摘　　要：为将热泵技术应用扩展至工业加热领域,通过调整压缩机设计、优化热泵流程及系统控制方法,设计了高温热泵并现场测试了其在原油加热场合的应用。研究表明:优化设计的高温热泵系统可提供95℃热水,其1 700 kW加热量可满足工业加热需求;运行中热泵系统制热COP介于3.8到4.8;热泵系统运行过程中压缩机排气温度低于100℃,同时电机温度低于85℃。对高温热泵系统及燃油加热炉的经济性分析显示,热泵系统能耗仅为燃油加热量的44.7%。To expand the usage of heat pump into industrial heating region, a high temperature heat pump prototype was built by using modified twin screw compressor, optimal heat pump structure and system control strategy. A filed test of the heat pump was taken in an oil treatment station and economic analysis was made to explore its energy sav ing potential. The heat pump could provide up to 95 ℃ hot water with a total heating capacity of 1 700 kW and this met industrial heating requirement well. Heating COP changed from 3.8 to 4.8 with temperature changes of heat source. During running time, compressor discharge temperature was lower than 100 ℃ while motor temperature lower than 85 ℃. Economic analysis showed that, for providing same heat quantity, heat pump energy consumption was only 44.7 % of oil-fired heater.
