摘要
基于能量守恒定律和变风量空调房间的热工特性,建立了变风量空调房间室温变化动态响应数学模型,并分析了引起室温滞后响应的影响因素。通过阶跃响应试验获得了室温对风量调节机构的滞后动态响应特性。建立了室温对各执行机构滞后响应的辨识模型,通过Simulink对辨识模型进行了仿真。结果表明,辨识模型拟合度较高,可以较好地反映室温滞后响应特性。
Based on the energy conservation law and the thermal characteristics of variable air volume(VAV)air conditioning room,establishes a mathematical model of VAV room temperature dynamic response,and analyses the influencing factors of the room temperature hysteresis response.Obtains a hysteretic response characteristics of room temperature to airflow rate regulating actuators by step response tests.Establishes a hysteresis response identification model of room temperature to regulating actuators,and simulates the identification model by Simulink.The results show that the identification model has a higher fitting degree and can reflect the hysteresis response characteristics of room temperature well.
