DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier of the drip pervaporation type and an air conditioner provided with the humidifier on the outlet side of a blower.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional air conditioner which performs humidification through a drip-penetration type humidifier. The air conditioner 70 has a heat exchanger 72 that can cool or heat air through a refrigerant or a brine in a tube, and a blower 73 that pressurizes air whose temperature has been adjusted.
Is a separate type air conditioner in which a blower 73 is disposed above the air conditioner. Further, the discharge side (upper surface) of the heat exchanger 72
A humidifier 75 of a drip-penetration type is attached to the humidifier, so that air whose humidity is controlled in addition to temperature control can be supplied. In the humidifier 75, a humidifier 77 installed on the surface of the heat exchanger 72 is supplied with water by a water supply system 76 having a pressure reducing valve, an electromagnetic valve, and the like, and the humidifier 77 containing the moisture reaches a predetermined temperature. Humidified air passes through. Then, the air is supplied to the outside by the blower 73.

[0003]

SUMMARY OF THE INVENTION A humidifier of the drip pervaporation type is a humidifier that humidifies by passing an air flow, does not require electric power, and is a thin type and low pressure loss package such as a separate type. Suitable for incorporating into air conditioners. However, when the drip-vaporization type humidifier is used for a package air conditioner of a ceiling storage type or a ceiling type, some problems occur. That is, the packaged air conditioner of the ceiling storage type or the ceiling suspension type is assembled as compactly as possible so that it can be installed in a narrow space. In particular, the blower 73 and the heat exchanger 72 are arranged so as to be horizontal, and Is made thinner. For this reason, when a drip pervaporation type humidifying device is attached to the discharge side of the heat exchanger 72, unlike a floor-mounted package air conditioner in which a heat exchanger and a blower (fan) are arranged vertically, depending on the wind speed passing through the humidifying device. Reaches the motor that drives the blower 73 without dripping water or water droplets. Therefore, it is necessary to upgrade the type of the jacket of the motor that drives the blower 73 from a conventional open type to a drip-proof type or a rain-proof type. As a result, the size of the outer casing of the motor becomes large, which increases the size of the packaged air conditioner and causes a significant design change. Also, increasing the grade of the motor increases the cost.

[0004] A package air conditioner of a ceiling storage type or a ceiling suspension type is compact, and a heat exchanger 72 is provided with a blower 73.
The distance to is short. Therefore, when the humidifier 75 of the drip-penetration type is installed between the heat exchanger 72 and the blower 73, it is necessary to secure a space for routing pipes for supplying water to the humidifier 77 of the humidifier 75. Therefore, it is necessary to significantly change the arrangement position of each device inside the air conditioner. From this point as well, it is difficult to mount the drip pervaporation type humidifier 75 between the heat exchanger 72 and the blower 73 in a ceiling-mounted or ceiling-mounted package air conditioner.

[0005] It is also possible to attach a drip pervaporation type humidifier to the outlet of the blower 73. However,
If the air blown out from the blower 73 is directly guided to the humidifier 75, water splashes will occur beyond the wind speed that can be processed by the humidifier. The water splash causes air mixed with moisture to be supplied into the room, and furthermore, water droplets adhere to the duct to cause water leakage or stains on the ceiling. If the wind speed is adapted to the humidifier, the size of the air outlet must be increased and the area of the humidifier must be increased, so that the air conditioner is large and expensive.

As shown in FIG. 5, a part of air supplied from an outlet of a blower 73 is sucked by a boost fan 78, and a humidifier installed in a duct separate from a discharge duct 79 of an air conditioner. It is also possible to supply air to the discharge duct 79 at an appropriate wind speed and return the air humidified by the humidifier 75 to the discharge duct 79. However, in such a system, equipment and components such as a pipe and a boost fan 78 for guiding a part of the air supplied from the outlet of the blower 73 to the humidifier 75 are required, so that the air conditioner is large. And causes a rise in cost.

Therefore, in the present invention, a dripping pervaporation type that can be assembled in an air conditioner such as a ceiling storage type or a ceiling suspension type without accompanying a design change such as raising a protection class of a motor for a fan (blower). The purpose of the present invention is to provide a humidifying device. In particular, it is an object of the present invention to provide a compact, thin, and easy-to-install humidifier suitable for ceiling-mounted and ceiling-mounted air conditioners at low cost without water splashing. Another object of the present invention is to provide an air conditioner which is compact, thin, and particularly suitable for a ceiling storage type and a ceiling suspension type equipped with a humidification mechanism by incorporating the humidification device.

