Air conditioning: The secret of an indoor unit

The three main components that work together

At the heart of the indoor unit are three key components: a filter, a heat exchanger, and a crossflow fan. Each plays a different role, but they operate together as a system to create a comfortable indoor environment.

Filter: Removing dust from the air

As the unit draws in air, the filter removes dust and other particles, helping keep the air clean. Over time, dust can build up on the filter, making it harder for air to pass through. This restricts airflow and can reduce efficiency, causing the unit to use more energy.
Regular cleaning helps maintain smooth operation.

Heat Exchanger: Adjusting the temperature of the air

After passing through the filter, the air enters the heat exchanger, where its temperature is adjusted. Here, heat is transferred between the air and the internal system, allowing the air to be cooled or warmed as needed.
The heat exchanger is designed with thin aluminum fins that increase the surface area in contact with the air. This allows heat to be transferred more quickly and effectively.

Crossflow Fan: Distributing air efficiently throughout the room

Once the air has been adjusted, the crossflow fan sends it back into the room. It not only delivers air, but also circulates it throughout the space, helping create a more comfortable indoor environment. With its cylindrical shape, the fan creates an airflow that travels straight and reaches farther into the room while maintaining quiet operation.
