Description

本発明は、一つの室内の天井側に複数台の室内機を備える空気調和機に関し、さらに詳しく言えば、人の在・不在に応じて上記各室内機の温度調節運転を制御する技術に関するものである。   The present invention relates to an air conditioner provided with a plurality of indoor units on the ceiling side of one room, and more specifically to a technique for controlling the temperature adjustment operation of each indoor unit according to the presence / absence of a person. It is.

大面積のオフィス等の室内を空調するにあたっては、通常、複数台の室内機が天井に設置されるが、例えば在室人数が少ない場合や、会議等で人が一箇所に集まっている場合でも、全室内機を運転することは省エネルギー等の観点からして好ましくない。   When air-conditioning indoors such as large-area offices, multiple indoor units are usually installed on the ceiling.For example, even when there are few people in the room or people gather in one place at a meeting etc. It is not preferable to operate all indoor units from the viewpoint of energy saving.

そこで、例えば特許文献１に記載されているように、室内を仮想的に複数のエリアに区画し、その各エリアごとに人検知センサと室内機とを設置し、人の在・不在に応じて各エリアの室内機の運転を制御するようにしている。   Therefore, for example, as described in Patent Document 1, a room is virtually divided into a plurality of areas, and a human detection sensor and an indoor unit are installed in each area, depending on the presence / absence of a person. The operation of indoor units in each area is controlled.

その一例として、図９に、オフィスフロア等の大部屋の室内１を第１ないし第９の９つのエリア１０ａ〜１０ｉに仮想的に区画した例を示す。図示が省略されているが、各エリア１０ａ〜１０ｉには、人検知センサと室内機とが設置されている。   As an example, FIG. 9 shows an example in which a room 1 of a large room such as an office floor is virtually divided into nine first to ninth areas 10a to 10i. Although illustration is omitted, a human detection sensor and an indoor unit are installed in each of the areas 10a to 10i.

例えば、第３エリア１０ｃと第７エリア１０ｇに人Ｈが居る場合には、第３エリア１０ｃと第７エリア１０ｇの室内機が運転され、他のエリア（１０ａ，１０ｂ，１０ｄ，１０ｅ，１０ｆ，１０ｈ，１０ｉ）の室内機は運転停止となる。   For example, when there is a person H in the third area 10c and the seventh area 10g, the indoor units in the third area 10c and the seventh area 10g are operated, and other areas (10a, 10b, 10d, 10e, 10f, The indoor unit 10h, 10i) is stopped.

このように、エリアごとに人検知センサと室内機を設けることにより、大部屋の室内１を、エリア単位で部分的に空調（調温）することができる。   Thus, by providing the human detection sensor and the indoor unit for each area, the room 1 in the large room can be partially air-conditioned (temperature-controlled) in units of areas.

特開平１１−３１１４３７号公報JP 11-311437 A

しかしながら、上記のように一つの室内に複数台の室内機を設置する場合、通常では、全室内機を運転した状態で快適な室内環境が得られるような空調システムが構築されているため、人検知センサで人が検知されたエリアの室内機のみを運転した場合、能力不足で快適性が得られない、という問題がある。   However, when installing a plurality of indoor units in one room as described above, since an air conditioning system that normally provides a comfortable indoor environment in a state where all the indoor units are operated is constructed. When only the indoor unit in the area where the person is detected by the detection sensor is operated, there is a problem that comfort is not obtained due to insufficient ability.

そこで、本発明の課題は、一つの室内を仮想的に複数のエリアに区画し、そのエリアごとに室内機とともに人の在・不在を検知する人検知センサを設置し、人が居る在エリアの室内機を運転するにあたって、その在エリアの快適性を確保することにある。   Therefore, the problem of the present invention is to virtually divide one room into a plurality of areas and install a human detection sensor for detecting the presence / absence of a person together with the indoor unit for each area. It is to ensure the comfort of the area where the indoor unit is operated.

