The high efficient co-generation system named "Neighboring Communities Co-generation System" is proposed to a multiple dwelling house. The key technology of this system is to connect home and home with one loop of heat transfer line of one inch diameter, and to level the heat demand by a heat storage unit in each house. This system require compact and high response heat storage unit. In this study, a plate fin type brazing heat exchanger was applied and tested for a heat storage unit. Sodium acetate trihydrate with a melting point of about 58 ^ΩC and paraffin wax with a higher value of 74.8 ^ΩC were used as the phase change material (PCM). As a result, it was shown that the heat transfer in the heat storage unit was dominated by thermal conductivity in PCM. Paraffin wax made higher responsibility and higher heat output due its higher melting point and quite small super cooling in solidification.
