Description

[Technical Field]

[0001] The present disclosure relates to air conditioning systems. [Background technology]

[0002] The following Patent Document 1 describes a flooring material that includes an electromagnetic attraction part that attracts electrically charged floating matter, and a surface material that is layered on top of the electromagnetic attraction part. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-130394 Summary of the Invention [Problem to be solved by the invention]

[0004] The technology of Patent Document 1 can adsorb suspended particles such as dust and pollen. However, living spaces have places where dust tends to collect and places where it does not, and such flooring materials may not necessarily be able to adsorb dust effectively depending on the installation location.

[0005] In consideration of the above, the present disclosure aims to provide an air conditioning system that can adsorb dust in a living space. [Means for solving the problem]

[0006] The air conditioning system of the first aspect includes an air conditioning device that draws air from a living space through an air intake port, an air supply duct that has one end connected to the air conditioning device and the other end having an air outlet that opens into a room, and a charging plate that is provided in the living space between the air outlet and the air intake port and can be charged with static electricity.

[0007] In the air conditioning system of the first aspect, a statically charged plate is provided between an air outlet for conditioned air and an air inlet for drawing air from the living space. That is, the statically charged plate is provided in the air circulation path in the living space.

[0008] This makes it easier to attract dust in the living space and prevent it from scattering, compared to when there is no charged plate or when the charged plate is provided somewhere other than the air circulation path.In addition, because the dust gathers on the charged plate, it is easier to clean.

[0009] The air conditioning system of the second aspect is the air conditioning system of the first aspect, in which the air conditioning device is a whole-building air conditioning device, the air supply duct is provided for each of a plurality of rooms, and a ventilation opening is provided at the bottom of the wall or fixture separating each room from the living space adjacent to the room, and the charged plate is installed on the floor surface below the ventilation opening.

[0010] In the air conditioning system of the second aspect, the air conditioning device is a central air conditioning device and blows conditioned air into multiple rooms, which allows it to adsorb dust over a wider range than when the air conditioning device is not a central air conditioning device.

[0011] The charged plates are installed on the floor below the ventilation openings in each room. This allows them to adsorb dust at the location where the air in each room gathers along the air circulation path in the living space. This provides a higher dust scattering suppression effect than when the charged plates are installed in locations other than on the floor below the ventilation openings in each room.

[0012] The air conditioning system of the third aspect is the air conditioning system of the first aspect, further comprising a machine room in which the air conditioning unit is installed, and a ventilation opening at the bottom of a wall or fixture separating the machine room from the living space adjacent to the machine room, and the charged plate is installed on the floor surface below the ventilation opening.

[0013] In the air conditioning system of the third aspect, the charged plate is installed on the floor below the ventilation openings in the machine room where the air conditioning unit is installed. This allows dust to be adsorbed in the area where the air from the entire living space gathers in the air circulation path in the living space. This provides a higher dust scattering suppression effect than when the charged plate is installed in a location other than the floor below the ventilation openings in the machine room.

[0014] In addition, the air conditioning system of the third aspect may be the air conditioning system of the first or second aspect, further comprising a machine room in which the air conditioning unit is installed, and a ventilation opening at the bottom of a wall or fixture separating the machine room from the living space adjacent to the machine room, and the charged plate may be installed on the floor surface below the ventilation opening.

[0015] The air conditioning system of the fourth aspect is the air conditioning system of the first aspect, wherein the air conditioning unit is installed inside the ceiling, the air inlet opens into the ceiling, and the charged plate is installed on the ceiling surface around the air inlet.

[0016] In the air conditioning system of the fourth aspect, the charged plate is installed on the ceiling surface around the air intake of the air conditioner installed in the ceiling. Therefore, dust can be adsorbed in the area where air from the entire living space gathers in the air circulation path in the living space. This provides a higher dust scattering suppression effect than when the charged plate is installed in a location other than the ceiling surface around the air intake.

[0017] In addition, an air conditioning system of a fourth aspect may be the air conditioning system of any one of the first to third aspects, in which the air conditioning unit is installed in a ceiling, the air inlet opens into the ceiling, and the charged plate is installed on the ceiling surface around the air inlet.

[0018] The air conditioning system of a fifth aspect is the air conditioning system of the first aspect, further comprising a power supply device that charges the charged plate by applying a voltage to the charged plate, and the power supply device applies the voltage when the air conditioning system is operating.

[0019] In the air conditioning system of the fifth aspect, by applying a voltage when the air conditioner is operating, dust is attracted to the charged plate when there is air flow in the living space. Therefore, the dust attracting effect is higher than when the charged plate is charged with static electricity when the air conditioner is not operating, i.e., when there is little air flow. Furthermore, since no voltage is applied to the charged plate when the air conditioner is not operating, the energy saving effect is high.

[0020] In addition, an air conditioning system of a fifth aspect may be an air conditioning system of any one of the first to fourth aspects, further comprising a power supply device that charges the charged plate by applying a voltage to the charged plate, and the power supply device may apply the voltage when the air conditioning system is operating. [Effects of the Invention]

[0021] According to the present disclosure, dust in the living space can be adsorbed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, an air conditioning system according to an embodiment of the present disclosure will be described with reference to the drawings. Components indicated by the same reference numerals in the various drawings are the same components. However, unless otherwise specified in the specification, each component is not limited to one, and may be present in multiple numbers.

