Abstract
We proposed a thermoacoustic cooling system as a technique using solar heat energy. My previous study confirmed that this system can drive and cool materials using solar heat energy. The amount of solar heat energy depends on the season because solar heat energy is natural energy. Therefore, examination of whether a long-term drive of this system is possible irrespective of the season is necessary for practical use of thermoacoustic cooling systems using solar heat energy. This report descries a driving experiment of the system operating between April and December. Results demonstrate the possibility of long-term driving of the thermoacoustic cooling system using solar heat energy by shortening the time until reaching this system's oscillation temperature.
