This paper analyzes water surface evaporation principle and grasps essence of energy consumption in optimization design of water surface evaporator.It indicates that close degree with natural water decides different evaporator performance character,further analysis indicates E601 water surface evaporator can be taken as design basis of micro evaporator,and determines the technical point of water surface evaporator design.Taking the example of vacuum insulated cup,the design of hydrology,depth,accuracy,measurement and environment for the water surface evaporator are carried out.The computed result indicates that ME-1 micro evaporator may increase the existing evaporator precision 5 to 10 times,volume of ME-1 water surface evaporator can be reduced to no more than 2% of E601 water surface evaporator.The experiment proves that the depth of water surface evaporator should reach 60 cm,the micro water surface evaporator installed air bag is suitable for global environment,and the evaporate environment of ME-1 micro water surface evaporator is almost close to natural water based on irrigation theory.The conclusion believes that vacuum insulation technology is the central content of water surface evaporator design.Weighting method is the reliable way to increase measuring accuracy of water surface evaporator,and the isolation of evaporation and precipitation process can increase precision of water surface evaporator.
