室外机防护格栅对空调夏季运行能效影响的实验研究

Experimental Study on the Influence of Outdoor Unit Protective Grille on Energy Efficiency of Air Conditioning in Summer Operation

人们通常将注意力集中在空调设备的额定能效,却较少关注室外机安装方式对空调系统实际运行能效的影响。实际上,空调室外机的防护格栅形式在很大程度上会影响整个系统的能效。因此,对防护格栅的设计和安装进行有效改进,以降低空调的能耗,变得尤为重要。为了解决传统空调室外机防护格栅通风换气能力差的问题,设计了一种高效节能通风防护格栅,并通过实验验证了其在提升系统能效比和节能性方面的成效。结果显示,在夏季平均气温维持在35℃的条件下,相较于传统防护格栅,这种节能防护格栅能够将能耗降低33%,系统制冷能效比提高59%。实验表明,本文所设计的防护格栅对于改善凹槽式安装的空调室外机系统性能具备显著效果。

The energy efficiency rating of air-conditioning equipment is typically the focal point for individuals,with less attention often given to the impact of the installation method of the outdoor unit on the actual operational energy efficiency of the air-conditioning system.In actuality,the energy efficiency of the entire system is significantly influenced by the configuration of the protective grille of the air-conditioning outdoor unit.As such,it becomes particularly vital to enhance the design and installation of the protective grille effectively in order to lower the energy consumption of air conditioners.To address the issue of inadequate ventilation and air exchange capability of the protective gilleon the traditionaloutdoorairconditioning unit,atypeofenergyefficient ventilation protection gille was conceptualized.Its efficacy in enhancing the energy efficiency ratio and energy conservation of the system was verified through experimental validation.The outcomes revealed that,when maintaining an average summer temperature of 35℃,this energy-saving protective grlle can reduce energy consumption by 33%,and elevate the system's cooling energy efficiency by 59%when compared to the traditional protective grille.The experimental results demonstrated the effectiveness of the protective grille outlined in this paper in enhancing the performance of outdoor air-conditioning systems featuring a recessed installation design.
