What does an Energy Recovery Ventilator do?
How Energy Recovery Ventilation Works. One of the benefits of using an ERV is that it transfers heat and moisture between incoming and outgoing airstreams. This means it takes much less energy to heat/cool the air you bring into your home, ultimately saving you money on heating and cooling costs.
What does Aprilaire ventilation controller do?
An Aprilaire ventilation control unit is designed to pull in outdoor air that is not too hot, cold, or humid to help reduce energy costs.
What is an ERV in a home?
Heat recovery ventilators (HRV) and energy recovery ventilators (ERV) are air exchange systems that help to enhance indoor air quality and minimize heating costs. They retain existing heat and optimize the interior moisture content in the air.
How do you size an Energy Recovery Ventilator?
ERVs/HRVs are typically sized to ventilate the whole house at a minimum of . 35 air changes per hour. To calculate minimum CFM requirements, simply take the square footage of the house (including basement) and multiply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by .
Does an ERV run all the time?
An ERV doesn’t need to. While the ERV contains a fan that’s less powerful than your HVAC fan, it’s still powerful enough to ventilate your entire home. The ERV fan can run all the time, providing more consistent ventilation. Efficiency: Compared to an HVAC blower fan, your ERV’s fan is less expensive to operate.
How does a fresh air ventilation system work?
Supply ventilation systems work in a manner exactly opposite of exhaust ventilation systems. Instead of pulling stale air out of the home, supply ventilation pushes fresh air into the home, which means that the interior air is subsequently pushed through the tiny pores and openings in the exterior walls.
Which is better HRV or ERV?
The best option between an HRV and an ERV depends on your climate and specific needs. If your house is too humid in winter (above 60% RH) then an HRV is the better choice, as it would surely get rid of excess humidity while an ERV would tend to keep it at a high level.
How does an Aprilaire energy recovery ventilator work?
In the summer, the ERV uses the stale, conditioned indoor air you’re expelling to cool the incoming hot air. In the winter, the ERV uses the stale, heated indoor air you’re expelling to preheat the incoming cold air. Learn more about the science behind the Aprilaire Energy Recovery Ventilator (ERV).
When did The Aprilaire Model 8100 Erv come out?
Aprilaire Model 8100 Energy Recovery Ventilator Systems manufactured in February 2012 or later may be controlled with the model 8910 Aprilaire Home Comfort Control , Model 8620 Thermostat, or by the Model 8120 Aprilaire Ventilation Control, allowing ventilation to occur on a schedule.
Why do you need an Aprilaire air conditioner?
Save energy by bringing in air when the outdoor air is just right. Push humid air outside by facilitating indoor air movement. Aprilaire’s ventilation systems help create healthy air in the home. By bringing in fresh air from the outside, we can dilute trapped airborne contaminants like allergens, chemicals, viruses and bacteria, and radon.
How does an energy recovery ventilation system work?
The heart of the ERV is the EnergyMax® Transfer Core, which uses enthalpic technology based on the second law of thermodynamics to enable the transfer of heat as well as moisture into and out of your home. In the summer, the ERV uses the stale, conditioned indoor air you’re expelling to cool the incoming hot air.
