DEKI ELECTRONICS COOLING INSTALLATIONAwarded UN Environment Sustainability Grant
in collaboration with Ant Studio
A sustainable and inexpensive alternative old method of Evaporative cooling is used to provide a low energy and effective solution. The passive air cooler designed to cut the hot airflow in the passage by the generator.
The design was inspired by the structure of a beehive, using environment-friendly earthen cones to create an aesthetic prototype. The design and size of the conical components were customized through advanced computational analysis and modern calibration techniques. The thickness and the length of the material were modified with CFD analysis. The geometry of the pots and the stacked form provided a larger surface area for cooling while also ensuring that the air does not bounce back to the Genset. This was achieved by aligning the stacking of the pots to the airflow.
Excessive heat released from the Genset at the entrance in the external area of the factory had reduced productivity to a minimum. It was also heating the entire driveway making the exterior envelope of the building hotter, hence reducing its efficiency and increasing the air conditioning load of the building.
A sustainable and inexpensive alternative was required, and the team used the old method of Evaporative cooling to provide a low energy and effective solution. This technique, tracing back to the Egyptian period, cools down surroundings with the help of water and local materials. The thrust of hot air facilitates the cooling when used as a fan mechanism. Evaporative cooling needs air force. This design uses the air velocity from the Genset to its advantage.
The temperature drops by 6-8 degrees around the installation when the atmospheric temperature is above 40 degrees. Overall the temperature drops from almost 50 degrees. While recycled water might need regular maintenance to clean the pores on the exterior surface, regular water is recommended for long term performance.
