摘要： 针对中央空调系统的变风量与变水温协调运行的问题,建立了可同时进行变风量和变水温调节的空调系统的TRNSYS动态仿真模型,并利用实验证明了模型的准确性。通过控制末端风量模拟不同负荷率下变水温运行对空调系统的影响,得出该空调系统在不同负荷率下的最佳供水温度,制定了变风量空调系统随时间变水温运行策略,并与定水温工况进行对比。结果表明：在工作时段该变风量空调系统变水温模式运行能保证房间舒适性,且相对定水温运行模式,在整个模拟周期内系统总体能耗节省5.88%。

Abstract: Aiming at the problem of coordinated operation between VAV (variable air volume) and variable water temperature in central air conditioning system, a TRNSYS dynamic simulation model of air conditioning system with adjustable air supply and water supply temperature is established, and the accuracy of the model is proved by experiments. By controlling the terminal air volume to simulate the effect of variable water temperature operation on the air conditioning system under different load rates, the optimal water supply temperature of the air conditioning system under different load rates is obtained, and the variable water temperature operation strategy of the VAV air-conditioning system at different time periods is formulated, and compared with the constant water temperature operation conditions. The results show: compared with the constant water temperature mode, the variable water temperature mode of the VAV air-conditioning system can ensure the comfort of the room during the working period, and the overall energy consumption of the system can be saved by 5.88% in the whole simulation cycle.
