【摘要】 采用数理统计方法,根据哈尔滨集中供热系统热力站实际运行数据,研究天气因素(室外温度、风速、天气条件)、建筑因素(建筑节能状况、建筑功能)、系统因素(楼内供暖系统形式、室内散热装置类型)对热力站单位面积耗热量的影响。室外温度与单位面积日耗热量为高度负相关。室外风速与单位面积日耗热量相关性不显著,可忽略。在消除室外温度影响后,天气条件可显著影响单位面积日耗热量。雨雪天-晴天单位面积日耗热量差异显著。雨雪天-阴天及多云、阴天及多云-晴天两对比较对象的单位面积日耗热量差异不显著。节能建筑热力站比非节能建筑热力站的单位面积供暖期耗热量低88.0 MJ/m~2,差异显著。3种建筑功能热力站间单位面积供暖期耗热量差异均显著,由高到低的顺序为居住建筑热力站、混合建筑热力站、公共建筑热力站。3种楼内供暖系统形式热力站间单位面积供暖期耗热量差异不显著。散热器热力站、混合散热装置热力站分别比地面辐射供暖热力站的单位面积供暖期耗热量高84.94、51.10 MJ/m~2,差异显著。散热器热力站与混合散热装置热力站的单位面积供暖期耗热量差异不显著。与节能建筑相比,非节能建筑不同楼内供暖系统形式热力站间单位面积供暖期耗热量差异性更加显著。对于非节能建筑,3种楼内供暖系统形式热力站间单位面积供暖期耗热量差异均显著,由高到低的顺序为按户分环系统热力站、混合供暖系统热力站、垂直式系统热力站。更多还原

【Abstract】 Using mathematical statistical methods,according to the actual operating data of the heating station of the Harbin central heating system,the influence of weather factors( outdoor temperature,wind speed and weather conditions), building factors( building energy-saving efficiency and building functions),system factors( building heating system form and indoor heat release device type) on the heat consumption per unit area of the heating station is studied.Outdoor temperature and daily heat consumption per unit area are highly negatively correlated,that is,the lower the outdoor temperature,the higher the daily heat consumption per unit area. The correlation between outdoor wind speed and daily heat consumption per unit area is not significant and can be ignored. After eliminating the influence of outdoor temperature,weather conditions can significantly affect the daily heat consumption per unit area. There is a significant difference in daily heat consumption per unit area between rainy/snowy days and sunny days. There is no significant difference in the daily heat consumption per unit area between the rainy/snowy days and overcast/cloudy days, the overcast/cloudy days and sunny days. The heat consumption per unit area of energysaving building heating station is 88. 0 MJ/m~2 lower than that of non energy-saving building heating station,and the difference is significant. There are significant differences in heat consumption per unit area between the three types of building heating stations during the heating period,and the order from high to low is residential building heating station,mixed building heating station and public building heating station. There is no significant difference in the heat consumption per unit area between the three types of heating stations in the building heating system form during the heating period.The heat consumptions per unit area of the radiator heating station and the hybrid heat release device heating station are 84. 94 and 51. 10 MJ/m~2 higher than that of the ground radiant heating station respectively,and the difference is significant. There is no significant difference in heat consumption per unit area between the radiator heating station and the hybrid heat release device heating station during the heating period. Compared with energy-saving buildings,non-energy-saving buildings have more significant differences in heat consumption per unit area between heating stations in different building heating system forms. For non-energysaving buildings,there is a significant difference in heat consumption per unit area between the three types of heating stations in the building heating system form.The order from high to low is heating station of ring system by household,hybrid heating station and vertical heating station.更多还原
