Beijing, July 15 /Xinhua/ — Recently, in the city of Yuncheng, Shanxi Province in northern China, the air temperature rose above 37 degrees Celsius. An “artificial rain” system was launched on the roofs of one of the residential complexes. Ultrafine water sprays dispersed outdoors provide rapid and effective cooling in hot weather.
“Spraying ultrafine droplets of water from the building’s roof during a heatwave allows the surface temperature of the ground and air to be reduced by about 10 degrees Celsius in just a few minutes – it’s just like a scene from a movie!”
This month, videos demonstrating the operation of the high-pressure fogging system spread across social networks. The innovative cooling approach using such a system applied in Shanxi received numerous favorable reviews from foreign internet users.
In fact, this system was officially put into operation in Yuncheng city as early as August 2024. According to the residential complex developer, around 200 high-pressure nozzles were installed on the roofs of 7 high-rise buildings for each building. They spray water in the form of a fine mist. One spraying cycle lasts about 10 minutes. When the microdroplets evaporate, they absorb heat from the surrounding air, causing the temperature in the area around the complex to drop.
As reported by an employee of the management company of this complex, residents do not need to pay extra because all related expenses are already included in the fee for maintaining the courtyard area. Besides cooling, such mist-like moisture helps to settle urban dust and smog to the ground, while simultaneously humidifying the air and watering the greenery.
Let’s shift our gaze to the other side of China. Located in the southwest of the country, Chongqing is nicknamed the “furnace city” because of its scorching summer, but this summer you will feel cooler on the streets of this city than you might expect.
The thing is, a project called “Cooling Platforms” was recently launched in the city: air conditioners have now been installed at some bus stops in Chongqing, helping people cope with the effects of abnormal outdoor heat.
Just press the button, and a cooling mist immediately appears, instantly lowering the temperature in the waiting area by 3-8 degrees Celsius, while the energy consumption is only one tenth of that of traditional household air conditioners.
Let’s go down to the Chongqing metro, where in one train you can choose a carriage with one of two temperature options. In carriages with “strong cooling,” the temperature is set at 25 degrees Celsius, while in carriages with “weak cooling” it is set at 27 degrees Celsius. Clear signs on the platform help passengers choose what suits them best according to their needs.
In addition, rest areas equipped with benches and first aid kits have been set up at the metro stations.
In the central business district of Chongqing Jiangbeizui, where the Yangtze and Jialing Rivers merge, the “water-cooled air conditioning” system draws water from the rivers to remove heat from the indoor space. The heat exchange occurs without any loss of energy resources or environmental pollution, enabling the entire Jiangbeizui area to reduce carbon dioxide emissions by approximately 60,000 tons per year.
Towel: just moisten and wring out – the temperature immediately drops by 3 degrees Celsius; hip fan: completely frees your hands; umbrella with a sprayer: protects not only from the blazing sun but also from ultraviolet rays… In the city of Yiwu in Zhejiang province in eastern China, this summer creative miracle devices for fighting the heat are breaking export sales records, becoming genuine season hits.
From January to April of this year, the sales volume in the cross-border e-commerce sector in Yiwu reached 52 billion yuan, which is 17% more than in the same period last year. Heat protection and cooling products, thanks to their “lightness” and “practicality,” stimulate the “summer economy” worldwide.
Such creative high-tech cooling methods, like China’s “Artificial Rain from the Roof” and “Cooling Platforms,” can continuously bring new inspiration in the fight against heat and sweltering weather worldwide. -0-
