# Industrial Specification: Cooling Unit

## 1. Technical Definition
A component within an Automated Mold Spraying and Cooling System responsible for rapidly reducing mold temperature after spraying operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.0-6.0 MPa (20-60 bar) at 5-15°C coolant outlet temperature**. Failure boundary: **Compressor discharge pressure exceeding 8.3 MPa (83 bar) or evaporator approach temperature dropping below 2°C**, Mechanism: **Refrigerant R134a reaching critical pressure of 4.06 MPa at 101.1°C causes compressor mechanical overload; evaporator approach temperature below 2°C induces refrigerant floodback and liquid slugging**.

### 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.
