For example, the air conditioning control device 30 has a function of controlling the operating frequency of the compressor 21 based on the operation information WI of the heat generating devices EDa to EDd. For example, as shown in FIG. 1, it is assumed that the heat generating devices EDa and EDb are operating at an operation rate of 80% and the heat generating devices EDc and EDd are stopped (operation rate is 0%). When the operation information WI of all the heat generating devices EDa to EDd installed in the air conditioned space R is 100%, the average value of the operation information WI of the heat generating devices EDa to EDd in the air conditioned space R shown in FIG. %become.

By controlling the compressor 21 and the indoor fan described above, the power consumption of the indoor fan 11 can be reduced even when, for example, the power stored in the entire building is allocated to a plurality of indoor units 10 using solar panels. Can be suppressed.

In addition, although the air-conditioning control apparatus 30 illustrated about the case where the average value of the whole operation rate in the air-conditioning space R was used as a ratio of an operating frequency or the ratio of the rotation speed of the indoor fan 11, it is related with operation information WI and is a compressor. What is necessary is just to set the operating frequency of 21 or the rotation speed of the indoor fan 11.

Furthermore, the air conditioning control device 30 has a function of controlling the direction of the wind direction adjusting plate 12 based on the operation information WI and the position information PI of the heat generating devices EDa to EDd. For example, when the heating devices EDa to EDd are in the operating state shown in FIG. 1, the air conditioning control device 30 adjusts the direction of the wind direction adjusting plate 12 so that air is blown to the operating heating devices EDa and EDb. .

Further, the air conditioning control device 30 has a function of controlling the camera 13 so as to photograph the inside of the air conditioned space R based on the operation information WI and the position information PI. For example, when the air conditioning controller 30 detects the heat generating devices EDa and EDb that are operating based on the operation information WI, the air conditioning control device 30 adjusts the shooting position of the camera 13 based on the detected position information PI of the heat generating devices EDa and EDb. The camera 13 captures the heat generating devices EDa and EDb that are operating, and transmits the captured images to the air conditioning control device 30 via the data transmission unit 15. As a result, the air conditioning control device 30 can grasp the operating status of each of the heat generating devices EDa and EDb, and can visually browse to what extent the heat generating devices EDa to EDd are processing. .

The operation information WI and the position information PI received by the wireless reception unit 14 of the indoor unit 10 are sent to the air conditioning control device 30 via the signal line SL.

In the air conditioning control device 30, the operations of the indoor unit 10 and the outdoor unit 20 are controlled based on the operation information WI and the position information PI (step ST2). For example, based on the operation information WI and the position information PI, the operating frequency of the compressor 21, the rotational speed of the indoor fan 11, the direction of the wind direction adjusting plate 12, and the shooting position of the camera 13 are determined (step ST3). Thereafter, the operation of the air conditioner 1 such as the operating frequency of the compressor 21 determined in the air conditioning control device 30, the rotational speed of the indoor fan 11 and the direction of the wind direction adjusting plate 12, and the photographing position of the camera 13 is controlled (step). ST4).

That is, when performing air-conditioning control based on a signal transmitted from a mobile terminal as in the past, it becomes impossible to perform air-conditioning control that matches the state of the air-conditioned space because the battery of the mobile terminal runs out, Comfort may be compromised. On the other hand, in the air conditioner 1 of FIG. 3, since the air conditioning control is performed based on the signals from the radio transmitters RTa to RTd that are supplied with power from the heat generating devices EDa to EDd, the radio transmitters RTa to RTd are always connected. Electric power can be secured, and it is possible to prevent the comfort of the air-conditioned space from being damaged by running out of batteries.

Furthermore, since the air conditioning control device 30 performs air conditioning control according to the operation information WI and position information PI of the heat generating devices EDa to EDd, useless air blowing can be suppressed and the energy saving effect can be improved. Specifically, when the air conditioning controller 30 controls the operating frequency of the compressor 21 or the rotation speed of the indoor fan 11 based on the operation information WI of the heat generating devices EDa to EDd, the operation information of the heat generating devices EDa to EDd. Since the air conditioning control is performed according to the WI, it is possible to suppress the temperature of the heat generating devices EDa to EDd from rising excessively.

Further, when the air conditioning control device 30 controls the direction of the wind direction adjusting plate 12 based on the position information PI of the heat generating devices EDa to EDd, for example, cold air is pinpointed with respect to the heat generating devices EDa to EDd having a high temperature. Cold air can be emitted only to places where the room temperature is high, such as lowering the contact temperature. Accordingly, it is not necessary to emit cold air to a useless place such as a place where the heat generation amount of the heat generating devices EDa to EDd is small and the temperature is not high, so that the energy saving effect can be improved.

Further, when the air conditioning control device 30 controls the shooting position of the camera 13 so as to capture the heat generating devices EDa to EDd based on the operation information WI and the position information PI of the heat generating devices EDa to EDd, the image is taken by the camera 13.
