Cleaning and replacing components like filters are common tasks needed to ensure an AC blower fan operates at its peak, circulating fresh air throughout your space effectively.
Types of blower fans
Centrifugal blowers are common in various HVAC systems. They use an impeller to increase the speed of air which then exits at a 90-degree angle. The design is similar to that of centrifugal pumps, making them highly efficient for moving air in a directed flow pattern.
These blowers work well in situations where there’s a need for rapid air exchange, such as in air conditioners and heaters.
Another main type is the positive-displacement blower. It traps pockets of air and pushes these volumes out against the system pressure, which is ideal for applications requiring steady airflow rates despite changes in the system pressure.
Tube-axial and propeller fans can also be categorised within blower types, each with unique blade designs suited to specific tasks like cooling electronic equipment or providing ventilation within confined spaces.
Each make and model may incorporate one of these fan types depending on its intended use and performance requirements.
The working principle of a blower wheel
A blower wheel sits at the heart of an air conditioning system, its blades meticulously designed to pull in air and then push it out with force. The motor powers up, initiating a spin that sets the fan blades into rapid motion.
This action generates a centrifugal force that effectively moves large volumes of air through the air-handling units. As it spins, the wheel draws in air from one side and accelerates it outward from the centre using centrifugal action within its slanted or curved blades.
This clever design ensures that your space receives a steady stream of cool, refreshing airflow during those warm days. Just like windmills harness wind power, blower wheels capture ambient air and amplify its movement efficiently throughout indoor environments.
Their constant rotation plays an essential role in maintaining comfortable temperatures and aiding indoor air quality by working seamlessly with other components such as heat exchangers and filters inside your AC unit.
