Refrigeration Night
With the winter deep freeze upon us, what better time to talk about refrigeration.
This months presentation will be on the “Use of Transcritical CO2 in a Pumped Direct Floor Ice Rink” present by Brian Blahey. The presentation focused around a case study where this system has been installed in Bismarck, ND.
In an effort to employ green refrigerant options to the ice rink market and in response to pending restrictions and elimination of R-22 refrigerant production in early January 2020, CO2 along with ammonia are at the head of the class of low GWP and ODP refrigerant gases as replacements to the long list of man-made refrigerants in use today. By ultilizing CO2 as a primary “brine” refrigerant pumped directly into the refrigerated concrete slab, significant pumping horsepower savings are realized along with much higher system COP’s when return gas temperature depressed in cooler ambient conditions and overall on a seasonally adjustable basis. The case study in Bismarck, ND is a seasonal 9 month operation ice plant utilizing 6 semi-hermetic piston compressors, an adiabatic gas cooler and 1/2″ stainless steel tubes embedded in a 5″ concrete slab is a new option to existing R-22 flooded ice rink floor systems and new single pad rinks in both the retrofit and new construction market,
The presentation aims to identify:
• The primary difference between a typical primary (freon based) and secondary (glycol, brine) most commonly in use these days
• Explain the efficiency and environmental differences on a CO2 system
• Describe the construction pitfalls and advantages learned in Bismarck, ND
