中央空调系统大部分时间是在部分负荷下运行,而热湿分段处理空调系统在部分负荷下实现节能运行具有明显优势。在热湿分段处理空调系统实验台上进行了冷水机组串联运行的实验,研究了该系统在部分负荷下性能的变化规律。实验结果表明:在设计负荷相同时,热湿分段处理空调系统冷水机组串联运行时所能承受的最大负荷为常规空调系统的81?5%。当负荷百分比从81?5%降低到50%,热湿分段处理空调系统冷水机组平均COP由3?13提高到4?16,表明在部分负荷下,热湿分段处理空调系统具有较大节能潜力。

Air conditioning systems are usually operated under part load conditions, and segmented handling air-conditioning system has significant advantages of realizing energy-saving operation under part load conditions. Chillers in serial configuration was carried out on a test bed of segmented handling air-conditioning system, and the performance of system in different load conditions were studied. Experi-ment results show that:the maximum load that segmented handling air-conditioning system can handle is only 81. 5% compared with con-ventional systems when the design load is the same. When the load reduces from 81. 5% to 50%, the chillers of the system average COP increases from 3. 13 to 4. 16, which indicates that segmented handling air conditioning system can create a big energy saving potential un-der part load conditions.
