摘　　要：2013年供暖季,对安装在北京某办公建筑中的一台采用中间补气的涡旋压缩机准双级压缩空气源热泵热水机组进行了实际性能测试。对制热量、耗电量等性能参数进行了统计分析,结果表明:该空气源热泵机组在测试期间运行稳定,平均出水温度为42.0℃,供热季节能效比HSPF约为3.20kW·h/(kW·h);在室外温度为-8℃时的能效比仍能保持在2.8kW·h/(kW·h)以上,说明采用中间补气的低环境温度空气源热泵机组在北京作为冬季供暖热源具有较好的运行性能。Tests an air-source heat pump with a compensating scroll compressor of quasi two-stage compression in an office building of Beijing during nearly the whole heating season of 2013.By analysing the heating capacity,energy consumption and other performance parameters,concludes that the air-source heat pump has been running steadily during the testing period,and the average temperature of supply water is 42.0 ℃,and heating seasonal performance factor （HSPF）is about 3.20 kWh/kWh.The coefficient of performance can remain more than 2.8 kWh/kWh when outdoor temperature is -8 ℃,which proves that the air-source heat pump with scroll compressor of quasi two-stage compression shows good running performance as heating device in Beijing.
