中文摘要: 建筑室内热、湿源位置和强度全年处于不断变化中,室内人员占据的局部空间和对温、湿度参数的需求也不断变化,由此构成室内源和需求的多变实际场景;传统空调的末端送风气流组织模式单一,难以高效应对负荷和需求随时间和空间的变化,导致较高的热环境营造能耗。申请者在本项目中将研究多种送风模式结合进行室内多变场景保障的多模通风策略研究,包括:(1)建立针对多变场景的需求描述方法;(2)建立基于需求的多模通风系统优化设计方法;(3)建立热、湿源位置与强度的辨识方法和针对局部温、湿度需求的送风参数优化方法;(4)建立基于源辨识和送风优化方法的多模通风模式切换和送风参数调节综合控制策略。通过本项目的研究,预期将建立高效应对多变场景的多模通风系统的设计和控制方法,为兼顾舒适性和节能的高效通风提供有效的解决方案,以期大幅降低室内空气环境营造的能耗。

英文摘要: In real operation of indoor environment, multiple scenarios exist, where both the scenarios of indoor heat and moisture sources in terms of location and intensity and the demand scenarios in terms of occupied location and required parameter change all around the year. Traditional airflow patterns are always a single system mode, which has a weak function in dealing with the changeable scenarios, resulting in a large energy consumption. In this research, multi-mode ventilation (MMV), a novel ventilation strategy is proposed to overcome the disadvantages of traditional airflow patterns. The research topics are as follows: (1) the definition method of the real demand scenarios; (2) the design method of MMV system; (3) the source identification methods for location and intensity of heat sources and moisture sources and the optimal method of supply air parameters oriented to local parameter demands; and (4) the overall control strategy of MMV. It is hoped that the reliable design and control methods can be proposed after the research and the indoor thermal environment can be maintained comfortable at a minimum energy consumption.
