In a three-year research study testing the viability of German manufacturer Liebherr’s CO2 (R744) air-conditioning system on a long-distance passenger train, the “eco2jet” project showed an energy efficiency improvement of 30%.
Functioning prototypes show how CO2 (R744) can be successfully used in applications such as bottle coolers, refrigerated containers and mobile air-conditioning without increasing costs or compromising on efficiency as compared to HFCs, according to Stefan Elbel, CEO of Creative Thermal Solutions (CTS), the Urbana, Illinois (U.S.), HVAC&R research company.
Carrier Transicold is to make lower GWP refrigerant R452A the standard gas for all new transport refrigeration units in North America from October.
Emerson announced its E360 Webinar series, “The Journey to Lower-GWP Refrigerants” will include five webinars designed to prepare food retailers and other industry stakeholders for the U.S. phasedown of hydrofluorocarbon (HFC) refrigerants. The series, which kicked off with the webinars “Regulatory Update: The Latest in Refrigerant Rulemaking and Safety Standards” and “The Role of Emerging Refrigerants Alternatives: CO2, A2Ls and R-290,” is designed to provide food retailers with strategies to achieve compliance of federal refrigerant mandates by exploring refrigerant and equipment options that align with their operational and sustainability goals.
Started accepting orders for commercial freezers using natural refrigerants.
A-Gas Managing Director – Europe, John Ormerod, explains why being inflexible about the use of high GWP HFC refrigerants in the short term may do more harm than good.
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.
Campaigners have called on European authorities to act on undercover investigation into illegal European sales of HFC published last year – citing a lack of action by national bodies.
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.
