この発明は、建物の各空調系統について、冬期における冷房用での空調機の使用に対する診断のための手法に関し、室内設定温度と冷水削減との関係の最適化を図る冬期冷房設定温度の最適化診断手法に関する。 The present invention relates to a method for diagnosing the use of an air conditioner for cooling in the winter season for each air conditioning system in a building, and is intended to optimize the relationship between the indoor set temperature and the reduction of chilled water. It relates to diagnostic methods.
地球環境問題の深刻化は、建物における省エネルギーやエネルギー効率の最適化を推進することを要求している。エネルギー削減を図る上において、種々のエネルギー効率の向上を図ることが要求される。このための手法として、ビルエネルギーマネジメントシステム（Building and Energy Management System、以下「BEMS」と略記する。）が導入され、建物の施設内における空調設備や照明設備等を対象として、室内環境や設備の状況を監視し、それらの運転制御を行うことによって、室内環境とエネルギー消費状況の最適化を図ることで、エネルギー削減が図られている。 Increasing global environmental issues require building energy conservation and energy efficiency optimization in buildings. In order to reduce energy, it is required to improve various energy efficiencies. For this purpose, a building energy management system (hereinafter abbreviated as “BEMS”) has been introduced, and air conditioning equipment and lighting equipment, etc. in the building facilities are targeted. By monitoring the situation and performing their operation control, the indoor environment and the energy consumption situation are optimized to reduce energy.
例えば、特許文献１には、建物で使用されるエネルギーの実績値を目標値以下にするためのビルエネルギー管理装置として、建物で使用されるエネルギーの現時点における実績値を入力し、入力された現時点の実績値と所定期間の目標値とを照合する照合手段と、照合手段による照合結果を月形式の累積グラフ、日形式の累積グラフまたは時間形式の累積グラフのいずれかで、前記所定期間の目標値に対する現時点の状況を表示部に表示させる表示制御手段と、を備えた構成が開示されている。
For example, in

また、特許文献３には、施設内の多数の計測器からの膨大な計測データに基づき所望の評価を行うためのグラフ表示が容易に行えるエネルギー管理システムのためのグラフ表示装置として、被計測対象に対して設けられた多数の計測器から得られる計測データに基づいて所望の評価を行うためのグラフ表示を入力手段と表示手段を使用してオペレータと対話的に行う施設内のエネルギー管理を行うエネルギー管理システムのためのグラフ表示装置であって、各軸にそれぞれ計測名称又は時間軸が規定された所望の評価を行うための予め作成された多種の元グラフを格納した元グラフ格納手段と、上記各計測器から送られてくる計測データを蓄積して格納する計測データ蓄積格納手段と、上記元グラフ格納手段に格納されたグラフ一覧表を表示してオペレータに使用するグラフの選定を促す手段と、オペレータにより選定された元グラフの計測名称に関する上記計測データ蓄積手段に格納された計測データを表示しオペレータに上記元グラフの各軸に設定する計測データの選定を促す手段と、上記選定された元グラフおよび計測データによるグラフ表示の実行の指示をオペレータに促しこれに対する指示に従って表示を行うグラフ表示手段と、を備えた構成が開示されている。 Further, Patent Document 3 discloses a measurement target as a graph display device for an energy management system that can easily perform a graph display for performing a desired evaluation based on a large amount of measurement data from a large number of measuring instruments in a facility.

