对建筑节能有特殊要求的外墙外保温建筑的室内墙面露点温度的计算

The Calculation of Indoor Metope Dew Point Temperature of Building Exterior Insulation Construction With Special Requests for Energy-Efficient

由于使用功能的需要,室内的采暖空调设备对建筑节能保温方面提出了一些特殊要求,且这些要求均高于国颁《公共建筑节能设计标准》(GB50189—2005)中对建筑物外围护结构按常规节能保温标准处理的要求。若外围护结构处理不当,极有可能在室内墙面产生冷凝水,将大大降低节能保温的效果,影响使用。该文详尽地介绍了在实际工程中,按常规节能计算并满足外围护结构节能保温要求后,判断室内墙面是否出现冷凝水的验算过程和方法。

Due to the needs of functional use, some special requirements are published for indoor heating air conditioning equipment on building energy-saving isolation aspects. And these requirements are higher than the national standard of 〈public building energy efficiency design standard〉 （GB50189-2005） Building envelope. According to the requirements of the conventional standards of energy-saving preservation processing, it is most likely that condensate will appear if mishandled, which might greatly reduce the effect of energy-saving preservation and affect the use. In this thesis, checking process and methods of estimate are detailed introduced in the practical engineering that whether appears condensation water during conventional energy- saving calculation or after the requirements of energy-saving were reached.
