One of these natural refrigerants is carbon dioxide, or CO2, with the refrigerant designation R-744. CO2 is assigned to safety group A1 because it is neither toxic nor flammable. CO2 is also easily available and therefore cheap to procure. With a GWP of 1 and an ODP value of 0, the natural refrigerant CO2 (R-744) has no harmful effects on the earth’s atmosphere.
Benefits of the refrigerant CO2 (R-744):
The natural refrigerant CO2 is not suitable for every application. Other refrigerants are preferable for creating low-temperature heat, as they are more efficient in these operating conditions due to their thermodynamic properties.
Food production is one of the most sensitive industries. In this sector, heating supply requirements are particularly exacting. What reliable solutions does ENGIE Refrigeration provide to meet these requirements? The expert Frank Glaser, a key account manager for industrial and commercial heating at ENGIE Refrigeration, explains using the Osatina Group as an example.
What does the heat supply of the future look like? An interdisciplinary team at ENGIE Refrigeration has been focussing on this question for the past few months. The result: our new SPECTRUM Water heat pump, which has been available worldwide since 28 March 2022. Our employees explain the product characteristics and special benefits of this model in our ‘on point.’ magazine.
The redesigned QUANTUM Water from ENGIE Refrigeration has been available for about half a year. How is the model being received on the international market? And which properties do customers appreciate most? Our expert Daniel Keller, head of product and application management at ENGIE Refrigeration, shares his initial conclusions and talks about plans for the coming months.
Beethoven could never have imagined this: artificial intelligence (AI) has now completed his ‘unfinished’ 10th symphony. AI has already been used to complete compositions by Gustav Mahler and Franz Schubert. Applications involving artificial intelligence are finding their way into more and more parts of our lives – and providing entirely new opportunities. ENGIE Refrigeration is ready for the future: we asked our expert Jörn Stiegelmeier, head of technology and development, about the smart refrigeration and heating solutions our users can look forward to.
Demand for heating is increasing around the world: experts predict growth rates of around 5 per cent for the global market for local and district heat in the coming years. Conventional heat supplies based on fossil fuels were often chosen in the past, but heat pumps represent an investment in a sustainable future – for example, the thermeco2 high-temperature heat pump and the Spectrum heat pump from ENGIE Refrigeration.
Airports are the hubs of our globalised world. Refrigeration technology plays a key role in ensuring that processes run smoothly and visitors feel comfortable in the terminal buildings. In this interview our expert Bernd Heine, Head of Sales Support, explains what the aviation industry requires from chillers – and the sophisticated solutions that ENGIE Refrigeration provides for this business sector. In addition, he presents the best practices we have developed in our many years of experience.
From producing companies and data centres to hospitals and hotels: wherever companies use refrigeration on an industrial scale, they produce valuable waste heat. Anyone who utilises this waste heat saves energy, lowers operating costs and protects the environment – a real win-win-win situation. With its smart chillers with heat recovery, ENGIE Refrigeration assists businesses on their path to greater efficiency and sustainability.
If the required refrigeration capacity is not (or no longer) adequate during major events, winter amusements or seasonal peak demand, or if an important system fails, solutions must be produced quickly. However, permanent expansions to cover temporary refrigeration requirements involve additional investment costs and are only very rarely worthwhile.
The digitalisation of the economy is advancing in leaps and bounds, and it has not steered clear of the refrigeration sector. In this interview, our expert Senad Handanovic, head of MSR at ENGIE Refrigeration, explains the digital features of the redesigned QUANTUM Water – and the added value that these chillers therefore offer their users.
For which areas are applications with heat recovery suitable ? And how does this technology help operating companies lower their costs? Our expert Markus Enzensperger answers these questions in our interview.
