Abstract

A moisture and/or heat exchange device, for example a plate heat exchanger, a sorption rotor, adsorption dehumidifying rotor or the like, has moisture or heat exchange surfaces, by means of which moisture and/or heat can be introduced into a stream of fluid and/or can be extracted from a stream of fluid and/or can be exchanged between streams of fluid, and a coating, with which the moisture or heat exchange surfaces are coated and which contains a binder and a nano zeolite with a particle size of <1000 nm. In order to ensure permanent attachment of the applied coating, it is proposed that the binder is a polyurethane resin.

Claims

exact text as granted — not AI-modified
1 . a plate-type moisture or heat exchanger, a sorption rotor, or an adsorption dehumidification rotor, having moisture or heat-exchange surfaces that can transfer moisture or heat into a fluid flow or extract moisture or heat from a fluid stream or transfer moisture or heat between fluid streams, a coating on the moisture or heat exchange surfaces and that contains polyurethane resin as a binding agent and nano-zeolite particles with a particle size<1000 nm. 
     
     
         2 . The moisture or heat exchanger according to  claim 1 , wherein the coating of nano-zeolite particles in polyurethane has a homogeneous pore size distribution with a pore diameter<1.5 nm. 
     
     
         3 . The moisture or heat exchanger according to  claim 1 , wherein the particles of nano-zeolite are in nano-crystalline form. 
     
     
         4 . The moisture or heat exchanger according to  claim 1 , wherein the thickness of the coating is between 0.2 and 100. 
     
     
         5 . The moisture or heat exchanger according to  claim 1 , wherein the moisture or heat exchange surfaces are made of aluminum, other suitable metallic or ceramic materials, plastics or paper. 
     
     
         6 . The moisture or heat exchanger according to  claim 1 , wherein the coating of the nano-zeolite and the polyurethane resin is applied to an unprimed aluminum surface or one that has not undergone holding primer-forming measures. 
     
     
         7 . The moisture or heat exchanger according to  claim 1 , wherein the binding agent is a polyester-based polyurethane resin.
