Description

【０００１】
【発明の属する技術分野】
本発明は、空調機の運転制御方法及び装置、例えば、事務所等の室内の温度の制御に用いられ、特に、温度センサで検出した温度が所定の目標値になるように、空調機の運転制御を行う方法及び装置に関する。
【０００２】
【従来の技術】
従来の空調機の運転制御方法及び装置においては、室内のある位置に１つの温度センサを設置し、この温度センサで検出した温度が所定の目標値になるように、空調機の運転制御を行っている。この場合、温度センサは、特に温度を目標値に一致させたい空間、例えば事務所内の温度を制御する場合は、人が居る確率が高い執務位置に近い位置を選んで設置される。
【０００３】
【発明が解決しようとする課題】
しかしながら、この従来の空調機の運転制御方法及び装置においては、温度センサ設置後に、事務所内のレイアウト変更を行って、執務位置と温度センサの間に仕切りがされたり、温度センサの近くにコピー機等の発熱体が設置された場合には、温度センサ付近の温度と執務位置の温度が異なってしまい、執務位置の温度を目標値通りに制御できないという問題があった。さらに、季節及び時刻の違いによる事務所内への日照の変化や、外気温度の変化や、室内の空気の流れの変化等の影響によっても、温度センサ付近の温度と執務位置の温度が異なってしまう場合があり、これらの場合も執務位置の温度を目標値通りに制御できないという問題があった。これらの問題に対しては、空調機の設備管理者が目標温度を頻繁に変更することで対応していたので、空調機の設備管理者に過度の負担を強いるという課題があった。また、事務所内のレイアウト変更による要因については、温度センサの配線を変更して温度センサの設置位置を変更すれば対応できるが、事務所内のレイアウト変更を行うごとに温度センサの配線を変更しなければならないので、この場合も、空調機の設備管理者に過度の負担を強いるという課題があった。
【０００４】
本発明は上記課題に鑑みてなされたものであり、温度センサ設置後に事務所内のレイアウト変更が行われたり、季節及び時刻の違いによる事務所内への日照の変化や、外気温度の変化や、室内の空気の流れの変化等の影響があった場合においても、空調機の設備管理者に目標温度設定の頻繁な変更や温度センサの配線変更等の過度の負担を強いることなく、執務位置の温度制御の精度を向上させることができる空調機の運転制御方法及び装置を提供することを目的とする。

本発明に係る方法は、さらに、外気の温度を検出し、この外気温度検出値に基づいて各位置での重み付け室温を算出することを特徴とする。
【００１２】
このように、外気温度に基づいて各位置での重み付け室温を算出する。これによって、各位置での温度センサの制御に対する重み付けの度合いを、外気温度に応じて設定することができる。
【００１３】

【００２３】
【発明の実施の形態】
以下、本発明の好適な実施の形態について図面に基づき詳細に説明する。
【００２４】
図１は、本発明の実施の形態に係る空調機の運転制御方法が実施される装置の構成を示す図であり、事務所内の温度を制御する場合に本発明を適用したものである。冷房用の冷風または暖房用の熱風を吹き出す空調機２０が事務所１０外に設置されている。空調機２０からの風を事務所１０内に供給するための給気ダクト２８と事務所１０内の空気を空調機２０に戻すための還気ダクト３０が、事務所１０内外に設置されている。空調機２０内の温度調節弁の開度を制御するための温度調節器２２が、配線ケーブル２６によって接続されている。空調機制御手段としてのビル管理システム１６が、温度調節器２２と配線ケーブル２４によって接続されている。事務所１０内の温度を検出するための室内用温度センサ１２−１〜１２−４が、ビル管理システム１６と配線ケーブル１８によって接続されて事務所１０内の各位置に設置されている。外気の温度を検出するための外気用温度センサ１４が、配線ケーブル３４によって接続されて建物外に設置されている。
【００２５】
ビル管理システム１６は、室内用温度センサ１２−１〜１２−４及び外気用温度センサ１４の検出値を読み込み、後述する温度指令値算出ルーチンにより温度調節器２２への指令値を算出する。温度調節器２２はその指令値に基づいて空調機２０の冷暖房パワーを制御する。空調機２０からの冷風または熱風が給気ダクト２８を通じて事務所１０内に供給され、事務所１０内の空気が還気ダクト３０を通じて空調機２０に戻されることにより、事務所１０内の執務位置３２の温度が所定の目標値に制御される。
【００２６】
本発明において特徴的なことは、室内用温度センサ１２−１〜１２−４の各検出値に重み付けを行って、各位置での重み付け室温を算出し、この各位置での重み付け室温に基づいて温度調節器２２への指令値を算出して空調機２０の冷暖房パワーを制御することである。
