(Embodiment 1)
Before concretely explaining the first embodiment of the present disclosure, the outline of the first embodiment will be described. The first embodiment relates to a ventilation system for performing air ventilation in a room where the temperature or humidity of the air is regulated by an air conditioner. The ventilation system includes an outside air passage that allows air to pass from the outside to the inside of the room, and an exhaust air passage that allows air to pass from the inside to the outside. At the indoor end of the outside air passage, an air supply port with a purification filter for purifying the air from the outside and then supplying air to the room is provided. An exhaust port for exhausting indoor air is provided at the indoor end of the exhaust air passage. In addition, an air conditioner will be installed on the wall surface of the room.

In such a situation, air whose temperature or humidity is adjusted by an air conditioner flows into the room, and air purified by an air supply port with a purification filter flows into the room. In order to make the indoor environment comfortable, it is preferable that the air whose temperature or humidity is regulated and the purified air are mixed. In order to efficiently mix these airs, in the present embodiment, an air supply port with a purification filter is arranged on the upper side of the air conditioner in the ceiling of the room. The air supply port with a purification filter blows air toward the air conditioner in the room. Therefore, the blown air is likely to be mixed with the air from the air conditioner.

Each of the embodiments described below shows a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, arrangement positions and connection forms of the components, steps (processes), order of steps, and the like shown in the following embodiments are examples, and the present disclosure is limited. It is not the purpose of doing it. Therefore, among the components in the following embodiments, the components not described in the independent claims indicating the highest level concept of the present disclosure are described as arbitrary components. Further, in each figure, the same reference numerals are given to substantially the same configurations, and duplicate explanations will be omitted or simplified.

FIG. 1 shows the configuration of the ventilation system 1000 of the first embodiment. The ventilation system 1000 includes an outside air passage 300, an exhaust air passage 302, a heat exchanger 310, a blower 320, an air supply port 330 with a purification filter, and an exhaust port 340. Of the configurations of the ventilation system 1000, at least one of the combination of the outside air passage 300, the blower 320, the air supply port 330 with a purification filter, the exhaust air passage 302, and the exhaust port 340 is called a ventilation system. May be good.

The ventilation system 1000 is installed in a facility such as a house and ventilates the air in the room 100 in the facility. A ceiling 110 is arranged on the upper surface of the room 100. A first wall surface 120 and a second wall surface 122 facing each other are arranged on the side surface of the room 100. A floor surface 130 is arranged on the lower surface of the room 100. An air conditioner 200 is installed on the first wall surface 120.

The air conditioner 200 has a cooling / heating function and regulates the temperature or humidity of the air in the room 100. Generally, the air conditioner 200 is composed of a combination of an indoor unit and an outdoor unit. However, here, the outdoor unit will be omitted, and the indoor unit will be described as the air conditioner 200. The air conditioner 200 includes an outlet 202. The air outlet 202 blows out conditioned air 500, which is air whose temperature or humidity is adjusted, toward the central portion of the room 100.

The outside of the facility having the indoor 100 is the outdoor 102, and the ducts connecting the outdoor 102 and the indoor 100 are the outside air passage 300 and the exhaust air passage 302. The outside air passage 300 and the exhaust air passage 302 are connected to the heat exchanger 310 in the middle portion. The heat exchanger 310 performs heat exchange between the air passing through the outside air passage 300 and the air passing through the exhaust air passage 302.

In the outside air passage 300, a blower 320 having a fan is provided on the indoor 100 side of the heat exchanger 310. The blower 320 causes air to flow from the outdoor 102 to the indoor 100 through the outside air passage 300 by rotating the fan. That is, the outside air of the outdoor 102 flows into the outdoor air passage 300 and heads toward the indoor 100.

An air supply port 330 with a purification filter is provided at the indoor end of the outside air passage 300. The air supply port 330 with a purification filter has a built-in purification filter (not shown). An example of a purification filter is a non-woven fabric, which has a function of capturing bacteria, molds, viruses, allergens and the like floating in the air. Therefore, the purification filter purifies the air flowing from the outdoor 102 toward the indoor 100 through the outdoor air passage 300 by the blower 320. The air supply port 330 with a purification filter causes the air purified by the purification filter to flow into the room 100 as the supply air 502.

