Description

空気調和機および空気調和システムAir conditioner and air conditioning system
 本発明は、空気調和機および空気調和システムに関する。 The present invention relates to an air conditioner and an air conditioning system.
 近年、環境負荷を少なくするため、代替フロンガスを冷媒として用いた空気調和機が開発されている。このような冷媒として、例えば、ハイドロフルオロカーボン(HFC)類のR32などの微燃性冷媒が用いられる。 In recent years, in order to reduce the environmental load, an air conditioner using an alternative fluorocarbon gas as a refrigerant has been developed. As such a refrigerant, for example, a slightly flammable refrigerant such as hydrofluorocarbon (HFC) R32 or the like is used.
 空気調和機に微燃性冷媒を用いた場合、微燃性冷媒の漏洩に起因した発火の恐れがある。このため、この種の空気調和機では、漏洩検出センサを用いて微燃性冷媒の漏洩を高精度に検知する必要がある。しかしながら、漏洩検知センサは、経時劣化や故障により検出精度が低下するため、定期的な交換、修理などのメンテナンスが必要になるという問題がある。 When a slightly flammable refrigerant is used for the air conditioner, there is a risk of ignition due to the leakage of the slightly flammable refrigerant. For this reason, in this type of air conditioner, it is necessary to detect leakage of the slightly flammable refrigerant with high accuracy using a leakage detection sensor. However, since the leak detection sensor is deteriorated in detection accuracy due to deterioration with time or failure, there is a problem that maintenance such as regular replacement and repair becomes necessary.
 特許文献1には、複数の漏洩検知センサを設けた空気調和機が開示されている。 Patent Document 1 discloses an air conditioner provided with a plurality of leak detection sensors.
特開2014-224612号公報JP 2014-224612 A
 特許文献1に開示された空気調和機では、複数の漏洩検知センサを設けることで、何れかの漏洩検知センサが経時劣化や故障した場合でも、他の漏洩検知センサで微燃性冷媒の漏洩を検知できるため、漏洩検知センサの交換、修理などのメンテナンスの頻度を少なくすることができる。 In the air conditioner disclosed in Patent Document 1, by providing a plurality of leakage detection sensors, even if any of the leakage detection sensors deteriorate or fail over time, the leakage of the slightly flammable refrigerant is detected by another leakage detection sensor. Since the detection can be performed, the frequency of maintenance such as replacement or repair of the leak detection sensor can be reduced.
 しかしながら、特許文献1に開示された空気調和機では、複数の漏洩検知センサが同時に経時劣化や故障した場合、微燃性冷媒の漏洩を高精度に検出できない恐れがある。 However, in the air conditioner disclosed in Patent Document 1, when a plurality of leak detection sensors simultaneously deteriorate or fail over time, there is a possibility that the leak of the slightly flammable refrigerant can not be detected with high accuracy.

[Air conditioning system]
Hereinafter, an air conditioning system 1 according to an embodiment of the present invention will be described.
FIG. 1 is a block diagram for explaining the overall configuration of the air conditioning system 1 according to the embodiment.
FIG. 2 is a diagram for explaining an example of the output voltage Va of the refrigerant sensor 13.
 図1に示すように、空気調和システム1は、空気調和機10と、ネットワーク回線NTを介して空気調和機10に接続された外部サーバ300と、無線データ送受信装置200と、修理サービス担当者が保有する端末機器400とを有している。 As shown in FIG. 1, the air conditioning system 1 includes an air conditioner 10, an external server 300 connected to the air conditioner 10 via a network line NT, a wireless data transmission / reception device 200, and a person in charge of repair service. And the terminal device 400 to be held.
[空気調和機]
 図1に示すように、空気調和機10は、室内機11と、室外機12と、冷媒センサ13と、GPS(Global Positioning System:測位装置)14と、出力装置15とを有している。
[Air conditioner]
As shown in FIG. 1, the air conditioner 10 includes an indoor unit 11, an outdoor unit 12, a refrigerant sensor 13, a GPS (Global Positioning System: positioning device) 14, and an output device 15.
