Enjoy and Value the Fresh Air! - H.D. Thoreau

What is Ventilation? “Providing for acceptable indoor air quality (IAQ) through the simultaneous exhaust of stale air and supply of fresh outdoor air.” In with the good! Out with the bad!

Why Ventilate?

Why Manage Humidity? Constant Temperature ( F) Moisture Prerequisites for Microbial Growth Source of Spores = = IAQ Solutions - HUMIDITY CONTROL

ASHRAE-recommended Comfort Problems Organic Growth Percent Relative Humidity, % RH HUMIDITY CONTROL

Why Ventilate?  Protect your families health.  Protect your home.  Provide a comfortable home environment.  Homeowners place high value on ventilation!

Contractors - Why Ventilate?  To reduce call-back problems  To make more money

Attributes of Good Ventilation  Ample installed air flow  Pressure balanced – both exhaust and fresh air blowers  Quite operation  Energy efficient  An engineered appliance

Attributes of Good Ventilation

Sound insulation No condensate drain ARI Certified zero exhaust air recapture Fixed Plate PLUS Sensible AND latent heat transfer No defrost control or heat required Good overall energy efficiency No moving parts RenewAire’s Answer Humidity control

ERVs verses HRVs  Heat Recovery Ventilators (HRVs) transfer temperature differential only   Aluminum and plastic plate exchangers and heat pipes   Good for high humidity and high temperature applications   Positive air stream separation   Not often used for general building ventilation because of low efficiency

Venmar Constructo 1.5 Complex hanging kit Condensate drain kit Re-circulation defrost damper shuts off OA and allows exhaust air back to the home Sensible transfer core or ERV at a substantial price adder

ERVs verses HRVs  Energy Recovery Ventilators (ERVs) transfer temperature and humidity differential   Desiccant wheels and enthalpic plate units   Best in cold climates and hot humid climates   High temperature and humidity transfer efficiency   Not used for indoor pools etc.

Air Flow balancing is not a problem for RenewAire!  Condensation and frosting does not occur which restricts air flow in the exhaust air stream.  Strong blowers mean trouble-free installations.  Differences in duct pressure have little effect on airflow rates.
