat het er uit vallen van het 15 granulaat 4 verhindert. Voor de borging van net 3 is dat omwikkeld met een band 6.In the region of the ribs 2, the heat exchanger is surrounded by a net 3, which prevents the granulate 4 from falling out. To secure net 3, this is wrapped with a band 6.
