Abstract

A humidifier requiring no feed water, which is capable of sufficiently cooling a moistening rotor to effect sufficient humidification even in low-temperature low-humidity winter.

Utilizing the principle of the outdoor heat exchanger (22) of the air conditioner taking heat of evaporation from the outside air makes it possible to obtain cooled air; therefore, cooled air can be obtained without increasing cost and energy. The moistening rotor (12) cooled in the cooling region (C) has been cooled in the cooling region (C) with very low temperature air; therefore, even in winter when the outside air is at low temperature, the moistening rotor (12) is capable of collecting sufficient moisture from the outside air. The portion of the moistening rotor (12) which has sufficiently collected this moisture discharges the moisture to the high-temperature heated air in the moistening region.

Conventionally, as this type of non-water supply humidifier, there is one as shown in FIG. In this non-water supply humidifier, a disk-shaped humidifying port 2 made of an adsorbent such as silica gel zeolite is rotated by a motor (not shown) as shown by an arrow R, and each part of the humidifying rotor 2 is sequentially turned into a moisture absorbing area A. It passes through the humidification zone H and the heat collection zone T. The humidifying passage 3 passes through the humidifying region A, the humidifying passage 4 passes through the humidifying region H, and the heat collecting passage 5 passes through the heat collecting region T.

Then, the humidification rotor 2 absorbs moisture from the air passing through the moisture absorption passage 3 to the moisture absorption region A, and in the humidification region H, the moisture is added to the high-temperature air in the humidification passage 4 heated by the heater 6. For humidification. The air passing through the heat-collecting passage 5 recovers heat in the heat-collecting area T, cools each part of the humidifying rotor 2 before going to the moisture-absorbing area A, and the humidifying rotor 2 sufficiently absorbs moisture in the moisture-absorbing area A. Adsorption is possible, and the load on the heater 6 is reduced.

In this non-water supply humidifier, since the humidification rotor 2 absorbs moisture from the air in the moisture absorption passage 3 and releases moisture from the humidification rotor 2 to the air in the humidification passage 4, a water supply device is unnecessary. It has the advantage that.

By the way, in the conventional non-water supply humidifier described above, as shown in FIGS. 3 and 4, each part of the humidification rotor 2 is cooled in the heat collection area T and then enters the moisture absorption area A to adsorb moisture. However, since the humidifying rotor 2 has a considerably large heat capacity, the humidifying rotor 2 may not be sufficiently cooled, and may enter the moisture absorbing area A. When the temperature is low, there is a problem that the amount of moisture absorption is insufficient in the low temperature and low humidity winter, and the humidification may not be sufficient in the winter when the humidification is required most.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

As shown in FIG. 1, this non-water supply humidifier has a disk-shaped humidifier rotor 12. The humidifying rotor 12 is formed by molding an adsorbent such as silica gel, zeolite, or alumina into, for example, a honeycomb shape or a porous multi-particle shape. The humidifying rotor 12 is rotated around a central axis by a motor (not shown) in a direction of an arrow R, and each part is sequentially rotated by the rotation in a moisture absorbing area A, a humidifying area H, a heat collecting area T, and a cooling area. It passes through area C. Further, the humidifying rotor 12 is disposed in a casing (not shown), and the casing is partitioned by a partition plate (not shown). A heat collecting passage 5 passing through the heat collecting region T and a cooling passage 21 passing through the cooling region C are formed. The cooling passage 21 is located between the heat collection passage 5 and the moisture absorption passage 3 at a position passing through the humidification rotor 12. The humidification passage 4 is connected to the downstream side of the heat collection passage 5 and is an air preheated in the heat collection region T. It has a heater 6 as a heating means for further heating the air.

A humidifying fan 14 is provided downstream of the humidifying rotor 12 in the humidifying passage 4 to flow air as indicated by an arrow, and deprives the humidifying area H of moisture to bring humidified air into a room (not shown). I am trying to supply.

On the other hand, a moisture absorption fan 24 is provided downstream of the humidification rotor 12 of the moisture absorption passage 3 and downstream of the humidification rotor 12 of the cooling passage 21 so that, for example, the outside air at 0 ° C. As shown in the figure, it sucks and flows. The outside air is sucked into the moisture absorption passage 3, and when passing through the moisture absorption area A of the humidification rotor 12, moisture is adsorbed on the humidification rotor 12.

Further, on the upstream side of the humidifying rotor 12 of the cooling passage 21, a passage 23 through which cooling air of, for example, 13 to 15 ° C. cooled through an outdoor heat exchanger 22 as an evaporator is introduced. Are connected. Therefore, the humidification rotor 12 whose heat has been recovered and cooled in the heat collection area T is further cooled to an extremely low temperature in the cooling area C. Therefore, even if the outside air is at a low temperature of, for example, 0 ° C, the humidification rotor 12 is cooled to an extremely low temperature of, for example, _3 to 15 ° C. Also, the relative humidity of the air near the surface of the humidifying rotor 12 is high, so that moisture can be sufficiently adsorbed in the moisture absorption region A.

In the waterless humidifier with the above configuration, the outside air sucked into the heat collecting passage 5 by the humidifying fan 14 first recovers heat from the humidifying rotor 12 in the heat collecting region T and is preheated. Heated by heater 6 in passage 4. As described above, since the air is preheated in the heat collection region T and then heated by the heater 6, high-temperature heated air can be obtained with little energy. This heated air receives moisture evaporated from the humidification rotor 12 when passing through the humidification region H, becomes humidification air, and is supplied to a room (not shown) through the humidification fan 14.

