Describes an ASHRAE Award-winning design of a new four-pass brine system with evaporators in series, used to replace corroded header pipes in indoor ice rinks in Montreal. Illustrates the system schematically, which reduced brine flow by 50% and pump horsepower by 40%, while maintaining sufficient fluid velocity in the heat exchangers. Details the savings in electricity consumption for several rinks in tables, giving a cumulative saving for five rinks of $200,000 (Canadian).
