The Study On Comprehensive Energy Consumption Of Cold And Heat Sources In Large Office Building In Xi'an

With the serious situation of the growing international energy issues and the increase of the large office buildings, the energy consumption problems of large building' air-condition become more and more important. At present in large office building air-condition system, cold and heat source design and operation management, there still exists insufficiency from the view of the use of energy and energy consumption. How to choose the cold and heat source in air-conditioning systems reasonably has been a focus to designers and construction owners. Based in Xi'an's construction of energy sources, the thesis raises a number of different kinds of cold and heat source through the application of energy to improved BIN method with the Xi'an large office building for the load of the building simulation. And to apply a different source of cold and heat air-condition programmer to calculate the air-condition buildings energy consumption. Based on the Xi'an current energy prices and every-year operating expenses, the thesis draws the operating expenses that air-condition buildings spend on the different cold and heat source every year through the methods of every-year operating expenses. Combining energy consumption and every-year operating expenses in the calculation, the results can be obtained: The changes of building air-condition energy consumption and operating costs are the in-synchronisms in characteristics; in the scattered wet and a large quantity of large office buildings in Xi'an, the choice of ice storage air-condition and heat source approach is more reasonable.