上記課題を解決するため、請求項１に記載の発明は、一つの室内が仮想的に複数のエリアに区画され、上記各エリアの天井側にそれぞれ人検知センサと室内機とが設置され、上記人検知センサから出力される人の在・不在信号に応じて上記各室内機の運転が制御される空気調和機において、
上記各エリアの上記人検知センサから出力される上記在・不在信号を受信する制御部を有し、上記制御部は、上記人検知センサより在信号が出力されたエリアを在エリアとして、上記在エリアの上記室内機に運転指令を出すとともに、上記在エリアと隣り合う隣接エリアの上記室内機に運転指令を出すことを特徴としている。 In order to solve the above-mentioned problem, in the invention according to claim 1, one room is virtually divided into a plurality of areas, and a human detection sensor and an indoor unit are respectively installed on the ceiling side of each area. In the air conditioner in which the operation of each indoor unit is controlled according to the presence / absence signal of the person output from the human detection sensor,
A control unit that receives the presence / absence signal output from the human detection sensor in each area, and the control unit sets the area where the presence signal is output from the human detection sensor as the current area. An operation command is issued to the indoor unit in the area, and an operation command is issued to the indoor unit in the adjacent area adjacent to the existing area.

請求項２に記載の発明は、上記請求項１において、上記制御部は、隣接する２つのエリアの上記人検知センサから上記在信号を受信した場合、その２つのエリアに隣接する隣接エリアの上記室内機にも運転指令を出すことを特徴としている。   According to a second aspect of the present invention, in the first aspect, when the control unit receives the presence signal from the human detection sensor in two adjacent areas, the control unit in the adjacent area adjacent to the two areas. It is characterized by issuing operation commands to indoor units.

また、請求項３に記載の発明は、上記請求項１において、上記各エリアの区画された形状が長方形である場合、上記制御部は、上記隣接エリアの上記室内機に運転指令を出すにあたって、長辺側の隣接エリアの上記室内機に運転指令を出すことを特徴としている。   Further, in the invention according to claim 3, in the above claim 1, when the partitioned shape of each area is a rectangle, the control unit issues an operation command to the indoor unit in the adjacent area. An operation command is issued to the indoor unit in the adjacent area on the long side.

本発明によれば、一つの室内を仮想的に複数のエリアに区画し、そのエリアごとに室内機とともに人の在・不在を検知する人検知センサを設置し、人が居る在エリアの室内機を運転するにあたって、その在エリアと隣り合う隣接エリアの室内機を運転するようにしたことにより、在エリアの空調能力が高められ快適性が確保される。   According to the present invention, a room is virtually divided into a plurality of areas, and a person detection sensor for detecting the presence / absence of a person is installed together with the indoor unit for each area, and the indoor unit in the area where the person is present. When driving an indoor unit in an adjacent area adjacent to the existing area, the air conditioning capability of the existing area is increased, and comfort is ensured.

次に、図１ないし図７により、本発明の実施形態について説明するが、本発明はこれに限定されるものでない。   Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 7, but the present invention is not limited to this.

図１を参照して、この実施形態において、室内１は空調するうえで複数台の室内機を必要とするオフィスフロアであり、室内機を設置するにあたって、室内１が仮想的に複数のエリア１０に区画される。   Referring to FIG. 1, in this embodiment, room 1 is an office floor that requires a plurality of indoor units for air conditioning. When installing indoor units, room 1 is virtually divided into a plurality of areas 10. It is divided into.

この例において、室内１は、第１ないし第９までの９つのエリア１０ａ〜１０ｉに区画されている。なお、各エリア１０ａ〜１０ｉを区別する必要がない場合には総称としてエリア１０と言う。   In this example, the room 1 is divided into nine areas 10a to 10i from first to ninth. In addition, when it is not necessary to distinguish each area 10a-10i, the area 10 is called generically.