ところで、ビルディング（以下「ビル」と略記する。）の管理を専門に行うビル管理会社等では複数のビル等の建物について管理を行っており、それぞれの建物について室内環境とエネルギー効率の最適化を図ることが行われている。この種のエネルギー効率の最適化のために、例えば特許文献１に記載されたエネルギー管理装置では、所定期間の目標値が設定され、この目標値と実績値とを照合した照合結果を月形式の累積グラフ等で表示させることが行われている。
By the way, building management companies that specialize in building management (hereinafter abbreviated as “buildings”) manage multiple buildings, etc., and optimize the indoor environment and energy efficiency for each building. Things are going on. In order to optimize this kind of energy efficiency, for example, in the energy management device described in
他方、ビルの室内環境等の最適化を図るためには、それぞれの室について個別にそれぞれの室内環境等を把握する必要がある。また、ビルの立地等によっても室内環境等が異なるから、複数の建物の管理を行っているビル管理会社等は、個別のビル毎についてそれぞれの室の室内環境等を把握することが必要となる。そして、把握した室内環境等のデータをもとにして、室内環境やエネルギー効率の最適化を図るための空調設備や照明設備等の運転の調整を行うことになる。 On the other hand, in order to optimize the indoor environment of a building, it is necessary to grasp the indoor environment of each room individually. Also, because the indoor environment differs depending on the location of the building, etc., building management companies that manage multiple buildings need to understand the indoor environment of each room for each individual building. . Then, based on the grasped data such as the indoor environment, the operation of the air-conditioning equipment and the lighting equipment for adjusting the indoor environment and energy efficiency is adjusted.
ビル管理会社等は、把握した室内環境やエネルギー効率の最適化を図るための空調設備等の運転調整について、建物の所有者に対して説明する。このとき、所有者の理解が容易となるような資料を必要とする。 The building management company, etc., explains to the owner of the building how to adjust the operation of the air conditioner and the like to optimize the grasped indoor environment and energy efficiency. At this time, it is necessary to have materials that make it easier for the owner to understand.
ところで、例えば、冬期には日光が差し込む日向側の部分と差し込まない日陰側の部分では温度差が生じ、日向側の部分では冬期であっても空調機が冷房運転される。この冬期の空調機の運転については、冬期であるので冷房のための冷水の使用の適否を判断することによってエネルギー効率の向上を図ることができる。しかし、前述した通り、それぞれの室等につていは個別の環境下にあるため、エネルギー効率の最適化を図る上においては、各室や当該ビルに配されている空調系統について個別に判断する必要が生じる。特に、室内温度と設定温度との関係を把握することによって、冷水使用の適正化を評価する指標を得ることができる。 By the way, for example, in winter, a temperature difference occurs between a portion on the sunshine side where sunlight is inserted and a portion on the shade side where it is not inserted, and the air conditioner is air-cooled in the portion on the sunshine side even in winter. Since the operation of the air conditioner in the winter season is in the winter season, it is possible to improve energy efficiency by determining whether or not to use the cold water for cooling. However, as described above, each room is in a separate environment, so when optimizing energy efficiency, the air conditioning system in each room or building is individually judged. Need arises. In particular, by grasping the relationship between the room temperature and the set temperature, it is possible to obtain an index for evaluating the appropriate use of cold water.
そこで、この発明は、多くの建物にBEMSが導入されていることに着目して、BEMSで得られた各種の計測データをもとにして、当該建物における空調装置の冬期の使用、特に冬期冷房設定温度の最適化診断手法を提供することを目的としている。 Therefore, the present invention pays attention to the fact that BEMS is introduced in many buildings, and based on various measurement data obtained by BEMS, the winter use of the air conditioner in the building, in particular, the winter cooling The purpose is to provide an optimization diagnosis method for the set temperature.
