摘　　要：直接采用冷却除湿方式对新风进行处理是温湿度独立调节空调系统潜热处理的主要形式。文章通过理论分析和实验测试的方法对预冷型新风机组的性能进行分析。结果显示,新风预冷段变工况运行和定工况运行均能满足温湿度独立控制的新风送风的含湿量要求。针对某办公建筑,当考虑水系统输配能耗时,预冷段变工况模式比定工况运行模式节能5.29%。Using cooling dehumidification method to handle fresh air directly is the main form of latent heat treatment in temperature and humidity independent control air conditioning system.The performance of pre-cooling fresh air unit is analyzed by theoretical analysis and experimental test.The results show that both varied and constant working conditions of fresh air pre-cooling section can satisfy the moisture content requirement of fresh air supply by temperature and humidity independent control.For an office building,considering the energy consumption of water system transmission,the energy saving of varied working condition is 5.29%higher than that of constant working condition in pre-cooling section.
