HEAT SOURCE CONTROL SYSTEM

PROBLEM TO BE SOLVED: To simplify a secondary load state by processing "water amount" and "heat amount" different in physical unit as percentages being handled under the same index.SOLUTION: A total value of a load flow rate measurement value of a secondary-side cooling water system and an assumed value of a bypass flow rate, is divided by a total value of a designed flow rate of a heat source to calculate a cold water load flow rate ratio displayed by percentage, a load heat amount measurement value of the secondary-side cold water system is divided by a total value of a designed heat amount of the heat source to calculate a cold water load heat amount ratio displayed by percentage, a larger value of the cold water load flow rate ratio and the cold water load heat amount ratio is applied as a cold water load factor, and at least one of control of the number of heat sources and control of the flow rate of the heat source is implemented on the basis of the cold water load factor.SELECTED DRAWING: Figure 1 【課題】物理単位が異なる「水量」と「熱量」とを同じ指標に扱える百分率として処理することによって２次負荷状態を単純化することを可能とした。【解決手段】 ２次側冷水系統の負荷流量計測値とバイパス流量の想定値との合計値を、熱源の設計流量の合計値で除して百分率表示した冷水負荷流量比率を算出し、２次側冷水系統の負荷熱量計測値を、熱源の設計熱量の合計値で除して百分率表示した冷水負荷熱量比率を算出し、冷水負荷流量比率と冷水負荷熱量比率との何れか大きい値を冷水負荷率とし、冷水負荷率に基づいて、熱源の台数制御および熱源の流量制御の少なくとも一方を行う。【選択図】 図１
