5. ABSTRACT
Misting fan is similar to the traditional cooler which is used to cool the environment with
extra addition of fine water spray which is discharge through the pump. After running of fan with
high velocity the fine water spray sprinkle in front of fan with help of the nozzle toward the
direction of air flow.
Evaporative spray cooling systems can be used to provide thermal relief on hot days,
even in a subtropical climate. To characterize more directly the cooling effect of this particular
mist system, a dry silicone rubber skin analogue including embedded heat flux sensors was
heated to near-body temperature to measure the near-surface heat flux due to natural convection,
forced convection by the fan alone, and the fan and mist together.
It was found that the cooling effect of the mist and fan combination is highly efficient and
easily exceeds the thermal load of pedestrians, yielding nearly instant decreases in skin
temperature. Such outdoor technology has potential to reduce heat stress and discomfort,
particularly at large outdoor events and festivals. It could also reduce the required cooling loads
within individual buildings by providing inhabitants with thermal relief outdoors.