この実施形態に係る空気調和機は、エリア１０ａ〜１０ｉごとに設置される９台の室内機２０ａ〜２０ｉを備えている。室内機２０ａ〜２０ｉを区別する必要がない場合には総称として室内機２０と言う。   The air conditioner according to this embodiment includes nine indoor units 20a to 20i installed in the areas 10a to 10i. When it is not necessary to distinguish the indoor units 20a to 20i, the indoor units 20a and 20i are collectively referred to as the indoor unit 20.

各室内機２０は、好ましくは天井埋込型もしくはダクト型で、エリア１０の天井に設置される。図示しないが、各室内機２０は、基本的な構成として、送風ファンや熱交換器、吸気温度センサ等のほかに、後述する制御部４０との通信機能を有する室内機制御部を備えている。また、各室内機２０は、冷媒配管および制御線を介して室外機と接続されるが、室外機についてはその図示が省略されている。   Each indoor unit 20 is preferably a ceiling-embedded type or a duct type, and is installed on the ceiling of the area 10. Although not shown, each indoor unit 20 includes, as a basic configuration, an indoor unit control unit having a communication function with the control unit 40 described later, in addition to a blower fan, a heat exchanger, an intake air temperature sensor, and the like. . Moreover, although each indoor unit 20 is connected with an outdoor unit via refrigerant | coolant piping and a control line, the illustration is abbreviate | omitted about the outdoor unit.

また、エリア１０ａ〜１０ｉごとに、人の在・不在を検知して、人が存在する場合は「在」を、人が存在しない場合は「不在」を信号として出力する人検知センサ３０ａ〜３０ｉが設置される。なお、「在」信号と「不在」信号とを総称して「在・不在信号」と言う。また、人検知センサ３０ａ〜３０ｉを区別する必要がない場合には総称として人検知センサ３０と言う。人検知センサ３０は室内機２０と一体でもよい。   Further, in each of the areas 10a to 10i, the presence / absence of a person is detected, and when there is a person, “present” is output as a signal, and when there is no person, the person detection sensors 30a to 30i output “not present” as a signal. Is installed. The “present” signal and the “absent” signal are collectively referred to as “present / absent signal”. Moreover, when it is not necessary to distinguish the human detection sensors 30a to 30i, the human detection sensors 30 are collectively called. The human detection sensor 30 may be integrated with the indoor unit 20.

人検知センサ３０は、図２に示すように、一つのエリア１０を例えば９つのブロックＡ〜Ｉに細分化し、そのどのブロックに人が居るかを認識し得る画像処理機能を有する監視カメラであることが好ましいが、焦電型センサや反射型センサ、超音波センサ等であってもよい。   As shown in FIG. 2, the human detection sensor 30 is a surveillance camera having an image processing function that can subdivide one area 10 into, for example, nine blocks A to I and recognize which block a person is in. However, a pyroelectric sensor, a reflective sensor, an ultrasonic sensor, or the like may be used.

この空気調和機は、各室内機２０を統括する制御部４０を備えている。制御部４０は、各室内機２０と双方向通信が可能であり、少なくとも各室内機２０を介して人検知センサ３０が出力する在・不在信号を受信し、所定の室内機２０に対して運転指令を出す。なお、各室内機制御部は固有のアドレスを有し、制御部４０との通信には、その固有のアドレスが用いられる。制御部４０は、中央制御装置や集中リモコンであってもよい。   The air conditioner includes a control unit 40 that controls each indoor unit 20. The control unit 40 is capable of two-way communication with each indoor unit 20, receives at least the presence / absence signal output from the human detection sensor 30 via each indoor unit 20, and operates the predetermined indoor unit 20. Issue a command. Each indoor unit controller has a unique address, and the unique address is used for communication with the controller 40. The control unit 40 may be a central control device or a central remote controller.

