# Industrial Specification: Headers/Distributors

## 1. Technical Definition
Components that collect and distribute refrigerant flow within condenser coils

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.5 MPa (5-35 bar)**. Failure boundary: **4.2 MPa (42 bar) internal pressure causing permanent deformation of distributor channels**, Mechanism: **Plastic deformation due to yield strength exceedance of aluminum alloy 6061-T6 (276 MPa yield strength) under refrigerant pressure loading**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Refrigerant flow maldistribution exceeding 15% deviation from design distribution | 8 | Localized frost formation on downstream evaporator sections | Integrate flow sensors with PID-controlled metering valves at each distributor outlet |
| Corrosion-induced pitting reaching 0.8 mm depth in distributor internal surfaces | 8 | Refrigerant leakage at 0.05 kg/s exceeding ASHRAE Standard 15 limits | Apply 50 μm thick PTFE coating on all internal surfaces exposed to R-410A refrigerant |