前記目的を達成するための技術的手段として、この発明に係る冬期冷房設定温度の最適化診断手法は、一つの建物についてBEMSにより得られた各種データを処理して、判断の対象となる期間について、当該建物についての空調時平均室温度を横軸に、冷熱量を縦軸に設定して、それぞれの空調系統についての値を描画した空調時室温冷熱量散布図と、横軸に空調系統のそれぞれを設定し、縦軸の一方に温度を、他方の縦軸に月積算空調時冷熱量を設定して、空調系統毎の冷熱量の棒グラフを冷熱量の順に並べて、それぞれの空調系統についての月平均室温と設定温度と夜間平均室温とを描画した各系統空調状態図とを用いて、前記空調時室温冷熱量散布図によって、冷熱量が多く室温が低い値が多い建物ほど設定温度に不具合がある空調系統の多い建物と判断し、前記各系統空調状態図によって、冷熱量が多く室温度が低い空調系統を特定し、当該時の設定温度と室温度とを比較し、夜間室温を疑似自然室温にして参考にしながら設定温度の上昇幅を推測して対策検討系統を明確化することを特徴としている。 As a technical means for achieving the above object, the optimization diagnosis method for the winter cooling set temperature according to the present invention is to process various data obtained by BEMS for one building and determine the period to be judged. , the air conditioning when the average room temperature for the building on the horizontal axis, by setting the cold calorie vertical axis, and the air conditioning at room temperature the cold calorie scatter diagram values drawing a for each of the air conditioning system, the horizontal axis of the air-conditioning system Set each one, set the temperature on one of the vertical axes, set the monthly total air-conditioning cold energy on the other vertical axis, arrange the bar graph of the cold heat amount for each air conditioning system in order of cold heat amount, for each air conditioning system Using the air conditioning room temperature diagram showing the monthly average room temperature, set temperature, and night average room temperature, the building has a higher cold heat and lower room temperature in the air conditioning room temperature cold energy scatter diagram. There is an air conditioning system Judgment that there are many buildings, identify the air conditioning system with a large amount of heat and low room temperature, compare the set temperature and room temperature at that time, and use the room temperature at night as a pseudo natural room temperature for reference However, it is characterized by clarifying the countermeasure study system by estimating the rise of the set temperature.
多くの建物に導入されているBEMSで得られた各種の計測データをもとにするものであり、一つの建物について、前記BEMSによって各室の設定温度と室温、空調装置の発停情報、冷熱(水)量、についてのデータを採取する。これらのデータのうちの冷熱(水)量と発停情報による空調装置の運転時の平均室温度とを描画して、前記空調時室温冷熱量散布図を作成する。この空調時室温冷熱量散布図を参照して冷熱量が多く、しかも室温が低い値のプロットが多いほど、設定温度に不具合がある空調系統が多数存在する建物であると判断する。この判断は個々の建物についての冬期冷房設定温度が最適にあるか否かを判断するものであり、該当する建物についての空調系統を評価することはできない。この空調系統の評価に前記各系統空調状態図を利用する。 It is based on various measurement data obtained by BEMS installed in many buildings. For one building, the set temperature and room temperature of each room, air conditioner on / off information, cooling / heating Collect data on (water) volume. Of these data, the amount of cold heat (water) and the average room temperature during operation of the air conditioner based on the start / stop information are drawn, and the air conditioning room temperature cold energy amount scatter diagram is created. With reference to this air-conditioning room temperature cold energy scatter diagram, as the amount of cold heat increases and the number of plots with low room temperature increases, it is determined that the building has a large number of air-conditioning systems with defective set temperatures. This determination is to determine whether or not the winter cooling set temperature for each building is optimal, and the air conditioning system for the corresponding building cannot be evaluated. Each system air conditioning state diagram is used for the evaluation of this air conditioning system.
前記各系統空調状態図では、室温度が低く冷熱量が多い空調系統について、冬期冷房系統推奨値に対して、当該時の設定温度と実際の室温度とを比較して、設定温度の上昇幅を推測して、当該空調系統の動作の適正化を図るようにする。 In each system air conditioning state diagram, for an air conditioning system with a low room temperature and a large amount of heat, compared with the recommended value for the winter cooling system, the set temperature at that time is compared with the actual room temperature, and the increase in the set temperature To optimize the operation of the air conditioning system.
