RH stands for Relative Humidity, which is the amount of water vapor present in air compared to the maximum amount that can be held at that temperature.
U-trap in HVAC unit drain piping prevents sewer gases from entering the building and maintains proper drainage flow.
Types of ducts include rectangular, round, oval, and spiral ducts.
Duct gauges are selected based on the size of the duct and the pressure it will be subjected to.
Y-strainers are used in HVAC systems to remove debris and particles from the fluid flow, typically installed before control valves or pumps.
