中文摘要	With the development of social economy, the electricity consumption by air conditioning increases unceasingly. Even the electricity peak due to the air conditioning is often at the same time with the industry trade peak, which worsen creates the peak electric power resources shortage, and the electricity difference between on-peak hours and off-peak hours is becoming larger. The ice-storage air conditioning system, as a powerful technology of balancing electric loads from on-peak hours, has the great significance to the electric network. The dynamic ice cold storage technique is the important research direction of the ice storage air conditioning system, In order to obtain guidelines for engineering applications, experiments were conducted using the dynamic ice cold storage air conditioning system developed by Guangzhou Institute of Energy Conversion ,and the paper mainly focused on the following aspects; 1) The influences of different initial cool thermal storage rate, different cooling load of end-users, different discharge water flow rate and different ice-melting velocity on the discharging characteristics were analyzed in detail, the results show that the ice-melting velocity plays an important role in discharging characteristics, and initial cool thermal storage rate, discharge water flow rate and cooling load of end-users have little effect on the discharging characteristics. 2) In order to get the optimum pipeline designs in ice storage tank during the ice charging process, several ice-melting experiments were conducted. The results show that there exists an optimum pipeline arrangement in the discharging process considering ice discharging efficiency, and the output water of the ice storage tank has little effect on the velocity of ice-melting. 3) The influence on the discharging efficiency of the velocity field in the ice storage tank produced by the input water and output water was analyzed. Through this experimental study, the crucial discharging parameters of the dynamic ice storage air conditioning system were obtained; at the same time, an optimum pipeline design in the ice storage tank during ice discharging process was also obtained. And the experimental foundation and the design instruction were to be provided for the product development of the dynamic ice storage air conditioning.
