<Target problems and criteria>
Next, the predetermined problem of the indoor unit extracted by the air conditioner management device 40 according to the present embodiment, that is, a large amount of power consumption, long-time operation, and a decrease in comfort will be described.
(I) High power consumption High power consumption means that the power consumption value is large. The air conditioner management device 40 determines a reference value for heavy power consumption, extracts the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... That have consumed an amount of power that exceeds the reference value. Display in order of power consumption value. In the case where the power consumption value is corrected by the correction unit 34e, the order is determined based on the value corrected by the correction unit 34e.
　本実施形態において、空調機管理装置４０は、電力多消費の室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・を判定するための基準値を、式：ｙ＝ｋ・ａ・ｘを用いて決定する。ここで、ｙは、電力消費量値の所定期間における基準値、ｘは、運転時間の期間平均値、ｋは抽出条件を設定する際に決定した所定の値、ａは平均電力の傾きである。平均電力は、各室内機の電力消費量値の期間平均値および運転時間の期間平均値について最小二乗法を用いて算出した近似直線としている。なお、電力消費量値の期間平均値を、ｙ（ｉ）［ｉ＝１，２，．．．ｎ（ｎ：室内機の数）］、運転時間の期間平均値を、ｘ（ｉ）［ｉ＝１，２，．．．ｎ（ｎ：室内機の数）］とした時、近似曲線は、ｙ＝ａ・ｘで表され、傾きａは、２乗誤差を最小にする下記の式から求められる。 In this embodiment, the air conditioner management device 40 uses a reference value for determining the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,.

　（ｉｉ）長時間運転
　長時間運転とは、一日あたりの積算運転時間が所定の判定値を超える運転を意味する。所定の判定値とは、ユーザによって設定される所定の値である。本実施形態においては、空調機管理装置４０は、集計対象期間において、長時間運転の発生日数が１日以上の室内機を抽出し、さらに抽出した室内機を長時間運転の発生日数が多い順番に表示する。長時間運転の発生日数の算出方法は、図３に示すように、まず、１日の積算運転時間［時間］を算出し（ステップＳ１）、次に、積算運転時間が所定の判定値以上であるかを判断する（ステップＳ２）。その後、ステップＳ２において、積算運転時間が判定値以上である場合に、長時間運転の発生日数に１日が加算される。ステップＳ２において、積算運転時間が判定値より少ない場合には、日数は加算されない。 (Ii) Long-time operation The long-time operation means an operation in which the accumulated operation time per day exceeds a predetermined determination value. The predetermined determination value is a predetermined value set by the user. In the present embodiment, the air conditioner management device 40 extracts the indoor units in which the long-time operation occurrence days are one day or more in the counting target period, and further extracts the extracted indoor units in the order in which the long-time operation occurrence days are large. To display. As shown in FIG. 3, the method for calculating the number of days in which long-time operation has occurred first calculates the accumulated operation time [hour] of the day (step S1), and then the accumulated operation time is equal to or greater than a predetermined determination value. It is determined whether or not there is (step S2). Thereafter, in step S2, one day is added to the number of days of long-time operation when the accumulated operation time is equal to or greater than the determination value. In step S2, if the accumulated operation time is less than the determination value, the number of days is not added.
