We are heading into the final workshop week at HVAC Technical Academy, and all are heavy with hands on action. Between brazing, component and system breakdowns, coil cleanings and getting to confident tool application, much has been going on.
Fundamentals
Air Traffic Manager: Plenum
There are two primary types: the supply plenum, which distributes air from the system to the home, and the return plenum, which pulls air from the home back into the system.
In a way, supply and return plenum acts as a “traffic manager” for air, ensuring consistent pressure and temperature regulation.
HACTA: I am a BRAZER
For those not familiar, HVAC brazing is a high-heat metal-joining process for creating strong, leak-proof refrigerant lines, using filler metal (like silver alloys) melted by a torch, requiring specific equipment (torch, rods, nitrogen) and strict safety protocols (PPE, fire prevention) to join copper pipes for high-pressure systems.
HVACTA: Plenum Progressing
When it comes to system swaps, proper air distribution is essential to air flow and cooling efficiency.
One of the many hands-on tasks at HVAC Technical Academy is constructing supply plenum.
HVACTA: It’s Brazing Time
The ability to braze effectively and safely is a requirement within the HVAC industry. Service technicians will be torching it up on a daily basis… recognizing the importance, HVAC Technical Academy insists all participants are above standard when it comes to brazing.
