Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning structure for an underground storage.

[0002]

2. Description of the Related Art Generally, an underground space such as an underground storage is
It is said that the temperature and humidity are relatively stable. However, after the cold, dry outside air invades in the winter season, or the warm, high-humidity outside air in the rainy season enters, dew condensation occurs on the wall surface.

Therefore, conventionally, such an underground storage has been equipped with a dehumidifier and an air conditioner which are usually commercially available.

Further, as such a dehumidifier exclusively for the underground, a fan is used to create a flow of air in a moisture absorbing / releasing material mounted near the ceiling surface to absorb moisture, and then the moisture absorbing / releasing material is heated. It is known that moisture absorbed by a moisture absorbing / releasing material is released to the outside as steam using a fan.

[0005]

However, among the above-mentioned conventional dehumidifiers, the commercially available dehumidifier is not premised to be used in a narrow space such as an underground storage, and therefore has a capability. Inconveniently, it is too large. Further, since it is used underground, it is necessary to add a function of collecting the collected condensed water in a tank or draining it by pumping it to the ground, which causes a problem that natural drainage cannot be performed. Furthermore, since such a function must be added, the device becomes large, and when it is used in a narrow space such as an underground storage, there is an inconvenience that it takes up a lot of space for installation.

Further, since the dew condensation on the wall surface is likely to occur on the peripheral edge of the hatch where the outside air enters, in order to remove this dew condensation, it is dried along the peripheral wall of the hatch peripheral edge where the dew condensation occurs, that is, the peripheral edge of the ceiling surface. It is desirable to blow air. However, in the case of the above-described conventional dehumidifier, since it cannot be installed near the limited ceiling surface of the underground storage, it is not possible to effectively remove the condensation formed on the wall surface. Therefore, even if the relative humidity in the underground storage is stable and the dehumidifier is automatically stopped, the dew condensation still occurs on the wall surface.

Further, in the case of a dehumidifier using a moisture absorbing / releasing material,
Since the operation of absorbing moisture and the operation of releasing moisture must be repeated alternately, there arises a disadvantage that the dehumidifying efficiency is poor.

The present invention has been made in view of the above circumstances, and provides an air conditioning structure suitable for an underground storage that can surely remove the dew condensation that has occurred on the wall surface and spontaneously drain the collected dew condensation water. It is intended to be provided.

[0009]

In order to solve the above-mentioned problems, the air conditioning structure for an underground storage according to the present invention is thinned by using a heat exchange element whose one surface has a low temperature and whose other surface has a high temperature. The machine body of the machine is installed on the ceiling surface of the underground storage, and the dehumidification wastewater generated from this equipment is allowed to naturally flow down to the gutter adjacent to the underground storage.
The outlet of the dry air from the apparatus main body is set so that the dry air circulates along the wall surfaces such as the side wall surface and the floor surface.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show a state in which the air conditioner 1 is installed in the underground storage 10, and FIG. 3 shows the air conditioner 1 installed in the underground storage 10.

That is, in the air conditioning structure of the underground storage 10, the apparatus body 2 of the air conditioner 1 is arranged on the ceiling surface of the underground storage 10, and the dehumidifying waste water generated from the apparatus body 2 is
While letting it naturally flow down to the gutter 8 adjacent to the underground storage 10, the dry air blown out from the device body 2 is circulated along the wall surfaces of the underground storage 10, such as the ceiling surface, side wall surface and floor surface. Has been done.

The underground storage 10 is a rainwater utilization tank 10a.
And is configured integrally. In addition, an electric water heater 10b is provided in the underground storage 10. The electric water heater 10b is provided with a hot water supply pipe 10c, a water supply pipe 10d, an overflow pipe 10e, and an electric wiring pipe 10f, which are extended from the underground storage 10 to the outside. Of these, the overflow pipe 10e is arranged so as to naturally flow down to the adjacent side groove 8 with a downward slope.

The air conditioner 1 comprises an apparatus body 2, a heat exchange element 3, a cooling plate 4, a heat radiating plate 5, a fan 6, and a control device 7.

The device body 2 is a hatch 1 of an underground storage 10.
It is attached to the ceiling surface adjacent to 0g. In this mounted state, the apparatus main body 2 is formed thin so that the dehumidification drainage generated from the apparatus main body 2 can be naturally flowed down to the gutter 8 adjacent to the underground storage 10 to ensure a height difference. . Further, an opening 23 is provided near one side surface 22 of the bottom surface 21 of the apparatus body 2, and a drain port 25 near the other side surface 24.
Is provided. Then, a drainage channel 25a communicating with the overflow pipe 10e of the electric water heater 10b at a downward slope is extended to the drainage port 25, and the dehumidification drainage is discharged from the drainage channel 25a to the side groove 8 via the overflow pipe 10e. It is designed to be drained by natural flow. Further, in the opening 23, a partition 26 having a mountain-shaped cross section having an upslope and a downslope is provided, and a condensation passage 27 and a heating passage 28 are formed in the apparatus main body 2. Further, a ventilation hole 29 is provided on the other side surface 24 of the apparatus body 2.