[0008]

In order to solve the above-mentioned problems, a humidifier according to the present invention is provided with a panel-type member having a restricted aperture ratio in an introduction passage for supplying air to a humidifying section of a drip pervaporation type. The humidifying section is converted to an appropriate wind speed which can be processed by the panel type member. That is, the humidifying device of the present invention has a humidifying section of a drip-penetrating type and an introduction path for guiding air to the humidifying section, and a panel-type member having a restricted aperture ratio is installed in the introduction path. .

In the humidifying device of the present invention, the flow rate of the air supplied to the humidifying section flowing through the introduction path can be made slower than the flow rate of the air flowing around the humidifying section by the panel type member having a limited aperture ratio. Therefore, even if it exceeds the maximum use wind speed of the humidifying unit outside the introduction path, it can be converted to a wind speed that can be processed by the humidifying unit by the panel-type member. For this reason, even if the surrounding wind speed is high, humidified air can be supplied without water splashing. Therefore, a humidifier provided with a drip-penetration-type humidifier can be attached to the blowing side of the blower of the air conditioner. That is, the humidifier of the present invention can be arranged on the blowout side of a blower of an air conditioner having a heat exchanger capable of controlling the temperature of air and a blower that blows out the air whose temperature is controlled by the heat exchanger. In addition, it is possible to provide an air conditioner in which a humidifier of a drip-penetration type is provided on the outlet side.

As described above, the humidifier of the present invention can be used without causing water splashing by being attached to the blower side of the air conditioner blower. Therefore, the humidifier is a ceiling storage type or ceiling type air conditioner equipped with a humidifier. However, moisture or water droplets from the humidifier do not affect the drive motor of the blower.
Therefore, a small-sized and low-cost motor can be used without upgrading the protection system of the drive motor. Further, unlike the case where the humidifier is attached between the heat exchanger and the blower, it is not necessary to change the arrangement position of the piping for supplying water to the humidifier and the equipment inside the air conditioner. Therefore, by using the humidifying device of the present invention, even in a compact air conditioner such as an air conditioner of a ceiling storage type and a ceiling suspension type, the size does not increase, and an increase in weight and a rise in cost can be prevented. Further, a humidifying mechanism can be added with almost no design change.

Further, since the humidifier of the present invention has a panel-type member for adjusting the wind speed of air, a part of the air is guided from the air outlet of the air conditioner to the humidifier, or the outlet duct is widened to reduce the wind speed. From these points, it is possible to provide an air conditioner in which a humidifier is installed in a part of a duct that is more compact, lighter, and lower in cost, without having to lower it. According to such an air conditioner, only the wind speed passing through the humidifier can be controlled, and the pressure loss applied to the panel-type member can be reduced.

Further, even if the humidifying device of the present invention is arranged on the blowing side of a blower of an air conditioner, there is no occurrence of water splash.
The generation of air mixed with moisture can be prevented. For this reason, it is possible to realize an air conditioner particularly suitable for a compact ceiling storage type and a ceiling suspension type, which does not cause problems such as water droplets adhering to the duct and causing water leakage and stains on the ceiling. Further, since it is not necessary to increase the size of the air outlet and to increase the area of the humidifying material in order to adapt the wind speed to the humidifying device, it is possible to avoid a large and expensive air conditioner.

As the panel type member, a mesh member such as lath metal having sufficient durability against the wind speed of the air supplied to the introduction path can be used. If such a mesh-like mesh member is used, the wind speed of air can be adjusted and the wind speed supplied to the humidifying unit can be made uniform, so that the humidifying capacity of the humidifying unit can be sufficiently exhibited. In addition, if the mesh member having a fine mesh is used as a panel-type member, it also functions as a filter for dust, so that there is an advantage that clogging of the humidifying portion can be prevented.

