Study On Thermal Performance Of Prefabricated Thin Phase Change Heating Floor

A kind of prefabricated thin phase change heating floor was prepared by adding the shape-stabilized phase change material (PCM) into the prefabricated positioning plate, the thermal performance of phase change flooring at different average temperature of supply and return water was tested. The numerical simulation is carried out by using ANSYS software. The variation law and fitting relationship of surface temperature and heat flux with different average temperature of supply and return water were obtained. By comparing the experimental and simulated values, the error rate and the average correction factor were calculated.
