‘People Are So Proud of This’: How River and Lake Water Is Cooling Buildings

“In the old days, it was like a more luxurious project,” the Dutch Energy Farm Leaded Deo Clark for a hot and cool solution to the encloso. Today, the clients of his company ask for the district heating system as well as the district cooling. ENECO has 33 heating and cooling projects under construction. In the Rotterdam, Netherlands, one of the organization’s establishment apartment block, police office, a theater and restaurants helps to cool the buildings, using the river water.

It is not difficult to see why cool technologies are becoming more popular. A few years ago, Naral moved from Paris. He remembers the heat wave. “My routine on the weekend was going to the parks,” she says. Nayral used to sit well in the evening – for reading ScrubbingNo less – his apartment is waiting for the cool. Recently, he has seen himself in the shopping malls, where it is abundant for air -condition control through a lot of hot French summer. This year, Heat wave Hit France and other countries in Europe.

Paris City is desperate to help its denigen now Find the cool refuges during the mantra of extreme heatThe The main component of the Parisian climate adaptation plan is the river -supplying cooling network, the pipes for which it currently covers a distance of 100 km, though it will extend up to 245 km by 2042. When about 800 is served by the building network, those who are in charge supply 3,000 buildings by their future date.

Systems like Paris do not pump river water around the property. Rather, a loop of pipework brings the river water to the benefits where it arouse warmth from the loop of a separate, closed water that is connected to the buildings. Heat exchanger is possible for the devices called heat transfer. Later, when the cool water comes to the buildings in a separate loop, more heat exchangers allows it to cool the liquid in the pipes that feed the air -conditioned devices in separate rooms. Basically, the heat, say, a packed conference room or tourist-filled art gallery is slowly popped by a river or lake pipe.

The efficiency of the Paris system varies throughout the year, but even when the sign is warmed at the height of the summer, the performance coefficient (COP)-many kilowatts that are consumed by system, when higher, when offices, museums, museums, museums, museums, museums, museums, museums, museums, museums, museums, museums, museums, museums, museums, museums, museums, museums. As it is. Air -conditioned system. “It’s absolutely great,” makes Nayral proud.

However, the temperature of that summer is gradually worrying. This summer, the sign briefly exceeds 27 degrees Celsius (81 degrees Fahrenheit), Nayral says. How could it make something cool? The answer is the chiller device, which helps to provide excess cooling for the water that performed around the building. Instead of blowing hot air, these devices can expel their heat through the river loop. The opportunity to continue is narrow, though – because Frechaur de Paris is not allowed to return the sign to the temperature at a temperature above 30 ° C for environmental reasons. Currently, this means that the river can adjust only a few additional degrees of heat in the hottest days. Future, strong heat waves can further evaporate of that overhead.
