Question

Which component

generates a
negative pressure of air going
in and a positive pressure of
air going out to transfer heat
to a space?
A. a gas valve
B. a blower wheel
C. a burner
D. a manifold

Answer 1

A blower wheel generates negative pressure of air going in and positive pressure of air going out to transfer heat to a space.

Step-by-step explanation:

The component that generates a negative pressure of air going in and a positive pressure of air going out to transfer heat to a space is a blower wheel. A blower wheel, also known as an impeller, is a fan-like component that creates airflow. It is commonly used in HVAC systems to circulate air and transfer heat. When the blower wheel rotates, it creates a negative pressure on one side, drawing air in, and a positive pressure on the other side, pushing air out. This airflow helps transfer heat to the space.
