Sentences with phrase «incoming ventilation air»

Not exact matches

The heat recovery ventilation device recovers up to 90 % of the energy of the extract air to warm the incoming fresh air, saving on heating costs.

Unlike traditional, all - in - one HVAC systems that cool and recirculate indoor and outdoor air, displacement ventilation draws in only fresh air from the outdoors, and uses enthalpy - wheel energy recovery to cool the air slightly by transferring energy (heat) between incoming air and return air within the system's air handlers.

In addition, LEED for Homes awards two points to projects that go beyond basic ventilation measures and «install a system that provides heat transfer between the incoming outdoor air stream and the exhaust air stream.»
