To check the information of all indoor units (12aa-12ad, 12ba-12bd, 12ca-12cd,…). At this time, for example, in order to check whether the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd, ... are moving efficiently or are not in unnecessary use, etc., the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd, ...) requires a great deal of time and effort.

However, in the air conditioner management system according to the present embodiment, the air conditioner management device 40 sets the determination criteria based on three indicators of a predetermined problem, namely power consumption, long time operation, and reduced comfort. And an extraction screen for extracting and displaying the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd, ... that exceed the determination criteria. This extraction screen displays the extraction results of all indoor units 2aa-12ad, 12ba-12bd, 12ca-12cd, ... that are the target, so that the problem can be grasped as a whole. Thereby, the indoor unit 12aa-12ad, 12ba-12bd, 12ca-12cd, ... which should be confirmed can be limited. Moreover, the air conditioner management apparatus 40 produces | generates the detail screen which displays the detailed information of the indoor unit 12aa-12ad, 12ba-12bd, 12ca-12cd, ... extracted based on three index | index. Thereby, the situation of the trouble occurrence in the target period of one indoor unit can be confirmed in detail. Further, the display switching unit 34i switches the extraction screen displayed on the display unit 35 to the detail screen of one indoor unit selected from the extraction screen. Therefore, the information of the indoor unit to be confirmed can be easily specified, and the time and effort spent on the work for confirmation can be reduced.

(2) In the office buildings and the like exemplified in the present embodiment, since the amount of power consumed by the plurality of indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd, ... is estimated, the total power consumption value is subdivided. The power consumption value of the indoor unit is calculated. However, it is reasonable to judge all indoor units (12aa-12ad, 12ba-12bd, 12ca-12cd,…) that have large power consumption values as indoor units (12aa-12ad, 12ba-12bd, 12ca-12cd,…) that need energy saving. Not. In other words, even when the indoor units (12aa-12ad, 12ba-12bd, 12ca-12cd, ...) are used at the minimum necessary, the power consumption value is increased when the former is used and when it is not used all day. Do not judge by simply comparing the values.

However, the air conditioner management apparatus 40 which concerns on this invention acquires the data regarding the operation | movement history of each indoor unit 12aa-12ad, 12ba-12bd, 12ca-12cd, ..., and the data regarding a driving state, and these data Based on this, indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd, ... having a higher power consumption value per day in a predetermined period than the reference value are extracted. That is, since the result which also considers the set temperature, the operation time, etc. is taken out, the energy saving indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd, ... can be easily specified.

Furthermore, the air conditioner management apparatus 40 which concerns on a present Example considers the air conditioner capability of an indoor unit when extracting the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd, ... which can save energy. Specifically, when extracting or prioritizing an energy-saving indoor unit, in addition to the correction that the priority of the indoor unit having a large power consumption value with respect to the driving time is increased, the power consumption value of each indoor unit is the indoor unit. If the rated air conditioning capacity is large, correction is made to increase the priority. Therefore, it is possible to compare the power consumption value in consideration of the difference in air conditioning capacity.

(3) In addition, the air conditioner management apparatus 40 which concerns on a present Example is comfortable as mentioned above about the indoor unit 12aa-12ad, 12ba-12bd, 12ca-12cd, ... judged as a comfort fall. The extraction result can be displayed based on the value corrected by the incidence rate of the degradation. For example, when the average driving time per day is 8 hours, when the average of the time determined as the comfort deterioration is 3 hours, and when the average driving time per day is 4 hours, the time determined as the comfort deterioration is determined. In the case where the average is 2 hours, the latter is more problematic. Therefore, by displaying the extraction result based on the value corrected by the incidence rate, it is possible to raise the indoor unit having a substantially high degree of problem.
