DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner and an air conditioner, and more particularly, it is possible to adjust the temperature and humidity of an air-conditioned system such as a room or another air conditioner with low energy consumption. The present invention relates to an air conditioner and an air conditioner using the same. The present air conditioner is suitably used not only for ordinary houses, offices and factories, but also for automobiles and railway vehicles.

[0002]

2. Description of the Related Art In recent years, it has been recognized that improvement in the comfort of a living space and a work space is a very important and natural requirement, and is not limited to ordinary houses, offices, factories, but also mobile bodies such as automobiles and railway vehicles. Even air conditioners are widely spread.
On the other hand, since the oil shock, various attempts have been made to reduce the energy consumption of various devices, and the energy consumption of air conditioners has also become an important issue, but global environmental issues are particularly discussed. At present, the importance and urgency of reducing the energy consumption of such air conditioners is only increasing.

[0003]

In consideration of such a background, first, a vehicle air conditioner, which is an example of the air conditioner, will be considered. Currently, most domestic vehicles are equipped with an air conditioner as one of the comfort equipment. It is well known that the use of such air conditioners affects the fuel efficiency of vehicles. At present, fuel efficiency of vehicles is being reduced in consideration of the environment, reducing the energy consumption of air conditioners is an important issue. Has become.

Further, the current air conditioner utilizes a general refrigeration cycle (cooler) and engine waste heat (heater), and has a problem that a large amount of energy is consumed particularly for dehumidification. . In other words, air is cooled by a cooler during cooling / dehumidification in summer,
Since it is necessary to lower the dew point for dehumidification, the air is cooled excessively to prepare low-temperature, low-humidity air, and then heated (reheated) with a heater to bring the low-temperature, low-humidity air to the desired temperature before the room It is blowing to. Therefore, there is a problem that a large cooling capacity is required, which leads to an increase in energy consumption and an increase in the size of the apparatus. Further, in fuel-efficient vehicles and electric vehicles, which are expected to become more widespread in the future, there is also a problem that it is difficult to use the waste heat of the engine, and the energy for reheating also becomes a large burden.

Next, as another example, consider a dehumidifier used in general houses, offices, factories and the like. Currently available dehumidifiers can be classified into wet dehumidifiers that use the same refrigeration cycle as air conditioning and dry dehumidifiers that use a dehumidifier. There is a problem that accompanies the rise.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and is an air conditioner capable of controlling temperature and humidity with lower energy consumption than conventional air conditioners. It is intended to provide means and an air conditioner.

[0007]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors have found that a heat exchange section using a Peltier module and a moisture absorbing member capable of desorbing and regenerating moisture are appropriately arranged. As a result, they have found that the above-mentioned problems can be solved, and have completed the present invention.

[0008] That is, the air conditioning means of the present invention is an air conditioning means provided with a heat exchanging part arranged on the upstream side of the air flow and a gas-permeable moisture absorbing member arranged on the downstream side thereof.
The heat exchange section has a heat absorbing section having a Peltier module and a heat radiating section, and the moisture absorbing member has a cooling / exhausting flow path formed downstream of the heat absorbing section of the heat exchanging section, and a downstream side of the heat radiating section. And a heating exhaust passage formed on the side.

Further, the air conditioner of the present invention comprises an air flow path having an intake port and an exhaust port, a heat exchange section housed between the intake port and the exhaust port of the air flow path, A gas-permeable moisture-absorbing member disposed in series with the heat exchange unit on the exhaust port side of the unit, wherein the heat exchange unit includes a heat-absorbing unit equipped with a Peltier module and a heat-radiating unit. An air flow path on the exhaust port side is partitioned from the heat absorbing section and the heat radiating section to form a cooling exhaust flow path and a heating exhaust flow path, respectively. , The exhaust port is provided at each end of the cooling exhaust channel and the heating exhaust channel, and the exhaust port of the cooling exhaust channel is connected to the air conditioning system. The exhaust port of the heating exhaust channel communicates with a system other than the air-conditioned system. And wherein the Rukoto.

Further, in a preferred embodiment of the air conditioner of the present invention, the space between the intake port and the heat exchange section is partitioned to form a cooling intake flow path and a heating intake flow path. And two intake ports are provided.

Further, in another preferred embodiment of the air conditioner of the present invention, the air flow path has a substantially cylindrical shape, and the moisture absorbing member has a substantially cylindrical shape, and the cylindrical moisture absorbing member has a cylindrical shape. It is characterized by being swingable or rotatable around the axis of the air flow path.

