摘要
通过对某款36000 Btu/h能力段家用定速空调器,批量生产后抽检过程中出现制冷量波动根据抽检结果判定不合格的情况,从蒸发器、冷凝器、压缩机等方面对空调器能力波动原因制定了6个优化方案进行实验研究.结果表明原型机蒸发器流路过热情况与蒸发器表面风速分布一致,将蒸发器流路由原9进9出优化为10进10出的方案对整机性能波动情况有较好改善作用,同时基于该方案更换某品牌 26.5排量压缩机后显著改善了整机能力波动情况,能力提升高达4.7％,能效提升高达7.1％.本研究为整机能力波动的情况提供了有效的解决方案,同时为同行后续遇到类似问题提供了相关指导.
Abstract
An experimental study was conducted to investigate the reasons for the fluctuation in the cooling capacity of a certain 36000 Btu/h capacity home air conditioner,which was determined to be non-compliant based on the inspection results during the mass production quality control.Six optimization schemes were proposed and experimentally studied from the perspectives of the evaporator,condenser,and compressor to address the reasons for the fluctuation in the cooling capacity of the air conditioner.The results show that the overheating situation of the prototype evaporator flow path is consistent with the wind speed distribution on the evaporator surface.Optimizing the evaporator flow path from 9 inlets and 9 outlets to 10 inlets and 10 outlets has a good effect on the fluctuation of the whole machine performance.At the same time,replacing a certain brand's 26.5-liter compressor based on this scheme can significantly improve the fluctuation of the whole machine's performance,with an increase in capacity of up to 4.7％and an increase in energy efficiency of up to 7.1％.This study provides an effective solution for the capacity fluctuation of the whole machine,and provides relevant guidance for the peers to encounter similar problems in the future.
