  Hereinafter, in the building 1 of the present embodiment, the lower floor space 2, the upper floor space 3, the first communication passage 4 and the second communication passage 5 can be implemented using the first air conditioner 6 and the second air conditioner 7. A concrete example of air circulation of

  FIG. 5: is a figure which shows an example of the circulation of air performed using the 1st air conditioner 6 and the 2nd air conditioner 7 in the building 1 of this embodiment. FIG. 5 shows the same cross section as FIG. 3, and the circulation path of the wind by the first air conditioner 6 and the second air conditioner 7 is shown by the arrows in the figure.

  The first air conditioner 6 of the present embodiment is attached to the first facing wall surface 8 a on the first floor as a hierarchy of the lower floor space 2, and winds toward the second communication passage 5 (hereinafter referred to as “first blowout” Can be supplied). Specifically, the first blowoff flow supplied from the first air conditioner 6 of the present embodiment is supplied to the second communication passage 5 through the first communication passage 4 and the lower floor space 2 on the first floor. . And the 1st blowing flow supplied to the 2nd communicating path 5 blows in on the 2nd floor as a hierarchy of upper floor space 3 along the 2nd opposed wall surface 12a. That is, the first air conditioner 6 of the present embodiment supplies wind from the first floor as the hierarchy of the lower floor space 2 to the second floor as the hierarchy of the upper floor space 3 along the second facing wall surface 12a. be able to.

  The second air conditioner 7 of the present embodiment is attached to the second facing wall surface 12 a on the second floor as a hierarchy of the upper floor space 3, and winds toward the first communication passage 4 (hereinafter referred to as “second blowout Can be supplied). Specifically, the second blowoff flow supplied from the second air conditioner 7 of the present embodiment is supplied to the first communication passage 4 through the second communication passage 5 and the upper floor space 3 in the second floor. . And the 2nd blowing flow supplied to the 1st communicating path 4 blows in on the first floor as a hierarchy of lower floor space 2 along the 1st countering wall surface 8a. That is, the second air conditioner 7 of the present embodiment supplies the wind from the second floor as the hierarchy of the upper floor space 3 to the first floor as the hierarchy of the lower floor space 2 along the first facing wall surface 8a. be able to.

  Therefore, by using the first air conditioner 6 and the second air conditioner 7 simultaneously, and simultaneously using the first air flow from the first air conditioner 6 and the second air flow from the second air conditioner 7. The air can be easily circulated repeatedly in the order of the lower floor space 2, the second communication passage 5, the upper floor space 3, and the first communication passage 4. As a result, compared with the air conditioning using only one of the first air conditioner 6 and the second air conditioner 7, the lower floor space 2, the upper floor space 3, the first communication passage 4 and the second communication passage 5 The temperature can be homogenized more quickly.

  In the case where the first blowoff flow from the first air conditioner 6 is supplied to the second communication passage 5 along the lower floor surface 19 of the lower space 2 and the second floor surface 14 of the second communication passage 5 , As it is along the second opposing wall surface 12a, ascend to the second floor. Further, the first blowoff flow from the first air conditioner 6 is supplied to the second communication passage 5 without being along the lower floor surface 19 of the lower space 2 and the second floor surface 14 of the second communication passage 5. In the case, it collides with the second opposing wall surface 12a, and a portion thereof ascends to the second floor along the second opposing wall surface 12a.

  In particular, at the time of heating, it is possible to use the nature that warm air rises and the phenomenon that an air flow for supplying the air when the air on the upper floor comes out is generated. That is, the first blow-off flow of the warm air supplied from the first air conditioner 6 to the second communication passage 5 tends to ascend through the second communication passage 5. In addition, the movement of the air by the second blowoff flow from the second air conditioner 7 on the upper floor makes it easy to generate an air flow that replenishes the moved air. As a result, the first blowoff flow can be easily elevated through the second communication passage 5. By utilizing these properties and phenomena at the time of heating, the temperatures of the lower floor space 2, the upper floor space 3, the first communication passage 4 and the second communication passage 5 can be more rapidly equalized.

