Compression-resorption heat pumps (CRHP)
Upgrading waste streams with CRHP
Recent Research activities:
NH3-CO2-H2O has been investigated as a potential mixture in a CRHP instead of ammonia-water.
An experimental set-up has been constructed to evaluate the performance of a twin screw compressor compressing in the 2 phase regime.
