In this study, a temporary space cooling system using ice was evaluated for the simple cooling of spaces, such as prefabricated buildings and tents used for events and at times of disaster, and analysis and experiments were conducted concerning the system. First, the concept of this system was established. Two types of cooling methods - natural and forced circulation - were adopted. Next, the cooling capacity was predicted by calculation. Measurement results were also presented concerning the cooling capacity of the forced circulation-type system in a temporary tent. Furthermore, this system was actually tested on a temporary tent and a prefabricated building and demonstration experiments were conducted. The operation results were indicated and the cooling capacity was evaluated.
