公共建筑过渡季通风需求与空调通风系统对策分析
Analysis on ventilation demand and air conditioning ventilation system of public buildings in transition season
摘要：
基于实际工程项目的设计资料调研和计算分析，对比分析了空调新风量与过渡季通风量的差异，发现现有公共建筑普遍存在过渡季全新风通风换气量不足的问题，难以满足消除室内余热的需求。研究表明：对于公共建筑中的半集中式空调系统，现有系统设计难以满足过渡季全新风运行；对于集中式空调系统，选择合适的过渡季室内设计温度和风机策略，现有系统设计可满足过渡季全新风运行。
Abstract：
Based on the design data investigation and calculation analysis of the actual project, compares and analyses the difference between the outdoor air volume of air conditioning system and the ventilation volume in transition season, and finds that the existing public buildings generally have the problem of insufficient outdoor air ventilation in transition season, which is difficult to eliminate the indoor residual heat. The research results show that: for the semi-centralized air conditioning system in public buildings, the current system is difficult to meet the demand of all-outdoor-air operation in transition season; for the centralized air conditioning system, under the consideration of selecting appropriate indoor design temperature and fan strategy, the existing system can meet the demand of all-outdoor-air operation in transition season.
