Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dehumidifier using a dehumidifier rotor and a sensible heat exchanger.

[0002]

2. Description of the Related Art In general,
The dehumidifying device has a single processing-side path through which air to be processed to be dehumidified flows.In this single processing-side path, a sensible heat exchanger is arranged downstream of the dehumidification rotor. (See, for example, Japanese Patent Application Laid-Open No. 8-155247). By the way, the temperature of the air to be processed after passing through the dehumidification rotor increases due to the heat of adsorption. For this reason, the temperature difference between the air to be heat-exchanged in the sensible heat exchanger is reduced, and the exchange efficiency of the sensible heat exchanger is reduced.

Therefore, it is conceivable to dispose a sensible heat exchanger upstream of the dehumidifying rotor in a single path on the processing side. In this case, the air on the processing side whose temperature has been reduced by the sensible heat exchanger is removed by the dehumidifying rotor. , The efficiency of moisture absorption in the dehumidifying rotor deteriorates.

[0004] The present invention has been made in view of the above problems, and an object of the present invention is to provide a dehumidifier capable of preventing a decrease in efficiency of a dehumidifier rotor and a sensible heat exchanger.

[0005]

Means for Solving the Problems As means for solving the above problems, the invention according to claim 1 is characterized in that the first air passage of the first sensible heat exchanger and the second sensible heat exchanger are provided. A first air path, a second air path of the first sensible heat exchanger, a heating means, and a circulation path comprising a path of closed air sequentially circulated through the first air path of the dehumidifying rotor; A target path for introducing air outside the dehumidifier main body into the dehumidifier main body and discharging the air to the outside of the dehumidifier main body, wherein the target path is a first path via a second air path of the dehumidifier rotor. It is characterized by including a to-be-processed side path and a second to-be-processed side path which bypasses the dehumidification rotor and passes through the second air path of the second heat exchanger.

In this aspect, the water that has moved from the first processing-side path to the circulation path via the dehumidifying rotor is condensed in the first and second sensible heat exchangers, and the condensed water generated thereby is recovered. To dehumidify. In particular, since the dehumidifying rotor and the second sensible heat exchanger are arranged in separate treatment target paths,
There are the following advantages. That is, in the second sensible heat exchanger,
Since the air to be treated that has not been subjected to the temperature rise by the dehumidifying rotor can be introduced, the heat exchange efficiency of the second sensible heat exchanger can be increased. In addition, the air to be treated that has not been subjected to the temperature rise by the second sensible heat exchanger can be introduced into the dehumidifying rotor, so that the adsorption efficiency of the dehumidifying rotor can be increased.

[0007] The first and second paths to be processed may be branches that are branched in the dehumidifier body and then merged, or may be independent air paths.

According to a second aspect of the present invention, in the first aspect, a first air passage of the first sensible heat exchanger, a first air passage of the second sensible heat exchanger, and a first sensible heat exchanger are provided. A circulation path comprising a second air path of the heat exchanger, a heating means, and a closed air path which is sequentially circulated through the first air path of the dehumidification rotor; To the outside of the dehumidifier body after passing through the second air path of the dehumidifier rotor, and the air outside the dehumidifier body is introduced into the dehumidifier body to generate the second heat. And a cooling path for discharging the air to the outside of the dehumidifier after passing through the second air path of the exchanger.

According to this aspect, in the first aspect of the present invention, the second path to be processed is completely independent of the first path to be processed, and is configured as a cooling air path.
The same operation and effect as the embodiment of the invention described in claim 1 are obtained.

According to a third aspect of the present invention, in the first or second aspect, at least one of the first and second sensible heat exchangers is a counter-flow sensible heat exchanger. It is. In the case of the counter flow type, the heat exchange efficiency can be increased as compared with the orthogonal type sensible heat exchanger.

According to a fourth aspect of the present invention, in the third aspect, the counter-flow sensible heat exchanger includes a single heat transfer sheet having a cross-sectional waveform that rises and falls in one direction, and the heat transfer sheet. A heat exchange element including a frame holding a peripheral edge of the heat transfer sheet, and a first and a second, respectively, between the heat transfer sheet and the opposing heat transfer sheet surface traversing the corrugation along the top of the corrugation on both surfaces of the heat transfer sheet. A pair of partitioning materials for partitioning the air passage, each of the partitioning materials being disposed at an intermediate portion in a direction in which the top of the waveform extends, and an entrance of each of the air passages before and after the partitioning material along the direction in which the top of the waveform extends. And an outlet are provided.

