热车间内自然通风量的确定

Determination of natural Ventilation Volume inside Hot workshop

分析了热车间内进行局部排风时消除车间余热所需自然通风量计算公式中存在的问题,通过车间内的热平衡和空气平衡,推导出了合理的公式,并进行了一些有关方面的探讨。

Through analyzing problems existing in calculation formula of natural ventilation volume required for eliminating work-shop rest heat when hot workshop is ventilated locally via workshop internal heat balance and air balance,it deduced out rational for-mula and discusses associated aspects.
