Humidity/heat-exchange device

Abstract

A moisture and / or heat exchange device, such as a flat plate heat exchanger, moisture absorption drum, sorption desiccant drum, etc., having moisture or heat exchange surfaces by means of which moisture and / or Heat can be introduced into and / or taken away from fluid streams, and / or moisture and / or heat can be exchanged between fluid streams, and it has a coating, wet or heat exchange surface coated with The coating is composed of zeolite material and binder. In order to increase the efficiency of wet and / or heat exchange devices of this type, it is proposed to use a synthetic nano-zeolite as zeolite material, which consists of particles with a particle size of <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.
