Abstract
The objectives of this study involve evaluation of the thermal behaviors of shape-stabilization phase change material (SSPCM) manufacturing machines and SSPCM radiant floor heating (RFH) systems to determine their effectiveness in reducing building energy consumption. SSPCM manufacturing machine can produce more than 1500 g of SSPCM at a time. The advantages of this form of manufacturing include a 3-step filtered method and a two-step simple process. The mixing ratio for RFH was cement: sand: water at weight ratios of 1: 3: 0.5. Measurement results reveal that the thermal conductivity of SSPCM A_10 and A_20 increased by 107.2% and 115.84%, respectively. In thermal room analysis, A_80 case shows a heat maintenance effect of 42 min compared to A_10. Furthermore, the peak temperature is 0.4 °C higher in A_80. Additionally, more specific analysis reveals that the heat flow data presents a small input quantity of SSPCM stored thermal energy as latent heat storage (LHS). Therefore, the thermal performance of SSPCMs produced by the machine is sufficiently confirmed through experiments applied to RFH.