　（ｉｉｉ）快適性低下
　快適性低下とは、室内機で設定した温度に吸込温度が到達しない場合であって、一時間あたりの吸込温度の平均値と、一時間あたりの設定温度の平均値との乖離値が所定の判定値以上である状態をいう。本実施形態においては、空調機管理装置４０は、集計対象期間において、快適性低下の状態が１時間以上あった室内機を抽出し、さらに、抽出した室内機を快適性低下状態にある時間が長い順番に表示する。なお、上述の補正部３４ｅによる補正があった場合には、補正部３４ｅによって補正された値に基づいてこの順番が決定される。快適性低下の時間の算出方法は、図４に示すように、まず、サーモオン時間が６０分以上続いているかが判断される（ステップＳ１１）。サーモオン時間が６０分以上続いている場合は、吸込温度が設定温度に到達していない状態が６０分以上続いていることを意味する。ステップＳ１１において、サーモオン時間が６０分以上続いている場合には、吸込温度と設定温度との差が、所定の判定値以上であるか否かが判断される（ステップＳ１２）。ステップＳ１２において、吸込温度と設定温度との差が、判定値以上であった場合には、快適性低下時間に１時間を加算する（ステップＳ１３）。 (Iii) Deterioration in comfort Deterioration in comfort is when the suction temperature does not reach the temperature set in the indoor unit, and the average value of the suction temperature per hour and the average value of the set temperature per hour This means that the deviation value is equal to or greater than a predetermined determination value. In the present embodiment, the air conditioner management device 40 extracts indoor units that have been in a state of reduced comfort for 1 hour or more during the counting target period, and further, the time during which the extracted indoor units are in a state of reduced comfort. Display in long order. In addition, when correction | amendment by the above-mentioned correction | amendment part 34e has been performed, this order is determined based on the value correct | amended by the correction | amendment part 34e. As shown in FIG. 4, in the method of calculating the comfort reduction time, first, it is determined whether the thermo-on time continues for 60 minutes or more (step S11). When the thermo-on time continues for 60 minutes or more, it means that the state where the suction temperature does not reach the set temperature continues for 60 minutes or more. In step S11, when the thermo-on time continues for 60 minutes or more, it is determined whether or not the difference between the suction temperature and the set temperature is equal to or greater than a predetermined determination value (step S12). In step S12, when the difference between the suction temperature and the set temperature is equal to or greater than the determination value, 1 hour is added to the comfort reduction time (step S13).

　＜特徴＞
　（１）本実施形態において例示したオフィスビル等のように、複数の室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・を含むマルチタイプの空調機が複数設置されている場合、室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・の運転状況を把握する管理者は、各室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・の情報が集められる空調機管理装置４０で全ての室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・の情報を確認することになる。この時、例えば、室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・が効率よく動いているか、あるいは、無駄な運転がされていないか等を確認するため、室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・の一つ一つを確認するには、相当な時間と労力を要する。 On the setting screen, there are a part (reference numeral 1001) for inputting the date of the target period, and a part (reference numeral 1002a-1002c) for selecting the target indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,. In addition, there are provided a change point (reference numeral 1003) of the determination condition for heavy power consumption, a change position (reference numeral 1004) of the determination condition for long-time driving, and a change position (reference numeral 1005) of the determination condition for comfort reduction. The target indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... Are selected (reference numerals 1002a-1002c), and the indoor units to be extracted can be registered as a group, and the indoor units 12aa- The condition for problem extraction can be set for each group of 12ad, 12ba-12bd, 12ca-12cd,.
<Features>
(1) When a plurality of multi-type air conditioners including a plurality of indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... Are installed as in the office building illustrated in the present embodiment, An administrator who grasps the operation status of the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... Collects information on each indoor unit 12aa-12ad, 12ba-12bd, 12ca-12cd,. The air conditioner management device 40 confirms information on all the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,. At this time, for example, in order to confirm whether the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... Are operating efficiently or if a useless operation is not performed, the indoor units 12aa-12ad , 12ba-12bd, 12ca-12cd,..., Require considerable time and labor.
　しかし、本実施形態に係る空調機管理システムでは、空調機管理装置４０が所定の問題、すなわち、電力多消費、長時間運転、および快適性低下の３つの指標に基づき、判定基準を設け、当該判定基準を上回る室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・を抽出して表示する抽出画面を生成する。この抽出画面では、対象となっている全室内機２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・の抽出結果を表示するため、全体的に問題を把握することができる。これにより、確認すべき室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・を限定することができる。また、空調機管理装置４０は、３つの指標に基づいて抽出された室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・の詳細情報を表示する詳細画面を生成する。これにより、一の室内機の対象期間における問題発生の状況を詳細に確認することができる。さらに、表示切替部３４ｉが、表示部３５に表示される抽出画面を、抽出画面で選択された一の室内機の詳細画面に切り替える。したがって、確認すべき室内機の情報を容易に特定でき、確認するための作業に費やす時間や労力を削減することができる。 However, in the air conditioner management system according to the present embodiment, the air conditioner management device 40 provides a determination criterion based on the predetermined problems, that is, three indicators of heavy power consumption, long-time operation, and reduced comfort, An extraction screen for extracting and displaying the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... Exceeding the determination standard is generated. This extraction screen displays the extraction results of all indoor units 2aa-12ad, 12ba-12bd, 12ca-12cd,. Thereby, the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... To be confirmed can be limited. Further, the air conditioner management device 40 generates a detailed screen that displays detailed information of the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... Extracted based on the three indexes. Thereby, the situation of the problem 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 the one indoor unit selected on the extraction screen. Therefore, it is possible to easily identify the information of the indoor unit to be confirmed, and it is possible to reduce the time and labor required for the work for confirmation.
