摘要
游泳馆建筑室内湿负荷大,通风问题备受关注.过渡季室外空气含湿量是通风量计算的基本设计参数,含湿量的取值直接影响了建筑设计的合理性.我国目前使用最广泛的确定过渡季室外计算含湿量的方法是通风曲线法(Ventilation-Curve Method,V-C Method).然而,使用该方法确定的过渡季室外空气含湿量值无法反映不保证小时数,其取值合理性难以评估.提出了一个新的游泳馆过渡季室外空气含湿量取值方法,即典型过渡季法(Typical Transition Season Method,TTS Method).TTS法基于典型气象年(Typical Meteorological Year,TMY)数据挑选过渡季,并以多种不保证小时数计算出室外空气含湿量值,可以很好地表征当地常年气候特征,且能够清楚地反映不保证小时数.研究中选取中国 6 个典型代表城市,通过计算通风量和换气次数对所选含湿量进行了评估,验证了新方法的合理性.结果表明,TTS法得到的含湿量计算出的通风量更符合设计要求.
Abstract
The natatorium's ventilation problem receives much concern because of its large wet load.The outdoor humidity ratio in transition season is the basic design parameter of ventilation calculation,directly affecting the rationality of architectural design.At present,Ventilation-Curve(V-C)method is the most widely used method to determine outdoor humidity ratio in transition season in China.However,due to failure to reflecting hours,the rationality of this value is difficult to assess by employing this approach.This paper presents a new method,Typical Transition Season(TTS)method,for determining outdoor humidity ratio in transition season of natatorium.The TTS method selects the transition season based on the Typical Meteorological Year(TMY)data,and calculates the outdoor humidity ratio with multiple non-guaranteed hours.This can well represent the local perennial climate characteristics and clearly reflect the non-guaranteed hours.In this study,through selecting six typical representative cities in China,the evaluation of the outdoor humidity ratio is achieved through calculating ventilation volume and air changes rate,verifying the rationality of this method.The results show that the ventilation rate,calculated by the humidity ratio obtained from the TTS method,is more suitable for the design re-quirements.
