摘要:
As conventional heat exchange modules, adsorptive agents of an inorganic type such as silica gel, zeolite, active alumina, active carbon and molecular sieve have been used. While these adsorptive agents have characteristics of high moisture absorptive ability and easy handling, they have problems of durability, regenerating temperature and generation of bacteria or fungi. An object of the present invention is to solve these problems which are noted in the inorganic adsorptive agents and to provide a heat exchanger module of a energy conservation type having a high heat exchange efficiency and a method for the manufacture thereof. The present invention is a heat exchange module of a sorptive type, characterized in that , a moisture absorptive layer in which a sorptive agent of an organic polymer type comprising organic polymer having hydrophilic polar group and cross-linking structure in a molecule is an essential component, saturated moisture absorbing rates at 20°C and 65% RH and 90% RH are not less than 20% by weight and not less than 40% by weight, respectively and the difference in the saturated moisture absorbing rates under such a condition is not less than 20% by weight is formed on a metal surface having excellent heat conductivity.

The present invention provides a moisture absorptive and dischargeable cloth comprising a hydrophobic synthetic fiber in a proportion of not less than 60 wt%, and moisture highly absorptive and dischargeable organic fine particles comprising an acrylic polymer having a crosslinking structure and a carboxyl group in a salt form, wherein the organic fine particles are bonded to the surface of the fiber by graft polymerization. The moisture absorptive and dischargeable cloth of the present invention shows extremely high moisture absorption as compared to an unprocessed cloth, and shows superior moisture absorption-heat generation-temperature rise property and moisture absorption-heat generation/moisture discharge-cooling property. When the cloth of the present invention is used for clothings, it quickly absorbs moisture and heat in the clothings and discharges them into the air, thus controlling the weather within clothings, as a result of which sweatiness and stickiness are reduced and a smooth touch is afforded. In addition, since it is superior in resistance to washing and resistance to friction, the moisture absorption and discharge property can be maintained for a long time.

A compact and energy efficient air conditioning system is operated with a desiccant material having a high differential adsorption capacity even at lower regeneration temperatures than those in the conventional system. The desiccant assisted air conditioning system comprises a process air path (A) for flowing process air to adsorb moisture from the process air by a desiccant member, and a regeneration air path (B) for flowing regeneration air heated by a heat source to desorb moisture from the desiccant member (103). The desiccant member is arranged so that the process air or the regeneration air flows alternatingly through the desiccant member. The desiccant member comprises an organic polymer material, the organic polymer material comprising an amphoteric ion exchange polymer having an anion exchange group, a cation exchange group and bridging ligands, thereby exhibiting a high differential adsorption capacity.
摘要:
The conventional crosslinked acrylic acid fiber has such characteristics that the harmonic functions such as pH buffer property, antistatic property and water-holding property and also high moisture-absorption rate, high moisture-absorption velocity, high moisture-absorption rate difference or temperature adjusting and humidity adjusting functions derived therefrom, but there is still a problem for its dyeing property. The present invention provides a fiber having the above characteristics and making a practical dyeing with an acid dye possible. To be more specific, the present invention provides a moisture-absorptive fiber dyeable with an acid dye, comprising a region of a polymer having a functional group acting as a dyeing site for acid dye and a region of a polymer having a crosslinked structure and a carboxyl group, wherein the saturation dye uptake of the acid dye to the fiber weight is 3.5 to 10% by weight and the carboxyl group content is 1.0 to 10 mmol/g.
