Description

空調設置支援システムおよびプログラムAir conditioning installation support system and program
　本発明は、空調システムの制御パラメータの設定を支援するシステムに関する。 The present invention relates to a system that supports the setting of control parameters of an air conditioning system.
　空調システムは、室内機と室外機の間を循環する冷媒を介して熱交換を行うことにより冷暖房を行う。ここで、冷媒を圧送する圧縮機や膨張弁の制御パラメータは、室内機と室外機の設置位置の高低差に起因して発生する冷媒の圧力降下を考慮して設定する必要があるが、室内外機の高低差をどのようにして取得するのかが問題となる。 The air conditioning system heats and cools by exchanging heat via the refrigerant that circulates between the indoor unit and the outdoor unit. Here, the control parameters of the compressor and the expansion valve that pump the refrigerant need to be set in consideration of the pressure drop of the refrigerant that occurs due to the height difference between the installation positions of the indoor unit and the outdoor unit. The problem is how to obtain the height difference of the external unit.
　この点につき、特許文献１は、現地作業員が携帯通信端末（スマートデバイス）に搭載される高度センサを用いて室内機と室外機のそれぞれの高さ情報を取得し、２つの高さ情報から取得される高低差情報に基づいて冷媒の搬送能力を設定する空調システムを開示しており、用いられる高度センサとして、ＧＰＳセンサ、地磁気センサ、気圧センサを例示する。 Regarding this point, in Patent Document 1, a local worker acquires height information of each of an indoor unit and an outdoor unit by using an altitude sensor mounted on a mobile communication terminal (smart device), and uses the two height information. An air-conditioning system that sets the refrigerant transfer capacity based on the acquired height difference information is disclosed, and GPS sensors, geomagnetic sensors, and pressure sensors are exemplified as the altitude sensors used.
　しかしながら、ＧＰＳセンサは、屋内に設置される室内機の高さを検出できない場合があり、地磁気センサは、建物周辺の磁力変化によって測定値が影響を受けやすく、気圧センサを用いる方法では、室内外の気圧差が大きい場合に高低差に誤差が生じるという問題がある。 However, the GPS sensor may not be able to detect the height of the indoor unit installed indoors, and the geomagnetic sensor is easily affected by the change in the magnetic force around the building, and the method using the barometric pressure sensor is indoors and outdoors. There is a problem that an error occurs in the height difference when the pressure difference is large.
　加えて、室外機と室内機を接続する冷媒配管が長くなるほど冷媒の圧力損失が増大するが、特許文献１は、この点を何も考慮していない。 In addition, the longer the refrigerant pipe connecting the outdoor unit and the indoor unit, the greater the pressure loss of the refrigerant, but Patent Document 1 does not consider this point at all.

　以上、空調設置支援システム１００の機能構成について説明してきたが、続いて、本実施形態の携帯通信端末１０が実行する処理の内容を図４に示すフローチャートに基づいて説明する。なお、以下の説明においては、適宜、図２を参照するものとする。 The functional configuration of the air conditioner installation support system 100 has been described above, but subsequently, the content of the process executed by the mobile communication terminal 10 of the present embodiment will be described based on the flowchart shown in FIG. In the following description, FIG. 2 will be referred to as appropriate.
　現地作業員が携帯通信端末１０にインストールされた専用アプリを起動すると、これを受けて、まず最初に、配管モデル取得部１２が、携帯通信端末１０のディスプレイ画面に図５（ａ）に示す配管モデル選択画面を表示する（ステップ１０１）。 When the local worker activates the dedicated application installed on the mobile communication terminal 10, in response to this, the piping model acquisition unit 12 first displays the piping shown in FIG. 5A on the display screen of the mobile communication terminal 10. The model selection screen is displayed (step 101).
