Scantec provides centralized low-charge ammonia system for poultry distribution warehouse in Western Australia

Scantec Refrigeration Technologies has provided a centralized low-charge ammonia/NH₃ (R717) refrigeration system for a new poultry warehouse near Perth, Australia, that it says offers an estimated annual energy savings of approximately 30% compared to “a conceptually identical liquid overfeed system.” Read more

Recommendations for 2040 targets to reach climate neutrality by 2050

The Commission is charting the path to reach the goal of making the European Union climate neutral by 2050. It recommends a 90% net greenhouse gas emissions reduction by 2040 compared to 1990 levels, which is in line with recent scientific advice and the EU’s commitments under the Paris Agreement.

Cool Talks: “We need to in­form, through dif­fe­rent chan­nels, that the­re are al­ter­na­ti­ves to F-ga­ses and that the­se al­ter­na­ti­ves are not dan­ge­rous”

For this Cool Talk, we have had the opportunity to interview Armin Hafner, Professor in refrigeration technology at the Norwegian University of Science and Technology (NTNU). In 1995 he joined SINTEF, in this capacity as researcher he worked closely with NTNU on CO₂, air conditioning and other refrigeration systems at that time. He became a professor at NTNU in 2016.

Study links three HFOs to super-pollutant R23 via ozone reaction in atmosphere

A new study has determined that three HFOs, including the widely used HFO-1234ze(E), react with ozone when they are released into the atmosphere to produce R23 (trifluoromethane), a powerful greenhouse gas with a 100-year GWP of 14,800 (IPCC, 4th edition). Read more