また、請求項２の発明に係る冬期冷房設定温度の最適化診断手法は、任意の空調系統について横軸に時刻を、縦軸の一方にエネルギー値を、他方の縦軸に温度を設定し、冷温熱量と空調電力と照明電力エネルギー値と、空調時平均室温と夜間室温とを描画した各系統空調状態詳細図とを用いて、前記明確となった対策検討系統について、冬期の所望期間の状態を前記各系統空調状態詳細図に描画して、具体的対策の検討資料とすることを特徴としている。
Moreover, the optimization diagnosis method for the winter cooling set temperature according to the invention of
BEMSによって、例えばファン動力や照明電力等のデータを採取し、これらのエネルギー値を描画した前記各系統空調状態詳細図を作成する。この各系統空調状態詳細図は、対策を要すると判断された空調系統について、例えば12月〜２月等の冬期の任意期間について作成する。 For example, data such as fan power and illumination power is collected by BEMS, and the above-described detailed air conditioning state diagram of each system in which these energy values are drawn is created. This detailed air conditioning state diagram for each system is created for an arbitrary period in winter, such as December to February, for an air conditioning system that is determined to require countermeasures.
前記冷温熱量によって冬期冷房の度合いや時間帯を確認する。空調電力によって空調機稼働状態を確認し、照明電力によって在室者の有無等を推測する。室内温度によって冬期冷房度合いと空調停止時の室温上昇度合いを確認し、室設定温度と空調時平均室温、夜間室温とによって設定温度の改善幅を検討する。 The degree and time zone of winter cooling are confirmed by the amount of cooling and heating. The air conditioner operating state is confirmed by the air conditioning power, and the presence or absence of the occupant is estimated by the illumination power. Confirm the degree of cooling in winter and the rise in room temperature when air conditioning is stopped according to the room temperature, and consider the range of improvement in the set temperature based on the room set temperature, the average room temperature during air conditioning, and the room temperature at night.
また、請求項３の発明に係る冬期冷房設定温度の最適化診断手法は、判断の対象となる期間について、一つの建物についての月平均空調時室温設定温度を横軸に、月積算空調時冷熱量を縦軸に設定し、それぞれの空調系統についての値を描画した空調時室温設定冷熱量散布図を作成し、前記空調時室温冷熱量散布図によって、設定温度に不具合がある空調系統が多い建物との判断を行うに際して、前記空調時室温設定冷熱量散布図において、冷熱量が多く、室温度設定が低い値が多い建物ほど、設定温度に不具合がある空調系統が多い建物との判断の補助とすることを特徴としている。 In addition, the optimization diagnosis method for the winter cooling set temperature according to the invention of claim 3 is based on the monthly average air-conditioning room temperature setting temperature for one building for the period to be judged, and the monthly integrated air-conditioning cooling Set the amount on the vertical axis and draw the air conditioning room temperature setting cold energy scatter diagram in which the values for each air conditioning system are drawn, and there are many air conditioning systems that have problems with the set temperature by the air conditioning room temperature cold energy scatter diagram When making a determination as a building, in the air conditioning room temperature setting cold energy scatter diagram, a building with a large amount of cold heat and a low room temperature setting indicates that the building has many air conditioning systems with defective set temperatures. It is characterized by assisting.
この空調時室温設定冷熱量散布図を参照して、設定温度の不具合が多い空調系統が存在している建物を特定する。なお、実際の室温と設定温度との乖離が大きい場合もあるため、前記空調時室温冷熱量散布図の捕捉資料として利用する。 With reference to this air-conditioning room temperature setting cold energy scatter diagram, a building in which an air-conditioning system with a lot of preset temperature problems exists is identified. In addition, since the difference between the actual room temperature and the set temperature may be large, it is used as a capture material for the air-conditioning room temperature cold energy scatter diagram.
この発明に係る冬期冷房設定温度の最適化診断手法によれば、室内温度と設定温度とを、冷熱量、すなわち冷水使用量の多い空調系統順に明示した各系統空調状態図を用いて判断できるから、冬期冷房設定温度の適否の判断を容易に行える。この判断に基づいて冬期冷房設定温度の最適化を行って、エネルギー効率の向上を図ることができる。各種の図表に基づいて、設定温度に対する室内温度に関するエネルギー現況の理解を容易に、且つ、迅速に行うことができる。 According to the optimization diagnosis method for the winter cooling set temperature according to the present invention, the room temperature and the set temperature can be determined using each system air conditioning state diagram clearly showing the amount of cold heat, that is, the air conditioning system in which the amount of cold water used is large. Therefore, it is possible to easily determine whether or not the winter cooling set temperature is appropriate. Based on this determination, it is possible to optimize the winter cooling set temperature to improve energy efficiency. Based on various charts, it is possible to easily and quickly understand the current state of energy related to the room temperature with respect to the set temperature.
