The purpose of this study is to improve heat transfer rate and heat storage capacity by adding the heat sink in radiant floor heating system, which is widely used in residential building in Korea. In this study, a long-term measurement was accomplished to analyze the effect of the heat sink on indoor thermal environment and energy consumption of the radiant floor heating. The experiment was conducted by 7.5m × 4.6m test cell. Cell #1 represents a set up of conventional radiant floor heating system without heat sink, and Cell #2 represents a set up of the analyzed radiant floor heating system with heat sink. One side of the test cell is exposed to the outdoor and three side of the test cell is on the indoor. The experimental conditions were the same. Indoor set-point temperature was 24℃ and the test cell was heated by electric boiler.
As results of the long-term measurement, the total heating energy consumption was reduced about 11% when the heat sink was applied to the radiant floor heating system (Cell #2) compared to the conventional system (Cell #1). In addition, the indoor MRT(Mean Radiant Temperature) was ascended due to the uniformity of the floor surface temperature in Cell #2. This results in high OT(Operating Temperature) in Cell #2. The results show that the heating energy use can be reduced and indoor thermal comfort is improved by adding the heat sink in radiant floor heating system.