[0012]

According to the air conditioner of the present invention, the heat exchange section having the heat absorbing section and the heat radiating section corresponding to the Peltier module and the predetermined moisture absorbing member are arranged in series with the air flow of the air conditioning system. Therefore, there is no need to excessively cool the air flow to perform dehumidification, and it is possible to perform dehumidification / cooling with good energy efficiency.

Since the heat exchange section uses a Peltier module, efficient heat exchange can be performed with a small amount of supplied electric power, and the heat exchange section itself is also energy saving. Further, by using such a Peltier module, the size of the device can be reduced, and noise and vibration can be reduced. Also, by changing the direction of the current supplied to the Peltier module, the same device can be used for both dehumidification / cooling and humidification / heating.

Further, the moisture absorbing member is disposed over both the cooling exhaust passage and the heating exhaust passage corresponding to the heat absorbing portion and the heat radiating portion of the heat exchange portion. If it is configured to be movable or rotatable and displaceable, the portion that once faces the cooling exhaust flow path and has once absorbed moisture is then rotated and displaced to face the heating exhaust flow path, where heating is performed. By desorbing water, the moisture absorbing ability of the portion can be regenerated.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an air conditioner of the present invention will be described.
A specific embodiment will be described in detail with reference to the drawings.

FIG. 1 is a sectional view schematically showing an embodiment of the air conditioner of the present invention. In this figure, the air conditioner includes an air flow path 16 having an intake port and an exhaust port,
The heat exchange unit 12 includes a heat exchange unit 12 housed in the air flow path 16 and a gas permeable moisture absorbing member 13 arranged in series with the heat exchange unit 12. The air conditioning means of the invention is constituted. In the present embodiment, the air flow path 16 has two intake ports 1 and 2 and two exhaust ports 3.
The heat exchange section 12 is disposed between the exhaust port and the intake port, and the moisture absorbing member 13 is disposed on the exhaust port 3, 4 side of the heat exchange section 12.

The heat exchange section 12 includes a heat absorbing section 8 and a heat radiating section 1.
0 is sandwiched between the heat conducting part 9 and the heat conducting part 11.
6 is partitioned by a partition plate 18 to form an air passage 5 as an example of a cooling exhaust passage and an air passage 6 as an example of a heating exhaust passage.
However, an exhaust port 4 is provided at the end of the air passage 6. Further, in the present embodiment, the intake port side of the air flow path 16 is also partitioned by the partition plate 17, so that an air blowing path 5 'and a heating intake flow path 6', which are examples of a cooling intake flow path, are formed. The air inlet 1 and the air inlet 2 are respectively provided at the ends.

Further, in the present embodiment, the moisture absorbing member 13 is disposed immediately after the heat exchanging section 12, and the breathable moisture absorbing member 13 is disposed over both of the air passages 5 and 6, ie, concretely. Specifically, it has a cross-sectional shape that covers most of both cross-sections, and is installed so as to obstruct or obstruct the flow of air passing through both of them. It is formed to partition the side.

In the air conditioner of the present embodiment having the above-described configuration, the air passages 5 and 5 ′ are connected to the air intake port 1 from the indoor, which is an example of the air-conditioned system, or the outdoor, which is another example of the system. Intake air, heat exchange part 12 and moisture absorbing member 1
After adjusting the temperature and humidity by passing through the air outlet 3, the air is sent out from the exhaust port 3 to a room or another air conditioner. Here, the indoor / outdoor air may be taken in with the intake port fixed to one or the other, may be made switchable using a damper or the like, or may be made by mixing both. Is also good. In addition, an electric fan or the like is mainly used to take in air, but the installation position may be either the intake port 1 side or the exhaust port 5 side.

On the other hand, the air passages 6 and 6 ′ take in the air outside or inside the room through the air inlet 2, pass through the heat exchange section 12, heat the air, pass through the moisture absorbing member 13, and absorb the moisture contained in the moisture absorbing member 13. After desorbing and regenerating the water adsorbed on the material, the material is sent out of the room through the exhaust port 4.
As described above, an electric fan or the like is mainly used to take in air, and the installation position may be either the intake port 2 side or the exhaust port 6 side. Further, it is also possible to share a fan with the above-mentioned air passages 5 and 5 '.