 空気調和機10では、室内に設置された室内機11と、室外に設置された室外機12との間で、冷媒R(代替フロンガス)が循環しており、この冷媒Rとの熱交換により室内機11から冷風又は温風が吹き出されるようになっている。実施の形態では、冷媒Rとして、代替フロンのハイドロフルオロカーボン(HFC)類のR32などの微燃性冷媒が用いられる。 In the air conditioner 10, the refrigerant R (substituting fluorocarbon gas) circulates between the indoor unit 11 installed indoors and the outdoor unit 12 installed outdoor, and heat exchange with the refrigerant R causes indoors. Cold air or warm air is blown from the machine 11. In the embodiment, as the refrigerant R, a slightly flammable refrigerant such as hydrofluorocarbon (HFC) R32 which is an alternative fluorocarbon is used.
 室内機11には、当該室内機11における冷媒Rの漏洩を検知するための冷媒センサ13が設けられている。冷媒センサ13は対応する室内機11に対して1つ設けられており、冷媒センサ13の製造番号と室内機11の製造番号とは一対一で関連付けられている。 The indoor unit 11 is provided with a refrigerant sensor 13 for detecting the leakage of the refrigerant R in the indoor unit 11. One refrigerant sensor 13 is provided for the corresponding indoor unit 11, and the manufacturing number of the refrigerant sensor 13 and the manufacturing number of the indoor unit 11 are associated one-on-one.
 冷媒センサ13は、空気中に漏洩した冷媒Rの粒子を検知するセンサ部(図示せず)を有しており、このセンサ部(図示せず)で検知した粒子の量により室内機11での冷媒Rの漏洩を検知する。 The refrigerant sensor 13 has a sensor unit (not shown) for detecting particles of the refrigerant R leaked into the air, and the amount of particles detected by the sensor unit (not shown) in the indoor unit 11 The leak of the refrigerant R is detected.
 図2に示すように、冷媒センサ13は、空気中に漏洩した冷媒Rの粒子の量に応じた電圧(出力電圧Va)を出力するようになっており、室内機11での冷媒Rの漏洩が多くなるほど出力電圧Vaが高くなる(図2の破線)。また、冷媒センサ13では、センサ部(図示せず)の経時劣化が進むに連れて出力電圧Vaが上昇する(図2の実線)。 As shown in FIG. 2, the refrigerant sensor 13 outputs a voltage (output voltage Va) according to the amount of particles of the refrigerant R leaked into the air, and the refrigerant R leaks in the indoor unit 11. The output voltage Va becomes higher as D.sub.i increases (the broken line in FIG. 2). Further, in the refrigerant sensor 13, as the deterioration with time of the sensor unit (not shown) progresses, the output voltage Va rises (solid line in FIG. 2).
 空気調和機10では、冷媒Rの漏洩又は経時劣化によるメンテナンス要否判断の閾値電圧Vthが設定されている。空気調和機10では、冷媒センサ13の出力電圧Vaが、この閾値電圧Vthを超えて高くなると、冷媒センサ13の交換、修理などのメンテナンスが必要と判断する。 In the air conditioner 10, a threshold voltage Vth for determining the necessity of maintenance due to leakage or deterioration with time of the refrigerant R is set. In the air conditioner 10, when the output voltage Va of the refrigerant sensor 13 becomes higher than the threshold voltage Vth, it is determined that maintenance such as replacement or repair of the refrigerant sensor 13 is necessary.
 空気調和機10では、冷媒センサ13の出力電圧Vaを、所定の間隔(例えば、4カ月)ごとに計測している。空気調和機10では、所定の間隔における第1計測タイミング(例えば、運転開始後54カ月)で計測した出力電圧Vaに基づいて、次回の第2計測タイミング(例えば、60カ月)で計測される予定の出力電圧Vaが、閾値電圧Vthを超えて高くなると判定した場合、冷媒センサ13の経時劣化によるメンテナンスが必要と判定する。 In the air conditioner 10, the output voltage Va of the refrigerant sensor 13 is measured at predetermined intervals (for example, four months). The air conditioner 10 is to be measured at the next second measurement timing (for example, 60 months) based on the output voltage Va measured at the first measurement timing (for example, 54 months after the start of operation) at a predetermined interval. When it is determined that the output voltage Va of the reference voltage becomes higher than the threshold voltage Vth, it is determined that maintenance due to deterioration with time of the refrigerant sensor 13 is necessary.
