Energy recovery ventilator

A mechanical device that draws stale air from the house and transfers the heat or coolness in that air to the air being pulled into the house. This can help reduce energy costs and dilute indoor pollutants. Energy recovery units use the heat in the building to preheat in the winter or cool air in the building during summer to chill the incoming outside air. Ultimately, they use less fossil fuel by saving electricity to warm or cool the air; therefore, the air is cleaner because there is less fossil fuel burned to make the electricity. And the incoming outside air promotes better indoor air quality.An air-to-air heat exchanger or preconditioner designed to exchange temperature and moisture properties from one airstream to another. It captures the cooling or heating energy from the exhaust air before it leaves the building.

To reduce this energy use, air-to-air energy recovery ventilators have been incorporated for many decades into the design of HVAC systems.
A fully ducted heat recovery ventilator (HRV) or a fully ducted energy recovery ventilator (ERV) provides balanced ventilation independent of the packaged terminal heat pump (PTHP) conditioning system or, in the case of exceptionally efficient houses, independent of the heads of multi-split systems.
By correctly designing the system the latent energy added to the air from Biowall can be removed by the central HVAC unit, and with the model discussed, the Biowall will use the equivalent energy to that of an Energy Recovery Ventilator.
* Install a quality, energy-efficient, energy recovery ventilator (ERV) unit or heat recovery ventilator (HRV) unit to bring in clean, filtered outside air while also removing stale and contaminated inside air.

A house this tight could potentially have indoor air quality problems, but the builder will install an energy recovery ventilator that periodically brings fresh air into the house.
Five tests were conducted in each house, including: Baseline, Exhaust, Exhaust with mixing; Central-fan-integrated supply (CFIS) (Rudd 2011); and Energy Recovery Ventilator (ERV).
