Absorber Type Insights

Lithium bromide-based absorption refrigeration systems are widely preferred for large-scale central air conditioning due to their high efficiency and reliability. Lithium bromide (LiBr) exhibits a strong chemical affinity for water, the refrigerant, allows to maintain vacuum conditions essential for continuous cooling. In these systems, water undergoes flash boiling under vacuum at sub-freezing temperatures to cool the evaporator or chilled water coils. Lithium bromide absorbs the accumulated water vapour thus preserving system stability. This unique mechanism ensures consistent performance and low operational costs.

The growing demand for eco-friendly, energy-efficient cooling solutions without harmful emissions further boosts the adoption of LiBr-based chillers, making them an ideal choice for commercial and industrial applications prioritizing sustainability and efficiency.
