Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem wherein when an adsorbing element is cylindrical, only a small-sized adsorbing element can not be mounted for its space. <P>SOLUTION: First and second adsorbing elements 1, 2 can move reciprocally linearly between a first position and a second position. A heater 12 is disposed in a second air passage, and when the first adsorbing element 1 is located in the first position, the second adsorbing element 2 is located in the second position, so that the first adsorbing element 1 adsorbs moisture from the air, and the second adsorbing element 2 desorbs moisture to the air. When the first adsorbing element 1 is located in the second position, the second adsorbing element 2 is located in the first position, so that the first adsorbing element 1 desorbs moisture to the air, and the second adsorbing element 2 adsorbs moisture from the air. Thus, the adsorbing elements are linearly moved so that the form of the whole humidity controller including a moving locus is substantially rectangular. Accordingly, it is possible to achieve the humidity controller loaded with a larger adsorbing element as compared with the conventional substantially cylindrical humidity controlling element using a rotary type adsorbing element. <P>COPYRIGHT: (C)2009,JPO&INPIT

  Next, the operation of the humidity control apparatus according to the first embodiment will be described with reference to FIG. FIG. 2 is a cross-sectional view of the housing 5 viewed from the right side in FIG. 1, with the left half being the adsorption zone 6 and the right half being the desorption zone 7.

  In FIG. 2A, the first adsorption element 1 is located in the adsorption zone 6, and the second adsorption element 2 is located in the desorption zone 7. At this time, the outdoor air A that has entered from the outdoor air intake port 8 is dehumidified by adsorbing moisture when passing through the first adsorption element 1.

  Inside the housing 5, the first adsorbing element 1 and the second adsorbing element 2 are configured to be able to reciprocate linearly in the front and back directions in the figure. Although not shown in the figure for the sake of simplicity, rails for guiding the movement of the two adsorption elements 1 and 2 are provided on the inner surface of the housing 5, while racks are provided on the respective side walls of the adsorption elements 1 and 2. By providing an adsorption element drive motor having a gear corresponding to this, it is possible to linearly reciprocate the adsorption elements 1 and 2 in the front and back directions in the figure.

  Next, the operation of the humidity control apparatus according to the second embodiment will be described with reference to FIG. 4 is a cross-sectional view of the housing 5 as viewed from the right side in FIG. 3. The left half is the adsorption zone 6 and the right half is the desorption zone 7. The dehumidified air exhaust port 9 in the adsorption zone 6 and the outdoor air intake port 10 in the desorption zone 7 are on the front side in FIG.

  In FIG. 4A, the first adsorption element 1 is located in the adsorption zone 6 and the second adsorption element 2 is located in the desorption zone 7. At this time, the outdoor air A that has entered from the outdoor air intake port 8 is dehumidified by adsorbing moisture when passing through the first adsorption element 1. The dehumidified air reaches the room along the first air flow path 3 through the dehumidified air exhaust port 9, the second blower 14, the air supply duct 19, and the wall through hole 20.

Similarly, for example, the adsorption element driving motor is driven at regular intervals of, for example, 30 seconds to 5 minutes, so that the two adsorption elements 1 and 2 are moved in opposite directions. By reciprocating, the air that has been dehumidified and reduced in moisture always passes through the second blower 14, passes through the wall through the air supply duct 19, and is exhausted indoors, thereby reducing the indoor humidity.

  As described above, according to the second embodiment of the present invention, since the adsorption element moves linearly, the entire humidity control apparatus including the movement trajectory has a substantially rectangular parallelepiped shape. Compared to a roughly cylindrical humidity control element that uses a rotor-type adsorption element, it is easier to store in a substantially rectangular parallelepiped storage space, and it is possible to mount a larger adsorption element using the space effectively.
