The second suction port 8 is provided near the opposing wall 21 on the ceiling 23. The second suction port 8 is provided as an opening for sucking the air in the living space 1. Here, the vicinity means a distance within 1 m.

  The second outlet 4 is a rectangular opening and has, for example, a slit shape. The second outlet 4 is arranged near the windowed wall side of the ceiling 23 such that the long side of the slit shape is parallel to the windowed wall 20. Here, the term “parallel” does not need to be strictly parallel, and includes parallel if the long side is provided along the windowed wall 20. In addition, the vicinity means a distance within 1 m. The long side of the second suction port 8 in the slit shape has a width equal to or larger than that of the window 3. Here, the width of the window 3 refers to the width of the frame for fixing the window provided around the window, not the width of the opening. The direction in which the second outlet 4 blows out the air is the direction away from the windowed wall 20, that is, the direction of the opposing wall 21.

  As shown in FIG. 2, the blower 6 guides air from the second inlet 8 to the second outlet 4. In other words, the blower 6 generates a flow of air from the second inlet 8 to the second outlet 4. That is, the blower 6 sucks the air in the living space 1 from the second suction port 8 and supplies the air into the living space 1 from the second outlet 4. In other words, the second outlet 4 supplies the air blown out by the blower 6 to the living space 1. That is, the air supplied by the blower 6 circulates in the living space 1.

  The blower 6 changes the wind speed of the air blown from the second outlet 4. It is preferable that the blower 6 performs an operation in which the wind speed fluctuates like a natural wind. Specifically, for example, speed control based on the 1 / f fluctuation theory as disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2-218892) may be used. The installation location of the blower 6 is not particularly specified. In FIG. 2, the blower 6 is provided outside the living space 1, but may be provided inside the living space 1, for example.

The first outlet 2 is provided at a peripheral portion of the ceiling 23 of the living space 1. Specifically, the first outlet 2 is provided at a peripheral portion of the ceiling 23 and farther from the second outlet 4 with respect to the window-equipped wall (a position closer to the opposing wall 21). By providing the first outlet 2 at the peripheral portion, it is difficult for the air blown out from the first outlet 2 to directly hit the occupant. Here, the peripheral portion refers to a region extending within a distance of 1 m from the edge of the ceiling 23.

  The circulation air conditioner 5 heats and cools the air sucked from the first suction port 7, that is, adjusts the temperature, and then blows out the temperature-controlled air from the first outlet 2.

  The above is the configuration of the indoor air conditioning system. In the above configuration, the circulation air conditioner 5 sucks the air in the living space 1 from the first suction port 7, cools or heats the air, and then supplies the air from the first air outlet 2 to the room. Although not shown, the circulating air conditioner 5 controls the temperature of the living space 1 based on the room temperature detected by the temperature sensor provided in the living space 1 and a set temperature set by the occupant. I have.

That is, the air whose temperature has been adjusted by the circulating air conditioner 5 is vertically stirred by the air whose temperature has not been adjusted from the second outlet 4, and circulates in the living space 1. Therefore, the air whose temperature has been adjusted by the circulation air conditioner 5 spreads throughout the living space 1 and enhances the temperature control function in the living space 1. Then, the temperature difference due to the position in the living space 1 can be reduced, and the occupants in the living space 1 can be prevented from giving an uncomfortable feeling due to the temperature difference.

  In winter, it may feel cold when it hits the wind directly. In addition, in the summertime, a cold wind may directly hit the vehicle, giving a sense of incongruity. However, according to the indoor air conditioning system according to the present embodiment, when the temperature of the living space 1 is adjusted to the set temperature by the circulation air conditioner 5, the air directly heated and cooled by the circulation air conditioner 5 is used. Is blown downward from a first outlet provided at the peripheral portion of the ceiling 23 and does not directly hit a resident near the center of the living space 1. Then, the air mixed in the living space 1 and adjusted to an appropriate temperature is blown out from the second window 4 by the blower 6, and the air flowing from the wall 20 with a window to the facing wall 21 in the living space 1. To form a flow. For this reason, an indoor air-conditioning system that can comfortably feel the natural wind even in winter or summer.

  Further, the width in the longitudinal direction of the second outlet 4 is set to be substantially the same as the width of the window 3, so that the wind blown out from the second outlet 4 feels like blowing from the window 3. Is obtained.

  Further, the wind blown out from the second outlet 4 is separated from the window 3 and spreads from the vicinity of the floor near the center of the living space 1 to the position of the resident's head as shown in FIG. Is blowing out. That is, the wind blown from the second blowout port 4 blows out from the window 3 toward the living space. At this time, the position of the occupant's head is different depending on the case, for example, a head in a state of sitting on a chair or a head in a standing state, and is set by a command to a control unit described later. be able to. Here, in general, the living area refers to a range from the floor 24 to a height of 1.8 m. In the ISO, the height of the head in a standing position is 1.7 m, and the wind blown out from the second outlet 4 may be directed to the height of 1.7 m at the position where the resident stands.

  The installation location of the circulation air conditioner 5 is not specified. In FIG. 2, the circulation air conditioner 5 is provided outside the living space 1, but may be provided inside the living space 1.

  Although not shown, the second air outlet 4 has a wind direction adjusting plate arranged in parallel from the window 3 side to the interior side of the living space 1. The wind direction adjusting plate is, for example, a flap. The wind direction adjusting plate (not shown) adjusts the angle of the airflow blown into the living space 1 by adjusting the angle. When the occupant is sitting, the airflow blows toward a slightly lower position (indicated as airflow W1 in FIGS. 1 and 2), and when the resident is standing, the airflow is angled to reach a higher position. Adjustment (indicated as airflow W2 in FIGS. 1 and 2). The control device that controls the blower 6 adjusts the angle of the wind direction adjusting plate by a stepping motor (not shown) provided inside the second outlet 4. The resident may issue an instruction to adjust the angle of the wind direction adjustment plate using a remote control device (not shown). In addition, the angle adjustment of the wind direction adjustment plate may be instructed by recognizing the position and orientation of the occupant by the output of a human body detection sensor (not shown) provided in the living space 1 and based on the position information. .

  As described above, the second outlet 4 has the wind direction adjusting plate parallel to the longitudinal direction. Then, the angle of the wind direction adjustment plate is adjusted so that the wind reaches a range of 1.7 m above the floor of the living space 1.
