Abstract: The requirement of single-rotor compressor application on floor-standing air conditioner continues to grow. However, the severe vibration of single-rotor compressor always occurs with its inherent attribute, especially at low speed with unsuitable control, and it will aggravate the stress of pipe, so the extensive application is impeded. The scheme of four-way valve pipes and one control method of vibration reduction was designed. After comparing the stress of suction pipe and exhaust pipe with the target stress, the results show that the single-rotor compressor can apply to 2P floor-standing air conditioner. The scheme can provide support to the application research on floor-standing air conditioner with single-rotor compressor.
