ATMOsphere, publisher of R744.com, has announced six hydrocarbon-based case studies for the upcoming ATMOsphere (ATMO) Europe Summit 2022, taking place in person in Brussels, Belgium, November 15–16.
This year’s summit, the 12th edition of ATMO Europe, will be held at the Bedford Hotel & Congress Centre in the Brussels city center.
In addition to industry case studies covering hydrocarbons, CO2 (R744) and ammonia/NH3 (R717), the two-day program will cover end-user experiences, policy developments – particularly the EU F-gas Regulation and the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulation of PFAS – market updates on heat pumps, the health and environmental impact of f-gas refrigerants, training, SF6-free switchgear technologies, the ATMOsphere Natural Refrigerants Label, and the Cold Chain Innovation Hub (CCI-Hub) in the Philippines. There will also be networking drinks on the evening of November 15.
Those interested in attending the summit can register for tickets here.
Here is a summary of the hydrocarbon case studies, which mostly involve propane (R290):
Scroll compressor in R290 chiller for cold room application: Olivier Liégeois, Director Marketing Refrigeration, Emerson, and Matteo Bettoni, Project Manager Rivacold. This case study will explain the benefits of an R290 chiller, equipped with large scroll compressors, that serves medium-temperature cold rooms at a hotel in Southern Europe. The presentation will be focused on the advantages of an R290 scroll compressor, comparing it with other compressor types and refrigerants, and the benefits of a chiller system regarding safety, installation and maintenance. Start-up data will be provided from the first four months of operation running.
Energy efficiency in walk-in cold rooms through R290 inverter compressor technology: Marino Bassi, Key Account Senior Advisor, Commercial Business, Embraco, and Erik Venturi, EDC Commercial Refrigeration Design Section Manager, Daikin. This presentation will examine Daikin’s R290 Monoblock range, launched during Chillventa 2022, which uses Embraco’s variable-speed compressor technology. The system can be employed for refrigeration of walk-in cold rooms at food retailers and hotels, restaurants and cafes. The products offer several enhancements compared to the previous series, including low temperature/medium temperature operation, higher COP, improved capacity, energy saving, shorter pull-down, more efficient defrost and wide power supply input, says Daikin. The speakers will compare this system with one that uses a traditional on-off compressor and HFC refrigerants, including an overview of indirect emissions reduction through energy savings.
HVAC & Heat Pumps
Propane in heat pumps, a natural and sustainable solution with energy savings: Adrien Perez, General Director, CTA. This presentation will include case studies on customers who choose to install propane chillers. It will feature refrigeration applications at a food storage company and heat pump applications for offices or supermarkets. CTA will show energy and CO2e emissions savings for the life cycle of the installations thanks to high-efficiency components and smart control and supervision. Maintenance cost will also be analyzed in order to show the durability of the product and ease of maintenance.
Heat pump with R744 installation, a clever combination of CO2 transcritical with R290: Alessandro Farina, Application manager, Castel; Andrè Dunnebier, Partner, Eurocold; Wil van den Kerkhof, Technical Director Servex. In this case study, the installation is located at an industrial plant located in Massbree, the Netherlands.
the COP of the system is about 2.039 in cooling, but when R290 is used as a heat pump for hot water the COP increases to 2.5. Required water temperatures vary, but include 75C. The design features a transcritical CO2 unit, optimized with an R290 unit, though this adds complexity. All the heat extracted from the cooling system is brought into the heating system by the compressors. Because in this case heat is also required at a relatively high temperature, a transcritical CO2 system is used.
Transport & Mobile Air-Conditioning (MAC)
Field data review of a R290 transport refrigeration system in an electric fleet Dominik Radler, Chief technology Officer PBX. PBX made its R290 transport refrigeration system, ecos M24, commercially available earlier this year. In this presentation, one fleet will be analyzed to show the impact of the use of natural refrigerants like propane on the carbon footprint. Also, PBX will show a safe and simple transition from conventional fleets to zero-emission fleets.
The gap of the cold chain is finally closed: natural refrigerants in transport are viable: Dr. Ing. Jürgen Süß, Chief Technology Officer, Ecooltec. Ecooltec has released an electrically driven transport refrigeration unit for trucks, including semi-trailers and rigid vehicle bodies, that uses a small charge of hydrocarbon propene (R1270) as the primary refrigerant, together with CO2 (R744) in the secondary circuit. The primary objective is to offer customers in the temperature-controlled transport sector forward-looking, environmentally friendly technologies.
