【摘要】：建筑能耗在我国总能耗中位列第三，约占到了1/3，空调系统能耗占建筑能耗的40%~60%。商业综合体建筑又是典型的高能耗建筑，目前该类型建筑在各一线城市甚至二三线城市的兴建活动又异常活跃，因此，为了使我国的建筑能耗早日达到发达国家的节能标准，商业综合体建筑的空调能耗的节能减排技术研究势在必行。本文以夏热冬冷地区商业综合体建筑为研究对象，重点研究空调系统的能耗，研究一些节能空调技术在该类型建筑中应用的节能效果。首先，按气候特征将夏热冬冷地区分为五个区域，每个区域选一个代表城市进行调查研究。每个区调查几个已建成的典型的商业综合体建筑，对建筑构成能耗、空调系统能耗情况、设备选型及使用效率、室内舒适度情况进行调查分析。其次，选择一个代表城市的商业综合体建筑，笔者选择武汉市的某商业综合体建筑进行能耗模拟，，模拟软件选择DeST，将模拟结果与实际情况进行对比分析，在此基础上将调查到的空调系统应用于该模型中，输出相关能耗数据，并进行有关分析；为了分析整个夏热冬冷地区的空调系统能耗，需将该模型应用于其他几个区的代表城市，并进行相同的模拟分析。再次，针对模拟的结果和调查数据，提出集中冷热源的思想，以减少设备初投资费用，提高设备的利用率，并针对这种技术提出可能出现的问题，寻找解决的方法。最后，寻找空调运行系统可以节能的技术，例如将水系统大温差运行、变风量空调系统、排风热回收技术、过渡季冷却塔免费供冷技术应用于商业综合体建筑中，通过模拟计算，对比调查中常用的空调系统能耗值，给出对比结果分析所选用的空调系统节能技术的可行性.
[Abstract]:Building energy consumption ranks third in the total energy consumption in China, accounting for about one third of the total energy consumption, and the energy consumption of air conditioning system accounts for 40% of the building energy consumption. Commercial complex buildings are also typical high-energy consuming buildings. At present, the construction activities of this type of buildings in first-tier cities and even second-third-tier cities are extremely active. Therefore, in order to make our country's building energy consumption meet the energy conservation standards of developed countries as soon as possible, It is imperative to study the energy saving and emission reduction technology of air conditioning in commercial complex buildings. This paper takes commercial complex buildings in hot summer and cold winter area as the research object, and focuses on the energy consumption of air conditioning system. The energy-saving effect of some energy-saving air-conditioning technology applied in this type of building is studied. First of all, the hot summer and cold winter regions are divided into five regions according to the climatic characteristics. Each region selects a representative city for investigation and study. Each district investigates several typical commercial complex buildings that have been built, which constitute energy consumption for the buildings. Air-conditioning system energy consumption, equipment selection and use efficiency, indoor comfort is investigated and analyzed. Secondly, the author chooses a commercial complex building which represents the city. The author chooses a commercial complex building in Wuhan to simulate energy consumption, and the simulation software chooses set. The simulation results are compared with the actual situation. On this basis, the investigated air conditioning system is applied to the model, the relevant energy consumption data are outputted and analyzed, in order to analyze the energy consumption of the air conditioning system in the whole hot summer and cold winter area, The model needs to be applied to representative cities of other districts and the same simulation analysis is carried out. Thirdly, according to the results of simulation and investigation data, the idea of concentrating heat and cold source is put forward to reduce the initial investment cost of equipment and improve the utilization rate of equipment. Finally, looking for technologies that can save energy in air conditioning systems, such as large temperature difference operation of water systems, variable air volume air conditioning systems, exhaust heat recovery technology, free cooling technology for cooling towers in the transitional season, and application in commercial complex buildings. Through simulation and calculation, the energy consumption of air conditioning system commonly used in investigation is compared, and the feasibility of the energy saving technology of air conditioning system selected for comparison analysis is given.
