A guide to ammonia in North American ice arenas
ATMOsphere announced the release of the “North American Guide to Natural Refrigerants in Ice Arenas,” including information on ammonia systems.
This 92-page guide provides arena owners and managers with information on why refrigeration systems using a natural refrigerant – CO2 or ammonia – are a better long-term choice from a business and environmental perspective than a system using an HFO blend like R513A or R449A.
HFO blends – consisting of an HFC and an HFO – represent a significant threat to the environment, the guide argues. Ammonia and CO2 are found in nature and, as refrigerants, are environmentally benign, as well as more efficient and less costly than HFO blends.
One of the arenas profiled in the guide is the Climate Pledge Arena, home to the NHL’s Seattle Kraken, which chose ammonia for a facility that is targeting net-zero-carbon certification by the International Living Future Institute (ILFI). Ammonia is one of the most common refrigerants used in ice arenas in North America, with thousands of successful installations.
The guide features successful installations of ammonia and CO2 ice rinks, as well as the history of natural refrigerants in ice arenas, the basics of using natural refrigerants, the efficiency advantages of natural refrigerants, regulations impacting these refrigerants and the environmental and health impact of HFO blend refrigerants.
