The above range is larger as the ceiling is higher.

The control device 11 further includes an actually measured data storage unit 15 that stores the actually measured data received by the receiving unit 12.

FIG. 5 shows the temperature distribution when one person is present in the range 20 in which the temperature detecting unit 7 detects the temperature when the height of the ceiling is the first height HA. Furthermore, FIG. 5 shows that the temperature distribution in the first combination included in the reference data is associated with the first height HA. FIG. 5 shows that the range 20 is divided into a region A having a relatively high temperature and a region having a relatively low temperature. A diagonal line is added to the region A where the temperature is relatively high, and no diagonal line is added to the region where the temperature is relatively low. The size of the region A, which has a relatively high temperature, is associated with the first height HA.

FIG. 6 shows the temperature distribution when one person is present in the range 20 in which the temperature detecting unit 7 detects the temperature when the height of the ceiling is the second height HB. Furthermore, FIG. 6 shows that the temperature distribution in the second combination included in the reference data is associated with the second height HB. The second height HB is lower than the first height HA. The range 20 of FIG. 6 is smaller than the range 20 of FIG. FIG. 6 shows that the range 20 is divided into a region B having a relatively high temperature and a region having a relatively low temperature. A diagonal line is added to the region B where the temperature is relatively high, and no diagonal line is added to the region where the temperature is relatively low.

The size of the area where the temperature is relatively high in the presence of a person is smaller as the height of the ceiling is higher.

FIG. 7 is a diagram for explaining an example of a method for determining the height of the ceiling performed by the determination unit 16 of the ceiling-embedded air conditioner 1 according to the first embodiment. In FIG. 7, those assigned the reference numeral “A” indicate the region A in which the temperature is relatively high in FIG. Those to which the reference numeral "B" is assigned indicate the region B in which the temperature is relatively high in FIG.

The symbol "C1" indicates the temperature when one person is present in the range 20 in which the temperature detecting unit 7 detects the temperature after the embedded portion 2 is embedded in the ceiling higher than the first height HA. It shows a region where the temperature is relatively high in the temperature distribution detected by the part 7. For example, the region assigned the symbol "C1" is a region from the highest temperature in the temperature distribution detected by the temperature detection unit 7 to a temperature lower than the highest temperature by a predetermined second temperature. ..

The symbol "C2" is a temperature detection unit 7 when there is one person in the range 20 after the embedded portion 2 is embedded in the ceiling having the first height HA or less and the second height HB or more.

For example, the region assigned the symbol "C3" is a region from the highest temperature in the temperature distribution detected by the temperature detection unit 7 to a temperature lower than the highest temperature by a predetermined second temperature. ..

The region X is a region where the height of the ceiling is higher than the first height HA. The region Y is a region where the height of the ceiling is equal to or greater than the second height HB and equal to or less than the first height HA. Region Z is a region where the height of the ceiling is lower than the second height HB.

FIG. 8 is a flowchart showing an example of an operation procedure performed when the ceiling-embedded air conditioner 1 according to the first embodiment determines the height H of the ceiling of the room 8. After the embedded portion 2 is embedded in the ceiling of the room 8, the person 10 causes the remote control device 9 of FIG. 3 to determine the ceiling height H of the room 8 by the ceiling-embedded air conditioner 1. When the operation of is performed, the remote control device 9 transmits a signal indicating an instruction for determining the height H of the ceiling of the room 8 to the ceiling-embedded air conditioner 1. After performing the above operation, the person 10 moves vertically downward of the embedded portion 2.

In the ceiling-embedded air conditioner 1, the receiving unit 12 receives the signal transmitted from the remote control device 9. The control unit 13 causes the temperature detection unit 7 to detect the temperature. The receiving unit 12 receives actual measurement data indicating the temperature distribution detected by the temperature detecting unit 7 from the temperature detecting unit 7 (S1). The actual measurement data storage unit 15 stores the actual measurement data received by the reception unit 12. The region from the highest temperature in the temperature distribution shown by the measured data to the temperature lower than the highest temperature by a predetermined second temperature is defined as the measurement region C.

The determination unit 16 acquires the reference data stored in the reference data storage unit 14 and the actual measurement data stored in the actual measurement data storage unit 15. The determination unit 16 determines whether or not the size of the measurement region C specified by the actual measurement data is smaller than the size of the region A having a relatively high temperature in the first combination included in the reference data (S2). In FIG. 8, the size of the measurement area C is described as “measured C”. In step S2 of FIG. 8, the size of the relatively high temperature region A of the first combination included in the reference data is described as “reference A”.