An exhaust port 340 is provided at the indoor end of the exhaust air passage 302. The air existing in the room 100 flows into the exhaust air passage 302 from the exhaust port 340 by being pushed out by the conditioned air 500 and the supply air 502. The air that has flowed into the exhaust air passage 302 is exhausted to the outdoor 102 through the exhaust air passage 302. Therefore, it can be said that the exhaust port 340 exhausts the air in the room 100 to the outside 102. A blower may be provided in the exhaust air passage 302. By rotating the fan, the blower causes air to flow from the indoor 100 to the outdoor 102 through the exhaust air passage 302.

The air supply port 330 with a purification filter is arranged above the air conditioner 200 installed on the first wall surface 120 of the room 100 among the ceiling 110 of the room 100. More specifically, the air supply port 330 with a purification filter is arranged between the intermediate position 400 between the first wall surface 120 and the second wall surface 122 and the first wall surface 120 in the ceiling 110. That is, the air supply port 330 with a purification filter is arranged not separated from the first wall surface 120 on which the air conditioner 200 is installed from the intermediate position 400.

Further, when the distance between the air supply port 330 with a purification filter and the first wall surface 120 is set to the first distance 410 and the distance between the outlet 202 of the air conditioner 200 and the first wall surface 120 is set to the second distance 412, the first distance is set. One distance 410 is made longer than the second distance 412.

That is, the air supply port 330 with a purification filter is installed away from the first wall surface 120 and the outlet 202. The air supply port 330 with a purification filter arranged in this way executes air supply downward. As a result, the supply air 502 is likely to be mixed with the conditioned air 500 toward the central portion of the room 100.

Further, the exhaust port 340 is arranged between the intermediate position 400 between the first wall surface 120 and the second wall surface 122 and the second wall surface 122 in the ceiling 110. If the exhaust port 340 is arranged near the air supply port 330 with a purification filter, a short circuit will occur and the air supply port 502 will be exhausted immediately. On the other hand, by arranging the exhaust port 340 as shown in FIG. 1, the air in which the conditioned air 500 and the supply air 502 are mixed easily tends toward the central portion of the room 100.

The position where the outside air passage 300 is installed is not limited to the position shown in FIG. FIG. 2 shows another configuration of the ventilation system 1000. As in the past, the distance between the air supply port 330 with a purification filter and the first wall surface 120 is set to the first distance 410, and the distance between the outlet 202 of the air conditioner 200 and the first wall surface 120 is set to the second distance 412. If so, unlike FIG. 1, the first distance 410 is shorter than the second distance 412. That is, the air supply port 330 with a purification filter is arranged closer to the first wall surface 120 than the air outlet 202.

Here, the air supply port 330 with a purification filter is set with a wind direction toward an area intermediate between the first wall surface 120 and the second wall surface 122. Therefore, the air supply port 330 with a purification filter supplies air toward an intermediate region between the first wall surface 120 and the second wall surface 122, for example, the central portion of the room 100. The wind direction of the air supply port 330 with a purification filter is adjusted by, for example, a louver. Due to such a wind direction, the supply air 502 is less likely to hit the air conditioner 200 and heads toward the conditioned air 500.

According to the present embodiment, the air supply port 330 with a purification filter is arranged above the air conditioner 200 in the ceiling 110. Therefore, the conditioned air 500 and the supply air 502 can be efficiently mixed.

Further, the air supply port 330 with a purification filter is arranged above the air conditioner 200 in the ceiling 110. Therefore, the purified and clean supply air 502 can be quickly delivered to the person in the central portion of the room 100 by the conditioned air 500.

Further, the air supply port 330 with a purification filter is arranged between the intermediate position 400 of the first wall surface 120 and the second wall surface 122 and the first wall surface 120 in the ceiling 110. Therefore, the supply air 502 can be applied to the conditioned air 500.

