notes
Period Four described general maintenance requirements for absorption water
chillers, including:
n Recommended data for a daily log
n Recommended maintenance for mechanical components, such as the
solution and refrigerant pumps, purge, and burner
n Recommended maintenance for heat-transfer surfaces
n Required analysis of the absorbent solution to ensure acceptable levels of
the corrosion inhibitors and performance additives
Period Five presented several considerations for applying absorption water
chillers. These included cooling-water temperature limitations, the advantages
of using combination gas-and-electric chiller plants, special considerations
when using direct-fired chillers, and equipment rating standards.
