Abstract

The present invention addresses the problem of providing a humidification unit capable of increasing a humidification amount even when a regeneration air volume is limited. Since the temperature of air heated at a first heating device (41) drops after the air passes through a first moisture release area (51b), the air has insufficient thermal energy even when the air directly enters a second moisture release area (52b). Thus, the air that has passed through the first moisture release area (51b) is heated and is imparted with thermal energy at a second heating device (42) and then enters the second moisture release area (52b). Accordingly, the humidification amount can be increased even when the regeneration air volume is limited.

Description

In recent years, humidification units using suction members have become widespread. For example, in a humidity control apparatus disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 2007-327712), a desiccant rotor in which air flowing in an adsorption zone and air flowing in a regeneration zone form substantially opposite flows, a heat exchanger, Is used to recover the heat of condensation of the desiccant and the heat of the indoor return air.

On the other hand, when it is desired to increase the humidification amount while the regeneration air volume is fixed, if there is only one rotor, a heater is employed as a heating device and the heater input is increased. In such a case, the temperature of the air passing through the heater becomes locally high, which is not preferable in terms of product safety.

Therefore, there is a problem to provide a humidifying unit capable of increasing the humidifying amount even when the amount of the regenerated air is restricted.

Therefore, the air that has passed through the first moisture release region enters the second moisture release region after being heated by the second heating device and given thermal energy. As a result, the humidification amount can be increased even when the amount of regeneration air is restricted.

The humidification unit according to the second aspect is the humidification unit according to the first aspect, further including a common blower that generates air passing through the first moisture release area and the second moisture release area.

The humidification unit according to the third aspect is the humidification unit according to the first aspect or the second aspect.

In the second adsorbing member, the second moisture releasing area and the second moisture adsorbing area are switched by rotation. The second suction member further has a second purge area. The cooling air is supplied to the second purge region as a region for cooling a portion that was the second moisture release region before the second moisture release region was switched to the second moisture adsorption region.

Point C corresponds to the air that has passed through first heating device 41. Point D corresponds to the air that has passed through first moisture release area 51b. Point E corresponds to the air that has passed through second heating device 42. Point F corresponds to the air that has passed through second moisture release area 52b.

(4) The outside air taken into the purge passage Pc passes through the second purge region 52c, so that a small amount of water is adsorbed by the second humidification rotor 52, and the second humidification rotor 52 is cooled. Therefore, the temperature of the air at point B 'is slightly higher and the absolute humidity is slightly lower than that of the outside air.

(4) The outside air that has passed through the second purge area 52c passes through the first purge area 51c, so that a small amount of water is adsorbed by the first humidification rotor 51, and the first humidification rotor 51 is cooled. Therefore, as compared with the outside air, the air at the point B has a slightly higher temperature and a slightly lower absolute humidity.

Next, the air at the point C that has passed through the first heating device 41 is in a state in which only the temperature has risen to Tc without changing the absolute humidity as compared with the air at the point B.

Then, the air at the point D that has passed through the first moisture releasing area 51b is cooled by the humidifying rotor 51 at the same time as the moisture is supplied from the humidifying rotor 51 by passing through the first moisture releasing area 51b, and the air at the point C is cooled. In this state, the absolute humidity increases and the temperature decreases to Td.

Next, the air at the point E that has passed through the second heating device 42 is in a state where only the temperature has risen to Te without changing the absolute humidity as compared with the air at the point D.

Then, the air at the point F that has passed through the second moisture release area 52b is cooled by the humidification rotor 52 at the same time as the water is applied from the second humidification rotor 52 by passing through the second moisture release area 52b, and the point E is cooled. This is a state in which the absolute humidity is higher and the temperature is lower than the air.

As described above, the air that has passed through the first moisture release area 51b is humidified at the stage of transition from the state of the air at the point C to the state of air at the point D, and the air that has passed through the second moisture release area 52b is The humidification is performed at the stage where the state of the air at the point E changes to the state of the air at the point F, and the humidification is performed twice in total.

Therefore, the humidification unit 100 according to the first embodiment, the first modification, and the fourth modification can supply sufficient moisture even when the amount of regeneration air cannot be increased because the amount of regeneration air is limited.

(6) Dehydration Operation of Moisture in Second Modification and Third Modification The desorption operation of moisture in the humidifying unit 100 according to the second modification and the third modification will be described with reference to the psychrometric chart of FIG. 9B. .

Point B corresponds to the air that has passed through the second purge area 52c and the air that has passed through the first purge area 51c.

The description after the point C is the same as the desorption operation of moisture in the humidifying unit 100 according to the first embodiment, the first modification, and the fourth modification.

Therefore, the humidifying units 100 according to the second and third modified examples can provide sufficient moisture even when the amount of regenerated air cannot be increased because the amount of regenerated air is limited.

