本発明は空気の湿度を低下させる除湿方法あるいは空気

技術に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a dehumidifying method for lowering the humidity of air or a method for drying air, and mainly relates to a technology for a dehumidifying method for air conditioning.

の方法が多方向に開発され、実用化されている。(Prior Art) As conventional dehumidification/drying methods, methods of adsorption dehumidification using porous materials such as lilac gel or absorption dehumidification using lycheam chloride have been developed in many directions and put into practical use.

る。(Problems to be Solved by the Invention) In this conventional adsorption/absorption dehumidification method, the moisture absorption power depends on the relative humidity of the air of the moisture absorption fluid, and the higher the relative humidity, the faster the moisture absorption rate. However, as moisture in the air is adsorbed and absorbed, the relative humidity drops by 1 degree Celsius, and the rate of moisture absorption slows down.

まって空気の相対湿度は激減し、吸着・吸収材の吸湿効
果が大巾に低下して除湿率に限界ができる。On the other hand, when moisture in the air condenses, it produces approximately 600Kca.
The latent heat of condensation of l/kg water is generated and increases the air temperature. Therefore, when moisture in the air condenses, combined with dehumidification, the relative humidity of the air decreases dramatically, and the moisture absorption effect of the adsorbent/absorbent material decreases significantly, putting a limit on the dehumidification rate.

A hygroscopic material that has hygroscopicity and recovers its hygroscopicity by discharging moisture when heated is provided in the air passage so as to be in good contact with the processing air, and the processing air to be dehumidified is continuously supplied to the air passage. At the same time as the refrigerant is being fed, a low-temperature fluid such as cold air is sent into the air path to cool the air in the air path, while a dehumidification process is performed in which moisture is absorbed and absorbed by the moisture absorption surface.After that, heated air is sent into the air path to adsorb moisture from the moisture absorption surface. The dehumidification method is characterized in that the humidity of the air is lowered by performing a heating regeneration step in which the moisture is discharged, and by repeating the dehumidification step and the heating regeneration step alternately.

効果的に行える。(Function) In this invention, highly humid treated air is continuously sent to the air path, and at the same time, low-temperature air or another fluid serving as a refrigerant is sent to the refrigerant path. A partition plate that partitions the refrigerant path and the air path is cooled, and the air within the air path is cooled. This cooling can be effectively achieved by the refrigerant passage and the air passage being arranged in multiple layers alternately.

、吸湿されても相対湿度は大ぎく下がることがなく引き
続いて処理空気の水分は吸湿面に吸着・吸収され吸湿効
果の低下はなく、高い除湿率まで除湿される。The processed air sent to the air path comes into contact with the moisture absorbing surface inside the air path and absorbs moisture, thereby reducing the humidity. In addition, the temperature of the treated air in the air path decreases as it is cooled by the refrigerant path, so even if moisture is absorbed, the relative humidity does not drop significantly, and the moisture in the treated air is subsequently adsorbed and absorbed by the moisture absorption surface, resulting in a moisture absorption effect. There is no decrease in humidity, and dehumidification is achieved to a high dehumidification rate.

非連続的に低湿度まで除湿することができる。If heated air is sent into the air passage after the moisture absorption process in which the moisture absorption surface adsorbs and absorbs moisture, the heated air heats the moisture absorption surface and expels the moisture that has been adsorbed and absorbed up to that point. The exhaled moisture is discharged to the outside together with the heated air. This heating regeneration process allows the moisture absorbing surface to be reused and prevents the moisture absorption effect from decreasing in the next dehumidification process. By repeating the above dehumidification process and heating regeneration process, air can be continuously or discontinuously dehumidified to a low humidity level.
