The virtual exhibition for sustainable cold chains aims to highlight the critical role of cold chains in ensuring food safety and security, access to vaccines, reducing global warming and preventing ozone layer depletion.
The exhibition showcases commercially available cold chain technologies for food and vaccines, mainly targeting applications and equipment with refrigeration and cooling cycles that use ozone and climate-friendly refrigerants and have enhanced energy efficiency characteristics. It also aims to promote game-changing and systemic approaches, relevant initiatives, and not-in-kind solutions to cold chains
These technologies and approaches directly contribute to meeting national obligations under the Montreal Protocol on Substances that Deplete the Ozone Layer including its Kigali Amendment and the Paris Agreement on Climate Change. Sustainable cold chain contributes to the achievement of many Sustainable Development Goals.
If you also want to demonstrate your sustainable cold chain technologies in this virtual exhibition to inform policy-makers, end-users and the public, this virtual place is for you.
The client – a large industrial kitchen supplying food to large companies – needed an energy-and-resource efficient solution for storing food products on site.
Since the customer is located near the Rhine River in Germany, they can use the groundwater to absorb excess heat and keep the condensation temperature of the chillers below the ambient temperature on warm summer days. The lower the condensation temperature, the higher the chillers' efficiency.
Secon supplies redundant air-cooled chillers to provide cold water to air conditioning units and to subcritical carbon dioxide units used for blast chilling and blast freezing of food. The redundant system ensures reliability of cooling capacity. The chillers use propane (R-290) as a refrigerant gas.
Thanks to this technology, the chillers can keep the outlet temperature at -8°C with low energy consumption. Their Seasonal Energy Performance Ratio (SERP) is more than 4 (i.e., over the year the cooling capacity is 4 times higher than the electrical power consumption).
