[Description of Embodiment]
(Knowledge Forming Basis of the Present Disclosure)
-
At the time when the inventors conceived the present disclosure, a humidity controlling device included an air supply flow path through which air flowed from outside air to an indoor space and an air discharge flow path through which air was discharged from the indoor space to the outside air, heat exchange was performed between an air supply side and an air discharge side by sensible heat exchange using a heat storage amount, and humidity control was thereafter performed by a single disc-type humidity controlling material which caused air to pass through a coil and rotated in the same direction in flow paths on the air supply side and on the air discharge side.
-
However, the inventors have found a problem that when air passes through insides of the air supply flow path and the air discharge flow path and heat exchange is performed between sensible heat of both of the air supply flow path and the air discharge flow path via a total heat exchanger, supplied air caused to flow as laminar flow by the total heat exchanger is cooled by a cooling coil, and discharged air caused to flow as laminar flow heats the disc-type humidity controlling material via a heating coil, but because of its uniform heating temperature, release of humidity from the disc-type humidity controlling material is slow, and a humidity controlling amount lowers. In order to solve this problem, the inventors have reached a configuration of a subject of the present disclosure.
-
Accordingly, the present disclosure provides a humidity controlling device that quickly performs release of humidity from humidity controlling means, thereby achieves a rapid start-up, and can improve performance for a humidity controlling amount.
-
An embodiment will hereinafter be described in detail with reference to drawings. However, unnecessarily detailed descriptions may be skipped. For example, detailed descriptions about items which are already well known or duplicate descriptions about substantially the same configurations may be skipped. This is for avoiding a situation where the following descriptions become unnecessarily redundant and is for easy understanding for persons skilled in the art.
-
Note that the attached drawings and the following descriptions are provided for persons skilled in the art to sufficiently understand the present disclosure but are not intended to limit a subject described in claims by those.
(First Embodiment)
-
In the following, a first embodiment will be described by using the drawings.
[1-1. Configuration]
[1-1-1. Configuration of Humidity Controlling Device]
-
Fig. 1 is an outline cross-sectional view of a humidity controlling device 1 in the first embodiment. In the following description, descriptions about directions such as front, rear, left, right, up, and down will be used while the humidity controlling device 1 illustrated in Fig. 1 is set as a reference.
-
The humidity controlling device 1 has a housing 10 in a general rectangular cuboid shape. In an internal portion of the housing 10, an air supply flow path 11 through which air introduced from an outdoor space and supplied to an indoor space as an air-conditioning target space, so-called supplied air, flows and an air discharge flow path 12 through which air introduced from the indoor space and discharged to an outside, so-called discharged air, flows are provided.
-
An outside air supply opening 13 is provided at an upstream end of the air supply flow path 11. An indoor air supply opening 14 is provided at a downstream end of the air supply flow path 11.
-
An indoor air return opening 15 is provided at an upstream end of the air discharge flow path 12. An outside air discharge opening 16 is provided at a downstream end of the air discharge flow path 12.
-
In the air supply flow path 11, an air supply fan 17 as supplied air conveying means is arranged. The air supply fan 17 is actuated, air thereby flows through the air supply flow path 11, and air is supplied to the indoor space.
-
In the air discharge flow path 12, an air discharge fan 18 as discharged air conveying means is arranged. The air discharge fan 18 is actuated, air thereby flows through the air discharge flow path 12, and air is discharged from the indoor space.
-
On the air supply flow path 11 and on the air discharge flow path 12, a total heat exchanger 20 as total heat exchanging means is arranged.
-
The total heat exchanger 20 of the present embodiment is a so-called orthogonal type total heat exchanger 20, and the air supply flow path 11 and the air discharge flow path 12 are orthogonal to each other. The total heat exchanger 20 is configured with porous base materials which include a hydrophilic resin or a flame retardant agent, for example, quadrangular-plate-shaped base materials including linear flow paths are alternately stacked while their directions are changed, and a quadrangular-prism-shaped total heat exchanger 20 is thereby configured in which the air supply flow path 11 and the air discharge flow path 12 are orthogonal to each other.
-
The total heat exchanger 20 of the present embodiment has heat conductivity and humidity permeability and is configured such that air flowing through the air supply flow path 11 and air flowing through the air discharge flow path 12 are capable of total heat exchange of sensible heat (temperature) and latent heat (humidity).
-
In the air supply flow path 11, air supply side heat exchanging means 21 is disposed on a downstream side of the total heat exchanger 20. The air supply side heat exchanging means 21 performs heating, cooling, and so forth for the air flowing through the air supply flow path 11.
