This device bring fresh, outside air into a home while simultaneously exhausting stale indoor air outside. In the process of doing this, an HRV removes heat from the exhaust air and transfer it to the incoming air, pre-heating it. This allows for the reclamation of much of the energy that otherwise would simply be vented outside. The end result.
Exchanges stale indoor air for fresh outdoor air with minimal heat loss. In winter, warmth from the indoor air being vented out is transferred to the outside air being drawn in.
HVAC equipment that saves energy by using a heat exchanger to transfer heat from the building exhaust air to the cold ventilation air entering the building.
A device that captures the heat from the exhaust air from a building and transfers it to the supply/fresh fresh air entering the building to preheat the air and increase overall heating efficiency.
A ventilator combining an air-to-air heat exchanger which transfers sensible heat between air streams with some combination of fans or blowers to provide fresh air into a building and exhaust air out of a building.
A device used in central ventilation systems to reduce the amount of heat that is lost as household air is replaced with outside air. As fresh air enters the house, it passes through a heat exchanger heated by the warm outgoing air stream and is preheated.
a heat exchanger designed to recover heat from air being exhausted from the home and transfer it to fresh air being supplied to the home. Typically 60–75 percent of the heat from the exhaust air is recovered and transferred to the fresh air supply (also see Air-to-air heat exchanger; Size, sizing).
Also known as an Air to Air Heat Exchanger, an HRV maintains high indoor air quality without excessive additional energy costs. It consists of two separate air handling systems - one collects and exhausts stale indoor air, and the other draws in fresh outdoor air and distributes it throughout the home.
