How can draw HVAC duct?

To draw HVAC ductwork, start by determining the layout of your duct system, including the main ducts, branches, and vents. Use a CAD software or graph paper to create a scaled plan, marking the dimensions and positions of each duct section. Draw straight lines for the main ducts and use appropriate symbols for fittings like elbows and transitions. Finally, label each section for clarity, ensuring that the airflow direction is indicated.

How does air handling unit work?

An air handling unit (AHU) is a crucial component of HVAC systems that conditions and circulates air. It works by drawing in outside air, filtering it to remove contaminants, and then either heating or cooling it to the desired temperature. The conditioned air is then distributed throughout the building via ductwork. Additionally, AHUs may include components like humidifiers and fans to maintain optimal indoor air quality and comfort.
