Purpose and Learning Objectives. The purpose of this presentation is to provide industry professionals with an overview of the basic concepts and relationships between airflow and pressure, and how these concepts are affected by various outside factors in regard to fans.
A HVAC process flow diagram illustrates the step-by-step process of heating, ventilating, and air conditioning systems. It provides a visual representation of how air circulates, heat is transferred, and ventilation is controlled in a building.
Learn about the flow diagram of an HVAC (heating, ventilation, and air conditioning) system, including the movement of air, fluids, and energy through the different components and processes. Explore how the system works to provide comfort and indoor air quality in buildings.
Key Takeaways: A furnace air flow direction diagram shows how air flows through a furnace system. Arrows indicate the direction of the air flow, from the return air grille to the different areas of the home. The diagram helps identify potential obstructions or issues that may affect the air flow.
Furnace airflow direction is very easy to figure out with just 1 rule that applies to all furnaces and all filters. You don’t need to stick your hand into the air filter slit or anything like that. Nor do you need a furnace airflow direction diagram to figure this out.
Identify basic airflow concepts and science. Recognize the types of equipment and devices that are part of modern air distribution and ventila-tion systems for home and commercial applications. Identify the major sources of indoor air pollution and contamination.
The volumetric flow rate of air that will be conveyed through the duct in an air conditioning system is determined by the cooling/heat load and the desired supply air temperature.