 つまり、空気調和機10は、冷媒センサ13の過去の出力電圧Vaの変化率に基づいて、将来の出力電圧Vaを予測し、次回の計測タイミング(第2計測タイミング)までに予測した出力電圧Vaが閾値電圧Vthを超えると判定した場合、冷媒センサ13のメンテナンスが必要と判定する。 That is, the air conditioner 10 predicts the future output voltage Va based on the change rate of the past output voltage Va of the refrigerant sensor 13, and predicts the output voltage Va by the next measurement timing (second measurement timing). When it is determined that the threshold voltage Vth exceeds the threshold voltage Vth, it is determined that the maintenance of the refrigerant sensor 13 is necessary.
 図1に戻って、冷媒センサ13には、当該冷媒センサ13の位置情報(設置場所を示す情報)を取得するGPS14が一体的に設けられている。このGPS14は、位置情報取得装置に相当する。 Returning to FIG. 1, the refrigerant sensor 13 is integrally provided with a GPS 14 for acquiring position information (information indicating an installation place) of the refrigerant sensor 13. The GPS 14 corresponds to a position information acquisition device.
 GPS14で取得された冷媒センサ13の位置情報は、冷媒センサ13の出力電圧Va及びその他の情報と共に、機器情報20として出力装置15に送信される。 The position information of the refrigerant sensor 13 acquired by the GPS 14 is transmitted to the output device 15 as the apparatus information 20 together with the output voltage Va of the refrigerant sensor 13 and other information.
 出力装置15は、インターネットなどのネットワーク回線NT又は、電話回線などの電気通信回線を通じて、外部サーバ300に接続されている。出力装置15は、冷媒センサ13の位置情報と出力電圧Vaを含む機器情報20を、ネットワーク回線NTを介して外部サーバ300に送信する。 The output device 15 is connected to the external server 300 through a network line NT such as the Internet or a telecommunication line such as a telephone line. The output device 15 transmits the device information 20 including the position information of the refrigerant sensor 13 and the output voltage Va to the external server 300 via the network line NT.
 また、出力装置15は、前述した各情報と合わせて、冷媒センサ13の製造番号、型式、冷媒種類に関する情報を機器情報20に含め、この機器情報20を、ネットワーク回線NTを介して外部サーバ300に送信する。 Further, the output device 15 includes the information related to the manufacturing number, model, and refrigerant type of the refrigerant sensor 13 in the device information 20 together with each information described above, and this device information 20 is transmitted to the external server 300 via the network line NT. Send to
 なお、出力装置15は、前述した冷媒センサ13の位置情報及び出力電圧Vaと合わせて、冷媒センサ13の設置時期情報、及び/又は冷媒センサ13の最初の通電時期に関する情報を取得できる場合、これらの情報を機器情報20に含め、ネットワーク回線NTを介して外部サーバ300に送信してもよい。 When the output device 15 can obtain the installation timing information of the refrigerant sensor 13 and / or the information regarding the first energization timing of the refrigerant sensor 13 in combination with the position information of the refrigerant sensor 13 and the output voltage Va described above, The above information may be included in the device information 20 and transmitted to the external server 300 via the network line NT.
 外部サーバ300では、RAM(Random Access Memory)などの記憶部310を有しており、この記憶部310に出力装置15から送信された機器情報20が一時的に記憶される。記憶部310に記憶された機器情報20の詳細は後述する。 The external server 300 includes a storage unit 310 such as a random access memory (RAM), and the storage unit 310 temporarily stores the device information 20 transmitted from the output device 15. The details of the device information 20 stored in the storage unit 310 will be described later.