【００２７】
図２は、ビル管理システム１６内で実行される温度調節器２２への指令値を算出するための温度指令値算出ルーチンを示すフローチャートであり、このルーチンは所定時間おきに繰り返される。温度指令値算出ルーチンにおいては、まずステップ（以下Ｓと記述する）１が実行され、室内用温度センサ１２−１〜１２−４の位置に対応した変数ｉの値が１（室内用温度センサ１２−１が対応する）に設定される。次にＳ２に移行し、外気用温度センサ１４の検出値と現在の月日及び曜日及び時刻が読み込まれ、Ｓ３に移行し、ｉ＝１に対応した室内用温度センサ１２−１の検出値が読み込まれる。
【００２８】
Ｓ４においては、月日による重み付け係数Ａ１が設定される。重み付け係数Ａ１の値としては、例えば０．０〜２．０の値が使用される（以下、すべての重み付け係数についても同様である）。重み付け係数Ａ１は、図３に示す月日と重み付け係数Ａ１との間の特性マップにより設定される。図３の特性マップは、ビル管理システム１６に予め記憶させておく。特性マップの設定方法は、執務位置３２の温度と室内用温度センサ１２−１の検出値との偏差が月日によって変化する度合いに応じて設定される。例えば、真夏の日照の影響により、執務位置３２の温度と室内用温度センサ１２−１の検出値との偏差が大きくなる場合には、室内用温度センサ１２−１の制御への寄与度を低くするために、真夏の月日での重み付け係数Ａ１の値を１．０未満に設定しておく。
【００２９】
Ｓ５においては、外気温度による重み付け係数Ｂ１が設定される。重み付け係数Ｂ１は、図４に示す外気温度と重み付け係数Ｂ１との間の特性マップにより設定される。図４の特性マップは、ビル管理システム１６に予め記憶させておく。特性マップの設定方法は、執務位置３２の温度と室内用温度センサ１２−１の検出値との差と、外気用温度センサ１４の検出値とが相関する度合いに応じて設定される。例えば、外気温が高く、外気温度の変化により執務位置３２の温度と室内用温度センサ１２−１の検出値との差も変化する場合には、室内用温度センサ１２−１の制御への寄与度を低くするために、外気温度が高い値での重み付け係数Ｂ１の値を１．０未満に設定しておく。
【００３０】
Ｓ６においては、曜日時刻による重み付け係数Ｃ１が設定される。重み付け係数Ｃ１は、図５に示す曜日時刻と重み付け係数Ｃ１との間の特性マップにより設定される。図５の特性マップは、ビル管理システム１６に予め記憶させておく。特性マップの設定方法は、執務位置３２の温度と室内用温度センサ１２−１の検出値との偏差が曜日時刻によって変化する度合いに応じて設定される。例えば、真昼の日照の影響により、執務位置３２の温度と室内用温度センサ１２−１の検出値との偏差が大きくなる場合には、室内用温度センサ１２−１の制御への寄与度を低くするために、真昼の時刻での重み付け係数Ｃ１の値を１．０未満に設定しておく。あるいは、事務所１０内の空気の流れが悪く建物が蓄熱している休日明けの朝に、執務位置３２の温度と室内用温度センサ１２−１の検出値との偏差が大きくなる場合には、休日明けの朝での重み付け係数Ｃ１の値を、冷房ならば１．０以上、暖房ならば１．０未満に設定しておく。
【００３１】
Ｓ７においては、室内用温度センサ１２−１周辺の環境による重み付け係数Ｄ１が設定される。重み付け係数Ｄ１の設定方法としては、例えば室内用温度センサ１２−１と執務位置３２とが仕切られ、執務位置３２の温度と室内用温度センサ１２−１の検出値との偏差が常に大きい場合には、室内用温度センサ１２−１の検出値を制御に反映させないために、重み付け係数Ｄ１の値を０．０または０．０に近い値に設定しておく。一方、室内用温度センサ１２−１の検出値を制御に反映させたい場合は、重み付け係数Ｄ１の値を１．０以上に設定しておく。
【００３２】
本発明においては、図６に示す目標室内温度と室内用温度センサ１２−１の検出値との偏差と、重み付け係数Ｄ１との間の特性マップにより設定してもよい。図６の特性マップは、ビル管理システム１６に予め記憶させておく。特性マップの設定方法は、例えば、目標室内温度と室内用温度センサ１２−１の検出値との偏差が大きくなる場合には、室内用温度センサ１２−１の制御への寄与度を低くするために、偏差値が大きい場合における重み付け係数Ｄ１の値を１．０未満に設定しておく。ただし、図６の特性マップにより重み付け係数Ｄ１を設定する場合、温度指令値算出ルーチンの１回目の実行時においては、まだ目標室内温度が決定されていないので、１回目だけはＤ１の値を１．０に設定しておく。図６の特性マップを用いれば、仕切りや発熱体の有無等の室内用温度センサ１２−１の周辺環境の影響だけでなく、日照の変化の影響も考慮して重み付け係数Ｄ１の値を設定できる。また、図６の特性マップにおいて、目標室内温度の代わりに各室内用温度センサ１２−１〜１２−４の検出値の平均値を用いて偏差を算出してもよい。
