Abstract:
The object of the present invention is to provide an excellent total heat exchanging element paper and a total heat exchanging element which are excellent in heat transferability, water vapor permeability and gas barrier properties and cause no mixing of supplied air and discharged air. The present invention provides a total heat exchanging element paper using a paper made using mainly a natural pulp beaten to a Canadian modification freeness of not more than 150 ml, a substantially non-porous total heat exchanging element paper comprising a substantially non-porous cellulosic base which contains a moisture absorbing agent, a non-porous total heat exchanging element paper having a high gas barrier property which has a thickness of not more than 100 μm and a carbon dioxide permeation constant specified in JIS K7126 of not more than 5.0×10−13 mol·m/m2·s·Pa, and a non-porous total heat exchanging element paper having a high enthalpy exchangeability which has a water vapor permeability specified in JIS Z0208 of not less than 1000 g/m2·24 Hr at 20° C. and 65% RH.

A dehumidifying element includes a super absorbing polymer (SAP), and a hygroscopic base, thereby maintaining hygroscopic characteristics regardless of aging and a high humidity absorbing rate and needing a smaller amount of energy for regeneration.
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
Abstract:
The present invention provides an adsorbent for adsorption heat pump and humidity-control air conditioner, which is capable of adsorbing an adsorbate therein and desorbing the adsorbate therefrom in a narrow relative vapor pressure range, and can be regenerated (desorption) at a low temperature. Also, the present invention provides an adsorption heat pump and humidity-control air conditioner using the adsorbent which can be effectively operated even by a low-temperature heat source, as well as methods of operating the adsorption heat pump and humidity-control air conditioner by effectively utilizing low-temperature exhaust heat. The absorbent of the present invention comprises zeolite containing (i) aluminum, (ii) phosphorus and (iii) iron and/or gallium in a skeletal structure thereof, which is substantially free from change in structure upon subjecting the adsorbent to adsorption and desorption of water vapor.