  Also, the second blowoff flow from the second air conditioner 7 is supplied to the first communication passage 4 along the upper ceiling surface 20 of the upper space 3 and the first ceiling surface 9 of the first communication passage 4 As it is, along the first opposing wall surface 8a, it descends to the first floor. Further, the second blowoff flow from the second air conditioner 7 is not along the upper floor surface 20 of the upper floor space 3 and the first ceiling surface 9 of the first communication passage 4, and along the upper floor surface 21. Or, if it is supplied to the first communication passage 4 without being along the upper floor surface 21, it collides with the first opposing wall surface 8a, and a part of it collides with the first opposing wall surface 8a to the first floor Go down.

  In particular, during cooling, it is possible to utilize the property that cold air descends, and the phenomenon that an air flow for replenishing that part of the air on the lower floor is generated. That is, the second blowoff flow of the cold air supplied from the second air conditioner 7 to the first communication passage 4 easily descends through the first communication passage 4. In addition, the movement of the air by the first blowoff flow from the first air conditioner 6 at the lower floor can facilitate the generation of an air flow that replenishes the moved air. As a result, the second blowoff flow can be easily lowered through the first communication passage 4. By utilizing these properties and phenomena at the time of cooling, the temperatures of the lower layer space 2, the upper layer space 3, the first communication passage 4 and the second communication passage 5 can be more rapidly equalized.

  Next, in the building 1 of the present embodiment, a specific example of a circulation path different from the circulation path of wind shown in FIG. 5 that can be performed using the first air conditioner 6 and the second air conditioner 7 will be described. 6 and 7 are diagrams showing circulation paths different from the circulation path of wind shown in FIG. 6 is a plan view of the first floor of the building 1 similar to FIG. 1 and shows a circulation path of the first blow-off flow which is the wind from the first air conditioner 6. FIG. 7 is a plan view of the second floor of the building 1 similar to FIG. 2 and shows a circulation path of the second blow-off flow which is the wind from the second air conditioner 7.

  Here, although the first air conditioner 6 and the second air conditioner 7 shown in FIGS. 5 to 7 are arranged at the same position, the first air conditioner 6 and the second air conditioner shown in FIGS. In the air conditioner 7, the vertical and horizontal angles of the outlet 6a of the first air conditioner 6 and the vertical direction of the outlet 7a of the second air conditioner 7 in order to make the circulation route of the wind different from the circulation route shown in FIG. The direction and horizontal angle etc. are adjusted. However, it is also possible to change the circulation path of the wind by changing the positions of the first air conditioner 6 and the second air conditioner 7 in plan view. For example, the first air conditioner 6 may be disposed on the first side wall surface 8 c side of the first floor, and the second air conditioner 7 may be disposed on the upper wall surface of the entrance 92 a of the toilet 92. The first air conditioner 6 may be disposed on the lower floor section wall surface 16 or the lower floor ceiling surface 18 of the lower floor space 2. Furthermore, the second air conditioner 7 may be disposed on the upper floor section wall surface 17 or the upper floor ceiling surface 20 of the upper floor space 3.

  First, the circulation path of the first blow-off flow supplied from the first air conditioner 6 shown in FIG. 6 will be described. As shown in FIG. 6, the first air conditioner 6 sends out the wind along one of the pair of second side walls 12b and 12c (the second side wall 12c in the present embodiment), and the second opposing wall 12a, a pair The wind is sent out in the order of the other of the second side wall surfaces 12b and 12c (the second side wall surface 12b in the present embodiment). That is, the first blowoff flow from the first air conditioner 6 shown in FIG. 6 mainly does not ascend from the second communication passage 5 to the upper floor, but uses the second section wall surface 12 that divides the second communication passage 5 Then, it returns to the lower floor space 2 and returns to the first communication passage 4. Thus, according to the circulation path of the wind shown in FIG. 6, compared with the circulation path of the wind shown in FIG. The second communication passage 4 and the second communication passage 5 can be widely spread. That is, the temperature unevenness of the lower floor space 2, the first communication passage 4 and the second communication passage 5 in the first floor as the hierarchy of the lower floor space 2 can be further reduced.

