Meaning of term throw in a ventilation system?

Answer 1

In a ventilation system, "throw" refers to the distance that air travels horizontally from the point of discharge, such as a diffuser or grille, before it begins to mix with the surrounding air. It is a critical parameter that helps determine how effectively conditioned air is distributed throughout a space. Proper throw ensures even temperature and air quality, preventing areas of stagnation or draft. Understanding throw can aid in the design of efficient HVAC systems to optimize comfort and energy use.
