四种计算方式在低温热水地板采暖设计应用上的对比

Four Kinds of Calculation Methods on Low Temperature Hot Water Floor Heating Design

低温热水地板辐射采暖在我国发展速度较快,主要是在地面装饰层下布置热水管,然后通过地面将水管热量散发出去,提高室内的舒适温度;通过对欧洲标准EN1264、ASHRAE手册、日本《温水地板供暖系统设计施工手册》及国家行业标准JGJ 142—2004提供的4种计算方式的应用,对比其中的优劣、难易程度;提出一些建议,为同行选择该采暖方式时提供计算依据。

Low temperature hot water floor radiant heating system has developed rapidly in China, which is mainly arranged under the surface decoration layer with hot water pipe and the pipe heat emitted by the sucface, improving the indoor comfort temperature; Four kinds of calculation methods and application are analyzed, including European Standard EN1264：＂Floor Heating Systems And Components＂, 2000 A SHRA E Manual, ＂Warm water floor heating system design and construction manual＂ （Third Edition, in 2000）published by Japanese Floor Heating Industry Association, and the Chinese industry standord JGJ 142-2004, compong the pros and cons, degree of difftcuhy; Some sng gestions are proposed to provide peers the basis of choosing the heating mode.