　このとき、配管モデル選択画面には、「配管モデルを選択してください」というメッセージとともに、配管モデルのサムネイルがタイル状に並んで選択可能に表示される。これを受けて、現地作業員が表示された複数のサムネイルの中から現地の空調機のレイアウトに合致する配管モデルのサムネイルを選択すると、配管モデル取得部１２は、選択されたサムネイルに対応する配管モデルを記憶領域１７に保存される配管モデルのライブラリから取得する（ステップ１０２）。 At this time, on the piping model selection screen, the thumbnails of the piping models are arranged in tiles and can be selected with the message "Please select the piping model". In response to this, when the local worker selects a piping model thumbnail that matches the layout of the local air conditioner from the plurality of thumbnails displayed, the piping model acquisition unit 12 selects the piping corresponding to the selected thumbnail. The model is acquired from the piping model library stored in the storage area 17 (step 102).
　続いて、配管パラメータ取得部１３は、携帯通信端末１０のディスプレイ画面に図５（ｂ）に示す空調機番号入力画面を表示する（ステップ１０３）。 Subsequently, the piping parameter acquisition unit 13 displays the air conditioner number input screen shown in FIG. 5B on the display screen of the mobile communication terminal 10 (step 103).
　このとき、空調機番号入力画面には、「空調機を選択して空調機番号を入力してください」というメッセージとともに、先に選択された配管モデルの画像が表示される。このとき表示される画像において、□（室外機を表す）および○（室内機を表す）は、それぞれが空調機番号の入力を受け付けるためのアイコンとして機能し、これらのアイコンを選択すると、ソフトウェアキーボード（図示せず）が表示され、空調機番号を入力できるようになっている。なお、ここでいう空調機番号とは、空調システム内で空調機（室外機、室内機）を一意に識別する識別情報を意味し、空調機の製造番号（シリアル番号）を例示することができる。 At this time, the image of the piping model selected earlier is displayed on the air conditioner number input screen along with the message "Please select an air conditioner and enter the air conditioner number". In the image displayed at this time, □ (representing the outdoor unit) and ○ (representing the indoor unit) each function as an icon for accepting the input of the air conditioner number, and when these icons are selected, the software keyboard (Not shown) is displayed and the air conditioner number can be entered. The air conditioner number referred to here means identification information that uniquely identifies the air conditioner (outdoor unit, indoor unit) in the air conditioning system, and the serial number of the air conditioner can be exemplified. ..
　現地作業員が、上述した手順で、配管モデルを構成する全ての空調機（室外機、室内機）の空調機番号の入力を終えると、携帯通信端末１０のディスプレイ画面は、図５（ｂ）に示す空調機番号設定画面に遷移する。 When the local worker finishes inputting the air conditioner numbers of all the air conditioners (outdoor unit, indoor unit) constituting the piping model by the above procedure, the display screen of the mobile communication terminal 10 is displayed in FIG. 5 (b). Transit to the air conditioner number setting screen shown in.
　このとき、空調機番号設定画面には、「以下の空調機番号を設定します」というメッセージとともに、入力された空調機番号が空調機のアイコンの横に表示される。これを受けて、現地作業員がＯＫボタンを押下すると、配管パラメータ取得部１３が、先のステップ１０２で取得した配管モデルの構成要素である各空調機（室外機、室内機）に対して入力された空調機番号を設定する（ステップ１０４）。 At this time, on the air conditioner number setting screen, the entered air conditioner number is displayed next to the air conditioner icon along with the message "Set the following air conditioner numbers". In response to this, when the local worker presses the OK button, the piping parameter acquisition unit 13 inputs to each air conditioner (outdoor unit, indoor unit) which is a component of the piping model acquired in the previous step 102. The set air conditioner number is set (step 104).
　空調機番号の設定が終わると、配管パラメータ取得部１３が、携帯通信端末１０のディスプレイ画面に図６（ａ）に示す配管パラメータ設定画面を表示する（ステップ１０５）。 When the setting of the air conditioner number is completed, the piping parameter acquisition unit 13 displays the piping parameter setting screen shown in FIG. 6A on the display screen of the mobile communication terminal 10 (step 105).
