Purpose & model
Free-cooling heat exchanger between two liquid loops (e.g. tower water ↔ chilled water) without vapor-compression. Effectiveness–NTU or UA·LMTD between two single-phase streams.
Q = ε · C_min · (T_hot,in − T_cold,in)
Residuals
Two-stream energy balances + optional ΔP per leg.
Ports
Hot and cold in/out (4-port).
Calibration
z_ua default 1.0.
JSON
UA, fluids, optional secondary stream params — see CLI arm.
FR
But
Échangeur de free-cooling (liquide–liquide), sans cycle frigo.
Calibration
