A Comparison of Traditional Degree-Day and Variable-Base Degree-Day Predictions with Measured Consumption of 20 Houses in the Denver Area 丹佛地区20栋房屋的传统学位日和可变基准学位日预测与实测消费量的比较
对丹佛大都会区20户住宅的传统修正度日法和可变基准度日法的两种变体预测的供暖消耗量与计量燃气消耗量中与天气相关的部分进行了比较。传统方法预测的平均消耗量是计量使用量的1.82倍,VBDD方法的平均预测量分别是计量使用量的1.45倍和1.44倍。据计算,这20所房屋的平均平衡温度分别为59.8华氏度(15.4摄氏度)和56.5华氏度(13.6摄氏度),而回归账单数据显示平均温度为57.5华氏度(14.2摄氏度)。计算消耗量和计量消耗量之间的差异似乎是由于BLC/n的计算值系统性地大于经验值,以及增益利用不完全造成的。 单位:双引文:研讨会,ASHRAE交易,1985年,第91卷,pt。你好,檀香山2B
The heating consumption predicted by the traditional modified degree-day method and variants two of the variable-base degree-day method is compared with the weather related portion of metered gas consumption for 20 houses in the Denver Metropolitan Area. The average consumption predicted by the traditional method was 1.82 times the metered use, and the average prediction of the VBDD approaches was 1.45 and 1.44 times the metered use, respectively. The average balance temperature of the 20 houses was calculated to be 59.8 F (15.4°C) and 56.5 F (13.6°C), respectively, while regressed billing data indicate an average of 57.5 F (14.2°C). The discrepancy between calculated and metered consumption appears to be due to calculated values of BLC/n which are systematically larger than empirical values and to incomplete gain utilization.Units: Dual
