Zudek’s low-charge ammonia chiller at pharmaceutical site is 20% more efficient than HFC alternative
Italian manufacturer Zudek’s air-cooled, low-charge ammonia/NH3 (R717) chiller has improved the energy efficiency ratio (EER) of a cooling system at a pharmaceutical site in Belgium, by 20%, compared to its previous HFC-based unit.
Many causes of air pollution, such as vehicle emissions and industrial fumes, are more apparent outdoors, but air quality indoors can be equally poor. It can be a particularly acute problem in enclosed spaces like classrooms, with children being more vulnerable to the effects of pollution.
Mitsubishi Electric is to introduce a new room air conditioner in Japan which is said to automatically adjust to match your mood.
In a further move to adopt A2L technology, Danfoss has extended the cooling capacity range of its Optyma A2L condensing units and released A2L-ready hermetic filter driers.
On the 35th anniversary of the Montreal Protocol, it is fitting that you have returned to the city where it all began. Congratulations to all Parties and others involved for carrying out a repair job on a planetary scale. The ozone layer is now healing. Your work has delivered so many benefits, by both protecting the planet from UV radiation and slowing climate change.
Massive economic losses due to sweltering temperatures brought on by human-caused climate change are not just a problem for the distant future. A study in the journal Science Advances has found that more severe heat waves resulting from global warming have already cost the world economy trillions of dollars since the early 1990s—with the world’s poorest and lowest carbon-emitting nations suffering the most.
Entries are now being accepted for the ASHRAE and OzonAction of the UN Environment Programme (UNEP) 2022 Lower GWP Refrigeration & Air-Conditioning Innovation Award. The award promotes innovative design, research and practice by recognizing people who have developed or implemented innovative technological concepts applied in developing countries to minimize global warming potential (GWP) through refrigeration and air-conditioning applications. The award is part of the ASHRAE-UNEP OzonAction joint workplan for 2021-2023 under the global cooperation agreement established by both parties in 2007.
Carrier has extended the capacities of its flagship AquaForce Vision 30KAV liquid chiller range up to 1.3MW on low GWP refrigerant R1234ze.

ATMOspher has published a new report examining the reported evidence that HFO-1234yf, used widely as a refrigerant by itself and in blends, represents a growing threat to human health and the environment via its atmospheric degradation product, trifluoroacetic acid (TFA).
The extent to which minimising refrigerant leaks and maximising end-of-life recovery and reclamation can avoid fluorocarbon emissions in the USA is spelled out in a new report.
A custom-built Carrier MiniCO2OL rack, supplied in seven pieces, has been supplied to upgrade the refrigeration system at one of French retailer Monoprix’s premium stores in Montpellier.
A US team has developed what is claimed to be a first-of-its-kind tool that can calculate how much carbon dioxide buildings and homes produce.
The European Parliament’s environmental committee’s rapporteur has called for an outright ban on HFC and HFO refrigerants in most common uses and an even steeper phase down.
