Daikin has recently been involved in the commissioning of three water-cooled R1234ze chiller units at CERN, the European Organisation for Nuclear Research and home of the Large Hadron Collider.

On May 11 the Kick Off workshop of the GCI III was held in Kenya. This session served to discuss with stakeholders the objectives of the new phase of the project, which aims to put Kenya at the forefront of green cooling technologies in East and Central Africa.

Scantec Refrigeration Technologies, an Australian industrial refrigeration system provider, installed a low-charge ammonia/NH₃ (R717) system to serve three high-rise freezer rooms at a Malaysian cold storage facility, achieving a specific energy consumption (SEC) more than seven times lower than that of the facility’s previous ammonia liquid-overfeed system.

Energy Partners Refrigeration (EPR), a South African cooling-as-a-service (CaaS) implementer, installed a 10MW (2,843TR) two-stage ammonia/NH₃ (R717) system at South Africa’s largest dairy company, Clover, in 2022, and the performance has so far exceeded forecasts.

A new group, the Coalition for Green Heating and Cooling, aims to persuade Italian and EU policymakers to pursue more aggressive measures in the upcoming revision of the F-gas Regulation, including support for natural refrigerants across HVAC&R sectors.

Water-cooled condensers that use evaporative heat rejection significantly reduce energy consumption compared to similarly sized systems utilizing either air-cooled or adiabatic heat rejection, according to an analysis by Steve Kline, Product Applications Manage for Baltimore Aircoil Company (BAC).

This summer’s heatwave in the UK has created havoc for many supermarkets with multiple stories of refrigeration system failures, lost stock and lost sales. All refrigeration technologies have been affected by this extreme weather, but now, with so many retailers using CO₂ systems, Daniel Clark owner and MD at Preston-based CO₂ systems manufacturer Isentra, asks whether 130bar transcritical systems have now become a necessity?

The U.S. General Service Administration (GSA), a government agency that supports other federal agencies, has shortlisted a CO₂ (R744)-based heat pump from Likido as one of nine “next-generation” building technologies.

EcoChill’s on-farm CO₂ cooling and water heating system for dairy farms could realize significant savings, presented Matthew Darby during ATMO APAC.

A study of two air-to-water reversible CO2 (R744) heat pumps with ejectors at a Swiss shopping center led to improved system performance at a subsequent installation, according to an article by Jonas Schönenberger, Head of Research and Development at Swiss engineering consultancy Frigo-Consulting.

Kaltra handed over a low-GWP chiller from its most innovative, ErP 2021 compliant Lightstream Screw II lineup to the client in the UK.

As the race to decarbonize gains momentum and interest in electric heat pumps builds, natural refrigerants, such as CO₂ (R744), ammonia/NH₃ (R717) and propane (R290), are key to long-term success and sustainability, according to clean energy expert Andy Baker, Owner and Project Manager at Seattle, Washington-based YourCleanEnergy.

A CO₂ air conditioning system from German manufacturer Liebherr has been successfully tested in a passenger train in Austria.

Transport refrigeration company Ecooltec Grosskopf has developed a new generation of electrically-driven transport refrigeration unit using CO₂ and the hydrocarbon refrigerant R1270 (propene).

The US Environmental Protection Agency (EPA) proposes to add a number of new lower GWP refrigerants to its SNAP list of acceptable substances for refrigeration and air conditioning applications.

By transitioning its lineup of commercial refrigerators and freezers to propane (R290), Georgia (U.S.)-based manufacturer Hoshizaki America has reduced the energy consumption of its equipment by an average of 11%, according to a recent presentation from the company’s Director of Engineering, David Sellers.

In a study coordinated by energy-efficiency-as-a-service (EeaaS) company Budderfly, two Subway restaurants in Connecticut (U.S.) realized average energy savings of 50% by installing U.S. manufacturer Refrigerated Solutions Group (RSG)’s new propane (R290) Capsule Pak ECO refrigeration system for indoor walk-in coolers and freezers.

Dutch supermarket chain Boon’s Markt, part of the Boon Food Group, has fitted its newest store in the village of Wolphaartsdijk with propane (R290)-based refrigeration display cases from Lithuanian manufacturer Freor.

“Awareness is very important” for the wider adoption of ammonia/NH₃ (R717)-based industrial refrigeration in Australia, said Stefan Jensen, Managing Director at Scantec Refrigeration Technologies, an Australian industrial refrigeration system provider.

A new Daikin refrigerant announced last year as a more efficient alternative to R1234yf in electric vehicles has been designated as R474A by ASHRAE and given an A2L classification.