本発明によると、人検知センサ３０から在信号が出力されたエリア２０を在エリアＸとして、その在エリアＸの室内機２０に温度調節のための運転指令が出されるとともに、在エリアＸと隣り合う隣接エリア２０が人が存在しないエリア（以下、隣接不在エリアＹと言う。）であっても、その隣接不在エリアＹの室内機２０にも運転指令が出される。なお、以下に説明する第１例ないし第６例を示す図３ないし図８において、在エリアＸには網掛けを付しており、隣接不在エリアＹには斜線（ハッチング）を付している。   According to the present invention, the area 20 where the presence signal is output from the human detection sensor 30 is defined as the existing area X, and an operation command for temperature adjustment is issued to the indoor unit 20 in the existing area X, and the adjacent area X is adjacent to the existing area X. Even if the matching adjacent area 20 is an area where there is no person (hereinafter referred to as an adjacent absence area Y), an operation command is also issued to the indoor unit 20 in the adjacent absence area Y. In FIGS. 3 to 8 showing the first to sixth examples described below, the existing area X is shaded and the adjacent absent area Y is hatched. .

各人検知センサ３０から制御部４０に対して、人の在・不在信号が送信されるが、第１例（図３参照）として、第７エリア１０ｇにのみ人Ｈが存在し、各人検知センサ３０から送信される信号のうち、第７エリア１０ｇの人検知センサ３０ｇからの信号が「在」で、これ以外の人検知センサ３０からの信号が「不在」であるとすると、制御部４０は、第７エリア１０ｇを在エリアＸとして、その室内機２０ｇに運転指令を出すとともに、第７エリア１０ｇに隣接する第４エリア１０ｄと第８エリア１０ｈをともに隣接不在エリアＹとしてその室内機２０ｄ，２０ｈにも運転指令を出す。   A person presence / absence signal is transmitted from each person detection sensor 30 to the control unit 40. As a first example (see FIG. 3), a person H exists only in the seventh area 10g, and each person detection is detected. Of the signals transmitted from the sensor 30, if the signal from the human detection sensor 30g in the seventh area 10g is “present” and the signals from the other human detection sensors 30 are “absent”, the control unit 40 Issues the operation command to the indoor unit 20g with the seventh area 10g as the existing area X, and the indoor unit 20d with the fourth area 10d and the eighth area 10h adjacent to the seventh area 10g as the adjacent absent area Y. , 20h.

これにより、第７エリア１０ｇの室内機２０ｇの空調能力に隣接する第４エリア１０ｄの室内機２０ｄと第８エリア１０ｈの室内機２０ｈの空調能力が加えられるため、第７エリア１０ｇの快適性が確保される。   As a result, the air conditioning capability of the indoor unit 20d in the fourth area 10d and the indoor unit 20h in the eighth area 10h adjacent to the air conditioning capability of the indoor unit 20g in the seventh area 10g is added, so the comfort of the seventh area 10g is improved. Secured.

次に、図４の第２例について説明する。この第２例は、上記第１例の第７エリア１０ｇに人Ｈが存在する状態に加えて、第３エリア１０ｃにも人Ｈが存在し、その人検知センサ３０ｃからの信号が「在」となった場合で、制御部４０は、上記第１例の運転状態に加えて、第３エリア１０ｃを在エリアＸとして、その室内機２０ｃに運転指令を出すとともに、第３エリア１０ｃに隣接する第２エリア１０ｂと第６エリア１０ｆをともに隣接不在エリアＹとしてその室内機２０ｂ，２０ｆにも運転指令を出す。   Next, a second example of FIG. 4 will be described. In the second example, in addition to the state in which the person H exists in the seventh area 10g of the first example, the person H also exists in the third area 10c, and the signal from the person detection sensor 30c is “present”. In this case, in addition to the operation state of the first example, the control unit 40 sets the third area 10c as the existing area X, issues an operation command to the indoor unit 20c, and is adjacent to the third area 10c. Both the second area 10b and the sixth area 10f are set as the adjacent absence area Y, and an operation command is also issued to the indoor units 20b and 20f.