Further, if the first distance 410 is made longer than the second distance 412, the air supply 502 can be less likely to be blocked by the air conditioner 200. Further, since the air supply 502 is not easily blocked by the air conditioner 200, the air supply 502 can be delivered to the central portion of the room 100. Further, since the first distance 410 is longer than the second distance 412, the warm air supply 502 is directly blown to the temperature sensor mounted near the upper surface of the air conditioner 200, and the temperature sensor accurately measures the temperature of the room 100. It is possible to prevent the detection from becoming undetectable.

Further, even if the first distance 410 is shorter than the second distance 412, the air supply port 330 with a purification filter supplies air toward an area intermediate between the first wall surface 120 and the first wall surface 120. Therefore, the air supply 502 can be less likely to be blocked by the air conditioner 200.

Further, the exhaust port 340 is arranged between the intermediate position 400 between the first wall surface 120 and the second wall surface 122 and the second wall surface 122 in the ceiling 110. Therefore, the occurrence of a short circuit can be suppressed. Further, since the occurrence of the short circuit is suppressed, the ventilation of the room 100 can be efficiently performed.

The outline of one aspect of this disclosure is as follows. The ventilation system of one aspect of the present disclosure is directed from the outdoor (102) to the indoor (100) through the outdoor air passage (300) connecting the outdoor (102) and the indoor (100) and the outdoor air passage (300).

Yes, the air supply port (330) is arranged between the intermediate position (400) of the first wall surface (120) and the second wall surface (122) and the first wall surface (120) in the ceiling (110). You may.

The distance between the air supply port (330) and the first wall surface (120) is the first distance (410), and the distance between the outlet (202) of the air conditioner (200) and the first wall surface (120) is the first. There are two distances (412), the first distance (410) being longer than the second distance (412).

The distance between the air supply port (330) and the first wall surface (120) is the first distance (410), and the distance between the outlet (202) of the air conditioner (200) and the first wall surface (120) is the first. There are two distances (412), the first distance (410) is shorter than the second distance (412), and the air supply port (330) is between the first wall surface (120) and the second wall surface (122). Air may be supplied toward the area.

The exhaust port (340) may be arranged between the intermediate position (400) of the first wall surface (120) and the second wall surface (122) and the second wall surface (122) in the ceiling (110). ..

(Embodiment 2)
Next, the second embodiment will be described. The second embodiment relates to a ventilation system 1000 that ventilates air into a room where the temperature or humidity of the air is regulated by the air conditioner 200, similarly to the first embodiment. The second embodiment is different from the first embodiment in the relative installation position of the air supply port 330 with a purification filter and the air conditioner 200. Specifically, in the first embodiment, the air conditioner 330 with a purification filter is arranged above the air conditioner 200, but in the second embodiment, the air conditioner 330 with a purification filter is the same as the air conditioner 200. Placed at height. Hereinafter, the differences from the first embodiment will be mainly described.

FIG. 3 shows the configuration of the ventilation system 1000 of the second embodiment. An air conditioner 200 is installed on the first wall surface 120, and an air supply port 330 with a purification filter is arranged on the second wall surface 122 facing the first wall surface 120. Here, the air conditioner 200 and the air supply port 330 with a purification filter are arranged at substantially the same height. Specifically, the height from the floor surface 130 where the air supply port 330 with a purification filter is arranged to the lower part of the air supply port 330 with a purification filter (the length of the first height 420 in FIG. 3; , "First height 420") and the height from the floor surface 130 on which the air conditioner 200 is installed to the lower part of the air conditioner 200 (the length of the second height 422 in FIG. 3; , "Second height 422") are substantially the same. Here, the abbreviation means almost including the range of error. For example, at least a part of the air supply port 330 with a purification filter and at least a part of the air conditioner 200 are arranged facing each other. The air supply port 330 with a purification filter arranged in this way executes air supply in the horizontal direction. As a result, the conditioned air 500 blown out from the facing surface and the supply air 502 are easily mixed in the central portion of the room 100.

Further, the exhaust port 340 is arranged between the first wall surface 120 and the second wall surface 122 in the ceiling 110. In particular, the exhaust port 340 is preferably arranged at an intermediate position 400 between the first wall surface 120 and the second wall surface 122 in the ceiling 110. This is because if the exhaust port 340 is arranged near the first wall surface 120, the conditioned air 500 from the air conditioner 200 will be exhausted in the short circuit.

