Description

本発明は、空調制御システムに関するものである。   The present invention relates to an air conditioning control system.

近年、温暖化による省エネルギーの社会的要求が高まっている。現在の省エネルギー法は、民生部門に対して、機器単体の省エネルギー性能の向上だけでなく、ＢＥＭＳ（Building and Energy ManagementSystem）などを利用した管理面での省エネルギーも義務付けている。   In recent years, social demands for energy conservation due to global warming are increasing. The current energy conservation law obliges the consumer sector not only to improve the energy conservation performance of individual devices, but also to conserve energy in terms of management using BEMS (Building and Energy Management System).

しかし、ビル管理の実態として、ビル管理者は必ずしも快適性および省エネルギーの観点から冷房、暖房等の空調装置を適切に運用しているわけではない。特に、省エネルギーと快適性とが複雑に関係する居住空間の温熱環境管理（例えば、温度管理）に関しては、管理の容易さから慣習的な目標温度を設定し、温熱環境を享受する利用者からのクレームによって設定値を変更する場合が一般的である。   However, as the actual situation of building management, the building manager does not always operate air conditioning devices such as cooling and heating appropriately from the viewpoint of comfort and energy saving. In particular, with regard to thermal environment management (for example, temperature management) of living spaces where energy saving and comfort are intricately related, a customary target temperature is set for ease of management, and it is received from users who enjoy the thermal environment. Generally, the set value is changed according to a claim.

つまり、建物や居住者の特性を十分に考慮しないで温度管理を行うため、居住空間は必ずしも利用者の快適な状態に保たれず、さらには空調装置で消費されるエネルギーの無駄が発生する場合がある。また、利用者はビル管理者の管理する温熱環境下におり、自己の温熱環境をコントロールできないことに対して不満がある利用者もいる。   In other words, because temperature management is performed without fully considering the characteristics of the building or occupants, the living space is not necessarily kept in a comfortable state for the user, and furthermore, waste of energy consumed by the air conditioner occurs. There is. In addition, some users are dissatisfied with being unable to control their own thermal environment because they are in a thermal environment managed by the building manager.

このような空調制御の温度管理がもたらす問題に対して、利用者の温熱環境に対する要望を各個人が操作するパーソナルコンピュータ端末（以下、パソコンと称す）からリアルタイムで収集し、収集された各要望に基づいて目標温度を設定する方法があり、利用者が要望する温熱環境と目標温度とをリアルタイムに関連付け、時々刻々と変化する利用者特性や、居住空間の実際の温度と検出温度との差などの各建物の特性に応じて温熱環境を変化させることを可能にしている。（例えば、特許文献１参照）。
特開２００４−２０５２０２号公報 In response to the problems caused by temperature management of air conditioning control, users' requests for thermal environment are collected in real time from personal computer terminals (hereinafter referred to as personal computers) operated by each individual. There is a method to set the target temperature based on the relationship between the thermal environment desired by the user and the target temperature in real time, the user characteristics that change from moment to moment, the difference between the actual temperature of the living space and the detected temperature, etc. It is possible to change the thermal environment according to the characteristics of each building. (For example, refer to Patent Document 1).

