GB 50189—2015《公共建筑节能设计标准》管道与设备绝热厚度的修订

Piping and equipment insulation thickness revision in GB 50189-2015 Designstandardforenergy efficiencyofpublicbuildings

GB 50189—2005《公共建筑节能设计标准》至今已发布执行10年了。随着国家节能工作的深入开展、暖通空调技术的发展和能源价格的提升,原有的节能设计标准中关于管道与设备绝热条文的内容已不能满足使用的需求。为此,本次修编依据介质温度、能源价格、气候条件、绝热材料等不同条件,对暖通空调和给排水工程中常用的冷热管道和设备提出绝热要求,其适用范围更广、划分更细。

GB 50189-2005 Design standard for energy efficiency of public buildings has been issued for 10 years. With the in-depth development of national energy saving work, the development of HVAC technology and rising of energy price, the terms on piping and equipment insulation in original energy design standard can not meet the actual demand. Therefore, the revision is based on different conditions, such as medium temperature, energy price, climate conditions and insulation materials. In the HVAC and water supply and drainage project, proposes the insulation requirements for common used cooling and heating pipes and equipments, and these requirements are with more extensive application and more detailed division.
