摘要
空调室外计算参数是负荷计算、设备选型等空调系统设计过程必需的基础参数,其取值直接影响系统设计和运行效果。梳理了现行空调室外计算参数确定方法体系,认为现行方法对气象参数间的同时发生性考虑不足。构建了我国5个气候分区典型城市干球-湿球温度联合分布函数,提出了一种以空气状态不保证率确定空调室外计算参数的方法。结果表明,与我国传统方法相比,各城市空调室外计算参数值均有所降低。
Air conditioning outdoor design parameters are the basic parameters in the design process of air conditioning system, such as load calculation and equipment selection. Values of outdoor air design conditions directly impact on the system design and operation effect. Analyses the current methods for determination of outdoor air design conditions, considers that the coincidence between meteorological parameters is neglected to some extent. Establishes a joint distribution function of dry bulb and wet bulb temperature for typical cities from five climate divisions of China, proposes a method for determination of outdoor air design conditions based on non-guarantee rate of air state. The results show that, compared with the current method, all values of outdoor air design conditions decrease in five cities.
