Study Of Energy Conservation In Large-typed Emporium Buildings

With the economic development and improvement of people, living conditions, highgrade emporium buildings are emerging rapidly all over China and energy consumption of the air-conditioning system is increasing greatly. The energy consumption of HVAC system has become the main part of the building energy consumption. So how to develop the energy saving designing work has become an urgent project to be solved. However, due to lack of the deep research of the design and the operation of the emporiums, HVAC systems and a method to analyze the energy saving effect of the HVAC systems, the energy saving designing work has not be developed widely and deeply. So the energy consumption of the HVAC systems is still very high.This thesis means to solve the above two problems existing in the energy saving designing work. Firstly, some emporiums are investigated and the problems of the design and the operation are summarized. Then the energy saving evaluating method of the emporiums buildings is deeply studied and the theory and the data basis of energy saving evaluatingwork are proposed.This thesis proposes a new method to estimate the energy consumption of emporiums building, such as ventilation system of HVAC and water system of HVAC, which will be very helpful for energy conservation work of emporiums buildings and other types of buildings.In addition, the concrete process of the energy saving designing works are analyzed and the energy conservation estimating results have been proposed, so the method of energy conservation evaluating work can be stated more clearly.
