Summary

The expressor concept intends to improve the efficiency of water-cooled R134a chillers by 6% by harnessing the power of the flashing liquid that is lost during throttling in the standard refrigeration cycle and using this power directly to compress a fraction of the low-pressure vapour available after the expansion process.
