Experimental and theoretical study of hermetic CO2 scroll compressor.

Author(s) : HASEGAWA H., IKOMA M., NISHIWAKI F., et al.

Summary

A prototype CO2 scroll compressor with a displacement volume of 7.23 cc was fabricated by reducing the wrap height of a medium capacity scroll compressor. The performance of the prototype was then measured under cooling conditions using the transcritical CO2 cycle. The volumetric efficiency and the compressor efficiency of the prototype were improved as operating speed increased. The volumetric efficiency of the CO2 scroll compressor was only slightly lower than for HFC-410A. Next, a theoretical analysis of the prototype was carried out by constructing an analytical simulation. The results closely matched the experimental results.
