G0510405 Development of the Air Cooling Unit using Latent Heat of Water : 2nd report: the cooling performance and enthalpy

Abstract

To mitigate the CO_2 concentration, methods exist for the air-cooling using the evaporative latent heat of water for conservation of electric power. In this report, the temperature for cooling using the latent heat of water from a paste-moisturized test cloth on plates in duct was investigated. The enthalpy for air cooling was measured in the velocity range from 0.5 to 3 m/s and the relative humidity range from 20 to 65 %RH. As the result, the temperature of air decreases with increasing the velocity and relative humidity, and the enthalpy is unchanged.
