摘　　要：通过试验,分析了室外空气的温湿度对数码涡旋多联式空调系统结霜的影响、除霜工况下压缩机输入功率的变化以及对运行室内机的影响。分析结果表明,影响数码涡旋多联式空调系统结霜的室外环境因素主要为空气的相对湿度,机组在除霜工况下压缩机的输入功率相比于正常运行约减小了60%,而该工况下对室内机的影响与室内机和室外机的距离有关。This paper by experimental study, analyzed the main outdoor environment influence factors when the digital-scroll multi split air conditioning system was on frost, the changes of compressor＇s input power and the impacts of the operating indoor units were also analyzed when the system was on defrost. The results show that influence the digital-scroll multi split air conditioning system＇s frosting main factor of the outdoor environmental factors is outdoor humidity, when the system is on defrosting the compressor＇s input power decreased by 60%, and the indoor units＇ influence is related to the distance with the outdoor unit.