When the determination unit 16 determines that the size of the measurement region C is smaller than the size of the region A where the temperature is relatively high in the first combination (Yes in S2), the ceiling height H of the room 8 is the second. It is determined that the height of 1 is higher than HA (S3). That is, in step S3, the determination unit 16 determines that the ceiling height H of the room 8 belongs to the region X. When the determination unit 16 determines that the size of the measurement region C is equal to or larger than the size of the region A having a relatively high temperature in the first combination (No in S2), the size of the measurement region C is the reference data. It is determined whether or not the temperature of the second combination contained in the above is larger than the size of the region B having a relatively high temperature (S4). In step S4 of FIG. 8, the size of the relatively high temperature region B of the second combination included in the reference data is described as “reference B”.

When the determination unit 16 determines that the size of the measurement region C is larger than the size of the region B where the temperature is relatively high in the second combination (Yes in S4), the ceiling height H of the room 8 is the second. It is determined that the height of 2 is lower than HB (S5). That is, in step S5, the determination unit 16 determines that the ceiling height H of the room 8 belongs to the region Z. When the determination unit 16 determines that the size of the measurement region C is equal to or less than the size of the region B having a relatively high temperature in the second combination (No in S4), the height H of the ceiling of the room 8 is , It is determined that the second height is HB or more and the first height is HA or less (S6). That is, in step S6, the determination unit 16 determines that the ceiling height H of the room 8 belongs to the region Y.

As described above, the ceiling-embedded air conditioner 1 according to the first embodiment has a temperature detection unit 7 attached to a plate portion 3 not embedded in the ceiling of the room 8 and a determination unit 16. The determination unit 16 was detected by the temperature detection unit 7 when there was one person in the range 20 in which the temperature detection unit 7 detects the temperature after the embedded unit 2 was embedded in the ceiling of the room 8. The ceiling height H of the room 8 is determined based on the temperature distribution and the reference data for determining the ceiling height H of the room 8.

That is, the ceiling-embedded air conditioner 1 determines the height H of the ceiling of the room 8 without using a camera. The temperature detection unit 7 is cheaper than the camera. In the ceiling-embedded air conditioner 1, the height of the ceiling of the room 8 is based on the temperature distribution and the reference data detected by the temperature detection unit 7 after the embedded portion 2 is embedded in the ceiling of the room 8. Since the temperature H is determined, the height H of the ceiling of the room 8 can be appropriately determined. Therefore, the ceiling-embedded air conditioner 1 according to the first embodiment is relatively inexpensive, and the height H of the ceiling in which the embedded portion 2 is embedded can be appropriately determined.

Embodiment 2.
Next, the ceiling-embedded air conditioner according to the second embodiment will be described. The configuration of the ceiling-embedded air conditioner according to the second embodiment is the same as the configuration of the ceiling-embedded air conditioner 1 according to the first embodiment. That is, the ceiling-embedded air conditioner 1 according to the second embodiment is the ceiling-embedded air conditioner 1 according to the first embodiment. In the second embodiment, the differences from the first embodiment will be mainly described.

As shown in FIG. 4, the ceiling-embedded air conditioner 1 has a temperature distribution data storage unit 17, an estimation unit 18, and a vane 19. As described in the first embodiment, the temperature distribution data storage unit 17 shows the temperature distribution detected by the temperature detection unit 7 used by the determination unit 16 to determine the height H of the ceiling of the room 8. Store distribution data.

The estimation unit 18 estimates the number of people present in the room 8 after the determination unit 16 determines the height H of the ceiling of the room 8. Specifically, the estimation unit 18 determines the temperature distribution detected by the temperature detection unit 7 and the temperature stored in the temperature distribution data storage unit 17 after the determination unit 16 determines the height H of the ceiling of the room 8. The number of people existing in the room 8 is estimated based on the distribution data.

FIG. 9 is a diagram 1 for explaining a method of estimating the number of people existing in the room 8 performed by the estimation unit 18 of the ceiling-embedded air conditioner 1 according to the second embodiment. In FIG. 9, the temperature is relatively high in the range 20 in which the temperature detection unit 7 detects the temperature, the first region 21A having a relatively high temperature, the second region 21B having a relatively high temperature, and the second region 21B having a relatively high temperature. It shows the situation where the third region 21C is included.

