We have developed a new room heating air conditioning system using phase change material having phase change temperature of 47℃ and 55℃. However, in the case of PCM of 47℃,40℃to 42℃ of water can be derived during heat discharging, and so it is unavoidable to operate both the heat storage tank and the heat pump, And in the case of PCM of 55℃, it is very difficult to use ordinary heat pump, because inlet water temperature of heat storage tank is necessary more than 65℃ for heat charging.
The purpose of thd development of PCM of 52℃ which consists of an acetic acid soda. And , after the completion of PCM, we investigated thermal performance of the latent heat storage tank of 2m3,which is fully filled with encapsulated PCM of 52℃.
As the results, it is possible to be charged by the water of 60-62℃because the heat pump is available. The discharging heat capacity until output water temperature 47℃ of the heat storage tank is almost equal to the existing heat storage tank using PCM of 47℃or 55℃.
