| Value Share (2035) | 92.5% |
Lithium bromide-based absorption refrigeration systems are highly efficient, making these ideal for large-scale central air conditioning applications. The high chemical reactivity of lithium bromide (LiBr) with water (as a refrigerant) helps the compound to absorb water with a very high affinity.
Water, in that respect, is subjected to flash boiling under vacuum conditions at temperatures invariably below freezing point as a way of cooling the evaporator or the chilled water coils. As water vapor collects and threatens to disturb the vacuum, lithium bromide absorbs it, preserving the vacuum conditions required for continuous operation. This procedure makes lithium bromide a key component for assuring the performance and dependability of absorption chillers.
The lithium bromide segment is projected to witness significant growth over the forecast period with a revenue of USD 2.8 billion. It is set to rise at a CAGR of 6% through 2035.
