As shown in FIG. 2, this device is composed of an air path switching section 5, an adsorbent 1 and a heater 2, a blower 3, and an air path switching section 4 in order from the top. The air path can be switched.

とにより乾式加湿がおこなわれる。In the above configuration, when humidification is performed, the air path switching section 4 is set to open to the outside of the room, allow outdoor air to pass through the adsorbent 1, and then return to the outside of the room via the air path switching section 5 again. The moisture of the outdoor air is adsorbed by the adsorbent 1. Thereafter, the air path switching units 4 and 5 are set so as to close the air path on the outdoor side, so that the indoor air passes through the adsorbent 1 and returns to the indoor area again. At this time, the indoor air is heated by the heater 2,
When the adsorbent 1 passes through the adsorbent 1, the adsorbent 1 is heated to desorb the adsorbed moisture, and this moisture is supplied to the room to perform dry humidification.

Heat exchange loss when the air for regeneration is heated by the heater 2,
There are heat loss when the hot air passes through the air passage, heat loss when the hot air heats the adsorbent 1, and the like. For this reason, energy consumption increased, the running cost (approximately 10 times higher than the ultrasonic method) was higher than other humidifying methods, and the price was not competitive. Furthermore, since the adsorbent 1 is indirectly heated, the regeneration time becomes long. Therefore, the adsorption operation and the regeneration operation are performed alternately, so that the humidification capacity is affected by the regeneration time, and the humidification performance cannot be sufficiently exhibited. In order to guarantee the capacity, it is necessary to increase the amount of the adsorbent 1.

る。The operation of humidification will be described based on the above configuration. The control unit 11 starts from the suction operation.
(Although the adsorbent 1 has moisture adsorbed by diffusion, it first starts with the adsorption operation in order to adsorb it to the vicinity of the saturated adsorption amount. Therefore, the first adsorption operation time is shorter than the subsequent adsorption operation time. The air supply port switching unit 9 and the exhaust switching unit 10 block the indoor side. The blower 3 starts operating, supplies outdoor air to the adsorbent 1 from the outdoor air supply port 5, and adsorbs moisture. The dried indoor air is exhausted from the outdoor exhaust port 6. When the adsorbent 1 is in a breakthrough state, the control unit 11 stops the operation of the blower 3 and the air supply switching unit 9 and the exhaust switching unit 10 close the outdoor side. Thereafter, the control unit 11 causes the heating source 2 to be energized to heat the adsorbent 1. The indoor air from the indoor air supply port 7 passes through the adsorbent 1 which has reached the regeneration temperature by heating and has started to desorb water, receives the water, and is supplied into the room. The room is humidified by repeating the above-mentioned adsorption operation-regeneration operation.

下の問題は、以下の加湿換気により、解決できる。During this operation, since the heating source 2 directly heats the adsorbent 1, energy-saving humidification with very little heat loss can be performed. However, at this point, the room can be humidified, but the nitrogen outside the room that has been adsorbed by the adsorbent 1 is also released into the room, so that the oxygen concentration in the room decreases. The problem of the decrease in the oxygen concentration can be solved by the following humidification ventilation.

ことは言うまでもない。Next, humidification ventilation will be described. At the time of humidification ventilation, the control unit 11 starts from the suction operation. The air supply switching unit 9 closes the outdoor side, and the exhaust switching unit 10
Closes the indoor side. The blower 3 starts operating, supplies indoor air to the adsorbent 1 from the indoor air supply port 7, and adsorbs moisture. The dried indoor air is exhausted from the outdoor exhaust port 6. When the adsorbent 1 is in a breakthrough state, the control unit 11 stops the operation of the blower 3, the air supply switching unit 9 blocks the indoor side, and the exhaust switching unit 10 blocks the outdoor side. Then, the control unit 11 supplies a current to the heating source 2 to heat the adsorbent 1. After the outdoor air passes through the charging filter 4 through the outdoor air supply port 5, the air passes through the adsorbent 1 which has reached the regeneration temperature by heating and has started to desorb water, and is supplied into the room together with the water. By repeating the above-mentioned adsorption operation-regeneration operation, humidification ventilation is performed. During this operation, since the heating source 2 directly heats the adsorbent 1, energy-saving humidification and ventilation with very little heat loss can be performed, and at the same time, NO X can be increased without increasing the indoor humidity and lowering the oxygen concentration. , CO 2 ,
It has the effect of reducing CO, odor components and the like. After all the operations are completed, the control unit 11 prevents the air supply switching unit 9 and the exhaust switching unit 10 from closing the outdoor side, and prevents the outdoor air from flowing into the room when not in use. Needless to say.
