摘　　要：介绍了溴化锂吸收式热泵的工艺流程,以某300MW抽凝供热机组为例,分析热泵供热前后机组供热能力的变化,对机组节能效益进行计算与分析,并对电厂安装热泵后节能效益的算法进行讨论。结果表明:供热机组安装热泵后,相同抽汽量的情况下机组对外供热能力大大增加;并且在供热量相同的情况下,不同的收益计算方法所得到的节能收益结果相差较大,因此,在计算溴化锂吸收式热泵的节能收益时,应以供热机组实际的运行工况选择合适的计算方法。Introduces the process flow of absorption heat pump, taking a 300 MW pumping unit as an example, analyzes the changes of the heating capacity of the heat pump units, and calculates and analyzes the energy efficiency of the unit. The results show that the heating capacity of the unit is greatly increased with the same pumping capacity, and the difference of the energy saving results obtained by different calculation methods is different. Therefore, it is suitable for the calculation of the actual operating conditions of the heating unit.