<Second embodiment>
(1) Overall Configuration FIG. 6A is a perspective view of a main part of a humidifying unit 300 according to the second embodiment of the present disclosure. FIG. 6B is a main part configuration diagram of the humidification unit 300 in which the air passage of FIG. 6A is simplified and described. 6A and 6B, the humidification unit 300 includes an air passage P, a first humidification rotor 151, a second humidification rotor 152, a first heating device 141, and a second heating device as in the first embodiment. 142.

Further, similarly to the first embodiment, the outside air supply passage Pa is provided between the first outside air supply passage Pa1 through which the air for passing through the first moisture adsorption region 151a of the first humidification rotor 151 and the second humidification rotor 152. It includes a second outside air supply passage Pa2 through which air for passing through the second moisture adsorption region 152a flows.

In addition, the regeneration passage Pb is configured to supply the regeneration air heated by the first heating device 141 to the first moisture release region 151b of the first humidification rotor 151, the first regeneration passage Pb1, and the regeneration air heated by the second heating device 142. The second humidification rotor 152 includes a second regeneration passage Pb2 that flows to the second moisture release region 152b of the second humidification rotor 152.

(2) Difference from First Embodiment In the first embodiment, the first humidification rotor 51 is provided with the first purge area 51c, and the second humidification rotor 52 is provided with the second purge area 52c. In the second embodiment, the first humidification rotor 151 and the second humidification rotor 152 are not provided with a purge area. Therefore, the air passage P does not include the purge passage Pc.

(3) Detailed description As described above, the humidification unit 300 of the second embodiment has a configuration in which the air passage is different from the air passage of the first embodiment because each humidification rotor has no purge area.

Therefore, here, only the humidification rotor and the air passage P will be described, and the same or similar members or components as those used in the first embodiment are denoted by the same names and the same reference numerals. Therefore, detailed description of the configuration and operation will be omitted.

(3-1) First humidification rotor 151 and second humidification rotor 152
The first humidification rotor 151 is configured by supporting an adsorbent on the surface of a disk-shaped porous base material, and as shown in FIG. 6A, is provided with a first outside air supply passage Pa1 and a first regeneration passage Pb1. It is arranged straddling. Similarly, the second humidification rotor 152 is configured by supporting an adsorbent on the surface of a disk-shaped porous base material, and as shown in FIG. 6A, a second outside air supply passage Pa2 and a second regeneration passage It is arranged over Pb2.

{Circle around (1)} The first humidification rotor 151 has a first moisture adsorption region 151a arranged in the first outside air supply passage Pa1, and a first moisture discharge region 151b arranged in the first regeneration passage Pb1. Then, the adsorbent carried by the first humidification rotor 151 alternately moves between the first moisture adsorption area 151a and the first moisture release area 151b as the first humidification rotor 151 rotates.

Similarly, the second humidification rotor 152 has a second moisture adsorption region 152a arranged in the second outside air supply passage Pa2, and a second moisture discharge region 152b arranged in the second regeneration passage Pb2. Then, the adsorbent carried by the second humidifying rotor 152 moves alternately between the second moisture adsorbing region 152a and the second moisture releasing region 152b as the second humidifying rotor 152 rotates.

(3-2) First heating device 141 and second heating device 142
Although the first heating device 141 and the second heating device 142 may be heaters, here, a condenser of a refrigerating device is employed. This is because the first humidification rotor 151 and the second humidification rotor 152 are not provided with a purge area, so that the first moisture release area 151b and the second moisture release area 152b are heated to a high temperature using a condenser whose temperature is lower than that of the heater. This is in order to prevent from becoming too much. Note that a heater whose temperature can be controlled may be used instead of the condenser.

In the first moisture releasing area 151b and the second moisture releasing area 152b of the first humidifying rotor 151 and the second humidifying rotor 152, air heated by the first heating device 141 and the second heating device 142 to reduce the relative humidity is reduced. Since the water passes through, the moisture adsorbed by the first moisture adsorbing region 151a and the second moisture adsorbing region 152a is released to the passing air in the first moisture releasing region 151b and the second moisture releasing region 152b, and the conditioned air And supplied indoors.

(3-3) First outside air supply passage Pa1 and second outside air supply passage Pa2
The outside air introduced from the outdoor space flows through the first outside air supply passage Pa1 and the second outside air supply passage Pa2. In the present embodiment, as shown in FIGS. 6A and 6B, the outside air that has passed through the second moisture adsorption region 152a from the inlet opening I through the second outside air supply passage Pa2 passes through the first outside air supply passage Pa1 as it is, The water is discharged from the outlet opening O to the outside through the moisture adsorption area 151a.

(3-4) First regeneration passage Pb1 and second regeneration passage Pb2
Air for regenerating the adsorbent, that is, air for releasing moisture adsorbed by the adsorbent of the humidifying rotor, flows through the first regeneration passage Pb1 and the second regeneration passage Pb2. In the present embodiment, as shown in FIGS. 6A and 6B, the outside air that has passed through the first moisture release region 151b via the first regeneration passage Pb1 passes through the second moisture release region 152b via the second regeneration passage Pb2 as it is. After that, it is supplied to the room.

