The report will aim to establish a clear relationship between ambient temperature and cooling effectiveness. In the initial phase of testing, the local ambient temperature was registered at approximately 26°C. However, it's worth noting that the temperature measured at the unit slightly exceeded this value, reaching approximately 31°C. 

This variance can be attributed to the inherent nature of the heat rejection unit itself, as it incidentally contributes to an elevated ambient temperature around the unit. The outcomes of the tests revealed highly encouraging findings, demonstrating that the EcoMESH system achieved an average cooling reduction of about 5°C. 

Importantly, the peak of the cooling effect showcased a DeltaT of 8°C across the mesh framework. These discoveries undeniably emphasise that the system's cooling capacity amplifies in direct correlation with the rise in ambient temperature.

The thermal image displayed below illustrates the distinctive shading advantage presented by the EcoMESH system when applied to vertical coil configurations. 

The photograph effectively demonstrates that, even prior to any water application onto the mesh, a substantial DeltaT of nearly 8°C is observed between the sun-exposed coil surface temperature and the surface temperature of our drift mesh. 

This DeltaT and the subsequent enhancement in efficiency represent a valuable passive cooling advantage that incurs no additional costs and functions seamlessly throughout the year, independent of water or electrical necessities.

This test showed that even at a low ambient temperature of 25°C, the unit's ambient working temperature was recorded at a peak of 28°C. The humidity was at 35%. 

The results showcased the EcoMESH system was still able to achieve a peak DeltaT of around 5°C, with an average DeltaT of 3°C across the mesh. In regular operating conditions there would generally be no requirement for adiabatic cooling at such low ambient conditions, however for the purposes of testing / data it was beneficial to show the true effectiveness of the system in achieving reliable cooling levels.