　このとき、配管パラメータ設定画面には、「配管を選択してください」というメッセージとともに、先に選択された配管モデルの画像が表示される。このとき表示される画像において、太線で示すリンクは、配管パラメータの入力を受け付けるためのアイコンとして機能するようになっている。 At this time, the image of the previously selected piping model is displayed on the piping parameter setting screen along with the message "Please select a piping". In the image displayed at this time, the link shown by the thick line functions as an icon for accepting the input of the piping parameter.
　現地作業員が配管パラメータを設定しようとする配管に対応するリンク（アイコン）を選択してタップし、ＯＫボタンを押下すると（ステップ１０６、Ｙｅｓ）、これに応答して、画像測距部１４（測距用アプリケーション）が起動し（ステップ１０７）、これに伴って、携帯通信端末１０のディスプレイ画面は、図６（ｂ）に示す画像測距アプリ画面に遷移する。 When the local worker selects and taps the link (icon) corresponding to the pipe for which the pipe parameter is to be set and presses the OK button (step 106, Yes), in response to this, the image distance measuring unit 14 ( The distance measurement application) is activated (step 107), and the display screen of the mobile communication terminal 10 transitions to the image distance measurement application screen shown in FIG. 6B.
　画像測距アプリ画面が表示されたことを受けて、現地作業員は、携帯通信端末１０に搭載されるカメラで空調機の設置環境を撮影して測距を実行する。ここで、現地作業員が実行する作業を図７に基づいて具体的に説明する。例えば、ビル２００の屋外の地面に設置される室外機２０と５Ｆに設置される室内機３０（１）を接続する配管の長さを計測しようとする場合、現地作業員は、携帯通信端末１０のカメラでビル２００を外から撮影しながら、画像測距アプリ画面に表示される撮影画像上において、室外機２０にポインターを合わせた後に、ビル２００の５Ｆの窓越しに見える室内機３０（１）にポインターを合わせる。これにより、室外機２０と室内機３０（１）の離間距離が測定される。一方、ビル２００の５Ｆの天井に設置される室内機３０（１）と室内機３０（２）を接続する配管の長さを計測しようとする場合には、現地作業員は、ビル２００の５Ｆに移動して、携帯通信端末１０のカメラで５Ｆの天井を撮影しながら、画像測距アプリ画面に表示される撮影映像上において、室内機３０（１）にポインターを合わせた後に、室内機３０（２）にポインターを合わせる。これにより、室内機３０（１）と室内機３０（２）の離間距離が測定される。 In response to the display of the image distance measurement application screen, the local worker photographs the installation environment of the air conditioner with the camera mounted on the mobile communication terminal 10 and executes distance measurement. Here, the work performed by the local worker will be specifically described with reference to FIG. For example, when trying to measure the length of the pipe connecting the outdoor unit 20 installed on the outdoor ground of the building 200 and the indoor unit 30 (1) installed on the 5th floor, the local worker may use the mobile communication terminal 10. The indoor unit 30 (1) that can be seen through the window on the 5th floor of the building 200 after pointing the pointer at the outdoor unit 20 on the captured image displayed on the image ranging application screen while shooting the building 200 from the outside with the camera of ) To the pointer. As a result, the separation distance between the outdoor unit 20 and the indoor unit 30 (1) is measured. On the other hand, when trying to measure the length of the pipe connecting the indoor unit 30 (1) and the indoor unit 30 (2) installed on the ceiling of the 5th floor of the building 200, the local worker is on the 5th floor of the building 200. Move to, and while shooting the ceiling on the 5th floor with the camera of the mobile communication terminal 10, move the pointer to the indoor unit 30 (1) on the captured image displayed on the image ranging application screen, and then move to the indoor unit 30. Place the pointer on (2). As a result, the separation distance between the indoor unit 30 (1) and the indoor unit 30 (2) is measured.
　再び、図４に戻って説明を続ける。 Returning to Fig. 4 again, the explanation is continued.
