Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moisture-absorbing dehumidifier for dehumidifying air taken in by a moisture absorbing section and discharging the air into a room or the like.

[0002]

2. Description of the Related Art A conventional hygroscopic dehumidifier is configured to dehumidify air taken in from an air inlet with a hygroscopic rotor and discharge dry air into a room or the like from an air outlet while passing heated air through the hygroscopic rotor. Thus, the moisture adsorbed is removed to regenerate the moisture absorbing rotor in a state capable of absorbing moisture, and the continuous dehumidifying operation is performed while simultaneously performing the dehumidification and the regeneration. (See, for example, JP-A-60-50328 and JP-A-63-
286635).

[0003] More specifically, as shown in FIG.
In order to remove (dehumidify) water contained in room air, a conventional moisture-absorbing dehumidifier uses a rotary moisture-absorbing rotor 3 having a moisture absorbent.
First, the relatively low-temperature room air taken in from the air inlet 1 is first passed through the orthogonal heat exchanger 2, and then the moisture absorbing zone 3a of the rotating moisture absorbing rotor 3 (the portion other than the hatched portion, approximately 3/4 area), where the moisture in the air is adsorbed by the moisture absorbing rotor 3 to dehumidify the air, and the dried air is discharged from the blower fan 4 into the room through the air outlet 5. As a result, the indoor air is gradually dehumidified into dry air.

On the other hand, a circulating system for circulating air by a blower fan 6 is provided in order to regenerate the moisture-absorbing rotor 3 to a state capable of absorbing moisture. In this system, the air sent by the blower fan 6 is heated by the heater 7, and the high-temperature air is guided to the dehumidifying / regenerating zone 3 b of the moisture absorbing rotor 3 (shaded area, approximately 1/4 area). .

[0005] In this case, the moisture absorbing rotor 3 is
The portion adsorbing the moisture in a is rotated and moved to the dehumidifying regeneration zone 3b, and the moisture of the moisture absorbing rotor 3 is dissipated by the high-temperature air in the dehumidifying regeneration zone 3b to regenerate the moisture absorbing rotor 3 in a moisture absorbing state. I do. Therefore, the moisture absorbing rotor 3 is regenerated in a moisture absorbing state while continuously rotating at a predetermined speed, and can always exhibit the moisture absorbing function in the moisture absorbing zone 3a.

Here, the humid high-temperature and high-humidity air discharged from the moisture-absorbing rotor 3 is guided to the orthogonal heat exchanger 2 and exchanges heat with relatively low-temperature air taken in from the air intake port 1. Is condensed and stored in the drain pan 8 as drain water. The air from which the moisture has been removed is heated again by the heater 7 and used for the subsequent regeneration of the moisture absorbing rotor 3.

[0007] In this specification, the term "moisture absorption" means that moisture in the air is adsorbed by the desiccant, and the term "dehumidification" means that moisture is removed from the air.

[0008]

As described above, the conventional moisture-absorbing dehumidifier has a system for supplying main dehumidified air,
A high-temperature air circulation system for regenerating the moisture absorbing rotor 3 is provided, and air dehumidification and regeneration of the moisture absorbing rotor 3 are simultaneously and continuously performed.

However, since the circulating system of the high-temperature air for regenerating the moisture absorbing rotor 3 is in a closed loop, when the apparatus is continuously operated, particularly the heat applied by the heater 7 is gradually accumulated, and the temperature of the circulating system rises. I do. Further, the temperature of the dehumidifying / regenerating zone 3b of the moisture absorbing rotor 3 to which high-temperature air is sent is increased, and the portion moved to such a region and subjected to the dehumidifying / regenerating operation is maintained at a high temperature without decreasing its temperature. Is likely to be rotated to enter the moisture absorption zone 3a.

Therefore, the intake air taken in from the air intake 1 is first heat-exchanged with the air circulating for regeneration in the orthogonal heat exchanger 2 to become high temperature, and thereafter, becomes high in temperature.
Therefore, there is a problem that the temperature of the exhaust gas becomes extremely high because the gas is blown out after passing through the moisture absorption zone 3a.

Further, the temperature of the moisture absorbing rotor 3 may be increased as a whole, and the moisture absorbing performance in the moisture absorbing zone 3a may be reduced.

