Abstract

PURPOSE:To obtain efficient and moreover stable humidification by rotating the humidification module in a humidifier which has a humidification module comprising a hollow porous body. CONSTITUTION:A humidification module 10 which comprises a large number of hollow porous members 1 laid out around a supporting shaft 2 at a specified span is pivoted by way of a supporting shaft 2 where there are formed fine pores 31c which prevent the passage of water but allow the passage of aqueous steam in the hollow porous members 1 in a fluorine resin-made hollow system 31. Each hollow porous member 1 is designed so that water may be supplied thereinto. The rotation of the humidification module 10 around the supporting shaft 2 promotes a scavenging action of each hollow porous member in its periphery and provides constantly stabilized differential vapor pressure, thereby embodying an advanced humidification effect.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier and an air conditioner equipped with a humidifier.

0002

[Prior Art] In recent years, humidifiers have been increasingly used as a means to prevent excessive drying during room heating or low-temperature storage of fruits and vegetables. Various methods are known, such as an electric heating method that humidifies water by evaporating it, and a spray method that humidifies water by evaporating water sprayed from a sprayer. It may be expensive, or the humidification efficiency may be poor.
In addition, problems have been pointed out in advance, such as impurities in water being directly included in humidified steam and contributing to air pollution.

[0003] Due to these circumstances, for example, Japanese Patent Application Laid-Open No. 2-1
As disclosed in Japanese Patent No. 3741, a large number of fine holes are formed on the outer circumferential surface of a heat-resistant tube with a size that does not allow water to pass through but allows water vapor to pass through, and the water inside the tube is evaporated by the difference in steam pressure. A method (so-called microporous method) has been proposed in which humidification is performed by releasing humidification to the outside through the large number of pores.

0004

[Problem to be Solved by the Invention] However, in conventional microporous type humidifiers such as the above-mentioned known example, only water vapor is released through the micropores, which prevents impurities in the water from being released into the air. However, since a large number of porous tubes each having a large number of micropores are bundled together and water is allowed to flow through each porous tube, the air permeability between the porous tubes is poor. ,
For example, even if this tube bundle is placed in the ventilation path of an air conditioner, there is a problem that the evaporation and release of water from each of the micropores and the diffusion effect to the surrounding air are low, and sufficient humidification efficiency cannot be obtained. there were.

[0005] Furthermore, this porous tube has a relatively large diameter because the heating fluid tube is arranged inside the porous tube in the form of a double tube. For this reason, the contact area between each porous tube and the air is small compared to the total volume of the humidifier (in other words, the volumetric efficiency is relatively poor), and due to flexibility constraints, this is used to create a humidifier. There are problems such as a low degree of freedom in selecting the shape in each case.

Therefore, in the present invention, in a humidifier configured to diffuse water vapor through a large number of fine holes, the air permeability around each hollow fiber porous body is improved by rotating a humidifying module made of hollow fiber porous bodies. This was done with the aim of improving the humidification efficiency by making the hollow fiber porous body as small as possible, and also to improve the volume efficiency and the degree of freedom in setting the shape by making the diameter of the hollow fiber porous body as small as possible.

[0007]

[Means for Solving the Problems] In the present invention, as a means for solving the problems, in the humidifier according to claim 1, as illustrated in FIG. 1A, FIG. 4, FIG. 6, and FIG. A large number of hollow fiber porous bodies 1 are arranged around a support shaft 2 at predetermined intervals, each having a large number of fine pores 31c formed in hollow fibers 31 made of fabric to prevent the passage of water but allow the passage of water vapor. The humidifying module 10 is rotatably supported via the spindle 2, and water can be supplied into each of the hollow fiber porous bodies 1, 1, . . . .

In a humidifier according to a second aspect of the present invention, as illustrated in FIGS.
1, . . . are formed in a sagging shape and are wound spirally around the support shaft 2.

[0009] In the humidifier according to claim 3, FIGS.
As illustrated in , in the humidifier according to claim 1, the humidifying module 10 is formed by a large number of hollow fiber porous bodies extending between a pair of straight support rods 11 and 12 arranged substantially parallel to each other. 1, 1, . . , arranged at predetermined intervals, a plurality of substantially flat hollow fiber units 9 are arranged radially around the support shaft (2).

