| Abstract: | Based on the experiments done in Beijing, the model of radiant floor heating system was modified with form-stable PCM as the thermal mass set up before. The thermal performance of the system was simulated by using the modified model. The calculated results agree well with those of the experiments. Then the model was used to investigate the influence of the melting point, the phase change latent heat, the phase change radius and the heating power of the form-stable PCM on the performance of the system. |
