Summary

The capacity and efficiency of a capacity modulation compressor based on a two-stage rotary compressor are studied experimentally. The test results are compared with results from a numerical analysis (Part ?). The proposed compressor has superior performance and efficiency compared to the conventional bypass-type single-stage compressor. The results satisfy a maximum 3% error requirement for all air conditioning operational conditions. Our results show that for the power mode, the cooling capacity (1% higher than that of the bypass-type) and power consumption (3% lower than that of the bypass-type) of the two-stage rotary compressor are slightly improved. For the saving mode, the cooling capacity (10% higher than that of the bypass-type) and power consumption (8% lower than the bypass-type) are significantly improved. In addition, the results of a loss analysis based on the pressure–volume (P–V) diagram exactly matched the results of the numerical simulation.
