Alternate Refrigeration Systems for Improving Ice Quality in NHL Arenas<\/strong><\/p>\n
The National Hockey League is a multibillion-dollar industry, and yet suffers from a recent uptick in complaints over sub-par ice quality, largely due to a warming climate and higher average ice rink temperatures. The objective of this paper is to demonstrate the superiority of an indirect ammonia\/CO2 refrigeration system over a direct CO2 system, all in relation to the current indirect ammonia\/brinewater system. The comparison will be made based on three criteria: efficiency, represented by the coefficient of performance value; cost, taking into account short- and long-term investments; and environmental effect, presented as a Global Warming Potential value. The results show that the indirect ammonia\/CO2 system is 56% more efficient than the current system, and 20% more than the direct CO2 system, and is less costly in the long-term. The environmental effects of each refrigerant systems were shown to be negligible. It is recommended that the NHL implement an indirect ammonia\/CO2 system in order to negate the warming arena temperatures, and ensure that the NHL remains a powerhouse in the sports industry.<\/p><\/blockquote>\n
