Workpackage 5: Compressor Development
Development of a safe, highly efficient compressor that can achieve high seasonal performance by:
- Significantly reducing oil and refrigerant charge while guaranteeing safe operation;
- Optimizing for part load operation by utilizing new types of variable speed motors, wet vapour injection and economizer ports;
- Extending the variable speed range of the compressor as low as 15 Hertz.
