# Industrial Specification: Ventilation System

## 1. Technical Definition
A system designed to provide fresh air circulation and temperature control within the operator's cab of industrial vehicles or equipment.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 mÂ³/min airflow, 15-35Â°C temperature control range**. Failure boundary: **Airflow drops below 0.3 mÂ³/min or temperature deviation exceeds Â±5Â°C from setpoint**, Mechanism: **Fan bearing wear exceeding 0.1 mm radial clearance causes imbalance, reducing airflow efficiency by Bernoulli's principle; heat exchanger fouling with &gt;0.5 mm particulate layer increases thermal resistance beyond 0.02 mÂ²Â·K/W**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Condensate accumulation exceeding 50 ml in blower housing | 8 | Fan motor short circuit due to water ingress | Integrated moisture sensor with automatic drain valve activation at 30 ml threshold |
| Filter clogging reaching 250 Pa pressure differential | 8 | Reduced airflow causing compressor overheating above 85Â°C | Differential pressure switch with automatic bypass at 200 Pa |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
