Automated controls for ice rinks cool down costs

After the control system was up and running for only six months, operators noticed a substantial decrease in run time of the compressors and brine pumps. While expressing initial concern that the equipment wasn’t running at night, TechCold explained that the system has the ability to float through low traffic times without any degradation in efficiency of energy usage. The Pro-Act system was set to maintain higher ice temperature during these times by way of the scheduling software allowing for operators to determine ice temperature set points based on the requirements of their facility. Depending on outdoor as well as indoor ambient temperatures, float times can be increased dramatically to reduce electrical loads and run times on equipment.

Jean Martin, operations manager at the centre, said he feels confident the system has resulted in substantial energy savings for the facility. He also noted that there are other associated energy savings with the Pro-Act upgrade in terms of the building’s heating requirements: “People have commented on the ambient temperature of the facility being more comfortable (warmer). This is a result of the refrigeration plant not running all night,” he commented.

With better management of the refrigeration system, the Tim Hortons 4-Ice Centre has created a more attractive venue for both skaters and their audiences.