In a humidifier according to a fourth aspect of the present invention, as illustrated in FIG. A plurality of substantially curved sag-shaped hollow fiber units 9, each having a large number of hollow fiber porous bodies 1, 1, etc. arranged at predetermined intervals, are arranged radially around the support shaft 2. It is characterized by being configured by arranging individual pieces.

In a humidifier according to a fifth aspect of the present invention, in the humidifier of the first aspect, the humidifying module 10 is formed by winding the hollow fiber porous bodies 1, 1, . . . in a spiral shape, as illustrated in FIG. The present invention is characterized in that a plurality of hollow fiber units 9, 9, .

In an air conditioner equipped with a humidifier according to a sixth aspect of the present invention, as illustrated in FIG. It is characterized in that the humidifiers Z1 to Z4 according to claims 1, 2, 3, 4, or 5 are arranged in a state where they are exposed to the humidifier 51.

[0013]

[Function] (a) The humidifier according to claim 1 provides the following effects. That is, the water supplied into each hollow fiber porous body 1, 1,... of the humidifying module 10 flows through each hole 31c, 31c,... due to the vapor pressure difference between the water and the outside air.
It evaporates due to a vapor pressure difference on the inner circumferential surface of the hollow fiber 31 that comes into contact with the outside air through the holes 31c, 31c.
・It is released to the outside, mixes with the outside air, and humidifies it. In this case, a large number of hollow fiber porous bodies 1, 1, . Since a high air blowing effect is obtained for each of the hollow fiber porous bodies 1, 1,..., the chances of contact between each of the hollow fiber porous bodies 1, 1,... and the surrounding air increase, and the vapor pressure difference is constantly maintained. It is maintained almost constant, and the generation of water vapor from each of the hollow fiber porous bodies 1, 1, . . . and its diffusion humidifying effect on the surrounding air are maintained stably and at a high level. Note that water in the hollow fiber porous body 1 does not leak to the outside of the hollow fiber porous body 1 because each hole 31c is set to a size that does not allow water to pass therethrough.

Furthermore, since water is directly absorbed into the interior of each hollow fiber porous body 1, the diameter of the hollow fiber porous body 1 must be set to the minimum diameter that can ensure water permeability. For example, when the volume of the humidifying module 10 in which the hollow fiber porous bodies 1, 1, etc. are arranged in a row is constant, the contact area between the humidifying module 10 and the air is expanded, and the volumetric efficiency is increased. It will be done.

[0015] Also, in this way, each hollow fiber porous body 1, 1,
... can be configured to have a smaller diameter, the humidifying module 10 formed by arranging a large number of the hollow fiber porous bodies 1 has good moldability, and the degree of freedom in setting the shape of the humidifier is increased. .

(b) In the humidifier according to claim 2, in addition to the effect described in (a) above, the humidifying module 10 has a large number of hollow fiber porous bodies 1, 1, etc. formed in a sag shape, and Since it is configured by winding it spirally around the support shaft 2, it is possible to improve the ventilation around the hollow fiber porous bodies 1, 1, etc. and the required contact area between the humidifying module 10 and the air. It is possible to obtain the effect of promoting compactness of the external shape of the humidifier while ensuring the same.

(c) In the humidifier according to claim 3, in addition to the effect described in (a) above, the humidifying module 10 includes a plurality of hollow fiber units 9, 9 arranged radially around the support shaft 2. ,..., compared to, for example, the case where the humidifying module 10 is formed into a single flat plate shape, the device can be made more compact, and each hollow fiber unit of the humidifying module 10 9, 9, . . . are exposed to the outside of the device, effects such as ease of maintenance can be obtained.

(d) In the humidifier according to claim 4, in addition to the effects described in (a) and (c) above, each hollow fiber unit 9, 9, . . . forming the humidifying module 10 is substantially curved. Since it is formed in a sagging shape and is rotated while being arranged radially around the support shaft 2, the humidifying module 10 acts as a kind of rotary blade, and each hollow fiber porous body 1, 1, . . . This will further enhance the air blowing effect.

(e) In the humidifier according to claim 5, in addition to the effect described in (a) above, the hollow fiber unit 9 formed by winding the hollow fiber porous body 1 in a spiral shape is attached to the support shaft 2. Since the support shaft 2 is arranged in multiple stages at predetermined intervals in the axial direction of the support shaft 2, a high contact effect with air can be obtained especially when ventilation is carried out in the axial direction of the support shaft 2. .

