A Vapor Absorption Machine (VAM) is an advanced cooling technology

It leverages heat instead of electricity via an absorbent‑refrigerant pair like lithium bromide–water or ammonia–water.

How Vapor Absorption Machines Work

The four-stage absorption cycle: evaporation, absorption, regeneration, condensation—driven by heat rather than compression.

Benefits and Applications

• - Lower energy use and carbon emissions
• - Uses eco‑friendly refrigerants
• - Quiet and low‑maintenance for large‑scale settings

Conclusion

VAM systems are key to energy conservation and sustainable cooling, increasingly adopted in modern HVAC applications.
