Tracing Heat for Freeze Protection of Fire Sprinkler Systems

摘要

For years, plumbing engineers have faced challenges when designing fire sprinkler systems in areas subject to freezing. Wet sprinklers are ideal for indoor areas or warm climates; however, when sprinkler systems were installed in areas subject to freezing, design optionsrnwere limited to dry, glycol and dry pendant systems. As the trend of integrating nature into our living spaces becomes more popular, complications arise when the installations include both indoor and freezing locations such as walkways, enclosed and open patios, glassed entries and balconies. Parking garages are another area of fire sprinkler design that present challenges to engineers. Tight spaces and potential exposed areas to the elements require complex sprinkler systems, thus more and more, plumbing engineers have to design sprinklers systems that are suited both for indoor and freezing locations.
