Brazil.
A renowned retail chain will open on October 27 a hypermarket equipped with a modern transcritical CO2 cooling system in the Brazilian city of Sao Paulo.
The system – in a 6,800m2 hypermarket in the Cambuci neighborhood of Sao Paulo – is the second transcrıtic CO2 facility in Brazil. The first was commissioned by the Carrefour Group for an Atacadão cash & carry brand store in Atibaia, State of São Paulo, which opened on June 16. Other systems run in test labs built by Bitzer and Eletrofrio, but Carrefour are the first in the field.
"We decided to import the technology. No one in Brazil is producing transcritical CO2 systems. Locally available components for these systems are also missing," Martini said.
Carrefour is determined to succeed there. Martini is convinced that the installation of transcritical CO2 systems in Brazil will help increase awareness of the performance benefits of the technology. "The process was smooth thanks to Plotter Racks, the system installer for both stores. We also have a maintenance contract with them," he said.
The Cambuci store is equipped with two reinforced transcritical co2 compression racks in parallel. Each rack has a capacity of 100 kW (at -8°C) for medium temperature users and a capacity of 45 kW (at -30°C) for low-temperature users.
The system's manufacturer, Advansor – which works with Plotter Racks in the Brazilian market – assembled the racks in Denmark before shipping them to Brazil. They also imported the heat exchangers (thermofin), while Danfoss provided the rack controllers. After the arrival of the Brazil racks, Plotter Racks assembled the gas coolers: adding its adiabatic system 'Breeze'.
Adiabatic technology restricts water consumption to the required amount, reducing the air inlet temperature of the gas cooler and thus improving the performance and reliability of the system.
