Daikin Airconditioning UK has launched two ground-breaking service packages, designed to guarantee the cost and supply of R410A refrigerant.

Signalling the growing market for ammonia-based refrigeration systems in Australia, Snowman exhibited its semi-hermetic ammonia compressors at ARBS 2018 where it saw significant interest in new technology from the Australian market.

All Delfield-brand refrigeration products will use hydrocarbon refrigerants by the end of this year, said Sara Sunderman-Kirby, product manager at Delfield, a division of Mount Pleasant, Mich.-based Welbilt.

A new report – Blowing It – by the Environmental Investigation Agency (EIA) reveals shocking evidence that the use of CFC11 in the polyurethane foam sector in China is the cause of the recently discovered increases in CFC11 in the atmosphere.

Star Refrigeration has brought an unused coldstore back to life with a system using lower GWP refrigerant R449A, advanced controls and innovative heat recovery.

Danfoss gas detectors are based on a digital platform that delivers multiple communication and integration options for improved operational reliability, easy calibration and maintenance efficiency, cost effectiveness, and regulatory compliance.

Signaling the growing market for ammonia-based refrigeration systems for industrial applications in Australia, U.S.-based Calibration Technologies Inc. (CTI) exhibited their ammonia gas sensors for the first time at ARBS 2018 this year.

The body representing European refrigerant manufacturers has urged European governments to ratify the Kigali Amendment to phase down HFCs.

A new paper from German compressor manufacturer GEA Refrigeration will be presented at a Sustainable Innovation in Refrigeration Air Conditioning and Heat pumps (SIRACH) Network meeting this Thursday (5 July 2018) on ammonia heat pumps in large district heating projects.

Representatives from 22 US conservative groups have signed a letter urging President Trump not to submit the Kigali Amendment to phase down HFCs to the Senate for ratification.

Last week the German Federal Environment Agency (UBA) warned that the degradation of HFO R1234yf – which is widely used in mobile air-conditioning systems – into trifluoroacetic acid (TFA; the atmospheric by-product of HFOs) could contaminate the water supply as the HFO cannot be removed after contamination has taken place.

Honeywell’s announcement of a new non-flammable, lower GWP alternative to R410A is perhaps seen as the answer to an air conditioning contractor’s prayer. But does it also create problems for the industry? Neil Everitt poses a few questions.

The attorney generals from eleven US states have filed suit against the EPA for “effectively rescinding” regulations prohibiting the use of HFC refrigerants.

Following more than two years in development, Isotherm, Arlington, Texas, has introduced a new version of its low-charge ammonia SX (shell-and-tube DX) evaporator, this time with an enhanced tube.

The leading US air conditioning contractors’ association has described the development of a non-flammable replacement for R410A as “welcome news” but warned that flammables training must continue.

Honeywell’s development of a non-flammable low GWP alternative to R410A has created huge interest, but what’s in it? The Cooling Post may have the answer.

Cold store rental company Dawsongroup says it has selected Chemours’ Opteon XL40 (R454A) as the alternative to R404A in its range of cold storage solutions for the European market.

Last month, scientists disclosed a global pollution mystery: a surprise rise in emissions of an outlawed industrial gas that destroys the atmosphere’s protective ozone layer.

Improved reliability, efficiency and safety herald a bright future for ammonia as a refrigerant as the low-charge trend takes hold, Andy Pearson of Star Refrigeration said on conference last week.

Refrigerant manufacturers Chemours and Honeywell and green group NRDC have petitioned the US Supreme Court to review the DC Circuit Court of Appeals decision to block EPA bans on HFCs.
