Carrier is pleased to announce it has received awards from two well-respected and independent organizations. Carrier’s Dual-Stage Relief Economizer (DSRE) rooftop upgrade feature captured the 2017 AHR Expo® Innovation award in the Green Building category. The innovative DSRE also won the Silver Award for “Product of the Year” from Consulting-Specifying Engineer® magazine.
Carrier's DSRE is similar to a typical economizer with barometric relief but also integrates an additional relief plenum from the building space that bypasses the traditional barometric relief dampers. This patented design has two relief stages: the first stage of natural relief is through the new dedicated barometric relief plenum that provides relief when the building pressure warrants, regardless of the economizer damper positions or the indoor fan status. The second stage provides additional barometric relief through the traditional return air damper barometric relief path as the outdoor air dampers open further for free cooling. The DSRE uses no motors, fans or electricity to relieve building pressure and can help eliminate the need for electricity-consuming power exhaust fans.
