How Absorption Chillers Work in Facilities Management
Absorption chillers play a crucial role in facilities management by providing efficient cooling solutions. But how exactly do these innovative systems work?
At the heart of an absorption chiller is a refrigeration cycle that utilizes a chemical process to generate cooling. Unlike traditional mechanical chillers that rely on compressors, absorption chillers use heat energy to drive the cooling process.
The key components of an absorption chiller include an absorber, generator, condenser, and evaporator. The process starts with the absorber where a solution known as the absorbent absorbs refrigerant vapor coming from the evaporator. This causes a reduction in pressure and temperature in the evaporator.
Next, the absorbent-rich mixture flows into the generator where it is heated using various heat sources such as steam or natural gas. The absorbed refrigerant is then released from the absorbent through evaporation.
In the condenser, this vapor is cooled and condensed back into liquid form while releasing heat to another fluid medium like air or water. This high-pressure liquid enters the evaporator where it expands and cools down due to reduced pressure before returning to repeat the cycle.
By utilizing waste heat or other sustainable energy sources for driving their operation instead of electricity-intensive compression systems found in traditional chillers, absorption chillers offer numerous benefits including lower operating costs and reduced environmental impact.
