双温冷源温度湿度独立控制空调系统新风系统设计探讨
Outdoor air system design in the temperature and humidity independent processed air conditioning system based on double temperature cold sources
摘要：
以北京市某工程双温冷源温度湿度独立控制空调系统为例，提出了新风系统设计新风量的确定方法，以保证送风不结露为目的所确定的新风量与室内设计相对湿度存在对应关系，并计算出了4种功能房间的设计人均新风量。分析了设计工况新风预冷处理参数和过渡季直接送入室外新风的可行性。

Abstract：
Taking a project in Beijing as an example, puts forward the determine method of the outdoor air rate. There exists a correspondence relationship between the indoor design relative humidity and the outdoor air rate which is determined by anti condensation. Meanwhile, calculates the outdoor air design rate per person of the rooms with four different functions. Analyses the outdoor air pre-cooling treatment parameters under design condition and the feasibility of supplying outdoor air directly into the room in transition seasons.
