一般机械加工车间工艺流水大都是自东向西,在西端常有装配横跨。上海某厂一高大朝西横跨,1960年建造,大面积西侧窗,西阳眩光,炎夏车间温度上升,通风不好,异常闷热,严重影响生产,只好将大面积西窗涂上深蓝油漆,这仅能减弱西阳照射,但解决不了温度和通风不好等问题。近年上海某厂一装配横跨亦是朝西,36 Generally, the process flow in the machining workshop is mostly from east to west, and there are often assembly spans at the west end. A factory in Shanghai straddled the west and was built in 1960. There was a large area of ​​the west window. The glare of Xiyang, the temperature in the summer workshop rose, the ventilation was not good, and it was extremely sultry, which seriously affected the production. The large area west window had to be painted with dark blue paint. This can only weaken the Xiyang radiation, but can not solve the problem of poor temperature and ventilation. In recent years, an assembly plant across Shanghai is also facing west, 36
