Description

  The present invention relates to a humidified air transport duct and an air conditioner, and more particularly to a humidified air transport duct and an air conditioner having the humidified air transport duct.

  As a first prior art, a non-water-supply humidifying means that uses moisture in the outside air as humidified water is installed in the outdoor unit as two non-water-supply humidifying units, and by switching alternately between the moisture absorption mode and the humidification mode, There is known an air conditioner with a humidifying function of humidifying the air (see, for example, Patent Document 1).

  As a second prior art, one air flow passage provided with a blower, the other air flow passage provided with a blower and a heater, and an adsorbent that alternately enters into each air flow passage while rotating. The air that has been adsorbed by the adsorbent through one air flow passage is exhausted to the outside of the room, and the humidified air that has evaporated the water adsorbed by the adsorbent through the other air flow passage into the room. There is known a humidifier that sends and humidifies the room (for example, see Patent Document 2).

  As a third prior art, in a coaxial double pipe projecting from a humidifier, the temperature is raised by the adsorption heat of the adsorbent as a structure in which air after regeneration processing of the adsorbent is blown inside and air after drying is blown outside. There is known a humidifier that suppresses condensation of the air after the inner regeneration process by the dried air after the drying process (see, for example, Patent Document 3).

Japanese Patent No. 3132940 (3rd page, FIG. 4) Japanese Patent No. 3559421 (page 4-5, FIG. 1) Japanese Patent No. 3172644 (page 4, FIG. 7)

However, the first prior art has the following problems.
(A) In two non-feed water humidification units, since the humidification mode and the humidification mode are switched alternately, humidified air can be always supplied to the room, but the two units are equipped. This increases the manufacturing cost.
(Ii) When switching modes, it is necessary to switch between the four-way solenoid valve, the two two-way solenoid valves, and the two pumps, and to turn on / off the two heaters. And the configuration and control are complicated.
(Iii) Furthermore, since the heater has thermal inertia, the time loss during mode switching is large. That is, even if the heater is turned off and switched to the moisture absorption mode, high temperature air is sent until the heater is cooled, so moisture absorption is not performed. On the other hand, even if the heater is turned on and switched to the humidification mode, the heater temperature rises. Is not humidified.

The second prior art has the following problems.
(E) Rotating the adsorbent, moisture in the outside air adsorbed in one air flow passage is evaporated in the other air flow passage and sent to the room, so it is continuously humidified without switching the air passage Although air can be supplied indoors, in order to rotate the adsorbent installed across the two air flow passages, there is no choice but to install a gap in the vicinity of the adsorbent. Leakage occurs.
(O) In addition, since the blower is installed outside, the influence of noise generated from the blower into the room can be reduced, but the direction of the air flow by the two blowers is the same, Adsorption and adsorption in the adsorbent are performed in the parallel direction, so that the adsorption / adsorption efficiency is lowered and a sufficient amount of humidification cannot be obtained.

Further, the third prior art has the following problems.
(Or) Since the dried air heated by the adsorption heat is blown outside the coaxial double pipe, the temperature drop of the inner regenerated air can be suppressed slightly, but the heat generated by the adsorption heat is not much. Since it is not large, the temperature increase range of the air after the inner regeneration treatment is at most about 10 to 20 ° C.
(G) In addition, since the heat transfer coefficient between the outer side and the inner side of the double pipe is improved by flowing air after the drying treatment on the outer side, the inner air is cooled by the outer air, which is sufficient. A dew condensation suppressing effect cannot be obtained.

  The present invention has been made in order to solve the above-described problems, has a simple configuration and control, prevents the occurrence of air leakage and a decrease in adsorption / adsorption efficiency, and is compact while exhibiting a dew condensation suppressing effect. It is an object of the present invention to provide a humidified air conveying duct and an air conditioner that can supply humidified air continuously by a simple operation.

(1) A humidified air conveyance duct according to the present invention includes a compressor, an outdoor heat exchanger, and an outdoor unit that incorporates an expansion valve, and an indoor heat exchanger that constitutes the refrigeration unit. A humidified air transfer duct that communicates the humidifier and the indoor unit in an air conditioner having an indoor unit and a humidifier integrally installed on an upper portion of the outdoor unit, the air of the humidifier A double pipe having an inner pipe connected to the exhaust port, an outer pipe surrounding the inner pipe, and a pair of lids installed at end portions of the outer pipe to close a gap between the inner pipe and the inner pipe The structure is characterized in that static air is sealed in a space formed by the inner tube, the outer tube, and the pair of lids, and a small hole is provided in at least one of the pair of lids. .

(2) Further, an air conditioner according to the present invention includes a compressor constituting an refrigeration unit, an outdoor heat exchanger, and an outdoor unit incorporating an expansion valve;
An indoor unit with a built-in indoor heat exchanger constituting the refrigeration unit;
A humidifier integrally installed at the top of the outdoor unit;
The humidified air conveyance duct according to (1),
It is characterized by comprising.

(I) Therefore, the humidified air carrying duct according to the present invention (same as the indoor / outdoor connecting duct) has a double pipe structure, and the temperature between the inner pipe and the outer pipe is lower than that of still air (outside air) or the outside air. By supplying a part of the high regeneration outlet air, it is possible to obtain an effect of having high heat insulation performance and suppressing dew condensation in the inner pipe.
(Ii) Further, in the air conditioner according to the present invention, since the humidifier is installed integrally with the upper part of the outdoor unit, the humidifier can be installed in a minimum space, and the humidifier and the humidified air conveyance are provided. The effect of the duct is obtained.

And the 1st layer 10 is divided into two by the 1st air way partition plate 11 which passed through the axis center and was arranged in the east-west direction, and is equivalent to the semicircular 1st north air way (the 1st regeneration air air way). ) 10a and a first south air passage (corresponding to a first adsorption air air passage) 10b. Similarly, the fourth layer 40 is divided into two by a fourth air passage partition plate 41 into a fourth north air passage (fourth adsorption air air passage) 40a and a fourth south air passage (corresponding to the fourth regeneration air air passage) 40b.

At this time, the second air passage partition plate 21 and the third air passage partition plate 31 are disposed in the same plane and are in close contact with the moisture adsorption means 2. On the other hand, the first air path partition plate 11 and the fourth air path partition plate 41 are disposed in the same plane, and are orthogonal to the second air path partition plate 21 and the third air path partition plate 31 in plan view. Arranged in phase.

(Air path switching damper)
An upper air path switching damper 50 is rotatable between the first layer 10 and the second layer 20, and a lower air path switching damper 60 is rotatable between the third layer 30 and the fourth layer 40 around the axis. (Hereinafter, both may be collectively referred to as “airway switching damper”).
The upper air path switching damper 50 is divided into four fan ranges (1/4 circle) by upper damper partition plates 51, 51 arranged in a cross shape. Then, the pair of opposing fan-shaped ranges are closed to form upper damper closed portions 50b and 50c, and the upper damper ventilation that can be ventilated into the pair of fan-shaped ranges sandwiched between the upper damper closed portion 50b and the upper damper closed portion 50c. Portions 50a and 50d are formed.
Similarly, the lower air path switching damper 60 is divided into four by lower damper partition plates 61, 61 arranged in a cross shape, and a pair of opposing fan-shaped (1/4 circle) lower damper closing portions 60b, 60c and a pair of Fan-shaped (1/4 circle) lower damper vents 60a, 60d.
At this time, in a plan view, the upper damper closing portions 50b and 50c and the lower damper ventilation portions 60a and 60d have the same phase, and the upper damper ventilation portions 50a and 50d and the lower damper closing portions 60b and 60c have the same phase. While maintaining this relationship, the upper air path switching damper 50 and the lower air path switching damper 60 rotate (this will be described in detail separately).

