Abstract
This paper describes evaluation results on energy consumption of Ice Thermal Storage Type Packaged Air Conditioners. Evaluation was performed using daily COP. The cycle using the same outdoor unit was examined and the conditions from which a thermal storage system becomes energy saving were clarified, and the simulation showed that it was energy saving. Moreover, it was shown that thermal storage system become energy saving, so that piping length between outdoor unit and indoor unit was long. It was also shown that the products of our company could cut down the CO_2 emissions.
