As part of the community conservation programme of Belledune in Canada, its ice arena will be fitted with an ammonia de-super heater unit, which will capture the heat generated in the process of making ice to then use it to heat the water used to flood the ice.

The village of Belledune in Canada has now awarded the tender for fitting a new ammonia de-super heater at its Veterans' Memorial Arena, the ice arena available for pick up hockey and public skating, to Canadian based company Carmichael.

The ammonia De-Super heater

As described by the project management company Enerplan Consultants Ltd. the ammonia De-Super Heater unit “is a piece of equipment that gets tied into the ammonia gas piping that is used to make the ice. It works in much the same manner as a radiator in a car. The unit takes away some of the heat produced in the process of making ice, and uses it to heat the hot water used to flood the ice. The savings are achieved by reducing the electrical load required to heat the ice flood water. The ‘radiator' portion of this unit is submersed in the flood water to pre-heat it."

Belledune’s community conservation programme

The retrofit of the ice arena is part of Belldune’s community conservation programme, which was launched last year. Belledune has hence become one of the leading local communities in promoting energy efficiency and taking action on climate change. The programme targeted both homeowners and five municipal facilities for which energy audits were conducted with the help of Enerplan consultants.

Work is now ongoing to implement the recommended actions, which once complete will translate to expected energy savings of about $29,000 per year. Greenhouse gas emissions generated by the facilities are expected to decrease accordingly by about 167 tonnes.