本実施形態のシステムに用いる空調設備装置１は、図２（ａ）に示すように冷凍機（冷却塔）或いはボイラからなる熱源（図示せず）から冷温水の形態で空調機器室１００内に設置した空調機１０１と、空間Ａ内に配設したダクト１０２と、吹出口１０４とからなる空調設備で構成され、空調機１０１内で空気の加熱、冷却（空気との熱交換）を行い、この熱交換された空気を、ダクト１０２を通じて環境制御対象のフロアたる空間Ａに設けられた十数カ所の吹出口１０４から空間Ａ内に給気するようになっている。還気については空間Ａの中央通路より空調機器室１００に向け破線で示す還気経路１０５を確保し、同時に外気を混合し、空気調和を実施する空調設備を用いている。この空調設備では、空調機１０１が給気温度を変更し、室内温度を制御するようになっている。   As shown in FIG. 2A, the air conditioning equipment 1 used in the system of the present embodiment is installed in the air conditioning equipment room 100 in the form of cold / hot water from a heat source (not shown) consisting of a refrigerator (cooling tower) or boiler. It consists of an air conditioner consisting of an installed air conditioner 101, a duct 102 disposed in the space A, and an outlet 104, and heats and cools air (heat exchange with air) in the air conditioner 101, The heat-exchanged air is supplied into the space A from the dozen or more outlets 104 provided in the space A that is the floor of the environment control target through the duct 102. As for the return air, an air conditioner is used that secures a return air path 105 indicated by a broken line from the central passage of the space A toward the air conditioning equipment room 100, mixes the outside air at the same time, and performs air conditioning. In this air conditioning equipment, the air conditioner 101 changes the supply air temperature and controls the room temperature.

ここで本実施形態の温熱環境制御対象の空間Ａは、例えばオフィスのフロアであり、この空間Ａには図２（ｂ）に示すように机１０６が多数配置され、これら各机が個人個人により使用されるようなっている。このような空間Ａにおいて、温熱環境を享受する利用者使用の机上のパーソナルコンピュータたる入力装置３は、サーバ装置４内の図示しないＷＥＢサーバにアクセスし、環境情報を入力するためのコンテンツを当該ＷＥＢサーバから取得することで、要望情報入力手段３１を実現している。図示例では全ての入力装置３は通信ネットワークＮＴを介して、サーバ装置４との交信可能なシステムが構築されているものとし、サーバ装置４と入力装置３との間で、要望情報入力手段３１を実現する一般的なブラウザソフトが稼動する。各入力装置３は、環境情報を入力する際に対象となる空調設備装置１の空調番号（当該空調設備装置１の空調エリアを特定する番号）とユニークな識別情報（例えば、個人名もしくはメールアドレス等）が入力され、環境情報Ｉｎｆは、該ユニークな識別情報および空調番号とともにサーバ装置４に引き渡される。   Here, the thermal environment control target space A of the present embodiment is an office floor, for example, and a large number of desks 106 are arranged in the space A as shown in FIG. It has come to be used. In such a space A, the input device 3 which is a personal computer on the desk used by the user who enjoys the thermal environment accesses a WEB server (not shown) in the server device 4 and inputs content for inputting environmental information to the WEB. By obtaining from the server, the request information input means 31 is realized. In the illustrated example, it is assumed that a system capable of communicating with the server device 4 is constructed for all the input devices 3 via the communication network NT, and the request information input means 31 is provided between the server device 4 and the input device 3. General browser software that realizes Each input device 3 has an air conditioning number (a number that identifies the air conditioning area of the air conditioning equipment 1) and unique identification information (for example, an individual name or an e-mail address) of the air conditioning equipment 1 as a target when inputting environmental information Etc.) and the environmental information Inf is delivered to the server device 4 together with the unique identification information and the air conditioning number.

サーバ装置４は本実施形態のシステムの中枢を構成するものであり、データ取得のタイミング等を有し、各入力装置３が起動して環境情報を入力するためのコンテンツが自動的に立ち上がると、この立ち上がりに対応して当該入力装置３に対して、必要なデータを提供する機能を備えている。   The server device 4 constitutes the core of the system of the present embodiment, has data acquisition timing, etc., and when each input device 3 is activated and content for entering environment information is automatically started, A function of providing necessary data to the input device 3 corresponding to the rising is provided.

つまり環境情報を入力するためのコンテンツは入力装置３が起動すると自動的に立ち上がる設定となっており、立ち上がりと同時にサーバ装置４に対して入力装置３はアクセスを行い、自身の起動を示す信号（識別情報）を送るとともに、質問形式のフォーマットなど必要な情報をサーバ装置４側から取得する。なお、入力装置３が自身の起動を示す信号をサーバ装置４へ送信する構成は、上記構成に限定されるものではない。   That is, the content for inputting the environment information is set to automatically start when the input device 3 is activated, and the input device 3 accesses the server device 4 at the same time when the input device 3 is activated, and a signal ( Identification information) is sent, and necessary information such as a question format is acquired from the server apparatus 4 side. Note that the configuration in which the input device 3 transmits a signal indicating its activation to the server device 4 is not limited to the above configuration.

