针对目前桥载空调恒定送风所造成的客舱内舒适性差及节能效果不理想问题,以波音737客舱为研究对象,采用CFD方法建立客舱仿真模型,并通过实验验证了所建立的CFD客舱仿真模型的合理性。在此模型基础上,研究桥载空调不同送风速度对客舱内温度场、风速场及NOx浓度场的影响,并分别拟合出客舱空气分布特性指标(ADPI)、排污效率与桥载空调送风速度的函数关系,再根据ADPI、排污效率构建评价函数,得到桥载空调的优化送风速度,该送风速度能够为桥载空调机组的节能控制提供依据。
Aiming at the problem of poor comfort and energy-saving in the cabin caused by the constant air supply in the bridge air-conditioners, the CFD method is used to establish the cabin simulation model based on the Boeing 737 cabin, and the CFD cabin simulation model The rationality. Based on this model, the influences of different air supply speeds on the temperature, wind speed and NOx concentration in the cabin are studied. The ADPI, cabin air-conditioning efficiency Wind speed, then the evaluation function is constructed according to ADPI and blowdown efficiency, and the optimal blowing speed of bridge air conditioners is obtained, which can provide the basis for energy saving control of bridge air conditioners.
