Presentation Transcript

  • 1972 – First commercialization of cross flow fixed plate energy recovery ventilator

  • 1981 – Lawrence Berkley Labs identifies the advantages of ERV cores for residential ventilation

  • 1983 – RenewAire begins manufacturing ERVs in Madison, Wisconsin – other manufacturers follow with similar unit layouts



Field trials confirm breeze units install in one half to one third the time of traditional ervs
“Field trials confirm Breeze units install in one-half to one third the time of traditional ERVs.”


What is breeze
What is Breeze? one third the time of traditional ERVs.”

  • A line of residential ERVs

    • BR70 70 CFM ERV

    • BR130 130 CFM ERV

    • TW Kits Through-the-Wall duct and hood kit

  • Economical and effective ventilation for condominiums, town homes and smaller homes


A new line of residential erv
A New Line of Residential ERV one third the time of traditional ERVs.”


How is breeze different
How is Breeze Different? one third the time of traditional ERVs.”

  • Mounts to furnace (AC) return air ductwork

  • Has only two duct connections

    • The other two connections are out the back directly into the RA duct

  • Has integrated automatic proportional runtime control

  • Can be mounted to exterior wall with TW Kit requiring only two indoor duct connections


Two ways to install ervs
Two Ways to Install ERVs one third the time of traditional ERVs.”

  • Central Exhaust – Use EV Series

  • General Ventilation – Use BR Series

    • EV Series may be used


Central exhaust
Central Exhaust one third the time of traditional ERVs.”

  • 20 CFM continuous per bathroom

  • 50 CFM intermittent per bathroom

    • Must have control in each bathroom served (PB24)

  • Other possible exhaust locations

    • Kitchen area (cannot exhaust range hood)

    • Utility room, smoking room, hobby room, etc.


Ev130 centrally ducted
EV130 Centrally Ducted one third the time of traditional ERVs.”


Exhaust from bathroom
Exhaust From Bathroom one third the time of traditional ERVs.”


Exhaust from kitchen
Exhaust From Kitchen one third the time of traditional ERVs.”


Central exhaust con t
Central Exhaust one third the time of traditional ERVs.”Con’t

  • Small ductwork system to collect air from each exhaust location

  • Fresh air may be supplied to furnace (AC) return air duct

  • EV130=2 bathrooms, EV200=3 bathrooms, EV300=5 bathrooms

  • Replaces bathroom exhaust fans


General ventilation
General Ventilation one third the time of traditional ERVs.”

  • ERV selected based on size of home and/or number of residents

  • ASHRAE 62-1998 – 0.35 air changes/hour

    • BR70 = 1500 square feet living space

    • BR130/EV130 = 2700 square feet living space

    • EV200 = 4000 square feet living space

    • EV300 = 6000 square feet living space


General ventilation con t
General Ventilation one third the time of traditional ERVs.” Con’t

  • ERV selected based on size of home and/or number of residents

  • ASHRAE 62.2-2003

    • 7.5 CFM/occupant (# of bedrooms +1) Plus

    • 0.01 CFM/ square foot of living space

    • Example: 3 bedroom, 1500 sq ft home requires 4 times 7.5=30 CFM plus 1500 times 0.01=15CFM for a total of 45 CFM


General ventilation con t1
General Ventilation one third the time of traditional ERVs.” Con’t

  • Bathroom exhaust fans are also required

  • Air may be drawn from and supplied to the furnace (AC) return air duct as long as short circuiting is avoided (by running furnace blower)

  • The majority of ERV installations are used for General Ventilation most likely due to lower cost


one third the time of traditional ERVs.”Cut hole in Return Air Duct – bend flange in.• Mount hanging bracket on duct.


one third the time of traditional ERVs.”Mount Hinge Bar in proper location on unit.


one third the time of traditional ERVs.”Hang unit on duct.

• Wire Breeze to furnace control.


one third the time of traditional ERVs.”Swing Breeze into position and screw in place.


one third the time of traditional ERVs.”Locate Fresh Air Hood away from all exhausts.


one third the time of traditional ERVs.”Exhaust Hood location is not critical.


one third the time of traditional ERVs.”Installation is generally completed in under two hours!


one third the time of traditional ERVs.”Neat and Clean!


• Breeze can be mounted on Return Air drop. one third the time of traditional ERVs.”


• Hole cut. one third the time of traditional ERVs.”


• Hang and fasten unit to drop. one third the time of traditional ERVs.”


one third the time of traditional ERVs.”Alternate Return Air drop orientation.


Easy installation
Easy Installation one third the time of traditional ERVs.”

  • Mounted to furnace or AC return air ductwork

    • Under duct lengthwise

    • Under duct crosswise

    • Side of duct

    • On return drop (with some cautions)

  • Mounted to exterior wall with thru-the-wall kit

  • Mounted to ceiling to conceal two ducts


Tw kit
TW Kit one third the time of traditional ERVs.”


Tw installation
TW Installation one third the time of traditional ERVs.”


Effective efficient ventilation made easy
Effective, efficient ventilation… made easy! one third the time of traditional ERVs.”