 外部サーバ300は、記憶部310に記憶した機器情報20を、無線データ送受信装置200を介して、修理サービス担当者の保有する端末機器400に送信する。 The external server 300 transmits the device information 20 stored in the storage unit 310 to the terminal device 400 owned by the person in charge of repair service via the wireless data transmission / reception device 200.
 これにより、修理サービス担当者は、端末機器400に表示された機器情報20を参照して、メンテナンスが必要な冷媒センサ13の設置場所(位置情報)などを正確に把握することができ、冷媒センサ13のメンテナンスを効率よく行うことができる。 As a result, the repair service representative can accurately grasp the installation location (position information) of the refrigerant sensor 13 requiring maintenance with reference to the device information 20 displayed on the terminal device 400, and the refrigerant sensor Maintenance of 13 can be performed efficiently.

 次に、外部サーバ300の記憶部310に記憶された機器情報20の一例を説明する。
[Equipment information]
Next, an example of the device information 20 stored in the storage unit 310 of the external server 300 will be described.
 図3は、記憶部310に記憶された機器情報20の一例を説明する概念図である。 FIG. 3 is a conceptual diagram for explaining an example of the device information 20 stored in the storage unit 310. As shown in FIG.
 図3に示すように、機器情報20は、冷媒センサ13の位置情報21と、冷媒センサ13の型式情報22と、冷媒センサ13の製造番号情報23と、室内機11の運転開始の日時情報24と、室内機11の運転開始からの経過時間情報25と、冷媒Rの冷媒種類情報26と、冷媒センサ13の出力電圧Va情報と、を含んでいる。 As shown in FIG. 3, the device information 20 includes position information 21 of the refrigerant sensor 13, type information 22 of the refrigerant sensor 13, manufacturing number information 23 of the refrigerant sensor 13, and date and time information 24 of operation start of the indoor unit 11. , Elapsed time information 25 from the start of operation of the indoor unit 11, refrigerant type information 26 of the refrigerant R, and output voltage Va information of the refrigerant sensor 13.
 冷媒センサ13の位置情報21は、冷媒センサ13に一体的に設けられたGPS14により取得される。位置情報21は、冷媒センサ13(室内機11)の緯度、経度の平面座標と、冷媒センサ13(室内機11)の高さ位置の高低座標とを含んで構成される。 Position information 21 of the refrigerant sensor 13 is acquired by a GPS 14 provided integrally with the refrigerant sensor 13. The position information 21 includes plane coordinates of latitude and longitude of the refrigerant sensor 13 (indoor unit 11) and height coordinates of a height position of the refrigerant sensor 13 (indoor unit 11).
 実施の形態では、冷媒センサ13は、室内機11に対応して設けられているため、この冷媒センサ13の位置情報21に基づいて、室内機11の位置情報(設置場所)を取得できる。 In the embodiment, since the refrigerant sensor 13 is provided corresponding to the indoor unit 11, the position information (installation location) of the indoor unit 11 can be acquired based on the position information 21 of the refrigerant sensor 13.
 冷媒センサ13の型式情報22は、冷媒センサ13に固有に付された情報であり、この型式情報22に基づいて冷媒センサ13を特定できる。例えば、複数の冷媒センサ13を有する空気調和機10である場合、冷媒センサ13の型式情報22を参照することで、複数の冷媒センサ13の中から特定の冷媒センサ13を特定できる。 The type information 22 of the refrigerant sensor 13 is information uniquely assigned to the refrigerant sensor 13, and the refrigerant sensor 13 can be identified based on the type information 22. For example, in the case of the air conditioner 10 having a plurality of refrigerant sensors 13, a specific refrigerant sensor 13 can be specified from among the plurality of refrigerant sensors 13 by referring to the type information 22 of the refrigerant sensor 13.
