基于人体热舒适性的某雷达方舱空调系统设计

雷达方舱内电子设备多，且具有内部结构异常、空间狭小、相对密闭等特点。若人体热舒适性欠佳，长时间处于其中的人员就会感觉疲劳，精神恍惚，心情烦躁等，人员操作的可靠性就会降低。空调系统是方舱内环控的主要设备。文中在确定空调选型的前提下，从人体热舒适性出发，着重考虑送风风道出风口的风速和风道风阻，应用数值模拟与现场试验测试相结合的方法，确定风道形式及其布局以及出风口数量。结果表明，应用该方法，方舱内温度分布均匀，出风口风速合理，热舒适性得到了明显改善。

Design of Air Conditioning System for a Radar Cabin Based on Human Thermal Comfort

The radar cabin, with a lot of electronic equipment in it, is characterized by abnormal internal structure, small and relatively closed space. If human thermal comfort is not good, the operator in it for a long time will suffer from fatigue, trance, irritability, etc., and thus the reliability of personnel operation is reduced. The air conditioning system is the main equipment for environmental control in the cabin. On the premise of determining the type of air conditioner, the wind speed at the air outlet and the wind resistance of air-duct are focused on from human thermal comfort. The type & layout of air-duct and the number of air outlets are determined by combination numerical simulation and field tests. The results show that the temperature distribution in the cabin is uniform, the wind speed at the air outlet is reasonable and the thermal comfort is significantly improved with this method.