(Wind path)
A first intake port (corresponding to an adsorbed air intake port) 13 is formed in the first south air passage 10 b of the first layer 10, and outside air is sucked into the first intake port 13 by the adsorbed air blowing means 3. Further, a first exhaust port (corresponding to a regeneration air exhaust port) 14 is formed in the first north air passage 10a of the first layer 10, and humid air is sucked into the regeneration air blowing means 4 and exhausted through this. Is done.
In addition, a fourth exhaust port (corresponding to an adsorption air exhaust port) 43 is formed in the fourth north air passage 40a of the fourth layer 40, and the dry air that has passed through the device (outside air sent by the adsorption air blowing means 3) The same) is sucked into the regeneration air blowing means 4 and exhausted. The fourth south air passage 40b of the fourth layer 40 is provided with a fourth intake port (corresponding to a regenerative air intake port) 44, and outside air is sucked by the regenerative air blowing means 4, and the outside air is A heating means 5 for heating is installed.

(Operation)
Next, an example of the operation of the humidifier 100 will be described. FIGS. 3A and 3B are plan views showing the parts separately. FIG. 3A shows “damper position <A>” and FIG. 3B shows “damper position <B>”. .
The “damper position <A>” shown in FIG. 3 (a) is the same as FIG. 2, and the upper damper ventilation portion 50a of the upper airflow switching damper 50 is located in the northwest position, and the upper damper ventilation portion 50d is located in the southeast. On the other hand, the lower damper ventilation portion 60a of the lower air path switching damper 60 is stopped at the northeast position, and the lower damper ventilation portion 60d is stopped at the southwest position.

(Suction process at damper position <A>)
Accordingly, the outside air (hereinafter referred to as “adsorption inlet air”) W3 sucked from the first air inlet 13 flows from the first air inlet 13 to the first south air passage 10b (range of a semi-cylindrical cylinder) of the first layer 10. Inflow.
The adsorption inlet air W3 passes through the upper damper ventilation portion 50d (1/4 circle) of the upper air passage switching damper 50 and flows into the second east air passage 20b (a semi-cylindrical range) of the second layer 20. At this time, since the upper damper closing portion 50b of the upper air path switching damper 50 covers the southwestern range (1/4 circle) of the second west air path 20a of the second layer 20, the adsorption inlet air W3 becomes the second west air path. It does not flow into 20a.

Since the second east wind passage 20b, the east moisture adsorption means 2b, and the third east wind passage 30b are all semi-cylindrical and are in close contact with each other, the adsorption inlet air W3 flowing into the second east wind passage 20b. Passes through the east moisture adsorbing means 2b and flows into the third east wind passage 30b. At this time, the moisture contained in the adsorption inlet air W3 is adsorbed by the east moisture adsorption means 2b and becomes the dried adsorption outlet air W32b.
Further, the adsorption outlet air W32b passes through the lower damper ventilation portion 60a (1/4 circle) of the lower air path switching damper 60 and flows into the fourth north air path 40a (a semi-cylindrical range) of the fourth layer 40. At this time, since the lower damper closing portion 60b of the lower air path switching damper 60 covers the southeast area (1/4 circle) of the fourth south air path 40b of the fourth layer 40, the adsorption outlet air W32b is in the fourth south. It does not flow into the air passage 40b.
And the adsorption outlet air W32b which flowed into the 4th north wind path 40a passes the 4th exhaust port 43, is attracted | sucked by the adsorption air ventilation means 3, and is exhausted outside via this.

(Regeneration process at damper position <A>)
On the other hand, the outside air (hereinafter referred to as “regeneration inlet air”) W4 sucked into the fourth south air passage 40b from the fourth air inlet 44 of the fourth layer 40 is heated by the heating means 5 to be hot and low-humidity air W45. Then, it passes through the lower damper ventilation portion 60d (1/4 circle) of the lower air path switching damper 60 and flows into the third west air path 30a (the range of the semi-cylinder) of the third layer 30.
Since the third west air passage 30a, the west moisture adsorption means 2a, and the second west air passage 20a are all semi-cylindrical and are in close contact with each other, the high-temperature and low-humidity air W45 that has flowed into the third west air passage 30a. Passes through the west moisture adsorbing means 2a and flows into the second west air passage 20a. At this time, the moisture adsorbed by the west moisture adsorbing means 2a is desorbed (taken away to the air side), and the high-temperature and low-humidity air W45 becomes the high-humidity regeneration outlet air W452a.
Then, the regeneration outlet air W452a passes through the upper damper ventilation portion 50a of the upper air path switching damper 50 and flows into the first north air path 10a of the first layer 10, and further passes through the first exhaust port 14 to regenerate. The air is sucked into the air blowing means 4 and conveyed to the room through this to humidify the room.

(Suction process at damper position <B>)
Next, after a lapse of time to complete the adsorption process in the east moisture adsorption unit 2b and the regeneration process in the west moisture adsorption unit 2a, the "damper position <A>" to the "damper position <B>" (( b) See)).
At this time, as shown in FIG. 3B, the upper damper ventilation portion 50a of the upper airflow switching damper 50 stops at the northeast position, and the upper damper ventilation portion 50d stops at the southwest position, while the lower airflow passage. The lower damper vent 60a of the switching damper 60 is stopped at the northwest position, and the lower damper vent 60d is stopped at the southeast position.

Therefore, the suction inlet air W3 (same as the outside air) sucked into the first south air passage 10b from the first air inlet 13 passes through the upper damper ventilation portion 50d (1/4 circle) and passes through the second layer 20 2 flows into the west wind path 20a (the range of the semi-cylinder), and then passes through the west moisture adsorption means 2a and flows into the third west wind path 30a. At this time, the moisture contained in the adsorption inlet air W3 is adsorbed by the west moisture adsorption means 2a and becomes the dried adsorption outlet air W32a.
Further, the adsorption outlet air W32a passes through the lower damper ventilation portion 60a (1/4 circle), flows into the fourth north air passage 40a (a semi-cylindrical range) of the fourth layer 40, and passes through the fourth exhaust port 43. Then, the air is sucked into the adsorption air blowing means 3 and exhausted to the outside through this.