　（２）本実施形態で例示したオフィスビル等では、複数の室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・で消費された電力量を推定するため、総電力消費量値を按分し、各室内機の電力消費量値を算出する。しかし、電力消費量値の大きい室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・を全て省エネすべき室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・と判断することは妥当ではない。すなわち、必要最低限で使用されている室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・であっても、終日使用される場合と、そうでない場合とでは、電力消費量値は前者の方が大きくなってしまうため、電力消費量値を単純に比較して判断するべきではない。
　しかし、本発明に係る空調機管理装置４０は、各室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・の運転履歴に関するデータおよび運転状態に関するデータを取得し、これらのデータに基づいて、所定期間における一日あたりの電力消費量値が基準値に比べて高い室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・が抽出される。すなわち、設定温度や運転時間等も考慮した結果が抽出されるため、省エネ可能な室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・を容易に特定することができる。 (2) In the office building and the like exemplified in the present embodiment, the total power consumption value is set in order to estimate the power consumed by the plurality of indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,. Prorate and calculate the power consumption value of each indoor unit. However, the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... With large power consumption values are all determined as indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,. That is not valid. That is, even if the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,... That are used at the minimum necessary, the power consumption value is different depending on whether the indoor unit is used all day or not. Since the former is larger, the power consumption value should not be judged simply by comparison.
However, the air conditioner management device 40 according to the present invention obtains data relating to the operation history and data relating to the operation state of each indoor unit 12aa-12ad, 12ba-12bd, 12ca-12cd,. Thus, the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,..., Whose daily power consumption values in the predetermined period are higher than the reference value are extracted. That is, since the results taking into account the set temperature, the operation time, and the like are extracted, it is possible to easily specify the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,.
　さらに、本実施形態に係る空調機管理装置４０は、省エネ可能な室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・を抽出する際に、室内機の空調能力を考慮する。具体的には、省エネ可能な室内機を抽出する際あるいは優先順位をつける際に、運転時間に対して電力消費量値が大きい室内機の優先順位を高くするという補正に加え、各室内機の電力消費量値が、その室内機の定格空調能力に対して大きい場合に、優先順位を高くするという補正を行う。したがって、空調能力の違いを考慮した電力消費量値の比較をすることができる。
　（３）また、本実施形態に係る空調機管理装置４０は、快適性低下として判断された室内機１２ａａ－１２ａｄ，１２ｂａ－１２ｂｄ，１２ｃａ－１２ｃｄ，・・・に関し、上述したように、快適性低下の発生率で補正した値に基づいて抽出結果を表示することができる。例えば、一日あたりの平均運転時間が８時間である場合に、快適性低下として判断された時間の平均が３時間である場合と、一日あたりの平均運転時間が４時間である場合に、快適性低下として判断された時間の平均が２時間である場合とでは、後者の方が問題の程度が大きい。したがって、発生率で補正した値に基づいて抽出結果を表示することにより、実質的に問題の程度が大きい室内機を上位に挙げることができる。 Further, the air conditioner management apparatus 40 according to the present embodiment considers the air conditioning capability of the indoor units when extracting the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,. Specifically, when extracting or setting priorities for indoor units that can save energy, in addition to the correction of increasing the priority of indoor units with large power consumption values relative to the operating time, When the power consumption value is larger than the rated air conditioning capacity of the indoor unit, a correction is made to increase the priority. Therefore, it is possible to compare the power consumption values considering the difference in air conditioning capability.
(3) In addition, the air conditioner management device 40 according to the present embodiment relates to the indoor units 12aa-12ad, 12ba-12bd, 12ca-12cd,. The extraction result can be displayed based on the value corrected with the occurrence rate of the decrease. For example, when the average driving time per day is 8 hours, when the average time determined as a decrease in comfort is 3 hours, and when the average driving time per day is 4 hours, In the case where the average time determined as a decrease in comfort is 2 hours, the latter is more problematic. Therefore, by displaying the extraction result based on the value corrected by the occurrence rate, it is possible to list indoor units that have a substantially large problem.
