夏热冬冷地区居住建筑混合通风系统分析
Hybrid ventilation system of residential buildings in hot-summer and cold-winter zone
摘要：
通过对非供暖空调环境下人体热适应性的分析，确定体感温度为混合通风系统的调控目标参数。分析了夏热冬冷地区非人工冷热源热湿环境体感温度范围和评价等级，得出夏热冬冷地区不同室外空气温度下满足室内热舒适条件的混合通风量范围。采用实测和软件预测2种方式，对居住建筑混合通风量和自然通风量分别进行了定量分析。通过对需求通风量与自然通风量的对比，得出满足室内热舒适所需的机械通风量，确定了非供暖空调环境下混合通风系统的控制流程。
Abstract：
Analyses the human body’s thermal adaptability in the natural environment, determines the sendible temperature as the control target parameter for hybrid ventilation system. Analyses the sendible temperature range and evaluation level in the natural environment in hot-summer and cold-winter zone, and confirms the air flow range of hybrid ventilation which meets the indoor thermal comfort condition at the different outdoor temperatures. Quantitatively analyses the hybrid ventilation rate and natural ventilation rate of residential buildings by measuring and software prediction. Obtains the satisfied mechanical ventilation rate by comparing the demand ventilation rate with the natural ventilation rate. Determines the control process of hybrid ventilation system under the condition of natural environment.
