空调器室内机风道结构优化设计与性能分析

Optimal design and performance analysis of air duct structure for air conditioner indoor units

高能效的空调产品一直是市场竞争的主流,但随着技术成熟和产品趋于定型,尤其是对于结构较为简单的家用空调内机而言,难以实现能力能效的快速提升。为此,通过优化风道,加大贯流风扇,打破现有产品结构堡垒,提高空调内机风量,并优化蒸发器管路设计,达成节能目标。实验结果表明,新开发的空调机型符合当下的市场节能趋势,其风量最高可增大204 m^(3)/h,对中高频测试点的单点能效有明显提升,约提高4%,但增加了低频测试点负荷,单点能效最高下降1.34,从而季节能效与原机型相当。

High-efficiency air conditioning products have been the mainstream of market competition.However,with the maturity of technology and the trend of product standardization,especially for the relatively simple structure of household air conditioning indoor units,it is difficult to achieve the rapid improvement of capacity and energy efficiency.Therefore,optimizes the air duct,increases the cross-flow fan,breaks the existing product structure fortress,improves the air volume of the air conditioning indoor unit,and optimizes the evaporator pipeline design to achieve the energy-saving goal.The experimental results show that the newly developed air-conditioning model is in line with the current market energy-saving trend,and its air volume can be increased by up to 204 m^(3)/h,and the single-point energy efficiency of the medium and high frequency test points is significantly improved,which is increased by about 4%,but the load of the low-frequency test points is increased,and the single-point energy efficiency is reduced by up to 1.34,so that the seasonal energy efficiency is comparable to that of the original model.
