摘　　要：运用室外气象参数匹配室内设计条件、计算建筑冷(热)负荷是暖通设计的基础。随着暖通设计使用的室外气象参数统计方法的更新和扩充,先后调研了中国、美国、日本、英国、德国5部国内外暖通专业现行规范标准的室外气象参数获取与应用方法,分析出我国现行暖通使用的室外气象参数在设计应用中的优劣。我国暖通使用的室外气象参数存在数据旧、不保证率单一等问题,在统计年限更新和不保证率扩充后的新气象数据的基础上,研究数据更新前后对暖通设计中负荷计算的影响。使用DeST软件建立某办公建筑在不同气候分区的负荷计算模型,通过对比气象数据更新前后的负荷模拟结果得出了其对暖通设计计算的影响规律,为气象参数的更新工作提供了应用上的验证与支撑。Using outdoor meteorological parameters to match indoor design conditions and calculating building cold(heat)load is the basis of HVAC design.With the renewal and expansion of the outdoor meteorological parameter statistics used in HVAC design,this paper investigates the outdoor meteorological parameters acquisition and application methods of five domestic and international HVAC standards,including China,the United States,Japan,the United Kingdom and Germany.The advantages and disadvantages of current parameters in design and application in China are analyzed.There are some problems in China,such as old data and single non assurance rate.Based on the new meteorological data after the statistical years are updated and the non-assurance rate is expanded,the impact of data update on load calculation in HVAC design is studied.The DeST software is used to establish the load calculation model of an office building in different climate zones.By comparing the load simulation results before and after meteorological data updating,the influence law on HVAC design and calculation is obtained,which provides application verification and support for the updating of meteorological parameters.
