【摘要】 于2008年夏季对长沙市10栋不同类型公共建筑的空调系统冷热源、节能技术应用、运行管理方法、建筑热湿环境参数以及室内人员热舒适性等方面进行了现场详细调查与实测。得出被调查建筑空调冷热源主要包括直燃型溴化锂机组、水冷螺杆式机组和风冷热泵,冷热源能源方式以电和天然气为主。各建筑内热湿环境良好,大部分人对所处环境总体满意率较高。针对调查中发现的问题,对该地区公共建筑空调系统节能措施的应用和热湿环境的改善提出了一些建议。 【Abstract】 In summer of 2008,cooling/heating sources of air-conditioning systems,energy-saving technologies,operation methods,thermal criteria and thermal comfort of occupants were investigated in 10 different public buildings of Changsha.Results show that cooling/heating sources of air-conditioning systems mostly consist of Li-Br absorption refrigerating machine,water-cooled screw chiller and air-cooled heat pump.Electricity and gasoline are the main source types.Thermal environments of every building are good,and most occupants satisfy with the building environments.According to the problems discovered by investigation,energy-saving measures and improvement of thermal environments are advised. 【关键词】 公共建筑; 冷热源; 节能; 热环境 【Key words】 public buildings; cooling/heating sources; energy-saving; thermal environment
