Description

本発明は、省エネルギー効果算出装置に関し、たとえば、空気調和機、冷凍・冷蔵ショーケースなどの気象条件により消費電力量が変化する設備の更新あるいは改善による省エネルギー効果を算出する省エネルギー効果算出装置に関するものである。   The present invention relates to an energy saving effect calculating device, for example, an energy saving effect calculating device for calculating an energy saving effect by updating or improving a facility whose power consumption changes depending on weather conditions such as an air conditioner and a refrigeration / refrigeration showcase. is there.

近年、地球温暖化防止などの社会的要請から省エネルギーに対する意識が非常に高まり、省エネルギーを実現する設備、制御装置の導入および設備の運用方法の改善が盛んに行われている。このような状況下で重要なのは、省エネルギー効果を正しく算出することである。すなわち、空気調和機、ショーケースなどの設備の更新や、運用方法の改善をした場合に、どの程度、省エネルギーを実現したかを定量的に知ることが必要となる。特に、ESCO(Energy Service Company)など省エネルギー効果を保証する事業の拡大により、省エネルギー効果を正しく算出することが重要となっている。   In recent years, due to social demands such as the prevention of global warming, awareness of energy conservation has greatly increased, and the introduction of facilities and control devices for realizing energy conservation and improvements in the operation methods of facilities have been actively conducted. Under such circumstances, it is important to correctly calculate the energy saving effect. In other words, it is necessary to quantitatively know how much energy saving has been achieved when the equipment such as the air conditioner and the showcase is updated and the operation method is improved. In particular, it is important to correctly calculate the energy saving effect due to the expansion of businesses that guarantee the energy saving effect such as ESCO (Energy Service Company).

ところで、従来の省エネルギー効果の算出は、既存の設備の消費電力量と更新あるいは改善後の設備の消費電力量を比較することにより行われていた。ここで、空気調和機、ショーケースなどの設備については、外気温度、外気相対湿度などの気象条件により消費電力量が変化するので、その影響を多少加味し、更新あるいは改善前の前年同月の消費電力量、あるいは気象条件の近似した日の消費電力量と比較して、省エネルギー効果を算出することとしていた。しかし、前年同月の消費電力量と比較しても前年が暖冬であったり、冷夏であったりするので、気象条件を揃えることは困難であり、単純に、更新あるいは改善前の電力消費量と、更新あるいは改善後の電力消費量とを定量的に比較することはできない。   By the way, the conventional calculation of the energy saving effect has been performed by comparing the power consumption of the existing equipment with the power consumption of the equipment after the update or improvement. Here, for equipment such as air conditioners and showcases, the amount of power consumption varies depending on weather conditions such as outside air temperature and outside air relative humidity. Compared to the amount of power or the amount of power consumed on a day approximated by weather conditions, the energy saving effect was calculated. However, compared with the power consumption of the same month last year, it is difficult to make the weather conditions uniform because the previous year is warm winter or cold summer, and simply the power consumption before renewal or improvement, The power consumption after renewal or improvement cannot be quantitatively compared.

このような問題を解決するために、実運転と並行してシミュレーション運転を行うことにより、その差分から差分算出式を作成し、この差分算出式を用いて省エネルギー効果を求める省エネルギー効果算出装置が提案されている(たとえば、特許文献1参照)。しかし、この装置によれば、設備(プラント)の消費電力特性を模擬するシミュレータ(プラントモデル)を作成する必要があり、さらに、予め省エネルギー手段の適用時と非適用時の実験データおよび省エネルギー手段の適用時のシミュレーション結果から差分算出式を求めておくことが必要である。くわえて、設備の更新あるいは改善があった場合に、シミュレータおよび差分算出式を見直す必要があり、その精度の維持に多くの労力を要することになる。   In order to solve such a problem, an energy saving effect calculation device that creates a difference calculation formula from the difference by performing a simulation operation in parallel with actual operation and obtains an energy saving effect using the difference calculation formula is proposed. (For example, refer to Patent Document 1). However, according to this apparatus, it is necessary to create a simulator (plant model) that simulates the power consumption characteristics of the facility (plant), and in addition, experimental data when the energy saving means is applied and when the energy saving means is not applied and the energy saving means It is necessary to obtain a difference calculation formula from the simulation result at the time of application. In addition, when the equipment is updated or improved, it is necessary to review the simulator and the difference calculation formula, and much labor is required to maintain the accuracy.

