- the reference range may be a predetermined fixed value, or may be a variable value that changes appropriately according to the driving situation. For example, weighting is increased for the operating condition in a predetermined period from the start of trial operation, and weighting is gradually reduced for the operating condition after the predetermined period has elapsed, and calculations are performed based on these weightings.

- the standard range of "high pressure” is, for example, “1.0 to 1.5”
- the standard range of "low pressure” is, for example, "1.0 to 1.5”. Since the actual high pressure "1.53" of the refrigeration cycle circuit UC1a is out of the reference range "1.0 to 1.5", the indication of the actual high pressure "1.53" of the refrigeration cycle circuit UC1a is different from the usual display form (dotted points shown) Obviously.

Abstract
Description
図1に示すように、複数(例えば8個)の熱源ユニットUC1,UC2,…UCmが配置されている。熱源ユニットUC1は、複数たとえば4つの冷凍サイクルサーキットUC1a,UC1b,UC1c,UC1dにより構成される。熱源ユニットUC2は、複数たとえば4つの冷凍サイクルサーキットUC2a,UC2b,UC2c,UC2dにより構成される。熱源ユニットUC3は、複数たとえば4つの冷凍サイクルサーキットUC3a,UC3b,UC3c,UC3dにより構成される。熱源ユニットUC4は、複数たとえば4つの冷凍サイクルサーキットUC4a,UC4b,UC4c,UC4dにより構成される。
第1制御セクション41aは、ディスプレイ44へのタッチ操作によって運転状況確認モードが指定された場合に、モジュールコントローラ20に対するデータ要求信号を送受信ユニット45から無線送信する。
モジュールMC1における熱源ユニットUC1~UCmの運転データを確認したいユーザは、タブレット端末40を持ってモジュールMC1の熱源ユニットUC1に近づき、タブレット端末40のディスプレイ44をタッチ操作して確認モードを指定する。
運転状況確認処理において、CPU41は、SDメモリカード21から取込んだ運転データに基づいて図7に示すデータ表示画面200を生成し、生成したデータ表示画面200をディスプレイ44で表示する。データ表示画面200は、一覧表201、トレンドグラフ指定釦202、故障履歴指定釦203、消耗品指定釦204、日時ディスプレイ205、クリップ釦206、運転データタブ211、点検タブ212、レポートタブ213などの表示を含む。
データ表示画面200におけるトレンドグラフ指定釦202がタッチ操作された場合、CPU41は、図8に示すように、熱源ユニットUC1の運転データの時間的変化と時刻との関係を示すトレンドグラフ表示画面300を生成し、生成したトレンドグラフ表示画面300をディスプレイ44で表示する。
トレンドグラフ301で表示されている熱源ユニットUC1の運転データのうち、例えば時刻“12時46分25秒”の時点の運転データの内容(詳細な値など)を確認したい場合、ユーザは、手指をカーソル線301bにタッチしかつそのタッチ位置を適宜にスライドすることによりカーソル線301bを図8に示すようにトレンドグラフ301の時刻“12時46分25秒”に合わせる。そして、ユーザは、手指をカーソル線301bから離す等の確定操作を行う。CPU41は、この確定操作に応じて、トレンドグラフ301で表示している熱源ユニットUC1の運転データのうち、カーソル線301bで指定した時刻“12時46分25秒”の時点の運転データを抽出し、抽出した運転データの内容の文字表示を項目名の文字表示と共に含む図9のユニット別データ表示画面400を生成してそれをディスプレイ44で表示する。
トレンドグラフ表示画面300のレポートタブ213またはユニット別データ表示画面400のレポートタブ213がタッチ操作された場合、CPU41は、カーソル301bで指定された時刻における運転データ(ユニット別データ表示画面400の一覧表401,402で表示される運転データの内容が文字や画像で表わされる業務報告用のレポートファイルを生成し、生成したレポートファイルを図10に示すレポート表示画面(第1レポート表示画面)500と図11に示すレポート表示画面(第2レポート表示画面)600とに分けてディスプレイ44で順次に表示する。
無線通信機能を有するSDメモリカード21をモジュールコントローラ20に後付けする構成なので、各熱源ユニットやモジュールコントローラ20に無線通信機能を持たせる必要がない。よって、各熱源ユニットやモジュールコントローラ20の製造コストを安価にすることができる。機器そのものに無線通信機能を持たせる場合、国毎の電波法に則った認証が必要になるため、機器毎の認証取得コストが必要になるが、本実施形態のように無線通信機能を有するSDメモリカード21を用いることにより、機器毎の電波法関連の認証取得コストを削減することができる。
タブレット端末40は、運転状況確認モードの指定だけでなく、各熱源ユニットの点検作業を実施する場合に、各熱源ユニットにおける外気ファン6およびポンプ8の運転・停止を操作することが可能である。
セキュリティの観点から、表示画面200,300,400,500,600を管理者用の様式とサービスマン用の様式とに分けたい場合、および業務報告レポート700を管理者用の様式とサービスマン用の様式とに分けて生成したい場合、が想定される。
SDメモリカード21は、モジュールコントローラ20から供給される電力で動作する。SDメモリカード21の受信セクション21bの動作は、各熱源ユニットの少なくとも1つが運転状態にある場合は常にオンする。SDメモリカード21の送信セクション21cの動作は、各熱源ユニットの少なくとも1つが運転状態にあってしかもタブレット端末40との通信リンクが成立した場合のみオンする。通信リンクが成立した場合のみ送信セクション21cの動作がオンするので、データの不要な漏洩を回避できるとともに、SDメモリカード21の消費電力を低減できる。
上記実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。
