The director of facilities, Daniel Larrabee, came to CCI to discuss two of his older Trane chillers and what options he might have for replacement. These chillers were 15-year-old air-cooled chillers, but the condenser coils were in very bad shape. The units were extremely loud and very inefficient.
We began by looking at the energy usage of the existing chillers. We began by looking at the energy usage of the existing chillers and compared this with that of new chillers such as Trane, York, and McQuay. After reviewing the chiller performance, we selected 2 York chillers with variable speed drives. We then negotiated a 10-year warranty on both chillers so Bishop Gadsden would know exactly the amount of dollars that would be spent over this time period. Additionally, with the energy savings generated from the new chillers, SCE&G contributed a rebate check of $125,000 that helped pay for the project.
