摘要
从民用机场建筑地理位置、建筑结构的特殊性，探讨机坪辐射现象对候机楼为主的民用机场建筑空调冷负荷的影响。宽阔、平坦的、大面积的停机坪在夏季强烈阳光照射下形成一个巨大的发射平面，与阳光共同形成机坪辐射。而这种辐射所形成的最大负荷与建筑物的温差传热最大值出现在同一时段，形成空调系统的高峰负荷。因此，机坪辐射对机场建筑空调冷负荷的影响应是一个不容忽视的因素。对于候机楼等机坪周边机场建筑的空调冷负荷、材料选择以及空调送风系统的布置等，除了考虑一般影响民用建筑空调冷负荷的因素外，应充分考虑机坪辐射的影响。
A civil airport consists of a complex of public buildings and an aircr aft parking apron. The wide, even parking apron of large area becomes a gigantic emitting su rface by the action of strong solar radiation in summer, resulting in the radiation from the parking apron. This will lead to the cooling peak load for air-conditioning in airport building s, which is simultaneous with the maximum temperature difference in- and outside the buildin gs. In this paper, the effect of radiation from aircraft parking apron on the coolin g load for air-conditioning in airport buildings was investigated in detail, in aspects of the geographical locations of civil airport buildings and the specific characteristics of buildin g structures. It was concluded that the influence of radiation from aircraft parking apron is imp ortant and must be considered in determining the cooling load for air-conditioning in build ings around the apron, selecting the materials, and laying out the distribution system for c ooling air.