On the other hand, since the humidifying rotor 12 rotates in the direction of arrow R, the humidifying rotor 12 corresponding to the heat collecting area T reaches the cooling area C. Cooling air cooled to 13 to 15 ° C flows into the cooling passage 21 passing through the cooling area C through the outdoor heat exchanger (evaporator) 22 of the air conditioner from the passage 23. And the humidification rotor 1 2 And then cooled down to low temperature. As described above, since the cooling air is obtained by utilizing the outdoor heat exchange 22 of the air conditioner taking away the evaporative heat from the outside air, the cooling air can be obtained without increasing the cost and the energy. The cooling air that has cooled the humidifying rotor 12 in the cooling area C is sucked by the moisture absorbing fan 24 and discharged to the outside. Next, the portion of the humidifying rotor 12 cooled in the cooling area C reaches the moisture absorbing area A. The low-temperature outside air of about 0 ° C flows into the moisture absorption area A from the moisture absorption passage 3, but the humidification rotor 12 is in the cooling area C, and is 13 to 15 from the outdoor heat exchanger 22. Even in winter, when the outside air is at low temperature and low humidity, the humidifying rotor 12 can sufficiently remove moisture from the outside air when the relative humidity of the outside air near the surface increases, even in winter when the outside air is at low temperature and low humidity. Can be collected. In particular, in the region A1 of the moisture absorption region A, which is close to the cooling region C, the humidification rotor 12 is at a very low temperature of 13 to 15 ° C. Can be collected.

The portion of the humidifying rotor 12 that has sufficiently collected this moisture then reaches the humidification region H, where the humidification region sufficiently releases moisture to the high-temperature heated air. The humidified air thus obtained is supplied to the room through the humidification fan 14.

In the above embodiment, the humidification rotor 12 is cooled to a very low temperature by utilizing the fact that the outside air is deprived of the heat of evaporation by the outdoor heat exchanger 22 of the air conditioner. Therefore, the humidification rotor 12 can sufficiently absorb moisture from the air passing through the moisture absorption passage A, and can sufficiently carry out the moisture of the air in the humidification passage H without increasing the cost and the energy.

In the above embodiment, the heat collecting region T and the heat collecting passage 5 are provided, but these may be omitted.

Also, the ratio of the areas of the above-mentioned moisture absorption region A, humidification region H, heat collection region T, and rejection region C is not limited to the ratios shown in FIGS. 1 and 2, and may be set to various ratios depending on the situation. Good. In the above embodiment, a power condenser using a heater may be used as the heating means.

As is clear from the above, according to the present invention, before the portion of the caro-humidity rotor faces the moisture absorption passage, the cooling passage through which the cooling air for cooling that portion is provided, The humid rotor can be cooled sufficiently before facing the humidifying passage, and therefore, even in low-temperature and low-humidity winters, the relative humidity of the air near the surface of the humidifying rotor can be increased, and the humidifying rotor can sufficiently absorb moisture from the outside air. Thus, the air in the humidifying passage can be sufficiently humidified. According to the non-water humidifier of one embodiment, after the humidification rotor is cooled by the air flowing through the heat collection passage and then cooled by the cooling air flowing through the cooling passage, the humidification port can be effectively cooled, Further, since heat is recovered from the humidifying rotor to the air in the heat collecting passage before cooling the humidifying rotor with the cooling air in the cooling passage, heat can be effectively recovered. According to the non-water supply humidifier of one embodiment, the air cooled by the evaporator passes through the passage and the cooling passage, reaches the humidifying rotor, and cools the humidifying rotor. Humidification rotor can be cooled by obtaining cooling air without increasing the amount of water, so that moisture can be sufficiently absorbed by the humidification rotor from the air passing through the moisture absorption passage without increasing cost and energy. Thus, the air in the humidifying passage can be sufficiently humidified.

According to the non-water humidifier of one embodiment, since the cooling region exists between the humidifying region and the humidifying region, each part of the humidifying rotor heated in the humidifying region is cooled before the humidifying region. Therefore, the air can be sufficiently cooled by the cooling air, so that the moisture can be sufficiently absorbed by the humidifying rotor from the air in the moisture absorbing region, and the air can be sufficiently humidified in the humidifying region.

According to the non-water supply humidifying device of one embodiment, the humidifying rotor whose heat has been recovered and cooled in the heat collecting region is further cooled by the cooling air flowing through the 7 retreat region, so that the humidifying rotor is effectively cooled. Since heat can be recovered from each part of the humidifying rotor to the heat collecting area before being cooled in the cooling area, the heat can be effectively recovered. Therefore, the humidification rotor can sufficiently absorb moisture from the air passing through the moisture absorption region, and can sufficiently humidify the air in the humidification region. According to the non-water humidifier of one embodiment, the air cooled by the evaporator is guided to the cooling area through the passage and the seven-way passage to cool the humidification rotor, thereby increasing the cost and energy. Without cooling air, the humidifying rotor can be cooled. Therefore, the humidifying rotor increases cost and energy. In addition, moisture can be sufficiently absorbed from the air in the moisture absorption region, and the air in the humidification passage can be sufficiently humidified.