図３は入力装置３の起動後のモニタ画面を示しており、当該入力装置３の利用者が現在の空間Ａの温度に対する要望を示す要望情報Ｉｎｆを入力する画面であって、「温度を上げてほしい」、「温度を下げてほしい」という温度への要望を各々選択して入力する画面であって、該当する要望に対応するチェック欄Ｃ１，Ｃ２をマウス等のポインティングデバイスを用いてチェックし、送信釦Ｂ１をクリック操作することにより、その時点での特定の利用者の要望情報Ｉｎｆが自己の識別情報、空調番号とともにサーバ装置４へアップロードされる。また、この要望情報Ｉｎｆを入力する画面は、入力装置３の起動時だけでなく、利用者の操作またはサーバ装置４からの指示によって、任意のタイミングで入力装置３に当該画面を表示させることができる。   FIG. 3 shows a monitor screen after the input device 3 is activated. The user of the input device 3 inputs request information Inf indicating a request for the temperature of the current space A. This is a screen for selecting and inputting a request for temperature such as “I want you to lower the temperature”, and check the check fields C1 and C2 corresponding to the request using a pointing device such as a mouse. When the transmission button B1 is clicked, the request information Inf of the specific user at that time is uploaded to the server device 4 together with the self identification information and the air conditioning number. Further, the screen for inputting the request information Inf can be displayed on the input device 3 at an arbitrary timing not only when the input device 3 is started but also by a user operation or an instruction from the server device 4. it can.

要望情報取得手段４１は、利用者が使用する各自の入力装置３にインストールされたブラウザソフトクライアントソフトを利用して、当該サーバ装置４側へ送信された要望情報Ｉｎｆを収集して、履歴記憶手段４４に書き込む処理を行う。利用者の入力装置３から通信ネットワークＮＴを通じて送信される情報については、発信された入力装置３の識別情報から、どの利用者が、何時、空間Ａのどの位置において発信したものかを外部記憶装置に格納している個人情報及び識別情報並びに識別情報に対応付けてある入力装置３の配置情報とに基づいて特定するようになっており、上述の要望情報Ｉｎｆと識別情報および空調番号とを対応付けて履歴記憶手段４４に格納される。   The request information acquisition means 41 collects the request information Inf transmitted to the server apparatus 4 side by using browser software client software installed in each input device 3 used by the user, and stores history information. The process of writing to 44 is performed. For information transmitted from the user's input device 3 through the communication network NT, an external storage device indicates which user has transmitted at what position in the space A from the transmitted identification information of the input device 3. Is specified based on the personal information and the identification information stored in the ID, and the arrangement information of the input device 3 associated with the identification information, and the above-mentioned request information Inf is associated with the identification information and the air conditioning number. In addition, it is stored in the history storage means 44.

このようにして入力装置３から収集された要望情報Ｉｎｆに対して、サーバ装置４の制御計画立案手段４３は、履歴記憶手段４４内に格納されている要望情報Ｉｎｆと、データベース４２内に格納されている判断基準ルールとを読み出し、「温度を上げてほしい」、「温度を下げてほしい」という相反する二つの要望情報数の利用者総数に対する割合（要望率）を算出し、この要望率の割合を判断基準ルールに照らし合わせる合意形成ロジックによって目標温度Ｔｏを決定する。ここで、空調設備装置１は空間Ａを冷房しており、「温度を上げてほしい」という要望は消費エネルギーを低減させる要望情報であり、「温度を下げてほしい」という要望は消費エネルギーを増加させる要望情報である。なお、利用者総数は、起動している入力装置３の台数や、図示しない入退室管理装置によってカウントされた空間Ａ内の利用者の人数によって求められる。   For the request information Inf collected from the input device 3 in this way, the control plan drafting means 43 of the server device 4 is stored in the database 42 and the request information Inf stored in the history storage means 44. And calculate the ratio (request rate) to the total number of users of the two conflicting demand information such as “I want you to raise the temperature” and “I want you to lower the temperature”. The target temperature To is determined by the consensus building logic that compares the ratio with the criterion rule. Here, the air-conditioning equipment 1 is cooling the space A, and the request to “increase the temperature” is request information to reduce the energy consumption, and the request to “decrease the temperature” increases the energy consumption. It is request information to be made. The total number of users is determined by the number of activated input devices 3 and the number of users in the space A counted by an entrance / exit management device (not shown).

