被动式建筑具有密闭性良好、减少能量损失的优势,在我国农村地区应用具有重要的节能意义。由于围护结构密闭性较高,被动式农村住宅通风换气技术对提高和保障室内空气品质和环境热舒适性尤为重要。针对沈阳某高校示范建筑,分析通风换气技术对其室内环境热舒适性影响,应用Airpak软件进行数值解算,给出室内温度场、速度场和PMV、PPD指标的分布状况。分析不同送风温度、送风风速工况条件下的室内空气温度分布情况,以及PMV、PPD指标对室内环境热舒适性的影响,确定满足环境热舒适性要求的送风工况,为农村被动式住宅的通风换气技术应用提供基础依据。
Passive buildings with airtight good, reducing the energy loss advantages, the application in rural areas of our country has an important energy-saving significance. Due to the high confinement of the enclosure structure, passive residential ventilation technology is particularly important to improve and ensure the indoor air quality and environmental thermal comfort. Aiming at the demonstration buildings in a university in Shenyang, the influence of ventilation technology on the thermal comfort of indoor environment was analyzed. Airpak software was used to solve the problem. The distribution of indoor temperature field, velocity field, PMV and PPD was given. Analyzed the temperature distribution of indoor air under different supply air temperature and supply air speed, as well as the influence of PMV and PPD on the thermal comfort of indoor environment, and determined the supply air condition to meet the requirements of environmental thermal comfort. Residential ventilation technology to provide the basis for the application.
