With economic growing and the improvement of people’s living quality in China,modern architecture is increasing rapidly, central air-conditioning system has been widely used. The Public building contains which contains Handle official business building , business building,tour building and so on. Due to the set of central air conditioning systems, large-scale public building energy consumption is quite high. As a major energy-consuming devices in large public buildings, Air conditioning systems due to problems in the design and operation, there are many unreasonable phenomenon,50%~60 of the total consumption of building energy consumption, to the great pressure on urban power network operation, Assistant Officer for energy-saving alteration and optimization。Consumption in Market Building specially the air conditioning energy consumption, and understand the chiller’soperation parameters, thus for the optimal control, improving operation management and reducing the running cost of the central air conditioning system. From the air conditioning load and air conditioning systems, air conditioning and other aspects, grasp the characteristics of air conditioning systems of large commercial building, behind the energy-saving optimization provides a solid basis.After central air conditioning systems design, construction and put into operation, Many factors affect its energy consumption level in the run management level are extremely important factors. First Tian He City of Guangzhou as a typical representative, through field research, to get started with basic profiles of large commercial buildings.Secondly, based on the thermodynamics, This article by Tian He City Central air conditioning system running data for 2010 June-August, a comprehensive analysis of air conditioning units running conditions, came to load changes, energy consumption of air conditioning system. Analysis of key problems in air conditioning energy consumption, combined with the above optimization strategies, identify energy-saving measures while the system is running, with a view to achieve the goal of energy conservation.Through this project research, may be well known the structure of energy , master the operating characteristics of centrifugal chillers, so as to optimize central air conditioner running, improving central air conditioning system operation management, reducing central air-conditioning running costs provide a useful reference.
