Description

本発明は、複数のフロアを有しかつ各フロア毎に１つ又は複数の空調機と複数の空調エリアとを有する空調用建物について空調熱量及び消費電力を各空調エリアに按分する方法とシステムに関する。   The present invention relates to a method and system for distributing air conditioning heat and power consumption to each air conditioning area for an air conditioning building having a plurality of floors and one or more air conditioners and a plurality of air conditioning areas for each floor. .

複数のフロアや空調エリアを有する貸しビル等では、省エネルギーあるいはテナントの課金を目的として、空調エリア（単位区画又は単位個室）毎の空調熱量と消費電力の算出が求められる。複数の空調エリアを受け持つ空調機で構成されるシステムを採用した場合、
（１）各空調エリアの空調熱量を求める場合は、各空調エリアの吹き出し温湿度、吸い込み温湿度、吹き出し風量を計測する必要がある。
（２）各空調エリアの消費電力を求める場合は、各運転機器に電力量計を設置する必要がある。
しかしながら、（１）（２）で測定可能なのは機器単位での消費電力であり、エリア毎の消費電力ではなく、しかも各空調エリア毎にそれらの計測器を設置するには膨大なコストを必要とする。 In a rental building having a plurality of floors and air-conditioning areas, calculation of air-conditioning heat amount and power consumption for each air-conditioning area (unit section or unit private room) is required for the purpose of energy saving or tenant billing. When adopting a system consisting of air conditioners with multiple air conditioning areas,
(1) When calculating the air-conditioning heat quantity of each air-conditioning area, it is necessary to measure the blowing temperature / humidity, the suction temperature / humidity, and the blowing-air quantity of each air-conditioning area.
(2) When calculating the power consumption of each air-conditioning area, it is necessary to install a watt hour meter in each operating device.
However, what can be measured in (1) and (2) is the power consumption in units of equipment, not the power consumption for each area, and enormous costs are required to install these measuring instruments for each air conditioning area. To do.

特開平５−１１８９３１「熱量按分装置」には、水配管系からの測定を行わず気流系の測定値から潜熱を含めた全消費熱量の算出を可能とする熱量按分装置が記載されており、還気温度センサ、還気湿度センサ、給気温度センサ、給気風速センサ、還気エンタルピと給気エンタルピとの差と給気風量とから全熱量を算出する制御手段とを包含している。このシステムでは高価な測定器を多数必要とするためイニシャルコストが膨大なものとなる。Japanese Patent Application Laid-Open No. 5-118931 describes a calorific apportioning device that enables calculation of the total heat consumption including latent heat from the measured value of the air flow system without performing measurement from the water piping system. A return air temperature sensor, a return air humidity sensor, a supply air temperature sensor, a supply air speed sensor, and a control means for calculating the total heat quantity from the difference between the return air enthalpy and the supply air enthalpy and the supply air quantity. Since this system requires many expensive measuring instruments, the initial cost is enormous.

特開２０００−２７４７７７「水方式空調機器の課金システム」には、空調機器の消費エネルギー量から空調料金を算出する水方式空調機器課金システムが記載され、水方式の空調機器、熱源機器、計測器、課金管理機器を包含し、冷温水バルブの開時間及び開度制御量に基づく運転量から消費エネルギー量を按分算出し、空調料金を算出している。このシステムでは消費エネルギー量の算出を冷温水バルブの開度だけに依存しているため、公平な熱量と消費電力が按分して算出されないという欠点がある。Japanese Patent Application Laid-Open No. 2000-274777 “Billing system for water-type air-conditioning equipment” describes a water-type air-conditioning equipment billing system for calculating an air-conditioning charge from the amount of energy consumed by the air-conditioning equipment. In addition, accounting management equipment is included, and the amount of energy consumed is calculated proportionally from the amount of operation based on the opening / closing time of the cold / hot water valve and the opening control amount, and the air conditioning charge is calculated. In this system, since the calculation of the energy consumption depends only on the opening of the cold / hot water valve, there is a disadvantage that the fair amount of heat and power consumption are not calculated equally.

特開２００４−１４４３４８「エリア別空調制御システム」には、エリア情報を受ける入力部、空調制御部、演算部を包含し、空調制御部がエリア情報に応じて空調機から吹き出される空気流を制御し、演算部が制御の内容を勘案して空調装置の消費エネルギー量をエリアそれぞれに按分するシステムが記載されている。このシステムでは、各計量ポイント毎に流量計、風速計、風量計が必要となりイニシャルコストが膨大なものとなる。Japanese Patent Application Laid-Open No. 2004-144348 “Air-conditioning control system by area” includes an input unit that receives area information, an air-conditioning control unit, and a calculation unit. A system is described in which a control unit calculates the energy consumption of an air conditioner for each area in consideration of the contents of the control. In this system, a flow meter, an anemometer, and an air flow meter are required for each measuring point, and the initial cost is enormous.

本発明の目的は、空調制御の制御信号と必要最低限の計測器により、空調熱量及び消費電力をできるだけ公平に按分するシステムを提供することにある。   An object of the present invention is to provide a system that apportions air conditioning heat amount and power consumption as fairly as possible by using a control signal for air conditioning control and a minimum necessary measuring instrument.