According to the present embodiment, the air supply port 330 with a purification filter and the air conditioner 200 face each other and are arranged at substantially the same height. Therefore, the conditioned air 500 and the supply air 502 can be efficiently mixed.

Further, the air supply port 330 with a purification filter and the air conditioner 200 face each other and are arranged at substantially the same height. Therefore, the purified and clean supply air 502 can be quickly delivered to the person in the center of the room 100 by the conditioned air 500.

Further, at least a part of the air supply port 330 with a purification filter and at least a part of the air conditioner 200 face each other. Therefore, the conditioned air 500 and the supply air 502 can be efficiently mixed.

Further, the exhaust port 340 is arranged between the first wall surface 120 and the second wall surface 122 in the ceiling 110. Therefore, the ventilation of the room 100 can be efficiently performed.

The outline of one aspect of this disclosure is as follows. The ventilation system of one aspect of the present disclosure is directed from the outdoor (102) to the indoor (100) through the outdoor air passage (300) connecting the outdoor (102) and the indoor (100) and the outdoor air passage (300). A blower (320) that allows air to flow through the air passage (320), a purification filter (330) that purifies the air flowing from the outdoor (102) to the indoor (100) through the outside air passage (300) by the blower (320), and an outside air passage (320). It is provided at the indoor end of the room (300) and includes an air supply port (330) for supplying air purified by the purification filter (330) to the room (100). The air supply port (330) is arranged on the second wall surface (122) of the room (100) facing the first wall surface (120) of the room (100) in which the air conditioner (200) is installed. The first height (420) in which the (330) is arranged and the second height (422) in which the air conditioner (200) is installed are substantially the same.

At least a part of the air supply port (330) and at least a part of the air conditioner (200) may face each other.

The exhaust air passage (302) connecting the outdoor (102) and the indoor (100) and the indoor (100) air are provided at the indoor end of the exhaust air passage (302) and pass through the exhaust air passage (302). An exhaust port (340) for exhausting air to the outside (102) may be further provided. The exhaust port (340) may be arranged between the first wall surface (120) and the second wall surface (122) in the ceiling (110) of the room (100).

(Embodiment 3)
Next, the third embodiment will be described. Embodiment 3 relates to a ventilation system 1000 that performs air ventilation to a room where the temperature or humidity of the air is regulated by the air conditioner 200, as before. The third embodiment is different from the first embodiment and the second embodiment in the relative installation position of the air supply port 330 with a purification filter and the air conditioner 200. Specifically, in the first embodiment, the air conditioner 330 with a purification filter is arranged above the air conditioner 200, but in the third embodiment, the air conditioner 330 with a purification filter is below the air conditioner 200. Placed on the side. Hereinafter, the differences between the first embodiment and the second embodiment will be mainly described.

FIG. 4 shows the configuration of the ventilation system 1000 of the third embodiment. An air supply port 330 with a purification filter is also arranged on the first wall surface 120 in which the air conditioner 200 is installed. In particular, the air supply port 330 with a purification filter is arranged below the air conditioner 200. The air supply port 330 with a purification filter arranged in this way executes air supply in the horizontal direction. In order to explain the positional relationship between the air supply port 330 with a purification filter and the air conditioner 200 in more detail, FIGS. 5A, 5B and 5C are used here.

5A, 5B and 5C show the positional relationship between the air conditioner 200 and the air supply port 330 with a purification filter, and are front views of the first wall surface 120.

FIG. 5A shows the first example. The lower region 430 is a region formed on the lower side of the air conditioner 200, and the width thereof is within the width range of the air conditioner 200. The air supply port 330 with a purification filter is arranged in the lower region 430.

FIG. 5B shows a second example. The air conditioner 200 and the lower region 430 are the same as those in FIG. 5A. A part of the air supply port 330 with a purification filter is arranged in the lower region 430, and the rest of the air supply port 330 with a purification filter is arranged outside the lower region 430. From FIGS. 5A and 5B, it can be said that the air supply port 330 with a purification filter is arranged so as to overlap at least a part of the lower region 430.

