◆Absorbent solution analysis (corrosion inhibitor and performance additive levels)

Figure 72

Period Four described general maintenance requirements for absorption water chillers, including:

νRecommended data for a daily log

νRecommended maintenance for mechanical components, such as the solution and refrigerant pumps, purge, and burner

νRecommended maintenance for heat-transfer surfaces

νRequired analysis of the absorbent solution to ensure acceptable levels of the corrosion inhibitors and performance additives

◆Cooling-water temperature limitations

◆Combination gas-and-electric chiller plants

◆Special considerations for direct-fired chillers

◆Equipment rating standards

Figure 73

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.
