Therefore, the installation direction of the heat transfer member 4 can be changed as appropriate depending on the situation of the installation space in which the radiant panel 1 is installed.
  • Q(W) was determined from the heat absorption/radiation power (heat absorption/radiation power) due to the temperature difference T.
  • the density of water ⁇ is 1.00 ⁇ 106 (g/m 3 ) at 7°C, 9.90 ⁇ 105 (g/m 3 ) at 50°C, and the value of specific heat capacity ⁇ at constant pressure is 4.20 at 7°C. (J (K ⁇ g)) and 4.18 (J (K ⁇ g)) at 50°C, respectively
  • Q (W) is the temperature difference ⁇ T (°C) between the panel entrance and exit and the heat per minute. It was calculated from the flow rate L (l/min) of the medium using the formula defined below.
  • Q(W) ⁇ L ⁇ T/(1000 ⁇ 60)
  • FIG. 5 is a diagram showing the results of an experiment comparing the heating performance and cooling performance of the radiant panels of the example and the comparative example.
  • the cooling capacity increases as the flow rate of the heat medium increases, and furthermore, the flow rate of the heat medium in the example is 5 to 7. It can be seen that the improvement is about 20% in the range of 5 L/min, and about 25% in the range of the heat medium flow rate of 8.5 to 10 L/min.
  • the heating capacity increases as the flow rate of the heat medium increases in both Examples and Comparative Examples.
  • the difference between the example and the comparative example is even more remarkable compared to the cooling capacity, and when the flow rate of the heat medium is in the range of 5 to 7.5 L/min, it is improved by about 30%. It can be seen that when the flow rate is in the range of 8.5 to 10 L/min, the improvement is about 35%.
  • the performance of the example is improved in both the heating capacity and the cooling capacity, and the heat transfer member 4 according to the embodiment of the present invention has a remarkable improvement over the conventional structure. It can be confirmed that it is effective.
  • the heat transfer member and radiant panel according to the present invention can promote heat exchange with the outside through efficient radiation, and can improve comfort for users.
