摘　　要：本文根据热湿分段处理空调系统的特点,以TRNSYS为仿真平台,建立了热湿分段空调系统的仿真模型,分析了高温表冷器进水温度和不同表冷器排数设置对系统性能的影响。结果表明:在每个给定的排数设置下,热湿分段处理空调系统的节能率随高温表冷器进水温度的升高先增大后减少,在高温表冷器进水温度为19℃时均能取得最大值。在此基础上对排数比分别为1:3型,2:2型和3:1型三种方案进行了研究,得出在排数比为3:1型时节能率最大,最高可达18.7%。此结果为热湿分段空调系统的优化提供了理论支撑。In this paper, according to the characteristics of the segmented handling air conditioning system, the simulation model of the segmented handling air-conditioning system is established by TRNSYS. In order to research the operating characteristics and law of segmented handling air conditioning system, simulate with variable rows set and raising the chilled water supply temperature. The results showed that： on each certain rows set, the energy-saving rate of the segmented handling air-conditioning system first increase then reduce as the chilling water increasing, it obtains a maximum value when the chilling water temperature is 19℃.On that basis, further study three kinds of schemes, such as 2：2, 1：3, 3：1. The results showed that on 3：1 type row set can obtain the high test energy saving rate is 18.7%. The results provide support for the optimizing of the segmented handling air-conditioning.