The size of the first region 21A having a relatively high temperature in FIG. 9 is about four times the size of the region having a relatively high temperature indicated by the temperature distribution data stored in the temperature distribution data storage unit 17. I assume there is. It is assumed that the size of the second region 21B having a relatively high temperature in FIG. 9 is about three times the size of the region having a relatively high temperature shown by the temperature distribution data. It is assumed that the size of the third region 21C having a relatively high temperature in FIG. 9 is about one time the size of the region having a relatively high temperature shown by the temperature distribution data.

In the situation shown in FIG. 9, since the size of the first region 21A having a relatively high temperature is about four times the size of the region having a relatively high temperature shown by the temperature distribution data, the estimation unit 18 Estimates that there are four people in the first region 21A where the temperature is relatively high. Similarly, the estimation unit 18 estimates that there are three people in the second region 21B where the temperature is relatively high and one person in the third region 21C where the temperature is relatively high. That is, the estimation unit 18 estimates that there are eight people in the room 8.

FIG. 10 is a second diagram for explaining a method of estimating the number of people existing in the room 8 performed by the estimation unit 18 of the ceiling-embedded air conditioner 1 according to the second embodiment. In FIG. 10, the temperature is relatively high in the range 20 in which the temperature detecting unit 7 detects the temperature, the first region 22A having a relatively high temperature, the second region 22B having a relatively high temperature, and the second region 22B having a relatively high temperature. It shows the situation where the third region 22C is included.

The size of the first region 22A having a relatively high temperature in FIG. 10 is about three times the size of the region having a relatively high temperature indicated by the temperature distribution data stored in the temperature distribution data storage unit 17. I assume there is. It is assumed that the size of the second region 22B having a relatively high temperature in FIG. 10 is about twice the size of the region having a relatively high temperature shown by the temperature distribution data. It is assumed that the size of the third region 22C having a relatively high temperature in FIG. 10 is about one time the size of the region having a relatively high temperature shown by the temperature distribution data.

In the situation shown in FIG. 10, since the size of the first region 22A having a relatively high temperature is about three times the size of the region having a relatively high temperature shown by the temperature distribution data, the estimation unit 18 Estimates that there are three people in the first region 22A where the temperature is relatively high. Similarly, the estimation unit 18 estimates that there are two people in the second region 22B where the temperature is relatively high and one person in the third region 22C where the temperature is relatively high. That is, the estimation unit 18 estimates that there are 6 people in the room 8.

As described above, in the situation shown in FIG. 9, the estimation unit 18 has four persons in the first region 21A having a relatively high temperature and three persons in the second region 21B having a relatively high temperature. It is estimated that one person is present in the third region 21C, which is present and has a relatively high temperature. In the situation shown in FIG. 10, in the estimation unit 18, there are three people in the first region 22A where the temperature is relatively high, and two people are present in the second region 22B where the temperature is relatively high, and they are relative to each other. It is estimated that there is one person in the third region 22C where the temperature is relatively high. That is, the estimation unit 18 also has a function of estimating a place where a person existing in the room 8 is located. The control unit 13 has a function of controlling the orientation of the vane 19.

As described in the first embodiment, the vane 19 is set to have a direction for determining the direction of the air blown out from the air outlet in the left-right direction. Although only one vane 19 is shown in FIG. 4, in reality, the vane 19 is provided at each of the first outlet 5a, the second outlet 5b, the third outlet 5c, and the fourth outlet 5d. ing. The control unit 13 controls the orientation of the vanes 19 according to the number of people present in each of the plurality of locations in the room 8 estimated by the estimation unit 18.

As described above, in the ceiling-embedded air conditioner 1 according to the second embodiment, the temperature distribution detected by the temperature detection unit 7 after the determination unit 16 determines the ceiling height H of the room 8. The number of people existing in the room 8 is estimated based on the temperature distribution data stored in the temperature distribution data storage unit 17. That is, the ceiling-embedded air conditioner 1 according to the second embodiment can estimate the number of people existing in the room 8 after the determination unit 16 determines the height H of the ceiling of the room 8. ..

Furthermore, the estimation unit 18 estimates the number of people present in the room 8 based on the temperature distribution and the temperature distribution data detected by the temperature detection unit 7. When estimating the number of people existing in the room 8, the estimation unit 18 is not the reference data, but is detected by the temperature detection unit 7 used by the determination unit 16 to determine the height H of the ceiling of the room 8. Use temperature distribution data showing the temperature distribution. Therefore, the ceiling-embedded air conditioner 1 according to the second embodiment can estimate the number of people existing in the room 8 more accurately than when the reference data is used.

As described above, the estimation unit 18 estimates the place where the person existing in the room 8 is located.