データベース４２内に格納されている判断基準ルールは、図４に示すように、縦軸に「温度を上げてほしい」とする要望率を、横軸に「温度を下げてほしい」とする要望率をとり、両方の要望率１００％の点を結ぶ線と、「温度を上げてほしい」が６５％、「温度を下げてほしい」が３５％の点から０点を結ぶ線と「温度を下げたい」が０％の縦軸とで囲まれた領域を目標温度上昇領域「▲」とし、両方の要望率１００％の点を結ぶ線と、「温度を上げてほしい」が３５％、「温度を下げてほしい」が６５％の点から０点を結ぶ線と、「温度を上げてほしい」が０％の横軸とで囲まれた領域を目標温度下降領域「▼」とし、これら目標温度上昇領域「▲」と目標温度下降領域「▼」とで挟まる領域を目標温度維持領域「■」と設定している。但し申告が少ない場合にはその環境に対して利用者が不満を持っていないものとして利用者総数に対して「温度を下げてほしい」要望率が第１の基準値Ｋ１以下、「温度を上げてほしい」要望率が第２の基準値Ｋ２以下の領域も目標温度維持領域「■」と設定している。この判断基準ルールにおいて、第１の基準値Ｋ１、第２の基準値Ｋ２は、後述する省エネ目標監視装置５による省エネ目標達成度ΔΦによって変化する。   As shown in FIG. 4, the determination criteria rule stored in the database 42 is a request rate that “the temperature is desired to be increased” on the vertical axis and a request rate that “the temperature is desired to be decreased” on the horizontal axis. Take the line connecting both points with a request rate of 100% and the line that connects the zero point from the point where 65% wants to raise the temperature and 35% wants the temperature to fall. The area surrounded by the vertical axis of 0% is designated as the target temperature rise area “▲”, the line connecting both points with the desired rate of 100%, “I want to raise the temperature” is 35%, “Temperature The area surrounded by the line connecting the 65% point to the 0 point and the "Want to increase the temperature" line with the 0% horizontal axis is the target temperature drop region "▼". A region sandwiched between the rising region “▲” and the target temperature decreasing region “▼” is set as the target temperature maintaining region “■”. However, if the number of declarations is small, it is assumed that the user is not dissatisfied with the environment, and the request rate of “I want to lower the temperature” is less than or equal to the first reference value K1, and the The area where the request rate is less than or equal to the second reference value K2 is also set as the target temperature maintenance area “■”. In this determination criterion rule, the first reference value K1 and the second reference value K2 vary depending on the energy saving target achievement degree ΔΦ by the energy saving target monitoring device 5 described later.

