Energy Consumption and Analysis of Air-Conditioning System of Large-Scale Public Buildings in Xi'an

As the main consumption equipment, the air-conditioning system of large-sized public buildings in Xi'an consumes 30%~¬60% of the total energy. Combining with the survey data and related norms, the paper analyses the energy consumption from the following aspects: basic situation of building, index of building energy consumption, ratio of energy consumption of air-conditioning system, load of air-conditioning and indoor environment. Thus, it will give a rational and scientific understanding to energy-efficiency of air-conditioning system of large-scale public buildings in Xi'an for the purpose of providing an efficient assistance to improving the energy consumption of air-conditioning system.