 実施の形態では、冷媒センサ13は、室内機11に対応して設けられているため、冷媒センサ13の型式情報22に基づいて、室内機11を特定できる。 In the embodiment, since the refrigerant sensor 13 is provided corresponding to the indoor unit 11, the indoor unit 11 can be identified based on the type information 22 of the refrigerant sensor 13.
 冷媒センサ13の製造番号情報23は、冷媒センサ13に固有に付された識別情報であり、この製造番号情報23に基づいて冷媒センサ13を特定できる。なお、冷媒センサ13は、室内機11内に設けられているため、冷媒センサ13の製造番号情報23に基づいて、室内機11を特定できる。 The serial number information 23 of the refrigerant sensor 13 is identification information uniquely assigned to the refrigerant sensor 13, and the refrigerant sensor 13 can be identified based on the serial number information 23. Since the refrigerant sensor 13 is provided in the indoor unit 11, the indoor unit 11 can be identified based on the manufacturing number information 23 of the refrigerant sensor 13.
 室内機11の運転開始の日時情報24は、室内機11が最初に電源に接続され、室内機11に最初に通電された日時である。 The date and time information 24 of the operation start of the indoor unit 11 is the date and time when the indoor unit 11 is first connected to the power supply and the indoor unit 11 is first energized.
 冷媒センサ13は、センサ部(図示せず)が周囲雰囲気に晒された日時から劣化が始まる。そのため、空気調和機10では、室内機11の最初の運転開始の日時情報24を記憶しておき、この運転開始の日時情報24に冷媒センサ13が周囲雰囲気に晒された日時と仮定し、この日時情報24から劣化開始をカウントする。 The refrigerant sensor 13 starts to deteriorate from the date and time when the sensor unit (not shown) is exposed to the ambient atmosphere. Therefore, in the air conditioner 10, the date and time information 24 of the first operation start of the indoor unit 11 is stored, and the date and time information 24 of the operation start assumes that the refrigerant sensor 13 is exposed to the ambient atmosphere. The start of deterioration is counted from the date and time information 24.
 これにより、空気調和機10では、冷媒センサ13の経時劣化による出力電圧Vaの状態を取得することができる。なお、冷媒センサ13のセンサ部(図示せず)が周囲雰囲気に晒された日時情報を取得できる場合には、空気調和機10では、その日時から冷媒センサ13の劣化開始をカウントすることで、冷媒センサ13の経時劣化による出力電圧Vaの状態をより正確に取得することができる。 Thereby, in the air conditioner 10, the state of the output voltage Va due to the deterioration with time of the refrigerant sensor 13 can be acquired. When the sensor unit (not shown) of the refrigerant sensor 13 can obtain date and time information exposed to the surrounding atmosphere, the air conditioner 10 counts the start of deterioration of the refrigerant sensor 13 from that date and time, The state of the output voltage Va due to the deterioration with time of the refrigerant sensor 13 can be acquired more accurately.
 前述した室内機11の運転開始の日時情報24は、冷媒センサ13の設置時期情報、又は通電時期情報に相当する。 The date and time information 24 of the operation start of the indoor unit 11 described above corresponds to installation time information of the refrigerant sensor 13 or energization time information.
 室内機11の運転開始からの経過時間情報25は、室内機11に最初に通電された日時からの経過時間である。空気調和機10では、室内機11に通電された日時からの経過時間を取得することで、冷媒センサ13の経時劣化による出力電圧Vaの状態を正確に取得することができる。前述したように、冷媒センサ13のセンサ部(図示せず)が周囲雰囲気に晒された日時情報を取得できる場合には、その日時からの経過時間をカウントすることで、冷媒センサ13の経時劣化による出力電圧Vaの状態をより正確に取得できる。 The elapsed time information 25 from the start of operation of the indoor unit 11 is an elapsed time from the date and time when the indoor unit 11 is first energized. In the air conditioner 10, by acquiring the elapsed time from the date and time when the indoor unit 11 is energized, it is possible to accurately acquire the state of the output voltage Va due to the deterioration with time of the refrigerant sensor 13. As described above, when the sensor unit (not shown) of the refrigerant sensor 13 can acquire date and time information exposed to the surrounding atmosphere, the refrigerant sensor 13 is deteriorated with time by counting the elapsed time from that date and time. The state of the output voltage Va due to can be acquired more accurately.
