Research On Ice-storage Air Conditioning System In Technology

This paper analyses the design of ice-storage air conditioning system for the civil architecture. With a fast economic growing, the city electric power system is facing with a severe test because air conditioning systems in new or reformed buildings become more, the working time of air conditioning systems are increasing and the city electric power system is tending to ageing. The electric consumption of air conditioning system is primary in a building, which account for 1/3 of the electric consumption of the whole building. The ice-storage air conditioning system has a function of cutting the peak and filling the valley of electric consumption that is good for operating of city electric network. This paper points out that a precise heating and cooling load hour-by-hour calculation should be done for the design of the ice-storage air conditioning system. It is the basement for optimum design, select and control of air conditioning systems. The precise load is quite difficult to calculate because of all sorts of factors in many air-conditioning system design at present so that the capacity of air-conditioning system is often larger than the actual demand, which causes that the space for the air conditioning machines take up excessive floor and the electric distribution equipments for air-conditioning system has increased. The system will not achieve the optimum control on the investment, the energy consumption, the operating cost, the floor space and so on.Combining with a practical project that is a civil building in Chengdu, this paper presents the calculation and analyses of the ice storage air-conditioning system. Based on summarizing the previous researches and experiences, this paper discusses some new viewpoints and methods, which will promote the application and development of the ice storage air-conditioning system. As a result, the pressure of electric power and electrical network will be alleviated and a unity of the benefits on the economy, the society and the environment will be achieved.