(Regeneration process at damper position <B>)
On the other hand, the outside air (hereinafter referred to as “regeneration inlet air”) W4 sucked into the fourth south air passage 40b from the fourth air inlet 44 of the fourth layer 40 is heated by the heating means 5 to be hot and low-humidity air W45. Then, it passes through the lower damper ventilation portion 60d (1/4 circle) and flows into the third east wind passage 30b (the range of the semi-cylinder) of the third layer 30.
The high-temperature and low-humidity air W45 that has flowed into the third east wind passage 30b passes through the east moisture adsorption means 2b and flows into the second east wind passage 20b. At this time, the moisture adsorbed on the east moisture adsorbing means 2b is desorbed, and the high-temperature and low-humidity air W45 becomes the regeneration outlet air W452b having a high humidity.
Then, the regeneration outlet air W452b passes through the upper damper ventilation portion 50a, flows into the first north air passage 10a of the first layer 10, passes through the first exhaust port 14, and is sucked into the regeneration air blowing means 4. Then, it is conveyed into the room via this to humidify the room.

(Continuous humidification)
As described above, at the damper position <A>, the regeneration outlet air W452a is obtained by the adsorption (collecting moisture) of the east moisture adsorbing means 2b and the desorption (releasing moisture) of the west moisture adsorbing means 2a. On the other hand, at the damper position <B>, the regeneration outlet air W452b is obtained by desorption (releases moisture) of the east moisture adsorption means 2b and adsorption (collects moisture) of the west moisture adsorption means 2a.
(A) Accordingly, the damper position <A> and the damper position <B> can be executed by simply rotating the upper air path switching damper 50 and the lower air path switching damper 60. Therefore, this is repeated alternately. By a simple operation of switching the air path, humidified air can be continuously supplied into the room (more precisely, the regeneration outlet air W452a and the regeneration outlet air W452b are alternately supplied).
(B) Since the wind direction in the west moisture adsorption means 2a and the wind direction in the east moisture adsorption means 2b are opposite, that is, the wind direction in the adsorption process and the wind direction in the regeneration process are "opposite flows", the thickness of the moisture adsorption means 2 is Even when the amount of moisture adsorbed (or desorbed) increases and a non-uniform distribution occurs in the thickness direction, moisture adsorption and regeneration can be performed efficiently.

(C) Since the optimum value for switching the air path differs depending on the type of adsorbent supported on the moisture adsorption means 2, for example, a material having a relatively high adsorption rate such as zeolite is short (about In the case of a material with a relatively low adsorption rate such as silica gel, it can be set to a long time (about 90 to 180 seconds), so that an optimum operation can be performed for an adsorbent having various characteristics. Become.
(D) Since the second air passage partition plate 21 and the third air passage partition plate 31 are in close contact with the moisture adsorption means 2, air leakage in the vicinity of the moisture adsorption means 2 can be minimized. In the conventional rotor type that rotates the moisture adsorbing means 2, the degree of sealing in the vicinity of the moisture adsorbing means 2 is not sufficient, and the air leakage from this portion is the largest.

(E) Since the rotating parts (upper air path switching damper 50 and lower air path switching damper 60) do not slide on the moisture adsorption means 2, the end surfaces of the upper air path switching damper 50 and the lower air path switching damper 60 are Even if materials having excellent flexibility such as urethane are added, they can be rotated with low torque, and air leakage in the vicinity of the upper air path switching damper 50 and in the vicinity of the lower air path switching damper is minimized. It becomes possible to suppress to.
(F) Further, the adsorption air passage through which the low-temperature air flows and the regeneration air passage through which the high-temperature humidified air are switched alternately, and the specific air passage is not cooled, so that it is difficult for condensation to occur. The conventional rotor system has a structure in which the adsorption air passage and the regeneration air passage are always fixed, and condensation is likely to occur on the regeneration air passage side of the boundary surface between the two air passages.

(Rotation of air path switching damper)
The rotation direction and the rotating means of the upper air path switching damper 50 and the lower air path switching damper 60 are not limited. For example, even if the rotation in the same direction is intermittently repeated at an angle of 90 °, both of the rotation directions and rotation means are 90 degrees. Rotation in one direction (clockwise) and rotation in the opposite direction (counterclockwise) at an angle of 90 ° may be alternately repeated intermittently, or each may rotate at an angle of 90 ° separately. May be executed.
In addition, the rotation mechanism (rotation drive mechanism) of the upper air path switching damper 50 and the lower air path switching damper 60 is not limited. For example, when both are in the same direction, the central axis is installed in the damper and the axis is Either a rotating mechanism or a mechanism that rotates by installing a gear or the like on the outer peripheral portion, the motor can be rotated by one, and the cost can be reduced.

(Structure of air path switching damper)
The present invention does not limit the structures of the upper air path switching damper 50 and the lower air path switching damper 60.
For example, as shown in FIG. 4A, in the upper air path switching damper 50, the upper damper closing plate 52 is disposed on the first layer 10 side of the upper damper partition plates 51, 51 (on the opposite side of the moisture adsorbing means 2). , 52 are installed, and the upper damper partition plates 51, 51 protrude toward the moisture adsorption means 2 side.
As a result, the upper damper partition plates 51 and 51 slide on the second air passage partition plate 21 and stop rotating, so that the second air passage partition plate 21 serves as a stopper and no rotation error occurs. Since the lower end surfaces of the damper partition plates 51 and 51 and the upper end surface of the second air passage partition plate 21 are in close contact with each other over a wider area, it is possible to prevent air leakage.
Further, since the upper damper closing plates 52 and 52 always rotate while sliding on the first air passage partition plate 11, the upper end surfaces of the upper damper closing plates 52 and 52 and the lower part of the first air passage partition plate 11 are rotated. Since the end surface is always in close contact with a wider area, air leakage can be prevented.

For example, as shown in FIG. 4B, in the upper air path switching damper 58, upper damper closing plates 52, 52 are installed on the moisture adsorbing means 2 side of the upper damper partition plates 51, 51. 51 and 51 protrude from the first layer 10 (on the opposite side of the moisture adsorption means 2).
As a result, the upper damper closing plates 52, 52 always slide and rotate on the second air passage partition plate 21, so that the lower end surface of the upper damper closing plates 52, 52 and the upper end surface of the second air passage partition plate 21 are However, since it always adheres in a wider area, it is possible to prevent air leakage.
In addition, since the upper damper partition plates 51 and 51 slide on the first air passage partition plate 11 and stop rotating, the first air passage partition plate 11 serves as a stopper and no rotation error occurs, and the upper damper. Since the upper end surfaces of the partition plates 51 and 51 and the lower end surface of the first air passage partition plate 11 are in close contact with each other over a wider area, it is possible to prevent air leakage.

Although the above shows that the upper damper partition plates 51 and 51 are plate-like members, the upper damper partition plates 51 and 51 are removed, and the upper portion made of a fan-like (1/4 yen) plate material. The damper partition plates 51 and 51 may be structured so as to be simply connected at the fan-shaped main part.
Also, the lower air path switching damper 60 can be configured in the same manner as the upper air path switching dampers 50 and 58.

