Denison Chilled Water Plant
Heapy Engineering conducted a verification walk-thru of the existing chiller systems and central plant equipment throughout the campus including pumping and piping distribution routes. Most of the buildings on the chilled water system are academic buildings, housing, classroom, offices and labs. The project consisted of:
- Verified the existing chilled water piping distribution loop diagram furnished by University
- Reviewed potential future Chilled Water Loops, Plants, Loop extensions, etc. with University Facilities staff to develop full scope of Chilled Water system analysis.
- Performed a computerized analysis of the existing chilled water piping distribution systems and proposed potential future expansion options to determine optimized pumping and pipe sizing requirements.
To finalize the study, the University received a summary description of the existing Chilled Water systems on campus, an assessment of the remaining useful life of the existing chiller and pump equipment on campus based on ASHRAE service life data, a summary of the computerized chilled water distribution analysis that identifies where the existing system deficiencies were found (ie: pumping, pipe sizing, loop connections/routing, chiller sizing, etc.) and where proposed new cooling loads will require modifications to the existing system (ie: pumping, pipe sizing, loop connections/routing, chiller sizing, etc.).
Subsequently, Heapy Engineering was awarded the design of the Mechanical-Electrical systems and Commissioning Services of the chiller plant addition to the existing campus distributed cooling system. This addition will consist of two 600 Ton chillers and ancillary equipment with space and infrastructure for a third 600 Ton chiller in the future. This project is based on the recommendations of the chilled water system study.