(f) In the air conditioner equipped with a humidifier according to claim 6, the humidifiers Z1 to Z4 having the humidifying module 10 rotatable around the spindle 2 are arranged to be exposed in the ventilation path 51. Therefore, the water vapor generated from the humidifiers Z1 to Z4 is transferred to the ventilation path 5 while suppressing an increase in the flow resistance of the conditioned air flowing through the ventilation path 51 as much as possible.
It is possible to accurately and efficiently mix the air conditioned air flowing through the interior of the air conditioner 1 and humidify the air. Also, in this case,
Since the humidifier is rotatable, each hollow fiber porous body 1 of the humidifier can be rotated by the dynamic pressure of the conditioned air flowing through the ventilation passage 51 or by a dedicated driving means. , 1, ... by increasing the chance of contact with the air as much as possible to obtain a higher humidifying effect, and by controlling the rotation appropriately, the humidification corresponds to the surrounding air conditions. This allows for easy adjustment.

[0021]

[Effects of the Invention] Therefore, according to each invention of the present application, the following effects can be obtained.

[0022] According to the humidifier according to claim 1, each of the hollow fiber porous bodies 1, 1, . . .
Since the hollow fiber porous bodies 1, 1, etc. are spaced apart from each other at a predetermined distance and are rotatable around the spindle 2, the chances of contact between each of the hollow fiber porous bodies 1, 1, etc. and the surrounding air are increased. Since the water vapor pressure around the porous bodies 1, 1,... is maintained almost constant at all times, for example, each hollow fiber porous body 1, 1,...
・Compared to humidifiers with a conventional structure in which the humidifiers are placed relatively close to each other and the ventilation between them is relatively poor, the humidifiers are fixedly placed, the effect is that higher humidification efficiency can be ensured. That's what you get.

Furthermore, since each of the hollow fiber porous bodies 1, 1, . .

Furthermore, since water vapor is obtained from the difference in vapor pressure between the water inside the hollow fiber porous body 1 and the air outside it, there is no possibility of humidification exceeding the saturated water vapor pressure, and problems caused by dripping of condensed water can be avoided. The occurrence of such problems can be reliably prevented.

Furthermore, since the hollow fiber porous body 1 constituting the humidifying module 10 is composed of thin tubes and has good moldability, the shape and size of the humidifier can be freely set according to the application conditions. The effect is that the applicability is improved accordingly. ■Claim 2
According to the humidifier described above, in addition to the effect described in (1) above, each of the hollow fiber porous bodies 1, 1, . For example, compared to the case where it is formed into a flat plate, the structure has a more compact structure, which ensures a larger contact area with the air and achieves even higher humidification efficiency. can get.

[0026] According to the humidifier according to claim 3, in addition to the effect described in (1) above, a plurality of hollow fiber porous bodies 1, 1, .
Since the substantially flat hollow fiber units 9 consisting of are attached radially around the spindle 2, each of the hollow fiber units 9, 9, . . . is exposed to the outside,
The effect is that the maintainability is improved.

[0027] According to the humidifier according to claim 4, in addition to the effect described in item (1) above, each hollow fiber unit 9 is formed in a curved shape, and the humidifying module 10 in which these hollow fiber units 9 are radially attached to the spindle 2 is provided. Since it takes the form of a rotary blade, it becomes easier to take air into the humidifying module 10 as it rotates, thereby increasing the air blowing effect on the humidifying module 10, thereby achieving the effect that more efficient humidification is possible.

[0028] According to the humidifier according to claim 5, in addition to the effect described in (1) above, each hollow fiber unit 9, 9, . . . formed by winding the hollow fiber porous body 1 in a spiral shape It is attached to the support shaft 2 in a multi-stage manner, and high humidification efficiency can be obtained especially with respect to ventilation in the axial direction of the support shaft 2. Therefore, it can be installed, for example, in the duct of an air conditioner in the axial direction. Since no dedicated space is required for the arrangement, the structure of the device can be simplified or made more compact.

[0029] According to the air conditioner equipped with a humidifier according to claim 6, the humidifier is arranged to be exposed in the ventilation path 51 of the air conditioner, and the conditioned air is actively directed to the humidification module 10.
in contact with each of the hollow fiber porous bodies 1, 1,...,
Since the humidifying module 10 itself is rotated by the dynamic pressure of the air-conditioned air or by an appropriate driving means to further increase the degree of contact with the air, the humidifier can be installed in a compact air conditioner. Although it is a structure, the effect that high humidification efficiency can be obtained can be obtained.