In this embodiment, the inlet and the outlet are provided on both sides of the heat transfer sheet by using each partition material in a thickness space obtained by adding the thickness of the pair of partition members to the corrugated height of the single heat transfer sheet. The included air path can be partitioned at low cost.

[0013] Further, by flowing a pair of opposed flows sandwiching the heat transfer sheet through each of the air passages extending along the direction in which the top of the waveform extends, a heat exchange superior to the conventional orthogonal type sensible heat exchanger is achieved. Efficiency can be obtained. That is, when the value obtained by dividing the heat transfer area by the volume is equal to that of the conventional orthogonal type,
It has been found that the heat exchange efficiency can be improved, for example, by 3%.

Further, in each air path, the air introduction path leading to the inlet and the outlet path from the outlet are provided on the same side if they are a pair of ends along a direction crossing the top of the waveform. May be provided on the opposite side, and the degree of freedom of arrangement is high. Therefore, the configuration of the air passage that enters and exits the sensible heat exchanger can be simplified, and the dehumidifier can be downsized.

In this embodiment, in order to obtain a large heat exchange capacity, a thin rectangular parallelepiped whose length is increased in the first direction in which the top of the waveform extends or in the second direction across the top of the waveform. What is necessary is just a shape. With a thin rectangular parallelepiped shape, the size of the dehumidifier can be reduced.

In particular, the capacity of the present sensible heat exchanger can be improved by increasing the size of the heat transfer sheet in the direction transverse to the top of the corrugation while keeping the length in the direction in which the top of the corrugation extends. To improve the capacity of the sensible heat exchanger,
In addition, since it is not necessary to increase the length of the second air path, drain water flowing along each air path can be smoothly discharged from the air paths. Therefore, the drain water is unlikely to be a resistance of the air flowing through the air path, and the load on the motor of the blower can be reduced by reducing the pressure loss.
On the other hand, in the conventional orthogonal sensible heat exchanger, in order to improve the capacity, when the area of the heat transfer sheet is increased,
Regarding the flow direction of either one of the pair of cross flows, the air path becomes longer, and as a result, the drain water tends to stay in the air path and increase the pressure loss, thereby increasing the load on the motor of the blowing means. .

Here, the waveform of the cross section is a sine waveform,
U-shaped, V-shaped, rectangular, trapezoidal, and similar shapes can be exemplified.

According to a fifth aspect of the present invention, in the first or second aspect, the first and second sensible heat exchangers are paired thin in one direction and arranged in a direction orthogonal to the one direction. The counter-flow type sensible heat exchanger holds a single heat transfer sheet having a cross-sectional waveform that rises and falls in the one direction, and a peripheral edge of the heat transfer sheet. The first and second air passages are respectively defined between the heat exchange element including the frame and the corrugated tops of both sides of the heat transfer sheet along the corrugated tops, respectively, and opposing surfaces of the heat transfer sheet. A pair of partition members, each partition member being disposed at an intermediate portion in a direction in which the top of the corrugation extends, and an inlet and an outlet of each air passage provided before and after the partition member along the direction in which the top of the corrugation extends. It is characterized by having.

This embodiment has the same function and effect as the third aspect of the invention. Further, since the first and second sensible heat exchangers can be arranged side by side to maintain the overall thickness, downsizing of the dehumidifier can be achieved. In particular, since the ends of the two sensible heat exchangers can be brought close to each other, the configuration of the air passage connecting the two sensible heat exchangers can be simplified, and the size of the dehumidifier can be further reduced. .

According to a sixth aspect of the present invention, in the fifth aspect, the circulation path and the processing target are included in the contours of the first and second sensible heat exchangers viewed along the one direction. The side paths each include a pair of blowing means for generating an air flow.

