摘要:
为确定热舒适需求与空调节能设计过程中的关键能量设计要素之间的关联性,提出了一种基于热舒适的空调能量设计因子提取及其重要度计算方法。在热舒适空调节能设计过程框架的基础上,建立了基于热舒适需求的功能质量屋,并将热舒适性转化为空调功能及权重等设计信息;分析功能的能量特性,针对与能耗相关的功能,给出了能量设计因子提取策略,以及能量设计因子对热舒适及能耗综合影响程度量化方法。以家用空调为例,提取了基于热舒适的能量设计因子,对容积效率和传热系数两项耦合因子进行了分解,并对整体层能量设计因子的热舒适性及能耗的影响系数进行计算,按综合影响系数由大到小排序,结果为压缩机功率、系统控制方式、通风量和换热量。

Abstract:
In order to determining the relevance between thermal comfort and key energy design elements during energy-saving design process, the method of extracting energy design factors of air conditioning and calculating its weight is proposed. The house of quality based on thermal comfort is built with the energy-saving design frame. The thermal comfort requirements are converted to function and weight of air conditioning. The energy characteristic of the function is analyzed, and the extract means of energy design factors is provided based on the relation of functions with energy. The method of calculating influence degree of energy design factors on thermal comfort and energy consumption is also put forward. Taking the household air conditioning as a case study, the energy design factors based on thermal comfort are extracted. Two coupled factors, volume efficiency and heat transfer coefficient, are decoupled, and the influence coefficient of energy design factors on thermal comfort and energy consumption in overall layer are calculated. The comprehensive influence coefficient in descending order is compressor power, system control mode, ventilation quality and heat exchange amount.
Key words:  household air conditioning  energy design factors  thermal comfort  energy-saving design
