+# AirCooledCondenser
+
+Config type: `"AirCooledCondenser"`  
+Source: air-cooled condenser / coil stack in components

+
+## EN
+
+### Purpose & model
+
+Air-cooled condenser: refrigerant condensation against outdoor air stream. Combines refrigerant-side phase-change energy balance with air-side capacity (fan flow × cp_air × effectiveness or coil model).
+
+```
+Q = ε · C_air · (T_cond − T_air,in)   # schematic ε-NTU air-side form
+```
+
+May wrap or specialize `Condenser` with air secondary defaults.
+
+### Residuals
+
+Similar to Condenser coupled path: refrigerant energy/momentum + air secondary when live ports or rating air stream set.
+
+### Ports
+
+Refrigerant inlet/outlet + air secondary_in/out when 4-port.
+
+### Calibration
+
+`z_ua` default **1.0**; fan speed may be free under head-pressure control.
+
+### JSON
+
+UA / coil geometry / OAT / face velocity / design capacity depending on arm — see CLI `create_component` and example air-cooled chillers.

+**Condenseur à air** : rejet de chaleur vers l’air extérieur.
+
+### Calibration
+
+Z_UA = 1 par défaut ; vitesse ventilateur possible en régulation.
