Abstract: Economic analysis of ice storage air conditioning system for an office building. Then capered the hourly electricity charge between the ice-storage air-conditioning system and conventional air conditioning system based in different cooling loads. Though the charts, we will know the economy of the ice-storage air-conditioning system more perceivable. In the end, the feasibility of the air conditioning project is proved above the calculation of the payback period.

Key words: ice-storage air-conditioning system, economic analysis, ice storage proportion, payback period, office building
