摘要/Abstract

摘要： 多联机在家装市场的广泛应用,对室内机换热器尺寸提出了更高的要求。换热器铜管、翅片规格和安装角度等对室内机换热能力影响显著。针对某款室内机换热器,首先利用CFD仿真软件研究了不同换热器角度的风场分布,而后分别通过实验研究了Φ7 mm与Φ5 mm管径的换热器风阻与换热能力。CFD仿真研究发现,限定空间内V型54°风场分布最优;实验结果表明,限定空间内V型54°制冷和制热能力最优。考虑机组宽度上增加幅度对机组运输有一定的影响,实际应用的换热器夹角宜在51°~57°范围内。

Abstract: The widespread use of multi-connectors in the home improvement market has put forward higher requirements on the size of indoor unit heat exchangers. The heat exchanger copper tube and fin specifications, installation angle, etc. have a significant impact on the heat transfer capacity of indoor units. The wind field distribution of different heat exchanger angles was firstly studied by CFD simulation software for an indoor unit heat exchanger, and then the wind resistance and heat transfer capacity of heat exchanger with Φ7 mm and Φ5 mm tube diameters were studied experimentally. CFD simulation research has found that the V-shaped 54° wind field distribution is optimal in a limited space. The experimental results indicate that the V-shaped 54 ° cooling and heating capacity is the best in a limited space. Considering that the increase in the width of the unit has a certain impact on the transportation of the unit, the actual angle of the heat exchanger should be within the range of 51°~57°.
