Abstract

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°.