The size of the dehumidifier is determined by the size of the sensible heat exchanger which is determined according to the dehumidifying capacity. Since a pair of air blowing means taking up a relatively large space is accommodated within the outline of the sensible heat exchanger, a dehumidifier having a very compact dehumidifying capacity can be achieved.

According to a seventh aspect of the present invention, in the sixth aspect, the pair of blowers include a pair of blowers arranged so as to sandwich the two-axis motor, and the two-shaft motor is included in the contour shape. It is characterized by being included.

In this embodiment, the motors for driving both the blowing fans are shared, and this motor is also contained within the above-described outline.
A very compact dehumidifier can be achieved with respect to the dehumidification capacity.

[0024] The embodiment of the invention described in claim 8 is the fifth invention.
In 6 or 7, the dehumidification rotor is included in the contour shapes of the first and second sensible heat exchangers as viewed along the one direction.

In this embodiment, since the dehumidifying rotor is also included in the above profile, a dehumidifying device which is very compact with respect to the dehumidifying ability can be achieved.

According to a ninth aspect of the present invention, in any one of the fifth to eighth aspects, the outline of the first and second sensible heat exchangers viewed along the one direction is included. And heating means.

In this embodiment, since the heating means is also included in the outline, a dehumidifier having a very compact dehumidifying capability can be achieved.

The aspect of the invention described in claim 10 is the fourth aspect of the invention.
In any one of the above items 9 to 9, water storage means for receiving and storing the dew condensation water is disposed below the counter-flow sensible heat exchanger, The air path is characterized by being arranged below the second air path with the heat transfer sheet interposed therebetween.

In the present embodiment, since the first air passage on the side where dew condensation occurs is disposed below, the dew water can be smoothly discharged from the sensible heat exchanger. Dew does not increase pressure loss.

The outlet space 36 associated with the second sensible heat exchanger 3 has an outlet 41 at the end opposite to the inlet 39.

The air passage partitioning member 25 also serves as the drain pan 11 for receiving dew water generated in the circulating air passing through the first air passages 2a and 3a of each heat exchange element 19.
For this reason, a plurality of fine water drain holes 42 for dropping the condensed water that has been received toward the water storage tank 12 below are dispersedly arranged in the air path partitioning member 25.

This drain water is received by the drain hole 4
2 and is stored in the lower water storage tank 12.

Next, FIG. 7 is a schematic plan view of the present dehumidifier A. Referring to FIG. 7, the first and second sensible heat exchangers 2 and 3 are viewed from one direction Z (a direction perpendicular to the paper surface and corresponds to the up-down direction) and the first and second sensible heat exchangers 2 and 3. The outline of the heat exchangers 2 and 3 includes a pair of blower fans 8 and 9, a double-axis motor 10, a dehumidifying rotor 5, and a heater 4.

In this embodiment, the first processing-side route B
The moisture that has moved from 1 to the circulation path R via the dehumidifying rotor 5 is condensed in the first and second sensible heat exchangers 2 and 3, and the resulting condensed water is collected in the water storage tank 12 to dehumidify. I do.

Since the dehumidifying rotor 5 and the second sensible heat exchanger 3 are respectively arranged on the individual treatment-side paths B1 and B2, the second sensible heat exchanger 3 receives the temperature rise by the dehumidifying rotor 5. As a result, it is possible to increase the exchange efficiency of the second sensible heat exchanger 3. Also,
Since the air to be treated which has not been subjected to the temperature rise by the second sensible heat exchanger 3 can be introduced into the dehumidifying rotor 5, the adsorption efficiency of the dehumidifying rotor 5 can be increased.

Further, the first and second sensible heat exchangers 2, 3
Is a counter flow type, so that the heat exchange efficiency can be increased as compared with a cross-flow type sensible heat exchanger.

In particular, the counterflow type using the single heat transfer sheet 20, the frame 21, and the pair of partitioning agents 22 has the following advantages. That is, a pair of partitioning materials 2 are provided at the height of the waveform of the single heat transfer sheet 20.
In the thickness space corresponding to the sum of the thicknesses of the heat transfer sheets 20 and 22, the entrances 2 a
1,2b1,3a1,3b1 and outlets 2a2,2b
Wind paths 2a, 2b, 3a, 3 including 2, 3a2, 3b2
b can be partitioned at low cost.

