摘　　要：针对中、小型集中式空调系统大多时间处于部分负荷下运行的特点,提出了采用变水温DDC控制的方法实现空调系统的节能运行。通过实验验证了采用变水温DDC控制方法的可行性,并研究了不同负荷下采用变水温DDC控制所具有的室内温湿度控制效果和节能效果。Since the medium-small size central air-conditioning system is often operated under partial load, a method of variable chilled water temperature with DDC to realize energy conservation in air-conditioning system is proposed. The feasibihty of adopting the method of variable chilled water temperature with DDC is proved, and the control effect of room temperature and relative humidity and energy conservation effect by adopting variable chilled water temperature with DDC under different load is studied.
