“People are so proud of this”: How is the river and water of the lake cold buildings

“In the old days, it was more like a luxury project,” Peoples of De Klerk, a heating team and refrigeration solutions in the Dutch Energy company Eneco. Today, clients of his company are increasingly looking for cooling districts, as well as district heating systems. ENECO has 33 heating and cooling projects under construction. In Rotterdam, the Netherlands, one of the installations of the company helps refrigerators, including apartment blocks, police offices, theater and restaurants, using water from the Meuse River.

It is not difficult to see why colder technologies become more popular. A few years ago, Nairal moved from Paris. She remembers thermal waves. “My routine during the weekend was to go to the parks,” she says. Nairal would be woven in there in the evening reading MiserableNot less waiting for her apartment to cool. Recently, more and more finding time, time in shopping centers, where air conditioning is abundantly, in order to be done through the hot French summers. This year, unseen heat waves Hit the French and other countries in Europe.

The town of Paris is now desperate to help its demiries Find cool refuges during the spell extreme heat. The key component of paris climate adaptation is a river cooling network, pipes for which they currently cover a distance of 100 kilometers, although it should be expanded at 245 km to 2042. Years. While about 800 buildings, the network served today, they are in charge of supplying this future date.

Systems such as Paris “do not pump river water around the pipeline in the buildings, thanks to devices called the heat exchangers later to buildings, more heat exchangers allow the liquid to cool the liquids in the pipes that feed Air conditioners in individual rooms. In essence, heat, for example, the packaged conference room or tourist art gallery gradually transmit pipe pipe and on the river or lake.

The efficiency of the Paris system varies throughout the year, but at the level of flight, when it is a coefficient of electricity, when the offices, museums and hospitals still require small air conditioners, which still require small air conditioners, police officers still need a little Air conditioning. Systems. “It is absolutely magnificent,” can boast of the nairal.

But these summer temperatures are more worried. This summer, Sena briefly exceeded 27 degrees Celsius (81 degrees Fahrenheita), says Nairal. How can it be cool? The answer is the refrigerator, which help provide additional water cooling circulating around buildings. Instead of smoking hot air, those devices can expel heat in Sein over the river loop. The opportunity to continue to do this and, although Fraicheur de Paris is not allowed to return water to Sein at temperatures above 30 degrees Celsius, in the environment. Currently, this means that the river can accommodate only a few additional degrees of heat on the warmest days. The future, stronger heat waves could evaporate more of that regime.