[0024] Furthermore, descriptions of overlapping configurations and symbols in each drawing may be omitted. Note that the present disclosure is not limited to the following embodiments, and may be implemented by making appropriate modifications, such as omitting configurations or replacing them with different configurations, within the scope of the purpose of the present disclosure.

[0025] <Air conditioning system> As shown in FIG. 1, an air conditioning system 80 according to an embodiment of the present disclosure is a whole-building air conditioning system applied to a building 70, and is configured to include an air conditioning unit 20 (air conditioning units 20A and 20B) and a charged plate 30.

[0026] (Air conditioner) Air conditioners 20 (air conditioners 20A and 20B) are air conditioning equipment installed on the first and second floors of building 70, respectively, and are equipped with an indoor unit 22, an outdoor unit 24, and a remote control (not shown). Air conditioner 20 can air-condition multiple rooms with one indoor unit 22 and one outdoor unit 24. Indoor unit 22 and outdoor unit 24 are connected by a refrigerant pipe (not shown).

[0027] In this embodiment, the air conditioner 20B on the second floor is installed in the ceiling (attic space 74A) and conditions the rooms 72A and 72B on the second floor. The air conditioner 20A on the first floor is installed in the machine room 74B and conditions the rooms 72C, 72D, 72E, and 72F on the first floor. In the following description, the rooms 72A to 72F may be collectively referred to as rooms 72.

[0028] In addition, in this embodiment, the first and second floors of the building 70 are air-conditioned by two air conditioners 20A and 20B, but the first and second floors of the building 70 may also be air-conditioned by a single air conditioner. In this specification, these air conditioners are collectively referred to as a central air conditioner.

[0029] One end of each of a plurality of supply air ducts 50 is connected to the indoor unit 22. The air outlets 50A at the other end of the supply air duct 50 connected to the indoor unit 22 of the air conditioner 20B on the second floor open to each of a plurality of rooms 72A and 72B. The air outlets 50A at the other end of the supply air duct 50 connected to the indoor unit 22 of the air conditioner 20A on the first floor open to each of a plurality of rooms 72C, 72D, 72E, and 72F.

[0030] The air supply duct 50 may be connected directly to the indoor unit 22, as in the case of the air conditioner 20B on the second floor, or may be connected to the indoor unit 22 via a chamber 54 or the like, as in the case of the air conditioner 20A on the first floor. In this manner, the term "air supply duct the one end of which is connected to an air conditioner" in this disclosure also includes an air supply duct that is converged and branched by a chamber 54 or the like.

[0031] As in the air conditioner 20B on the second floor, a return air duct 52 may be connected to the indoor unit 22. The return air duct 52 is a duct that returns air drawn in from an air inlet 52A in any part of the living space of the building 70 (for example, the ceiling) to the indoor unit 22.

[0032] Note that, like the air conditioner 20A on the first floor, the return air duct 52 may not be provided, and the indoor unit 22 may draw air directly from the living space of the building 70 through an air inlet (not shown). In this way, the air conditioner 20 in the present disclosure draws air from the living space through the air inlet.

[0033] (ventilation opening) A ventilation opening 76 is provided at the bottom of the wall W or fitting D (see Figure 2) that separates each room 72 from the living space adjacent to the room 72. The "living space" includes any of the rooms 72 and various spaces such as corridors that are not classified as rooms 72.

[0034] For example, as shown in Fig. 2, a louver 76A or the like can be provided at a ventilation opening 76, which is an opening formed in a wall W. On the other hand, the gap between a fitting D and a floor F (a so-called undercut) may also be used as the ventilation opening 76.

[0035] In addition, sound-absorbing panels 26 that absorb the driving noise of the air conditioner 20A are installed in the machine room 74B on the first floor where the air conditioner 20A is installed. The sound-absorbing panels 26 are preferably installed facing the ventilation openings 76. In Fig. 2, the sound-absorbing panels 26 are arranged only on the door frame D side, but the sound-absorbing panels 26 can also be installed on the wall W side.

[0036] (Air circulation path) 1, the conditioned air blown out from the air outlet 50A passes through the room 72 and other living spaces before returning to the air conditioner 20. In each room 72, the air flows from the air outlet 50A through the indoor space to the ventilation opening 76 on the indoor unit 22 side (or on the air inlet 52A side).

[0037] (Charged plate) The charged plate 30 is provided in the living space of the building 70 between the air outlet 50A and the air inlet (the air inlet 52A or the air inlet of the air conditioner 20A), and is a plate material that can be charged with static electricity.

[0038] The above-mentioned "between the air outlet 50A and the air inlet" refers to a location on the air circulation path, and as an example, is the floor surface below the ventilation opening 76. The ventilation openings 76 in which the charging plate 30 is provided include the ventilation openings 76 of each chamber 72 and the ventilation opening 76 of the machine chamber 74B. Note that the ventilation openings 76 of each chamber 72 are provided downstream of the path along which the air circulates as viewed from the air outlet 50A.