次に、図５の第３例のように、第４エリア１０ｄにのみ人Ｈが存在している場合には、制御部４０は、第４エリア１０ｄを在エリアＸとして、その室内機２０ｄに運転指令を出すとともに、第４エリア１０ｄに隣接する第１エリア１０ａ，第５エリア１０ｅおよび第７エリア１０ｇのそれぞれを隣接不在エリアＹとしてその室内機２０ａ，２０ｅ，２０ｇにも運転指令を出す。   Next, as in the third example of FIG. 5, when the person H exists only in the fourth area 10 d, the control unit 40 sets the fourth area 10 d as the existing area X to the indoor unit 20 d. The operation command is issued, and the first area 10a, the fifth area 10e, and the seventh area 10g adjacent to the fourth area 10d are set as the adjacent absence area Y, and the operation command is also issued to the indoor units 20a, 20e, and 20g.

また、図６の第４例のように、中央の第５エリア１０ｅにのみ人Ｈが存在している場合には、制御部４０は、第５エリア１０ｅを在エリアＸとして、その室内機２０ｅに運転指令を出すとともに、第５エリア１０ｄに隣接する第２エリア１０ｂ，第４エリア１０ｄ，第６エリア１０ｆおよび第８エリア１０ｈのそれぞれを隣接不在エリアＹとしてその室内機２０ｂ，２０ｄ，２０ｆ，２０ｈにも運転指令を出す。   When the person H exists only in the central fifth area 10e as in the fourth example of FIG. 6, the control unit 40 sets the fifth area 10e as the existing area X and the indoor unit 20e. To the indoor area 20b, 20d, 20f, the second area 10b, the fourth area 10d, the sixth area 10f, and the eighth area 10h adjacent to the fifth area 10d. An operation command is also issued for 20 hours.

次に、隣接する２つのエリア２０の人検知センサ３０、例えば第７エリア１０ｇの人検知センサ３０ｇと、第８エリア１０ｈの人検知センサ３０ｈとから同時に「在」信号が出力され、図２のブロックＡ〜Ｉのうち、人Ｈが居るブロックアドレスとして、第７エリア１０ｇ側の人検知センサ３０ｇの「在」信号にブロックＦのアドレスが含まれ、第８エリア１０ｈ側の人検知センサ３０ｈの「在」信号にブロックＤのアドレスが含まれている場合、制御部４０は、図７に示すように、人Ｈが第７エリア１０ｇと第８エリア１０ｈの境界部分（もしくはその近辺）に存在すると判断し、第７エリア１０ｇと第８エリア１０ｈをともに在エリアＸとして、その室内機２０ｇ，２０ｈに運転指令を出すとともに、第７エリア１０ｇに隣接する第４エリア１０ｄ，第８エリア１０ｈに隣接する第５エリア１０ｅのそれぞれを隣接不在エリアＹとしてその室内機２０ｄ，２０ｅにも運転指令を出す。   Next, a “present” signal is simultaneously output from the human detection sensors 30 in the two adjacent areas 20, for example, the human detection sensor 30g in the seventh area 10g and the human detection sensor 30h in the eighth area 10h, as shown in FIG. Among the blocks A to I, as the block address where the person H is present, the “present” signal of the human detection sensor 30g on the seventh area 10g side includes the address of the block F, and the human detection sensor 30h on the eighth area 10h side. When the “present” signal includes the address of block D, as shown in FIG. 7, the control unit 40 indicates that the person H is present at (or near) the boundary between the seventh area 10 g and the eighth area 10 h. Accordingly, the seventh area 10g and the eighth area 10h are both set as the existing area X, and an operation command is issued to the indoor units 20g and 20h, and the fourth area adjacent to the seventh area 10g. A 10d, the indoor unit 20d, respectively as an adjacent absence area Y of the fifth area 10e adjacent to the eighth area 10h, issues a driving command to 20e.

