Abstract

PROBLEM TO BE SOLVED: To obtain a humidity-control equipment, in which heating efficiency is not decreased, even if an operation for quick increase of humidity is conducted at the early stage of the humidifying operation. SOLUTION: The humidity-control equipment is equipped with a hygroscopic rotor 10, a hygroscopic ventilation duct 20, a regenerative ventilation duct 30, and dumpers 40, 60. In the duct 20, air is passed through a specified part of the rotor 10 to allow the part to absorb moisture in the air. In the duct 30, heated air is passed through another specified part of the rotor 10 to transpire the moisture held in the rotor into the heated air. The dumpers 40, 60 form an air flow by introducing outside air into the ventilation duct 20 and returning it to the outside, and also an air flow by introducing indoor air to the ventilation duct 30 and returning it into the room. The dumpers 40, 60 can also form air flows by introducing outdoor air and indoor air simultaneously into the ventilation duct 20 and discharging the air to the outside after passing it through the rotor 10.

The moisture absorbing rotor absorbs a large amount of water. However, since the air moisturized by the moisture absorption rotor is discharged as it is to the outside of the room, a large amount of warm indoor air flows out when the room is heated. Moreover, since a large amount of cold air flows in from the outside instead of being replaced, the heating efficiency is significantly reduced.

Move to heated air. Since the heated air is discharged from the outlet 46 as it is, the moisture outside the room is transferred into the room. The moisture absorption rotor 10 that has been regenerated to a dry state advances to a position where it crosses the moisture absorption ventilation passage 20, and there again absorbs the moisture in the outdoor air. By continuously performing such an operation, moisture is supplied to the room air, and the humidity of the room air rises.

The position of the rotary damper 48 is the same as in FIG. However, this time, the position of the damper plate 61 has changed. That is, the damper plate 61 blocks the ventilation path from the suction port 51 to the moisture absorption blower 22, and opens the ventilation path from the suction port 21 to the moisture absorption blower 22. This time, suction port 21
The indoor air is further introduced into the moisture absorption ventilation passage 20, the moisture is absorbed by the moisture absorption rotor 10 and becomes dry air, and then the air outlet 4

On the other hand, the indoor air introduced from the suction port 31 into the regenerating air passage 30 and heated by the regenerating heater 33 returns to the room from the air outlet 46 after recovering moisture from the moisture absorption rotor 10. The outdoor air flows into the room in an amount commensurate with the air discharged from the air outlet 47, and the moisture contained therein is supplied to the indoor air, so that the humidity of the indoor air rises.

The position of the rotary damper 48 is the same as in FIG. This time, the damper plate 61 moves from the suction port 51 to the moisture absorption blower 2
Both the ventilation passage leading to No. 2 and the ventilation passage leading from the suction port 21 to the moisture absorption blower 22 are both in the open position. Therefore, suction port 5
The outdoor air is introduced from 1 and the indoor air is introduced from the suction port 21 at the same time. The outdoor air and the indoor air join together and proceed along the moisture absorption ventilation path 20, the moisture is absorbed by the moisture absorption rotor 10 to become dry air, and then the air is discharged from the air outlet 47 to the outside.
In the regeneration ventilation passage 30, the indoor air is introduced from the suction port 31 and heated by the regeneration heater 33, and then the moisture absorption rotor 1
0, the moisture is collected from the moisture absorption rotor 10 and then returned to the room through the air outlet 46. The outdoor air flows into the room by an amount commensurate with the amount of the indoor air discharged from the air outlet 47, and the water contained therein is supplied to the indoor air.
The humidity of the indoor air rises.

The rotation speed of 2 is increased to increase the amount of air flowing through the moisture absorption ventilation passage 20 so that a large amount of water is absorbed by the moisture absorption rotor 10 in a short time. Let the air volume at this time be Q2. When the moisture absorption rotor 10 contains a large amount of water, the amount of water evaporated into the heated air in the regenerated air passage 30 also increases, so that the humidity of the indoor air rises in a short time.

