In economised units, before expansion, a portion of liquid is spilled from the soobcooled condensate, expanded to an
intermediate pressure and than flows trough an heat exchanger where, on the other side, flows t he remaining part of
liquid. In this way the soobcooling on the liquid is increased and a small amount of vapour at intermediate value is
produced and injected in the compressor economiser port, so increasing compressor efficiency (reducing discharge
superheat).
