摘 要:随着“一带一路”沿线和川藏高原地区的发展,高原低气压地区对空调的使用需求增大,在低气压环境条件下使用的空调器数量将不断增多。因此需要研究不同大气压力下对空调器性能的影响,保证空调器在高原低气压环境下的正常使用。本文通过焓差法,进行不同大气压力下空调器性能测试,获得空调器运行参数,分析不同大气压力下对空调器性能的影响,获得高原低气压环境条件下下性能衰减特性。随着大气压力的下降,空调器制冷运行中空调器的制冷量、EER、风量、出风温度均下降,制热运行中空调器的制热量、COP、风量均下降,出风温度升高。大气压力下降对制热量的影响远大于对制冷量的影响。With the economic and social development of the"The Belt and Road Initiative"and the Westerm Sichuan Plateau,the demand for air conditioners in low pressure areas is increasing,and the number of air conditioners used in low pressure areas will continue to increase.So it is necessary to study the impact of different atmospheric pressures on the performance of air conditioners to ensure the normal use of air conditioners in low pressure areas.This article used the air enthalpy difference method to test the performance of air conditioners under different atmospheric pressures,obtained the operating parameters of the air conditioners,analyzed the impact of different atmospheric pressures on the performance of the air conditioners,and obtained the performance attenuation characteristics under low atmospheric pressure areas conditions.As atmospheric pressure decreases,the refrigeration capacity,EER,air volume,and outlet temperature of the air conditioner decreased during refrigeration operation.As atmospheric pressure decreases,the heating capacity,COP,and air volume of the air conditioner decreased,while the outlet temperature increased,during heating operation.The decrease in atmospheric pressure had a much greater impact on heating capacity than on cooling capacity.
