What Does an HRV Do?
A Heat Recovery Ventilator (HRV) is a critical component of modern HVAC systems, designed to strike a delicate balance between indoor air quality and energy efficiency. HRVs play a pivotal role in ensuring that your home’s air is fresh and comfortable. Here’s how they work:
Air Exchange: HRVs perform a continuous exchange of indoor air with fresh outdoor air. This not only replenishes oxygen levels but also helps remove indoor pollutants like carbon dioxide, odors, and volatile organic compounds (VOCs).
Energy Recovery: In addition to providing fresh air, HRVs are engineered to recover heat from the outgoing indoor air during the winter. They transfer this heat to the incoming outdoor air, reducing the need for additional heating and, thus, energy costs. This process works in reverse during the summer to keep your home cool and comfortable.
What Is an HRV in a House?
In a residential setting, an HRV is a device integrated into the HVAC system. It consists of two separate air streams—one bringing fresh outdoor air in and the other exhausting stale indoor air out. These air streams pass through a heat exchanger where heat (or coolness in the summer) and humidity are transferred from one air stream to the other. This ensures a constant supply of fresh, pre-conditioned air while minimizing energy loss.
Should You Leave HRV On All the Time?
The optimal operation of your HRV depends on several factors, including your climate, indoor air quality objectives, and personal preferences. While some homeowners prefer continuous operation, others may opt for a more controlled approach.
Does My House Need an HRV System?
The need for an HRV system depends on various factors, such as your location, climate, home insulation, and ventilation requirements. However, here are some scenarios where an HRV is highly recommended:
