摘要:

阐述了“通风优先,热湿调控配合”的居住建筑空气与热湿环境调控设计总体思路。在分析夏热冬冷地区城市气候资源,明确建筑所在城市暖通空调季节划分、住户人员结构和住宅使用模式的基础上,指出营造健康舒适的室内环境需要将室内相对湿度作为热湿环境控制的设计指标,根据住宅各功能房间的使用模式分别设定房间使用时段和非使用时段的室内热环境参数,依次进行各房间的负荷计算分析和冷热源设备选型,实现节能的目的。针对夏热冬冷地区居住建筑空气与热湿调控需要,给出了相关的通风、供暖和空调设计技术要点和措施。

Abstract:

Expounds the general idea of air quality and thermal and humidity environment control design of residential buildings with “ventilation priority, thermal and humidity matching”. Based on the analysis of urban climate resources in hot summer and cold winter zone, and the clarification of the HVAC seasonal division in the city where the building is located, the personnel structure of residents and the residential use mode, points out that in order to create a healthy and comfortable indoor environment, the indoor relative humidity should be considered as the design index of thermal and humidity environment control. According to the use mode of each functional room, the indoor thermal environment parameters of the room in use period and non-use period should be set respectively for the load calculation and analysis of each room and the selection of cold and heat source equipment to achieve the purpose of energy saving. In response to the air quality and thermal and humidity environment control needs of residential buildings, gives the specific technical points and measures for ventilation, heating and air conditioning design.
