Japanese Unexamined Patent Publication No. 2012-201023

Recently, due to the effects of the spread of the new coronavirus infection, it is desired to realize a cleaner and more beautiful space than ever before.

The present invention has been made based on such circumstances, and an object of the present invention is to provide an air conditioning system that realizes a clean and beautiful space.

One aspect of the present invention is an air conditioning system based on a photocatalyst or an air catalyst, in which a ventilation port for sucking air into the room, a pipe fan for discharging the air in the room to the outside, and the ventilation. The air conditioner for circulating the air in the room is provided so that the air sucked from the mouth is discharged from the pipe fan, and the photocatalyst or the air catalyst is installed on at least the wall of the room.

According to the present invention, it is possible to provide an air conditioning system that realizes a clean and beautiful space.

It is a schematic block diagram which shows the air-conditioning system in a comparative example. It is a schematic block diagram which shows the air-conditioning system in Embodiment 1. FIG. It is explanatory drawing which showed the state that the business operator is constructing a photocatalyst. It is a schematic block diagram which shows the air-conditioning system in Embodiment 2. It is a schematic block diagram which shows the air-conditioning system in Embodiment 3. FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are merely examples. That is, the embodiments described below can be variously modified and implemented without departing from the spirit of the embodiment. In the drawings, the parts with the same reference numerals represent the same or similar parts unless otherwise specified.

[overview]
The business operator who provides the air conditioning system in the present invention (hereinafter, simply referred to as “business operator”) installs a photocatalyst in a room and proposes various facilities. Unlike conventional photocatalyst construction companies, we propose various equipment such as air conditioners and ventilation openings based on our own space design, in addition to photocatalyst construction. This provides a space that has a higher antiviral effect and deodorant effect than the conventional one, and has a reduced VOC.

[Comparison example]
FIG. 1 is a schematic configuration diagram showing an air conditioning system in a comparative example. Here, the state of the room 1 when the studio is viewed from the side is schematically drawn. For the sake of simplicity, windows and entrances are not drawn.

As shown in FIG. 1, it is assumed that the air conditioner (air conditioner) 21 is installed on the upper part of the wall 4 on the balcony 2 side and is connected to the outdoor unit 23 of the balcony 2 through the pipe 22. Further, it is assumed that the ventilation port 10 is provided on the wall 4 on the balcony 2 side.

A contractor who only installs a conventional photocatalyst generally installs the photocatalyst on the entire surface of the wall 4, which has the largest area as an interior member. Since the wind of the air conditioner 21 is mainly blown diagonally downward, the wind flows to the entrance side opposite the balcony 2. In such a case, when the door of the room is closed, even if the ventilation port 10 is provided on the wall 4 on the balcony 2 side, it is difficult for the air 3 to be replaced through the ventilation port 10.

That is, in the third type ventilation, the exhaust is forcibly performed by a machine (ventilation fan in a bathroom or kitchen, etc.), and the air supply is left to nature. Sufficient ventilation can be achieved if the room door is open, but in reality, the room door may be closed completely, in which case ventilation may be insufficient.

[Embodiment 1]
FIG. 2 is a schematic configuration diagram showing an air conditioning system according to the first embodiment. Since the basic structure of the studio is the same as that shown in FIG. 1, detailed description thereof will be omitted here.

In addition to the construction of the photocatalyst, the business operator proposes various equipment such as the air conditioner 21 and the ventilation port 11 based on the original space design. For example, it is assumed that the air conditioner 21 is provided with measures against dust and pollen. By combining such an air conditioner 21 and a photocatalyst and designing a space that maximizes these effects, it is possible to provide added value that other buildings do not have.

Specifically, as shown in FIG. 2, a ventilation port 11 for intake air and a pipe fan 12 for exhaust air are provided. The pipe fan 12 is a ventilation fan having a small fan built in a portion penetrating the outer wall of the exhaust pipe, and is provided in a portion (inside the room) where the required exhaust amount is small.