【００３３】
次にＳ８に移行し、Ｓ４〜Ｓ７で算出された各重み付け係数Ａ１、Ｂ１、Ｃ１、Ｄ１の平均値を算出し、総合重み付け係数Ｋ１を算出する。そしてＳ９に移行し、室内用温度センサ１２−１の検出値に総合重み付け係数Ｋ１を乗じて重み付け室温Ｍ１を算出する。次にＳ１０に移行し、変数ｉの値を１つ増し、Ｓ１１では、変数ｉの値が室内用温度センサ１２−１〜１２−４の数（本実施の形態では４）より大きいか否かを判定する。
【００３４】
Ｓ１１でＮＯの場合は、Ｓ３に戻り、他の室内用温度センサ１２−２についてＳ３からＳ１０を実行し、各重み付け係数Ａ２、Ｂ２、Ｃ２、Ｄ２、総合重み付け係数Ｋ２、重み付け室温Ｍ２を算出し、すべての室内用温度センサ１２−１〜１２−４についてＳ３からＳ１０を実行する。
【００３５】
すべての室内用温度センサ１２−１〜１２−４についてＳ３からＳ１０を実行し、Ｓ１１でＹＥＳの場合は、Ｓ１２に移行し、重み付け室温Ｍ１、Ｍ２、Ｍ３、Ｍ４の平均値を算出し、目標室内温度を算出する。これにより、各位置での室内用温度センサ１２−１〜１２−４の検出値に重み付けが考慮されて目標室内温度が算出される。ただし、重み付け室温Ｍ１、Ｍ２、Ｍ３、Ｍ４の平均値を目標室内温度として扱うために、すべての重み付け係数（本実施の形態では１６個）の平均値を１．０に設定している。次にＳ１３に移行し、温度調節器２２に目標室内温度指令値を出力し、本ルーチンの実行を終了する。
【００３６】
また、本ルーチンにおいては、重み付け係数Ａ１、Ａ２、Ａ３、Ａ４（Ｂ、Ｃ、Ｄについても同様）の平均値は１．０でなくてもよく、例えば、月日による重み付けの方法を制御に反映させたい場合は、月日による重み付け係数Ａ１、Ａ２、Ａ３、Ａ４の平均値が１．０以上になるように各重み付け係数Ａ１、Ａ２、Ａ３、Ａ４の値を設定すればよい。これにより、複数の重み付けの方法の影響度を考慮した上で最適な重み付け係数を設定することができる。
【００３７】
本発明においては、事務所内に複数の室内用温度センサを設置し、各位置での室内用温度センサの検出値に重み付けを行って、各位置での重み付け室温を算出し、この各位置での重み付け室温に基づいて目標室内温度を算出する。そして、室内用温度センサの重み付けの方法は、執務位置と室内用温度センサとの間の仕切りや、発熱体や、日照及び外気温度の変化等の影響により執務位置と室内用温度センサ付近の温度に偏差が発生する複数の要因を考慮し、かつ各要因ごとの重み付けも考慮した上で、重み付けがなされる。したがって、仕切りや発熱体や日照及び外気温度の変化等の影響を受けず、制御指令に反映させたい室内用温度センサについては、重み付けを高く設定し、仕切りや発熱体や日照及び外気温度の変化等の影響を受け、制御指令に反映させたくない室内用温度センサについては、重み付けを低く設定できるので、空調機の設備管理者に過度の負担を強いることなく、執務位置の温度制御の精度を向上させることができる。
【００３８】
なお、本実施の形態においては、事務所内の温度を制御するために本発明を適用した場合について説明したが、電算機室等の室内の温度の制御に適用しても同様の効果が得られる。さらに、本発明の実施の形態においては、４個の温度センサを用いて空調機の制御を行った場合について説明したが、実際には、温度センサの数は被空調空間の大きさや用途に合わせて変更される。また、各重み付け係数の設定範囲は０．０〜２．０に限定されるものではなく任意に設定してよい。

BACKGROUND OF THE INVENTION
The present invention is used for controlling an air conditioner operation control method, for example, an indoor temperature in an office or the like. In particular, the air conditioner operation is performed so that the temperature detected by the temperature sensor becomes a predetermined target value. The present invention relates to a method and an apparatus for performing control.