The mesh member can adjust the aperture ratio in accordance with the number of meshes, and can control the wind speed of the introduction path according to the air volume of the blower. By arranging the mesh member at an angle to the introduction path, the substantial aperture ratio can be further controlled even if the mesh members have the same number of meshes. Therefore, the wind speed of the introduction path can be set optimally. For this reason, by adjusting the installation angle of the mesh member with respect to the introduction path, it is possible to obtain an intermediate aperture ratio that cannot be obtained by directly controlling the number of meshes, and to meet specifications such as the performance of the air conditioner. On the other hand, a humidifier having versatility can be realized, and by using the humidifier of the present invention, an air conditioner having a humidifier with various capabilities can be provided.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a humidifier and an air conditioner according to the present invention. FIG. 1 shows a schematic configuration of an air conditioner in which a drip pervaporation type humidifier is incorporated as viewed from the side. FIG. 2 is an enlarged view of a peripheral portion of the air conditioner to which the humidifier is attached. FIG. 3 shows how the humidifier is attached to the air conditioner. As shown in these figures, the air conditioner 1 of the present embodiment is a ceiling-suspended air conditioner in which a drip-penetration type humidifier 3 is externally attached to an air conditioner 2. The guided temperature-controlled air passes through the humidifier 3 and is humidified, and then supplied to a room or the like.

The air conditioner 2 is provided with a heat exchange unit 4 capable of controlling the temperature of the air passing therethrough, and a blower unit 5 for blowing out the air whose temperature is controlled by the heat exchange unit 4. And is suspended from a ceiling or the like by a support 41. The heat exchange unit 4 and the blower unit 5 are arranged horizontally, and the distance between them is set to be short, so that the entire air conditioner 2 is thin and compact. The heat exchanging section 4 of the present example includes a heat exchanger 7 composed of a coil for cooling or heating through a refrigerant or the like.
And a drain pan 8 installed below the heat exchanger 7 to collect the drain generated in the heat exchanger 7. The blower unit 5 includes two blowers 9 and 10 using a sirocco fan or the like.
0 is an open double-shaft motor 11 installed between them.
It is adapted to be driven by.

As shown in detail in FIG. 1, in the air conditioner 1 of this embodiment, the humidifier 3 and the air conditioners 2 and the humidifier 3 are horizontally arranged on the side of the blowout ports 12 and 13 of the blowers 9 and 10. It is attached so that. Humidifier 3
Is a humidifying material 25 stored in a stainless steel frame or the like.
And a humidifying unit 21 of a drip-penetrating type that humidifies by passing airflow through the humidifying material 25, and a blower 9
And a humidifier main body 3a having a panel-type member 31 installed in the introduction path 22 to guide a part of the air supplied from the humidifier 21 to the housing 6 of the air conditioner 2.
Are housed in a housing 24 that leads to The housing 24 has left and right openings on the supply side and the discharge side so that air from the air conditioner 2 can be blown out from the front blowout port 27, and forms a blowout duct of the air conditioner 1. The introduction path 22 of the humidifier body 3a occupies a part of the blow-out duct (housing) 24, and the blowers 9 and 10
A part of the air blown out from the humidifier goes to the humidifying section 21 through the introduction path 22, and after being humidified, returns to the blowout duct 24 and is mixed with the remaining air blown out from the blowers 9 and 10. For this reason, air of appropriate humidity can be supplied to the room or the like from the outlet 27.

In the humidifier body 3a of this embodiment, the supply of water to the humidifying material 25 of the humidifying section 21 is controlled by a controller 26 attached to the outer wall of the housing 24. As a means for supplying water to the humidifying material 25, a water supply unit in a conventional air conditioner shown in FIG. 4 can be employed.

The air supplied to the humidifying section 21 through the introduction passage 22 at an appropriate wind speed passes through the humidifying section 21.
In the humidifier 3 of this example, a panel-type member 31 having a limited aperture ratio is installed obliquely in the introduction path 22. The panel-shaped member 31 has a predetermined mesh number, and
A mesh member made of lath metal or the like having sufficient durability against the wind speed supplied from No. 3 is used. The installation position of the panel-shaped member 31 is near the entrance of the introduction path 22. In this example, the lower end of the panel-shaped member 31 is fixed to the lower edge portion of the outlets 12 and 13, and the upper end is fixed to the upper end of the humidifier 25, and is oblique to the introduction path 22. It is installed to become.

The air supplied to the humidifying section 21 is supplied to the introduction path 2
2 can be controlled by a substantial aperture ratio (effective aperture ratio ε ′ [%]) of the panel-type member 31 provided in the second member 2. The effective aperture ratio ε ′ can be described as follows based on the installation angle θ of the panel-type member 31 and the number M of meshes of the panel-type member 31. The wire diameter of the panel-type member 31 is d [mm], the aperture is A [mm], the aperture ratio when the panel-type member 31 is installed perpendicular to the introduction path 22 is ε [%], On the other hand, the effective aperture ratio ε ′ [%] when the panel-type member 31 is disposed obliquely (at an angle θ) is obtained by the following equations (1), (2), and (3).

