An Empirical Formula for Calculating the Temperature Field inside the Air-conditioned Automobile Compartment

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。

To study the temperature field distribution inside the air-conditioned automobile compartment, a theoretic method, experiments and the numerical simulation are adopted in the paper. As a result, a simplified and reliable dynamic empirical formula is derived, which takes many factors into consideration, such as atmosphere temperature, solar radiation, air-conditioner parameter and human body. It can calculate the temperature value in any position inside the compartment at any moment. The results are compared with that of the experiment and the numerical simulation. It is shown that the calculation is simple, has reliable result and can also help the on-line prediction, and then the adaptive fuzzy control for thermal comfort.
