混合室直径对带喷射器的跨临界CO2热泵性能影响OA北大核心CSCDCSTPCD
Effect of mixing chamber diameter on performance of transcritical CO2 heat pump system with ejector
通过在跨临界CO2系统中引入喷射器是回收系统节流损失的有效手段.实验研究了混合室直径分别为1.2、1.4、1.6 mm时,对带喷射器的跨临界CO2热泵整体性能以及喷射器自身性能的影响.整个实验中热水进口温度、蒸发温度不变,热水出口温度作为比较基准,在实验中为变量.结果表明,混合室直径对压缩机排气温度影响较小,而其对压缩机排气压力影响较大,当混合室直径为1.6 mm时,压缩机排气压力最小;当混合室直径为1.6 mm时,系统制热系数最高.
The use of ejectors is one of the most promising methods to recover the throttling loss of transcritical CO2 heat pump systems. Experimental investigation on the effect of mixing chamber diameter on the performance of transcritical CO2 heat pump system with ejector was carried out. The mixing chamber diameter was 1.2, 1.4 and 1.6 mm, respectively. The hot water inlet temperature, as well as the evaporating temperature was kept constant in all experiments. Ho…查看全部>>
