The ice thermal storage system has influence on energy consumption, especially the amount of one. In order to survey this effect, the amount of energy consumption was measured concerning two systems, the ice thermal storage system and the conventional one, in office building. As a result, the ice thermal storage system consumed 55% more energy in comparison with the conventional one. It is caused by the lower COP of the ice thermal storage system which drives under the condition of lower evaporating temperature than the conventional one. Through this actual survey, it became clear that the ice thermal storage system was not effective to energy conservation.
