If it is determined that the error is likely to occur, an abnormality identification code corresponding to the content of the abnormality is transmitted to the air conditioning controller 60 via the inter-device communication units 124a, 124b, 424a, 424b, the controller communication units 225a, 225b, and the like. When the abnormality confirmation unit 62 of the air conditioning controller 60 recognizes the abnormality identification code, the outdoor units 20a and 20b, the indoor units 10a and 10b, and the total heat exchange units 40a and 40b are connected via the communication unit 64 and the abnormality confirmation unit 62. The various signals and information transmitted in this manner start to be accumulated in the abnormal data accumulation unit 63B, and the abnormality identification code is transmitted to the transmission information selection unit 68. Then, in the transmission information selection unit 68 that has received the abnormality identification code, the information selection processing unit 681 compares the abnormality identification code with the transmission information selection table T1 of the table holding unit 682 and transmits data to be transmitted to the remote monitoring server 70. Determined and transmitted to the modem 65 from the abnormal time data storage unit 63B (various signals and information of the outdoor units 20a and 20b, the indoor units 10a and 10b, and the total heat exchange units 40a and 40b at the time of abnormality) ). Therefore, in this remote monitoring system 150, it is possible to omit the transmission of accumulated data at the time of abnormality that is not related to the identification of the cause of the abnormality. Therefore, the remote monitoring system 150 can quickly identify the cause of the abnormality and perform a quick repair service while keeping the communication cost low.

(2)
In the remote monitoring system 150 according to the present embodiment, a transmission information selection table is created in the table creation program 73f of the remote monitoring server 70, and when the transmission information selection table is transmitted to the air conditioning controller 60 by the modem 77, the air conditioning controller In 60, the table update unit 69 updates the transmission information selection table. For this reason, in the remote monitoring system 150, for example, the contents of the transmission information selection table can be easily changed in accordance with a change in season or the like.

(3)
In the remote monitoring system 150 according to the present embodiment, the transmission information selection table can be optimized for each of the buildings 101, 102, and 103 (for example, a certain building is installed in a warm region and a certain building is in a cold region). In such a case, the transmission information selection table can be optimized in consideration of such a building environment). Therefore, in this remote monitoring system 150, it is possible to omit transmission of accumulated data at the time of abnormality that is not related to specification of the cause of abnormality for each of the buildings 101, 102, and 103. Therefore, in this remote monitoring system, it is possible to quickly identify the cause of abnormality and perform a quick repair service while further reducing the communication cost.

(4)
In the remote monitoring system 150 according to the present embodiment, the transmission information selection unit 68 filters the abnormal accumulation data so that the abnormal accumulation data of a specific data item is transmitted to the remote monitoring server 70. For this reason, in this remote monitoring system 150, it is possible to omit transmission of abnormal accumulation data corresponding to unnecessary items in the abnormal accumulation data. Therefore, in this remote monitoring system, it is possible to quickly identify the cause of the abnormality and perform a quick repair service while keeping the communication cost low.

[Modification]
(A)
In the remote monitoring system 150 according to the previous embodiment, the transmission information selection table T1 in which only data that needs to be transmitted to the remote monitoring server 70 is selected for each abnormality identification code is used. Thus, a transmission information selection table as shown in FIG. 10 may be adopted. If this transmission information selection table is adopted, if high pressure abnormality occurs and the compressor inverter frequency is higher than 45 Hz, not only high pressure data but also compressor inverter frequency data and discharge pipe temperature data are monitored remotely. Although it will be transmitted to the server 70, when the compressor inverter frequency is 45 Hz or less, only the high pressure data is transmitted to the remote monitoring server 70. For this reason, in this remote monitoring system 150, the correspondence between the abnormality identification code and the necessary accumulated data at the time of abnormality can be set more finely.

(B)
In the remote monitoring system 150 according to the previous embodiment, the transmission information selection table T1 in which only data that needs to be transmitted to the remote monitoring server 70 is selected for each abnormality identification code is used. Thus, a transmission information selection table as shown in FIG. 11 may be adopted. In this transmission information selection table, when a high pressure abnormality occurs, high pressure data for 20 minutes is generated, when a discharge pipe temperature abnormality occurs, the discharge pipe temperature for 30 minutes and a low pressure abnormality occur. In this case, the low pressure data for 15 minutes is set to be transmitted to the remote monitoring server 70. For this reason, in this remote monitoring system 150, it is possible to omit transmission of accumulated data at the time of abnormality that is unnecessary for quickly identifying the cause of the abnormality.

(C)
In the remote monitoring system 150 according to the previous embodiment, the transmission information selection unit 68 and the table update unit 69 are arranged in the air conditioning controller 60. However, the transmission information selection unit 68 and the table update unit 69 are connected to the remote monitoring server 70. It does not matter if it is deployed in In such a case, the air conditioning controller 60 requires a data filtering unit that filters the abnormal accumulation data specified by the transmission information selection unit 68 of the remote monitoring server 70.

(D)
Although not particularly shown in the remote monitoring system 150 according to the previous embodiment, after the remote monitoring server 70 receives the accumulated data at the time of abnormality, the necessary accumulated data at the time of abnormality is confirmed and the air conditioning controller 60 is checked. The remote monitoring server 70 may be provided with a function of additionally ordering the abnormal accumulated data.

  The remote monitoring system according to the present invention is characterized by being able to quickly identify the cause of an abnormality and perform a quick repair service while keeping communication costs low, and is useful for management of equipment and the like.
