# Industrial Specification: Air Handling Unit

## 1. Technical Definition
A device that conditions and circulates air as part of a heating, ventilation, and air conditioning (HVAC) system

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 kPa static pressure, 1.5-15 m/s air velocity, -20°C to +80°C air temperature**. Failure boundary: **3.0 kPa static pressure (fan motor overload), 18 m/s air velocity (vibration-induced structural fatigue), 90°C air temperature (belt degradation threshold)**, Mechanism: **Bernoulli's principle violation causing pressure differential collapse, Reynolds number exceeding 5000 inducing turbulent flow separation, Arrhenius equation thermal degradation of elastomeric components**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| U | Heat Transfer Coeff | Engineering Constant |
| A | Area | Engineering Constant |
| \Delta T_{lm} | LMTD | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Condensate formation below 12°C dew point | 8 | Coil frost accumulation exceeding 5 mm thickness | Integrate proportional-integral-derivative controlled electric preheater maintaining coil surface at 15°C |
| Coriolis force imbalance at 1200 RPM fan speed | 8 | Shaft deflection exceeding 0.1 mm causing bearing seizure | Implement dynamic balancing with ISO 1940 G2.5 standard and laser-aligned coupling |