また、シミュレータを作成せずに省エネルギー効果を算出するものとして、省エネルギー運転モードと基本運転モードとを有し、短時間の基本運転モードによる稼働に要した消費電力量から全期間を基本運転モードで稼働したと仮定した場合に要する消費電力量を求めるとともに、残余時間の省エネルギー運転モードによる稼働に要した消費電力量から全期間を省エネルギー運転モードで稼働したと仮定した場合に要する消費電力を求め、省エネルギー効果を算出する省エネルギー算出システムが提案されている(たとえば、特許文献2参照)。しかし、このシステムによれば、短時間であるとはいえ、省エネルギー運転モードで稼働可能な時間を基本運転モードで稼働しなければならないので、全期間を省エネルギー運転モードで稼働すれば得られるはずの省エネルギー効果を犠牲にすることになる。   In addition, the energy saving effect can be calculated without creating a simulator. The energy saving operation mode and the basic operation mode are provided, and the entire period is calculated from the power consumption required for operation in the short basic operation mode. Calculate the power consumption required when assuming that the system has been operated in the energy-saving operation mode from the power consumption required for operation in the energy-saving operation mode for the remaining time. An energy saving calculation system for calculating an energy saving effect has been proposed (see, for example, Patent Document 2). However, according to this system, although it is a short time, the time that can be operated in the energy saving operation mode must be operated in the basic operation mode, so it should be obtained if the entire period is operated in the energy saving operation mode. The energy saving effect will be sacrificed.

さらに、このような課題を解決して、省エネルギー効果を算出するものとして、設備の更新あるいは改善後の消費電力量と気象情報とから消費電力量と気象情報との関係式を求め、設備の更新あるいは改善前の気象情報とこの関係式とから設備の更新あるいは改善前の仮想消費電力量を求める。そして、設備の更新あるいは改善前の実消費電力量とこの仮想消費電力量とから省エネルギー率を求める。つづいて、この省エネルギー率に設備の更新後の消費電力量を乗じて、省エネルギー効果を算出する省エネルギー効果算出装置が提案されている(たとえば、特許文献3参照)。   Furthermore, in order to solve these problems and calculate the energy saving effect, the relational formula between the power consumption and weather information is obtained from the power consumption and weather information after updating or improving the equipment, and the equipment is updated. Alternatively, the virtual power consumption before the facility update or the improvement is obtained from the weather information before the improvement and this relational expression. And an energy saving rate is calculated | required from the actual power consumption before the update or improvement of an installation, and this virtual power consumption. Subsequently, there has been proposed an energy saving effect calculation device that calculates the energy saving effect by multiplying the energy saving rate by the power consumption after the facility update (for example, see Patent Document 3).

しかしながら、上述した省エネルギー効果算出装置は、気象条件によって省エネルギー効果が異なる設備の場合(たとえば、気温が高い場合に省エネルギー効果が小さく、気温が低い場合に省エネルギー効果が大きく、消費電力量と気象情報との関係式が当てはまらない場合)には、正確な省エネルギー効果を求めることができないことになる。   However, the energy saving effect calculation device described above is a facility that has different energy saving effects depending on weather conditions (for example, the energy saving effect is small when the temperature is high, the energy saving effect is large when the temperature is low, and the power consumption and weather information are In the case where the relational expression of (1) does not apply, an accurate energy saving effect cannot be obtained.

本発明は、上記実情に鑑みて、外気温度および外気相対湿度等の気象条件により消費電力量が変化する空気調和機、冷凍・冷蔵ショーケースなどの設備の更新あるいは改善であっても、気象条件の影響を排除して、正確に省エネルギー効果を算出することができる省エネルギー効果算出装置を提供することを目的とする。   In view of the above circumstances, the present invention is a renewal or improvement of equipment such as an air conditioner, a refrigeration / refrigeration showcase, etc. in which power consumption changes depending on weather conditions such as outside air temperature and outside air relative humidity. It is an object of the present invention to provide an energy saving effect calculating device that can accurately calculate the energy saving effect without the influence of the above.

これらの消費電力情報を累積した合計が200X年8月の気象条件に換算した設備更新後の消費電力量が求められることになる。このようにして求められた消費電力量は13000kWhである。そして、200X年8月の実際に消費した消費電力量14000kWhと求めた消費電力量13000kWhとの差1000kWhが200X年の気象条件における省エネルギー効果となる。   The sum of the accumulated power consumption information is calculated as the power consumption after the facility update in which the weather conditions of August 200X are converted. The power consumption thus obtained is 13000 kWh. The difference of 1000 kWh between the actual power consumption 14000 kWh actually consumed in August 200X and the calculated power consumption 13000 kWh is the energy saving effect in the 200X weather conditions.
