The Energy Efficiency Designing And Optimal Management Of Large-scale Public Buildings Air-conditioning System

With the development of city construction, energy consumption has increased year after year. The proportion of energy consumption in total social energy consumption has increased in the term of a large quantity of large-scale public buildings especially. The work in the energy saving of large-scale public buildings started so late that a mass of energy waste in the operation and management of air-conditioning system. Therefore, it's necessary to analyze the energy saving of large-scale public buildings, to research technology of energy saving in air-conditioning system and the operation and management.In this paper, large-scale public buildings, the common public buildings and the other civil buildings have been introduced. From the statistics, the pessimistic condition of energy consumption of large-scale public buildings has been educed. It's still significant to go into on analyzing the energy saving of large-scale public buildings, researching technology of energy saving in air-conditioning system and the operation and management. It has been introduced theoretically that calculation methods of buildings load to hold out decreasing the energy consumption. It has been compared that the effect on buildings load using different materials of building envelope(exterior wall, window) by using HAP(Hourly Analysis Program). In addition to, the effect of the air-conditioning system with heat recovery or VAV system has been analyzed quantitatively. The particular introduce of HAP can assist on the development of similar software.In this paper, the application of technology of energy saving in air-conditioning system, especially, about the large-scale public buildings have been discussed. By means of the introduce of some technology of energy saving such as cool storage air conditioning technology, we have draw out major potential of energy saving for large-scale public buildings.Question for the optimal management of large-scale public buildings, building intelligent, energy management contract, intelligent management mode have been placed great emphasis on. And the last, the effect of personnel, policies and regulations, supervision could not also been ignored.
