Influence of installation space on exterior wall side on performance of household air conditioners and improvement plan

The recessed louver on the side of the building exterior wall have a small space for the air conditioner, which is not conducive to the heat exchange of the outdoor unit condenser of the air conditioner, and the performance of the air conditioner will be affected. In this paper, the effects of louver type and distance against the wall on the refrigeration performance of household air conditioners are studied through experiments, and the cooling capacity and cooling energy efficiency of air conditioners under different louver types and wall distances are obtained. An improvement plan for improving the refrigeration performance of air conditioners in a narrow space is proposed, and an air guide ring that can be directly installed on the outer unit of the air conditioner is designed. The experimental data show that this solution can effectively improve the performance of household air conditioners installed in small spaces.
