Abstract EN
An experimental study is conducted to cool the ambient air using a new humidification technique.
A wind tunnel is built with a test section formed by four modified MiniModule membrane contactors.
An ambient air passes over the membrane contactors (cross flow) while water pumps through the contactors.
Air temperature and relative humidity are measured upstream and downstream of the membrane contactors array which was used to humidify and cool the outdoor air.
Five average air velocities (3.03, 3.33, 3.95, 4.52, and 5.04 m/s) and four water flow rates (0.0, 0.013, 0.019, and 0.025 kg/s) are used.
Air velocity is measured at different locations along the centerline of the cross section.
Using the modified MiniModule membrane contactors array dropped the air temperature by a maximum and minimum of 10.77°C and 3.44°C, respectively, depending on the outdoor air.
The corresponding maximum increase of the relative humidity is 4.65% which depends on the ambient condition.
It is noticed that the evaporation process does not follow the isenthalpic lines therefore; heat transfers from the air as latent and sensible heats.