-
In the air discharge flow path 12, air discharge side heat exchanging means 22 is disposed on a downstream side of the total heat exchanger 20. The air discharge side heat exchanging means 22 performs heating, cooling, and so forth for the air flowing through the air discharge flow path 12.
-
Each of the air supply side heat exchanging means 21 and the air discharge side heat exchanging means 22 is a so-called fin-and-tube type heat exchanger and has a pipe (not illustrated) through which a cooling-heating medium flows and a heat absorption-dissipation unit (not illustrated) which performs heat absorption and dissipation with respect to air.
-
The air supply side heat exchanging means 21 and the air discharge side heat exchanging means 22 are in series connected together and are connected with a cooling-heating medium circuit on the outside of the housing 10. The cooling-heating medium flows through the air supply side heat exchanging means 21 and the air discharge side heat exchanging means 22 via the cooling-heating medium circuit. In the air supply side heat exchanging means 21 and the air discharge side heat exchanging means 22, heat exchange is performed between air and the cooling-heating medium which pass through their internal portions, and air is heated and cooled.
-
Note that the air supply side heat exchanging means 21 is switchable to any of heating, cooling, and performing neither heating nor cooling. Further, the air discharge side heat exchanging means 22 is switchable to any of opposite conditions to the heating and cooling, which are performed by the air supply side heat exchanging means 21, and performing neither heating nor cooling.
-
A humidity controlling unit 24 is arranged on a downstream side of the air supply side heat exchanging means 21 and the air discharge side heat exchanging means 22. The humidity controlling unit 24 has humidity controlling means 25 and a humidity controlling means driving unit 26 such as an electric motor which rotates the humidity controlling means 25. The humidity controlling means 25 is humidity controlling means 25 which absorbs humidity when a temperature is low and which releases humidity when the temperature is high.
-
When air at a low temperature flows into the humidity controlling means 25, water in the air is adsorbed, and the air is dehumidified. Further, when air at a high temperature flows into the humidity controlling means 25, water adsorbed on the humidity controlling means 25 is freed to the air, and the air is humidified.
-
The humidity controlling means 25 is rotated in predetermined directions by driving the humidity controlling means driving unit 26. A rotor-shaped portion of the humidity controlling means 25 continuously moves between the air supply flow path 11 and the air discharge flow path 12. The humidity controlling means 25 dehumidifies air flowing through one of the air supply flow path 11 and the air discharge flow path 12 and humidifies air flowing through the other. The humidity controlling unit 24 performs humidity control for air flowing through the air supply flow path 11 on the downstream side of the total heat exchanger 20 and for air flowing through the air discharge flow path 12 on the downstream side of the total heat exchanger 20.
-
In the present embodiment, two humidity controlling means 25 are arranged side by side in width directions of the air supply side heat exchanging means 21 and the air discharge side heat exchanging means 22.
-
Note that as for respective rotation directions of the humidity controlling means 25, rotations may be performed in mutually opposite directions, or rotations may be made in the same direction.
-
In the internal portion of the housing 10, partition members 27 are provided which partition an upper area from a lower area of the total heat exchanger 20.
-
The partition members 27 include a function for separating the total heat exchanger 20 from the air supply flow path 11 in the air supply side heat exchanging means 21 and for separating the total heat exchanger 20 from the air discharge flow path 12 in the air discharge side heat exchanging means 22.
[1-1-2. Configurations of Heat Exchanging Means]
-
Next, a detailed description will be made about configurations of the air discharge side heat exchanging means 22 and the air supply side heat exchanging means 21.
-
Fig. 2 is a configuration diagram illustrating an outline of the air discharge side heat exchanging means 22 and the air supply side heat exchanging means 21.
-
As illustrated in Fig. 2, in the internal portion of the air discharge side heat exchanging means 22, cooling-heating medium piping 30 is provided through which the cooling-heating medium from an outdoor unit (not illustrated) flows.
-
The cooling-heating medium piping 30 of the air discharge side heat exchanging means 22 is configured with a plurality of pieces of cooling-heating medium piping 30 which extend in the width direction of the air discharge side heat exchanging means 22 (a perpendicular direction to the page of Fig. 3 or Fig. 4).
-
With the cooling-heating medium piping 30, air-discharge-side heat-exchanging-means inlet piping 31 and air-discharge-side heat-exchanging-means outlet piping 32 are connected.
