# ReversingValve / FourWayValve

### Purpose & model
|
||
|
||
4-way reversing valve for heat-pump mode swap (heating ↔ cooling). Routes compressor discharge/suction between indoor and outdoor exchangers according to `mode` (or boolean heat/cool).
|
||
|
||
Ideal model: port permutation with negligible ΔP/Δh; real models may add leakage or pressure drop.
|
||
|
||
### Residuals
|
||
|
||
Port coupling residuals matching the selected flow graph for the active mode.
|
||
|
||
### Ports
|
||
|
||
Four refrigerant ports (naming depends on implementation: e.g. compressor discharge/suction, indoor, outdoor).

### Calibration
|
||
|

Usually none; treat as topology switch.
