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.
Many companies do not utilise their waste heat. This is a shame, as heat is required in a range of different processes, among them industrial production, building heating, and warm water supply. Far too often, companies use another method to generate the heat they require for these processes. And yet the waste heat gained from refrigeration, for example, can heat an entire housing block.
Heat recovery is a smarter solution, because it simply recycles waste heat. This is beneficial in several ways: using waste heat from the refrigeration process improves the overall efficiency of the chiller while reducing businesses’ energy costs. Refrigeration expert Markus Enzensperger, responsible for sales in the South/Munich region at ENGIE Refrigeration, explains: ‘Over the service life of a system, even minor energy savings can lower operating costs by several hundred thousand euros.’ Investments in additional heat generation systems can be reduced or even made entirely superfluous by heat recovery.
The environment benefits as well, because lower energy consumption has a positive effect on carbon emissions and thus on the ecological footprint of the businesses in question. ‘The actual reduction in CO2 depends on the proportion of heat recovered. In many cases, carbon emissions can be lowered by several thousand tons a year,’ says Markus Enzensperger. Companies can thus considerably improve the sustainability of their buildings and production chains. This is one of the reasons why there are attractive subsidies for heat recovery .
Heat recovery is worth it – especially for industries with a high demand for thermal energy. In line with its motto of ‘zero carbon transition as a service’, ENGIE Refrigeration assists companies on their path to climate neutrality with eco-friendly and perfectly efficient solutions. Our QUANTUM chillers are a perfect example. The innovative QUANTUM twin condenser technology allows heat to be discharged easily from the refrigeration process and then reused. ENGIE Refrigeration offers its air-cooled model series with what is known as green heat recovery (GHR). A special GHR condenser turns some or all of the waste heat into usable heat. There is another huge advantage: chillers from ENGIE Refrigeration can be deployed in a wide range of different industries – from production and business operations to data centres and hospitals
The CO2 high-temperature heat pump from ENGIE Refrigeration was chosen because it can supply the required network temperatures, retain a reserve for supply temperatures up to 90 °C, and can also be operated in parallel to a district heat supply.
ENGIE Refrigeration is taking over the refrigeration supply for the residential buildings in the Olympic Tower complex. For this purpose, four QUANTUM chillers with a cooling capacity of 1.29 MW each will be sent to Iran. These four machines will be used to set up a district cooling network within the building complex.
Environmentally friendly, renewable methods of energy generation are increasingly used to ensure an efficient heat supply to production facilities: the new production hall at the Mercedes-Benz plant in Rastatt is one such example.
Digitisation is one of the economic megatrends of our age. Most businesses are reliant on smooth-running information technology (IT) – and thus on data centres, the IT all-rounder. But how can a sensitive digital infrastructure be operated as safely, efficiently and sustainably as possible? With its QUANTUM chiller and SPECTRUM heat pump, ENGIE Refrigeration now takes care of ten local data centres belonging to a German provider – and is breaking new ground for the IT industry in the process.
Due to their environmental impact, refrigeration systems and heat pumps have faced increased scrutiny from environmental organisations, governments and the public for some time. Debate has centred on the greenhouse effect of refrigerants, not least because of planned amendments to the F-Gas Regulation, which will make it more stringent. However, the climate relevance of chillers and heat pumps can only be properly assessed with the help of an ecological balance sheet that includes the entire greenhouse effect of the systems. One popular method of holistic ecological assessment is provided by the TEWI value.
The digital transformation is opening up a wealth of new opportunities for companies. Augmented reality (AR) in particular is providing innovative momentum to Industry 4.0 and making complex processes significantly more efficient. ENGIE Refrigeration has long recognised the potential of this technology for the refrigeration and heating industry and has been working together with the global AR/VR technology leader HOLO-LIGHT since 2017 to integrate AR applications into individual work areas. Jannick Hartmann, Senior Software Sales Manager at HOLO-LIGHT, and Jörn Stiegelmeier, Head of Technology and Development at ENGIE Refrigeration, talk about the benefits of augmented reality for both employees and customers.
There are many chillers, but SPECTRUM Water only exists once. The model is unique in its performance range – this is ensured by the sophisticated product features. What precise added value does this offer to users?
The heating transition starts in buildings. This means that cities and municipalities, with their large number of buildings, play a crucial role on the path to carbon neutrality. What’s the best way to structure the energy transition and heating transition as soon as possible and as successfully as possible? Large heat pumps such as the SPECTRUM Water and thermeco2 can make an important contribution to this endeavour
Heat pumps instead of gas! At a state-of-the-art real-estate complex near the French metropolitan region of Bordeaux, a climate-neutral future is in the air, assisted by a new SPECTRUM Water from ENGIE Refrigeration. In our interview with Roman Steddin, the product manager explains why our heat pump is exactly the right choice for this project.
Anyone who has been in hospital knows that pleasant temperatures assist recovery. A clinic in Bavaria now provides such temperatures with a QUANTUM Water chiller from ENGIE Refrigeration, ensuring that the clinic runs smoothly.
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 Sales & Business development at ENGIE Refrigeration, shares his initial conclusions and talks about plans for the coming months.
