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).
