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.
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.