A = 25.4 / (M−d) (1) ε = {A / (A + d)} ² × 100 (2) ε ′ = {A / (A + d)} ×} A · sin θ / (A · sin θ + d)｝ × 100 (3) Each of the panel-type members 31 having the number of meshes M of 30, 40, and 50 was set in the introduction path 22 at angles θ of 35 ° and 90 °. The effective aperture ratio ε ′ at that time is as follows.

The effective aperture ratio epsilon 'A diameter opening angles θ mesh number M th d 55 90 30 0.63 0.22 46 35 30 0.63 0.22 43 90 40 0.42 0.22 41 90 50 0.33 0.18 35 35 40 0.42 0.22 33 35 50 0.33 0.18 Thus, as the panel-type member 31, the number of meshes M is 3
Using standard products of 0, 40, and 50, the effective aperture ratio ε ′ of the panel-shaped member 31 can be set to be variable from 33 to 55 by simply changing the installation angle θ with respect to the introduction path 22. From the above results, even if the panel-type member 31 has the same mesh number M, the panel-type member 3
It can be seen that various effective aperture ratios ε ′ can be obtained by adjusting the installation angle θ with respect to the first introduction path 22. For this reason, by adjusting the installation angle θ of the panel-type member 31 with respect to the introduction path 22, an intermediate aperture ratio that cannot be obtained by directly controlling the number of meshes M can be obtained, and the capacity of the air conditioner can be obtained. It is possible to realize a humidifier having versatility with respect to specifications such as the above, and it is possible to provide an air conditioner having a humidifier with various capabilities by using the humidifier.

In the humidifying device 3 of this embodiment, a part of the air supplied from the outlets 12 and 13 of the blowers 9 and 10 is guided to the panel-type member 31 having a predetermined opening ratio. The flow velocity of the air is reduced according to the effective aperture ratio ε ′ of the member 31. Further, in the humidifying device 3 of this example, since the mesh-shaped, that is, the mesh-shaped panel-shaped member 31 is used, the flow velocity of the air passing through the panel-shaped member 31 is made uniform. As described above, in the humidifier 3 of the present embodiment, even if the wind speed exceeding the maximum use wind speed of the humidifier 25 is supplied from the air conditioner 2 to the humidifier 3, the processing capacity of the humidifier 25 is reduced by the panel-type member 31. It can be converted to a matched uniform wind speed. For this reason, the humidifying device 3 of this example can supply humidified air without water splash even if the wind speed supplied to the introduction path 22 is high, and the humidifying device 3 supplies the air to the blowout sides of the blowers 9 and 10 of the air conditioner. Can be assembled. In other words, it is possible to provide an air conditioner in which a drip pervaporation type humidifier is provided on the blowing side of the blowers 9 and 10.

Further, the humidifier 3 of this embodiment can be mounted on the blow-out sides of the blowers 9 and 10 of the air conditioner 1 and used without water splashing. Even in an air conditioner, moisture or water droplets from the humidifier do not adversely affect the motor 11 for driving the blowers 9 and 10. Therefore, a small and low-cost motor can be used without upgrading the drive motor 11. Further, as in the case where a humidifying device is installed between the heat exchanging unit 4 and the air blowing unit 5, the humidifying unit is installed in a pipe for supplying water to the humidifying material 25 or inside the air conditioner 2 such as the heat exchanger 7 and the drain pan 8. It is not necessary to change the arrangement position of each device. For this reason, even compactly integrated air conditioners such as ceiling-mounted and ceiling-suspended type air conditioners do not increase in size, can prevent an increase in weight and a rise in cost, and furthermore, hardly change the design. A humidifying mechanism can be added to the device.

Further, the humidifier body 3a of the humidifier 3 of the present embodiment.
Is provided with a panel-type member 31 for adjusting the wind speed, so that it can be installed in a part of the blow-out duct 24 of the air conditioner 1. For this reason, it is more compact and lightweight, and
An air conditioner having a low-cost humidifying function can be provided. By attaching the humidifier main body 3a to a part of the air outlet duct 24 of the air conditioner 1 in this way, it is possible to control only the wind speed passing through the humidifier 21 and reduce the pressure loss applied to the panel-type member 31. .

