I guess I'm OK with that, when I'm pushing up daisies.
"As the flowing liquid in the pipes cools the ice slab, it absorbs thermal energy to itself. This means
that the temperature of the liquid increases. As the liquid flows through the refrigeration unit, the
thermal energy is absorbed into the refrigerant and the temperature of the cooling liquid decreases.
The temperature difference between the supply and return temperatures of is known as the delta-t
(Δt) of the indirect cooling system. This difference Δt is typically 2-4 degrees Celsius/Kelvin.
Delta t (Δt) must always be also taken into account when measuring the surface temperature of ice.
If the measuring point is just above the supplying pipeline, the temperature of the ice is lower than
just above the returning pipeline. It is not possible to give just one measurement number as the
temperature of the ice. Therefore, the surface temperature of the ice varies within the rink, and the
temperature rules are always only guidelines within which the highest temperature and the lowest
temperature must be kept."
