adiabate Kühlung im urbanen Raum
Description
This design offers an innovative solution to combat urban heat islands by using rainwater as a resource for a cooling system. At the core of the system is an underground cistern that stores rainwater and simultaneously serves as the starting point for adiabatic cooling.
Warm ambient air is drawn in, passed through cooling honeycombs inside the cistern, and cooled air is released back to the surface. Additionally, water mist nozzles generate a fine spray of water mist to cool the surroundings through evaporative cooling.
The modular cooling units are flexible and can be integrated into a variety of urban contexts. Using rainwater makes the concept resource-efficient and sustainable, as it saves drinking water and relies on natural processes.
The goal of the design is to improve the quality of stay in urban spaces and make both lingering and passing through more comfortable during hot summer months.