[0002]
[Prior art]
In the conventional air conditioner operation control method and apparatus, one temperature sensor is installed at a certain position in the room, and the air conditioner operation is controlled so that the temperature detected by this temperature sensor becomes a predetermined target value. ing. In this case, the temperature sensor is installed by selecting a position close to the office position where there is a high probability that there is a person, particularly when controlling the temperature in the space where the temperature is desired to match the target value, for example, the temperature in the office.
[0003]
[Problems to be solved by the invention]
However, in this conventional air conditioner operation control method and apparatus, after the temperature sensor is installed, the layout in the office is changed so that the office position and the temperature sensor are partitioned, or the copy machine is located near the temperature sensor. When a heating element such as the above is installed, the temperature in the vicinity of the temperature sensor and the temperature at the office position are different, and the temperature at the office position cannot be controlled according to the target value. In addition, the temperature near the temperature sensor and the temperature at the office location will also differ due to the effects of changes in sunshine inside the office due to differences in season and time, changes in the outside air temperature, changes in the flow of indoor air, etc. In these cases, there was a problem that the temperature at the office position could not be controlled as the target value. Since these problems were dealt with by the air conditioner equipment manager changing the target temperature frequently, there was a problem of imposing an excessive burden on the air conditioner equipment manager. In addition, the cause of the layout change in the office can be dealt with by changing the temperature sensor wiring and changing the temperature sensor installation position, but the temperature sensor wiring must be changed each time the office layout is changed. In this case as well, there is a problem that an excessive burden is imposed on the air conditioner equipment manager.
[0004]
The present invention has been made in view of the above problems, and the layout in the office is changed after the installation of the temperature sensor, the change in sunshine in the office due to the difference in season and time, the change in the outside air temperature, Even if there is an effect of changes in the air flow of the air conditioner, the temperature at the office position is not imposed on the air conditioner equipment administrator without undue burden, such as frequent changes in the target temperature setting and changes in the temperature sensor wiring. It is an object of the present invention to provide an operation control method and apparatus for an air conditioner that can improve control accuracy.
[0005]
[Means for Solving the Problems]
In order to achieve such an object, the method according to the reference example of the present invention detects the temperature at a plurality of positions in the room, weights each detected temperature in the room, and calculates the weighted room temperature at each position. The room temperature is controlled by an air conditioner based on the weighted room temperature at each position.
[0006]
Thus, the room temperature at each position is weighted, and the room temperature is controlled by the air conditioner based on the room temperature at each weighted position. Thereby, the degree of weighting for the control of the temperature sensor at each position can be set according to the environment around the temperature sensor. Therefore, for temperature sensors separated from the work position and temperature sensors near the heating element, the control weight is set low so that the temperature control accuracy of the work position can be reduced without imposing a burden on the air conditioner equipment administrator. Can be improved.
[0007]
The method according to the present invention further determines a target room temperature based on a weighted room temperature at each position, and calculates a weighted room temperature at each position based on a deviation between the target room temperature and the detected room temperature. It is characterized by that.
