摘要
针对工程中出现的新风管结露现象,为了确定新风管是否需要保温,运用传热学理论,采用试算法求解出了青岛地区新风管保温的临界条件.通常情况下,空调机房内的温度达到10℃甚至以上,就要考虑新风管保温,由此得出在一定的室外气象条件及室内温湿度条件下,为了防止新风管结露,有必要对新风管进行保温处理.
In reaction to the condensation of vapor of the flesh air duct in constructions, and in hopes of determine whether it is necessary for the flesh air duct to be insulated, based on the heat transfer science theories, and by means of tentative calculation to educe the critical temperature for fresh air duct insulation in Qingdao. In most cases, it is necessary to prepare the new air duct insulation, when the temperature in air conditioning computer room is 10℃ or even higher. Consequently, it is necessary to perform the insulation treatment for the flesh air duct in certain weather conditions.
