What is Vapour Absorption Cooling?

• Vapour Absorption Technology is an alternative cooling technology that saves money and reduces the environmental impact of your cooling solutions.

• Unlike conventional electricity driven Compression Chillers, Vapour Absorption Machines are driven by low cost / waste heat sources like Steam, hot water, natural gas, fuel oils, agro waste and other similar fuels.

• Since low cost / waste heat is the main driver, operating cost of VAMs is minimal with very attractive payback periods, leading to wide industry popularity

Why Vapour Absorption Cooling?

Ø Alternative and renewable fuels cannot be utilized

Ø Power Cost is rising steadily

Ø Low cost / waste energy needs to be utilized to reduce operating costs

Ø There is a need for CFC free technology

Ø Power availability is becoming a big problem

THE OPERATING PRINCIPLES

Page 14 of 27


How Absorption Chillers work?

Boiling point of the water is a function of pressure. At atmospheric pressure water boils at 100 deg. C. When maintained at high vacuum, water will boil and subcoolitself. The boiling point of the water at 6 mmHg (abs) is 3.7 deg. C.

Lithium Bromide (LiBr) has the property to absorb water (Refrigerant) due to its chemical affinity, directly proportional to concentration & inversely proportional to its temperature.

4/9/2009 5:52:16 PM

Page 16 of 27



Diluted LiBr loses its capacity to absorb water vapour. Thus needs to be reconcentratedusing a Heat Source. Heating may be Steam / Flue gases / Hot water /f uel firing.

4/9/2009 5:52:16 PM

Page 17 of 27



The heating causes the solution to release the absorbed refrigerant in the form of vapour. This vapour is cooled in a separate chamber to become liquid Refrigerant.