[0039] Moreover, "below the ventilation opening 76" refers to a portion within a range of approximately 50 cm from the louver 76A shown in Fig. 2, for example. Also, it refers to a portion within a range of approximately 50 cm from the fitting D, including directly below the fitting D.

[0040] As another example, "between air outlet 50A and air inlet" refers to the ceiling surface around air inlet 52A that opens into the ceiling. "Around air inlet 52A" refers to the area within approximately 50 cm of air inlet 52A.

[0041] As shown in Fig. 3(A), the charged plate 30 can be formed in the same shape as the floor material 40 and installed on the floor by partially replacing the floor material 40. Alternatively, the charged plate 30 may be installed on the floor by being attached to the surface of the floor material 40, as shown in Fig. 3(B). Furthermore, the charged plate 30 may be installed on the floor by being placed in a cutout portion of the base material 42 that fixes the floor material 40, as shown in Fig. 3(C).

[0042] 3 shows an example in which flooring material is used as floor material 40, but tiles, carpet, etc. may also be used as floor material 40. The material of base material 42 can be selected appropriately depending on the material of floor material 40, such as structural plywood or particle board.

[0043] The size of the charged plate 30 is not particularly limited, but it is formed into a long shape with a width of, for example, 30 cm or less, preferably 20 cm or less, so that dust adsorbed by static electricity can be easily removed using a vacuum cleaner or the like.

[0044] The material for forming the charged plate 30 may be a nonwoven fabric or a polymer material (for example, a fluorine-based polymer, polyethylene, or polypropylene) that has been subjected to electret processing.

[0045] Alternatively, the charged plate 30 may be formed using a conductor such as steel, and a voltage may be applied to the charged plate 30 by a power supply device (not shown). Such a power supply device may be driven in conjunction with the air conditioner 20. For example, the power supply device may apply a voltage to the charged plate 30 while the air conditioner 20 is operating.

[0046] <effect> In an air conditioning system 80 according to an embodiment of the present disclosure, a statically charged plate 30 is provided between an air outlet 50A for conditioned air and an air inlet (inlet 52A) for drawing in air from the living space. That is, the statically charged plate 30 is provided in the air circulation path in the living space.

[0047] This makes it easier to attract dust in the living space and prevents the dust from scattering, compared to when there is no charged plate 30 or when the charged plate 30 is provided somewhere other than the air circulation path. Also, because the dust is collected on the charged plate 30, cleaning is easier.

[0048] Furthermore, in the air conditioning system 80, the air conditioner 20 is a central air conditioner, and the conditioned air is blown out to multiple rooms 72. This allows for dust adsorption over a wider range than when the air conditioner is not a central air conditioner.

[0049] Furthermore, the charged plate 30 is installed on the floor surface below the ventilation openings 76 provided in each room 72. Therefore, dust can be adsorbed at the location where air gathers within each room 72 in the air circulation path in the living space. This provides a higher effect of suppressing dust scattering compared to when the charged plate 30 is installed in a location other than on the floor surface below the ventilation openings 76 of each room 72.

[0050] Furthermore, in the air conditioning system 80, the charged plate 30 is also installed on the floor below the ventilation opening 76 provided in the machine room 74B in which the air conditioner 20A is installed. Therefore, dust can be adsorbed in a location in the air circulation path in the living space where air from the entire living space gathers. This provides a higher dust scattering suppression effect than when the charged plate 30 is installed in a location other than the floor below the ventilation opening of the machine room 74B.

[0051] Furthermore, in air conditioning system 80, charged plate 30 is installed on the ceiling surface around air inlet 52A of air conditioner 20B installed inside the ceiling (attic space 74A). This allows dust to be adsorbed in a location where air from the entire living space gathers in the air circulation path in the living space. This provides a higher dust scattering suppression effect than when a charged plate is installed in a location other than the ceiling surface around air inlet 52A.

[0052] Furthermore, in the air conditioning system 80, a voltage can be applied when the air conditioner 20 is operating. This allows dust to be attracted to the charged plate 30 when there is air flow in the living space. This provides a higher dust attraction effect than when the charged plate 30 is charged with static electricity when the air conditioner 20 is not operating, i.e., when there is little air flow. Furthermore, because no voltage is applied to the charged plate 30 when the air conditioner 20 is not operating, this provides a high energy-saving effect.

[0053] In the above embodiment, the charged plates 30 are installed at all positions on the ceiling surface around the ventilation openings 76 in each chamber 72, the ventilation openings 76 in the machine chamber 74B, and the suction opening 52A, but the embodiments of the present disclosure are not limited to this.

[0054] For example, the charged plate 30 may be installed at any position among the ventilation openings 76 in each room 72, the ventilation openings 76 in the machine room 74B, and the ceiling surface around the intake port 52A. Even in this embodiment, dust in the living space is more easily attracted than when the charged plate is installed somewhere other than the air circulation path. [Explanation of symbols]
