建筑热环境模拟分析用逐时相对湿度生成方法

分别采用对4次相对湿度、4次含湿量、4次露点温度以及4次湿球温度进行直线插值或3次样条插值等8种计算方法生成的逐时相对湿度，从统计学和能耗模拟两个角度，与实测值进行对比分析。分析结果表明，由4次含湿量（或露点温度）进行线性插值计算生成的逐时相对湿度与实测相对湿度吻合较好；并据此给出了由逐时相对湿度根据关联性计算生成逐时含湿量、湿球温度、露点温度的方法。

The method of getting hourly relative humidity for building thermal condition simulation

Series of hourly relative humidity has been given via eight kinds of interpolation, such as interpolation linear and interpolation cubic spline to 6-hour steps relative humidity data, 6-hour steps absolute humidity data, 6-hour steps dew point temperature and 6-hour steps wet bulb temperature. The differences among them have been study on two sides of statistic and simulation. The conclusion that the interpolation linear to absolute humidity has the minimum interpolation error has been drawn. And at the same time the better method of getting hourly absolute humidity, hourly wet bulb temperature and hourly dew point temperature have been given.
