| Abstract |
This study is to derive the melting temperature range for applying phase change materials to buildings, and propose climate zones for each
administrative region in Korea based on outdoor weather data variables affecting the melting temperature range of PCM, and analyze
simulations. Through this, the melting temperature range of the PCM module attached to the building envelope was derived, and the results
are as follows. (1) Factors influencing the melting temperature of PCM are surveyed by Heat Degree Hours, Cool Degree Hours, and solar
insolation amount, and 14 climate zones were classified by selecting the ASHRAE classification method. (2) PCM increases heating energy
consumption, but as cooling energy consumption decreases significantly, total energy consumption decreases. It is analyzed that the energy
saving rate is reduced by 0.87 ~ 2.4%. (3) The proper melting temperature of PCM is a valid result, because it is analyzed that the phase
change temperature is different according to the proposed climate zone. It is judged that classification by climate zone will be effective when
constructing PCM design data for building applications. |
