基于参数归一化的空调负荷计算用气象设计日构造方法

Meteorological design-day construction method for air conditioning load calculation based on parameter normalization

为反映各地区实际近极端气象参数的日变化规律,提出了一种合理构造干球温度、湿球温度和太阳辐照度设计日的方法。该方法赋予各气象要素不同的权重系数,将量纲一干球温度、湿球温度和太阳辐照度等效成归一化参数,在保持与我国现行室外计算参数联合不保证水平一致的情况下,以空调室外计算参数归一化结果为基准进行逐时化设计日的构造。为确保设计日变化趋势准确反映地域气候差异性,以大数据统计性规律提取关键气象特征进而筛选设计日,以期为设计日的确定提供参考。

In order to reflect the daily variation law of actual near-extreme meteorological parameters in different regions, puts forward a method for rationally constructing the design days of dry-bulb temperature, wet-bulb temperature and solar irradiance. This method assigns different weight coefficients to each meteorological element and equalizes the dime.nsionless dry-bulb temperature; wet-bulb temperature and solar irradiance to a normalized parameter. Keeping the outdoor design conditions consistent with joint non-guaranteed duration, uses the normalized result of air conditioning outdoor design conditions as a benchmark to construct the hourly design day. In order to ensure the design day variation trends accurately reflect regional climate differences, extracts the key meteorological features with big data statistical law, and selects the design day, so as to provide references for the determination of design day.
