[0050] Reference Figure 9The measuring points at each location are arranged as follows: temperature sensors 24 and heat flux density sensors 25 are arranged sequentially at the four-quarter points of the two diagonals inside the chamber. Then, heat flux density sensors 25 are arranged at the four-quarter points of the vertical and horizontal directions passing through the center point. There are four temperature sensors 24 and five heat flux density sensors 25 in each layer. The measuring points at each location on the bottom plate assembly are arranged as follows: temperature sensors 24 are arranged at approximately the four-quarter points of the two diagonals of the bottom plate assembly. Then, the temperature sensor measuring points in the air gap are in the same positions as the measuring points on the upper surface of the bottom plate. There are five temperature sensors in each layer. Then, five temperature measurement points are set at 0.1m, 0.6m, 1.1m, 1.6m, and 2.1m in the vertical direction. Thermally conductive silicone is evenly applied to the surface of the heat flux density sensor 25 and then placed at the predetermined measurement point position. The temperature sensor 24 is directly fixed at the predetermined measurement point position with tape. The temperature sensor 24 placed in the air gap needs to be drilled on the surface of the base plate assembly according to the predetermined measurement point position. After the temperature sensor 24 is placed in the hole, it needs to be sealed with structural adhesive.
[0051] Reference Figure 10 Water inlet 33 and water outlet 34 are opened on the left side of the box to house the water inlet pipe and the water return pipe. The box is then sealed with structural adhesive to prevent air from entering and affecting the accuracy of the experiment. The water pipes can be laid in various ways, such as folded type, parallel type, double parallel type and cross double parallel type.
[0052] Reference Figure 10 A floor module 35 is installed on the base plate assembly. The top surface of the floor module 35 has a pre-embedded groove for laying pipes. The floor module is fixed to the base plate assembly with cement mortar 36 to prevent the floor module 35 from moving when laying water pipes. The water pipes are laid along the pre-embedded groove of the floor module 35. If the water pipes cannot be fixed, they need to be fixed again with fasteners. After the water pipes are fixed, cement mortar 36 is applied to the floor module 35, and then the gaps are sealed with structural adhesive to prevent air from entering and causing errors in the experimental data.
[0053] The data acquisition unit 20 obtains the values from the temperature sensor 24 and the heat flux density sensor 25. If any abnormalities occur, the location of the sensors can be quickly determined for rapid problem resolution. The test data from the data acquisition unit 20 allows for the optimization and improvement of the floor radiant heating system, enhancing its efficiency and comfort.
