风口风压对空调系统新风控制影响的仿真研究

The research of wind pressures's effect on the control of outside air flow

通过仿真实验研究风口风压对空调系统摄入新风量的影响，根据结果得出无论是定风量还是变风量系统，用固定风门的方法将无法保证系统所需的新风量，建议根据风口风压和负荷的情况对新风风门进行调整，以保证最小新风量并尽可能节能。

By simulation experiments on the effects of outside wind pressure on the intake fresh air flow in for-conditioning system, the results that fixed damper can not guarantee the required fresh air flow no matter in VAV or CAV systems are demonstrated. Regulation of OAD based on the situation of outside wind pressure and the load is suggested, in order to ensure the Mini- mum fresh air flow and energy saving.
