随着大空间生产厂房的兴建,当前热风采暖有着特别重要的意义。在兼有通风的生产、公用或附属房间内设计采暖时,通常要供给一定数量的热量,用以补偿热损失。在采暖计算中,关于直接确定工作区空气温度的方法,还没有人提出过任何有根据的建议。在向这些房间送风的方法中,用得最广泛的是采用水平射流送入上部区域或垂直向下送风。在向上部区域水平送风进行采暖时,排气方式很重要。通过排风井、天窗、屋顶排风机从上部区域排气时,由于沿屋盖扩散的 With the construction of large-scale production plants, the current hot air heating has a particularly important significance. When designing heating in ventilated production, utility or ancillary rooms, a certain amount of heat is usually supplied to compensate for heat loss. In the calculation of heating, no one has made any basis on the method of directly determining the air temperature in the work area. Among the methods of delivering air to these rooms, the most widely used is the use of horizontal jets to send into the upper area or vertically downwards. When the air is heated horizontally in the upper area, the exhaust method is very important. When exhausting from the upper area through exhaust shafts, skylights, roof exhaust fans, due to diffusion along the roof