(Layer thickness)
Further, the thicknesses of the first layer 10, the second layer 20, the third layer 30, and the fourth layer 40 (the same in mutual magnitude relationship) are not limited.
For example, the thickness of the first layer 10 in which the first intake port 13 and the first exhaust port 14 are installed may be increased (for example, thicker than the second layer 20). At this time, since the opening area of the first intake port 13 and the first exhaust port 14 can be increased, thereby reducing the air path pressure loss, the adsorbed air blowing means 3 and the regenerative air blowing means 4 are made smaller. be able to.
On the other hand, the thickness of the second layer 20 may be increased (for example, thicker than the first layer 10). At this time, since air easily flows through the entire moisture adsorbing means 2, the wind speed distribution is made uniform, and the adsorbent carried on the entire moisture adsorbing means 2 can be effectively used.
Note that the third layer 30 and the fourth layer 40 are the same as the first layer 10 and the second layer 20, and thus the description thereof is omitted.

(Arrangement of air blowing means)
In FIG. 1, the adsorbed air blowing means 3 is configured to suck dry air W32a and W32b from the fourth exhaust port 43, and the regeneration air blowing means 4 is configured to suck humid air W452a and W452b from the first exhaust port 14, that is, the blowing means is moisture. It is installed on the leeward side of the suction means 2. At this time, since the air path pressure loss is reduced, the adsorption air blowing means 3 and the regeneration air blowing means 4 can be reduced in size, but the present invention is not limited to this.
On the other hand, the blowing means may be installed on the windward side of the moisture adsorbing means 2 so that the adsorbed air blowing means 3 pushes the outside air into the first intake port 13 and the regenerative air blowing means 4 pushes the outside air into the fourth intake port 44, respectively. . At this time, there is an effect that the wind speed distribution in the moisture adsorbing means 2 is made uniform, and the adsorbent supported on the entire moisture adsorbing means 2 can be used effectively.

(Layer arrangement)
In the above description, the relative positions of the parts are described using “east, west, south, north, and up and down” for the sake of convenience. Therefore, the humidifying device 100 can be installed in any direction on the map, or installed in a moving body (vehicle, ship, aircraft, etc.). It can be installed horizontally or upside down.
When the fourth layer 40 is installed so as to be higher in the vertical direction than the moisture adsorption means 2, the heating means 5 is disposed in the uppermost layer, so that it is temporarily supported by the moisture adsorption means 2. Even if adsorbent powder falls, the possibility of reaching the heating means 5 is reduced, and the reliability of the apparatus can be improved.

As described above, the humidifying device 100 has an air path with high airtightness and less air leakage by a simple operation of switching between two rotary dampers (more precisely, the upper air path switching damper 50 and the lower air path switching damper 60). And a humidifying device 100 that continuously supplies humidified air can be obtained.
At this time, since the adsorption process and the regeneration process in the moisture adsorbing means 2 carrying the adsorbent are opposite flows, adsorption and regeneration can be performed efficiently, and the highly efficient humidifier 100 can be obtained.
In addition, since the adsorption air path and the regeneration air path are alternately switched and the specific air path is not cooled, there is also an effect that it is difficult for condensation to occur in the humidifier 100.

(Diversion to drying equipment)
Although the present invention has been described as the humidifier 100 focusing on the use of the regeneration outlet air W452a and W452b as humidified air, the adsorption outlet air W32a and 32b as dry air can also be obtained continuously. Therefore, the humidifying device 100 can be called a drying device when paying attention to the latter.

In the following drawings, the same reference numerals are given to the same or corresponding parts as in the related form 1 (FIGS. 1 and 2), and a part of the description is omitted.

(Wind path)
In FIG. 5, the humidifier 200 includes an upper air path switching damper 60 (see FIG. 4C), and the second layer 20 is installed to be rotatable about the axis. A second air inlet 23 is formed in the second east air passage 20b of the second layer 20, and a second air outlet 24 is formed in the second west air passage 20a.
Further, an upper damper air inlet 53 is formed in the southwest and southeast areas at the position of the upper airway switching damper 60 in the vertical direction of the cylindrical body 1, and an upper damper air outlet 54 is formed in the northwest and northeast areas. ing. On the other hand, the upper damper side plates 53 and 53 of the upper air path switching damper 60 are hermetically slid on the inner surface of the cylindrical body 1 so that the upper damper inlet or the lower damper inlet can be closed. It has become.

  Therefore, when the upper damper closing portion 50b and the upper damper closing portion 50c of the upper air path switching damper 50 are stopped at the northeast and southwest positions, the upper damper side plate 53 located at the northeast serves as the upper damper exhaust port. The upper damper vent 50a located in the northwest and the upper damper exhaust port communicate with each other, and similarly, the upper damper side plate 53 located in the southwest block the upper damper intake port, and the upper damper located in the southeast.

(Suction at damper position <A>)
Next, an example of the operation will be described with reference to FIG. FIG. 6 is a plan view of each component shown in FIG. 5 and is based on FIG. 3 (related form 1), and therefore, description of common contents is omitted.
The damper position <A> shown in FIG. 6A is the same as FIG. At the damper position <A>, the outside air (adsorption inlet air) W3 sent out by the adsorption air blowing means 3 (not shown) passes through the first intake port 13 of the first layer 10 and the first south air passage 10b. Then, the air passes through the upper damper ventilation portion 50d of the upper wind path switching damper 50 and flows into the second east wind path 20b. The outside air W3 passes through the upper damper inlet 53 located in the southeast of the cylindrical body 1 and flows into the upper wind path switching damper ventilation portion 50d, and then flows into the second east wind path 20b. Further, the outside air W3 passes through the second air inlet 23 of the second layer 20 and directly flows into the second east wind passage 20b.

Into the third east wind passage 30b. Thereafter, the air passes through the lower damper ventilation portion 60a (northeast) of the lower air passage switching damper 60 and flows into the fourth north air passage 40a of the fourth layer 40. The air is exhausted outside the apparatus (for example, outdoors, etc.).

(Regeneration at damper position <A>)
On the other hand, the outside air sent out by the regeneration air blowing means 4 (not shown) is the fourth inlet of the fourth layer 40 from the fourth intake port 44 as the regeneration inlet air W4 as in the related form 1 (see FIG. 3). It flows into the south wind path 40b, is heated by the heating means 5, and becomes high-temperature and low-humidity air W45. Then, after passing through the lower damper ventilation portion 60d (southwest) of the lower air path switching damper 60 and flowing into the third west air path 30a of the third layer 30, it passes through the west moisture adsorbing means 2a and becomes humidified air W452a. And flows into the second west air passage 20a of the second layer 20.
Then, the humidified air W452a passes through the second exhaust port 24 of the second layer 20, and passes through the upper damper vent 50a of the upper airflow switching damper 50 and the upper damper intake port located in the northwest of the cylindrical body 1. Further, the air passes through the first exhaust port 14 of the first layer 10 and is conveyed as regeneration outlet air W452a (same as the humidified air W452a) outside the apparatus (for example, indoors) to humidify the indoors.

(Suction at damper position <B>)
Next, at the damper position <A>, after a time has passed to complete the adsorption process in the east moisture adsorption means 2b and the regeneration process in the west moisture adsorption means 2a, as shown in FIG. Switch to position <B>.
That is, the upper airflow switching damper 50 is rotated by an angle of 90 ° to stop the upper damper vent 50a and the upper damper vent 50d at the positions of the northeast and southwest respectively, and the first layer 1 formed in the first layer 1 The first intake port 13 and the first exhaust port 14, the second intake port 23 and the second exhaust port 24 formed in the second layer 20, and the lower air path switching damper 60 are rotated.
At this time, the moisture adsorption means 2, the first air path partition plate 11 of the first layer 10, and the second air path partition plate 21 of the second layer 20 do not rotate.

