# ScrewEconomizerCompressor / ScrewCompressor
|
|
|
|

|
|
Polynomials: `Polynomial2D` bilinear SST/SDT

## EN

|
### Purpose
|
|
|
|
Twin-screw compressor with **economizer injection** port. Manufacturer performance as **bi-quadratic (bilinear) maps** of SST and SDT.
|
|
|
|
### Performance maps
|
|
|
|
```
|
|
ṁ_suction = z_flow · (a00 + a10·SST + a01·SDT + a11·SST·SDT)
|
|
Ẇ_shaft = z_power · (b00 + b10·SST + b01·SDT + b11·SST·SDT)
|
|
ṁ_eco ≈ eco_fraction · ṁ_suction (or eco poly)
|
|
```
|
|
|
|
JSON coefficient names (CLI):
|
|
|
|
| Mass flow | Power |
|
|
|-----------|-------|
|
|
| `mf_a00`, `mf_a10`, `mf_a01`, `mf_a11` | `pw_b00`, `pw_b10`, `pw_b01`, `pw_b11` |
|
|
|
|
### Built-in presets
|
|
|
|
| `preset` | Meaning |
|
|
|----------|---------|
|
|
| `bitzer_generic_200kw` | Bitzer-like ~200 kW R134a map |
|
|
| `grasso_generic_200kw` | Grasso-like ~200 kW map |
|
|
| (empty) | generic defaults |
|
|
|
|
Explicit `mf_*` / `pw_*` **override** preset values.
|
|
|
|
### Ports
|
|
|
|
| Port | Role |
|
|
|------|------|
|
|
| `suction` / `inlet` | main suction |
|
|
| `discharge` / `outlet` | discharge |
|
|
| `economizer` / `eco` | intermediate injection |
|
|
|
|
### Other parameters
|
|
|
|
| Key | Meaning | Default |
|
|
|-----|---------|---------|
|
|
| `frequency_hz` | drive frequency | 50 |
|
|
| `nominal_frequency_hz` | rated f | 50 |
|
|
| `mechanical_efficiency` | η_mech | 0.92 |
|
|
| `economizer_fraction` | eco flow share | from preset |
|
|
|
|
### Calibration Z
|
|
|
|
| Factor | Default |
|
|
|--------|---------|
|
|
| `z_flow` | **1.0** |
|
|
| `z_flow_eco` | **1.0** |
|
|
| `z_power` | **1.0** |
|
|
| `z_etav` | 1.0 |
|
|
|
|
### UI
|
|
|
|
- Tab **General**: frequency, efficiency, preset
|
|
- Tab **Map (polynomials)**: mf_a** / pw_b** with defaults filled from preset
|
|
- Help documents the bilinear formula
