摘　　要：现行GB50736—2012《民用建筑供暖通风与空气调节设计规范》缺少海域室外空气计算参数.基于1985—2014年ERA5数据生成阳江近海室外空气计算参数.首先以中国气象局提供的阳江地面实测数据为基准,通过偏差分析验证了基于ERA5数据生成室外空气计算参数是可行的.然后基于ERA5数据生成沿阳江陆地(21.9°N,111.96°E)减小六次0.25°纬度的海域室外空气计算参数,包括夏季空气调节室外计算干球温度、湿球温度、日平均温度,冬季空气调节室外计算温度、相对湿度,夏季通风室外计算温度、相对湿度,冬季通风室外计算温度.由阳江陆地(21.9°N,111.96°E)至海域(20.4°N,111.96°E),夏季空气调节室外计算干球温度降低了3.6℃,冬季空气调节室外计算干球温度升高了7℃,夏季通风室外计算相对湿度升高了12.5%.如果海域选用就近陆地城市的室外空气计算参数,将影响设备选型.The GB50736—2012“Design code for heating ventilation and air conditioning of civil buildings”lacks the outdoor design conditions in sea areas.This paper generates outdoor design conditions for Yangjiang offshore based on ERA5 data from 1985—2014.Firstly,based on the ground measured data of Yangjiang provided by the China Meteorological Administration,the deviation analysis verified that it is feasible to generate outdoor design conditions based on ERA5 data.Then,based on the ERA5 data,the outdoor air calculation parameters for the sea area with six 0.25°latitude decreases along the Yangjiang land(21.9°N,111.96°E)were generated,including the outdoor design dry-bulb temperature,wet-bulb temperature and mean daily temperature for summer air conditioning,outdoor design temperature and relative humidity for winter air conditioning,outdoor design temperature and relative humidity for summer ventilation,and outdoor design temperature for winter ventilation.From Yangjiang land(21.9°N,111.96°E)to the sea(20.4°N,111.96°E),the outdoor design dry-bulb temperature for summer air conditioning decreases by 3.6℃,and the outdoor design dry-bulb temperature for winter air conditioning increases by 7℃,and the outdoor design relative humidity for summer ventilation increases by 12.5%.If the sea area selects the outdoor design conditions of the nearby land city,it will affect the equipment selection.
