The refrigeration subassembly defines a primary closed loop engaging the extraction subassembly in heat exchanging relation. The enclosure encapsulates the refrigeration and extraction subassemblies. The quick-connect couplings extend outside of the enclosure. The extraction and refrigeration subassemblies are pre-wired and pre-plumbed inside of the enclosure. The electrical connector is accessible from outside the enclosure and connects the extraction and refrigeration subassemblies to the electrical source in single-phase AC relation. Coolant fluid circulates through the secondary closed loop, and refrigerant fluid circulates through the primary closed loop. The extraction subassembly extracts heat from the rink piping, and transfers heat to the primary closed loop. ...