 冷媒種類情報26は、空気調和機10で用いられる冷媒Rの種類が記憶されている。実施の形態では、冷媒Rとして、代替フロンのハイドロフルオロカーボン(HFC)類のR32などの微燃性冷媒が用いられる。この場合、冷媒種類情報26には、R32が記憶される。 The refrigerant type information 26 stores the type of the refrigerant R used in the air conditioner 10. In the embodiment, as the refrigerant R, a slightly flammable refrigerant such as hydrofluorocarbon (HFC) R32 which is an alternative fluorocarbon is used. In this case, R32 is stored in the refrigerant type information 26.
 冷媒センサ13の出力電圧27は、冷媒センサ13から出力された電圧値(出力電圧Va)である。出力電圧27は、電圧計(図示せず)で計測される。 The output voltage 27 of the refrigerant sensor 13 is a voltage value (output voltage Va) output from the refrigerant sensor 13. The output voltage 27 is measured by a voltmeter (not shown).
 前述した通り、空気調和機10では、冷媒センサ13に一体的に設けられたGPS14により冷媒センサ13の位置情報21を取得すると共に、この冷媒センサ13の位置情報21と、冷媒センサ13の出力電圧27情報とを含む機器情報20を取得し、ネットワーク回線NTを介して外部サーバ300に送信する。そして、空気調和システム1では、外部サーバ300に記憶された機器情報20を、修理サービス担当者の保有する端末機器400に送信する。よって、修理サービス担当者は、端末機器400に表示された機器情報20を確認することで、冷媒センサ13のメンテナンスの要否判定を行うと共に、メンテナンスが必要な冷媒センサ13の位置を正確に把握することができる。 As described above, in the air conditioner 10, the position information 21 of the refrigerant sensor 13 is acquired by the GPS 14 integrally provided to the refrigerant sensor 13, and the position information 21 of the refrigerant sensor 13 and the output voltage of the refrigerant sensor 13 The device information 20 including the T.27 information is acquired, and transmitted to the external server 300 via the network line NT. Then, the air conditioning system 1 transmits the device information 20 stored in the external server 300 to the terminal device 400 owned by the person in charge of repair service. Therefore, the repair service person in charge determines the necessity of maintenance of the refrigerant sensor 13 by confirming the device information 20 displayed on the terminal device 400, and accurately grasps the position of the refrigerant sensor 13 requiring maintenance. can do.
 なお、前述した実施の形態では、GPS14は、冷媒センサ13に一体的に設けられている場合を例示して説明したが、これに限定されるものではない、例えば、GPS14は、冷媒センサ13と分離して、室内機11に設けられていてもよく、また、室外機12に設けられていてもよい(図1の一点鎖線)。 In the embodiment described above, although the case where the GPS 14 is provided integrally with the refrigerant sensor 13 has been described as an example, the present invention is not limited to this. For example, the GPS 14 may be a refrigerant sensor 13 and It may be separated, and may be provided in the indoor unit 11, and may be provided in the outdoor unit 12 (one-dot chain line in FIG. 1).
 また、前述した実施の形態では、位置情報取得装置としてGPS14を用いた場合を例示して説明したが、冷媒センサ13などの位置情報を取得できる装置、方法であればこれに限定されるものではなく、無線通信装置、有線通信装置を用いた様々な位置情報取得装置、取得方法であってもよい。 Moreover, although the case where GPS14 was used as a positional information acquisition apparatus was illustrated and demonstrated in embodiment mentioned above, if it is an apparatus and method which can acquire positional information, such as refrigerant sensor 13, it will be limited to this Instead, a wireless communication device, various position information acquisition devices using a wired communication device, and an acquisition method may be used.
