摘要：

To effectively improve the heat storage performance of concrete radiant floor, a kind of concrete radiant floor with finned water supple pipes (Finned Concrete Radiant Floor) was designed. In the present paper, the heat storage performance of the new type concrete radiant floor was discussed based on experiments and a new simplified model. Experimental results showed that the average heat storage rate of the Finned Concrete Radiant Floor for start-up stage was about 88.7 W/m(2), 152.2 W/m(2) and 218.7 W/m(2) under the condition of water supply temperature 25.0 degrees C, 29.8 degrees C and 34.6 degrees C, which was about 2 times that of a non-Finned Concrete Radiant Floor. Calculation results showed that the average heat storage rate was relevant to both fin height and fin material, but irrelevant to fin thickness, and pipe spacing had a significant effect on the heat storage performance. This paper can provide a certain data basis for a better design of Finned Concrete Radiant Floor.
