Introduction: A Shift Toward Waste Heat Utilization

As industries pursue low-energy cooling systems, Hot Water Absorption Chillers (HWACs) are gaining traction by converting waste hot water into effective cooling. Unlike electric chillers, HWACs rely on heat-driven chemical cycles, reducing energy costs and environmental impact.

The Absorption Cooling Process Explained:

HWACs follow a four-step thermodynamic cycle:

• Evaporation: Water absorbs heat and evaporates, creating a cooling effect.
• Absorption: Lithium bromide absorbs the water vapor and maintains system pressure.
• Regeneration: Hot water heats the absorbent to expel refrigerant vapor.
• Condensation: Refrigerant vapor condenses, completing the cycle.

Minimal electricity means HWACs shine in facilities focused on waste heat recovery.

Industries Benefiting from HWACs:

• Power plants, refineries, and manufacturing units use HWACs to maximise waste-heat usage.
• Large commercial buildings and cogeneration facilities integrate HWACs for greater efficiency.

Conclusion: The Future of Industrial Cooling

Hot Water Absorption Chillers represent a smart, sustainable evolution in industrial cooling. By utilising waste heat, they reduce power dependency and carbon footprint—setting a new standard for modern HVAC systems.
