+## EN
+
+### Purpose & model
+
+Finned-tube outdoor coil. Geometry (tubes, rows, fin pitch, face velocity) feeds air-side heat transfer estimates; refrigerant side condenses with subcooling target options.
+
+Correlations: coil/fin air-side Nu–Re style relations as implemented in the geometry stack (see source for exact correlation names).
+
+### Residuals
+
+HX residual set analogous to Condenser + coil geometry parameters for UA construction.
+
+### Ports
+
+Refrigerant + air secondary ports.
+
+### Calibration
+
+`z_ua` / geometry scales — default unity.
+
+### JSON (main)
+
+Tube OD, rows, fin density, face velocity, OAT, design capacity — see componentMeta FinCoilCondenser params.
