Economizer (internal)
Source: economizer HX used inside screw-economizer circuits (HeatExchanger<LmtdModel> patterns)
EN
Purpose & model
Internal heat exchanger that subcools liquid / evaporates injection gas for economized screw cycles. Often not a standalone CLI leaf — instantiated inside compressor economizer plumbing or macro components.
Model: LMTD or ε-NTU between liquid line and eco vapor.
Residuals
Standard two-stream HX residuals of the inner model.
Ports
Hot/cold legs as wired by the parent circuit.
Note
For user-facing machines, configure economizer via ScrewEconomizerCompressor + circuit topology rather than a free-floating Economizer node unless the CLI arm exposes it.
FR
But
Échangeur économiseur interne (sous-refroidissement / injection).
Note
Souvent intégré au circuit vis, pas un composant CLI autonome.
