Based on the local meteorological conditions,the relationship of efficiency of ice storeage in winter utilizing conical ice between ice storeage and radius of conical ice.

The influences to initial investment,operating expenditure,as well as overall annual cost of the ice storage air conditioning system by such factors as cool storage rate,peak-and-valley electrical price pattern and types of ice storage system are analyzed.

Impact of ice storage rate on the system economic effects and determination of its optimum;

Based on the traditional methods of economic analysis for cool storage system, the paper takes into account the initial investment, operation cost of additional equipment and the management cost of system, analyses the impacts of storage rate upon economical performance combined with a typical project example.

Then,the equivalent day in the design ice-storage rate of the ice-storage air conditioning system is calculated.
