Hvac Supply And Return Ducts

The needed airflows include for example supply air return air and exhaust air.

Hvac supply and return ducts.

They are easy to identify as they are the ones you feel the cool air coming from. It is important for the framer and hvac contractor to coordinate on the location of a return duct. Nearly all hvac systems are closed systems that rely on air circulation. You can easily spot your supply vents because they are the only ones you can feel conditioned air coming from.

This hvac floor plan sample shows the ventilation duct system layout. Supply vents are usually found high up on the walls in your home or on the ceiling. Ducts are conduits or passages used in heating ventilation and air conditioning to deliver and remove air. Remember arteries carry blood from the heart to the body whereas the veins carry blood from the body back to the heart.

The return vents in your home suck the air from your rooms into your return ducts and back to your heating and cooling system. Ducts commonly also deliver ventilation air as part of the supply air. The air is circulated over a gas burner heat exchanger for heating or an evaporative radiator for cooling. Planning sizing optimizing detailing and finding the pressure losses.

Ducts commonly also deliver ventilation air as part of the supply air. As such air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort. My house is hot or cold. They are typically larger in size than supply vents and you will not feel air blowing out of them.

This pulls the air across your body. If the supply ducts are high or in the ceiling then the return air ducts or grills should be low on a wall. Your return vents are typically larger than supply vents and you will not feel air being blown out of them. Static pressure in supply return ducts is important.

You can easily tell the purpose of a duct by which of these two types of vent covers it has. If installing supply ducts within the walls verify that the duct is capable of outputting the necessary air flow. Ducts are used in heating ventilation and air conditioning hvac to deliver and remove air. If your indoor air handler is the heart of the system the supply ducts are the arteries and the return ducts are the veins.

The needed airflows include for example supply air return air and exhaust air. A duct system is also called ductwork. An hvac system with proper air distribution has a ductwork design that incorporates a certain number of supply ducts for conditioned air delivery as well as return ducts to bring stale air back through the air handler to be reconditioned. If the supply ducts are in the floor then the return air should be located up high.

The air coming from these vents has traveled through your hvac system through the ducts and out of the supply vents. Cold air returns be more comfortable. This allows for proper spacing of the floor or roof structure for installation of the return. As such air ducts are one method of ensuring acceptable indoor air quality.