以下、図示した好ましい実施の形態に基づいて,この発明に係る冬期冷房設定温度の最適化診断手法を具体的に説明する。 In the following, based on the preferred embodiment shown in the drawings, the optimization diagnosis method for the winter cooling set temperature according to the present invention will be specifically described.
図１には任意の建物について、この発明に係る冬期冷房設定温度の最適化診断手法を実施するに際して使用する某年12月の空調時室温冷熱量散布図であり、横軸に空調時平均室温度が、縦軸には冷熱(水)量が設定される。そして、空調系統のそれぞれについてのこれらの値が描画されている。なお、同図において右側の塗り潰された円で示す直線は冷房系統の推奨値Ｒである。また、破線により囲まれた領域は不具合領域Ａを示している。 FIG. 1 is a scatter diagram of room temperature cold energy during air conditioning in December 2009 used when implementing the optimization diagnosis method for winter cooling set temperature according to the present invention for an arbitrary building.

In the figure, the straight line indicated by the filled circle on the right side is the recommended value R for the cooling system.
また、図３はこの発明に係る冬期冷房設定温度の最適化診断手法を実施するに際して使用する図１の空調時室温冷熱量散布図を描いた建物についての各系統空調状態図である。横軸には各空調系統が設定され、縦軸の一方には温度が、他方の縦軸には冷熱(水)量が設定される。そして、各空調系統毎の冷熱量の棒グラフを大きい順で並べて描画し、それぞれの空調系統に対応する月平均室温と設定温度、夜間平均室温とを描画してある。なお、図４には他の建物についての各系統空調状態図を例示してある。 FIG. 3 is an air conditioning state diagram of each system for the building depicting the air-conditioning room temperature cold energy scatter diagram of FIG. 1 used when carrying out the winter cooling set temperature optimization diagnosis method according to the present invention. Each air conditioning system is set on the horizontal axis, the temperature is set on one of the vertical axes, and the amount of cold (water) is set on the other vertical axis. Then, bar graphs of the amount of heat for each air conditioning system are drawn side by side in descending order, and the monthly average room temperature, the set temperature, and the nighttime average room temperature corresponding to each air conditioning system are drawn. In addition, in FIG. 4, each system air-conditioning state diagram about another building is illustrated.
また、図５は図３の各系統空調状態図を描いた建物についての各系統空調状態詳細図であり、横軸に時刻を、縦軸の一方にエネルギー値を、他方に温度を設定し、任意の空調系統について冷温熱量と空調電力と照明電力エネルギー値と、空調時平均室温と夜間室温とを描画してある。この場合の空調系統は、前記各系統空調状態図（図３）において対策を検討することが明確となった空調系統、すなわち対策検討系統について描画する。なお、図６は他の建物についての各系統空調状態詳細図を例示してある。 In addition, FIG. 5 is a detailed diagram of each system air conditioning state for the building depicting each system air conditioning state diagram of FIG. 3, with the time on the horizontal axis, the energy value on one of the vertical axes, and the temperature on the other, For any air conditioning system, the amount of cold / heat energy, air conditioning power, illumination power energy value, air-conditioning average room temperature and night room temperature are drawn. The air conditioning system in this case is drawn with respect to the air conditioning system for which the countermeasures are clearly considered in the respective system air conditioning state diagrams (FIG. 3), that is, the countermeasure examination system. In addition, FIG. 6 has illustrated each system | strain air conditioning state detailed drawing about another building.
