【摘要】：空调技术的诞生和发展在为人类自主创造舒适的建筑环境提供极大便利的同时,也带来了诸如建筑能耗大幅增加、室内空气品质恶化、病态建筑等亟待解决的问题。混合冷却(Mixed-Mode Cooling)是在夏季的不同气候条件下,通过采用不同的冷却方式来满足建筑室内人员的热舒适,同时降低建筑能耗和空调运行费用的一种冷却方式。本文以理论计算与数值模拟相结合的方法对具有典型夏热冬冷地区气候特征的株洲地区的办公建筑的混合冷却运行策略进行了研究,以期为混合冷却技术在建筑节能领域中的应用提供借鉴。本文首先回顾了国内外对混合冷却的研究现状,在分析和总结前人研究成果的基础上得出,达到混合冷却预期目标的关键在于有效的运行策略,即建筑冷却模式的切换。本文从以下三个方面对夏热冬冷地区办公建筑的混合冷却运行策略展开研究。作为一种低能耗的冷却方式,通风冷却方式将直接影响着建筑能耗的高低,研究首先从通风冷却的基础理论入手,详细介绍了不同通风模式的作用原理,经典的通风研究模型、方法及结论、通风的功能、热舒适理论和建筑热平衡理论,以此为后续的理论分析提供理论基础。基于非采暖空调环境下的热舒适适应性标准、室内空气品质的需求和建筑热平衡理论,确定了同时满足热舒适和室内空气品质的需求通风量为混合冷却运行参数。以株洲地区典型办公建筑为例,在分析当地典型气象年数据的基础上,确定了热舒适温度范围,建立了混合冷却运行策略。通过建立建筑模型和相关的理论计算,在理论上分析了混合冷却运行策略的有效性。最后采用De ST软件对建筑模型进行了建筑热过程模拟,分别对运行策略的热舒适满足率和节能潜力进行了模拟分析,以此来对本文提出的混合冷却运行策略的应用效果加以验证。本文采用了理论计算与数值模拟相结合的方法对夏热冬冷地区办公建筑混合冷却运行策略进行了研究分析,可为混合冷却技术在建筑节能领域中的应用提供借鉴。
[Abstract]:The birth and development of air conditioning technology not only provides great convenience for people to create comfortable building environment, but also brings great increase in building energy consumption and deterioration of indoor air quality. Mixed cooling (Mixed-Mode Cooling) is to meet the thermal comfort of indoor personnel by adopting different cooling methods under different climate conditions in summer. A cooling method to reduce building energy consumption and air conditioning operation cost at the same time. In this paper, the mixed cooling of office buildings in Zhuzhou area with typical climate characteristics in hot summer and cold winter area is combined with theoretical calculation and numerical simulation. But the running strategy is studied, In order to provide a reference for the application of hybrid cooling technology in the field of building energy conservation, this paper first reviews the current research situation of mixed cooling at home and abroad, based on the analysis and summary of previous research results, The key to achieving the desired goal of mixed cooling is an effective operational strategy. In this paper, the mixed cooling operation strategy of office buildings in hot summer and cold winter area is studied from the following three aspects. As a low energy consumption cooling mode, this paper studies the mixed cooling operation strategy of office buildings in hot summer and cold winter area. The ventilation cooling mode will directly affect the building energy consumption. Firstly, starting with the basic theory of ventilation cooling, this paper introduces in detail the action principle of different ventilation modes, classical ventilation research models, methods and conclusions, and ventilation functions. The thermal comfort theory and the building thermal balance theory provide the theoretical basis for the subsequent theoretical analysis. Based on the standard of thermal comfort adaptability under non-heating and air-conditioning environment, the requirement of indoor air quality and the theory of building heat balance, The requirements of both thermal comfort and indoor air quality are determined as mixed cooling operation parameters. Taking the typical office buildings in Zhuzhou area as an example, the range of thermal comfort temperature is determined on the basis of analyzing the local typical meteorological data. The mixed cooling operation strategy is established. The effectiveness of the hybrid cooling operation strategy is theoretically analyzed by building model and related theoretical calculation. Finally, the thermal process of the building model is simulated by using de St software. The thermal comfort satisfaction rate and energy saving potential of the operation strategy are simulated and analyzed respectively. In order to verify the application effect of the hybrid cooling operation strategy proposed in this paper, the mixed cooling operation strategy of office buildings in hot summer and cold winter area is studied and analyzed by the combination of theoretical calculation and numerical simulation. It can provide reference for the application of hybrid cooling technology in the field of building energy conservation.
