This document summarizes Mexico's first CO2 transcritical supermarket system installed at a Casa Ley store in Culiacan, Sinaloa, Mexico. The 75,400 square foot store uses a CO2 booster system with a gas cooler and compressor rack to power display cases. Compared to a traditional HFC system, the CO2 system was projected to use 6.8% less energy per year and have a 75% lower total emissions impact, though it requires a 47.4% larger refrigerant charge. The installation of high-pressure CO2 components presented some challenges, but maintenance costs were expected to be similar with additional cleaning of the gas cooler pads.

The document discusses gas cooler design considerations for CO2 refrigeration systems. It describes how using smaller diameter copper tubes of 5mm allows for more compact gas cooler designs that can withstand higher pressures of up to 130 bar. This reduces the internal volume and refrigerant charge compared to traditional designs. Case studies show how CO2 gas coolers using 5mm tubes can achieve equal or higher capacity compared to R404A designs, using fewer fans and a more compact footprint. The technology allows for more efficient gas cooler designs well-suited for transcritical CO2 refrigeration applications.Clare Perry, Environmental Investigation Agency (EIA)
The document discusses illegal trade of hydrofluorocarbons (HFCs) in the European Union and recommendations to strengthen enforcement of the EU F-Gas Regulation. It finds that over 16% of the EU's 2018 HFC quota was smuggled into the bloc, equivalent to 4 coal-fired power plants' worth of emissions. Common smuggling methods like mislabeling cylinders and using disposable cylinders are described. Weaknesses in customs enforcement like the lack of real-time quota data and exemptions for small shipments are also noted. The document recommends improving licensing, transparency, banning disposable cylinders, increasing penalties, and aligning the quota system with climate goals to curb illegal HFC trade and emissions.
