1. Overview
Chiller sizing refers to determining the required cooling capacity needed to remove heat from a process. This capacity is typically measured in kilowatts (kW) ou unités thermiques britanniques par heure (BTU/h).
The basic principle involves calculating how much heat is generated by the equipment and ensuring the chiller can remove that heat efficiently.
Basic Cooling Capacity Formula:
Capacité de refroidissement (kW) = Flow Rate × Specific Heat × Temperature Difference
- Débit (L/minute)
- Specific Heat (Water ≈ 4.186 kJ/kg·°C)
- Temperature Difference (°C)
Accurate calculation ensures stable operation and prevents unnecessary energy consumption.