Further, since the air heated by the heater 7 is circulated only for the regeneration of the moisture absorbing rotor 3, there is a drawback that the air sterilized by heating cannot be supplied to the room.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a moisture-absorbing dehumidifier capable of dehumidifying while keeping the exhaust gas temperature low and adding various functions such as sterilization. Aim.

[0014]

According to a first aspect of the present invention, there is provided an air conditioner, wherein air taken in from an air intake is dehumidified by a moisture absorbing portion and discharged from an air outlet, while the air absorbing portion absorbs the air. In the moisture absorbing type dehumidifying apparatus in which the adsorbed moisture is removed by passing heated air through the air to regenerate the moisture absorbing section in a moisture absorbing state, the first air intake of the air intake is connected to the first of the moisture absorbing section. A first air flow path formed through a region to an air outlet, and a second air inlet of the air inlet formed through a heat exchange unit that exchanges heat with passing air to an air outlet. A second air flow path, a heater for heating the passing air, and a second area of the moisture absorbing section pass in this order, and the heat exchange section passes through the heat exchange section so as to be substantially orthogonal to the second air flow path to an air outlet. A third air flow path to be formed; Characterized in that it.

[0015] In the invention thus configured, the air taken in from the air inlet is blown into the first air flow path, and the air flowing through the first air flow path is supplied to the first area of the moisture absorbing portion. When passing through the inside, moisture is adsorbed and dried to become low-humidity air, which is discharged into the room from an air outlet. The air flowing in the third air flow path is heated by the heater and flows to the second area of the moisture absorbing section, and the heated high-temperature air evaporates the moisture in the moisture absorbing section, so that the moisture absorbing section that has absorbed the moisture can absorb moisture. Played to the state. The evaporated moisture in the moisture absorption section is
Along with the heated air, it becomes hot and humid air and flows to the downstream heat exchanger. On the other hand, the air taken in from the air inlet is also blown into the second air flow path, and the air flowing in the second air flow path flows to the downstream heat exchanger, and the air flows in the third air flow path. Along with the flow of the high-temperature and high-humidity air flowing through the heat exchanger, the two flow as a cross flow in the heat exchanger, and heat is efficiently exchanged. Accordingly, the high-temperature and high-humidity air flowing in the third air flow path is cooled, and the moisture contained therein is dew-condensed, so that the air becomes low-humidity air and is discharged from the air outlet into the room. As described above, since each air flow path has an open loop while having the function of regenerating the moisture absorbing section, the air temperature is kept low and dehumidification is achieved by combining the air flow paths.

According to a second aspect of the present invention, in the moisture absorbing type dehumidifying device according to the first aspect, the third air flow path is located downstream of the first air flow path. It is characterized in that it branches from the first branch point, passes through the third region of the moisture absorbing section, and then passes through the heater, the second region of the moisture absorbing section and the heat exchange section to the air outlet in order.

According to the invention having such a configuration, a part of the air taken in from the air inlet branches off at the first branch point located on the downstream side of the moisture absorbing portion of the first air flow path, and the third air flows into the third branch point. It flows into the air channel. The relatively low-temperature air that has flowed into the third air flow path passes through the third region of the moisture absorbing portion, whereby the temperature of the moisture absorbing portion can be reduced.

According to a third aspect of the present invention, in the moisture absorption type dehumidifying apparatus according to the second aspect, the flow rate to the air flow path branched to the first branch point can be adjusted to a predetermined ratio. It is characterized in that one flow path adjusting means is provided.

According to the invention having such a configuration, by adjusting the first flow path adjusting means, a dehumidifying mode in which the function of regenerating the moisture absorbing portion is provided to perform dehumidification, and a single flow passing through the heater is provided. A sterilization mode and a circulator mode in which intake air is blown out from an air outlet through an air flow path can be selected and executed.

According to a fourth aspect of the present invention, in the moisture absorbing type dehumidifying device according to the second aspect, the first air flow path is branched from a second branch point located on the upstream side of the moisture absorbing section. A fourth air passage merging between the moisture absorbing portion and the heater in the third air passage, and a third branch point located between the heater and the moisture absorbing portion in the third air passage. A fifth air flow path that branches off from the air outlet directly to the air outlet, and at the second branch point and the third branch point,
A second flow path adjusting means and a third flow path adjusting means capable of adjusting a flow rate to each branched air flow path at a predetermined ratio are provided.

