  When the portable SIP phones 4a, 4b, 4c,... Are replaced with active RFID tags, the wireless LAN access points 10a, 10b, 10c,. Similarly, when a passive RFID tag is replaced, the wireless LAN access points 10a, 10b, 10c... Are replaced with RFID tag readers. In this case, the RFID tag reader is placed on a desk with an RFID tag reader (for example, The personal ID is recognized when a user holds up an ID card or the like with his / her RFID tag. Further, when the user logs in to the personal computer, the personal ID may be recognized and the position may be detected from the position of the personal computer where the user has logged in. The seating in these cases is determined by whether or not the temperature sensors 31a, 31b,... Installed in the chair near the position of the RFID tag reader and the personal computer where the user logs in exceed 30 ° C. Will be. In this case, the concept of the time field of the air conditioning system 1 according to the previous embodiment is eliminated.

(E)

  However, in such a case, the indoor unit corresponding to the chair ID data corresponding to the temporary link field in which two or more personal identification number data exists (actually, the room blowing to the actual chair corresponding to the chair ID data) Machine) may be stopped.

  In this way, the holders of other portable SIP phones 4a, 4b, 4c,... Standing around the holder of the portable SIP phones 4a, 4b, 4c,. Can prevent the environment from becoming uncomfortable.

  Separately from this, an air conditioning desired field is provided in the personal information table Tm1, and data on whether air conditioning is desired in the above case is stored for each individual, and the air conditioning corresponding to the personal identification number data existing in the temporary link field is stored. If the desired air conditioning desired data among the desired data is dominant, the conditioned air may be blown to the corresponding portions of the indoor units 20a, 20b, 20c,. In addition, the case where “present” air conditioning desired data is dominant is, for example, when all the air conditioning desired data corresponding to the personal identification number data existing in the temporary link field is “present” or in the temporary link field. This is the case, for example, when the air conditioning request data corresponding to the existing personal identification number data is “present” or more.

(I)
In the air conditioning system 1 according to the previous embodiment, when the time data is 60 seconds or more and the temperature data exceeds 30 ° C., “1” is input to the seating state field of the record. However, the threshold value of 30 ° C. or the threshold value of 60 seconds can be arbitrarily changed.

  As a threshold value of time data, for example, when a sales representative who frequently goes out is a target, this threshold value is preferably a time of 30 seconds or less. Further, as a threshold value of the temperature data, for example, when the air conditioner is not operated in the summer, when the temperature of the chair rises to nearly 30 ° C. without a person sitting, this threshold is not 30 ° C. but 30 ° C. It is considered that a higher numerical value (for example, 35) is preferable. Considering such a case, it is possible to determine whether or not the temperature data threshold is more accurately determined by setting different values for each season.

(J)
In the air conditioning system 1 according to the previous embodiment, the case where the temperature exceeds 30 ° C. is set as one of the determination conditions for sitting on the chair, but not limited to this, the temperature sensors 31a, 31b,. For example, the temperature may rise above 1 ° C. in 5 minutes. When determining whether or not the user is seated on the chair in this manner, the temperature detected by the temperature sensors 31a, 31b,... The temperature may rise above 1 ° C. per minute, or may rise above 2 ° C. over 5 minutes. In addition, it is considered that this threshold value is more preferable if different values are provided for each season because it is possible to more accurately determine whether or not the user is seated on the chair.

(K)
In the air conditioning system 1 according to the previous embodiment, when the flaps and louvers provided at the outlets of the indoor units 20a, 20b, 20c,.

However, the chair ID data is prioritized and weighted in advance, and the flaps and louvers provided at the outlets of the indoor units 20a, 20b, 20c,. However, if the chair ID data has higher priority or higher weight, the flaps and louvers provided at the outlets of the indoor units 20a, 20b, 20c,. The flaps and louvers provided at other air outlets may be the targets of the previous air conditioning control. Further, when control that emphasizes energy saving rather than comfort is selected, flaps and louvers provided at the same outlet may be targeted for the previous air conditioning control and the subsequent air conditioning control. In such a case, the previous air conditioning control and the subsequent air conditioning control are executed alternately.

(L)
The air conditioning system 1 according to the previous embodiment uses the result of the individual optimum air conditioning experiment for specifying the individual “constitution”, but it may be derived by the comfort equation (PMV).

  The “comfort equation (PMV)” here is calculated based on temperature, humidity, wind speed, radiation temperature, (individual) activity amount, and (individual) clothing amount. Also, when using this comfort equation (PMV), a radiation temperature is required, but this radiation temperature may be actually measured by providing a sensor for each room, or instead of actually providing a sensor. You may make it obtain | require by simulation. In addition, when calculating | requiring radiation temperature by simulation, it can consider calculating | requiring based on the solar radiation angle etc. by a season, a time slot | zone, etc., the cloud amount correction | amendment by weather information, etc.

(M)
In the air conditioning system 1 according to the previous embodiment, in order to perform airflow control on the individual user, the position of the individual user is obtained by various algorithms. The position may be set, and airflow control may be performed based on the setting. In this case, even if the position of the individual user or the desk layout in the office changes, the setting may be changed so that the setting can be changed according to the changed situation.

(N)
In the air conditioning system 1 according to the previous embodiment, the airflow control pattern table Tm2 has 24 patterns from the A pattern to the X pattern, but is not limited to this. For example, the “air volume” is controlled for each indoor model. It may be classified into a possible level, or the “wind temperature” may be set not only to a cooling setting of 18 ° C., 20 ° C., and 22 ° C. but also to a heating setting such as 24 ° C., 26 ° C., and 28 ° C. , “Blasting time” may be a long time such as 15 minutes or 20 minutes.

  When the “wind temperature” is set to the heating setting, the “wind application time” is preferably set to 10 minutes, 15 minutes, longer time than the case of the cooling setting such as temperature interlocking, etc. It is preferable to use a floor surface where no one is present, instead of the neck of the user in the case of the cooling setting (the above embodiment). Furthermore, in such a heating setting, the temperature detected by the temperature sensor is a predetermined body temperature, and the individual sweating state is in a normal state (that is, the humidity sensor reaches a predetermined humidity). Airflow control (that is, individual heating operation) is performed.

  The air conditioning system according to the present invention can distinguish between a state immediately after perspiration and a state in which a certain amount of time has passed since sweating, so that it becomes a comfortable environment according to the physiological state of the user at that time. Therefore, it is useful as an air conditioner that detects whether a person is sitting on a seat and provides a comfortable space for the person.
