【Abstract】 Applying heat transfer theories,this paper develops equations for the calculation of air temperatures along ventilation ducts and methods for theoretical calculation of the ventilation duct heat transfer coefficient. Based on the measured data, practical equations for calculation of the ventilation duct heat transfer are also derived through regression analysis.更多还原
