自然通风率的测量原理及热损失的计算

Measurement Principles of Natural Ventilation Rate and Calculation of Heat loss

自然通风热损失对建筑物的空调设计和能量审计是非常重要的。本文首先介绍了自然通风率的测量原理,然后,笔者根据气体分子运动论和热力学理论,导出了由自然通风引起的热损失的计算公式。

The heat loss caused by natural ventilation is very important for energy audit and air-conditioning design of buildings. In this paper, the measurement principles of natural ventilation rate is presented firstly, and then the formula for calculating heat loss is derived from the molecular kinetic theory of perfact gas by author.
