【摘要】 对长沙市某酒店的建筑能耗进行了调查,分析了该酒店的用电情况及空调系统能耗。通过分析和测试表明:在整个建筑能耗中,空调能耗占到总能耗的50%左右;整个建筑的用电高峰和空调的用电高峰主要集中在6～8月;制冷系统实际运行和设计值偏差太大,实际制冷能力远低于额定值;水系统设计不合理,存在大流量小温差现象。指出了空调系统在设计、运行和管理方面存在的问题。在酒店的整个运行过程中节能潜力最大的是空调系统,空调电耗中又以制冷机和水泵影响最大。 【Abstract】 There is a survey on the building energy consumption for a hotel in Changsha,analyzing its electricity and air-conditioning energy consumption.The results from the analysis and testing show that: In the whole building energy consumption,the conditioning energy consumption accounted for about 50% of the total energy consumption; electricity consumption peak of the building and air-conditioning con-centrated from June to August.The large gap exists between the designed value and practical operation value of refrigeration system,the actu-al cooling capacity is far less than the specified value;?It is unreasonable for design in water system,so there is the phenomenon of large flux and low temperature difference.And various problems on the design,operation and management of the air-conditioning system are expound-ed.In the hotel,the greatest potential energy-saving system is air-conditioning system in the entire operation,and refrigerator and pumps have the greatest impact on the air-condit 【关键词】 建筑能耗; 空调能耗; 节能 【Key words】 building energy consumption; air-conditioning energy consumption; energy-saving