Each air path 2a, 2b; 3a, 3b extending along the first direction P1 in which the top 23 of the waveform extends.
By flowing a pair of opposed flows sandwiching the heat transfer sheet 20, it is possible to obtain a heat exchange efficiency superior to a conventional orthogonal sensible heat exchanger. That is, it has been found that when the value obtained by dividing the heat transfer area by the volume is equal to that of the conventional orthogonal type, the heat exchange efficiency can be improved by, for example, 3%.

Further, each air passage 2a, 2b, 3a, 3b
, The air introduction paths (introduction ports 37, 46, 39, 31) leading to the above-mentioned inlets 2a1, 2b1, 3a1, 3b1;
The outlets (outlets 38, 47, 41, 32) from the outlets 2a2, 2b2, 3a2, 3b2 are the same if they are a pair of ends along the second direction P2 crossing the top 23 of the waveform. It may be provided on the side, or may be provided on the opposite side (this embodiment has been described based on the example provided on the opposite side), and the degree of freedom of arrangement is high. Therefore, it is possible to simplify the configuration of the air passage that enters and exits the sensible heat exchangers 2 and 3, and to reduce the size of the dehumidifier A.

In order to obtain a large heat exchange capacity, the top portion 23 of the corrugation extends in the first direction P1 or the top portion 2 of the corrugation.
3 may be formed in a thin rectangular parallelepiped shape having a longer length in the second direction P2 crossing the third direction. If the shape is a thin rectangular parallelepiped, the size of the dehumidifier A can be reduced.

In particular, the improvement of the capacity of the sensible heat exchangers 2, 3
This is possible by increasing the size of the heat transfer sheet 20 in the second direction P2, which crosses the top of the waveform, while keeping the length of the first direction P1 in which the top of the waveform extends. That is,
Since it is not necessary to increase the length of the first and second air passages 2a, 2b; 3a, 3b in order to improve the capacity of the sensible heat exchangers 2, 3, the drain water flowing along each air passage is not required. The wind path 2
a, 2b; can be smoothly discharged from 3a, 3b. Therefore, the drain water flows through the air passages 2a, 2b; 3a,
The resistance of the air flowing through 3b is small, and the load on the two-axis motor 10 for driving the blower fans 8, 9 can be reduced by reducing the pressure loss. On the other hand, in the conventional orthogonal type sensible heat exchanger, when the area of the heat transfer sheet is increased in order to improve the capacity, the air path becomes longer in one of the flow directions of the pair of cross flow. ,as a result,
Drain water tends to stay in the air passage and increase pressure loss, increasing the load on the motor of the blower.

Further, the first and second sensible heat exchangers 2,
3 are arranged along the direction (first direction P1 in the present embodiment) orthogonal to the one direction Z in which the top portion 23 of the waveform rises and falls, so that the overall thickness can be maintained. A can be reduced in size. In particular, both sensible heat exchangers 2,
Since the ends of the sensible heat exchangers 2 and 3 can be brought close to each other, the configuration of the air path connecting the two sensible heat exchangers 2 and 3 can be simplified, for example, like the communication passage 40 and the communication duct 48.
The size of the dehumidifier A can be further reduced.

The size of the dehumidifier A is determined by the size of the sensible heat exchangers 2 and 3 determined according to the dehumidifying capacity. As shown in FIG. 7, since it is contained within the contours of the sensible heat exchangers 2, 3, a dehumidifier A which is very compact with respect to the dehumidification capacity can be achieved.

In addition, the drive motors for both the blower fans 8 and 9 are shared by the two-axis motor 10, and this motor 10 is also contained within the above-described outline. Can be achieved. Furthermore, since the dehumidification rotor 5 is also included in the above-mentioned outline shape, a dehumidification device more compact in dehumidification capacity can be achieved. Moreover, since the heater 4 is also included in the above-mentioned outline shape,
A more compact dehumidifier can be achieved with respect to the dehumidification capacity.

