“In the past, it looked more like a luxury project,” said Deo de Klerk, team leader for heating and cooling solutions for the Dutch company Energy Eneco. Today, your business customers are increasingly requiring district cooling as well as district heating systems. Aeneco has 33 heating and cooling projects under construction. In Rotterdam, the Netherlands, one of the company’s facilities helps to cool buildings, including apartments, police offices, theater and a restaurant, using water from the Meuse river.
It is not difficult to see why cooling technologies become more popular. A few years August, Nayral left Paris. She remembers heat waves. “My routine during the weekend was to go to the parks,” she said. Nayral would sit well in events The miserableNo less – waiting for her apartment to cool down. Recently, she found herself to spend time in shopping centers, where the air convention is abundant, in order to spend burning French summers. This year, Unprecedented heat waves French France and other European countries.
The city of Paris is now desperate to help its inhabitants Find fresh refugees during extreme heat spells. A key element of the Parisian climate adaptation plans is the cooling network adapted to the river, whose pipes currently cover a distance of 100 kilometers, although two to extend at 245 km by 2042 3,000 buildings on this future date.
Systems such as Paris do not pump water from the river around properties. On the contrary, a piping loop brings water from the river to the installations where it soaks up the heat of a separate closed water loop which connects to the buildings. This heat transfer is possible thanks to the devices called heat exchangers. When the water cooled in separation later arrives later in the buildings, more heat exchangers catch it to cool the fluids in the pipes which feed the air control devices in the individual parts. Essentially, the heat of, say, a packaged conference room or an art gallery filled with tourists is gradually transferred – pipe by pipe – to a river or a lake.
The effectiveness of the Paris Vartes system throughout the year, but even at the height of summer, when the Seine is hot, the performance coefficient (COP) – how several kilowatt hours of cooling energy that you get for each kilowatt -hour of electricality consumed by the system – does not drop much below 4. Air conventional systems. “It’s absolutely magnificent”, boasts Nayral.
But these summer temperatures are in the event of concern. This summer, the Seine briefly exceeded 27 degrees Celsius (81 degrees Fahrenheit), explains Nayral. How can this cool spring? The answer is cooler devices, which help try to cool additional water circulating around the buildings. Instead of blowing hot air, these devices can expel their heat in the Seine via the river loop. However, the opportunity to continue to do this is to shrink – because freshness of Paris is not going to return the water to the Seine at Templere Ubove 30 degrees Celsius, for environmental reasons. Currently, this means that the river can only accommodate a few more degrees of heat on the hottest days. The stronger waves of heat, cound, evaporate more of these general costs.
