IIR member news: Star Refrigeration chooses CO2 to cool down a beer warehouse
Star Refrigeration, collective member of the IIR, recently published a case study about a CO2 solution used to cool down a beer warehouse.
Alternative refrigerants to high-GWP HFCs
Intensification of international regulations on HFCs such as the Kigali Agreement or the European F-Gas Regulation leads refrigerant manufacturers to search for alternatives to high-GWP HFCs. Focus on some alternatives to R410A and R23.
A bill for HFC recovery in Japan
A bill submitted in January 2019 has just been approved by the Japanese government. It encourages HFC recovery.
Flammable refrigerants: the IEC approves the charge increase in commercial refrigeration
The International Electrotechnical Commission rejected in April a proposal to increase the charge limit of flammable refrigerants in the commercial refrigeration. But a recount has just reversed the decision.
Refrigeration technologies help preserve biodiversity
The role of refrigeration in biodiversity protection is illustrated by two examples: the cryopreservation of coral larvae and the use of refrigeration to fight bee colony collapse.
