China innovates with mist cooling system in Shanxi: reduces surface temperature by 5-8°C in minutes

• In an urbanization in Shanxi Province, northern China, an innovative fog cooling system has been implemented and is proving highly effective in combating high urban temperatures. The system reduces surface temperatures by 5 to 8°C in just minutes by generating a fine, artificial mist. The technology consists of a network of high-pressure nozzles that spray water in microdroplets, creating a mist that absorbs heat from the environment and cools the air and surrounding surfaces. According to local authorities, the system activates automatically when certain temperature and humidity thresholds are exceeded, allowing for efficient and energy-efficient climate control.

• This type of solution is being increasingly tested in China, a country facing increasingly intense heat waves due to climate change and rapid urbanization. Shanxi province, known for its heavy industry and hot summers, seeks to improve the quality of life for its residents and reduce energy consumption for air conditioning in buildings with this initiative. Urban climatology experts emphasize that mist cooling not only lowers the temperature but also improves relative humidity and can help mitigate the "heat island" effect typical of large cities. However, they warn that its use must be controlled to avoid excessive water consumption in water-stressed regions. So far, the first trials in Shanxi have been considered successful by local authorities, who plan to expand the system to other urbanizations and industrial areas in the province.
