SUSTAINABLE RINK CASE STUDYPROJECT SUMMARYO’Leary, Prince Edward Island

Refrigeration Plant Replacement—Ammonia to Opteon™ XP10Background: The O’Leary Community Sports Centre sought ways to leverage government funding for up-grades at the aging arena facility. The community center’s Board of Directors raised additional funding inpartnership with Federal Incentive Funding to undergo the major retrofit project.
The Solution: In 2019 I.B. Storey Inc. executed the firms Triage Assessment framework to develop an action
plan for upgrades prioritizing system stability and sustainability. This led to a follow up engagement for
Expert Rink Engineering Services to design and oversee the implementation of priority action items.
The priority was enhanced safetyincluding lifecycle renewal through the replacement of the aging

refrigeration plant with a new low-maintenance / long-warranty plant using Opteon™ XP10 refrigerant(R513a). Additional benefits included heat recovery infrastructure allowing for future fuel-usage reductions.

Project Challenges Addressed

Project Details & Achievements Safety, Regulatory and Capital: Utilizing Opteon™ XP10
Refrigerant addressed concerns over the presence of toxic
ammonia-refrigerant within the heart of the community andfurther eliminated the requirements for plant room
upgrades to meet current code requirements.

The project consisted of a full plant replacement Operating Cost: Modest utility savings were achieved whichallows the facility to continue to serve the community ataffordable user fees

installing a packaged industrial refrigeration plant withnew pumping system, full heat recovery infrastructure,
low water condenser and direct digital controls all
expertly sequenced.

 Maintenance & Operability: The existing ammonia-based
plant required periodic addition and draining of oil, as well ascompressor overhauls. This placed additional maintenancecosts and operator requirements on the facility, straining thedemands of rink staffing. The new system does not have anyof those requirements allowing for easier on-boarding andtraining of new rink attendants.