　配管パラメータ設定画面上で選択した配管に関して、画像測距アプリ画面を介した測距が終了すると、これに応答して、配管パラメータ取得部１３が、先のステップ１０２で取得した配管モデルの構成要素である複数の配管のうち、当該選択した配管の長さとして、画像測距部１４の測距結果を設定する（ステップ１０８）。 When the distance measurement via the image distance measurement application screen is completed for the pipe selected on the piping parameter setting screen, the piping parameter acquisition unit 13 responds to this and the component of the piping model acquired in the previous step 102. The distance measurement result of the image distance measurement unit 14 is set as the length of the selected pipe among the plurality of pipes (step 108).
　選択した配管の配管パラメータの設定が終わると、携帯通信端末１０のディスプレイ画面は、再び、画像パラメータ設定画面に戻る。このとき、画像パラメータ設定画面には、図６（ｃ）に示すように、選択された配管に対応するリンク（アイコン）の上に設定された配管パラメータ（配管の長さ）が表示される。 When the setting of the piping parameters of the selected piping is completed, the display screen of the mobile communication terminal 10 returns to the image parameter setting screen again. At this time, as shown in FIG. 6C, the piping parameter (pipe length) set on the link (icon) corresponding to the selected pipe is displayed on the image parameter setting screen.
　その後、現地作業員は、画像パラメータ設定画面上で配管を選択してから、画像測距アプリ画面を介して選択した配管の長さを測距する、という一連の作業を繰り返す。 After that, the local worker repeats a series of operations of selecting the pipe on the image parameter setting screen and then measuring the length of the selected pipe via the image distance measurement application screen.
　上述した一連の作業を繰り返した結果、先のステップ１０２で取得した配管モデルを構成する全ての配管の配管パラメータが設定されると（ステップ１０９、Ｙｅｓ）、これに応答して、配管情報生成部１５が、空調機番号と配管パラメータが設定された配管モデルに基づいて配管情報を生成する。具体的には、配管情報生成部１５は、空調機番号と配管パラメータ（配管の長さ）が設定された配管モデルが定義する内容を空調機の制御手段が判読可能なデータ形式に変換し、変換後のデータを配管情報として記憶領域１８に保存する。 As a result of repeating the above-mentioned series of operations, when the piping parameters of all the piping constituting the piping model acquired in the previous step 102 are set (step 109, Yes), in response to this, the piping information generator 15 generates piping information based on a piping model in which an air conditioner number and piping parameters are set. Specifically, the piping information generation unit 15 converts the contents defined by the piping model in which the air conditioner number and the piping parameters (pipe length) are set into a data format that can be read by the control means of the air conditioner. The converted data is stored in the storage area 18 as piping information.
　以上、本実施形態の携帯通信端末１０が実行する処理について説明してきたが、続いて、携帯通信端末１０が生成した配管情報に基づく室外機２０の制御について説明する。 The process executed by the mobile communication terminal 10 of the present embodiment has been described above. Next, the control of the outdoor unit 20 based on the piping information generated by the mobile communication terminal 10 will be described.
　上述した一連の手順を経て、対象となる空調システムの配管情報が生成されると、現地作業員は、携帯通信端末１０を操作して、携帯通信端末１０と室外機２０の間の通信を確立する。これに応答して、携帯通信端末１０の配管情報提供部１６は、記憶領域１８から配管情報を読み出し、読み出した配管情報を室外機２０に送信する。なお、本実施形態では、携帯通信端末１０から室内機３０に配管情報を送信し、当該室内機３０が信号線６０を介して室外機２０に配管情報を転送するようにしてもよいし、携帯通信端末１０から集中機４０に配管情報を送信し、当該集中機４０が信号線６０を介して室外機２０に配管情報を転送するようにしてもよい。 When the piping information of the target air conditioning system is generated through the series of procedures described above, the local worker operates the mobile communication terminal 10 to establish communication between the mobile communication terminal 10 and the outdoor unit 20. To do. In response to this, the piping information providing unit 16 of the mobile communication terminal 10 reads the piping information from the storage area 18 and transmits the read piping information to the outdoor unit 20. In the present embodiment, the mobile communication terminal 10 may transmit the piping information to the indoor unit 30, and the indoor unit 30 may transfer the piping information to the outdoor unit 20 via the signal line 60. The communication terminal 10 may transmit the piping information to the centralizing unit 40, and the centralizing unit 40 may transfer the piping information to the outdoor unit 20 via the signal line 60.
