New IIR Informatory Note: Advancements in Supermarket Refrigeration
Discover the 37th IIR Informatory Note on “Advancements in Supermarket Refrigeration”
Conventional supermarket refrigeration systems are responsible for considerable CO2 emissions due to the direct effect of refrigerant leakage and the indirect effect of high energy consumption.
Energy consumption reductions can be obtained with advancements in refrigeration technologies that modify the refrigeration plant layout and components.
The new systems not only operate at higher efficiency, but also reduce refrigerant charge and refrigerant leakage.
In an attempt to reduce refrigerant emissions, modified systems with a lower refrigerant charge and groups of compressor racks located in fixtures throughout the supermarket have been introduced.
Other systems incorporate a secondary fluid, which is chilled by refrigeration machinery in a plant room separate from the retail area. Systems where each cabinet is equipped with its own compressor and a water-cooled condensing unit were recently developed.
The 37th IIR Informatory Note on “Advancements in Supermarket Refrigeration” considers the advantages and disadvantages of possible alternatives to the traditional solutions.
This IIR Informatory Note was prepared by Renato Lazzarin, President of IIR Section E and Yunting Ge, Vice-President of Commission E1, with the assistance of Claudio Zilio, Secretary of Commission B2.
It was reviewed by several experts from the IIR network.
