+
+### Purpose & model
+
+**Microchannel** air-cooled condenser coil. Compact multi-port tubes + air fins. UA from geometry and air/refrigerant side coefficients as coded; runtime residual path follows condenser-style energy balances.
+
+### Residuals
+
+Condenser-like refrigerant + air coupling residuals.
+
+### Ports
+
+Refrigerant + air.
+
+### Calibration
+
+Z-factors on UA/ΔP when exposed (default 1.0).
+
+### JSON
+
+Geometry and air-side setpoints per CLI arm / UI meta (`design_capacity_kw`, face velocity, OAT, …).
