Experimental Verification of Mist Cooling Effect in Front of Air-Conditioning Condenser Unit, Open Space, and Bus Stop

Mist spraying is a technique for locally lowering air temperature by fine mist into the and using latent heat of evaporation immediately after spraying. This study focuses on conditions under which contributes to increase in sensible release from human body, ratio decrease humidity space where sprayed. From measurement results front air-conditioning condenser unit, increased about 10 g/kg(DA), while decreased °C. an open park, 0.5 1 °C within 2 m spray g/kg(DA) at height spray, regardless distance spray. semi-open bus stops, slightly low-wind conditions. Unfortunately, measured relation increase, body perceives as cooler, were not available.
