Résumé

Nocturnal cooling is an age old technique to cool the structure based on the radiative cooling to the night sky where heat loss by long-wave radiation from one surface to another body at a lower temperature. The nocturnal radiative cooling technique can also cool the water up to 28-30°C in a hot and humid place. This relatively cold water can effectively be used to pre-cool the air in a properly designed finned tube cooling coil unit. A test facility is developed where a finned tube cooling coil unit facilitates cool the air followed by conventional evaporative cooling. Results show that direct evaporative cooler clubbed with cooling coil to pre-cool the air attains the temperature drop of the order of 11°C, almost 4°C higher than conventional evaporative cooling with a batter control of humidity, in a hot and humid environment.