Furthermore, especially when the humidifying module 10 is rotated by an appropriate driving means, it is possible to easily change and adjust the humidification by controlling the rotation, so that the humidity can be adjusted to suit the actual air conditions. It also has the effect of ensuring humidity and realizing more comfortable air conditioning.

Hollow fiber 3 with a small diameter (outer diameter 0.3 to 1.0 mm)
1, fine holes 31c, 31c, etc. (for example, hole diameter 0.1 to 1
．． A water reservoir in which a large number of hollow fiber porous bodies 1 (about 0 μm) are cut into straight tubes of a predetermined length, and these are wound in a spiral shape, and the inner peripheral end 3a of the hollow fiber porous body 1 is formed on the support shaft 2. A pipe-shaped water supply passage 3 is fixed facing the chamber 6 and has its outer circumferential end 3b closed, and is fixed to the support shaft 2 so as to be substantially parallel to the water supply passage 3 at a position below the water supply passage 3. The hollow fiber porous body 1 is configured to be arranged in a spiral manner at predetermined intervals (preferably about 0.6 to 2.0 mm, which is twice the outer diameter of the hollow fiber porous body 1), spanning the disk-shaped receiving plate 14. ing. In this case, each of the hollow fiber porous bodies 1, 1,...
* is communicated with the water supply passage 3 at its upper end, and is closed by the receiving plate 14 at its other end.

The distance between the hollow fiber porous bodies 1, 1, . . . in the radial direction is ensured by the stays 4, and the distance dimension is set to be substantially the same as the distance in the spiral direction. In addition, the water supply passage 3 and the receiving plate 14 are made of an elastic material such as fluororubber or silicone rubber, from the viewpoint of ensuring close contact with the ends of each hollow fiber porous body 1, 1, . It is desirable to form.

Further, the support shaft 2 is rotatably supported at two positions, the upper position of the water supply passage 3 and the lower position of the receiving plate 14, and is rotated at a predetermined speed by an appropriate drive device such as an electric motor. It is designed so that it can be rotated. Furthermore, the water storage chamber 6 having a predetermined capacity for receiving water supply from the water supply pipe 5 is formed inside the upper end portion 2a of the support shaft 2, and the water storage chamber 6 is provided inside the water storage chamber 6. A float 7 is provided that closes the water supply pipe 5 to stop water supply when the water supply pipe 5 is almost full.

[0036] Note that the holes 31c, 31 of the hollow fiber porous body 1
c, . . . are formed by a known method such as a dissolution extraction method or a stretching method, and have a porosity of about 20 to 70%.

According to the humidifier Z1 constructed as described above, the water supplied to the water storage chamber 6 is filled into each of the hollow fiber porous bodies 1, 1, . . . via the water supply passage 3. Furthermore, when the humidifying module 10 is rotated at a predetermined speed in this state, centrifugal force acts on the water in the water supply passage 3, and the water is pushed into each hollow fiber porous body 1, 1, etc. by this centrifugal force. Receive the power that makes you feel For this reason, each of the hollow fiber porous bodies 1, 1,...
The filling of water into the interior can be made more reliable. Therefore, the water evaporates sequentially from the outer circumferential side due to the vapor pressure difference with the outside air, and the generated water vapor is transferred to each hole 31c, 31c.
, . . , into the outside air to moderately humidify the outside air.

In this case, humidification module 1 of humidifier Z1
In addition to the hollow fiber porous bodies 1, 1, . . 0 having sufficient spacing for ventilation, the humidifying module
Due to the synergistic scavenging effect of the rotary rotation of the hollow fiber porous bodies 1, 1, . Localized humidification (ie, localized vapor pressure increase) around the area is prevented. As a result, the release of water vapor from each of the hollow fiber porous bodies 1, 1, etc. is performed as stably and efficiently as possible, and diffusion and mixing into the air is promoted, thereby ensuring higher humidification efficiency. It is something that will be done.

Furthermore, since the humidifying module 10 is composed of small-diameter hollow fiber porous bodies 1, 1, etc., if the volume of the humidifier Z1 is constant, for example, the humidifying module 10 can be The volumetric efficiency is improved compared to a membrane-like structure or a relatively large-diameter hollow porous tube as in the above-mentioned known example, and the device can be made more compact. becomes.

