摘要
针对《供热通风设计手册》中车间局部排风时消除余热所需机械送风量计算公式中存在的问题,通过车间热平衡和空气平衡,对推导较为科学的计算公式进行了有益的探讨。
In view of existing problems in calculating formula for mechanical ventilation needed for removing waste heat when local air exchange of workshop in ＂Heat Supply Ventilation Handbook＂, the scientific calcu- lating formula derived was discussed through thermal equilibrium and air balance in workshoo.