  And according to the 1st air conditioner 6 shown in FIG. 6, after circulating the 1st blowing flow in the 1st floor, it is from the 1st floor which is the hierarchy of lower floor space 2 along the 1st opposite wall surface 8a. Wind can be supplied to the second floor which is a hierarchy of the floor space 3. That is, the first blowoff flow from the first air conditioner 6 shown in FIG. 6 mainly rises from the first communication passage 4 to the second floor.

  Next, the circulation path of the second blow-off flow supplied from the second air conditioner 7 shown in FIG. 7 will be described. As shown in FIG. 7, the second air conditioner 7 sends out the wind along one of the pair of first side wall surfaces 8 b and 8 c (in the present embodiment, the first side wall surface 8 c), and the first opposing wall surface 8 a The wind is sent out in the order of the other of the first side wall surfaces 8b and 8c (the first side wall surface 8b in the present embodiment). That is, the second blowoff flow from the second air conditioner 7 shown in FIG. 7 mainly does not descend from the first communication passage 4 to the lower floor, but uses the first section wall surface 8 that divides the first communication passage 4 Then, it is folded back into the upper floor space 3 and returns to the second communication passage 5. Thus, according to the circulation path of the wind shown in FIG. 7, the second blowoff flow in the second floor as the hierarchy of the upper floor space 3, compared with the circulation path of the wind shown in FIG. The third communication passage 4 and the second communication passage 5 can be widely spread. That is, the temperature unevenness of the upper floor space 3, the first communication passage 4 and the second communication path 5 in the second floor as the hierarchy of the upper floor space 3 can be further reduced.

  And according to the 2nd air conditioner 7 shown in FIG. 7, after circulating the 2nd blowing flow by the 2nd floor, down from the 2nd floor which is a hierarchy of upper floor space 3 along the 2nd opposing wall surface 12a. Wind can be supplied to the first floor, which is the hierarchy of the floor space 2. That is, the second blowoff flow from the second air conditioner 7 shown in FIG. 7 mainly descends from the second communication passage 5 to the first floor.

  Thus, if the circulation path of the wind shown in FIG.6 and FIG.7 is formed, in addition to the efficiency improvement of the circulation of the air of the upper and lower floors, the temperature nonuniformity in each floor can be suppressed.

  Note that, in order to efficiently circulate the wind in the same layer shown in FIG. 6 and FIG. 7, the lower floor section wall surface 16 partitioning the lower floor space 2 and the upper floor section partitioning the upper floor space 3 It is preferable that the wall surface 17 constitute a guide surface on which the wind can easily move between the first communication passage 4 and the second communication passage 5. In the present embodiment, on the first floor, the first side wall surface 8 b of the first section wall surface 8 is linearly continued to the lower floor section wall surface 16. Further, in the second floor, the first side wall surface 8 b of the first section wall surface 8 is linearly continuous with the upper floor section wall surface 17. Furthermore, in the present embodiment, in the first floor, the second side wall surface 12 c of the second section wall surface 12 is linearly continuous with the lower section wall surface 16. Furthermore, in the second floor, the second side wall surface 12 c of the second section wall surface 12 is linearly continued to the upper floor section wall surface 17.

