How a Heat Recovery Ventilator Works

29_moy~v~Venmar_AVS_-_Constructo_1_0_HRVHeat recovery ventilation systems allow R-2000 homes to maintain high indoor air quality without excessive additional energy costs.

As shown in the diagram below, a heat recovery ventilator (HRV) consists of two separate air-handling systems – one collects and exhausts stale indoor air; the other draws in outdoor air and distributes it throughout the home.


The HRV system installed in an R-2000 home can change all the air in the house over a three-hour period. Most HRVs are also equipped with automatic humidity sensors that increase the ventilation rate when needed – for instance, when you use the shower. Exhaust air is normally collected from the kitchen and bathroom areas, where most moisture and odours are created.