　携帯通信端末１０から配管情報を受信した室外機２０の制御部２２は、受信した配管情報に基づいて制御対象の制御パラメータを導出する。なお、ここでいう制御パラメータとしては、圧縮機の回転数、ファンの回転数、膨張弁の開度などを例示することができる。 The control unit 22 of the outdoor unit 20 that has received the piping information from the mobile communication terminal 10 derives the control parameters to be controlled based on the received piping information. As the control parameters referred to here, the rotation speed of the compressor, the rotation speed of the fan, the opening degree of the expansion valve, and the like can be exemplified.
　制御部２２は、まず、受信した配管情報に基づいて、室外機２０と室内機３０の高低差ならびにこれらを接続する配管の合計長を算出する。なお、室外機２０に複数の室内機３０が接続される場合は、室外機２０と鉛直方向に最も離間する室内機３０との高低差（すなわち、最大の高低差）を算出することが好ましい。さらに、室外機２０に接続される複数の室内機３０のそれぞれの発停状態（運転／停止）を信号線６０を介してリアルタイムに検知して、運転中の室内機３０に関して高低差ならびに配管の合計長を算出することが好ましい。 First, the control unit 22 calculates the height difference between the outdoor unit 20 and the indoor unit 30 and the total length of the pipes connecting them based on the received piping information. When a plurality of indoor units 30 are connected to the outdoor unit 20, it is preferable to calculate the height difference (that is, the maximum height difference) between the outdoor unit 20 and the indoor unit 30 that is most separated in the vertical direction. Further, the start / stop state (operation / stop) of each of the plurality of indoor units 30 connected to the outdoor unit 20 is detected in real time via the signal line 60, and the height difference and the piping of the indoor unit 30 during operation are detected. It is preferable to calculate the total length.
　室内外機の高低差および配管の合計長の算出が終わると、制御部２２は、算出した値を所定の計算式に入力し、その出力として制御パラメータの目標値を導出する。ここでいう計算式とは、室内外機の高低差および配管の合計長を説明変数とし、室内外機の高低差および配管の長さに起因して発生する冷媒の圧力降下の影響を相殺する制御パラメータの目標値を目的変数とする重回帰式を意味する。なお、このような計算式は、同様の機能を果たすルックアップテーブルで代替することもできる。 When the calculation of the height difference of the indoor / outdoor unit and the total length of the pipes is completed, the control unit 22 inputs the calculated value into a predetermined calculation formula and derives the target value of the control parameter as the output. The calculation formula referred to here uses the height difference of the indoor / outdoor unit and the total length of the pipes as explanatory variables, and cancels out the influence of the pressure drop of the refrigerant caused by the height difference of the indoor / outdoor unit and the length of the pipe. It means a multiple regression equation with the target value of the control parameter as the objective variable. Note that such a calculation formula can be replaced by a look-up table that performs the same function.
　各制御パラメータの目標値の導出が終わると、制御部２２は、導出した制御パラメータ（圧縮機の回転数、ファンの回転数、膨張弁の開度など）の目標値に基づいて各制御対象を制御する。 After the derivation of the target value of each control parameter is completed, the control unit 22 sets each control target based on the target value of the derived control parameter (compressor rotation speed, fan rotation speed, expansion valve opening, etc.). Control.
　以上、説明したように、本実施形態によれば、配管仕様が不明な設置現場であっても、予め用意された配管モデルに対して、カメラを用いた測距手段による正確な計測値（室内外機の高低差、配管長）を設定することにより、その場で確度の高い配管情報を取得することができる。また、配管長の情報が制御に供されることにより、室内外機の高低差に起因する冷媒の圧力損失だけでなく、配管長に起因する冷媒の圧力損失をも考慮に入れた最適な空調制御が実現される。 As described above, according to the present embodiment, even at an installation site where the piping specifications are unknown, accurate measurement values (indoors) by a distance measuring means using a camera are obtained for a piping model prepared in advance. By setting the height difference of the external unit and the piping length), it is possible to acquire highly accurate piping information on the spot. In addition, since the information on the pipe length is used for control, optimum air conditioning takes into consideration not only the pressure loss of the refrigerant caused by the height difference between the indoor and outdoor units but also the pressure loss of the refrigerant caused by the pipe length. Control is realized.
