| 摘 要： | 为了研究回热器对跨临界CO2压缩喷射系统的影响,本文在自行搭建的跨临界CO2压缩喷射系统实验平台上,通过改变冷却水进口温度分别对带回热器的跨临界CO2压缩喷射系统(TCES-IHX)和不带回热器的跨临界CO2压缩喷射系统(TCES)进行了性能测试.分析和比较了这两种系统模式下制热系数(COPh)、制热量、喷射系数、升压...

| Abstract: | This experimental study presents the effect of internal heat exchanger(IHX) on transcritical CO_2 compression-ejection system.An experimental setup of transcritical CO_2 compression-ejection system was developed.The performance comparison between the transcritical CO_2 ejector systems without IHX(TCES) and with IHX(TCES-IHX) by altering the inlet temperature of cooling water was investigated.Results were analyzed to assess the influence of IHX on the heating coefficient of performance(COP_h),heating capacit... |