In this embodiment, two intake ports are provided, i.e., the intake ports 1 and 2, but when air is taken in only from outside the room, it is possible to use one intake port.
Further, the partition plate 17 is not an indispensable member, and can be omitted. It is not necessary to provide the partition plate 17 particularly when there is one intake port. Furthermore, it is also possible to shorten or reduce the partition plate 17 so that the air passages 5 'and 6' are not completely separated but slightly communicate. Further, the partition plate 17 and the partition plate 18 can be formed integrally. Although two exhaust ports are also provided (exhaust ports 3 and 4), it is sufficient that the air passage 5 and the air passage 6 are separated. Needless to say, it may have a mouth.

The above-described air passages 5 and 5 'and air passage 6,
6 'may be formed by connecting, for example, resin pipes. However, considering the reduction in the number of parts and the ease of assembly, the heat exchange unit 12 and the moisture absorbing member 13 are housed to form an air passage. It is more preferable that the partitioning plate 18 or 17 is inserted into the housing 16 and divided into two parts to secure them. In this case, the cross-sectional shape of the housing 16 is preferably a polygon or a circle.

Next, the heat exchange section 12 cools the air passing through the air passage 5 by the heat conducting section 9 including the heat absorbing section 8 of the Peltier module 7 and the heat conducting section including the heat radiating section 10 of the Peltier module 7. The unit 11 heats the air passing through the air passage 6, and the cooled or heated air is sent to the moisture absorbing member 13. In this case, the moisture absorbing member 13
Is preferably rotatable or swingable in a direction perpendicular to the flow direction of the air flow, that is, around the axis of the air flow path 16.
The portion that was initially in contact with the airflow in the air passage 5 can be brought into contact with the airflow in the air passage 6 later, and the moisture absorbing member 13 can be regenerated as required. Is preferred.

In the present invention, the heat exchanging unit 12 is used
It is not intended only to cool the air sent to another air conditioner, but to pass through the air passage 5 and the air to be dehumidified so that the air dehumidification / humidification member can be efficiently regenerated. The function of adjusting the temperature of the regeneration air can be achieved. That is, generally, the higher the relative humidity, the higher the relative humidity of the moisture absorbing member. However, in the present air conditioner, the air to be dehumidified is cooled by the heat absorbing portion of the heat exchange portion 12 before the air to be dehumidified is introduced into the moisture absorbing member 13. As a result, the relative humidity increases, and as a result, the amount of absorbed moisture (dehumidification efficiency) can be improved. On the other hand, the regeneration air heated by the heat conducting unit 11 has a low relative humidity and is introduced into the moisture absorbing member 13. However, the portion of the moisture absorbing member 13 that comes into contact with the regeneration air is already used for dehumidification, and the moisture absorbing ability is reduced. If the part is
It is possible to regenerate the hygroscopic ability of such a portion.

Further, in the apparatus of the present invention, a Peltier module is used for the heat exchange section 12, so that cooling and heating can be efficiently performed with small input power. Such a Peltier module is not particularly limited, and one using various metal materials or semiconductor materials can be used. In particular, a P-type semiconductor element of a BiTe-based thermoelectric semiconductor and an N-type
The one formed by electrically joining the mold semiconductor element is preferable.
The shape and material of the heat conducting portion 9 and the heat conducting portion 11 are not particularly limited. However, in consideration of the heat conductivity to the passing air, a fin-shaped or honeycomb-shaped metal having high heat conductivity is used. More preferred.

Next, the moisture absorbing member 13 performs dehumidification in the air passage 5 and desorbs moisture adsorbed in the air passage 6 to be regenerated, and dehumidifies air passing through the air passage 5. It is for. As described above, the moisture absorbing member 13 is preferably swingable or rotatable around the axis of the air passage 16, and dehumidified while continuously moving between the air passages 5 and 6. It is preferable that the recording / reproduction can be repeated.

The shape of the moisture absorbing member 13 is not particularly limited, as long as it can face both the air passage 5 and the air passage 6 and can move both of them continuously with the both being cut off to a certain extent and having air permeability. . A honeycomb structure or mesh structure can be used so that air can pass through. However, in consideration of miniaturization of the device, simplification of the configuration, and ease of dehumidification / regeneration, a rotatable substantially cylindrical shape is used. It is more preferable that the top surface or the bottom surface of the cylinder is disposed so as to be substantially perpendicular to the air passage, so that the inside of the air passage 5 and the air passage 6 can be continuously moved. In this case, the rotating means is not particularly limited,
Use of change in own weight due to moisture absorption, direct drive with a motor, belt drive via a pulley, etc. are conceivable, but direct drive with a motor is more preferable in terms of ease of rotation speed adjustment and mechanical reliability. .