-
In the present embodiment, the air-discharge-side heat-exchanging-means inlet piping 31 is connected with the cooling-heating medium piping 30 which is positioned in a lowest portion of the air discharge side heat exchanging means 22. Further, in the present embodiment, the air-discharge-side heat-exchanging-means outlet piping 32 is connected with the cooling-heating medium piping 30 which is positioned in a highest portion of the air discharge side heat exchanging means 22.
-
Similarly, the cooling-heating medium piping 30 of the air supply side heat exchanging means 21 is configured with a plurality of pieces of cooling-heating medium piping 30 which extend in the width direction of the air supply side heat exchanging means 21 (the perpendicular direction to the page of Fig. 3 or Fig. 4).
-
With the cooling-heating medium piping 30, air-supply-side heat-exchanging-means inlet piping 33 and air-supply-side heat-exchanging-means outlet piping 34 are connected.
-
In the present embodiment, the air-supply-side heat-exchanging-means inlet piping 33 is connected with the cooling-heating medium piping 30 which is positioned in a lowest portion of the air supply side heat exchanging means 21. Further, in the present embodiment, the air-supply-side heat-exchanging-means outlet piping 34 is connected with the cooling-heating medium piping 30 which is positioned in a highest portion of the air supply side heat exchanging means 21.
-
Fig. 3 and Fig. 4 are explanatory diagrams illustrating examples of a path of the cooling-heating medium by the cooling-heating medium piping 30 of the air discharge side heat exchanging means 22 and the air supply side heat exchanging means 21.
-
As illustrated in Fig. 3, for example, the path is configured such that the cooling-heating medium, which flows from the air-discharge-side heat-exchanging-means inlet piping 31 into the cooling-heating medium piping 30, flows from the cooling-heating medium piping 30 arranged on a lower surface side of the air discharge side heat exchanging means 22 to the cooling-heating medium piping 30 arranged on an upper surface side and thereafter again flows to the cooling-heating medium piping 30 arranged on the lower surface side.
-
Then, the cooling-heating medium which has flowed through the cooling-heating medium piping 30 is caused to flow out from the air-discharge-side heat-exchanging-means outlet piping 32 which is connected with the cooling-heating medium piping 30 positioned in the highest portion.
-
That is, a configuration is made such that the air-discharge-side heat-exchanging-means inlet piping 31 is connected with the cooling-heating medium piping 30 positioned in a lowest area of the air discharge side heat exchanging means 22, and the air discharge side heat exchanging means 22 is thereby configured such that the cooling-heating medium at a highest temperature is introduced from a lower area.
-
Further, as illustrated in Fig. 4, for example, the path is configured such that the cooling-heating medium, which flows from the air-discharge-side heat-exchanging-means inlet piping 31 into the cooling-heating medium piping 30, sequentially flows from the cooling-heating medium piping 30 arranged on the lower surface side of the air discharge side heat exchanging means 22 to the cooling-heating medium piping 30 in an upper area, is thereafter returned to the cooling-heating medium piping 30 arranged in a lowest area on the upper surface side of the air discharge side heat exchanging means 22, and sequentially flows from the cooling-heating medium piping 30 on the upper surface side of the air discharge side heat exchanging means 22 to the cooling-heating medium piping 30 in an upper area.
-
Then, the cooling-heating medium which has flowed through the cooling-heating medium piping 30 is caused to flow out from the air-discharge-side heat-exchanging-means outlet piping 32 which is connected with the cooling-heating medium piping 30 positioned in the highest portion.
-
In this case also, a configuration is made such that the air-discharge-side heat-exchanging-means inlet piping 31 is connected with the cooling-heating medium piping 30 positioned in the lowest area of the air discharge side heat exchanging means 22, and the air discharge side heat exchanging means 22 is thereby configured such that the cooling-heating medium at the highest temperature is introduced from a lower area.
-
As for those configurations of the cooling-heating medium piping 30 of the air discharge side heat exchanging means 22, the same applies to the cooling-heating medium piping 30 of the air supply side heat exchanging means 21.
-
That is, a configuration is made such that the air-supply-side heat-exchanging-means inlet piping 33 is connected with the cooling-heating medium piping 30 positioned in the lowest area of the air supply side heat exchanging means 21, and the air supply side heat exchanging means 21 is thereby configured such that the cooling-heating medium at the highest temperature is introduced from a lower area.
[1-2. Workings]
-
A description will be made about workings of the humidity controlling device 1 which is configured as described above.
-
In the humidity controlling device 1 of the first embodiment, the air supply fan 17, the air discharge fan 18, and the humidity controlling means driving unit 26 are driven, air (supplied air) flows through the air supply flow path 11, air (discharged air) flows through the air discharge flow path 12, and the humidity controlling means 25 rotates around a rotation axis as a center.
