### Core Types
- `WasmPressure` - Pressure in Pascals or bar
- `WasmTemperature` - Temperature in Kelvin or Celsius
- `WasmEnthalpy` - Enthalpy in J/kg or kJ/kg
- `WasmMassFlow` - Mass flow rate in kg/s
- `WasmPressure` — Pressure in Pascals (constructor validates non-negative)
- `new(pascals)` — from Pascals
- `from_bar(bar)` — from bar
- `WasmTemperature` — Temperature in Kelvin (constructor validates non-negative)
- `new(kelvin)` — from Kelvin
- `from_celsius(celsius)` — from Celsius
- `WasmEnthalpy` — Enthalpy in J/kg (constructor rejects NaN)
- `new(joules_per_kg)` — from J/kg
- `from_kj_per_kg(kj_per_kg)` — from kJ/kg
- `WasmMassFlow` — Mass flow in kg/s (constructor rejects NaN)
- `new(kg_per_s)` — from kg/s
All types have a `toJson()` method returning a JSON string.
### Components
- `WasmCompressor` - AHRI 540 compressor model
- `WasmCondenser` - Heat rejection heat exchanger
- `WasmEvaporator` - Heat absorption heat exchanger
- `WasmExpansionValve` - Isenthalpic expansion device
- `WasmEconomizer` - Internal heat exchanger
- `WasmCompressor` — AHRI 540 compressor model
- `new(fluid, speed_rpm, displacement, efficiency, m1..m10)` — all 10 AHRI coefficients required
- `WasmCondenser` — Heat rejection heat exchanger
- `new(ua)` — thermal conductance in W/K (must be positive)
- `WasmEvaporator` — Heat absorption heat exchanger
- `new(ua)` — thermal conductance in W/K (must be positive)
- `WasmExpansionValve` — Isenthalpic expansion device
- `new(fluid, capacity_kW)` — pass 0 for no capacity limit
- `WasmPipe` — Transport pipe
- `new(fluid, length, diameter, density, viscosity)` — all parameters required
Each component has an `into_component()` method that converts it to a generic `WasmComponent` for adding to the system.
### Solver
- `WasmSystem` - Thermodynamic system container
- `WasmNewtonConfig` - Newton-Raphson solver configuration
- `WasmPicardConfig` - Sequential substitution solver configuration
- `WasmFallbackConfig` - Intelligent fallback solver configuration
- `WasmConvergedState` - Solver result
- `WasmSystem` — Thermodynamic system container
- `add_component(component)` → node index
- `add_edge(from_idx, to_idx)` — connect two component nodes
- `finalize()` — finalize topology before solving
- `solve(config)` — solve with fallback strategy
- `solve_newton(config)` — solve with Newton-Raphson only
- `get_node_result(idx)` — get thermodynamic state at a node after solving
- `WasmNewtonConfig` — Newton-Raphson solver configuration
- `set_max_iterations(n)`, `set_tolerance(tol)`
- `WasmPicardConfig` — Sequential substitution solver configuration
- `set_max_iterations(n)`, `set_relaxation_factor(omega)` — omega clamped to (0, 1]
- `WasmFallbackConfig` — Intelligent fallback solver configuration
- `set_fallback_enabled(bool)`, `set_return_to_newton_threshold(f64)`, `set_max_fallback_switches(usize)`
- `WasmConvergedState` — Solver result with `converged`, `iterations`, `final_residual`, `status`
### Fluid Management
- `list_available_fluids()` — returns array of available fluid names
- `load_fluid_table(json_string)` — load a custom fluid table from JSON

```
## Performance
@@ -115,17 +189,8 @@ npm test
## Limitations
- **CoolProp unavailable**: The WASM build uses TabularBackend with pre-computed tables. CoolProp C++ cannot compile to WebAssembly.
- **Limited fluid library**: By default, only R134a is embedded. Additional fluids can be loaded from JSON tables.
## Loading Custom Fluid Tables
```javascript
import { load_fluid_table } from '@entropyk/wasm';
// Load a custom fluid table (generated from the entropyk CLI)
const r410aTable = await fetch('/path/to/r410a.json').then(r => r.text());
await load_fluid_table(r410aTable);
```
- **Limited fluid library**: By default, only R134a is embedded. Additional fluids can be loaded from JSON tables generated by the entropyk CLI.
- **Custom fluid tables**: `load_fluid_table` validates the table but registration in the global backend requires additional infrastructure (planned).
