Dynamic Heat Load Computation of the Armored Vehicle Air Condition System

建立了装甲车辆的整体温度场的计算模型,提出了利用数值方法计算太阳辐射和发动机的散热对整个装甲车辆的整体温度场的影响,进而通过温度场计算空调热负荷的装甲车辆动态热负荷的计算方法.计算了一天之内的空调系统热负荷的变化情况,并讨论了太阳辐射强度和发动机负荷对空调热负荷的影响.

The model for calculating the whole temperature distribution of the armored vehicle is established , and the method for calculating the dynamic heat load of the armored vehicle air condition system is also put forward. The method is that the effects of the sun radiation and the engine heat dissipation on the temperature distribution of the armored vehicle is calculated through the numerical method, and the heat load of the air condition system is calculated by the use of the temperature distribution results. The variation of the dynamic heat load of the air condition system during a whole day is calculated. The effects of the sun radiation intensity and the engine load on the heat load of the air condition system are discussed.
