摘　　要：通过设计、研究和生产运行实例,分析了低压蒸汽热泵的技术要点及推广价值。研究发现,为了提高热电厂的发电量,背压排汽压力一般确定为0.5MPa。研究开发和推广使用工作蒸汽小于0.5MPa的低压蒸汽热泵供热系统是目前的工作要点。Establishing a combined heat and power generation station to realize heat and electricity supply is a basic model of total energy utilization system. In order to increase the power output, the back pressure of supply steam is normally set at 0.50 MPa. Therefore it is in urgent need to develop and promote the heat supply system of low steam pressure heat pump, in which the steam working pressure is below 0. 50 MPa. The technical key points and the promotion significance of the low steam pressure heat pump system are presented in this paper by analyzing the examples of its designing and operating.
