Process Description
Some liquids like water have a great tendency for absorbing
large amount of certain vapors (NH3) and reduce the total volume quite. The absorption chiller refrigeration system differs basically from vapor compression system only in the
method of compressing the refrigerant.
In the absorption refrigerating system, the compressor is
replaced with an absorber, generator and pump. Figure 6.7 shows the schematic
diagram of a vapor absorption refrigeration system.
Ammonia vapor is extracted from the NH3 strong solution at high pressure in the
generator by an external heating source. In the rectifier, the water vapor
which carried with ammonia is removed and only the dried ammonia gas enters
into...
