It not only efficiently makes use of the various low energy to the energy efficiency, but also has the even room temperature 、good sanitation、good fort and so on. So it is a ideal heating system that reduces the consumption of energy and raises the thermal fort. At present the low temperature water floor heating has been used widely overseas, but in my country it is still at starting stage of the unmature acknowledgement for the thermodynamic performance. The design、practice and operation technology are not perfect.This paper is a system design of the low temperature water floor panel heating system for the housing building. The floor heating system is a kind of system ensuring good fort and energy efficiency in parison with the others.First, this paper analyzes the present conditions, evolution, advantages, disadvantages, the features in heat transfer and tubing. Second, it calculates the heat load of the housing building. Perceived room temperature exceeds the designed temperature of floor panel heating, so the floor heating has the differences in indoor thermal fort from that of other heating modes on the basis of thermal fort theories. Through a quantitative analysis of overall energy efficiencies, this design adequately reduces the indoor heating temperature of the heat load calculation while keeping the same heating effect. In aspect of the laying tubing, this paper adopts the double spiral of concrete embedded plastic radiant floor heating. The method can achieve a even floor surface temperature. Last, the heat meter and thermostatic radiator valve setting in the every house control the temperature and implement the house hold heat metering. All of the above, the low temperature water radiant floor heating is a ancient efficient heating method.Key words: floor heating system。主要是以不高于60℃的低溫?zé)崴疄闊崦簩⒓訜峁苈裨O(shè)在地板中，以整個(gè)地面為散熱面。在很久以前中國人就發(fā)明了火炕，而且一直延續(xù)至今。60年代由于采用了高溫水而引起腿部不適，影響其發(fā)展。日本在近50年代重新認(rèn)識(shí)了這一傳統(tǒng)的采暖技術(shù)，開始發(fā)展熱水式地板采暖裝置。以上各國到目前為止，低溫地板輻射采暖使用已較廣泛，而在我國由于對(duì)該系統(tǒng)的熱工性
