摘　　要：本文建立了采暖系统的分析模型 ,利用所建立的模型 ,对地板辐射采暖和传统的散热器采暖两种采暖方式进行了分析。结果表明 ,当地板辐射采暖的供回水温度为 4 5℃ 35℃时 ,与传统的散热器采暖相比 ,其效率大约高 18% ,地板辐射采暖所需供水温度低 ,可以充分利用各种低温热源及工业废热等低品位能量 。A physical model of exergy analysis of heating system is presented in the paper,and the low temperature radiant floor heating system is compared with radiator heating system based on the model.When the temperature of water supply and retun in the system are 45℃/35℃ respectively,the exergy efficiency of the radiant floor heating system is 18% higher than that of convertional radiator heating system,and the industrial waste heat can be effectively utilized in the radiant floor heating since the temperature of water supply required in the system is low,it is a promising and energy-saing heating system.
