# Industrial Specification: Humidity Control System

## 1. Technical Definition
A subsystem within an environmental control chamber that regulates and maintains specific humidity levels.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **20-80% RH at 25°C, dew point range -10°C to +20°C**. Failure boundary: **Condensation at dew point differential &gt;2°C or sensor saturation at 100% RH for &gt;30 seconds**, Mechanism: **Water vapor saturation exceeding psychrometric capacity, leading to liquid water formation on chilled mirror sensors or electronic corrosion**.

### 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.
