【摘要】 根据能量守恒,建立了一个由空调房间、表冷器和冷水系统组成的暖通空调系统特性模型;在考虑了室外气候的变化和室内人员的变动情况下,对空调系统变水流量的比例积分(PI)控制以调节房间温度进行研究,分析控制参数对房间温度控制的影响。结果表明合理的控制参数选择取决于空调系统特性。更多还原

【Abstract】 Based on the energy conservation, a mathematical model of dynamic behavior of Variable Water Volume (VWV) air conditioning system was established. With the change of outside temperature and indoor persons, the control of temperature is based on adjusting chiller water flow rate. The selection of the parameters for a PI control system was simulated. The results show that the reasonable control parameters are determined by the behavior of air conditioning system.更多还原
