关于湿式地暖和干式地暖的区分,早在2013年发布的国家地暖标准JGJ142及施工图集12K404中就分得很清楚,就是施工过程中是否要水泥回填,采用普通保温板卡管固定并需要水泥回填湿法施工的就叫湿式地暖;相反,采用沟槽保温板地暖模块嵌管固定,无需水泥回填干法施工的叫干式地暖。

两者优缺点对比如下:

1,层高和载荷方面:干式地暖模块厚度3CM,自重2KG/平方,湿式地暖总成厚度10CM,自重120多KG/平方,两者相差5CM地面层高和120KG/平方载荷。

2,地暖效果方面:干式地暖采用铝板做均热层,导热率相对提高了140倍,均热能力大幅提高,相同热源下,干式地暖表面温度可提高5℃,房间温度提高3℃,特别是地板区热舒适度可大幅改善。

3,升温快慢使用便捷性方面:干式地暖相当于铺在地上的全铝板低温散热器,地暖惰性小升温快,表面升温时间半小时,可以像空调一样即开即用、特别适合上班族便捷地暖。

4,地暖运行费用方面:干式地暖既大幅提高了均热能力,又提高保温层厚度,大幅降低向楼下的传热损失约30%,白天关地暖可节省20%以上,所以铝板干式地暖平均可节省一半费用,这非常可观!

5,对地板安全保护方面:干式地暖保温板具有良好的防潮隔音功能,可保护地板防潮防霉防白蚁,回南天让地板家具安全!

湿式地暖不具备这个功能。

6,对夏天空调影响方面:干式地暖没有水泥层,地面绝热不吸收空调冷量,让夏天空调更加凉爽。

湿式地暖不具备这方面功能。

根据地暖标准JGJ142-2012.需要用豆石水泥回填的叫混凝土填充式地板采暖.简称湿式地暖;不需要水泥回填用地暖模块铺设的叫预制沟槽保温板地面采暖.简称干式地暖。所以按地暖末端结构技术分为湿式地暖和干式地暖.属于薄型地暖。

湿式地暖优点是价格低.比较舒适;
湿式地暖缺点:
1.总成厚度10公分需占一定层高;
2.升温慢蓄热时间长白天不能关.南方使用不便捷;
3.向下传热损失较大使用费相对较高;
4.水泥自重对高层建筑需校核载荷并加固地基;
5.前期铺设对地面装修有制约要求。
6.地暖管包裹在混凝土里.施工被打坏很难维修!

干式地暖优点:
1.总成5公分薄型不额外占层高.也不影响防盗门槛高度.与不装地暖层高一样;
2.升温快褪温适中.白天可关比较适合南方家庭;
3.节能省钱.干式地暖模块采用铝板快速传热散热.大幅减少了向下传热和白天围护损失.相对节能40%左右.这是铝板干式地暖最大优点!
4.干式地暖自重轻.对于南方高层建筑整装地暖是个大优点!铝板干式地暖自重2Kg/平方;而水泥回填自重150Kg/平方,所以南方高层建筑整装湿式地暖必须经载荷核校并加固地基.否则将成危房隐患!
5.地面温度高更舒适.铝板干式地暖表面平均提高5度.房间提高2度.适合南方高湿度地区。
6.装修中后期配合铺地砖地板施工.不制约装修.地暖管维修方便;
干式地暖缺点:成本略高.因为铝板比水泥贵,地面平整度要达到铺地板基本要求。