には全く影響がない。As described above, the moisture for humidifying the indoor air is obtained from the outdoor air, and the air after removing the moisture is returned to the outside again. Therefore, even if the room is heated, the amount of heat can be reduced. Don't run outside. Even if a large amount of outdoor air is flown to obtain a large amount of water in a short time, the heating efficiency is not affected at all.

The “predetermined condition” is “when the humidity of the indoor air reaches a set value” or “when the humidity of the indoor air rises by a set value”. Since a humidity sensor that measures the humidity of the indoor air is required for this condition determination, when the humidity sensor cannot be prepared, it may be "when a predetermined time has elapsed after the start of the humidifying operation". In the "indoor air only mode", the rotation speed of the moisture absorption blower 22 is reduced to reduce the amount of air flowing through the moisture absorption ventilation passage 20. The air volume at this time is Q1.

Similar to the case of the "outdoor air only mode", the rotation speed of the moisture absorption blower 22 is increased to increase the amount of air flowing through the moisture absorption ventilation passage 20 so that a large amount of moisture is absorbed by the moisture absorption rotor 10. Further, when the predetermined condition is reached, the "indoor air only mode" of FIG. 2 is switched to, and the air volume is also reduced.

【００３６】所定条件に達した後、言い換えれば安定状

する。When the humidifying operation is started, the humidity of the indoor air rises and becomes stable when a certain humidity level is reached. Figure 4
Shown in Fig. 7 is the water balance when the humidifying operation is performed by the conventional humidity controller. The volume of the room is 100 m 3 , the natural ventilation rate is 1.0 times / h, and the outdoor air has a temperature of 5 ° C. and a humidity of 50%. The amount of air flowing through the moisture absorption ventilation passage of the humidity controller is set to 100 m 3 / h, which is the same as the amount of air replaced by natural ventilation. In addition, the regeneration capacity of the humidity controller has a chamber volume of 100 m 3 ,
It is assumed that the natural ventilation rate is 1.0 times / h, the outdoor air is used at a temperature of 5 ° C. and a humidity of 50%, and the amount of water regenerated by the regenerative heater is 340 g / h.

湿度は一定レベルで安定する。Due to natural ventilation, 100 m 3 / h of outdoor air flows into the room, and an equal amount of air is exhausted to the outside from the humidity controller. About 100 g of water is contained in 100 m 3 of air having a temperature of 5 ° C. and a humidity of 50%, and all of the water is recovered when passing through the moisture absorption rotor of the humidity controller. Therefore, 340 g / h of water is continuously supplied to the room, and the humidity of the room air is stabilized at a constant level.

出される。When the amount of air flowing through the moisture absorption ventilation passage is smaller than the amount of natural ventilation, the following occurs. In the example shown in FIG. 5, the air volume flowing through the moisture absorption ventilation passage is 50 m 3 / h and the natural ventilation volume is 100 m 3
It is half of / h. Therefore, 100m 3 / h of outdoor air flows into the room by natural ventilation, and 50m 3
/ H is exhausted to the outside from the humidity controller. At this time, the temperature is 5 ℃
In about 170g included in the humidity of 50% air 50 m 3

The remaining 50 m 3 / h of the outdoor air of / h, which is not exhausted by the humidity controller, flows out to the outside due to the pressure difference between the inside and the outside in a state of containing about 170 g or more of water. Therefore, 170 g / h of water is constantly supplied to the room, and the indoor humidity is stabilized at a constant level. However, less water is supplied to the room than when the amount of air flowing through the moisture absorption ventilation passage is 100 m 3 / h.

