• Correcting ice-height differences caused by one-sided air distribution
• Reducing uneven cooling and condensation that affected playing conditions
• Precisely controlling ice-surface air velocity to at or below 0.2 m/s

Uneven ice height from one-sided airflow

Ducts along one wall directed air across the rink. Ice froze at different rates on the two sides, creating height differences that prevented normal play.

Unstable ice quality and condensation

Poor insulation and stagnant air near the spectator area caused water accumulation, reducing overall ice quality and wasting energy.

Limited redesign support for the existing imported system

The existing distributor could not promptly provide site-specific technical redesign. The system required redesign and reinstallation less than one year after its initial installation.

Central ducts with balanced discharge to both sides

Moving the ducts to the ceiling center distributed cool air uniformly to both sides. Indirect airflow avoided blowing directly onto the ice.

Low-velocity control at or below 0.2 m/s

Central distribution and indirect airflow provided balanced cooling while limiting air movement at the ice surface.

CFD-based site redesign

CFD verified direction, discharge volume, arrival velocity and return flow. The resulting site-specific pattern addressed uneven ice height and unstable ice quality.

Eliminating uneven ice height

Uniform temperature and air velocity throughout the rink removed persistent height differences and created a smooth ice surface.

Stable stone trajectories

Field measurements confirmed ice-surface velocity at or below 0.2 m/s, preventing airflow from interfering with stone movement and supporting precise shots.

Reduced noise and vibration

The fabric’s sound absorption created a quieter playing environment, helping players concentrate.
