| 中文摘要 | With the development of social economy, the electricity difference between on-peak hours and off-peak hours is becoming larger. Air-conditioning system is the main reason that makes the electricity load imbalanced. As one of the successful strategies of demand side management of electricity, thermal storage air conditioning system is becoming more and more popular in the world. It is a powerful technology of shifting electricity load from on-peak hours to off-peak hours. Direct evaporation internal-melt thermal storage air conditioning system is one kind of thermal storage systems. It has been developed recently. It is suitable for home or commercial building air conditioning system. The operation of direct evaporation thermal storage system is much related to complicated heat transfer process with solid-liquid phase change. The dynamic characteristics and heat transfer characteristics are important to the design and optimization of the system. Meanwhile, since the thermal storage tank is added to the general air conditioning system, the analysis on the coupling relations among main parts and the heat transfer characteristics of the whole system is necessary. The paper mainly focused on the following aspects, 1) experiments of the ice charging process, discharging process and the heat charging process with the sample system; 2) numerical simulation of direct evaporation thermal storage air conditioning system. First, a series of experiments were carried out during the ice charging process, discharging process and heat charging process with the sample system of direct evaporation of thermal storage air conditioning system. Then the paper analyzed the heat transfer characteristics of the thermal storage tank, developed the mathematical model basing on the heat transfer and energy conservation. The heat transfer coefficient and its dynamic characteristics during the charging and discharging process were numerically analyzed. Basing on the analysis of thermal storage tank and the general air conditioning system, from the perspective of system operation, the mathematical model for the whole direct evaporation thermal storage air conditioning system was founded. With the coupling relations among different main parts, the system’s heat transfer characteristics and dynamic characteristics were studied. |
