Sanden Europe is teaming up with distributor Bublshop to launch its CO₂ heat pumps in the UK.

The Customs and Excise division of the Ministry of Finance and Treasury, alongside the National Ozone Unit- Energy Division within the Ministry of Mines, Energy and Rural Electrification has seized imports of five cylinders of R12 gas.

A number of common refrigerants, including R134a, R410A and R407C, will be banned from use in new chillers in the USA from January 1, 2024.

A CO₂ industrial refrigeration system is key to the research and development work being carried out by Emerson at its Helix Innovation Center.

The EU’s ‘Winter Package’ of climate legislation, tabled yesterday, proposes to increase energy efficiency by 30% by 2030 in an effort to cut emissions and meet Europe’s obligations laid out in the Paris Agreement.

The North American Sustainable Retail Council (NASRC), together with U.S. member company DC Engineering, has published an online guide to transcritical CO₂ refrigeration systems.

Shortly after last month’s global agreement to phase down HFCs, Canada has tabled proposals to reduce its production and imports of these greenhouse gases.

In October, almost 200 nations agreed to an amendment of the Montreal Protocol that will see the emissions of hydrofluorocarbons (HFCs), a type of greenhouse gas used in fridges, air conditioning units and aerosols, phased out. This one action is expected to reduce global temperature rise by the end of the century by 0.5°C, a third of the 1.5°C cap agreed under the Paris Agreement.

In mobile air conditioners, the performance and environmental benefits of using R290 surpass R22, research has found.

The Ammonia Piping Handbook serves as a guide for the design and implementation of Colmac Coil’s DX ammonia refrigeration system.

A San Francisco store with the CO₂ technology will open in March.

The Italian company sees CO₂ systems becoming more affordable in emerging market economies with hot climates.

Climate change, greenhouse effect and global warming – scarcely any other issue is so omnipresent and so controversially discussed in the 21st century. Those who are convinced in doubting that climate change is man-made refer to various eras in the history of our planet where the earth has heated up or cooled down drastically even without any contribution on our part. In future too, they see climate change as the result of natural causes, including among others a changed ellipsoid orbit of the earth around the sun.

The decision as to which refrigerant should be used in a refrigerating or air-conditioning system is based on the major criteria of safety, costs and environment protection. But against the background of constantly increasing energy prices, the energy consumption of a system also plays an increasingly important role. Ideally, the chosen refrigerant should have excellent thermodynamic properties, high chemical stability and good physical characteristics. Furthermore, it should have no or only a negligible impact on the environment, while also being inexpensive and available worldwide.

The OEM has been especially busy this year, producing approximately 75 transcritical racks so far, including the new, smaller AdvansorFlex unit.

The container classroom responds to industry demand for training on CO₂ refrigeration systems.

The EEA is to report that the amount of HFC refrigerant placed on the market in 2015 – the first year of the phase-down mechanism – was within the quota allowance.

This report characterizes the current landscape and trends in the global A/C market, including discussion of both direct and indirect climate impacts, and potential global warming impacts from growing global A/C usage. The report also documents solutions that can help achieve international goals for energy efficiency and GHG emissions reductions. The solutions include pathways related to low-global warming potential (GWP) refrigerants, energy efficiency innovations, long-term R&D initiatives, and regulatory actions.

Russian retailer Magnit opened a new supermarket featuring a CO₂ transcritical refrigeration system manufactured and installed by NORD-SM with UNIDO technical support.

The book Refrigeration – Solved Examples is intended as a reference book for practicing engineers who would appreciate having a summary of useful formulae made available to them. It should serve as useful supplementary reading to students at various academic levels, lecturers and research workers.
