Overheating at Kirchplatz, Dusseldorf, with temperatures above 29 degrees Celsius recorded by Brumizer.
In the heart of Düsseldorf, a new cooling solution is being tested to combat the city's summer heatwaves. The Brumisateur, a prototype developed by the city's municipal utilities, is being put to the test on the church square until September.
Christoph Wagner, head of waterworks at Municipal Utilities Düsseldorf, explains the principle of the Brumisateur. When the temperature reaches 29 degrees Celsius, the Brumisateur activates 14 nozzles and sprays approximately 1.1 liters of water per minute, cooling the surrounding area through water evaporation.
The Brumisateur, standing at 2.5 meters high, 1.2 meters wide, and 60 centimeters deep, cools the nearby area within a five-meter radius by several degrees Celsius. This innovative cooling system is particularly effective in higher temperatures and lower relative humidity, making it an ideal solution for Düsseldorf's hot summer days.
The choice of the church square for the test operation is strategic. The square heats up significantly during a heatwave, making it an ideal location to test the Brumisateur's cooling capabilities. Jochen Kral, the city's mobility and environmental commissioner, expresses satisfaction about the new cooling option in the city.
While general knowledge suggests that evaporative coolers can lower the ambient temperature by several degrees Celsius, especially in dry and hot climates, the precise cooling effectiveness of the Brumisateur in Düsseldorf's urban environment cannot be confirmed without specific experimental data or reports.
Fortunately, residents and visitors of Düsseldorf will find plenty of drinking fountains to quench their thirst. Currently, there are 25 drinking fountains available throughout the city, with more planned in the future. An overview of the locations of the drinking fountains in Düsseldorf can be found here.
As the test operation of the Brumisateur continues, the city and its residents eagerly await the results. If successful, the Brumisateur could become a permanent fixture in Düsseldorf's fight against the summer heat.
In the context of the Brumisateur's testing for combating Düsseldorf's heatwaves, it's crucial to consider the role of environmental science. This innovative cooling system, through its principle of water evaporation, aligns with the fundamental concepts of science and climate-change research.
Moreover, if the Brumisateur proves successful in cooling the city, it could potentially revolutionize the field of environmental-science by providing a sustainable solution to urban heat challenges, leveraging technology to create a more comfortable living space.