-
When respective flows of air flowing through the air supply flow path 11 and the air discharge flow path 12 flow into the total heat exchanger 20, those flows of air perform total heat exchange with each other and then flow out. In the air supply side heat exchanging means 21 and the air discharge side heat exchanging means 22 on the downstream side of the total heat exchanger 20, one of those flows of air is cooled, and the other of those flows of air is heated. Those flows of air then flow into the humidity controlling means 25.
-
When air which is cooled and is at a low temperature flows into the humidity controlling means 25, the air flows out from the humidity controlling means 25 in a dehumidified state.
-
On the other hand, when air which is heated and is at a high temperature flows into the humidity controlling means 25, the air flows out from the humidity controlling means 25 in a humidified state.
-
The air which results from humidity control by the humidity controlling means 25 is supplied or discharged to the air-conditioning target space or the outside.
-
For example, in a cooling operation, the cooling-heating medium at a low temperature flows through the cooling-heating medium piping 30 of the air supply side heat exchanging means 21, and the cooling-heating medium at a high temperature flows through the cooling-heating medium piping 30 of the air discharge side heat exchanging means 22.
-
Further, air which is introduced from the outside and flows through the air supply flow path 11 is cooled by the air supply side heat exchanging means 21, has its water being absorbed (dehumidified) by the humidity controlling means 25, and is supplied to the air-conditioning target space.
-
The humidity controlling means 25 which has absorbed water from the air in the air supply flow path 11 rotates in the predetermined direction and moves from the air supply flow path 11 to the air discharge flow path 12.
-
Meanwhile, air which is introduced from the air-conditioning target space and flows through the air discharge flow path 12 is heated by the air discharge side heat exchanging means 22 and heats the humidity controlling means 25. The humidity controlling means 25 which is heated by the air flowing through the air discharge flow path 12 is regenerated by releasing water and moves from the air discharge flow path 12 to the air supply flow path 11 again by its rotation. The water released to the air discharge flow path 12 by the humidity controlling means 25 is discharged to the outside.
-
The cooling-heating medium flowing through the air discharge side heat exchanging means 22 has its highest temperature at the air-discharge-side heat-exchanging-means inlet piping 31 and flows from the air-discharge-side heat-exchanging-means inlet piping 31 to the air-discharge-side heat-exchanging-means outlet piping 32 while giving heat to the air flowing through the air discharge flow path 12.
-
In the air discharge side heat exchanging means 22, the air-discharge-side heat-exchanging-means inlet piping 31 is positioned below the air-discharge-side heat-exchanging-means outlet piping 32. Thus, when the air flowing through the air discharge flow path 12 passes through the air discharge side heat exchanging means 22, air which passes through the air-discharge-side heat-exchanging-means inlet piping 31 having the highest temperature starts heating the humidity controlling means 25 at the moment when the humidity controlling means 25 moves from the air supply flow path 11 to the air discharge flow path 12.
-
That is, at the moment when the humidity controlling means 25 moves from the air supply flow path 11 to the air discharge flow path 12 by rotation in the predetermined direction, the humidity controlling means 25 is exposed to air having the highest temperature in the air flowing through the air discharge flow path 12 and is thereby heated.
-
Accordingly, in the cooling operation in which humidity has to be discharged to the outside, the humidity controlling means 25 is completely regenerated by speedily releasing humidity, a rapid start-up is thereby achieved, and performance for a humidity controlling amount can be improved.
-
Further, in the air-conditioning target space, in a case where humidity control is changed from dehumidification to humidification, switching is made between heating and cooling by the air supply side heat exchanging means 21 and the air discharge side heat exchanging means 22, the cooling-heating medium at a high temperature flows through the cooling-heating medium piping 30 of the air supply side heat exchanging means 21, and the cooling-heating medium at a low temperature flows through the cooling-heating medium piping 30 of the air discharge side heat exchanging means 22.
-
Further, the air which is introduced from the air-conditioning target space and flows through the air discharge flow path 12 is cooled by the air discharge side heat exchanging means 22, has its water being absorbed (dehumidified) by the humidity controlling means 25, and is discharged to the outside.
-
The humidity controlling means 25 which has absorbed water from the air in the air discharge flow path 12 rotates in the predetermined direction and moves from the air discharge flow path 12 to the air supply flow path 11.
-
Meanwhile, the air which is introduced from the outside and flows through the air supply flow path 11 is heated by the air supply side heat exchanging means 21 and heats the humidity controlling means 25.
