Abstract: The new national energy efficiency standard has been implemented in 2020, which has greatly improved energy efficiency, improved air conditioning product configuration and cost. At the same time, in order to adapt to the national energy conservation and emission reduction effect, improve air conditioning energy efficiency and reduce air conditioning operation power. The compressor is the core component of air conditioning products and the component with the largest proportion of air conditioning cost and power consumption. By reducing the displacement and single rotor of the compressor, the pressure of larger configuration, significantly increased product cost and power consumption of the air conditioning system caused by the improvement of energy efficiency can be reduced. By mainly analyzing the differences between single and double rotor compressors, the design and application of two single rotor compressors instead of double rotor compressors in compressor vibration and reliability and comfort are given.
