Double Effect Steam Fired
In this kind of chiller, absorbent (Lithium Bromide) will be concentrated in two stages. Concentration in stage one can be done in high temperature generator by feeding steam from steam boiler. Concentration in stage two can be done in low temperature generator by steam which is generated in stage one. So we call it double effect. Note that this type of chiller needs steam flow with about 8 bar (120 PSI) pressure.
Because of special conditions which is needed for producing a steam flow with 8 bar pressure, the application of these chillers are specific.
