Carnot has agreed to pay Cimco $1.8 million to settle patent infringement suits stemming from CO2 refrigeration systems Carnot built for Quebec ice rinks
R744 technology innovator Systemes LMP has created a CO2 system for artificial cooling of ice slabs called the “CRYSTAL”, already installed at an ice arena in Canada. The CRYSTAL is a multi-compressor unit with an operating capacity of 30 to 140t ideal for new constructions of ice rinks under renovation. Thanks to its state-of-the-art design, the unit features total heat recovery of the compressors, which can be used for commercial space heating, hot water, mechanical room.
A motivation to transform industry perception of CO2 as a refrigerant was behind Hillphoenix’s decision to supply the first transcritical CO2 ice rink installation in the U.S.