Therefore, at the damper position <B>, the outside air sent out by the adsorption air blowing means 3 (not shown) (same as the adsorption inlet air W3) passes through the first intake port 13 of the first layer 10 to the first. The air flows into the south air passage 10b, passes through the upper damper ventilation portion 50c of the upper air passage switching damper 50, and flows into the second west air passage 20a. The outside air W3 passes through the upper damper inlet 53 located in the southwest of the cylindrical body 1 and flows into the upper airflow switching damper vent 50c, and then flows into the second west airflow 20a. Further, the outside air W3 passes through the second air inlet 23 of the second layer 20 and directly flows into the second west air passage 20a.
Then, the adsorption inlet air W3 collected in the second west air passage 20a passes through the west moisture adsorption means 2a to become dry air W32a and flows into the third west air passage 30a of the third layer 30. Thereafter, the air passes through the lower damper ventilation portion 60a (northwest) of the lower airflow path switching damper 60 and flows into the fourth north airflow path 40a of the fourth layer 40, and further, the adsorption outlet air W32a (dry air) from the fourth exhaust port 43. It is exhausted outside the apparatus (for example, outdoor etc.) as the same as W32a.

(Regeneration at damper position <B>)
On the other hand, the outside air sent out by the regeneration air blowing means 4 (not shown) flows into the fourth south air passage 40b of the fourth layer 40 from the fourth intake port 44 as the regeneration inlet air W4 and rises by the heating means 5. It is heated and becomes high temperature and low humidity air W45. Then, after passing through the lower damper ventilation portion 60d (southeast) of the lower air path switching damper 60 and flowing into the third east air path 30b of the third layer 30, it passes through the east moisture adsorbing means 2b and becomes humidified air W452b. And flows into the second east wind passage 20b of the second layer 20. The humidified air W452b that has flowed into the second east wind passage 20b passes through the upper damper ventilation portion 50a and flows into the first north wind passage 10a.
Then, the humidified air W452b passes through the second exhaust port 24 of the second layer 20, passes through the upper damper vent 50a of the upper airflow switching damper 50 and the upper damper intake port (illustrated in the northeast of the cylindrical body 1). ) And further passes through the first exhaust port 14 of the first layer 10 and is transported outside the apparatus (for example, indoors) as regeneration outlet air W452b (same as the humidified air W452b) Humidify etc.

Since the switching damper 50 is rotatable, and the upper damper vents 50a and 50d can be communicated to the outside of the apparatus or can be disconnected from the outside of the apparatus, the air path for intake air and the air path for exhaust gas are expanded, and the wind The road pressure loss is small, the adsorption air blowing means 3 and the regeneration air blowing means 4 can be reduced in size, the wind speed distribution in the moisture adsorption means 2 is made uniform, and the adsorbent supported on the entire moisture adsorption means 2 is effective. There is an effect that can be used. In addition, since the structure except the above is the same as the humidification apparatus 100 (related form 1) including a variation, the effect similar to the humidification apparatus 100 is acquired.
In the humidifier 200, the wind flow may be parallel flow according to the humidifier 100 (related form 1). Further, the rotation of the upper air path switching damper 50 and the lower air path switching damper 60 is an intermittent one in which the rotation direction is alternately changed (forward or reverse) even if the rotation is intermittent in one direction. May be. Furthermore, the east, west, north, north, and up and down directions are for convenience of explanation, and do not limit the installation direction of the apparatus.

[Related Mode 3: Humidification Device 3]
FIG. 7: is a fragmentary top view which shows typically the operation | movement explaining the humidification apparatus which concerns on the form 3 which concerns on this invention.
In FIG. 7, the humidifier according to the third embodiment related to the present invention (hereinafter referred to as “humidifier 300”) is installed on the outer periphery of the first layer 10, the upper air path switching damper 50, and the second layer 20. The adsorbed air intake port and the regeneration air exhaust port (which will be described in detail below) rotate 180 °, the upper air path switching damper 50 does not rotate, and the lower air path switching damper 60 rotates 90 °.
For example, the upper wind path switching damper 50 (same as the upper damper partition plate 51) is fixedly installed at the upper end surface of the first air path partition plate 11 and the lower end surface thereof is fixed at the second air path partition plate 21. . And since the structure except this is the same as the humidification apparatus 200, the same code | symbol is attached | subjected to the part which is the same as FIG. 5 and FIG. 6 (related form 2), or an equivalent part, and a one part description is abbreviate | omitted.
The damper position <A> shown in (a) of FIG. 7 is the same as (a) of FIG.

(Suction at damper position <B>)
In the damper position <B> shown in FIG. 7B, the outside air (adsorption inlet air) W3 sucked by the adsorption air blowing means 3 (not shown) is the first of the first layer 10 located in the northwest. After flowing into the first north wind passage 10a located north via the intake port 13, it passes through the upper damper intake port 53 located in the southwest of the cylindrical body 1 and passes through the upper portion of the upper air path switching damper 50. It flows into the damper ventilation part 50a, and flows into the 2nd west wind path 20a located in the west side. Further, the outside air W3 passes through the upper damper air inlet 53 of the upper airflow switching damper 50 and flows into the upper damper ventilation portion 50a, and then flows into the second west airway 20a. Furthermore, the outside air W3 passes through the second air inlet 23 of the second layer 20 located in the northwest, and directly flows into the second west air passage 20a.

(Regeneration at damper position <B>)
At the damper position <B> shown in FIG. 7B, the outside air (regeneration inlet air) W4 sucked by the regeneration air blowing means 4 (not shown) is absorbed by the fourth layer 40, the third layer 30, and the east moisture. Since the regeneration procedure and the flow of the humidified air W452b after passing through the means 2b are the same as in FIG. 6B, the description thereof is omitted.
The high-temperature and high-humidity air W452b flowing into the second east wind passage 20b of the second layer 20 and the second exhaust port 24 (located in the southeast) of the second layer 20 are passed over the upper air passage switching damper 50. The damper vent 50a (located in the southeast) and the upper damper exhaust port 54 located in the southeast of the cylindrical body 1 pass through, and further, the first exhaust port 14 (located in the southeast of the first layer 10). ) And is transported as regeneration outlet air W452b (same as humidified air W452b) to the outside of the apparatus (for example, indoors) sucked by the regeneration air blowing means 4, and humidifies the interior of the room.

Therefore, in the humidifying device 300, the first layer 10, the upper air path switching damper 50, and the second layer 20 are fixed to each other, so that it is possible to consolidate the rotating means of the integrated object into one unit. However, the present invention is not limited to this. For example, the first layer 10, the upper air path switching damper 50, and the second layer 20 may be rotated by separate rotating means.
In addition, in the humidifier 200 and the humidifier 300, the wind flow may be paralleled according to the humidifier 100 (related form 1). Further, the rotation of the upper air path switching damper 50 and the lower air path switching damper 60 is an intermittent one in which the rotation direction is alternately changed (forward or reverse) even if the rotation is intermittent in one direction. May be. Furthermore, the east, west, north, north, and up and down directions are for convenience of explanation, and do not limit the installation direction of the apparatus.

