“People are very proud of this”: How is the waters of the river and the lake cool

“In the old days, it was more like a luxury project,” says Dio de Clelock, bullets in the Eneco Dutch company. Today, customers of his company are increasingly demanding the cooling of provinces as well as heating systems in the provinces. ENECO 33 has heating and cooling projects under construction. In Rotterdam, the Netherlands, one of the company’s facilities helps to cool buildings, including housing blocks, police offices, theater and restaurants, using water from the Music.

It is not difficult to know why cooling techniques have become more popular. A few years ago, Nayal moved from Paris. Remember heat waves. “My routine during the weekend was going to the gardens,” she says. Nayal was sitting there in the evening – reading Les MisérablesNo less – her apartment cools. Recently, she found herself spending time in shopping centers, where air conditioning is abundant, in order to achieve this through the hot French summer. this year , Unprecedented heat waves He hit France and other countries in Europe.

Paris is now desperate to help its residents Find cold shelters during severe heat attacks. One of the main components of the Parisian climate adaptation plans is the river refrigeration network, which currently covers the tubes 100 km, although this is due to 245 km by 2042. While about 800 buildings are offered by the network today, those officials aim to provide 3000 buildings by that next date.

Systems like Paris do not pump river water around the properties. Instead, a ring of river water pipes brings to facilities as it absorbs the warmth from a closed separate water ring connected to the buildings. This heat transfer is possible thanks to the devices called thermal exchanges. When the cooled water in the separate loop later arrives at the buildings, more thermal exchanges allow the liquid of fluid in the pipes that nourish the air conditioning devices in the individual rooms. Basically, the heat is transferred from a crowded conference hall or an art gallery filled with tourism gradually-by pipes-to a river or lake.

The efficiency of the Paris system differs throughout the year, but even at the height of the summer, when the Seine River is warm, the performance coefficient (COP)-a number of kilowatt hours of the cooling energy that you get in every kilowatt, hospitals still require some electricity, as they do not require much electricity in terms of phases, as they do not require much electricity, and exceed the number of electricity. Traditional air conditioning systems. “It is very cool”, “Nayral is proud.

But this summer temperatures are increasingly concerned. This summer, the Seine River briefly exceeded 27 ° C (81 degrees Fahrenheit), says Nayal. How can this cool anything? The answer is cooler devices, which help provide additional water cooling around the buildings. Instead of detonating the hot air, these devices can expel their heat in the Seine river through the river episode. The opportunity to continue doing this is narrowing, though – it is not allowed because Fraîcheur de Paris is not allowed to return water to the Seine River at temperatures of more than 30 ° C, for environmental reasons. Nowadays, this means that the river can absorb an additional a few degrees of heat in the hottest days. In the future, the strongest thermal waves can evaporate from that general expenditures.
