Abstract:
The wet bulb temperature is an important meteorological parameter in heating, ventilation, power plant cooling towers and other many engineering designs. As automatic weather stations (AWS) are widely used in the meteorological station, the direct observation data of wetbulb temperature gradually stop, which gives difficulty in the engineering design parameters of wetbulb temperature in the weather analysis and the application. For the calculation of the wetbulb temperature at AWS, we employed the groundbased meteorological observation humidity formula and the basic idea of Newton’s iterative method, and obtained a simplified general iterative formula. An empirical formula of wetbulb temperature is used to calculate its initial value, and an EXECL spreadsheet is used to complete the iterative calculation of wetbulb temperature. The results show that, this calculation method of wetbulb temperature has high accuracy, less computation, as well as the calculation process simple and controllable. Therefore, it can be widely used in the wetbulb temperature calculation at AWS.