[Embodiment 1: Air conditioner 1]
FIG. 8 illustrates the air conditioner according to Embodiment 1 of the present invention, and is a perspective view schematically showing a schematic configuration of the outdoor unit.
In FIG. 8, the air conditioner 400 includes an outdoor unit 400a, an indoor unit (not shown), and an indoor / outdoor connection duct 430 that connects the two.
In the outdoor unit 400 a, the humidification unit 100 (related form 1) arranged at the upper part and the refrigeration unit 420 arranged at the lower part of the casing 410 are integrated into the casing 410.
As is well known, the refrigeration unit 420 includes a compressor 421, an outdoor unit heat exchanger 422, an outdoor unit blower 423, an expansion valve 424, and a refrigerant pipe (not shown) that connects these to flow a refrigerant. A part of the piping is connected to a heat exchanger of an indoor unit (not shown) to form a heat pump cycle.

The housing 410 has an outdoor exhaust port 413 communicating with the adsorbed air blowing means 3 (which communicates with the fourth exhaust port 43 of the humidifying unit 100) and a regenerative air blowing means 4 (the first exhaust port of the humidifying unit 100). And an indoor connection port 414 communicating with the outdoor exhaust port 413 is open to the outside.
The indoor / outdoor connection duct 430 has a double tube structure including an inner tube 431 and an outer tube 432, and the outer tube 432 is shorter than the inner tube 431, and the outer tube 432 penetrates the inner tube 431. Presents. An end cap 435 for sealing the space between the inner tube 431 and the outer tube 432 is installed at both ends of the outer tube 432, and a small hole 436 is provided in one or both of the end caps 435.

  In addition, a wall hole 901 is formed in the outer wall 900 of a building where an indoor unit (not shown) is installed. The outdoor unit side of the inner pipe 431 is in close contact with the indoor connection port 414, and the indoor unit side of the inner pipe 431 passes through the wall hole 901 and is connected to an indoor unit (not shown) disposed indoors. Yes. At this time, the outer pipe 432 is installed only in the outdoor portion in contact with the outside air of the indoor / outdoor connection duct 430. Note that description of the humidifying unit 100 (related form 1) is omitted.

(Operation)
Next, an example of the operation will be described. In addition, description is abbreviate | omitted about operation | movement of the humidification unit 100 (related form 1) itself.
When the refrigeration unit 420 performs the heat pump cycle and performs the heating operation, the upper air path switching damper 50 and the lower air path switching damper 60 are repeatedly switched so that the damper position <A> and the damper position <B> are obtained. By (intermittently rotating), the adsorption outlet air W32a and 32b (dry air is sucked by the adsorption air blowing means 3 and passes through the moisture adsorption means 2), and the regeneration outlet air is high-temperature and high-humidity air W452a and W452b (suctioned by the regeneration air blowing means 4 and heated by the heating means 5 and then passed through the moisture adsorption means 2) are continuously discharged from the humidification unit 100.

At this time, since the humidification unit 100 is installed integrally with the upper part of the outdoor unit 400a, the outdoor exhaust port 413 is close to the refrigeration unit 420, and the adsorption outlet air W32a, 32b is the air suction of the outdoor unit heat exchanger 422. It will be exhausted near the mouth.
On the other hand, regeneration outlet air W452a and W452b, which are high-temperature and high-humidity air, pass through the inner pipe 431 of the indoor / outdoor connection duct 430 that connects the room and the outdoors, and are conveyed into the room by the regeneration air blowing means 4. Therefore, the high temperature air discharged from the indoor unit to the room is humidified by the regeneration outlet air W452a and W452b, and the room is heated and humidified.

As described above, the outdoor unit 400a is formed by integrally installing the humidifying unit 100 on the upper part of the refrigeration unit 420. Therefore, without securing a floor space for newly installing the humidifying unit 100, An air conditioner having a humidifying function that can be installed in a relatively narrow space can be obtained.
Further, simultaneously with the heating operation of the heat pump cycle, humidified air (regeneration outlet air W452a, W452b) can be continuously supplied to the room, so that an effect of preventing drying during heating can be obtained.
Also, the adsorption outlet air W32a and 32b, which is dry air and has a temperature slightly higher than the outside air due to adsorption heat, is sucked into the outdoor unit heat exchanger 422 as an evaporator during the heating operation of the heat pump cycle. Moreover, the effect of suppressing the frost formation in the outdoor unit heat exchanger 422 and improving the heating operation efficiency can be expected.

(Thermal characteristics of indoor and outdoor connecting ducts)
FIG. 9 is an analysis diagram illustrating the thermal characteristics of the indoor / outdoor connection duct in the air conditioner according to Embodiment 1 of the present invention.
In the indoor / outdoor connection duct 430, a heat insulating material such as polyethylene or glass wool is generally installed in a space sealed by the inner tube 431, the outer tube 432, and the end cap 435. It is desirable to fill with low static air (thermal conductivity = about 0.025 W / mK).

FIG. 9 is a result of actual measurement (from the duct entrance to 5 m) and analysis (from the duct entrance to 10 m) of the temperature drop in various ducts. As conditions, the ambient temperature / humidity is 7 ° C. / Assuming a humidification amount of 600 cc / h, the air volume is set to 0.35 m ³ / min, and the temperature and humidity are set to 61 ° C./22% RH. In the figure,
T37 is not a double-pipe structure, the measured value of the temperature drop in a single pipe,
T38 is the same analysis value,
T39 is a measured value of temperature drop in a double pipe in which a heat insulating material is installed in the space,
T40 is the same analysis value,
T41 is the measured value of the temperature drop in the double pipe in which still air is sealed in the space,
T42 is the same analysis value,
T43 is the dew point temperature of the duct inlet air.

Each duct has an inner diameter of 25 mm and an outer diameter of 35 mm. Double-pipe ducts use polypropylene as the reinforcing material and polyethylene as the outer winding, and a heat insulating material or static air is sealed inside. Polyethylene is used except for polypropylene.
From FIG. 9, in the case of a single pipe (analysis value T38), the dew point temperature drops to T43 at about 5 m from the duct inlet and dew condensation occurs inside, whereas a double pipe (analysis is installed) In the value T40), condensation occurs at about 9 m, and in the double pipe (analysis value T42) in which still air is sealed, no condensation occurs even at a position of 10 m.