Further, since the first air passages 2a and 3a on the side where dew condensation occurs in the counter-flow type sensible heat exchangers 2 and 3 are disposed below, the dew condensation water is transferred to the sensible heat exchangers 2 and 3. 3 can be discharged smoothly. Dew does not increase pressure loss. Note that the present invention is not limited to the above-described embodiment. For example, each partition wall 27,
An elastic member such as rubber or urethane resin may be interposed between 43, 51, and 52 and the corresponding partition member 22 in order to increase airtightness. Further, the partition member 22 is divided into the partition walls 27 and 4.
3, 51, 52 may be fixed. Also in this case, the partition member 22 is separated from the partition wall 2 via the elastic member.
7, 43, 51 and 52 are preferably fixed.

In the above-described embodiment, the outline of the sensible heat exchangers 2 and 3 in plan view includes all of the blower fans 8 and 9, the dual-axis motor 10, the dehumidifying rotor 5, and the heater 4. However, the present invention is not limited to this, and it is sufficient that at least the blowing fans 8 and 9 are included. More preferably, at least two components including the blowing fans 8 and 9 are included among the four components described above. If so, sufficient miniaturization can be achieved.

Next, FIG. 8 shows another embodiment of the present invention. Referring to FIG. 8, the present embodiment is different from the embodiments of FIGS.
9 is a point where the direction P1 in which the top of the waveform extends and the direction P2 crossing the waveform are interchanged. That is, in the embodiment of FIG. 4, the direction P2 crossing the waveform is parallel to the direction in which the rotation axis 13 of the dehumidifying rotor 5 in FIG. 3 extends, but in the present embodiment, the direction P1 in which the top of the waveform extends. Are parallel to the direction in which the rotation axis 13 of the dehumidifying rotor 5 extends. Also,
With the change in the direction, the arrangement of the partition members 22 and the form of the air path forming member are changed.

More specifically, the air path partition members 24, 25, 26 and the communication duct 48 in the embodiment of FIG. 4 are eliminated, and new air path partition members 55, 56 are provided. The partition member 22 is arranged such that one sheet straddles both heat exchange elements 19. Further, the pair of heat exchange elements 19 are configured by dividing the upper and lower surfaces of a single heat exchange element by partition members 22, 22, and the frames of both heat exchange elements 19 are shared. . In order to make this possible, the partition portions 57 extend from the center of the partition member 22 to the frame along the direction P1 in which the top of the waveform extends.

The air path partition member 55 has an inlet 59 and an outlet 60, and is formed of a hollow duct that communicates the outlet 3a2 from the air path 3a and the inlet 2b1 to the air path 2b. The air path partitioning member 55 covers the outlet 3a2 from the air path 3a on the lower surface of the second heat exchange element 19B and connects its own inlet 59 to the outlet 3a2 from the air path 3a, while the first heat exchange element The outlet 60 is connected to the inlet 2b1 to the air passage 2b so as to cover the inlet 2b1 to the air passage 2b on the upper surface of the element 19A.

The air path partitioning member 56 is formed of a rectangular parallelepiped box having an open upper surface. The air path partitioning member 56 covers the outlet 2a2 from the air path 2a on the lower surface of the first heat exchange element 19A and the inlet 3a1 to the air path 3a on the lower surface of the second heat exchange element 19B. The outlet 2a2 from 2a and the inlet 3a1 to the air path 3a communicate.

With such a configuration, in the closed system circulation path R, the air path 5a of the dehumidifying rotor 5, the air path 2a on the lower surface of the first heat exchange element 19A, the air path partition member 56, the second heat The air path 3a on the lower surface of the exchange element 19B, the air path partition member 55, the air path 2b on the upper surface of the first heat exchange element 19A, the blower fan 8, and the heater 4 are sequentially provided.
The air is circulated to the air passage 5a of the dehumidifying rotor 5.

On the other hand, in the second processing-side path B2 included in the processing-side path B, the air introduced from the suction port 6
The air is discharged from the outlet 7 via the air passage 3b on the upper surface of the second heat exchange element 19B and the blower fan 9.

In the present embodiment, the same functions and effects as those of the embodiment shown in FIGS. Further, the sensible heat exchanger 2,
With respect to the third heat exchange elements 19A and 19B, by dividing the portion covered by the partition member 22 and the portion covered by the air path partition members 55 and 56, the structure for partitioning the air path can be simplified.

