Dehumidified air is blown indoors.

As described above, according to the dehumidifying apparatus of the first embodiment of the present invention, when moisture in the air is absorbed by the moisture absorbing element 1, the network structure of the super absorbent polymer physically expands,
Since moisture is retained in the space, there is no generation of heat of adsorption that occurs when ordinary silica gel adsorbs water,
Since the temperature rise is very small at about 1 to 2 ° C., dehumidified air with a small air conditioning load can be supplied indoors. FIG. 2 shows the amount of dehumidification by the water absorbing element 1. The water absorbing element 1 can absorb 1 g of water per 1 g.

The dehumidified air is sent to the room by allowing the moisture absorbing element 1 to absorb the moisture in the high-humidity air in the room by the blower 6 which also serves as the processing and regeneration. When the moisture absorption element 1 becomes saturated with water and the dehumidification performance deteriorates, the air blown from the processing / regeneration and blower 6 is heated by the heater 7 to a temperature of 50 to 70 ° C., and the heated air is kept for 5 to 10 minutes. By sending air to the moisture absorbing element 1, the moisture absorbing element 1 is regenerated.

The dry air dehumidified by the moisture absorbing element 1 is blown into the room from the air passage 8a by the damper 9 that switches the air passage in the air passage 8. When the dehumidifying performance of the moisture absorption element 1 is deteriorated, the damper 9 switches the air passage, and the humidified air heated by the heater 7 is connected through a duct or the like and discharged to the outside of the room although not shown.

In addition, by contacting the air heated by the heater with the moisture absorbing element in a moisture saturated state, the moisture retained in the moisture absorbing element can be desorbed and the moisture absorbing element can be regenerated, and it is provided on the wall surface.
