夏日的印度氣候一直高溫不斷，在人滿為患的現今狀態下，興建大型冷卻系統的方式，既不環保，也不能有效使用能源。在這種惡劣的環境下工作，對雇員的健康將會造成損害，這個問題也存在於 Deki Electronics 位在 Uttar Pradesh 的工廠。
The temperature during the day doesn't seem to stop rising in Indian summers, and installing big air conditioning systems is uneconomical and energy inefficient for a majority of the population. Working under such heated conditions takes a toll on the health of the employees, a problem which was also faced at the factory of Deki Electronics in Uttar Pradesh.

工廠外部入口處的發電機組，其放出的過量熱量使的生產率降到最低。它不僅加熱了整個車道，也使建築的外部結構更熱，從而降低其發電效率，並增加建築物空調的負荷。
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 up the entire driveway making the exterior envelope of the building hotter, hence reducing its efficiency and increasing air conditioning load of the building.

這樣的現況需要一個可永續使用且低廉的替代方案，Ant Studio 的團隊使用了傳統的蒸發冷卻法，作為低耗能且有效率的解決方案。關於這項技術，最早追溯到古埃及時期，埃及人將當地材料（Teasels／某種有刺的粗毛草本植物）浸水，使環境降溫。當通過風扇機構帶動時，熱空氣的推力有利於冷卻。由於蒸發冷卻需要空氣動力，這種設計使用搭配既有發電機組的風扇，顯現優勢。
A sustainable and inexpensive alternative was required, and the team at Ant Studio 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.

這個設計的靈感來自於蜂窩的結構，使用對環境友善的土錐來創建一個美觀的原型。通過先進的計算分析和現代化的校正技術，對錐形單元的尺寸和設計進行了定制。利用流體力學計算（Computational fluid dynamics／CFD）分析對材料的厚度和長度進行了修正。盆體的幾何形狀和堆積形式，為冷卻系統提供了更大的表面積，同時也確保了空氣不會回彈到發電機組。這樣的結果，是通過將盆的堆疊與氣流相互協調，來實現的。
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 air flow.

系統原型安裝在外部車道前進行了測試。安裝之後，空氣流動的溫度被儀器記錄下來。進入裝置的熱空氣在 50°C 以上，以 10 m/sec 的速度通過。系統所需要的水是從工廠回收，並維持在室溫之下，使用一只馬達就可以讓水在缸體表面流動。這樣的過程冷卻了通過陶罐的熱風。根據觀察，風在經過冷卻之後，溫度降低到 36°C ，而外界溫度是在 42°C 的高溫。當下的氣流速率為 4 m/sec。
The prototype was tested before being installed in the external driveway. The temperature of the air flow around the installation was recorded after it was set up. It was noticed that the hot air entering the installation was above 50 degrees Celsius at a velocity of 10m/sec. Water recycled from the factory at room temperature was allowed to run on the surface of the cylinders using a motor. This process cooled the hot air passing through the earthen pots. It was observed that after achieving the cooling effect, the temperature around the set up dropped down to 36 degrees Celsius while the temperature outside remained high at 42 degrees Celsius. The air flow was recorded as 4m/sec.

當氣溫超過 40°C 時，溫度會在安裝系統之後下降 6-8°C。總體溫度從近 50°C 下降。雖然水裝置的循環可能需要定期維修，以定期清潔陶罐表面的毛孔，如果需要更長期的使用，可以用常規供水以達到更好的性能。
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.

在印度，發電機系統通常放在街道建築的退縮區。由於電力供應不足，這些發電機組在一天中運行了一定的時間。這種低能耗和高經濟效益的解決方案，很容易在外部環境中建立並提供有效冷卻，尤其在炎熱和乾燥的環境中（如工業區室外）裝置。
In India, generator systems are usually placed in setback areas where loading and unloading takes place. Due to the shortage of electrical supply, these Gensets run for certain hours in a day. This low-energy and cost-efficient solution is easy to build and provides cooling in external environments, especially in industrial Outdoor set-ups in hot and dry climate.

這樣的系統也可以轉換為不須插電的方案，只需要手動澆水將盆罐淋濕。這樣就可以在電力供應不足的地區進行，雖然稱不上是一個理想的解決方案。
The installation can also be converted into a zero-energy prototype which would require manual pouring of water over the pots. This can be done in areas where there is shortage of power supply, but it is not an ideal solution.

這系統正在進行室內的安裝測試，評估是否可以在內部空間使用，以及如何適應室內環境。
Tests are being done to see if this installation can be used internally, and how it can be adapted to the indoor environment.
