Radio transmission is performed to the indoor unit 4 via the communication unit 33 at regular time intervals (for example, 1 minute intervals).

Subsequently, the unique functions of the control board 46 included in the indoor unit 4 will be described in detail. As shown in FIG. 6, functionally, the control board 46 has a biological data acquisition unit 400, a start necessity determination unit 401, a clothing amount estimation unit 402, a hot / cold feeling estimation unit 403, and an operation command unit. It is equipped with 404. These functional units are realized by the CPU 463 executing the above-mentioned air conditioning control program stored in the secondary storage device 466.

The biometric data acquisition unit 400 is an example of the biometric data acquisition means according to the present invention. The biometric data acquisition unit 400 receives the above-mentioned measurement data sent periodically (for example, every minute) from the biometric data measuring device 3. The biological data acquisition unit 400 extracts and acquires each biological data (that is, body temperature, heart rate, and sweating amount) from the received measurement data.

Specifically, as shown in FIG. 7, when the difference (ΔT) between the body temperature and the clothing surface temperature is smaller than the predetermined first threshold value, the clothing amount estimation unit 402 has a small clothing amount for the user. That is, it is presumed to be light clothing. When ΔT is equal to or greater than the first threshold value and equal to or less than a predetermined second threshold value, the clothing amount estimation unit 402 estimates that the clothing amount of the user is normal. When ΔT is larger than the second threshold value, the clothing amount estimation unit 402 estimates that the clothing amount of the user is thick clothing.

The thermal sensation estimation unit 403 estimates the user's feeling for the current thermal environment, that is, the thermal sensation, based on the user's clothing amount estimated by the clothing amount estimation unit 402. Specifically, when the user's clothing amount is heavy, the heating / cooling sensation estimation unit 403 estimates that the user feels cold. Further, when the user's clothing amount is light, the heating / cooling sensation estimation unit 403 estimates that the user feels hot. When the user's clothing amount is normal, the heating / cooling feeling estimation unit 403 estimates that the user feels neither hot nor cold (that is, comfortable).

The operation command unit 404 determines the content of the air-conditioning control based on the user's temperature-cooling sensation estimated by the temperature-cooling sensation estimation unit 403, and the fan 40, the louver 41, and the outdoor unit 5 are determined according to the determined air-conditioning control content. Generates a control command for each to operate and sends it to each.

Specifically, the operation command unit 404 generates a control command for strengthening the heating for each of the fan 40, the louver 41, and the outdoor unit 5 when the user feels cold during the heating operation. In this case, for example, a control command for raising the set temperature (also referred to as a target temperature) by 1 to 3 ° C. or increasing the amount of air blown is generated.

Further, the operation command unit 404 generates a control command for weakening the heating for each of the fan 40, the louver 41, and the outdoor unit 5 when the user feels that it is hot during the heating operation. In this case, for example, a control command for lowering the set temperature by 1 to 3 ° C. or lowering the air flow rate is generated.

Further, the operation command unit 404 generates a control command for strengthening the cooling for each of the fan 40, the louver 41, and the outdoor unit 5 when the user feels that it is hot during the cooling operation. In this case, for example, a control command for lowering the set temperature by 1 to 3 ° C. or increasing the amount of air blown is generated.

Further, the operation command unit 404 generates a control command for weakening the cooling for each of the fan 40, the louver 41, and the outdoor unit 5 when the user feels cold during the cooling operation. In this case, for example, a control command for raising the set temperature by 1 to 3 ° C. or lowering the air flow rate is generated.

The start necessity determination unit 401, the clothing amount estimation unit 402, the heating / cooling sensation estimation unit 403, and the operation command unit 404 are examples of the air conditioning control means according to the present invention.

FIG. 8 is a flowchart showing a procedure of air conditioning control processing executed by the control board 46 of the indoor unit 4. The air conditioning control process is started when the user enters the room R.

When the start necessity determination unit 401 determines that the comfort control needs to be started (step S101: YES), the clothing amount estimation unit 402 estimates the clothing amount of the user in the room R (step S102). The warm / cool feeling estimation unit 403 estimates the user's current warm / cold feeling based on the user's clothing amount estimated by the clothing amount estimation unit 402 (step S103).

The operation command unit 404 determines the content of the air conditioning control based on the user's hot / cold feeling estimated by the hot / cold feeling estimation unit 403 (step S104). The operation command unit 404 generates a control command for each of the fan 40, the louver 41, and the outdoor unit 5 based on the determined content of the air conditioning control (step S105). Then, the operation command unit 404 transmits each generated control command to each of the fan 40, the louver 41, and the outdoor unit 5 (step S106).

When a predetermined waiting time (for example, 10 minutes) elapses after the process of step S106 (step S107; YES), the CPU 463 of the control board 46 determines whether or not the user has left the room R (step S108). ). Whether or not the user has left the room R can be determined from the communication status with the biological data measuring device 3 or the thermal image in the room R. That is, the CPU 463 may determine that the user has left the room if the communication with the biometric data measuring device 3 is not possible, and if no person is reflected in the thermal image in the room R, the user leaves the room. It may be determined that it has been completed.

If the user has left the room (step S108; YES), the CPU 463 ends the air conditioning control process. On the other hand, if the user has not left the room (step S108; NO), the process returns to step S102.
