REALice System
PNE Ice Arenas !PNE Currently has Two Ice Arenas in Operation ▪Coliseum (16,000 seating capacity and home of the Vancouver Giants from September to April) ▪Agrodome (3500 seating capacity and used for Community Ice from September to March)
!REALice Fortis BC Pilot Program (November 2013) REALice System was installed in the Agrodome instead of the Coliseum ▪Agrodome has 10 times more ice use than the Coliseum (more hot water floods with Zamboni and energy saving potential) ▪Agrodome hot water system could not keep up with shower water demand for user groups when Zamboni required hot water for ice floods (building was not originally designed as a Community Ice facility)
REALice System!Energy Demand for the Agrodome before the REALice System ▪Zamboni 520 has a 200 US Gallon tank (approx. 150 US gallons of hot water used per ice flood) ▪Zamboni averaged 12 ice floods/day or 2160 ice floods/year which equated to over 324,000 gallons of hot water previously used per year ▪Hot water for ice floods was previously between 120 and 140 degrees F ▪Ice temperature set point was 18 degrees F
REALice System!How Things Have Changed Using REALice ▪Community Ice User groups have requested less ice floods due to a more durable ice surface ▪Icemakers use only cold water for ice floods (45 degrees F) instead of hot water (120 to 140 degrees F) ▪Ice temperature set point increased to 21 degrees F (instead of 18 degrees F)
REALice System
Additional Advantages & Costs Savings due to Installation of REALice System !▪Ice System compressors have approximately 25% less run time ▪Hot Water Boilers have approximately 50% less run time ▪Community User Groups consistently have hot water for showers ▪Ice System Compressors and Hot Water Boilers have an increased life expectancy ▪Reduced Hydro and Natural Gas utility costs
REALice System
Transition Process and Starting to Work With REALice System !▪Ice specs and equipment run times were logged prior to REALice System being installed for future comparison purposes (December 2013) ▪PNE staff installed REALice System and monitoring equipment (December 2013) ▪“Old” ice was shaved out (approx. 1”) and REALice was installed between December 23 and 27, 2013 when no ice users were in the building ▪User groups commenced using REALice on January 2, 2014 ▪Ice Techs slowly decreased ice flood water temperature and increased ice temperature set points until optimum ice conditions were obtained ▪Ice Techs adjusted Zamboni speed during ice floods
REALice System
Perception from Stakeholders !▪Initial reaction from Ice Techs regarding the installation of REALice System was mixed ▪After REALice transition period Ice Techs are now convinced that REALice system makes a clearer and more durable ice surface ▪Ice Plant Operators immediately noticed less equipment run time ▪Management looking for ways to reduce energy use were very pleased with the results ▪Feedback from Community Ice user groups has been very positive commenting that the ice quality is excellent