以上のように作成された空調時室温冷熱量散布図と各系統空調状態図とを用いて、冬期冷房設定温度の適否の診断を行う。なお、前記空調時室温設定冷熱量散布図と前記各系統空調状態詳細図とは、診断に際して補助的に利用する。 The suitability of the winter cooling set temperature is diagnosed using the air-conditioning room temperature cold energy scatter diagram created as described above and each system air-conditioning state diagram. In addition, the air-conditioning room temperature setting cold energy scatter diagram and each system air-conditioning state detailed diagram are used supplementarily for diagnosis.
作成された図１に示す前記空調時室温冷熱量散布図を参照して、前記不具合領域Ａ内にプロットされた値の空調系統が多く存在する建物については、設定温度に不具合、不適当な空調系統が多い建物であると判断する。すなわち、この空調時室温冷熱量散布図では、当該建物が具備している空調系統のうち設定温度に不具合のある空調系統が多数存在していることが把握できる。 Referring to the created air-conditioning room temperature cold energy scatter diagram shown in FIG. 1, for buildings where there are many air-conditioning systems with the values plotted in the defective area A, the set temperature is defective and inappropriate air conditioning. Judged as a building with many systems. That is, in this air-conditioning room temperature cold energy scatter diagram, it can be understood that there are many air-conditioning systems having a malfunction in the set temperature among the air-conditioning systems provided in the building.
設定温度に不具合な空調系統が多数存在している建物について、図３に示すような前記各系統空調状態図を作成する。この各系統空調状態図では、冷熱(水)量の空調系統に係る棒グラフが、例えば多い順に並べられているため、室温度の低い空調系統を特定し易く、特定された空調系統について、当該時の設定温度と実際の室温度とを比較し、設定温度の上昇幅を推測する。この場合に、非空調時を夜間として夜間室温を疑似自然室温として参考にする。蓋し、室内温度が自然室温に近いほど空調エネルギーは少なくなると考えられるためである。この各系統空調状態図を用いることによって、冷熱量が順に並べられているから、対策を施すべき空調系統の優先順位を容易に把握できて、検討対象を確実にすることができる。 For a building where there are many air-conditioning systems having a problem with the set temperature, the above-described system air-conditioning state diagram as shown in FIG. 3 is created. In each system air conditioning state diagram, the bar graphs related to the air conditioning system of the amount of cold (water) are arranged in order of increasing numbers, for example, so that it is easy to identify an air conditioning system with a low room temperature. The set temperature is compared with the actual room temperature to estimate the increase in the set temperature. In this case, the nighttime room temperature is referred to as a non-air-conditioning time at night and the room temperature is referred to as a pseudo natural room temperature. This is because the air conditioning energy is considered to decrease as the room temperature approaches the natural room temperature. By using each system air-conditioning state diagram, since the amount of cold heat is arranged in order, the priority order of the air-conditioning system to which measures should be taken can be easily grasped, and the object to be examined can be ensured.
ところで、冬期冷房設定温度の最適化の判断指針としては、設定温度と冷熱量との関係を利用することも可能である。すなわち、図２に示すような、空調時室温設定冷熱量散布図を描いて、設定温度に不具合のある空調系統の有無は数を把握する。この空調時室温設定冷熱量散布図においても、冷熱量が多く、設定温度が低い値のプロットが多いほど設定温度不具合空調系統が多数存在していると判断できる。ただし、実際の室温と設定温度とが大きく乖離している場合があるため、この空調時室温設定冷熱量散布図は、前記空調時室温冷熱量散布図の捕捉資料として利用することが好ましい。 By the way, as a guideline for optimizing the winter cooling set temperature, it is also possible to use the relationship between the set temperature and the amount of cooling. That is, as shown in FIG. 2, a room temperature setting cold heat amount scatter diagram as shown in FIG. 2 is drawn, and the number of air conditioning systems having a defect in the set temperature is grasped. In this air-conditioning room temperature setting cold energy scatter diagram, it can be determined that there are a large number of preset temperature defective air conditioning systems as the amount of cold heat increases and the number of plots with a low set temperature increases. However, since the actual room temperature may be greatly different from the set temperature, it is preferable to use the air conditioning room temperature setting cold energy scatter diagram as a capture material for the air conditioning room temperature cold energy scatter diagram.
