Heat Pumps Installed at Bielenberg Arena

TRAK was subcontracted by Harris Mechanical to design a retrofit central plant using heat pumps and a 60 hole, 160’ deep bore field in lieu of a conventional refrigeration system. It was imperative to the City of Woodbury that the ice arena remain operational producing revenue and serving the community during the length of the project. Harris accomplished this by retrofitting the existing mechanical system to use a temporary ice chiller located outside the building while the existing equipment was being demolished and the new equipment was being installed. The entire mechanical room was also modelled in 3D by Harris and piping was prefabricated to minimize on-site construction time. Harris Companies provided guaranteed energy savings.
