射流引风空调匀温性能及其影响因素的仿真研究

Simulation study on raise temperature performance of ejection air-conditioner and its influencing factors

采用STAR CCM+软件对立式空调流场进行数值模拟,根据计算结果,分析讨论了射流引风的机理,并对其影响因素进行研究,对比了不同气流形态、风量以及引风通道宽度的引风性能。结果表明,双股气流形式的引风效果明显,提高风量可以提升引风量,但引风量占比在达到一定数值后反而会有所降低,引风通道宽度过大和过小都会减弱射流引风的匀温性能。

Thee software off STAR CCMM+was used in this paper to numericallly simulate tthe flow fieldd of vertical aair incoonditioning.AAccording too the calculattion results,the mechanissm of ejectioon was analyyzed and disccussed,and its nfluencing facctors were stuudied.The ejeection performmance of diffferent air floww forms,air fflow volume aand air ejectioon chhannel width was compareed.The resullts showed thhat the ejectioon effect of ddual-airflow wwas obvious,the ejection aair olume could bbe improved bby increasing the air flow vvolume,but it will decreasee after a certainn air flow vollume value.The Kejvojection performmance of raisiing temperatuure was been wweaken by an inappropriate width of air eejection channnel width.
