Scroll profile design and shell strength design are important in the development of CO 2 scroll compressors for heat pumps. In order to meet the multi-operating conditions of the heat pump, the non-clearance profile correction method and the clearance profile correction method are analysed, and the clearance profile correction method was adopted to complete the profile design. The safety factor design method was compared with the reliability design method, and the shell of the CO2 scroll compressor for heat pump was designed based on the reliability design method. The test results show that the scroll tooth with clearance correction method meets the design requirements of heating capacity of 4.8kW±10%, the energy efficiency ratio is not less than 4.6, and the shell structure with 99.38% reliability can meet the structural safety requirements.