制御計画立案手段４３は、省エネ目標監視装置５によるエネルギー消費の監視結果を用いて、上記判断基準ルールによる合意形成処理を行っており、具体的には図５のフローチャートに沿って処理を行う。まず、省エネ目標監視措置５において、省エネ目標設定手段５２は、本システムの管理者が設定した省エネルギーの目標値Φ１を読み込み（ステップＳ１）、エネルギー監視手段５３は、空調設備装置１から取得した実際の消費エネルギーＥを読み込む（ステップＳ２）。そして、省エネ目標達成度算出手段５１は、過去の同じ時期の実績から推定される所定期間（例えば、1ヶ月）の消費エネルギーＥｏと実際の消費エネルギーＥとから、省エネルギー度［Φ２＝（Ｅｏ―Ｅ）／Ｅｏ］を算出し（ステップＳ３）、次に省エネ目標達成度［ΔΦ＝Φ２−Φ１］を算出する（ステップＳ４）。   The control plan drafting means 43 uses the result of monitoring the energy consumption by the energy saving target monitoring device 5 to perform consensus formation processing according to the above-mentioned criteria rule, and specifically performs processing according to the flowchart of FIG. First, in the energy saving target monitoring measure 5, the energy saving target setting means 52 reads the energy saving target value Φ1 set by the administrator of this system (step S 1), and the energy monitoring means 53 is actually acquired from the air conditioning equipment 1. Is read (step S2). Then, the energy saving target achievement degree calculation means 51 calculates the energy saving degree [Φ2 = (Eo−) from the consumed energy Eo for a predetermined period (for example, one month) estimated from the past results of the same period and the actual consumed energy E. E) / Eo] is calculated (step S3), and then the energy saving target achievement degree [ΔΦ = Φ2-Φ1] is calculated (step S4).

そして、サーバ装置４において、開始温度決定手段４５は、図６に示すように、算出した省エネ目標達成度ΔΦが高ければ、消費可能なエネルギーに余裕があると判断して、開始温度Ｔｓを快適方向（冷房時は温度を下げる方向）に設定し、省エネ目標達成度ΔΦが低ければ、消費可能なエネルギーに余裕がないと判断して、開始温度Ｔｓを省エネルギー方向（冷房時は温度を上げる方向）に設定する。そして、開始温度Ｔｓの情報を空調制御装置２へ送信し、空調制御装置２の目標温度Ｔｏとして開始温度Ｔｓを設定すると、空調制御装置２は、空間Ａ内の温度を測定する室温センサ２ａを備えており、室温センサ２ａが計測した温度計測データが、目標温度Ｔｏ＝Ｔｓに一致するように空調設備装置１を制御する（ステップＳ５）。したがって、開始温度Ｔｓの設定を省エネ目標達成度ΔΦに基づいて行うので、効率よく省エネ目標達成度ΔΦを向上させることができる。   In the server device 4, the start temperature determination unit 45 determines that the energy that can be consumed has a margin if the calculated energy saving target achievement degree ΔΦ is high, as shown in FIG. 6, and makes the start temperature Ts comfortable. If the energy saving target achievement degree ΔΦ is low, it is determined that there is no room for energy that can be consumed, and the start temperature Ts is set in the energy saving direction (in the direction of increasing the temperature during cooling). ). Then, when information on the start temperature Ts is transmitted to the air conditioning control device 2 and the start temperature Ts is set as the target temperature To of the air conditioning control device 2, the air conditioning control device 2 uses the room temperature sensor 2a that measures the temperature in the space A. The air conditioning equipment 1 is controlled so that the temperature measurement data measured by the room temperature sensor 2a matches the target temperature To = Ts (step S5). Therefore, since the start temperature Ts is set based on the energy saving target achievement degree ΔΦ, the energy saving target achievement degree ΔΦ can be improved efficiently.

