针对轿车空调车室内的温度场分布特性,在理论分析并结合实验测量和数值模拟的基础上,提出简捷而较可靠的动态经验公式。该经验公式考虑环境温度、太阳辐射、空调送风参数和人体等诸多影响因素后,可以计算在任意时刻下的轿车空调车室内的任意空间点处的温度值。其结果与实验测量和数值模拟的结果进行了比较,具有一定的可靠实用性,而计算量则大为简化,有利于在线预测和进行随后的热舒适性的自适应模糊控制。
According to the distribution of temperature field in a car air-conditioned car room, a simple and reliable dynamic empirical formula is proposed based on theoretical analysis and experimental measurement and numerical simulation. The empirical formula takes into account the environmental temperature, solar radiation, air-conditioning air supply parameters and the human body and many other factors, you can calculate the car at any moment under the car air-conditioned room at any point of the temperature value. The results are compared with the experimental and numerical results, which are reliable and practicable. However, the computational complexity is greatly simplified, which is conducive to on-line forecasting and subsequent adaptive fuzzy control of thermal comfort.
