Humidity/heat-exchange device e.g. plate heat exchanger, hygroscopic drum, adsorption damp-clearing dump or the like device

Abstract

The invention relates to a humidity- and / or heat-exchange device, for example a plate heat exchanger a sorption rotor, an adsorption dehumidifying rotor or the similar, provided with humidity- and / or heat-exchange surfaces which make it possible to introduce humidity and / or heat into a fluid flow and / or to remove them therefrom and / or to exchange said humidity and / or heat between fluid flows. The inventive device is also provided with a coating, which makes it possible to cover said humidity and heat exchange surfaces and consists of a zeolithe material and a bonding agent. In order to improve the performance of the humidity- and / or heat-exchange device, the zeolithe material is embodied in the form of a synthetic nano-zeolithe consisting of particles whose size is < 1000 nm.

Description

technical field [0001] The present invention relates to a moisture and / or heat exchange device, such as a flat plate heat exchanger, a moisture absorption drum, an adsorption desiccant drum, etc., which have a moisture or heat exchange surface by means of which moisture and / or heat can be introduced into and / or taken away from the fluid streams, and / or moisture and / or heat can be exchanged between the fluid streams, and they have a coating, wet or heat exchange surface Apply this coating, which consists of a zeolite material and a binder. Background technique [0002] Moisture and / or heat exchange devices of this type are often used for temperature and air conditioning of rooms. Furthermore, this type of moisture and / or heat exchange device can also be used for other industrial purposes. [0003] From the state of the art, known moisture and / or heat exchange devices of this type (especially when removing moisture from a fluid flow or humidifying a fluid flow with moisture...

AI Technical Summary

Problems solved by technology

[0003] From the state of the art, known moisture and / or heat exchange devices of this type (especially when removing moisture from a fluid flow or humidifying a fluid flow with moisture) have the disadvantage that, Adsorption processes and / or desorption processes, one or both of which take place in a moisture and / or heat exchange device, which require an excessively long time, whereby this type of moisture and / or heat exchange device in itself cannot realize its possible productive capacity

In addition, the coated surfaces subjected to the fluid flow often have roughness, as a result of which particles contained in the fluid flow can accumulate thereon, which leads to a considerable loss of efficiency of the corresponding device or often necessitates expensive cleaning and maintenance measures

In addition, there is often the difficulty of affixing the coating to the material forming the skeleton or matrix of the moisture and / or heat exchanging device.