Furthermore, this humidifier Z1 has hollow fiber porous bodies 1, 1, . . . which have a function of allowing only water vapor to pass through the membrane.
Since the hollow fiber porous body 1 is made of fluorine, it is possible to achieve more hygienic humidification without causing bacteria and impurities contained in the water to be released into the air together with water vapor. Since it is constructed using a resin as a base material, it also has the advantage that hard components contained in moisture, that is, scale, are prevented from adhering to the hollow fiber porous body 1 as much as possible.

FIG. 3 shows a humidifier Z1' as a modification of the first embodiment. This humidifier Z1' is different from the humidifier Z1 of the above embodiment in that each hollow fiber porous body 1, 1, .
・While the upper end was attached to the water supply passage 3 formed by winding in a spiral shape, each of the hollow fiber porous bodies 1, 1,
... are arranged in advance in a spiral shape, and their upper ends are attached to the substantially hollow disk-shaped water supply chamber member 8 fixed to the support shaft 2 so as to face the internal space 8a thereof. . Further, the internal space 8a of the water supply chamber member 8 is communicated with the water storage chamber 6 of the support shaft 2. Therefore, this humidifier Z1' can be expected to have the same effects as the humidifier Z1 described above.

Second Embodiment FIGS. 4 and 5 show a humidifier Z2 according to an embodiment of the invention as set forth in claims 1 and 3 of the present application. This humidifier Z2 comprises a humidifying module 10 using hollow fiber porous bodies 1, 1, . The point that water is evaporated and humidified by the difference in vapor pressure between the inside and outside of the hollow fiber porous body 1 is the same as that of the first example above, but
This embodiment is different from the first embodiment in that it has a specific structure of the humidifying module 10.

That is, in this embodiment, an upper support rod 11 of a predetermined length is provided on the upper end side of a rotatably supported support shaft 2, and the upper support rod 11 has a predetermined length and a water storage chamber inside the support shaft 2. 6, and a rod-shaped lower support rod 12 is provided on the lower end side, and a large number of hollow fiber porous bodies 1 are provided so as to straddle between the pair of upper and lower support rods 11, 12. ,1,...
are arranged at a predetermined interval from each other to constitute one hollow fiber unit 9. A plurality of such hollow fiber units 9 are provided radially around the support shaft 2 at predetermined intervals to constitute one humidifying module 10. In FIG. 4, reference numeral 13 is a water tank provided at the upper part of the water supply pipe 5, and the inflow state of the water introduced into the water tank 13 is controlled by a float 7 placed in the water storage chamber 6. Water is supplied to each hollow fiber porous body 1, 1, . . . side through the upper support rod 11 of each hollow fiber unit 9, 9, .

When configured as in this embodiment, efficient humidification performance can be obtained by the same action as in the first embodiment, but in addition, each hollow fiber unit 9
, 9, . . . are exposed to the outside, maintenance and inspection thereof are easy, which is advantageous in terms of maintainability of the device.

Third Embodiment FIG. 6 shows a humidifier Z3 according to an embodiment of the invention as set forth in claims 1 and 4 of the present application. This humidifier Z3 is
In the second embodiment, each of the hollow fiber units 9, 9, .
The upper support rod 11 and the lower support rod 1 are formed into a curved shape.
A plurality of hollow fiber porous bodies 1, 1, . It consists of In this case, by arranging the adjacent hollow fiber units 9, 9, etc. in the same direction, the humidifying module 10 as a whole assumes a rotary blade shape.

According to the humidifier Z3 of this embodiment configured as described above, water is supplied into each hollow fiber porous body 1, 1, . . . while the humidifying module 10 is rotated around its supporting shaft 2. As in the case of the second embodiment, scavenging air around each of the hollow fiber porous bodies 1, 1, etc. is performed efficiently, and effective humidification can be performed under constantly stable vapor pressure. However, in this embodiment, since each of the hollow fiber units 9, 9, . It can be taken inside. As a result, the operation effect around the hollow fiber porous bodies 1, 1, . This also has the advantage that when the humidification efficiency is kept constant, the surface area of each hollow fiber unit 9 can be reduced to the extent that the scavenging action is promoted, thereby promoting compactness.

