Updated performance and operating characteristics of a novel rotating spool compressor.

Number: pap. 1378

Author(s) : OROSZ J., KEMP G., BRADSHAW C. R., et al.

Summary

The basic mechanism of the novel rotary spool compressor has been described previously by Kemp et al. (2008, 2010). The device combines various aspects of rotary and reciprocating devices that are currently well understood. A dimensionless variable, the Zsoro number, was developed which represents the geometric configuration of the compressor and has been described previously by Orosz et al. (2012). This number in combination with extensive numerical modeling as described by Bradshaw et al. (2014, 2014a) has allowed for continued improvement in the spool compressor’s efficiency and operating range. Compressors tested have nominal capacities on R410a between 1 and 5 tons of cooling capacity at standard air conditioning conditions. A new platform with improved aspect ratio based on these analyses has been constructed and tested as well as optimization of sub-components such as the tip seals, side seals and discharge porting. The most current prototype compressor is operating with an overall isentropic efficiency which exceeds 80% based on shaft power. This performance is compared against commercial scroll compressors in a similar size range.
