Humidity in Ice Rinks
There are two sources of moisture in
an indoor ice rink: infiltration and
spectators. This moisture travels
from warm areas to cold areas, since
the colder surface has a lower vapor
pressure. In an ice rink, this move-
ment is predominantly toward the ice.
Some moisture will also move toward
the ceiling.
If the cold surface temperature is
below the dewpoint of the air, con-
densation will occur.
The visible effects of condensation
are fog near the ice surface, and
water droplets on the ceiling. In
extreme case, inverted icicles may
form on the ice surface.
Fog Near the Ice Surface
Fog is formed when moisture laden
air at the ice surface cools to or below
its dew-point temperature.
The ice surface actually acts as a
dehumidifier, freezing moisture from
the air onto the surface as additional
ice. This process increases the load
on the ice-making equipment and
wastes energy.
The ice surface, the boards, and the
spectator guards trap a pool of
moisture-laden air on top of the ice.
To remove the moisture without
melting the ice, units must be
properly installed in p
airs. (See
Installation.)