[0008]
In this way, the weighted room temperature at each position is calculated based on the deviation between the target room temperature and the room temperature detection value. Thus, the degree of weighting for the control of the temperature sensor at each position can be set according to the deviation between the target indoor temperature and the value of the temperature sensor. Therefore, for temperature sensors that have a large deviation from the target room temperature due to the influence of partitions, heating elements, changes in sunshine, etc., by setting a low weight for control, it does not impose a burden on the air conditioner equipment administrator. It is possible to improve the temperature control accuracy of the office position.
[0009]
The method according to the present invention is further characterized in that the current month and day are read, and the weighted room temperature at each position is calculated based on the current month and day.
[0010]
Thus, the weighted room temperature at each position is calculated based on the current date. Thereby, the degree of weighting for the control of the temperature sensor at each position can be set according to the change of the sunshine into the office due to the difference in season.
[0011]
The method according to the present invention is further characterized in that the temperature of the outside air is detected, and the weighted room temperature at each position is calculated based on the outside air temperature detection value.
[0012]
Thus, the weighted room temperature at each position is calculated based on the outside air temperature. Thereby, the degree of weighting for the control of the temperature sensor at each position can be set according to the outside air temperature.
[0013]
The method according to the present invention is further characterized in that the current day of the week and time are read and the weighted room temperature at each position is calculated based on the current day of the week and time.
[0014]
In this way, the weighted room temperature at each position is calculated based on the current day of the week and time. As a result, the degree of weighting for temperature sensor control at each position can be set according to changes in sunshine in the office due to differences in time, or according to changes in indoor air flow due to differences in days of the week and times. Can be set.
[0015]
The method according to the present invention is further characterized in that the weighted room temperature at each position is calculated by combining two or more of the weighted room temperature calculation methods.
[0016]
In this manner, the weighted room temperature at each position is calculated by combining two or more of the weighted room temperature calculation methods. As a result, the degree of weighting for the control of the temperature sensor at each position can be optimally set in consideration of the respective degrees of influence of a plurality of factors having different temperatures near the temperature sensor and the temperature at the office position. .
[0017]
Apparatus according to a reference example of the present invention performs a plurality of room temperature detecting means for detecting a temperature of each position in the room, the weights each room detection values detected by the room temperature detecting means, room temperature weighting at each position Weighted room temperature calculating means, and air conditioner control means for controlling the room temperature by an air conditioner based on the weighted room temperature at each position.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.
[0024]
FIG. 1 is a diagram showing a configuration of an apparatus in which an operation control method for an air conditioner according to an embodiment of the present invention is implemented, and the present invention is applied when controlling the temperature in an office. An air conditioner 20 that blows out cool air for cooling or hot air for heating is installed outside the office 10. An air supply duct 28 for supplying the air from the air conditioner 20 into the office 10 and a return air duct 30 for returning the air in the office 10 to the air conditioner 20 are installed inside and outside the office 10. . A temperature controller 22 for controlling the opening degree of the temperature control valve in the air conditioner 20 is connected by a wiring cable 26. A building management system 16 as an air conditioner control means is connected to the temperature controller 22 and a wiring cable 24. Indoor temperature sensors 12-1 to 12-4 for detecting the temperature in the office 10 are connected to the building management system 16 and the wiring cable 18 and are installed at respective positions in the office 10. An outside air temperature sensor 14 for detecting the temperature of the outside air is connected to the wiring cable 34 and installed outside the building.
[0025]
The building management system 16 reads the detected values of the indoor temperature sensors 12-1 to 12-4 and the outside air temperature sensor 14, and calculates a command value to the temperature controller 22 by a temperature command value calculation routine described later. The temperature controller 22 controls the air conditioning power of the air conditioner 20 based on the command value. The cold air or hot air from the air conditioner 20 is supplied into the office 10 through the air supply duct 28, and the air in the office 10 is returned to the air conditioner 20 through the return air duct 30. The temperature of 32 is controlled to a predetermined target value.
[0026]
What is characteristic in the present invention is that each detected value of the indoor temperature sensors 12-1 to 12-4 is weighted to calculate a weighted room temperature at each position, and based on the weighted room temperature at each position. A command value to the temperature controller 22 is calculated to control the air conditioning power of the air conditioner 20.

