能耗监管体系在实验动物设施应用和节能措施评价

目的 监测实验动物设施能耗情况,评估节能措施的成效,为实验动物设施的能耗实时监测、管理以及节能措施提供参考.方法 应用节能监管体系对浙江大学实验动物设施的年度用电、用汽和供冷/热等能耗情况进行系统监测和分析.将实验动物设施单位面积能耗与同时期其他建筑进行比较分析,评定实验动物设施总体能耗水平.并对蒸汽系统改造由管道供汽改成自备电蒸汽锅炉供汽前后各6个月的能耗的情况进行比较分析.结果 实验动物设施年度用电、用汽和供冷/热等能耗分别为1.725 GWh、12244.90 GJ和1.497 GWh,分析总能耗可归结为用电和用汽两种,分别为2.783 GWh和12553.29 GJ.核算后监测期内实验动物设施单位面积能耗耗能量为其他建筑的8.52至21.88倍.蒸汽系统改造前后使用管道供汽和自备电蒸汽锅炉的能耗情况分别为9925.00 GJ和2651.57 GJ,节能效率高达73.3％.结论 节能监管体系能用于实时监测实验动物设施用电、用汽和供冷/热等能耗情况,可系统反映整体与局部的能耗情况,并可对节能改造措施进行成效分析.针对实验动物设施自备电蒸汽锅炉供汽方式从节能角度考虑明显优于管道集中供汽.

Application and Energy Conservation Methods Assessing in Laboratory Animal Facility by Energy Monitoring System

Objective To establish a method for energy montoring and assessing energy conservation methods in laboratory animal facilitiy. Methods Annual energy consumption situation of laboratory animal facilitiy was assessed by an energy monitoring system. The total energy consumption of electricity, steam, heat and cooling capacity, etc. were recorded and analysised. The square meter energy con- sumption of the facility was calculated and compared with other buildings in our campus. Two different steam supply ways, pipeline and electric steam boiler, were measured by the energy monitoring system. Results Consumption of electricity, steam, heat and cooling capacity were 1.725 GWh, 12244.90 and 1.497 GWh, respectively. The total electric and steam consumption of the facility were 2.783 GWh and 12553.29 GJ. Compared with 4 different buildings monitored, the energy consumption of animal facility was 8.52 to 21.88 times more. The system showed steam consumption of two different supplying ways were 9925.00 GJ and 2651.00 GJ, respectively. Conclusion The energy monitoring system could realtime reflect the energy consumption of our laboratory animal facilities. It was availible for energy consumption statistics and energy-saving administration. According to our results, electric steam boiler was a more economical way compared with pipe supplying.
