SANYO’s CO2 rotary compressor was the world’s first hermetic compressor to use a two-stage compression mechanism to disperse the differential pressure and compression load. By dividing one compression into two, high reliability and efficiency can be obtained. Its internal intermediate pressure structure makes it easy to design the shell while considerably reducing its thickness. This innovative shell design and a compact concentrated winding motor ensure a compact size and light weight.
The combination of a DC brushless motor, which helps to improve the motor efficiency, and an optimized dimension of the 2-stage compression mechanism leads to a higher overall system efficiency. The compressor is also resistant to high working pressures and large pressure differences occurring in transcritical CO2 cycles. By adding intermediate cooling through the 2-stage compression mechanism and a suction line heat exchanger, it is an optimal solution for refrigeration and cooling purposes, where CO2 compressors in the past showed lower levels of performance compared to conventional models.
SANYO’s innovative 2-stage rotary compressor technology will be an integral part of 5,000 beverage coolers installed at the Beijing Olympic Games this summer, following its successful application during the Olympics in Athens and Torino, as well as the FIFA World Cup. Moreover, SANYO’s compressors have been successfully applied in thousands of Japanese vending machines.

“SANYO’s experience shows that CO2 can perform better or at an equivalent efficiency at least, compared to conventional systems if handled correctly and adding some ideas such as two stage compression, intercooler, suction line heat exchanger, variable refrigerant flow control, and so on. We hope that our products will contribute to a transition towards climate-friendly commercial refrigeration and heating,” says Gaku Shimada, Manager at SANYO's Compressor Division - Strategic Business Planning Section.
