摘　　要：在Matlab中搭建变风量空调系统自动控制程序,在DeST软件中对建筑进行建模,将计算得到的房间自然室温、建筑热特性系数作为自动控制程序的输入参数,进行房间温度、送风参数、空调负荷、设备能耗计算。结合案例,对典型房间室内温度、空调冷负荷、送风量、空调箱风机耗电功率进行模拟分析。室内温度、空调冷负荷、送风量、空调箱风机耗电功率变化趋势基本一致,变风量空调系统自动控制程序调节效果良好。空调箱风机平均耗电功率为0.26kW,与采用定风量空调系统相比,变风量空调系统可节省约44.6%的空调箱风机能耗。The automatic control program of variable air volume air conditioning system is built in Matlab,the building is modeled in DeST software,and the calculated room natural room temperature and building thermal characteristic coefficient are used as input parameters of the automatic control program to calculate the room temperature,air supply parameters,air conditioning load and equipment energy consumption.Combined with the case,the indoor temperature,air conditioning cooling load,air supply volume,and power consumption of the air conditioning box fan in a typical room are simulated and analyzed.The change trend of indoor temperature,air conditioning cooling load,air supply volume and power consumption of air conditioning box fan is basically the same,and the automatic control program of the variable air volume air conditioning system has a good adjustment effect.The average power consumption of the air conditioning box fan is 0.26 kW,and the variable air volume air conditioning system can save about 44.6%of the energy consumption of the air conditioning box fan compared to the constant air volume air conditioning system.
