Arenas > Reduced Flood Water Temperature

Existing Conditions

Flooding the ice typically accounts for 12% of the ice surface refrigeration requirements. When the flood water temperature is too high, the following problems and inefficiencies will occur:

•	The boiler will use more fuel to attain the higher temperature. It will also operate at a lower efficiency.

•	The ice surface will pond, taking a longer time to freeze.

•	The refrigeration equipment will use more energy to freeze the water.

•	If the flood water also supplies the domestic hot water, there can be a risk of scalding in the showers.

The DHW and flood water temperature is presently maintained at xxx°F by the DHW heating aquastat.

Retrofit Conditions

It is recommended that a fixed aquastat be installed to control the water temperature to 120°F. Experiment with lower temperatures to find the lowest flood water temperature that can be used without affecting ice quality.