[0021] In the invention thus configured, in the sterilization mode, the second flow path adjusting means closes the first air flow path and the third flow path adjusting means closes the third air flow path. Set to position. Therefore, the air from the first air flow path flows into the third air flow path via the fourth air flow path, passes through the heater, is sterilized by heating, and is blown out as it is via the fifth air flow path, That is, an airflow is formed that discharges out of the apparatus without passing through the moisture absorbing section.

According to a fifth aspect of the present invention, in the moisture absorbing type dehumidifying device according to the second aspect, the fourth dehumidifying device is located between the moisture absorbing part and the heat exchanging part in the third air flow path. A fourth flow path adjustment that has a sixth air flow path that is formed from the branch point to the air outlet directly and that can adjust the flow rate to the branched air flow path at the fourth branch point at a predetermined ratio. Means are provided.

In the invention configured as described above, in the sterilization mode, the fourth flow path adjusting means is set at a position where the third air flow path is closed. Therefore, the air branched from the first air flow path and flowing into the third air flow path passes through the heater, is sterilized by heating, passes through the moisture absorbing portion, and then passes through the sixth air flow as it is.
It is blown out through the air flow path.

According to a sixth aspect of the present invention, in the moisture absorption type dehumidifying apparatus according to the first aspect, the third air flow path is located downstream of the heat exchange section of the second air flow path. A fifth branch point is formed, and is formed to the air outlet through the heater, the second region of the moisture absorbing section, and the heat exchange section in order.

According to the invention having such a configuration, since the air passages are open loop while providing the function of regenerating the moisture absorbing portion, the exhaust air temperature is reduced by combining the air passages. Can be suppressed.

FIG. 2 is a system airflow diagram of the device, and FIG. 3 is a schematic diagram three-dimensionally showing the airflow of the device.

The illustrated moisture-absorbing dehumidifying apparatus has a moisture-absorbing rotor 14 as a rotationally driven moisture-absorbing section having a moisture-absorbing agent for removing (dehumidifying) water contained in air, and the moisture-absorbing rotor 14 is in a state capable of absorbing moisture. The heater 13 that heats the passing air to regenerate the air and heat exchanges with the passing air to cool the hot and humid air discharged from the moisture absorbing rotor 3 and condense the moisture in the heated air as dew water. And a heat exchanger 15 as a heat exchange section to be performed.

More specifically, the hygroscopic rotor 14 is formed by mixing a hygroscopic agent made of powdered silica gel or the like into a thin plate made of paper or the like, and forming this into a honeycomb-shaped circle having a predetermined length in the axial direction. Although it has a columnar shape, the present invention is not limited to this, and may have a structure in which a large number of silica gel particles are housed in a porous plate. During operation of the apparatus, the moisture absorbing rotor 14 is rotated at a predetermined speed by driving means such as a motor (not shown). The heat exchanger 15 is provided with, for example, a thin plate-shaped or corrugated heat transfer fin made of a member having good heat conductivity, and has a large contact area with the passing air.

In the moisture absorption type dehumidifier of the present embodiment,
The three air flows from the air inlet 10 to the air outlet 11 are each configured to form an open loop.

That is, this moisture absorbing type dehumidifying apparatus has a first air flow path A formed from a first air inlet 10a to a first air outlet 11a through a moisture absorbing zone 14a as a first region of a moisture absorbing rotor 14. And a second air flow path B formed from the second air inlet 10b to the second air outlet 11b through the heat exchanger 15 and a regeneration zone 14b as a second area of the heater 13 and the moisture absorbing rotor 14. A third air flow path C is formed in this order, and is formed up to the third air outlet 11c through the heat exchanger 15 so as to be substantially orthogonal to the second air flow path B.

The third air flow path C branches from a first branch point 21 located on the downstream side of the moisture absorption rotor 14 of the first air flow path A to form a cooling zone 14c as a third area of the moisture absorption rotor 14. After that, the heater 13, the regeneration zone 14 b of the moisture absorbing rotor 14, and the heat exchanger 15 are sequentially formed to the third air outlet 11 c.