(Still air filling)
In a separate type general air conditioner for home use, the distance between the outdoor unit and the indoor unit is usually about 4 to 5 m. However, depending on the installation position of the outdoor unit, the distance between the indoor unit and the external connection pipe length in the chargeless LEV model Since the standard is 10 m, in such a case, even a double pipe provided with a heat insulating material will cause condensation.
Therefore, the indoor / outdoor connecting duct has a double-pipe structure, and the space sealed by the inner tube 431, the outer tube 432, and the end cap 435 is filled with static air, thereby providing higher heat insulating performance than installing a heat insulating material. It can be ensured, and condensation in the inner pipe 431 can be suppressed. Accordingly, it is possible to avoid hygienic problems such as a strange odor generated from the dew condensation water being transported indoors along with the regeneration outlet air W452a and W452b, and generation of abnormal noise due to contact between the dew condensation water and the regeneration outlet air W452a and W452b. be able to. Or since the same heat insulation performance as the case where a heat insulating material is installed can be secured with a thinner still air layer, the diameter of the outer tube 432 can be reduced, and a more compact heat insulating double tube can be obtained. it can.

(Through the hole in the wall)
Further, the inner diameter of the wall hole 901 formed in the outer wall 900 of the building where the indoor unit is installed corresponds to a general home air conditioner, and is about 60 to 70 mm. Together with the drain hose, the inner pipe 431 of the indoor / outdoor connection duct 430 is penetrated.
That is, in order to convey the regeneration outlet air W452a and W452b, which are humidified air, into the room, the inner diameter of the inner tube 431 needs to ensure a certain size (about 30 mm) due to problems such as duct noise. Since it is difficult to penetrate the whole indoor / outdoor connection duct 430 including the outer pipe 432 surrounding the inner pipe 431 in consideration of workability, only the inner pipe 431 passes through the wall hole 901.
That is, as shown in FIG. 8, the outer tube 432 may be installed only outside the room, and only the portion in contact with the outside air where the temperature lowers may have a double tube structure. Thereby, not only the dew condensation inside the inner pipe 431 can be suppressed, but also the workability of the indoor / outdoor connection duct 430 can be improved. In addition, this invention is not limited to the said structure, The outer pipe | tube 432 of the indoor / outdoor connection duct 320 may penetrate the wall hole 901, and the double pipe structure over the whole may be sufficient.

  In addition, in the double pipe structure as described above, when static air is filled in the space sealed by the inner pipe 431, the outer pipe 432, and the end cap 435, condensation does not occur inside the inner pipe 431. When the temperature of the still air is higher than the outside air, there is a possibility that the still air is condensed by being cooled by the outside air. In such a case, as shown in FIG. 8, by installing small holes 436 at both ends of the end cap 435 or at either end, the dew condensation water staying between the inner tube 431 and the outer tube 432 is removed. It can be discharged and hygienic problems such as off-flavors can be avoided.

(Material for indoor / outdoor connection ducts)
Further, the material of the inner tube 431, the outer tube 432, and the end cap 435 is a material having a low thermal conductivity as much as possible in the same manner as described above in which high heat insulation performance can be obtained by sealing still air having a low thermal conductivity. For example, a resin is desirable. Thereby, since the heat insulation effect is obtained not only in the heat insulation layer such as still air sealed inside, but also in the inner pipe 431 and the outer pipe 432, dew condensation can be further suppressed.
In addition, it is desirable that reinforcing wires (for example, spiral wires) such as polypropylene are installed in the inner tube 431 and the outer tube 432 so that the reinforcing wires have mountain-like structures. That is, since the indoor / outdoor connection duct 430 always has a bent portion as shown in FIG. 8, if the bellows-like structure is made flexible, the construction is facilitated and the workability is improved. It can also contribute to space saving during storage and transportation. The present invention is not limited to this. For example, a flexible smooth tube (without bellows), a bent tube (elbow etc.) and a straight tube are combined. Also good.

(Removal of air blowing means)
Further, in FIG. 8, the adsorption air blowing means 3 is installed exclusively for exhausting the adsorption outlet air W32a and 32b (same for intake of the adsorption inlet air W3), but this is removed and the refrigeration unit 420 is replaced. You may make it attract | suck the adsorption | suction exit air W32a and W32b with the outdoor unit air blower 423 which comprises. That is, since the humidification unit 100 is integrally installed on the upper part of the refrigeration unit 420, the adsorbed air blowing means 3 is removed, and the fourth exhaust port 43 of the fourth layer 40 is formed on the lower surface of the fourth north air passage 40a. You may form and may make the 4th north wind path 40a connect with the wind path which the outdoor unit air blower 423 forms. Alternatively, a guide pipe may be installed at the fourth exhaust port 43 of the fourth layer 40 so that the adsorption outlet air W32a and W32b are guided to the wind of the outdoor unit heat exchanger 422.
In this case, since only the regenerative air blowing means 4 is required for the blower installed in the humidification unit 100, the number of blowers can be reduced, and the manufacturing cost and operation cost can be reduced.

(Other forms)
The air conditioner 400 is not limited to the one equipped with the humidifying unit 100 (related form 1), but is equipped with the humidifying units 200 and 300 (related forms 2 and 3) instead of the humidifying unit 100. May be.
Furthermore, the “upper part” in the outdoor unit 400 a is not limited. For example, when the outdoor unit 400 a is installed on the ceiling of a veranda, the humidification unit 100 is installed integrally below the refrigeration unit 420. When the outdoor unit 400a is installed on a wall surface of a building or the like, the humidifying unit 100 includes a unit that is integrally installed on the side of the refrigeration unit 420.

(Characteristics of air conditioner)
(A) As described above, the air conditioner 400 is installed in the outdoor unit 400a of the air conditioner 400 so as to be integrated in the outdoor unit 400a and is humidified simultaneously with the heating operation of the heat pump cycle. It can be said that it is an air conditioner having a humidifier that can prevent drying during heating.
(B) At this time, the air (adsorption outlet air W32a, 32b) that has been adsorbed and dehumidified by the moisture adsorbing means 2 and slightly raised in temperature by the heat of adsorption is sucked into the outdoor unit heat exchanger 422 that is an evaporator. Therefore, the effect of suppressing the frost formation in the outdoor unit heat exchanger 422 and improving the heating operation efficiency can be expected.

(C) Also, the indoor / outdoor connection duct 430 has a double-pipe structure, and by sealing the static air between the inner pipe 431 and the outer pipe 432, a higher heat insulating performance can be obtained than when a heat insulating material is installed. Condensation inside the tube 431 can be suppressed, or a more compact heat insulating double tube can be obtained.
(D) Furthermore, by providing a small hole 436 in the end cap 435 of the outer pipe 432, even if condensation occurs inside the outer pipe 432, condensed water can be discharged, avoiding sanitary problems. It becomes possible to do.
(E) Furthermore, by making the double pipe into a bellows-like structure and making it flexible, it not only facilitates construction and improves workability, but also contributes to space saving during storage and transportation. .

(Give drying function)
As described above, the air conditioner 400 having a humidifying function has been described by paying attention to the use of the regeneration outlet air W452a and W452b as humidified air, but the adsorption outlet air W32a and 32b as dry air can also be obtained continuously. Therefore, if a new indoor / outdoor connection duct for conveying the suction outlet air W32a, 32b sent out by the suction air blowing means 3 into the room is provided, it can be used for indoor drying. At this time, if a new indoor / outdoor connection duct is communicated with the indoor / outdoor connection duct 430 and a switching valve is installed, indoor humidification and drying can be used properly.
The term “room” is not limited to the room of a building in which humans live, but includes the inside of a warehouse, a plastic house, a stable, or the inside of a device housing.

