FAN COIL UNIT / AIR CONDITIONING

Features of Circular Cassette Type

Cooling and heating design that ensures even distribution of air flow
with constant spacing between the fan and coil

Circular Grille Type

Square Grille Type

Internal Airflow Analysis

• Velocity Distribution Specified: 0-10 m/s
• Result: Fluids drawn in by the circular cassette are forcibly driven by the
rotating fan, resulting in high flow rates due to the forced convection
device. The fluid exiting the fan undergoes deceleration due to the large
surface area before being discharged, causing an increase in flow rate.

Indoor Air Flow Analysis

• Initial Settings: 0-2 m from the ground → 20°C, 2-3 m →40°C
• Results: As the air conditioner operates, the internal flows are mixed,
resulting in a uniform temperature distribution overall. Over time, it can
be observed that the internal temperature gradually decreases.
The results above show the velocity distribution in the indoor space over
time.
High velocity is formed from the fan to the floor, and then the velocity
continues to circulate from the floor, spreading throughout the indoor
space.
