中央空调是控制浮式生产储卸油装置（FPSO）生活楼内温度的重要设备，其主要由冷水机组及空气处理单元组成。通过阐述中央空调制冷特点及空气处理单元现有问题，分析了造成风机故障的不同类型，通过测量振动值、测量环境湿度、更换皮带选材、更换皮带型号的应用效果，为降低中央空调空气处理单元风机故障频次提供参考理论依据。

Central air conditioning is an important device for controlling the temperature in floating production storage offloading （FPSO） living quarters， mainly composed of chiller units and air handling units. By elaborating on the cooling characteristics of central air conditioning and the existing problems of air handling units， different types of fan failures were analyzed. By measuring vibration values， measuring environmental humidity， replacing belt materials， and changing belt models， the application effects were studied， providing a reference theoretical basis for reducing the frequency of fan failures in central air conditioning air handling units.