Fourth Embodiment FIG. 7 shows a humidifier Z4 according to an embodiment of the invention as set forth in claims 1 and 5 of the present application. Humidifier Z of this example
4 is a plurality of hollow fiber units 9, 9, . The humidifying module 10 is installed in multiple stages at predetermined intervals in the direction.
It consists of Then, each hollow fiber unit 9, 9
, . . . both ends of the hollow fiber porous body 1 are fitted into the support shaft 2, and water is supplied into each of the hollow fiber porous bodies 1, 1, . . . from one end side. It looks like this.

In the humidifier Z4 of this embodiment, the hollow fiber porous body 1 of each hollow fiber unit 9, 9, .
Of course, it is possible to efficiently humidify by increasing the scavenging effect of the surrounding air, but in addition, due to its structure, the highest humidifying effect can be obtained especially when ventilation is axially directed. Therefore, for example, it is possible to obtain a high humidification effect by inserting the humidifier Z4 coaxially into the ventilation duct of an air conditioner. As a result, there is no need to secure a dedicated space for the humidifier, and the advantage is that the air conditioner as a whole can be made more compact or have a simpler structure, especially if it is installed alongside an air conditioner. It is something that can be done.

Fifth Embodiment FIG. 8 shows an air conditioner 50 equipped with a humidifier Z according to an embodiment of the invention set forth in claim 6 of the present application. This air conditioner 50 has one of the humidifiers Z1 to Z4 of the above-mentioned embodiments incorporated therein as a humidifier Z, and has an inlet port 56 opened at the front surface of the casing 57 and opened at the lower front surface. A heat exchanger 52 and a fan 53 are arranged one behind the other in a ventilation passage 51 that extends in a curved shape toward the air outlet 55, and a heat exchanger 52 and a fan 53 are disposed in front and behind each other. A substantially semicircular recess 58 is formed in the downstream portion 54a in a direction substantially perpendicular to the ventilation path 51, and any of the humidifiers shown in the above embodiments is rotatably arranged therein. has been done. In this arrangement state of the humidifier Z, the upper part thereof is exposed in the ventilation passage 51. Further, the humidifier Z may be configured to simply be rotatable without providing any dedicated drive means, or may be configured to include, for example, a motor as a dedicated drive means and be forcibly rotated by this.

[0050] In the air conditioner 50 having such a configuration,
When this is operated and air flows through the ventilation passage 51,
When the air comes into contact with each of the hollow fiber porous bodies 1, 1,... of the humidifying module 10 of the humidifier Z, the water in the hollow fiber porous body 1 is sequentially evaporated due to the difference in vapor pressure between the inside and outside, and this becomes ventilation. It is mixed and diffused into the air flow in the passage 51 to moderately humidify the air.

In this case, especially in this embodiment, since the humidifier Z is rotatable, for example, if the humidifier Z is not equipped with a driving means, it can be rotated by the dynamic pressure of the air flow, or if it is equipped with a driving means, it can be rotated by the dynamic pressure of the air flow. It is rotated appropriately by the driving force of the driving means and the dynamic pressure of the air. As a result, even if only about the upper half of the humidifier Z is exposed to the ventilation passage 51 as in this embodiment, as it rotates, the entire area sequentially faces the ventilation passage 51, and almost all the scavenging air around it is exposed to the ventilation passage 51. This is done evenly and effectively, and each hollow fiber porous body 1, 1, .
・The vapor pressure around the area is kept almost constant, and stable and high-level humidification is achieved.

Furthermore, since only a part of the humidifier Z is exposed to the ventilation path 51, the increase in ventilation resistance due to the installation of the humidifier Z is extremely small, and the original air conditioning performance is maintained. Not only does this have almost no effect on the air conditioner, but there is no need to particularly consider the installation space for the humidifier, so there is an advantage that the air conditioner 50 itself can be made compact despite the installation of the humidifier Z.

Furthermore, especially when the humidifier Z is forcibly rotated by an appropriate driving means,
By controlling the rotation, it is possible to easily change and adjust the scavenging action, that is, the humidification action, of the surrounding air of each hollow fiber porous body 1, 1, etc., so it is possible to easily select the optimal humidification for the surrounding air conditions. It is possible to obtain more comfortable heating and cooling characteristics.

[0054] This humidifier Z has a fan 5 as described above.
It is not limited to those placed downstream of 3.
In short, it is sufficient that it faces the ventilation path 51, for example, as shown in Figure 8.
It is also possible to provide it in the upper part 54b of the passage wall 54 located immediately downstream of the heat exchanger 52, as shown by the chain line in FIG.
