[0006]

According to the above-described ventilation system including the conventional water supply type humidification unit, even if moisture is supplied to the air by the water supply type humidification unit 118,
Since ventilation is always provided, the discharge of water is always accompanied by it. That is, the moisture supplied to the living room 115 flows out of the living room together with the air in the living room from the living room exhaust port 124 or the first bathroom air supply port 125, and does not contribute to an increase in the amount of water in the living room to the extent that the water flows out. . For this reason, the humidification capacity of the water supply type humidification unit 118 needs to always be set to be larger than the amount of water flowing out of the living room, and there is a problem that heat energy loss of the heater or loss of supplied water is caused. Was.

Further, the water supply type humidification unit 118 needs to be provided with water supply pipes in all rooms of the hotel, for example, so that it takes time and effort for construction or water leakage from the water supply pipes. There were various problems involved.

An object of the present invention is to provide a humidifying ventilation system having a humidifying device which is excellent in workability, has no risk of water leakage, and can supply moisture to a living room without lowering humidifying efficiency. Aim.

[0009]

A humidifying and ventilating system according to the present invention comprises an air supply means for supplying external air into a room, an exhaust means for exhausting indoor air to the outside, and an air exhausted by the exhaust means. Moisture transfer means is provided for collecting moisture therein and returning it to the room via a moisture supply path (claim 1).

In the above humidifier, since the moisture source is moisture adsorbed from the air passing through the moisture absorption passage, there is no need to provide a water supply pipe or the like. For this reason, since it is not necessary to arrange a water supply pipe over the whole building of a hotel, it is excellent in workability and there is no fear of water leakage. Humidification by the moisture transfer device can be made to have a sufficiently comfortable humidity environment in the room if moisture in the outside air is absorbed and accumulated while constantly taking in and exhausting outside air. The moisture supply path may be anything, such as a path that opens from the living room to the ceiling.

In the humidification and ventilation system of the present invention, for example, the room is constituted by the first room and the second room, and the moisture transfer means is connected to the exhaust means for exhausting the air from the second room. The humidifying passage is provided with a passage and a humidifying passage communicating with the moisture supply passage. The humidifying passage absorbs moisture, and the humidifying passage can provide moisture to the air sent into the first chamber.

According to the structure of the moisture transfer means, the transfer of the moisture can be performed with a compact structure.
It can be easily installed in an empty space such as an existing building. For this reason, it is possible to reduce construction costs and the like. In addition, as the above-mentioned wet separation and removal means, there are a heating means such as a heater, a decompression means and the like.

In the above humidification and ventilation system of the present invention, for example, the first chamber is constituted by two or more rooms, and the moisture transfer device adsorbs moisture in the moisture absorption passage communicating with the exhaust passage from the second chamber. Moisture can be given to the air sent into two or more rooms in the humidifying passage (claim 3).

With this configuration, it is possible to humidify a plurality of rooms by a simple system.

In the humidification and ventilation system of the present invention, for example, the humidification and ventilation system is arranged behind the ceiling, and the humidification passage is an air supply passage through which air exhausted from the first chamber is supplied to at least the first chamber. An opening is provided in a certain ceiling, and the air in the ceiling can be received and supplied to the first room (claim 4).

By disposing the humidification ventilation system above the ceiling, the first room and the second room can be widely used. In addition, for example, when an existing ventilation system is arranged above the ceiling and a humidifier is added thereto, the humidifier can be easily attached to the existing ventilation system above the ceiling. In addition, since the first chamber is usually supplied with air from the outside in addition to the air blown out from the humidifying passage, the supplied air becomes air behind the ceiling via the first chamber. In the humidifying passage, the air behind the ceiling is received and humidified and sent to the first chamber. Therefore, in the first room, the humidity of the air supplied from the outside is accumulated to a predetermined level, so that a comfortable humidity environment can be obtained. In addition, since the humidifying passage is opened behind the ceiling, it is not necessary to connect the humidifying passage with a pipe or the like, so that the construction cost can be reduced.

In the humidification and ventilation system of the present invention, it is desirable to provide, for example, a flow promoting means for promoting the flow of air in one of the air passages. By providing, for example, a fan or the like as the circulation promoting means, ventilation and humidification can be promoted.

In the humidification and ventilation system of the present invention, for example, the first room may be a living room and the second room may be a bathroom.

With this configuration, it is possible to absorb moisture in the air exhausted from the bathroom and humidify the air sent into the living room. For this reason, sufficient humidity can be given to the living room.

The air introduced from the hygroscopic air suction port 1 is adsorbed by the hygroscopic material disposed on the rotary type hygroscopic rotor 6 and exhausted from the hygroscopic air outlet 2 in a dry state. In the humidifying passage 11, the air sucked from the humidifying air inlet 3 is separated from the humidifying material by the moisture adsorbed in the humidifying passage 10 and is mixed with the humidified air. It is blown out from 4. While rotating and passing through the humidifying passage, the moisture absorbing material in the rotary moisture absorbing rotor is regenerated so that moisture is removed and moisture can be adsorbed again. In the rotary moisture absorbing rotor 6, the portion of the moisture absorbing material holding the moisture absorbed from the air in the moisture absorbing passage 10 is sequentially rotated and moved to a position where it is exposed to the air passing through the humidifying passage 11.
