CHILLER FOR ICE RINK REFRIGERATION SYSTEMS

摘要

A chiller consisting of a tubular header for location alongside an ice rink and beneath the ice level. The chiller is divided into three vertically arranged longitudinal chambers having connectors for ice forming pipes which extend beneath the rink. Refrigerant conduction piping extends longitudinally through the chiller and connections are provided for a circulation pump to circulate the chilling medium within the header. The chilling medium being circulated through the header and ice forming pipes is chilled by heat exchange with the refrigerant carried by the refrigerant conduction piping from a refrigeration unit connected thereto.
