Professional Guide to make HVAC Ductwork Fabrication

 

Whether you are new to HVAC or working in the industry, this page contains many useful resources to enrich your wine knowledge. let's start!

What is HVAC?

The term HVAC (heating, ventilation and air conditioning) ductwork describes any ductwork and vent system used to direct and distribute air in a vehicle or structure. HVAC ductwork is used in a variety of spaces from automobiles to homes to the largest construction sites, but all systems share certain characteristics in that they provide air circulation. Duct systems can be made from a variety of materials, depending on the intended installation site and the characteristics of the HVAC system it is designed to serve. All HVAC ductwork should be properly sized, tightly sealed, and securely installed for safe and efficient operation.

HVAC ducts and insulation materials

In the ventilation project, the air duct should be made of suitable material according to the project requirements. Design and construction personnel need to fully understand the air ducts of different material properties and their use, application occasions, and under what circumstances the air ducts need to be insulated, to build a reasonable and durable ventilation pipe network system.

 

Therefore, having a certain knowledge of HVAC ducts and insulation materials will give you a better understanding of HVAC!

Grilles and Diffuser Production Machine

HVAC grilles and diffusers are the exit ventilation points for heating, ventilation and air conditioning (HVAC) systems. Although they are occasionally used as return vents, their primary purpose is to introduce conditioned air into the space so that it is evenly distributed and mixed with minimal noise. 


HVAC grilles and diffusers come in a variety of standard sizes, usually square, rectangular or round; they usually have a set of louvers or fins that direct airflow in a pre-set pattern. Larger industrial grilles and diffuser may include adjustable louvers or dampers that can be adjusted manually or automatically to control airflow.


Although diffusers are often seen as decorative grilles for inlet vents, they play a vital role in the effectiveness of HVAC systems and should be properly matched to any given application.