As the heat exchange element 3, a thermo module is used, which is formed so that one surface has a low temperature and the other surface has a high temperature when a voltage is applied. The heat exchange element 3 is attached to the attachment hole 20 provided in the descending slope portion of the partition 26 of the apparatus main body 2 so that the low temperature surface is located in the condensation passage 27 and the high temperature surface is located in the heating passage 28. . Then, the cold plate 4 and the heat radiating plate 5 are attached to the low-temperature surface and the high-temperature surface, respectively, via an electrical insulator such as silicon grease. As a result, the condensation passage 27 in the device body 2 is
The heating passage 28 is cooled by the cooling from the cooling plate 4, and the heating path 28 is heated by the radiation from the radiation plate 5.

The fan 6 is provided on one side surface 22 of the apparatus main body 2. Then, by the operation of the fan 6, a negative pressure is generated in the apparatus main body 2, and the negative pressure causes the opening 23
To form a flow of air passing through the condensation passage 27 and the heating passage 28 and a flow of air passing through the ventilation hole 29 and the heating passage 28.

Therefore, the air sucked from the opening 23 is cooled in the condensing passage 27 to generate dew condensation water on the surface of the cooling plate 4. At this time, since the cooling plate 4 is located at the descending slope portion of the partition plate 26, the air from the opening 23 efficiently hits the cooling plate 4 to be cooled. In addition, since the water has a downward slope, the dew condensation water generated by cooling becomes a drop and is easy to drop. Further, since the negative pressure generated by the fan 6 is divided into two by the flow of air from the opening 23 and the flow of air from the ventilation hole 29, the air flowing through the condensation passage 27 from the opening 23 is separated. The flow can be a gentle flow suitable for producing condensation. This air flow can be adjusted by the degree of opening of the vent hole 29. The air thus cooled in the condensation passage 27 is mixed with the air from the ventilation hole 29, passes through the heating passage 28, and is heated by the heat radiation from the heat dissipation plate 5 to become dry air. As described above, when the heat exchange element 3 is used, the air that has been cooled and condensed on one surface can be heated on the other surface to be dried air. Therefore, the heat exchange element 3 is sandwiched between the condensation passage 27 and the heating passage. 28, it is possible to configure the apparatus main body 2 formed thin.

The control device 7 comprises a humidity sensor 71 and a temperature sensor 72, and controls the fan 3 and the heat exchange element 4 in accordance with the humidity sensor 71 and the temperature sensor 72. At this time, if the number of rotations of the fan 3 is controlled and changed, there is a concern that the flow of air flowing through the condensation passage 27 may deviate from a gentle flow suitable for causing dew condensation. Is preferably limited to on / off control. In addition, the heat exchange element 4
Is set to generate a temperature difference in a low temperature region such as 10 ° C. on the low temperature side and 60 ° C. on the high temperature side, or 30 ° C. on the low temperature side,
The temperature of the dry air blown from the fan 6 can be lowered or raised by setting the temperature difference in a high temperature region such as 80 ° C. on the high temperature side. Therefore, the temperature control is performed by changing the setting of this temperature range by the temperature sensor 72 provided in the control device 7. In the case of this air conditioner 1, the temperature control is slightly less than the dehumidifying ability, but as the air conditioner 1 of the underground storage 10 in which the temperature is stable and the condensation on the wall surface is difficult, It will be suitable. Since the control device 7 is provided with the humidity sensor 71 and the temperature sensor 72, the dry air blown out from the fan 6 is arranged at the front position where the dry air blows into the underground storage 10 and returns to the ventilation hole 29. It is preferable.

The air conditioner 1 constructed in this way
Is a ventilation hole in which the dry air discharged from the fan 6 circulates from the ceiling surface of the underground storage 10 along the side wall surface and the floor surface in a state where the apparatus body 2 is attached to the ceiling surface of the underground storage 10. The blowout direction of the fan 6 is set so that it can easily return to 29. In the case of the present embodiment, both sides of the ceiling surface of the underground storage 10 are obliquely cut out, so that the air circulation as described above is easily obtained. In this way, the underground storage 10
In the case of, the humidity and temperature are relatively stable, and the hatch 10
Since it is the current situation that dew forms on the wall surface due to the outside air entering from g, the dry air from the air conditioner 1 is efficiently dispersed by being circulated along the wall surface without being dispersed in the underground storage 10. Condensation can be removed. Alternatively, the direction of the dry air blown out from the fan 6 may be changed each time by attaching the apparatus body 2 to the ceiling surface in a state in which the direction can be changed automatically or manually. In this case, the dry air from the fan 6 can be directly blown toward the condensation formed on the wall surface, and the condensation can be removed more positively.

[0021]

As described above, according to the present invention, the air conditioner apparatus main body which is thinned by using the heat exchange element whose one surface is low temperature and whose other surface is high temperature is used as the ceiling surface of the underground storage. Since the dehumidifying wastewater from the equipment body flows down naturally, it is possible to drain the dehumidifying wastewater generated from the equipment body to the outside without installing a pump-up function or a drain tank. it can.

Further, the apparatus body of the air conditioner is installed on the ceiling surface as described above, and the dry air from the apparatus body is so arranged that the dry air circulates along the wall surfaces such as the ceiling surface, the side wall surface and the floor surface. By setting the air outlet of No. 3, dry air can be positively blown to the periphery of the opening of the underground storage where dew condensation is likely to occur, that is, near the ceiling surface. Therefore, even if the relative humidity in the underground storage is stable, it is possible to prevent condensation on the wall surface.
