| 摘 要： | 电厂循环水温度适中、稳定且蕴含巨大热量,是可利用的环保低位热源,利用热泵技术可有效回收这部分余热,用于北方冬季供热。为寻求能提供80℃以上热水的供热方式,基于自复叠热泵系统,选择R600a/R123非共沸混合工质,通过Matlab和NIST制冷剂物性数据库Refprop 7.1混合编程,模拟了回收电厂循环水余热的实际过程。结果表明,采用混合工质自复叠高温热泵技术回收电厂循环水余热在理论上是可行的。 |

| Abstract: | The circulating water in power plant is a large environment friendly energy source which temperature is moderate and stable.The heat pump technology would be effective for the recycle of the waste heat during the winter in the north.To provide the hot water that the temperature above 80 degree,a kind of auto-cascade heat pump system was proposed,and a new binary non-azeotropic mixing refrigerant composed of R600a/R123 was selected.Then using Matlab and Refprop 7.1 mixed programming,the simulation of theoret... |
| Keywords: | auto-cascade heat pump waste heat of circulating water simulation mixing refrigerant thermodynamic property |