FIG. 2 is a flowchart showing a temperature command value calculation routine for calculating a command value to the temperature controller 22 executed in the building management system 16, and this routine is repeated every predetermined time. In the temperature command value calculation routine, step (hereinafter referred to as S) 1 is first executed, and the value of the variable i corresponding to the position of the indoor temperature sensors 12-1 to 12-4 is 1 (the indoor temperature sensor 12). -1 corresponds). Next, the process proceeds to S2, and the detected value of the outside air temperature sensor 14, the current date, day, and time are read. The process proceeds to S3, and the detected value of the indoor temperature sensor 12-1 corresponding to i = 1. Is read.
[0028]
In S4, a weighting coefficient A1 based on the date is set. As the value of the weighting coefficient A1, for example, a value of 0.0 to 2.0 is used (hereinafter, the same applies to all weighting coefficients). The weighting coefficient A1 is set by a characteristic map between the date and the weighting coefficient A1 shown in FIG. The characteristic map of FIG. 3 is stored in advance in the building management system 16. The characteristic map setting method is set according to the degree to which the deviation between the temperature at the office position 32 and the detected value of the indoor temperature sensor 12-1 varies depending on the date. For example, when the deviation between the temperature at the office position 32 and the detected value of the indoor temperature sensor 12-1 becomes large due to the influence of sunlight in midsummer, the contribution to the control of the indoor temperature sensor 12-1 is low. In order to do this, the value of the weighting coefficient A1 in the midsummer month is set to less than 1.0.
[0029]
In S5, a weighting coefficient B1 based on the outside air temperature is set. The weighting coefficient B1 is set by a characteristic map between the outside air temperature and the weighting coefficient B1 shown in FIG. The characteristic map of FIG. 4 is stored in advance in the building management system 16. The characteristic map is set according to the degree of correlation between the difference between the temperature at the office position 32 and the detected value of the indoor temperature sensor 12-1 and the detected value of the outdoor temperature sensor 14. For example, when the outside air temperature is high and the difference between the temperature at the office position 32 and the detected value of the room temperature sensor 12-1 also changes due to a change in the outside air temperature, it contributes to the control of the room temperature sensor 12-1. In order to lower the degree, the value of the weighting coefficient B1 at a high outside air temperature is set to less than 1.0.
[0030]
In S6, the weighting coefficient C1 according to the day of the week is set. The weighting coefficient C1 is set by a characteristic map between the day of the week time and the weighting coefficient C1 shown in FIG. The characteristic map of FIG. 5 is stored in advance in the building management system 16. The characteristic map setting method is set according to the degree to which the deviation between the temperature at the office position 32 and the detected value of the indoor temperature sensor 12-1 varies depending on the day of the week. For example, when the deviation between the temperature at the office position 32 and the detected value of the indoor temperature sensor 12-1 becomes large due to the effect of sunlight at midday, the degree of contribution to the control of the indoor temperature sensor 12-1 is low. In order to do this, the value of the weighting coefficient C1 at noon is set to less than 1.0. Or, when the deviation between the temperature at the office position 32 and the detected value of the indoor temperature sensor 12-1 becomes large on the morning of the holiday when the air flow in the office 10 is poor and the building is storing heat, The value of the weighting coefficient C1 in the morning after the holiday is set to 1.0 or more for cooling and less than 1.0 for heating.
[0031]
In S7, the weighting coefficient D1 according to the environment around the indoor temperature sensor 12-1 is set. As a setting method of the weighting coefficient D1, for example, when the indoor temperature sensor 12-1 and the office position 32 are partitioned, and the deviation between the temperature of the office position 32 and the detected value of the indoor temperature sensor 12-1 is always large. In order not to reflect the detection value of the indoor temperature sensor 12-1 in the control, the value of the weighting coefficient D1 is set to 0.0 or a value close to 0.0. On the other hand, when the detection value of the indoor temperature sensor 12-1 is to be reflected in the control, the value of the weighting coefficient D1 is set to 1.0 or more.