Condensation water generated in the air passage 2a on the lower surface of the first heat exchange element 19A falls smoothly because the inlet and outlet of the air passage 2a are open downward, and the first heat exchange is performed. The water is discharged from the element 19A and stored in the lower water storage tank 12. Also, the second heat exchange element 1
Condensed water generated in the air passage 3a on the lower surface of the air passage 9B is discharged through drain holes 58 formed in the air passage partition members 55 and 56, and is stored in the lower water storage tank 12.

The present invention is not limited to the above embodiments. For example, in each of the above embodiments,
Although the first and second paths B1 and B2 were merged after branching, the two paths were completely separated from each other,
As shown in FIG. 9, the former can be configured as the processing-side path B, and the latter can be configured as the cooling air path C. Reference numeral 61 denotes a blower fan for a cooling air passage. In this case, the same operation and effect as those of the above embodiments can be obtained.

In addition, various changes can be made within the scope of the present invention.

[0080]

According to the first aspect of the present invention, since the dehumidifying rotor and the second sensible heat exchanger are arranged on the individual passages to be processed, the temperature rise due to the dehumidifying rotor is provided to the second sensible heat exchanger. As a result, it is possible to introduce untreated air on the processing side, thereby improving heat exchange efficiency. Further, since the air to be treated which has not been subjected to the temperature rise by the second sensible heat exchanger can be introduced into the dehumidifying rotor, the adsorption efficiency of the dehumidifying rotor can be increased.

According to the second aspect of the present invention, the same effects as those of the first aspect of the invention can be obtained.

According to the third aspect of the present invention, a counter-flow sensible heat exchanger is used.
Heat exchange efficiency can be increased.

The air path including the entrance and the exit can be partitioned at low cost.

Further, a heat exchange efficiency superior to that of the conventional orthogonal type sensible heat exchanger can be obtained. Further, in each air path, the air introduction path to the inlet and the outlet path from the outlet may be provided on the same side as long as they are a pair of ends along a direction crossing the top of the waveform. It may be provided on the side, and the degree of freedom of arrangement is high. Therefore, the configuration of the air passage that enters and exits the sensible heat exchanger can be simplified, and the dehumidifier can be downsized.

Further, since it is not necessary to increase the length of the first and second air passages in order to improve the capacity of the sensible heat exchanger, drain water flowing along each air passage can be smoothly discharged from the air passages. Can be discharged. Therefore, the drain water is unlikely to be a resistance of the air flowing through the air path, and the load on the motor of the blower can be reduced by reducing the pressure loss.

According to the fifth aspect of the invention, the same operation and effect as those of the third aspect of the invention can be obtained. Furthermore, since the first and second sensible heat exchangers can be arranged side by side to maintain the overall thickness,
The size of the dehumidifier can be reduced. In particular, since the ends of the two sensible heat exchangers can be brought close to each other, the configuration of the air passage connecting the two sensible heat exchangers can be simplified, and the size of the dehumidifier can be further reduced. .

The invention according to claim 6 has the following advantages. The size of the dehumidifying device is determined by the size of the sensible heat exchanger determined according to the dehumidifying capacity. Since a pair of air blowing means taking up a relatively large space is accommodated within the outline of the sensible heat exchanger, a dehumidifier having a very compact dehumidifying capacity can be achieved.

According to the seventh aspect of the present invention, the motors for driving both the blowing fans are shared, and the motors are also contained within the above-mentioned outline, so that a dehumidifier having a very compact dehumidifying capacity can be achieved.

According to the eighth aspect of the present invention, since the dehumidifying rotor is included in the outline, a dehumidifying device which is very compact with respect to the dehumidifying ability can be achieved.

According to the ninth aspect of the present invention, since the heating means is also included in the outline, a dehumidifier having a very compact dehumidifying capability can be achieved.

According to the tenth aspect of the present invention, since the first air passage on the side where dew condensation occurs is disposed below, the dew water can be smoothly discharged from the sensible heat exchanger. Dew does not increase pressure loss.
