CONSTANT ENERGY CONSERVATIONemphasis and local building code changes over the past several years haveresulted in efforts to make buildings and homes more weather tight and draftfree. While these efforts have been successful, eliminating outside air leakagehas created another potential problem; air quality of the interior atmosphere.
Many provincial and local governmentshave become concerned that the relatively stagnant indoor air is showingincreasing levels of carbon monoxide and carbon dioxide. Many provinces haverequired periodic introduction of outdoor air into the indoor environment. The Dyna-FreshAir Quality Control Center coupledwith a model NSPRD024 or SPRD110 Spring-Return Damper was designed for thispurpose.
- Fresh air is drawn in from the outside and mixed with return air to be distributed by the air handling equipment.
- The Dyna-FreshAQC Control Panel coordinates the blower, exhaust fan and damper to introduce fresh air and remove stale air at user selectable 15 minute intervals.
- Stale air is exhausted by the independent exhaust fan.