 なお、前述した機器情報20において、運転開始の日時情報24や運転開始からの経過時間25は、厳密に時分秒まで記録してもよく、月日の単位で記録してもよい。 In the device information 20 described above, the date and time information 24 of the operation start and the elapsed time 25 from the operation start may be strictly recorded up to hours, minutes and seconds, or may be recorded in units of days and days.
 以上説明した通り、実施の形態では、
(1)室内機11と室外機12との間で熱交換用の冷媒Rを循環させる空気調和機10において、冷媒Rの漏洩を検知する冷媒センサ13(漏洩検知センサ)と、冷媒センサ13の位置情報21を取得するGPS14(位置情報取得装置)と、GPS14で取得した位置情報21を空気調和機10の外部に出力する出力装置15と、を有する構成とした。
As described above, in the embodiment,
(1) In the air conditioner 10 in which the refrigerant R for heat exchange is circulated between the indoor unit 11 and the outdoor unit 12, the refrigerant sensor 13 (leakage detection sensor) detecting leakage of the refrigerant R, and the refrigerant sensor 13 The configuration includes the GPS 14 (position information acquisition device) that acquires the position information 21 and the output device 15 that outputs the position information 21 acquired by the GPS 14 to the outside of the air conditioner 10.
 このように構成すると、空気調和機10では、冷媒センサ13の正確な位置情報21がGPS14により取得されるので、外部の修理サービス担当者は、冷媒センサ13の設置場所を迅速、かつ正確に知ることができ、冷媒センサ13の交換、修理などのメンテナンス性を高めることができる。 According to this configuration, in the air conditioner 10, since the accurate position information 21 of the refrigerant sensor 13 is acquired by the GPS 14, the person in charge of the external repair service knows the installation place of the refrigerant sensor 13 quickly and accurately. It is possible to improve the maintainability of the refrigerant sensor 13 such as replacement and repair.
(2)また、機器情報取得装置は、GPS14(測位装置)であり、GPS14は、冷媒センサ13に一体的に設けられた構成とした。 (2) Further, the device information acquisition device is the GPS 14 (positioning device), and the GPS 14 is integrally provided to the refrigerant sensor 13.

Further, since the GPS 14 is provided integrally with the refrigerant sensor 13, the position information 21 of the refrigerant sensor 13 can be acquired with high accuracy.
(3)また、GPS14は、空気調和機10の室内機11に設けられている構成とした。 (3) Further, the GPS 14 is provided in the indoor unit 11 of the air conditioner 10.
 このように構成すると、空気調和機10では、室内機11の位置情報をGPS14により取得することができる。よって、修理サービス担当者は、GPS14で取得された室内機11の位置情報に基づいて、冷媒Rの漏洩のあった室内機11(冷媒センサ13)のメンテナンスを容易に行うことができる。 If comprised in this way, in the air conditioner 10, the positional information on the indoor unit 11 can be acquired by GPS14. Therefore, the person in charge of repair service can easily perform maintenance of the indoor unit 11 (the refrigerant sensor 13) in which the refrigerant R has leaked, based on the position information of the indoor unit 11 acquired by the GPS 14.
 また、GPS14は、冷媒センサ13とは個別に室内機11に設けられるので、冷媒Rの漏洩を検知する冷媒センサ13は、汎用性のあるセンサを用いることができる。 Further, since the GPS 14 is provided in the indoor unit 11 separately from the refrigerant sensor 13, the refrigerant sensor 13 for detecting the leakage of the refrigerant R can use a versatile sensor.
(4)また、GPS14は、空気調和機10の室外機12に設けられる構成とした。 (4) Further, the GPS 14 is provided to the outdoor unit 12 of the air conditioner 10.
 このように構成すると、一台の室外機12に対して複数の室内機11を有する空気調和機10である場合、室内機11ごとにGPS14を設ける必要がないため、空気調和機10の製造コストを抑えることができる。 With this configuration, in the case of the air conditioner 10 having a plurality of indoor units 11 for one outdoor unit 12, there is no need to provide the GPS 14 for each indoor unit 11, so the manufacturing cost of the air conditioner 10 is Can be reduced.
