浅析风冷式空调机组风量分布及其对换热的影响

Discussion of Airflow Distribution of Air-cooled Air-conditioning Unit and the Influence to Heat Transfer

普通风冷式空调机组的室外机分为侧向出风、顶部出风等几种形式,因为出风方式的不同,其风量的分布不同,运行过程中的流场分布也差异很大,这些差异都直接影响机组的换热效果和系统状态,本文通过理论分析和工程经验的演示浅析风冷式空调机组的出风特性,并分析在某些特定工况条件下,其对机组换热的影响。

The outdoor unit of common air-cooled air-conditioning unit has the form of lateral wind out and top wind out, etc.. The differences of air out way, the differences of airflow distribution, and the big differences of flow field distribution during the operation. These differences will influence directivity the heat transfer effect and system state. Through theoretical analysis and engineering experience, this paper analyzes the air-out characteristics; and under some typical operating conditions, the influence of it to the heat transfer.
