DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings shown in FIGS.
1 shows an embodiment of a ventilation system at the time of a humidifying operation of a humidity control device according to the present invention, and reference numeral 1 denotes a rotary humidity control element incorporated in a case main body 100 installed on the indoor side of a side wall W, for example. Therefore, for example, a metal silicate gel combining silica, cobalt, iron, manganese, and other metals is polymerized into a ceramic honeycomb laminate, and the micropore shape is fine-tuned to match water molecules. And by increasing the number of hydroxyl groups in the micropores to increase the hydrophilicity,
At room temperature, it adsorbs moisture well, and when the temperature rises to 130 to 140 ° C., the adsorbed moisture is released, and in this case, it has a cylindrical shape, and the diameter of the cylinder is, for example, At 20 cm, it is controlled so as to make, for example, 1/2 rotation per minute.

[0009] The rotary humidity control element 1 has a drying function part 2 which has a function of passing low-temperature air taken in from the outside and adsorbing and removing moisture contained in the air.
And a humidifying function section 3 for passing the air whose temperature has risen due to the heat treatment, giving moisture to the air, moistening and recovering the function of adsorbing moisture, and a low-temperature air taken from outside the machine. It is divided into a heat recovery function part 4 which has a function of increasing the temperature of the passing air by lowering the temperature of the rotary humidity control element 1 while passing through the temperature-raised part.

The drying function part 2, the humidification function part 3, and the heat recovery function part 4 are partitioned, for example, in an area ratio of 3: 1: 1, and the drying function part 2 and the humidification function part 3 (the heat recovery function part 4). ) Is, for example, 80 (m ³ / h): 30.
(M ³ / h), and X indicates the rotation direction of the rotary humidity control element 1.

In the case body 100, an outdoor R1 is provided.
A first air passage 5 is formed such that the outside air A on the side passes through the drying function part 2 of the rotary humidity control element 1, and an upstream side 5A of the first air passage 5 with respect to the drying function part 2 includes: A first push-type blower 10 is provided.

The first push-type blower 10 takes in the outside air A on the outdoor R1 side from the intake port W1 opened in the side wall W of the upstream side 5A of the first ventilation path 5 by the pushing action, and performs a drying function. While passing through the portion 2, moisture is adsorbed to dry the outside air A, and the dried dry air B is dried by the first air.
Exhaust port W2 opened on the side wall W of the downstream side 5B of the ventilation path 5 of FIG.
From the outside to the outdoor R1 side.

In the case body 100, a room R2 is provided.
Side indoor air C is the heat recovery function part 4 of the rotary humidity control element 1.
Is formed, and a second air passage 6 passing through the second air passage 6 is formed.
Has a path that is U-turned after passing through the heat recovery function part 4, passes through the humidification function part 3, and reaches the room R2 side, and has an upstream side 6A with respect to the heat recovery function part 4. , A second push-type blower 20 is provided.

The second push-in type blower 20 takes in the room air C by the pushing action, and performs the heat recovery process from the rotary humidity control element 1 through the heat recovery function portion 4. On the other hand, the heat recovery air D after the heat recovery processing that has passed through the heat recovery function part 4 is heated by an electric heater 7 as a heating means, and the heated high-temperature air E is heated.
Is taken in so as to pass through the humidifying function part 3 to wet the room air C by separating and releasing the moisture adsorbed by the rotary humidity control element 1 and to recover the moisture adsorbability of the rotary humidity control element 1. The humidified air F thus humidified is discharged to the room R2, and the room R2 is humidified.

FIG. 2 shows an embodiment of the blower system at the time of the dehumidifying operation.
At the same time, the air passage is switched so that the room air C taken in from the room R2 side passes through the drying function part 2 and the dehumidification and drying can be achieved, and the dried air B dried by passing through the drying function part 2 is While the ventilation path is switched so as to be discharged to the indoor R2 side, the outdoor R
The air passage is switched so that the outside air A taken in from the first side passes through the heat recovery function part 4, and the high-temperature air E passed through the heat recovery function part 4 and heated by the electric heater 7 passes through the humidification function part 3. The ventilation path is switched so that moisture is removed from the rotary humidity control element 1 to recover the moisture adsorbing property of the part and the wet air F is discharged to the outdoor R1 side.

FIG. 3 shows an embodiment of a blower system at the time of a ventilation operation which is performed in a state where the heating action by the electric heater 7 is stopped, and a second push-in type blower 20 is shown.
At the same time, the air passage is switched so that the room air C taken in from the room R2 passes through the drying function part 2, and the moisture passing through the drying function part 2 is not deprived of the adsorbed moisture by the humidification function part 3, Therefore, since the moisture adsorbing property of the drying function part 2 has not been restored, the ventilation path is switched so as to discharge the apparent dry air Bm having almost no change in humidity to the outdoor R1 side, while the first push-in operation is performed. The ventilation path was switched so that the outside air A taken in from the outdoor R1 side by the mold blower 10 passed through the heat recovery function part 4, and passed through the humidification function part 3 following the heat recovery function part 4, but the temperature increased. Since there is no air passage, the ventilation path is switched so that the apparent humid air Fm having almost no change in humidity is discharged to the room R2 side.

Since the outside air A and the room air C are ventilated with heat exchange, the heat efficiency is good when heating or cooling is performed in the room R2. For example, during the heating operation in which the room air C is higher than the outside air A, the temperature of the rotary humidity control element 1 passes through the drying function part 2 due to the passage of the room air C taken in by the second push-type blower 20. The outside air A having a low temperature taken in by the first push-type blower 10 passes through the heat recovery function part 4 and the humidification function part 3 in this order, and the temperature rises. Since the air is discharged to the R2 side, ventilation with reduced temperature loss is possible, and energy saving during the cooling / heating operation can be achieved.

[0018]

As described above, according to the humidity control apparatus of the present invention, the functions of dehumidification, humidification, and ventilation are performed by using one rotary humidity control element, so that the apparatus has three types of functions. However, it can be realized with a simple configuration and can be downsized. In addition, drain water is not generated even when dehumidification is performed, and there is no need to prepare water during humidification, so that the usability is good.
