Control method for reducing noise of refrigeration circulation of air conditioner

The present invention relates to a control method for reducing noise produced by short tube of indoor side when the power supply is switched off. Said method includes the following stage: compressor operation stopping stage, switching off power supply of air conditioner and stopping compressor operation; flow path intercepting stage, intercepting medium flow path and preventing medium from flowing toward indoor machine and outdoor machine when the above-mentioned compressor is stopped; and above-mentioned noise preventing stage. 本发明涉及一种减少空调机冷冻循环噪音的控制方法方面的发明，进一步涉及一种关闭电源时能够减少设置在室内侧的短管(short tube)产生的噪音的减少空调机冷冻循环噪音的控制方法。本发明提供一种减少空调机冷冻循环噪音的控制方法，其特征在于，包括：压缩机停止运行阶段、截断流路阶段和噪音防止阶段。上述压缩机停止运行阶段：关闭空调机的电源，压缩机停止运转；上述截断流路阶段：在上述压缩机停止运转阶段中压缩机停止运转时，截断介质流向室外机和室内机侧的介质流路；上述噪音防止阶段：在上述截断介质流路阶段中截断了流路时，防止了上述室内侧产生噪音的现象。
