According to the City of Lethbridge, its Facility Services department has modernized the City’s arena refrigeration systems, bringing them out of the ice age and into the present day.
Beginning in 2019, arena refrigeration plant replacements and upgrades occurred at several facilities, including the Logan Boulet Arena, Enmax Centre, the Civic Ice Centre, the Labour Club Ice Centre and the Henderson Ice Centre.
Many of the projects included relocating refrigeration plant components from within buildings into purpose-built portable structures.
“This not only enhances safety by segregating the components, but the new plants also require far less ammonia refrigerant, with reductions ranging from 46 per cent to almost 96 per cent,” explains Facilities Engineer Muhammad Durrani.
The City says reducing the amount of ammonia to improve safety was a key objective of these projects. The new structures free up space within the facilities for other functional purposes, while the layouts allow for improved access for maintenance and operational personnel.
Modern technology is also allowing for more efficient oversight.
“The new automated control systems can be accessed remotely to streamline system controls and monitoring,” says HVAC and Controls Tech Mike Jensen. “We’ve also introduced redundant components that boost reliability and increase capacity for year-round programming.”
The new refrigeration plant rooms meet all safety code requirements, and site fencing and alarm systems are installed at each structure for enhanced security.
Facilities Planning and Projects Manager Sam Conard says when a municipality undertakes lifecycle replacement projects, the team often considers associated improvements that can be made to increase safety, efficiency, maintainability, accessibility and functionality. “These refrigeration plant upgrade projects are great examples of this comprehensive approach to project delivery.”
