Heat-recovery ventilator

Heat-recovery ventilator

A system that reclaims the heat from warm exhaust air exiting a building and uses it to preheat entering fresh air.

A heat-recovery ventilator (HRV) consists of a heat exchanger, one or more fans to move the air, and controls.
Civil<br />&nbsp;<br />Products Liability<br />Statute of Repose<br />Appellant manufactured the motor in a home's heat-recovery ventilator. Sixteen years after the ventilator was installed, a fire started in the ventilator and caused substantial property damage to the home.
Marsik, who teaches in the building, says students can measure the walls and calculate the expected R-value based on the insulation and also get into the crawlspace to see how the heat-recovery ventilator works.
Highlights of some of the homes built by Monkhouse include ah insulated concrete form foundation, triple-glazed windows, under-slab insulation, a heat-recovery ventilator, and solar-ready infrastructure.
Still, having the equivalent of a gaping hole isn't the best way to achieve that, so we discussed options for addressing the leakage without sacrificing fresh air: improve insulation; install a heat-recovery ventilator (which removes indoor air, takes fresh air from the outside, and filters it in); and install an air filter to take particles out without bringing fresh air in.
The miniHome (next page, middle right) sits on a 8-foot by 36-foot trailer chassis, and features SIPS (structural-insulated panel system) construction, a B100-Biodiesel powered cogenerating energy plant with optional solar and wind backup, a novel passive-HRV (heat-recovery ventilator), composting toilet, rainwater and greywater systems, LED-Halogen lights and computer-integrated controls, making the unit easy to operate and maintain.
The house also has a heat-recovery ventilator and a high-powered central vac.
For instance, you could install a heat-recovery ventilator ($ 1,000 and up) to bring in lots of fresh, dry air, without losing heat.
An energy-recovery ventilator is not the same as a heat-recovery ventilator. In an energy-recovery ventilator, the heat exchanger transfers a certain amount of water vapor- along with heat energy--to the incoming air.
The more high-end solution is to put in a heat-recovery ventilator. Those bring in fresh air, pre-warm it with the outgoing stale air, and so you have this energy exchange of that air that's being exhausted out of the house, recovering some of that energy from the cold air coming into the house, providing fresh air for the house, filtering it."
* A heat-recovery ventilator mixes outside air with captured heat or cool air, so fresh air is provided without compromising energy efficiency.
So, in addition to caulking all joints and wrapping the shell with house wrap, EQC specified a heat-recovery ventilator, which exhausts indoor air and brings in and dehumidifies fresh air from the outside.
