Résumé

For effective use of excess exhaust heat from gas engines, a novel PCM was prepared by adding anhydrous sodium sulfate and D-mannitol to ammonia alum hydrate. It melted and stored latent heat at the temperature range of exhaust heat from gas engines (around 90°C). Heat storage and release characteristics of the novel PCM were investigated with a heat storage tank containing hot water and the novel PCM packaged into resin bags. As a result, the novel PCM stored and released more than 400 MJ×m-3 of heat at the temperature range between 80°C and 90°C. The amount of heat storage and release by the PCM was approximately ten times higher than that of water with same volume. This result indicates that the novel PCM can reduce the volume of hot water tank dramatically in addition to storing and releasing exhaust heat from gas engines.
