A British company specialized in ice rink cooling systems is using HFC-134a semi-hermetic compressors with variable speed operation for optimum energy efficiency.
The company claims their systems can halve cooling energy running costs compared with traditional refrigeration units, and is designed to deliver exceptionally reliable cooling and significantly reduced energy costs.
Reliability and efficiency are vital for ice rinks, and the system has to run 365 days a year, as it can take days for the ice to rebuild.
Several British ice rinks have already been equipped with such HFC-134a refrigeration systems.