[0032]
In the present invention, a characteristic map between the deviation between the target room temperature and the detected value of the room temperature sensor 12-1 and the weighting coefficient D1 shown in FIG. 6 may be used. The characteristic map of FIG. 6 is stored in advance in the building management system 16. For example, when the deviation between the target indoor temperature and the detected value of the indoor temperature sensor 12-1 becomes large, the characteristic map setting method reduces the contribution to the control of the indoor temperature sensor 12-1. In addition, the value of the weighting coefficient D1 when the deviation value is large is set to be less than 1.0. However, when the weighting coefficient D1 is set by the characteristic map of FIG. 6, the target room temperature has not yet been determined at the first execution of the temperature command value calculation routine, so the value of D1 is set to 1 only for the first time. Set to .0. If the characteristic map of FIG. 6 is used, the value of the weighting coefficient D1 can be set in consideration of not only the influence of the surrounding environment of the indoor temperature sensor 12-1 such as the presence or absence of a partition or a heating element but also the influence of changes in sunlight. . In the characteristic map of FIG. 6, the deviation may be calculated using an average value of detection values of the indoor temperature sensors 12-1 to 12-4 instead of the target indoor temperature.
[0033]
Next, the process proceeds to S8, where the average values of the respective weighting coefficients A1, B1, C1, and D1 calculated in S4 to S7 are calculated, and the total weighting coefficient K1 is calculated. Then, the process proceeds to S9, where the weighted room temperature M1 is calculated by multiplying the detected value of the indoor temperature sensor 12-1 by the total weighting coefficient K1. Next, the process proceeds to S10, and the value of the variable i is incremented by 1. In S11, whether or not the value of the variable i is larger than the number of indoor temperature sensors 12-1 to 12-4 (4 in the present embodiment). Determine.
[0034]
If NO in S11, the process returns to S3, S3 to S10 are executed for the other indoor temperature sensors 12-2, and each weighting coefficient A2, B2, C2, D2, total weighting coefficient K2, and weighting room temperature M2 are calculated. , S3 to S10 are executed for all the indoor temperature sensors 12-1 to 12-4.
[0035]
S3 to S10 are executed for all the indoor temperature sensors 12-1 to 12-4. If YES in S11, the process proceeds to S12, the average values of the weighted room temperatures M1, M2, M3, and M4 are calculated, and the target Calculate the room temperature. As a result, the target indoor temperature is calculated by considering the weights of the detected values of the indoor temperature sensors 12-1 to 12-4 at the respective positions. However, in order to treat the average value of the weighted room temperatures M1, M2, M3, and M4 as the target room temperature, the average value of all the weighting coefficients (16 in this embodiment) is set to 1.0. Next, the process proceeds to S13, where the target room temperature command value is output to the temperature controller 22, and the execution of this routine is terminated.
[0036]
In this routine, the average value of the weighting coefficients A1, A2, A3, and A4 (the same applies to B, C, and D) may not be 1.0. For example, the weighting method based on the date is controlled. In order to reflect it, the values of the weighting factors A1, A2, A3, and A4 may be set so that the average value of the weighting factors A1, A2, A3, and A4 by month and day is 1.0 or more. Thereby, the optimum weighting coefficient can be set in consideration of the influence degree of a plurality of weighting methods.
[0037]
In the present invention, a plurality of indoor temperature sensors are installed in the office, the detection values of the indoor temperature sensors at each position are weighted, and the weighted room temperature at each position is calculated. A target room temperature is calculated based on the weighted room temperature. The weighting method for the indoor temperature sensor is based on the partition between the office position and the indoor temperature sensor, the heating element, the temperature in the vicinity of the indoor temperature sensor due to the influence of the heating element, sunshine and outside air temperature, etc. The weighting is performed in consideration of a plurality of factors that cause deviations and also considering the weighting for each factor. Therefore, for indoor temperature sensors that are not affected by changes in partitions, heating elements, sunshine, and outside air temperature, etc., and for indoor temperature sensors that you want to reflect in the control command, set a higher weight, and change the partition, heating element, sunshine, and outside temperature. For indoor temperature sensors that you do not want to be reflected in the control command, you can set the weighting low, so that the temperature control accuracy of the office position can be improved without imposing an excessive burden on the air conditioner equipment administrator. Can be improved.
[0038]
In the present embodiment, the case where the present invention is applied to control the temperature in the office has been described, but the same effect can be obtained even when applied to the control of the temperature in a computer room or the like. . Furthermore, in the embodiment of the present invention, the case where the air conditioner is controlled using four temperature sensors has been described. However, the number of temperature sensors actually matches the size and application of the air-conditioned space. Changed. Moreover, the setting range of each weighting coefficient is not limited to 0.0-2.0, and may be set arbitrarily.
