摘　　要：以热泵制热系数COP为基础,通过增加级和增加效的形式比较压缩式热泵和吸收式热泵在回收循环水余热中的热经济性优劣,主要构建了单级压缩式、双级压缩式、单效吸收式和双效吸收式4种形式的热泵对循环水余热回收热经济性优劣的判定模型,对发电厂循环水余热回收热泵的选型有重要的参考意义。Based on the heating coefficient of the heat pump(COP),this paper compares the advantages and disadvantages in thermal economy of the compression and absorption heat pumps in recovering the waste heat of circulating water by increasing the stage and the effect.An evaluation model for the advantages and disadvantages in thermal economy of waste heat recovery of circulating water of the single-stage compression,two-stage compression,single-effect absorption and double-effect absorption heat pumps is built,which can provide significant reference for the model selection of heat pumps for recovering waste heat of circulating water of the power plant.
