摘要：对北京大兴国际机场航站楼核心区空调水系统进行了水力平衡调适，对比了调适前后各机房回水温度一致性和典型区域的温差，通过工程实例阐述了经过水力平衡调适后的空调水系统可以表现出更好的运行性能；对比了2021、2022年核心区制冷季水系统平衡调适前后的空调系统能耗，发现调适后的系统能耗降低约24.9%。综合考虑室外温度、客流量及机组运行情况等参数对空调系统能耗的影响，比较了8月核心区空调系统能耗，结果表明，2022年8月核心区空调系统节能率约为14.4%,其中末端设备节能率约为13.3%,水泵节能率约为20.3%。

Abstract: The hydraulic balance commissioning of the air conditioning water system in the core area of Beijing Daxing International Airport terminal is carried out. The consistency of the return water temperature of each air conditioning plant room before and after the commissioning and the temperature difference in typical areas are compared. The engineering example illustrates that the air conditioning water system after the hydraulic balance commissioning can show better operation performance. The energy consumption of the air conditioning system before and after the hydraulic balance commissioning of the water system in the core area in the cooling season in 2021 and 2022 is compared, it is found that the energy consumption of the system after the commissioning is reduced by about 24.9%. In addition, considering the influence of the parameters such as outdoor temperature, passenger flow and unit operation on the energy consumption of the air conditioning system, the energy consumption of the air conditioning system in the core area in August is compared. The results show that in August 2022, the energy saving rate of the air conditioning system in the core area is about 14.4%, with the energy saving rate of the terminal equipment being about 13.3% and the energy saving rate of the water pump being about 20.3%.
