某高校图书馆分档调控空调新风量的节能分析

通过对某高校图书馆进行调研,发现馆内人数随时间具有显著的规律,据此提出基于室内人数实时确定新风量和分档控制的节能策略。为了证实该控制策略的可行性,采用DeST软件模拟不同工况下空调能耗状况。结果表明,新风量分档控制运行下空调能耗相较设计工况降低40%左右,在一定程度上实现空调系统节能,为内部人数呈现明显规律的大型公共建筑空调系统节能运行设计提供新思路。

Research on energy-saving of step adjusting fresh air volume of air-conditioning system in one university library

According to a survey conducted for one university library,it is found that population in the library changes in a pattern over time. Based on it,it is proposed to deter- mine the fresh air volume according to population in the library and adjust air volume in steps with the purpose of saving energy. In order to verify its feasibility, the energy con- sumption of the air-conditioning system under different operating conditions is simulated using software DeST. The results show that about 40% energy can be saved if adjusting the fresh air volume in steps. The data illustrates its feasibility and it can save energy of air-conditioning system to some extent. It provides an energy-saving idea for air-condition- ing system operating in large public buildings in which population changes in a pattern over time.
