Absorption Chiller Working Principle

Introduction

An absorption chiller uses heat to drive a refrigeration cycle, offering an alternative to traditional vapor compression chillers.

Working Principle

Explanation of the absorption refrigeration cycle:

• Absorption: Absorbent (usually lithium bromide) absorbs refrigerant (water vapor).
• Desorption: Heat source (hot water or steam) releases refrigerant vapor from absorbent.
• Condensation: Refrigerant vapor condenses into liquid in the condenser.
• Evaporation: Liquid refrigerant evaporates, absorbing heat from the chilled water loop.
