How Hot Water Absorption Chillers Work:

The working mechanism involves an absorption cycle where water and lithium bromide act as the refrigerant and absorbent. Heat from hot water initiates the cooling process, eliminating the need for mechanical compressors. This makes the system ideal for facilities with cogeneration, solar heating, or waste heat recovery.

Energy Efficiency and Cost Savings:

By using heat sources that would otherwise be wasted, these chillers reduce energy costs and boost sustainability. Their quiet operation and minimal moving parts contribute to lower maintenance and longer equipment lifespan.

Applications of Hot Water Absorption Chillers:

Used in pharmaceuticals, food processing, data centres, and CHP plants, these chillers excel where hot water is available. They’re ideal for eco-conscious industries aiming to reduce greenhouse emissions.

Challenges and Considerations:

Continuous, reliable hot water supply is critical. Though upfront costs may be higher, long-term energy savings outweigh them. Good system design and regular upkeep are vital for performance.

Conclusion:

Hot water absorption chillers turn waste heat into valuable cooling with minimal energy use. Its eco-friendly nature and operational savings make it a compelling choice for modern, sustainability-focused industries.