-
The humidity controlling means 25 which is heated by the air flowing through the air supply flow path 11 is regenerated by releasing water and moves from the air supply flow path 11 to the air discharge flow path 12 again by its rotation. The water released to the air supply flow path 11 by the humidity controlling means 25 is supplied to the air-conditioning target space.
-
The cooling-heating medium flowing through the air supply side heat exchanging means 21 has its highest temperature at the air-supply-side heat-exchanging-means inlet piping 33 and flows from the air-supply-side heat-exchanging-means inlet piping 33 to the air-supply-side heat-exchanging-means outlet piping 34 while giving heat to the air flowing through the air supply flow path 11.
-
In the air supply side heat exchanging means 21, the air-supply-side heat-exchanging-means inlet piping 33 is positioned below the air-supply-side heat-exchanging-means outlet piping 34. Thus, when the air flowing through the air supply flow path 11 passes through the air supply side heat exchanging means 21, air which passes through the air-supply-side heat-exchanging-means inlet piping 33 having the highest temperature starts heating the humidity controlling means 25 at the moment when the humidity controlling means 25 moves from the air discharge flow path 12 to the air supply flow path 11.
-
That is, at the moment when the humidity controlling means 25 moves from the air discharge flow path 12 to the air supply flow path 11 by rotation in the predetermined direction, the humidity controlling means 25 is exposed to air having the highest temperature in the air flowing through the air supply flow path 11 and is thereby heated.
-
Accordingly, also in a heating operation in which air having humidity has to be supplied to the indoor space, similarly, the humidity controlling means 25 is completely regenerated by speedily releasing humidity, a rapid start-up is thereby achieved, and performance for the humidity controlling amount can be improved.
-
Further, as described above, when the cooling-heating medium at a low temperature flows from air-discharge-side heat-exchanging-means inlet piping 31 into the air discharge side heat exchanging means 22, the cooling-heating medium at a high temperature flows inward from the air-supply-side heat-exchanging-means inlet piping 33 of the air supply side heat exchanging means 21.
-
Thus, a temperature difference between the air-discharge-side heat-exchanging-means inlet piping 31 and the air-supply-side heat-exchanging-means inlet piping 33 becomes extremely large. Due to this temperature difference, condensation might occur to the partition members 27.
-
However, in the present embodiment, the air-discharge-side heat-exchanging-means inlet piping 31 is provided at the lowest portion of the air discharge side heat exchanging means 22, and the air-supply-side heat-exchanging-means inlet piping 33 is provided at the lowest portion of the air supply side heat exchanging means 21.
-
Thus, a distance between the air-discharge-side heat-exchanging-means inlet piping 31 and the air-supply-side heat-exchanging-means inlet piping 33 can be secured to some extent, and it becomes possible to suppress an influence of the temperature difference between the air-discharge-side heat-exchanging-means inlet piping 31 and the air-supply-side heat-exchanging-means inlet piping 33.
[1-3. Effects]

Thus, in the heating operation in which air having humidity has to be supplied to the indoor space, the humidity controlling means 25 can completely be regenerated by speedily releasing humidity, a rapid start-up is achieved, and performance for the humidity controlling amount can be improved.
-
Further, in the present embodiment, a plurality of humidity controlling means 25 configure the humidity controlling means 25 and are individually rotatable in the predetermined directions by transmitting motive power by the humidity controlling means driving unit 26.
-
Accordingly, performance for the humidity controlling amount can be improved for the plurality of humidity controlling means 25.
-
Further, in the present embodiment, the air discharge side heat exchanging means 22 includes the cooling-heating medium piping 30 through which the cooling-heating medium flows in the width direction of the air discharge side heat exchanging means 22, the air-discharge-side heat-exchanging-means inlet piping 31 is positioned in the lowest portion of the air discharge side heat exchanging means 22, and the air-discharge-side heat-exchanging-means outlet piping 32 is positioned in the highest portion of the air discharge side heat exchanging means 22.
-
Accordingly, because the air flowing through the air discharge flow path 12 passes through the air-discharge-side heat-exchanging-means inlet piping 31, which is positioned in the lowest portion of the air discharge side heat exchanging means 22 and has the highest temperature, and is sent to the humidity controlling means 25, the humidity controlling means 25 can be heated by air having the highest temperature. Thus, in the cooling operation in which humidity has to be discharged to the outside, the humidity controlling means 25 can completely be regenerated by speedily releasing humidity, a rapid start-up is achieved, and performance for the humidity controlling amount can be improved.
