Yes. You will have to line the area with duct board or caulk all cracks and seal all holes at least. It can be used as a return, not cold air. Make sure there is no gas pipe running thru the area.
what about to use the space for running warm air?
The space between the floor joists may be used as part of the return duct system. This is an appropriate use for space that cannot be used for actual heating and air conditioning.
The AC duct's are in multiple places in the home. The main duct would be on the main floor where the air conditioning can keep everything cooler. The duct is located on the floor in the main part of the house.
If the duct tape is just taped on the floor, just carefully remove the tape. Using the edge of a knife helps lift it off the floor to start with.
Plenum rated cabling is required when used in an open ceiling return air environment. That is when the return air for the hvac units use the space between the ceiling of the first floor and the floor of the second floor as a return air plenum. The way to tell is if the return air vent has a duct attached to it. The duct will run to the air conditioning air handler. This condition IS NOT a plenum rated ceiling. However, if the return air vent does not have a duct, that means the air conditioning air handler is using the air space between floors as a plenum. This condition requires the use of plenum rated cabling. If plenum rated cable is exposed to flame, it does not give off toxic gases as it melts.
Before you make a decision if you should get your air ducts cleaned, you require knowing a little about how they work and why they collect dirt. You can simply tell the difference between return and supply ducting by going down to your basement and inspecting the sheet metal ducting typically found hanging from the floor joists on the ceiling. The return duct is typically a large rectangle that is attached to the bottom of your heating system, while the supply duct comes out the top of the furnace. The supply duct is usually made up of a large "trunk" duct on the ceiling, along with smaller metal ducts that branch off into each heated room. You'll find them often covered by a metal grate on the floor or the wall.
A Calot's triangle is an anatomic space bordered by the common hepatic duct, the cystic duct, and the inferior edge of the liver.
The supply duct system
Yes you could bt I wouldn't reccommend it because it will leave stickies on the floor.
add an in duct fan to boot the flow to the register , it will rob air from other areas, and you need to get/have access to the supplying duct to that register
Try looking where the return air duct connects to the furnace, if not there the next place to look is in the return air grille in the living space. Either way it is somewhere in the return air duct between the grille and the furnace.
The cystic duct lies between the gallbladder and the common bile duct. Its' function is to transport bile from the gall bladder to the common bile duct.
