This Simple Diagram Shows You How Your Hvac System S Ductwork Connects It is responsible for distributing the conditioned air evenly and efficiently throughout your home, while also removing stale air and contaminants. a well designed duct system can improve your hvac performance, efficiency, comfort, and air quality. in this guide, we will show you how to design your duct system step by step. The plenum is basically a big box that holds air for the hvac system. it is connected to the various ducts and, oftentimes, you’ll have two plenums in your ductwork system: the supply plenum and the return plenum. the supply plenum gets filled with cooled or heated air by the hvac system, which is then ultimately sent through the ductwork.
This Simple Diagram Shows You How Your Hvac System S Vrogu So, if you like to learn the basic design skills including this duct design, consider enrolling in the course. it’ll give you a head start. 1. calculate the cfm for each room. most hvac units are designed to have a 400 cfm of airflow for every 12000 btu or 1 ton of cooling capacity and 12000 btu divided by 400 cfm is 30. In this hvac training video, i show and explain trunk duct fittings, elbows, dimensions, and names so that an apprentice or helper can learn the terminology. The main components of an air duct system. without getting too technical, ductwork is best described as a network of metal or flexible pipes that transport conditioned air from your hvac system to air vents, which then distribute the air into your home’s living areas. ducts typically snake through attics, crawlspaces, or basements. The zinc coating found in the metal hinders rust and helps you avoid painting costs. the metal ducts are lined using faced fiberglass blankets (also known as duct liner) or externally wrapped with duct wrap. if need be, a double walled duct can be used. aluminum – this ductwork is light and very easy to install.