In this example, it is desirable to provide a ventilation port 11 on the upper part of the wall 4 on the balcony 2 side, a pipe fan 12 on the lower part of the wall 4 on the balcony 2 side, and an air conditioner 21 on the upper part of the wall 4 on the entrance side. As a result, in the side view, the ventilation port 11 and the pipe fan 12 are arranged substantially coaxially, and the pipe fan 12 is arranged at a position lower than the ventilation port 11. Further, the pipe fan 12 and the air conditioner 21 are arranged substantially diagonally, and the pipe fan 12 is arranged at a position lower than the air conditioner 21. By doing so, the air 3 in the room 1 can be circulated so that the air 3 sucked from the ventilation port 11 is discharged from the pipe fan 12 by the wind of the air conditioner 21. The weight of the volatile organic compound (VOC) 5 varies depending on the substance, but the wind of the air conditioner 21 makes it easy for the VOC 5 to be discharged from the pipe fan 12.

FIG. 3 is an explanatory diagram showing how the business operator is constructing the photocatalyst 6. Here, it is shown that the photocatalyst 6 is installed on the wall 4 of the room 1 by using the spray gun 7.

Photocatalyst 6 is a general term for substances that act to cause a chemical reaction with other substances by absorbing light. Typical photocatalytic active substances include titanium oxide and tungsten oxide. The photocatalyst 6 has functions such as removal of harmful substances, deodorization, sterilization, antibacterial, antiviral, and antifouling. For example, when titanium oxide is exposed to sunlight or ultraviolet rays of a fluorescent lamp, holes and electrons having strong oxidizing and reducing powers are formed. It is known that these holes and electrons convert water in the atmosphere into active oxygen and decompose organic substances and inorganic substances having high binding force.

The method of constructing the photocatalyst 6 is not limited to the method of using the spray gun 7, and other known construction methods may be used. Further, the range in which the photocatalyst 6 is installed is not limited to the wall 4 of the room 1, and may be installed on the ceiling, curtain, air conditioner 21, or the like.

As described above, according to the air-conditioning system according to the first embodiment, the air-conditioning system 21 with dust and pollen measures is combined with the photocatalyst, and the space is designed to maximize these effects to make other buildings. It is possible to provide added value that is not available in Japan. That is, it is possible to provide a space having a higher antiviral effect and deodorizing effect and reduced VOC as compared with the comparative example.

It is particularly effective to introduce such an air conditioning system at the time of new construction. In the case of a new construction, it is normal to equip the air conditioner 21 and the ventilation port 11 as standard, and in such a case, it is possible to provide a clean and beautiful space simply by adding the construction of a photocatalyst to the standard equipment of the building. Become.

Here, a set of air inlets / outlets 3 is provided by providing one ventilation port 11 for intake air and one pipe fan 12 for exhaust air, but the present invention is not limited thereto. For example, if the room 1 is originally provided with two ventilation ports 11, two pipe fans 12 may be added to provide two sets of air inlets and outlets.

Further, in the above description, although it is expressed as the ventilation port 11 for intake air, the role of the ventilation port 11 should not be interpreted in a limited manner. That is, the ventilation port 11 may mainly serve as an intake air, and the air 3 may be discharged to the outside from the ventilation port 11.

[Embodiment 2]
FIG. 4 is a schematic configuration diagram showing the air conditioning system according to the second embodiment. Hereinafter, only the differences between the air conditioning system and the first embodiment will be described.

In the second embodiment, as shown in FIG. 4, an air conditioner 21 is provided on the upper part of the wall 4 on the balcony 2 side, and a blower fan (air control device) 31 is provided in the middle of the wall 4 on the entrance side. It is desirable that the position of the blower fan 31 is lower than that of the air conditioner 21 and higher than that of the pipe fan 12. As a result, in the side view, the ventilation port 11 and the pipe fan 12 are arranged substantially coaxially, and the pipe fan 12 is arranged at a position lower than the ventilation port 11. Further, the pipe fan 12 and the blower fan 31 are arranged substantially diagonally, and the pipe fan 12 is arranged at a position lower than the blower fan 31. In this way, since the air of the air conditioner 21 is pushed back by the air of the blower fan 31, the air 3 of the room 1 can be circulated so that the air 3 sucked from the ventilation port 11 is discharged from the pipe fan 12. can.

