变风量空调系统新风量控制中，传统的控制策略不能兼顾既满足多房间室内空气质量又充分减少新风负荷的要求。针对多房间 CO2浓度的控制要求，提出了一种通过在线预测稳态时房间 CO2浓度控制新风量的方法。通过实时预测各个空调房间稳态时的 CO2浓度，选择 CO2浓度最高的房间作为检测房间，控制其 CO2浓度为设定值，其他房间的 CO2浓度都小于设定值。给出了其理论依据和在线稳态预测的步骤。与新风比修正新风量控制方法的对比结果表明，该方法在保证多房间 CO2浓度满足要求的基础上有效减少了新风负荷。
變風量空調繫統新風量控製中，傳統的控製策略不能兼顧既滿足多房間室內空氣質量又充分減少新風負荷的要求。針對多房間 CO2濃度的控製要求，提齣瞭一種通過在線預測穩態時房間 CO2濃度控製新風量的方法。通過實時預測各箇空調房間穩態時的 CO2濃度，選擇 CO2濃度最高的房間作為檢測房間，控製其 CO2濃度為設定值，其他房間的 CO2濃度都小于設定值。給齣瞭其理論依據和在線穩態預測的步驟。與新風比脩正新風量控製方法的對比結果錶明，該方法在保證多房間 CO2濃度滿足要求的基礎上有效減少瞭新風負荷。

Traditional control strategies can not satisfy the demands of multi-room indoor air quality and reducing outdoor air load fully in outdoor air volume control of variable air volume air conditioning systems.According to the control requirements of multi-room CO2 concentration,proposes a control strategy of outdoor air volume based on the online prediction of steady room CO2 concentration.Through the real-time prediction of steady CO2 concentration in each air conditioning room,takes the room with the highest CO2 concentration as detected room and controls its CO2 concentration to meet the set value,while the CO2 concentration in other rooms is less than the set value.Presents the theoretical basis and steps of on-line steady prediction.Compared with the outdoor air ratio correction control method,the proposed control strategy can reduce the outdoor air load effectively on the basis of meeting the requirements of multi-room CO2 concentration.
