Abstract
In Japan, effective utilization of waste heat from power and production plants has become very important to restrain output of CO_2. But it is difficult to use waste heat on site or very near by. Because waste heat from power and production plants is too many value to use for heating and cooling applications on site. We need the method to transport waste heat to heating and cooling applications of other site. Kobe Steel Ltd. is developing latent thermal energy storage equipment for this transport system. This equipment used Erythritol of phase change material (PCM) and direct contact heat transfer technology. Direct contact heat transfer technology is heat exchange method contacted heat medium to PCM. The advantage is high performances of heat input and heat output, light weight equipment by no heat exchanger. In this time, the authors estimated the performances of heat input and heat output by experimental equipment including Erythritol of 15kg. As the result, the authors succeeded high performances of thermal energy storage and stable running by this equipment. We show the performances of these systems for latent thermal energy storage.