Further, even if the humidifying device 3 of this embodiment is arranged on the blow-out side of the blowers 9 and 10 of the air conditioner 2, since no water splash occurs, it is possible to prevent the generation of air mixed with moisture. Can be. Therefore, the air outlet duct 2 of the air conditioner 1
An air conditioner which is particularly suitable for a compact ceiling storage type and a ceiling suspension type can be realized which has no troubles such as water leaks due to water droplets adhering to 4 or the like and stains on the ceiling. Further, in order to adjust the wind speed supplied to the humidifying section 21 to the humidifying capacity of the humidifying section 21, it is not necessary to increase the size of the blow-out duct 24 or to increase the area of the humidifying material 25. Can be prevented from becoming large and expensive.

In the humidifying device 3 of this embodiment, since a mesh-like member having a fine mesh is used as the panel-shaped member 31, the wind speed can be adjusted and the wind speed can be made substantially uniform. Therefore, the air having a uniform wind speed is supplied to the humidifying material 25 of the humidifying device 3, and the humidifying ability of the humidifying material 25 can be sufficiently exhibited. In addition, since the mesh member having a fine mesh is used as the panel-shaped member 31, it also functions as a filter for dust.
It is also possible to prevent the humidifying material 25 from being clogged due to dust contained in the air.

The panel-type member 3 having a predetermined aperture ratio
1 is not limited to lath metal, but may be any as long as it has sufficient durability against the wind speed of the air supplied to the introduction path 22. For example, when a panel member having a large aperture ratio is required, a punching metal or the like can be used. Also, if the installation angle θ of the panel-type member 31 with respect to the introduction path 22 can be adjusted without completely fixing the panel-type member 31, the panel-type member 31 can be measured while actually measuring the flow rate of the air supplied to the humidifying material 25. Can be adjusted. The mechanism for adjusting the installation angle θ of the panel-type member 31 may be any mechanism.
A screw and a spring may be used to adjust the installation angle θ of the panel-type member 31 according to the screwing amount of the screw. Further, in this example, one panel-type member is provided in the introduction path 22, but may be two or more. Also, by arranging panel-type members having different aperture ratios on top of each other or by displacing panel-type members having the same aperture ratio,
It is of course possible to control the effective aperture ratio.

[0029]

As described above, in the humidifier of the present invention, a panel-type member having a restricted aperture ratio is provided in an introduction path for supplying air to a drip-penetration-type humidification unit. The wind speed is adapted to match the processing capacity of the humidifier. For this reason, even if the surrounding wind speed is high, the humidified air can be supplied without water splashing, so that an air conditioner provided with a drip-penetrating vaporizing type humidifier provided on the blowing side of a blower of the air conditioner is provided. it can.

The humidifier of the present invention can be mounted on the blower side of the air conditioner and used without water splashing. Therefore, the humidifier is a ceiling-mounted type or ceiling-mounted type air conditioner equipped with a humidifier. Also, it is possible to prevent moisture or water droplets from the humidifier from adversely affecting the drive motor of the blower. For this reason, a small and inexpensive motor can be used without upgrading the protection system of the drive motor, and the humidifier is installed in the humidifier, such as when a humidifier is installed between the heat exchanger and the blower. It is not necessary to change the arrangement position of each device such as a pipe for supplying water and a heat exchanger installed inside the air conditioner. Therefore, by using the humidifying device of the present invention, even in a compact air conditioner such as an air conditioner of a ceiling storage type and a ceiling suspension type, the size does not increase, and an increase in weight and a rise in cost can be prevented. Further, a humidifying mechanism can be added with almost no design change.

Further, since the humidifier of the present invention has a panel-type member for adjusting the wind speed of the air, it can be installed in a part of the air outlet duct of the air conditioner. For this reason,
It is possible to realize a more compact and lightweight air conditioner having a low-cost humidifying function. Further, by installing the humidifier in a part of the blow-out duct, only the wind speed passing through the humidifier can be controlled, and the pressure loss applied to the panel-type member can be reduced.

Further, even if the humidifying device of the present invention is arranged on the blow-out side of the blower of the air conditioner, there is no water splash, so that it is possible to prevent the generation of air mixed with water. For this reason, it is possible to realize an air conditioner particularly suitable for a compact ceiling storage type and a ceiling suspension type, which does not cause problems such as water droplets adhering to the duct and causing water leakage and stains on the ceiling.
