摘　　要：结合发电厂建筑物或房间的功能特点及我国现行暖通设计规范中对室外空气计算参数的规定,确定合理的发电厂蒸发冷却通风空调系统室外空气计算参数。通过对比分析不同的气象数据库,采用典型气象年逐时气象参数统计全国31个主要城市全年不保证50h的湿球温度与同时刻对应的干球温度平均值。将统计得到的参数与其他四组数据作为蒸发冷却空气热湿处理的初状态点,对五组数据经过直接蒸发冷却处理后的出风温度和温降进行对比分析,得出发电厂蒸发冷却空调系统室外空气计算参数为全年不保证50h的湿球温度与所对应的平均干球温度、发电厂蒸发冷却通风系统室外空气计算参数为夏季通风室外计算温度和相对湿度的规定较为合理。Based on the function features of buildings in power plant and the outdoor design parameters in the codes, determine reasonable outdoor design parameters for evaporative ventilation and air conditioning system in power plant. By comparing different weather databases,use thetypical meteorological year hourly weather data for parameters statistic. Get the data not guaranteed 50h wet bulb temperature and the average dry bulb temperature in the same time about 31 cities. Initial air state points include five groups, analysis the outlet air temperature and drop of temperature by the direct evaporative cooling. In the end, outdoor design parameters for evaporative ventilation system are summer ventilation outside design temperature and relative humidity, outdoor design parameters for evaporative air conditioning system are not guaranteed 50h wet bulb temperature and the average dry bulb temperature.