次に、制御計画立案手段４３は、上記図４の判断基準ルールにおける第１の基準値Ｋ１、第２の基準値Ｋ２を、省エネ目標監視装置５が算出した省エネ目標達成度ΔΦによって設定する（ステップＳ６）。これは、図７（ａ）（ｂ）に示すように、省エネ目標達成度ΔΦが低ければ、消費エネルギーを増加させる要望情報の採用基準である第１の基準値Ｋ１を増大させ、消費エネルギーを低減させる要望情報の採用基準である第２の基準値Ｋ２を低減させて、省エネルギー方向への制御を行いやすくする。一方、省エネ目標達成度ΔΦが高ければ、消費エネルギーを増加させる要望情報の採用基準である第１の基準値Ｋ１を低減させ、消費エネルギーを低減させる要望情報の採用基準である第２の基準値Ｋ２を増大させて、快適方向への制御を行いやすくする。   Next, the control plan drafting means 43 sets the first reference value K1 and the second reference value K2 in the determination criterion rule of FIG. 4 according to the energy saving target achievement degree ΔΦ calculated by the energy saving target monitoring device 5 ( Step S6). As shown in FIGS. 7 (a) and 7 (b), if the energy saving target achievement degree ΔΦ is low, the first reference value K1 that is the adoption standard of the request information for increasing the energy consumption is increased, and the energy consumption is reduced. The second reference value K2, which is the adoption criterion for the desired information to be reduced, is reduced to facilitate control in the energy saving direction. On the other hand, if the energy saving target achievement degree ΔΦ is high, the first reference value K1 that is the adoption standard of the request information that increases the energy consumption is reduced, and the second reference value that is the adoption standard of the request information that reduces the consumption energy. Increase K2 to facilitate control in the comfort direction.

そして、要望情報取得手段４１は、各入力装置３からの要望情報Ｉｎｆを履歴記憶手段４４に順次格納し（ステップＳ７）、制御計画立案手段４３は、利用者毎に最新の要望情報Ｉｎｆを履歴記憶手段４４から抽出して有効データとし（ステップＳ８）、これらの要望情報Ｉｎｆの有効データから要望率を算出して、上記図４の判断基準ルールの領域と要望率とに基づいた合意形成ロジックにより目標温度Ｔｏを決定する（ステップＳ９）。つまり、図４の判断基準ルールに上述の算出した要望率をプロットし、そのプロットする位置が■の範囲の場合には現在の目標温度Ｔｏを維持し、▼の場合には、現在の目標温度Ｔｏから所定値（例えばΔｔ＝０．５℃）下げた温度を新たな目標温度Ｔｏとし、▲の範囲内にあれば、現在の目標温度Ｔｏから所定値（例えばΔｔ＝０．５℃）上げた温度を新たな目標温度Ｔｏとする（ステップＳ１０）。この目標温度Ｔｏの導出後、制御計画立案手段４３は、空調の制御内容を入力装置３で表示するためのフィードバック情報を更新する（ステップＳ１１）。   Then, the request information acquisition unit 41 sequentially stores the request information Inf from each input device 3 in the history storage unit 44 (step S7), and the control plan planning unit 43 records the latest request information Inf for each user. It is extracted from the storage means 44 as valid data (step S8), a request rate is calculated from the valid data of these request information Inf, and a consensus building logic based on the determination criterion rule area and the request rate of FIG. Thus, the target temperature To is determined (step S9). That is, the above-calculated desired rate is plotted in the determination criterion rule of FIG. 4, and the current target temperature To is maintained when the plotted position is in the range of ■, and in the case of ▼, the current target temperature To A temperature that is lower than To by a predetermined value (for example, Δt = 0.5 ° C.) is set as a new target temperature To. The new temperature is set as a new target temperature To (step S10). After deriving the target temperature To, the control plan drafting unit 43 updates the feedback information for displaying the control content of the air conditioning by the input device 3 (step S11).

このように、合意形成ロジックによって利用者の要望に基づく目標温度Ｔｏを設定して快適性を維持しながら、合意形成ロジックに用いる第１，第２の基準値Ｋ１，Ｋ２を省エネ目標達成度ΔΦに基づいて設定することで、省エネルギーを考慮しながら制御計画を修正して目標温度Ｔｏが設定されるので、快適性と省エネルギー化の両立が可能となる。   In this way, the first and second reference values K1 and K2 used for the consensus building logic are set to the energy saving target achievement degree ΔΦ while maintaining the comfort by setting the target temperature To based on the user's request by the consensus building logic. Since the target temperature To is set by correcting the control plan while considering energy saving, it is possible to achieve both comfort and energy saving.