(4) Features of the second embodiment (4-1)
Since the temperature of the air heated by the first heating device 141 decreases after passing through the first moisture release region 151b, the heat energy is insufficient even if the air enters the second moisture release region 152b as it is. Therefore, the air that has passed through the first moisture release region 151b enters the second moisture release region 152b after being heated by the second heating device 42 and given thermal energy. As a result, the humidification amount can be increased even when the amount of regeneration air is restricted.

(4-2)
Therefore, even with one humidifying fan 54, the humidifying amount can be increased.

(5) Modification FIG. 7A is a perspective view of a main part of a humidification unit 300 according to a modification of the second embodiment. FIG. 7B is a main part configuration diagram of a humidification unit 300 according to a modification of the second embodiment in which the air passage of FIG. 7A is simplified. In FIGS. 7A and 7B, a partition plate PLa that divides the outside air supply passage Pa into left and right is provided substantially at the center of the space between the first moisture adsorption region 151a and the second moisture adsorption region 152a in the outside air supply passage Pa. Is provided.

外 An outside air inlet Ia for introducing outside air is provided on a wall of a space sandwiched between the partition plate PLa and the first moisture adsorption region 151a. In addition, a discharge port Oa for discharging air that has passed through the second moisture adsorption area 152a is provided on a wall of a space sandwiched between the partition plate PLc and the second moisture adsorption area 152a.

一端 One end of the first duct Da is connected to the discharge port Oa. The first duct Da joins the air discharged from the outlet Oa and the air that has passed through the first moisture adsorption region 151a. Therefore, a junction Je is provided on the downstream wall of the first moisture adsorption region 151a. The other end of the first duct Da is connected to the junction Je.

In the humidification unit 300 according to the modified example, the outside air that has passed through the second moisture adsorption region 152a from the inlet opening I via the second outside air supply passage Pa2 does not pass through the first moisture adsorption region 151a but passes through the first outlet through the first moisture adsorption region 151a. It is discharged to the duct Da. On the other hand, outside air directly introduced from the outdoor space through the outside air inlet Ia flows into the first outside air supply passage Pa1, and the outside air passes through the first moisture adsorption region 151a and is discharged outside through the outlet opening O. .

As described above, the passage of the air flowing through each of the first moisture adsorption region 151a and the second moisture adsorption region 152a, that is, the first outside air supply passage Pa1 and the second outside air supply passage Pa2 are provided in parallel, and the first moisture adsorption region 151a is provided. The air that has not passed through any of the first and second moisture adsorption regions 152a passes through the first and second

moisture adsorption regions

151a and 152a. Therefore, in comparison with the first embodiment, the air that has passed through the second moisture adsorption region 152a does not need to pass through the first moisture adsorption region 151a, and the amount of moisture adsorption in the first moisture adsorption region 151a decreases. That is avoided.

(6) Operation of Desorbing Water in Second Embodiment and Modified Example The operation of desorbing water in the humidifying unit 300 according to the second embodiment and the modified example will be described with reference to the psychrometric chart of FIG. 9C. In FIG. 9C, point Q corresponds to outside air before being taken into regeneration passage Pb. Point R corresponds to the air that has passed through first heating device 141. The point S corresponds to the air that has passed through the first moisture release area 151b. Point T corresponds to the air that has passed through second heating device 142. Point U corresponds to the air that has passed through second moisture release area 152b.

{Circle around (2)} The outside air taken into the regeneration passage Pb passes through the first heating device 141, and the air at the point R is in a state where the absolute humidity does not change and only the temperature rises to Tr compared to the air at the point Q.

Then, the air at the point S that has passed through the first moisture release area 151b is cooled by the humidification rotor 151 at the same time as the moisture is applied from the humidification rotor 151 by passing through the first moisture release area 151b, and the air at the point R In this state, the absolute humidity increases and the temperature decreases to Ts.

Next, the air at the point T that has passed through the second heating device 142 is in a state where only the temperature has risen to Tt without changing the absolute humidity as compared with the air at the point S.

Then, the air at the point U that has passed through the second moisture release area 152b is cooled by the humidification rotor 152 at the same time as the water is applied from the second humidification rotor 152 by passing through the second moisture release area 152b, and the point T This is a state in which the absolute humidity is higher and the temperature is lower than the air.

As described above, the air that has passed through the first moisture release area 151b is humidified at the stage of transition from the state of the air at the point R to the state of air at the point S, and the air that has passed through the second moisture release area 152b is Is humidified at the stage of transition from the state of air at the point T to the state of air at the point U, and is humidified twice in total.

Therefore, the humidification unit 300 according to the second embodiment and the modified example can provide sufficient moisture even when the amount of regenerated air cannot be increased because the amount of regenerated air is limited.
