### Purpose & model
|
||
|
||
Free-cooling heat exchanger between two liquid loops (e.g. tower water ↔ chilled water) without vapor-compression. Effectiveness–NTU or UA·LMTD between two single-phase streams.
|
||
|
||
```
|
||
Q = ε · C_min · (T_hot,in − T_cold,in)
|
||
```
|
||
|
||
### Residuals
|
||
|
||
Two-stream energy balances + optional ΔP per leg.
|
||
|
||
### Ports
|
||
|
||
Hot and cold in/out (4-port).
|
||
|
||
### Calibration

`z_ua` default **1.0**.
|
||
|
||
### JSON
|
||
|
||
UA, fluids, optional secondary stream params — see CLI arm.