　以上、本発明について実施形態をもって説明してきたが、本発明は上述した実施形態に限定されるものではなく、種々の設計変更が可能である。以下、この点を具体的に説明する。 Although the present invention has been described above with the embodiments, the present invention is not limited to the above-described embodiments, and various design changes are possible. Hereinafter, this point will be specifically described.
　上述した実施形態では、配管モデル取得部１２が、携帯通信端末１０の記憶手段から配管モデルを読み出す態様を示したが、別の実施形態では、管理サーバ８０に配管モデルのライブラリを格納し、配管モデル取得部１２が、管理サーバ８０から所望の配管モデルをダウンロードするようにしてもよい。 In the above-described embodiment, the piping model acquisition unit 12 reads out the piping model from the storage means of the mobile communication terminal 10. However, in another embodiment, the management server 80 stores the piping model library and pipes. The model acquisition unit 12 may download a desired piping model from the management server 80.
　上述した実施形態では、配管モデル取得部１２が、予め用意された配管モデルのライブラリの中から所望の配管モデルを取得する態様を示したが、別の実施形態では、配管モデル取得部１２が、携帯通信端末１０が管理サーバ８０から配管設計図やレイアウト情報をダウンロードし、これらの情報に基づいて配管モデルを自動生成するようにしてもよい。 In the above-described embodiment, the piping model acquisition unit 12 has shown an aspect of acquiring a desired piping model from a library of piping models prepared in advance, but in another embodiment, the piping model acquisition unit 12 has The mobile communication terminal 10 may download the piping design drawing and layout information from the management server 80, and automatically generate a piping model based on the information.
　また、別の実施形態では、配管モデルを編集するためのウィザードを提供し、現地作業員が、実際の設置状況に合わせて配管モデルを自由に編集できるようしてもよい。 Further, in another embodiment, a wizard for editing the piping model may be provided so that the local worker can freely edit the piping model according to the actual installation situation.
　また、別の実施形態では、配管パラメータ取得部１３が、配管パラメータとして、配管長に加えて、配管の配管径を取得するようにしてもよい。この場合、現地作業員が、携帯通信端末１０のカメラで、工事中のむきだしの配管や天井裏の配管を撮影し、上述したのと同様の手順で、画像測距アプリ画面を介して配管径を測定したことを受けて、配管パラメータ取得部１３が、その測定値を配管径として配管モデルに設定し、配管情報生成部１５が、室内外機の高低差、配管長、配管径を含む配管情報を生成する。この場合、携帯通信端末１０は、配管情報に含まれる配管長と配管径に基づいて推奨する冷媒充填量を算出することができ、算出した冷媒充填量は、携帯通信端末１０のディスプレイに表示したり、室外機２０の自動充填機の制御パラメータとして用いたりすることができる。 Further, in another embodiment, the piping parameter acquisition unit 13 may acquire the piping diameter of the piping in addition to the piping length as the piping parameter. In this case, a local worker photographs the exposed pipes under construction and the pipes behind the ceiling with the camera of the mobile communication terminal 10, and uses the same procedure as described above to take a picture of the pipe diameter via the image ranging application screen. In response to the measurement, the piping parameter acquisition unit 13 sets the measured value as the piping diameter in the piping model, and the piping information generation unit 15 sets the piping including the height difference of the indoor / outdoor unit, the piping length, and the piping diameter. Generate information. In this case, the mobile communication terminal 10 can calculate the recommended refrigerant filling amount based on the pipe length and the pipe diameter included in the piping information, and the calculated refrigerant filling amount is displayed on the display of the mobile communication terminal 10. Alternatively, it can be used as a control parameter of the automatic filling machine of the outdoor unit 20.