As described above, according to the air conditioning system of the second embodiment, the same effect as that of the first embodiment can be obtained. Such second embodiment is particularly effective when it is difficult to change the position of the air conditioner 21.

[Embodiment 3]
FIG. 5 is a schematic configuration diagram showing the air conditioning system according to the third embodiment. Hereinafter, only the differences between the air conditioning system and the first and second embodiments will be described.

In the third embodiment, a relatively large room 1 such as an office or a store is assumed. Here, it is assumed that the ceiling-embedded air conditioner 41 is connected to the outdoor unit 43 through the pipe 42.

In general, entrance doors and windows are closed so that workers can work comfortably and efficiently in offices, and customers can spend comfortably in stores. In a large-scale building, the number of users increases, so that the dirty air 3 tends to accumulate in the room 1.

Therefore, as shown in FIG. 5, when the ventilation port 11 is installed on the ceiling, it is desirable to provide the pipe fan 12 under the wall 4 near the ventilation port 11. As a result, in the side view, the ventilation port 11 and the pipe fan 12 are arranged substantially coaxially, and the pipe fan 12 is arranged at a position lower than the ventilation port 11. Further, the pipe fan 12 and the air conditioner 41 are arranged substantially diagonally, and the pipe fan 12 is arranged at a position lower than the air conditioner 41. In this way, the air 3 in the room 1 can be circulated so that the air 3 sucked from the ventilation port 11 is discharged from the pipe fan 12 by the wind of the air conditioner 41.

As described above, according to the air conditioning system of the third embodiment, the same effect as that of the first and second embodiments can be obtained even in a relatively large room 1 such as an office or a store. As the building becomes larger, it is desirable to increase the number of sets of the ventilation port 11 and the pipe fan 12 to improve the ventilation.

Needless to say, the terms "substantially coaxial" and "substantially diagonally" as used herein include cases where they are not "coaxially" or "diagonally" in a strict sense. Since the shapes of buildings vary, the meanings of the terms "approximately coaxial" and "approximately diagonal" should be interpreted flexibly.

[Modification example]
In the above description, the photocatalyst is to be installed, but an air catalyst may be installed instead of the photocatalyst. An air catalyst is a catalyst that works by utilizing water and oxygen in the air. In an environment where light is difficult to reach, it is effective to install an air catalyst instead of a photocatalyst.

Further, although it is assumed that the air conditioners 21 and 41 are provided with dust countermeasures and pollen countermeasures, the ventilation port 11 and the blower fan 31 may also be provided with dust countermeasures and pollen countermeasures. This makes it possible to more effectively remove dust and pollen that are likely to cause allergies.

[Characteristic configuration of the present invention and its effect]
As described above, the air conditioning system in the present invention is an air conditioning system based on a photocatalyst or an air catalyst, and has a ventilation port 11 for sucking air 3 into the room 1 and air 3 in the room 1 is discharged to the outside. And an air control device (for example, air conditioners 21 and 41 and a blower fan 31) that circulates the air 3 in the room 1 so that the air 3 sucked from the ventilation port 11 is discharged from the pipe fan 12. A photocatalyst or an air catalyst is installed on at least the wall 4 of the room 1. As a result, it is possible to provide an air conditioning system that realizes a clean and beautiful space by producing a large effect by the effect of the photocatalyst or the air catalyst and the circulation of the air 3.

Here, it is desirable that the ventilation port 11 and the pipe fan 12 are arranged substantially coaxially, and the pipe fan 12 is arranged at a position lower than the ventilation port 11. As a result, the air 3 in the room 1 can be efficiently circulated.

Further, it is desirable that the pipe fan 12 and the air adjusting device are arranged substantially diagonally, and the pipe fan 12 is arranged at a position lower than the air adjusting device. As a result, the air 3 in the room 1 can be efficiently circulated.

In addition, it is desirable that the air conditioner is provided with measures against dust or pollen. This makes it possible to more effectively remove dust and pollen that are likely to cause allergies.
