AbstractThis project is to study the temperature reduction by applying the principle of water evaporates. It has created a laboratory to study these principles and is divided into three cases is to reduce the temperature by using the principle of evaporation of water, the upper walls. To reduce the temperature by using the principle of evaporation of water, side walls on all four sides and reducing the temperature by using the principle of evaporation of water, the walls all aspects including the wall above. From the experiment can reduce the temperature in the laboratory has an average of approximately 4.8 oC during the day and can decrease the maximum temperature, oC 8 from the study showed that reducing the temperature of the wall four sides can reduce the temperature as high as possible, but the relative humidity is higher.