　圧縮機の摺動部に充填される潤滑油は冷媒とともに冷媒回路を循環する過程で、その一部が冷媒回路に滞留するため、これを定期的に回収する必要がある。この点につき、別の実施形態では、室外機２０の制御部２２が、上述した配管情報に基づいて潤滑油回収運転を制御するようにしてもよい。ここで、潤滑油の回収に必要な運転時間は潤滑油の滞留量に依存し、潤滑油の滞留量は配管長に依存するが、配管情報には配管長の情報が含まれているので、配管長の情報に基づいて必要な運転時間を算出することができる。 The lubricating oil filled in the sliding part of the compressor circulates in the refrigerant circuit together with the refrigerant, and a part of it stays in the refrigerant circuit, so it is necessary to collect it regularly. In this regard, in another embodiment, the control unit 22 of the outdoor unit 20 may control the lubricating oil recovery operation based on the above-mentioned piping information. Here, the operating time required for recovering the lubricating oil depends on the amount of the lubricating oil staying, and the amount of the lubricating oil staying depends on the pipe length. However, since the piping information includes the information on the pipe length, The required operating time can be calculated based on the information on the pipe length.
　上述した実施形態では、配管パラメータ取得部１３が画像測距部１４と連動して配管パラメータを取得する態様を示したが、別の実施形態では、現地作業員によって手入力された入力値に基づいて配管パラメータを取得するようにしてもよい。この場合、現地作業員は、例えば、携帯通信端末１０に標準搭載される高度センサの測定値に基づいて室内外機の高低差を計算して、その値を携帯通信端末１０が提供する入力フォームを介して手入力する。なお、高度センサを用いる測定方法では、携帯通信端末１０の位置から室内機が設置される天井までの距離の分だけ高低差に誤差が生じるので、これについては、携帯通信端末１０のＡＲメジャー機能を利用して測定した天井までの距離情報に基づいて高低差を補正することが好ましい。 In the above-described embodiment, the piping parameter acquisition unit 13 acquires the piping parameters in conjunction with the image ranging unit 14, but in another embodiment, it is based on the input value manually input by the field worker. The piping parameters may be acquired. In this case, the local worker calculates, for example, the height difference of the indoor / outdoor unit based on the measured value of the altitude sensor mounted as standard on the mobile communication terminal 10, and inputs the value to the input form provided by the mobile communication terminal 10. Enter manually via. In the measurement method using the altitude sensor, an error occurs in the height difference by the distance from the position of the mobile communication terminal 10 to the ceiling where the indoor unit is installed. Therefore, regarding this, the AR major function of the mobile communication terminal 10 It is preferable to correct the height difference based on the distance information to the ceiling measured by using.

Ceiling cassette 2 directions, wall-mounted type, floor-standing type, etc.), etc.
　その後、携帯通信端末１０は、自動生成された設置環境情報に基づいて室内機３０の制御パラメータを導出する。ここでいう室内機３０の制御パラメータとは、例えば、風向ルーバーの枚数、吹き出し方向、風向ルーバーの制御段階数などであり、携帯通信端末１０は、室内機３０と窓との位置関係から最適な風向ルーバーの枚数や吹き出し方向を導出したり、天井の高さから最適な風向ルーバーの制御段階数を導出したりする。上述した手順で導出された制御パラメータは、携帯通信端末１０から室内機３０に送信され、室内機３０は、受信した制御パラメータを初期値として設定する。 After that, the mobile communication terminal 10 derives the control parameters of the indoor unit 30 based on the automatically generated installation environment information. The control parameters of the indoor unit 30 referred to here are, for example, the number of wind direction louvers, the blowing direction, the number of control steps of the wind direction louvers, and the like, and the mobile communication terminal 10 is optimal from the positional relationship between the indoor unit 30 and the window. The number of wind direction louvers and the blowing direction are derived, and the optimum number of wind direction louver control steps is derived from the height of the ceiling. The control parameters derived in the above procedure are transmitted from the mobile communication terminal 10 to the indoor unit 30, and the indoor unit 30 sets the received control parameters as initial values.
