Abstract |
In this paper, basic characteristics of the thermally driven pump in supercritical CO2 Rankine cycle system is studied. The thermally driven pump is a refrigerant (liquid CO2)-circulations pump composed of two expansion tanks. Because of no mechanical movement and also no electric consumption, thermal pump is designed to be utilized on power sourcing device compared to feed pump. The experimental result of the thermal pump, flow rate at exit point, and also temperature and pressure, are verified and discuss in this study. It can be found that the flow rate of thermal pump is not stable flow. Though, thermal efficiency of system is higher than using feed pump.
