ABSTRACT

In this paper, aiming at the special environment of aircraft maintenance workshops required, taking a certain aircraft maintenance workshop in Shandong as an example, this paper analyzes the characteristics of radiant floor heating and ceiling radiant heating temperature field formed. Research presents the radiant floor heating and radiant heating roof coupling approach in the aircraft maintenance workshop, which eliminates the asymmetry of the single radiant heating methods, and effectively solves the problem of big color change due to big temperature gradient in the painting, paint withdrawal process of the plane. It is very important for enhancing the level of aircraft maintenance, so as to ensure the safe operation of the aircraft.

4. 结论

1) 使用地板辐射供暖的机库室内温度分布比较均匀，工作区的温度梯度较小，为1℃/m，机库顶端由于大空间对流换热，温度梯度较大。

2) 采用顶板辐射采暖的机库内，温度分层现象明显，顶部温度梯度较大，工作区整体温度较地板辐

3) 应该采用地板辐射供暖与顶板辐射供暖相互结合的方式，这样就会使整个机库的温度场分布均匀。尽管机库内的飞机体型庞大，但也能使喷漆、退漆的过程都处在较为稳定的温度环境中，可有效消除辐射的不对称性，从而不会导致飞机机身的色彩变化。