また、図２のブロックＡ〜Ｉの別の応用例として、例えば図３で先に説明した第７エリア１０ｇが在エリアＸ、これに隣接する第４エリア１０ｄと第８エリア１０ｈとが隣接不在エリアＹである第１例において、第７エリア１０ｇの人検知センサ３０ｇからの「在」信号に含まれているブロックアドレスが「Ｂ」である場合には、人Ｈが第７エリア１０ｇ内で第４エリア１０ｄ側に居ると判断されるから、第４エリア１０ｄの室内機２０ｄに運転指令を出すようにしてもよく、このような態様も本発明に含まれる。   Further, as another application example of the blocks A to I in FIG. 2, for example, the seventh area 10g described above with reference to FIG. 3 is the existing area X, and the fourth area 10d and the eighth area 10h adjacent thereto are not adjacent. In the first example of the area Y, when the block address included in the “present” signal from the human detection sensor 30g in the seventh area 10g is “B”, the person H is in the seventh area 10g. Since it is determined to be on the fourth area 10d side, an operation command may be issued to the indoor unit 20d in the fourth area 10d, and such an aspect is also included in the present invention.

また、別の例として、図８に示すように、各エリア１０が短辺をａ，長辺をｂとする長方形状に区画されている場合について説明する。通常、各エリア１０の中央に室内機２０が配置される。したがって、エリア１０が長方形である場合、長辺側に隣接する２つのエリア１０の室内機２０間の距離は、短辺側に隣接する２つのエリアの室内機２０間の距離よりも短いことになる。   As another example, as shown in FIG. 8, a case will be described in which each area 10 is partitioned into a rectangular shape having a short side a and a long side b. Usually, the indoor unit 20 is arranged in the center of each area 10. Therefore, when the area 10 is rectangular, the distance between the indoor units 20 in the two areas 10 adjacent on the long side is shorter than the distance between the indoor units 20 in the two areas adjacent on the short side. Become.

図８の例において、第７エリア１０ｇのみが在エリアＸであるため、第４エリア１０ｄと第８エリア１０ｈとが隣接不在エリアＹとなるが、短辺ａ側の第８エリア１０ｈの室内機２０ｈには運転指令を出さず、長辺ｂ側に隣接する第４エリア１０ｄの室内機２０ｄにのみ運転指令を出すようにすることもできる。   In the example of FIG. 8, since only the seventh area 10g is the existing area X, the fourth area 10d and the eighth area 10h become the adjacent absent area Y, but the indoor unit in the eighth area 10h on the short side a side. It is also possible to issue an operation command only to the indoor unit 20d in the fourth area 10d adjacent to the long side b side without issuing an operation command at 20h.

これによれば、第７エリア１０ｇから見て、第４エリア１０ｄの室内機２０ｄの方が第８エリア１０ｈの室内機２０ｈよりも近い距離にあるため、第７エリア１０ｇの空調能力をより効果的に高めることができる。   According to this, since the indoor unit 20d in the fourth area 10d is closer to the indoor unit 20h in the eighth area 10h when viewed from the seventh area 10g, the air conditioning capacity of the seventh area 10g is more effective. Can be enhanced.

上記した各例では、制御部４０から、在エリアＸの室内機２０にも運転指令を出すようにしているが、在エリアＸの室内機２０については、自機の室内機制御部によりその運転を制御し、制御部４０は、在エリアＸに隣接する不在エリアＹの室内機の運転のみを制御するようにしてもよい。   In each example described above, an operation command is issued from the control unit 40 to the indoor unit 20 in the existing area X. However, for the indoor unit 20 in the existing area X, the operation is performed by the own indoor unit control unit. The control unit 40 may control only the operation of the indoor unit in the absent area Y adjacent to the existing area X.