  Therefore, in the first floor, the first air flow from the first air conditioner 6 is linearly formed on the first floor, forming the first side wall surface 8 b and a part of the lower floor section wall 16 (in the present embodiment, the entrance 82 a and the entrance 87 a Along the second wall surface 12c and the second opposite wall surface 12a. In addition, the second blowoff flow from the second air conditioner 7 proceeds along the first side wall surface 8c and the first opposing wall surface 8a in the second floor, and then linearly arranged, the first side wall surface 8b, the upper floor It is guided to the second opposing wall surface 12a along a part of the section wall surface 17 (in the present embodiment, the wall surface on which the inlet / outlet 90a and the inlet / outlet 91a are formed) and the second side wall surface 12c. Thus, it is preferable to guide the movement of the wind between the first communication passage 4 and the second communication passage 5. In other words, at least one of the pair of first side wall surfaces 8b and 8c is continuous with any one of the lower floor partition wall surface 16 and the upper floor partition wall surface 17, and either one of the wall surfaces Is preferably continuous with at least one of the pair of second side wall surfaces 12b and 12c. In particular, as in the present embodiment, it is preferable to be continuous in a straight line.

  As described above, according to the air conditioning system of the building 1 of the present embodiment, the circulation path of the wind shown in FIG. 5 and the circulation path of the wind shown in FIGS. 6 and 7 can be realized. That is, according to the air conditioning system of the present embodiment, one of the two communication paths (the second communication path 5 in the example of FIG. 5 and the example of FIG. Wind can be supplied from the floor of the lower floor space 2 (the first floor in the present embodiment) to the floor of the upper floor space 3 (the second floor in the present embodiment) through the passage 4). Further, according to the air conditioning system of the present embodiment, the second communication path is the other of the two communication paths (the first communication path 4 in the example of FIG. 5 and the second run in the example of FIG. Wind can be supplied from the floor of the upper floor space 3 (the second floor in the present embodiment) to the floor of the lower floor space 2 (the first floor in the present embodiment) through the passage 5). Thus, it is possible to execute the air conditioning method in which the air is circulated in the lower floor space 2 and the upper floor space 3. As a result, the lower floor space 2, the upper floor space 3, the first communication passage 4 and the second communication passage 5 can be air-conditioned to a uniform temperature.

In addition, it is preferable that the building 1 is a high thermal insulation building whose skin | skin average heat transmission coefficient Ua value is 0.6 [W / (m < ² > * K)] or less. When the building 1 is a highly thermally insulated building that satisfies the above Ua value standard, the airtightness is high and the flow of the air flow is improved, so the upper and lower floors using the first air conditioner 6 and the second air conditioner 7 of this embodiment. Uniform air conditioning of the space is more likely to be achieved.

  Finally, a control example of the air conditioning system of the building 1 of the present embodiment will be described. FIG. 8 is a diagram showing an outline of operation control of the air conditioning system.

  As described above, the air conditioning system of the building 1 forms a circulation path of wind using the first air conditioner 6 and the second air conditioner 7 to efficiently equalize the temperature of the upper and lower floors. In order to form such a circulation path of wind, as shown in FIG. 8, the air conditioning system of the present embodiment is provided with a control device 50 for controlling the air volume of the first air conditioner 6 and the second air conditioner 7.

In addition, "at the time of cooling" is the state which set temperature setting to 25 degreeC-28 degreeC, for example. Moreover, "at the time of heating" is a state which set temperature setting to 20 degreeC-25 degreeC, for example.

  Specifically, the control device 50 of the present embodiment makes the air volume of the second air conditioner 7 smaller than the air volume of the first air conditioner 6 during cooling. As described above, since it is possible to utilize the property that cold air descends during cooling, the second blowoff flow from the second air conditioner 7 can be used as the lower floor through the first communication passage 4 or the second communication passage 5. Easy to supply Therefore, at the time of cooling, by making the air volume of the second air conditioner 7 smaller than the air volume of the first air conditioner 6, the energy consumption by the second air conditioner 7 is suppressed, and the temperatures of the upper and lower floors are efficiently reduced. A uniform circulation path of the wind can be formed.