Therefore, the heat exchanger 15 is located at a position where the flow of high-temperature and high-humidity air discharged from the regeneration zone 14b of the moisture absorbing rotor 3 and the flow of low-temperature air taken in from the second air inlet 10b are orthogonal to each other. Function as a so-called orthogonal heat exchanger disposed in Drain water cooled and condensed in the orthogonal heat exchanger 15 is stored in a drain pan 17. Note that the cooling air introduced into the heat exchanger 15 is not limited to only indoor air, and outdoor air may be used.

In the vicinity of the first air inlet 10a, there is provided a first blower fan 12a for taking in air and flowing the air to the air flow path A. Downstream of the first blower fan 12a, a first blower fan 12a is provided. The moisture absorption zone 14a is located. On the other hand, a second blower fan 12b is provided near the second air outlet 11b to take in air and flow it into the air flow path B. Note that a filter 18 for dust removal is detachably installed on the upstream side of the air intake 10.

The operation of the thus configured moisture absorbing dehumidifier will be described. When the hygroscopic dehumidifier is put into operation, the first
The blower fan 12a is operated, and the air taken in from the first air inlet 10a is removed by the filter 18 and is blown into the first air passage A. When the air flowing in the first air flow path A passes through the moisture absorption zone 14a of the moisture absorption rotor 14, the moisture is adsorbed and dried, becomes low humidity air, and is discharged indoors from the first air outlet 11a. You.

A part of the air taken in from the first air inlet 10a branches at a first branch point 21 located downstream of the moisture absorption rotor 14 of the first air flow path A, and the third air flow path C Flows in A high-temperature portion regenerated in a regenerating zone 14b of the moisture absorbing rotor 14 to be described later rotates and moves to the cooling zone 14c, and the relatively low-temperature air flowing into the third air flow path C is removed by the moisture absorbing rotor. 14 cooling zone 14c. Thereby, the moisture absorption rotor 14
Can be lowered, and moisture can be absorbed by the moisture absorbing rotor 14 in a low temperature state, so that the moisture absorbing efficiency in the moisture absorbing zone 14a is improved.

The air flowing in the third air flow path C passing through the cooling zone 14c of the moisture absorbing rotor 14 is heated by the heater 13 and flows to the regeneration zone 14b of the moisture absorbing rotor 14. At this time, as described above, the portion of the moisture absorption zone 14a of the moisture absorption rotor 14 that has absorbed moisture is the regeneration zone 14a.
In the regeneration zone 14b of the moisture absorbing rotor 14, the moisture in the moisture absorbing rotor 14 is evaporated by the heated high-temperature air. In this way,
The moisture-absorbing rotor 14 that has absorbed moisture is regenerated to a moisture-absorbable state, and can again absorb moisture in the air. The evaporated moisture in the moisture absorption rotor 14 flows into the downstream heat exchanger 15 as high-temperature and high-humidity air together with the heated air.

On the other hand, the second blowing fan 12b is operated,
The air taken in from the second air inlet 10b is filtered by the filter 1
8 and the air is blown into the second air flow path B. The air flowing in the second air flow path B flows to the heat exchanger 15 on the downstream side, and together with the flow of the high-temperature and high-humidity air flowing in the third air flow path C, both air flow directly in the heat exchanger 15. It flows as an alternating current and heat is exchanged efficiently. Therefore, the high-temperature and high-humidity air flowing in the third air flow path C is cooled, and the moisture contained therein is dew-condensed, so that it becomes low-humidity air and is discharged into the room from the third air outlet 11c. . The condensed water condensed here is stored in the drain pan 17.

As described above, in this embodiment, since each air flow path is open loop while providing the function of regenerating the moisture absorbing rotor, it is arranged in a closed loop for regeneration of the moisture absorbing rotor as in the prior art. The temperature is not raised by both the heat exchanger and the moisture absorption rotor, and the air passages are combined, so that the exhaust temperature can be kept low and dehumidification can be achieved.

Further, since the air flow path in which the heater is arranged is also opened from the air outlet, it is possible to easily supply sterilized clean air into the room.

Further, since each air flow path is open loop,
Various controls such as a single flow or a combined flow are possible.
