Header and Header Trench Construction
The purpose of the headers is to provide an ample quantity of secondary coolant to the cooling floor grid in an efficient manner. If the headers are too small there will be energy robbing pressure drop and the possibility of insufficient flow to meet the system requirements
Computer Control System
Most new recreational facilities utilize computer control for their various mechanical systems. The ice rink refrigeration equipment is no exception. Tremendous temperature control and energy efficiency can be obtained with modern computer systems.
Calcium Chloride versus Glycol
On an indirect refrigeration system a choice must be made between the type of secondary coolant that you select. Both Calcium Chloride and glycol have been successfully used over the years and there are applications where both secondary coolants have an advantage. To a much lesser degree other heat transfer mediums such as methyl alcohol have also been utilized in the ice rink industry.