  Conversely, the control device 50 of the present embodiment makes the air volume of the first air conditioner 6 smaller than the air volume of the second air conditioner 7 during heating. As described above, since the property that warm air rises can be used during heating, the first blowoff flow from the first air conditioner 6 can be used as an upper floor through the first communication passage 4 or the second communication passage 5. Easy to supply Therefore, by setting the air volume of the first air conditioner 6 to be smaller than the air volume of the second air conditioner 7 during heating, the energy consumption by the first air conditioner 6 is suppressed, and the temperatures of the upper and lower floors are efficiently reduced. A uniform circulation path of the wind can be formed.

  Further, as shown in FIG. 8, in the air conditioning system of the present embodiment, the lower floor human sensor 51 provided on the first floor as the hierarchy of the lower floor space 2 and the second floor as the hierarchy of the upper floor space 3 And an upper floor human sensor 52 provided. The lower floor human sensor 51 according to this embodiment can detect the presence or absence of a person in the lower floor space 2, the first communication passage 4 and the second communication passage 5 at the position of the first floor. . Further, the upper floor human sensor 52 according to this embodiment can detect the presence or absence of a person in the upper floor space 3, the first communication passage 4 and the second communication passage 5 at the position of the second floor. . The lower floor human sensor 51 and the upper floor human sensor 52 use a camera or the like having a thermo function or an image authentication function in a camera body or a separate body, so that the temperature or pulse of a person such as a resident, the age of a person, Men and women can be identified. The lower floor human sensor 51 may be disposed in the LDK 81 including the lower floor space 2 or may be disposed in the private room 82. In addition, the upper floor human sensor 52 may be disposed in the corridor 93 as the upper floor space 3, or may be disposed in any or all of the private rooms 88 to 91.

  And the control apparatus 50 of this embodiment can control the air volume of the 1st air conditioner 6 and the 2nd air conditioner 7, based on the detection result of the lower floor human sensor 51 and the upper floor human sensor 52. For example, when one human sensor of the lower floor human sensor 51 and the upper floor human sensor 52 detects a human and the other human sensor does not detect a human, the control device 50 performs the first operation. Of the air conditioner 6 and the second air conditioner 7, the air volume of the air conditioner provided in the hierarchy in which the one human sensor is arranged is provided in the hierarchy in which the other human sensor is arranged Make it smaller than the air volume of the air conditioner.

  More specifically, as shown in FIG. 8, when the lower floor human sensor 51 detects a person and the upper floor human sensor 52 does not detect a person, the control device 50 performs the first air conditioning. The air volume of the machine 6 is made smaller than the air volume of the second air conditioner 7. Further, when the lower floor human sensor 51 does not detect a human and the upper floor human sensor 52 detects a human, the control device 50 sets the air volume of the second air conditioner 7 to the first air volume. The air volume of the air conditioner 6 is made smaller. That is, the control device 50 of the present embodiment performs control so as to reduce the air volume of the air conditioner installed in the hierarchy where people are present. By controlling in this manner, it is possible to suppress direct contact of the wind supplied from the air conditioner with a person, and to make it difficult for the user to feel discomfort due to the wind. The control device 50 executes control to reduce the air volume of one air conditioner, but may also execute control to increase the air volume of the other air conditioner.

  Furthermore, the control device 50 compares the number of people detected by the lower floor human sensor 51 with the number of people detected by the upper floor human sensor 52, and the number of people detected is smaller. Control the air volume of the air conditioner in the hierarchy where the human detection sensor is installed to be smaller than the air volume of the air conditioner in the hierarchy where the human detection sensor with a large number of detected people is installed It is also good.

  In addition, the control device 50 of the present embodiment is configured such that the air volume of the first air conditioner 6 and the second air conditioner 7 maintain the sum of the air volumes of the first air conditioner 6 and the second air conditioner 7 to be a predetermined value or more. It is preferable to control the air flow. By setting the threshold value in this manner, it is possible to suppress the amount of wind blown from the air conditioner from being lowered to such an extent that smooth wind circulation on the upper and lower floors can not be performed.