【００４１】吸湿通風路を流れる風量が自然換気量より

In the example shown in FIG. 6, the amount of air flowing through the moisture absorption ventilation passage is 150 m 3 / h, and the natural ventilation is 100 m 3
It is a 50% increase of / h. Here, the outdoor air of 100 m 3 / h flowing into the room by natural ventilation and 50 m 3 / h of the air remaining in the room are exhausted to the outside by the humidity controller. This 150 m 3 / h of air contains at least 510 g of water.

Since the amount of water regenerated by 340 g / h is 340 g / h, 340 g of 510 g of water is collected and discharged indoors, but the remaining 170 g is discharged outside the room without being captured by the moisture absorption rotor. Therefore, although 340 g / h of water is continuously supplied to the room, 170
Since g / h of water is continuously discharged to the outside of the room, the indoor humidity stabilizes at a certain level, but the amount of water supplied to the inside of the room is reduced compared to when the amount of air flowing through the moisture absorption ventilation path is 100 m 3 / h. Will end up.

ことが室内空気の加湿効率向上につながるものである。Therefore, it is desirable that the airtight state of the chamber and the amount of air exhausted to the outside by the humidity controller maintain an appropriate balance. That is, it is possible to improve the humidification efficiency of the indoor air by collecting moisture in the moisture absorption rotor and discharging the same amount of air as the natural ventilation of the room to the outside in a dry state.

That is, the air flow rate Q2, which is larger than the air flow rate Q1 in the stable state, flows through the moisture absorption passage 20, but in Q2, the air flow rate Q3 introduced from the suction port 21 facing the room 100.
Is set to be equal to the amount of air flowing out of the room by natural ventilation. The natural ventilation amount itself is set in consideration of general usage conditions (room volume, indoor and outdoor temperature and humidity, etc.) of the humidity controller 1. This makes it possible to raise the humidity of the indoor air in a short time while maintaining the heating effect of the room,
An efficient humidification operation can be performed.

If the motor 11, the moisture absorption blower 22, the regeneration blower 32, and the regeneration heater 33 are energized while communicating with the outer outlet 47, the dehumidification operation is performed as in the case of FIG. 8.

とができる。According to the present invention, the moisture absorption rotor, the moisture absorption air passage for allowing the moisture absorption rotor to absorb the moisture in the air by passing the air through the specific portion of the moisture absorption rotor, and the heating air for the other specific portion of the moisture absorption rotor. A recirculation air passage through which moisture contained in the moisture absorption rotor is evaporated into the heating air, and an air flow that introduces outdoor air into the moisture absorption ventilation passage and returns it to the outside again, and a room in the regeneration ventilation passage. Since it was decided to equip the humidity controller with a damper device that introduces air and forms a flow of air that returns it to the room again, moisture for humidification will be taken from the outdoor air, and at the beginning of the humidification operation. Since a large amount of water is rapidly taken in, even if a large amount of outdoor air is made to flow, it does not lead to the outflow of heat to the outside, and the heating efficiency is not reduced. According to the present invention, the moisture absorption rotor, the moisture absorption air passage that allows air to pass through the specific portion of the moisture absorption rotor and allows the moisture absorption rotor to absorb the moisture in the air, and the heated air that passes through the other specific portion of the moisture absorption rotor. The regenerated air passage to evaporate the water contained in the heated air, the outdoor air is introduced to the moisture absorption air passage, the flow of air to return it to the outside again, and the indoor air is introduced to the regenerated air passage. , A damper device capable of forming a flow of air that returns this indoors and a flow of air that introduces the room air into the moisture absorption ventilation passage and discharges it outside the room after passing through the moisture absorption rotor. With the provision of the humidifier, after starting the humidifying operation, it is decided to introduce the outdoor air into the moisture absorption ventilation passage until the predetermined condition is reached, and to introduce the indoor air after the predetermined condition is achieved,
By introducing outdoor air into the moisture absorption passage and returning it to the outside again, it is possible to take in moisture for humidification from the outdoor air, and to take in a large amount of outdoor air in the early stage of the humidifying operation so that a large amount of outdoor air is taken in.