そして、新たな目標温度Ｔｏ（目標温度Ｔｏ＝目標温度Ｔｏ±Δｔ）は履歴記憶手段４４に格納されるとともに、目標温度Ｔｏの情報を空調制御装置２へ送信して、空調制御装置２に新しい目標温度Ｔｏを設定する処理を行い（ステップＳ１２）、この処理後ステップＳ１に戻って以後システムの運転が停止されるまで、上述の省エネ目標達成度ΔΦを用いた目標温度Ｔｏの合意形成処理を繰り返す（但し、ステップＳ５の開始温度Ｔｓの決定処理は省略される）。空調制御装置２は、室温センサ２ａが計測した温度計測データが、上記決定された目標温度Ｔｏに一致するように空調設備装置１を制御する。   Then, the new target temperature To (target temperature To = target temperature To ± Δt) is stored in the history storage means 44, and information on the target temperature To is transmitted to the air conditioning control device 2 so that the air conditioning control device 2 has a new information. A process for setting the target temperature To is performed (step S12), and after this process, the process of returning to step S1 and performing the consensus formation process for the target temperature To using the above-described energy saving target achievement degree ΔΦ until the system operation is stopped. Repeat (however, the process of determining the start temperature Ts in step S5 is omitted). The air conditioning control device 2 controls the air conditioning equipment 1 so that the temperature measurement data measured by the room temperature sensor 2a matches the determined target temperature To.

また、図５中の破線に示すように、ステップＳ６における第１の基準値Ｋ１、第２の基準値Ｋ２の設定を、省エネ目標達成度ΔΦだけでなく、目標温度Ｔｏにも基づいて設定すれば、効率よく省エネ目標達成度ΔΦを向上させることができる。この場合、上記省エネ目標達成度ΔΦに基づく第１、第２の基準値Ｋ１，Ｋ２の設定処理に加えて、現在の目標温度Ｔｏが消費エネルギーの大きい値であれば、消費エネルギーを増加させる要望情報の採用基準である第１の基準値Ｋ１を増大させ、消費エネルギーを低減させる要望情報の採用基準である第２の基準値Ｋ２を低減させて、省エネルギー方向への制御を行いやすくする。また、この目標温度Ｔｏによる第１、第２の基準値Ｋ１，Ｋ２の設定処理は、目標温度Ｔｏの代わりに外気温度を用いても同様に構成できる。   Further, as indicated by the broken line in FIG. 5, the setting of the first reference value K1 and the second reference value K2 in step S6 is set based on not only the energy saving target achievement degree ΔΦ but also the target temperature To. Thus, the energy saving target achievement degree ΔΦ can be improved efficiently. In this case, in addition to the setting processing of the first and second reference values K1 and K2 based on the energy saving target achievement degree ΔΦ, if the current target temperature To is a value with large energy consumption, a request to increase the energy consumption. The first reference value K1, which is the information adoption standard, is increased, and the second reference value K2, which is the requirement information adoption standard for reducing energy consumption, is reduced, thereby facilitating control in the energy saving direction. The setting process of the first and second reference values K1 and K2 based on the target temperature To can be similarly configured even when the outside air temperature is used instead of the target temperature To.

なお、上記実施形態では、空調設備装置１が空間Ａを冷房している場合について主に例示しているが、空調設備装置１が空間Ａを暖房する場合は、「温度を上げてほしい」という要望が消費エネルギーを増加させる要望情報Ｉｎｆとなり、「温度を下げてほしい」という要望が消費エネルギーを低減させる要望情報Ｉｎｆとなり、冷房時と同様に処理できる。   In addition, in the said embodiment, although mainly illustrating about the case where the air conditioning equipment 1 is cooling the space A, when the air conditioning equipment 1 heats the space A, "I want you to raise temperature." The request becomes request information Inf for increasing the energy consumption, and the request “I want to lower the temperature” becomes the request information Inf for reducing the energy consumption, and can be processed in the same manner as during cooling.
