I am in zone 6 by the way.
Hvac attic dump zone.
In this scenario we send the extra air through a duct about 8 to 12 to a dump zone or another section of the house.
My attic ducts are insulated to what i believe is r 6 and the attic is currently insulated to r35 with blown in fiberglass.
My furnace and most of the duct is already in the conditioned space and it seems to be very complicated to bring the attic ducts back in the envelope.
If i am saving 37 a month at current energy rate.
Hvac zoning problems exist in forced air furnaces.
He is very thorough explains his work gives us simple tips for keeping our central air heating running smoothly throughout the year and does a.
Step 3 dump air to zones with lower set points.
I ll admit that was pretty scary installing that one.
I ve worked on crews that chose to dump the air into a living room and others that dumped it into the foyer with a 25 foot ceiling.
The cutting of waste.
An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan.
Roof and attic temperatures are higher than the outdoor air creating a greater.
Dump zone a room or rooms where the duct does not have a damper and will receive air flow any time the hvac system is running.
Managed dump zone use a bypass damper connected to dump duct into any or all zones.
When the 1st floor zone dampers shut i want to put a dump to get rid of the xtra 900 cfm s.
What i pay for air conditioning most months is less than 30 a month.
If the system determines that it cannot deliver the airflow into a zone that needs conditioning and that zone has an airflow limit selected the system will take the following 4 steps.
Adjust the bypass damper to stabilize the static pressure when the smallest zone only is calling.
Step 4 stage down equipment a.
Well mainly it s a way to save space.
The other is more comfort than you can imagine.
The rated efficiency of the unit.
Attic hvac systems save space.
In the same way imagine an airport with an hvac system.
Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.
Option 2 a dump zone.
The zone system pays for itself.
So why put an hvac system up in the attic at all.
All i can say is i would never consider anyone else.
Also it can be some interior area such as an underground store or a big attic where sunlight and heat cannot be easily reached and the natural temperature of the zone is already low.
The efficiency comes from 2 places.
I have part of my ductwork in my attic.
An airport is a massive open space with extreme variable occupancy and high difference in thermal loads.
Step 1 reduce airflow if possible.
Step 2 dump air to unoccupied zones.
10 of the time i run an additional zone.