The material of the moisture absorbing member 13 is not particularly limited as long as it has a moisture absorbing ability, and silica gel, zeolite, sepiolite, activated alumina, lithium chloride, and an arbitrary mixture thereof can be used.
Further, these materials may be supported on a support such as aluminum or paper to constitute a moisture absorbing member, or the materials may be mixed with other materials as needed and directly extruded or used. Although it is good, it is more preferable to carry it on a support from the viewpoint of mechanical durability, weight, design freedom, and ease of manufacture.

In the air conditioner of the present invention, the heat exchange section 12 and the moisture absorbing member 13 as described above constitute one set (one unit), and a plurality of the air conditioners of the present invention constituted by such a combination are connected in series. It is preferable to arrange them in multiple stages. At this time, the number of stages can be set according to the intended air temperature and humidity, power consumption and dimensions of the apparatus, and there is no particular upper limit.
In addition, in the air conditioner of the present invention, at least one combination of the heat exchange unit 12 and the moisture absorbing member 13 is sufficient, but one or more heat exchange units 12 and / or one or more moisture absorbing members 13 are installed. For example, an arrangement of “heat exchange section-moisture absorbing member-heat exchange section” or “heat exchange section-moisture absorbing member-moisture absorbing member” is also possible.

With the multi-stage configuration as described above, the Peltier module can be operated under the condition of the highest coefficient of performance, and by changing the number of stages,
It is also possible to make a design change in response to a change in required performance. The driving means in the case of a multi-stage configuration is not particularly limited, and can be driven independently for each unit,
Of course, all units can be driven by a single drive source. Further, it goes without saying that control of the power supplied to the Peltier module 7 in each unit can be performed for each unit.

FIG. 2 shows another embodiment of the air conditioner of the present invention. Note that members that are substantially the same as those in the case of the air-conditioning apparatus illustrated in FIG. 1 are given the same reference numerals, and descriptions thereof are omitted. 2, in this air conditioner, the unit of the heat exchange unit 12 and the moisture absorbing member 13 has a two-stage configuration, the heating unit 15 is installed in the air passage 6 ′, and the other heat Although an exchange unit 14 is installed, other than this, it has the same configuration as the air conditioner of FIG.

In the apparatus of the present embodiment, the heat exchange section 14
Performs heat exchange between dehumidified air passing through the air passage 5 and regeneration air passing through the air passage 6, and can be appropriately used as an auxiliary in accordance with the characteristics of the heat exchange section 12 and the moisture absorbing member 13. The structure of the heat exchange unit 14 is not particularly limited. For example, the heat exchange unit 14 may have the same structure as the heat exchange unit 12, or may have a fin shape or a honeycomb shape having thermal conductivity.

On the other hand, the heating section 15 is used as an auxiliary heat source when the heat radiation of the heat exchange section 12 is insufficient. As the heating unit 15, a heater using waste heat of an engine or the like or a general electric heater can be used in a moving body such as an automobile, and a waste heat of various facilities is used in a general house, office or factory. , Heaters using natural energy such as sunlight or general electricity or gas can be used,
Although not particularly limited, it is more preferable to use natural energy such as waste heat or sunlight from the viewpoint of reducing energy consumption as the object of the present invention.

Although the structure and operation of the present invention have been described in detail above assuming that the present invention is used for cooling / dehumidifying, the direction of the current supplied to the Peltier module 7 is reversed,
, And the heat radiating section 10 on the heat absorbing side, the air conditioner of the present invention can also be used as a heating device having a humidifying function. In this case, the air conditioner is less than a general electric heater. Air can be heated with energy consumption. At this time, the driving of the moisture absorbing member 13 is stopped or the
It is of course possible to perform heating without performing humidification by stopping the ventilation in steps 6 and 6 ′. Furthermore, when the present invention functions as a heating device in this way, an auxiliary heat source similar to the heating unit 15 may be disposed in the air passage 5 or 5 ′ downstream of the moisture absorbing member 13.

Hereinafter, the present invention will be described in more detail with reference to the drawings by way of examples and comparative examples, but the present invention is not limited to these examples.