FIG. 5C shows a third example. The air conditioner 200 and the lower region 430 are the same as those in FIG. 5A. The air supply port 330 with a purification filter is arranged outside the lower region 430.

The exhaust port 340 is arranged between the intermediate position 400 between the first wall surface 120 and the second wall surface 122 and the second wall surface 122 in the ceiling 110. That is, the exhaust port 340 is arranged away from the first wall surface 120 where the air conditioner 200 is installed, and away from the intermediate position 400. This is because if the exhaust port 340 is arranged near the air supply port 330 with a purification filter, a short circuit will occur and the air supply port 502 will be exhausted immediately. Further, if the exhaust port 340 is arranged near the first wall surface 120, the conditioned air 500 from the air conditioner 200 will be exhausted in the short circuit.

According to the present embodiment, the air supply port 330 with a purification filter is arranged below the air conditioner 200. Therefore, the air from the air conditioner and the air from the air supply port can be efficiently mixed.

Further, the air supply port 330 with a purification filter is arranged below the air conditioner 200. Therefore, the purified and clean supply air 502 can be quickly delivered to the person in the central portion of the room 100 by the conditioned air 500.

Further, the air conditioner 200 and the air supply port 330 with a purification filter are installed on the same first wall surface 120. Therefore, the construction can be simplified.

Further, the air supply port 330 with a purification filter is arranged below the air conditioner 200 while at least partially overlapping the air conditioner 200 within the width range of the air conditioner 200. Therefore, the conditioned air 500 and the supply air 502 can be quickly and easily delivered to the person in the central portion of the room 100.

Further, the air supply port 330 with a purification filter is arranged below the air conditioner 200 outside the width range of the air conditioner 200. Therefore, the degree of freedom of arrangement can be improved.

Further, the exhaust port 340 is arranged between the intermediate position 400 between the first wall surface 120 and the second wall surface 122 and the second wall surface 122 in the ceiling 110. Therefore, the ventilation of the room 100 can be efficiently performed.

The outline of one aspect of this disclosure is as follows. The ventilation system of one aspect of the present disclosure is directed from the outdoor (102) to the indoor (100) through the outdoor air passage (300) connecting the outdoor (102) and the indoor (100) and the outdoor air passage (300). A blower (320) that allows air to flow through the air passage (320), a purification filter (330) that purifies the air flowing from the outdoor (102) to the indoor (100) through the outside air passage (300) by the blower (320), and an outside air passage (320). It is provided at the indoor end of the room (300) and includes an air supply port (330) for supplying air purified by the purification filter (330) to the room (100). The air supply port (330) is arranged below the air conditioner (200) installed on the wall surface (120) of the room (100).

The air supply port (330) may be arranged under the air conditioner (200) while overlapping at least a part within the width range of the air conditioner (200).

The air supply port (330) may be arranged below the air conditioner (200) outside the width range of the air conditioner (200).

The present disclosure has been described above based on the embodiment. It will be appreciated by those skilled in the art that these embodiments are exemplary and that various variations of each of these components or combinations of processing processes are possible and that such modifications are also within the scope of the present disclosure. By the way.

In the air supply port 330 with a purification filter in the first to third embodiments, the purification filter and the air supply port are integrally configured. However, the present invention is not limited to this, and for example, the purification filter and the air supply port may be configured separately. According to this modification, the degree of freedom of configuration can be improved.

Further, although the outside air passage 300 and the exhaust air passage 302 are connected to the heat exchanger 310 in the middle portion, they do not have to go through the heat exchanger 310. Further, an air supply port 330 with a purification filter may be provided by making a hole in the wall surface or ceiling facing the outside. In this case, the outside air passage 300 is defined between the wall surface or ceiling facing the outside and the air supply port 330 with a purification filter. Similarly, an exhaust port 340 may be provided by making a hole in a wall surface or ceiling facing the outside. In this case, the exhaust air passage 302 is set between the wall surface or ceiling facing the outside and the exhaust port 340. The degree of freedom of configuration can also be improved by this modification.
