电压缩式热泵和吸收式热泵余热回收分析

Analysis of Waste Heat Recovery of Electric Compression Heat Pump and Absorption Heat Pump

分析了电压缩式热泵与燃气直燃型吸收式热泵在锅炉房烟气深度余热回收系统中的应用。经对比分析,在供热量相同的情况下,使用电压缩式热泵的供热系统的投资额、运行费用和碳排放量均低于使用燃气直燃型吸收式热泵的供热系统,在新建燃气锅炉房中建议优先选用电压缩式热泵作为余热回收的主设备。

The application of electric compression heat pump and gas direct-fired absorption heat pump in deep waste heat recovery system of boiler room flue gas is analyzed.After comparative analysis,under the same heating capacity,the investment,operating costs,and carbon emissions of heating system using electric compression heat pump are lower than those using gas direct-fired absorption heat pump.It is suggested to prioritize the use of electric compression heat pumps as the main equipment for waste heat recovery in newly built gas boiler rooms.