[Embodiment 2: Air conditioner 2]
FIG. 10 illustrates an air conditioner according to Embodiment 2 of the present invention, and is a perspective view schematically showing a schematic configuration of an outdoor unit.
In FIG. 10, an air conditioner 500 has an indoor / outdoor connection duct 530 provided with a regeneration outlet air bypass pipe 544 instead of the indoor / outdoor connection duct 430 of the air conditioner 400 (Embodiment 1). . And since the structure except this is the same as the air conditioner 400, the same code | symbol is attached | subjected to the part which is the same as FIG. 8 (Embodiment 1), or an equivalent part, and one part description is abbreviate | omitted.
That is, one end of the regeneration outlet air bypass pipe 544 communicates with the gap between the inner pipe 431 and the outer pipe 432 of the indoor / outdoor connection duct 530, and the other end communicates with the exit side of the regeneration air blowing means 4.

(Operation)
Next, an example of the operation will be described. Regarding the operation, description of the same parts as those of the air conditioner 400 (Embodiment 1) will be omitted.
When the heat pump cycle is performing heating operation, the high-temperature and high-humidity regeneration outlet air W452a and W452b are sent out by the regeneration air blowing means and continuously conveyed into the room through the inner pipe 431 of the indoor / outdoor connection duct 530. At the same time as heating and humidifying the room, a part thereof is supplied to the space sealed by the inner pipe 431, the outer pipe 432 and the end cap 435 through the regeneration outlet air bypass pipe 544.
Therefore, the amount of humidified air of high temperature and high humidity supplied to the room (humidification amount) is reduced, but the inside of the outer tube 432 is kept at a high temperature, and the effect of suppressing condensation inside the inner tube 431 is suppressed. Can be expected.

(Thermal characteristics of indoor and outdoor connecting ducts)
FIG. 11 is an analysis diagram illustrating the thermal characteristics of the indoor / outdoor connection duct in the air conditioner according to Embodiment 2 of the present invention. In FIG. 11, it is the analysis result (from duct entrance to 10m) of the temperature fall in various double pipe ducts, and as the analysis conditions, the ambient temperature and humidity are assumed to be standard heating conditions as in the first embodiment. Assuming a humidification amount of 600 cc / h for the duct inlet air at 7 ° C./87% RH, the air volume is 0.35 m 3 / min in total for the inner pipe 431 and the outer pipe 432, and the temperature and humidity is 61 ° C./22% RH It is set.
The temperature drop analysis value T42 when the still air is sealed inside the outer pipe 432 and the dew point temperature T43 of the duct inlet air are the same as in the first embodiment. In the figure,
T45 is an analysis value of a temperature drop in the inner pipe 431 when the regeneration outlet air W452a and W452b are supplied to the outer pipe 432 side at 0.05 m3 / min,
T46 is an analysis value of the temperature drop in the outer pipe 432,
T47 is an analysis value of a temperature drop in the inner pipe 431 when the regeneration outlet air W452a and W452b are supplied to the outer pipe 432 side by 0.07 m 3 / min,
T 48 is an analysis value of the temperature drop in the outer tube 432.

The specifications of the double pipe duct are the same as those in the first embodiment. At this time, the outer pipe 432 side of the double pipe is in contact with the outside air in the same manner as the single pipe, and therefore, the dew point temperature T43 is lowered before 10 m from the inlet. In particular, T46 with a small air volume has a longer contact time with the outside air, and therefore, a tendency of dew condensation earlier can be seen.
On the other hand, with respect to the inner pipe 431 side, T45 and T47 supplied with high-temperature regeneration outlet air W452a and W452b to the outer pipe 432 side have a temperature of about 3 to 4 m from the inlet as compared with T42 in which still air is sealed. It is shown that the decrease is suppressed and the temperature at the 10 m position is also increased.

Therefore, the indoor / outdoor connection duct has a double-pipe structure, and a part of the high-temperature regeneration outlet air W452a and W452b is supplied to the space sealed by the inner pipe 431, the outer pipe 432, and the end cap 435, thereby insulating the heat. Higher heat insulation performance can be ensured than filling with material and still air. Therefore, since dew condensation in the inner pipe 431 can be suppressed, hygienic problems such as a strange odor generated from the dew condensation water being transported indoors along with the regeneration outlet air W452a and W452b, and the dew condensation water and the regeneration outlet air W452a. , Generation of abnormal noise due to contact with W452b can be avoided.
Or since the same heat insulation performance as the case where a heat insulating material is installed can be ensured by a thinner still air layer, the diameter of the outer tube 432 can be reduced, and a more compact heat insulating double tube can be obtained. it can.

Here, in the result of FIG. 11, when more regeneration outlet air W452a and W452b are supplied to the outer pipe 432 side, the temperature drop T47 in the inner pipe 431 is suppressed. Therefore, it is desirable to change the air volume balance of the regeneration outlet air W452a and W452b supplied to the inner tube 431 side and the outer tube 432 side according to conditions.
For example, when a larger amount of humidification is required in the room, the amount of air supplied to the inner tube 431 is increased, and when there is a high possibility of dew condensation such as when the temperature of the outside air is low, the outer tube 432 By increasing the amount of air supplied to the side, it is possible to supply the necessary amount of humidification indoors while suppressing condensation in the inner pipe 431.

Further, as shown in FIG. 11, by supplying a part of the high-temperature regeneration outlet air W452a, W452b to the space sealed by the inner tube 431, the outer tube 432, and the end cap 435, the inner tube 431 is provided. Condensation in the interior of the tube can be suppressed, but there is a high possibility that condensation will occur on the outer tube 432 side exposed to the outside air (temperature decreases) as in the single tube structure. In such a case, as shown in FIG. 10, the condensate accumulated between the inner pipe 431 and the outer pipe 432 is discharged by installing small holes 436 at both ends of the end cap 435 or at one end thereof. It is possible to avoid sanitary problems such as off-flavors.
The regeneration outlet air W452a and W452b flowing into the gap passes through the small hole 436 and is diffused into the outside air. However, even if a hole for the diffusion is provided at a desired position of the outer pipe 432, Good.

(A) As described above, in the air conditioner 500, the indoor / outdoor connection duct 530 has a double pipe structure, and a part of the high-temperature regeneration outlet air W452a, W452b is supplied between the inner pipe 431 and the outer pipe 432. By doing so, not only the effect described for the air conditioner 400 (Embodiment 1) for sealing still air is obtained, but also a heat retention effect (heat insulation performance) higher than that for sealing still air is obtained. Condensation inside the tube 431 can be suppressed. Alternatively, a more compact insulated double tube can be obtained.
(B) By providing a small hole in the end cap of the outer tube, the dew condensation water generated inside the outer tube can be discharged, and it becomes possible to avoid sanitary problems.
(C) Also, the inner pipe 431 is changed by changing the air volume balance of the regeneration outlet air W452a and W452b supplied to the inner pipe 431 side and the outer pipe 432 side according to the required humidification amount and the outside air condition in the room. It is possible to supply the necessary amount of humidification indoors while suppressing condensation in the room.
