Grünenfelder uses Biaggini Frigoriferi system in place of R507A refrigeration system and reversible R404A heat pump.
The new CO2 system, which is the first for cold storage operator Grünenfelder, replaces an old troublesome R507A system.
The system was developed at the Center for Energy Technology (ZET) at the University of Bayreuth
In 2021, the Swiss manufacturer installed 10 new transcritical CO2 racks and its first two reversible CO2 chillers supplying both AC and heating for a Swiss mall.
The energy-efficient store includes a CO2 refrigeration system with permanent magnet motors, and cabinets with EC fans and LED lighting.
Scheduled for September 28-29, the event will take place, for the first time, both online and in-person in Brussels, Belgium.
Biaggini’s system is one of the first of its kind to use CO2 as the refrigerant in dual-duty air conditioning/heating system, the company said.
The system includes refrigeration, heating and air conditioning, and boasts up to 30% better energy efficiency than other CO2 booster systems.
Working with Biaggini Frigoriferi, the Swiss retailer has deployed a “total energy” system with provisions for refrigeration, heating and air-conditioning.
Biaggini Frigoriferi, situated in the Italian-speaking part of Switzerland, plans to install five integrated CO2 transcritical systems in 2019.
