针对南方湿热地区是我国夏季住宅房间空调器耗能的主要地区及空调器节能研究的重点地区，讨论了在现有国家标准所规定的室内侧空气试验工况值27℃DB/19℃WB 下所设计的房间空调器在湿热地区使用时室内相对湿度偏高的原因，分析了设计进风空气参数对空调器设计的影响，以北京、广州两城市为例选取某型号压缩机进行的不同室内侧空气设计工况下房间空调器的能效比对比表明，以26℃DB/20℃WB 作为室内侧空气设计工况可以更好地适应南方湿热气候条件对房间空调器的性能要求，设计的房间空调器具有更小的设备显热比和更高的能效比，建议修订房间空调器国家标准，考虑不同地区的气候差异对室内侧空气试验工况值做出不同的规定以促进房间空调器节能工作的开展。
針對南方濕熱地區是我國夏季住宅房間空調器耗能的主要地區及空調器節能研究的重點地區，討論瞭在現有國傢標準所規定的室內側空氣試驗工況值27℃DB/19℃WB 下所設計的房間空調器在濕熱地區使用時室內相對濕度偏高的原因，分析瞭設計進風空氣參數對空調器設計的影響，以北京、廣州兩城市為例選取某型號壓縮機進行的不同室內側空氣設計工況下房間空調器的能效比對比錶明，以26℃DB/20℃WB 作為室內側空氣設計工況可以更好地適應南方濕熱氣候條件對房間空調器的性能要求，設計的房間空調器具有更小的設備顯熱比和更高的能效比，建議脩訂房間空調器國傢標準，攷慮不同地區的氣候差異對室內側空氣試驗工況值做齣不同的規定以促進房間空調器節能工作的開展。

In China, room air conditioners (RACs) in residential buildings use large amount of ener-gy. The hot and humid south China area is the major region of RAC energy consumption and also the key area of RAC energy saving study. The reason of higher indoor relative humidity when using RAC designed in condition of indoor air 27 ℃DB/19 ℃WB specified in current national standard was discussed, the effect of indoor air condition on RAC design was also analyzed, two RACs equipped with specific model com-pressor used in Beijing and Guangzhou were theoretically designed, and the energy efficiency ratios were calculated, EER comparison showed that RAC designed in 26 ℃DB/20 ℃WB indoor air condition had smaller equipment sensible heat ratio and higher energy efficiency ratio, it was more proper for hot and hu-mid climate area. It was suggested that indoor air conditions in RAC national standard should be modified according to different climate to save RAC energy consumption.
