摘要：
The multi-factor orthogonal simulation analysis was initiated to investigate the influence degree of four key parameters of PCM-integrated building envelopes on energy consumption and indoor thermal comfort under Chinese climate. The sensitivity and the interaction between four key parameters on energy saving and indoor temperature were discussed. The results showed that: 1) According to the influence degree on energy consumption and indoor thermal comfort time, the four key parameters of PCM envelope can be ranked in descending order as follows: envelope type > PCM layer layout > PCM type > PCM layer thickness. 2) The optimal level of all the cases studied is using BioPCMTM23 (PCM2) with a thickness of 7 cm on the inner side of both wall and roof. 3) Integrating the PCM to the envelope can effectively reduce the indoor temperature fluctuation. Considerable energy saving effects (the energy saving rate is 4.8% - 34.8%) can be achieved by properly selecting the PCMs according to local climatic conditions. The PCMs with high latent heat should be selected and placed in an envelope structure that receives longtime solar radiation and has a large surface area, which can maximize the effect of energy saving and temperature control.
