    摘要: A method for determining the difference in enthalpy that occurs when a gas stream loaded with water vapor is cooled to a temperature below the dew point temperature, especially for determining its water vapor content (moisture measurement) is disclosed. The device preferably used to perform the method includes a gas cooler having an electrical cooling element and inlet and outlet ports through which a gas stream flows. Measuring devices are provided in the inlet and outlet ports to detect state parameters and through-flow values of the gas stream. The outputs from the measuring devices are evaluated by an evaluation device in connection with the electrical power draw of cooling element to determine the difference in enthalpy between the inlet and outlet ports and/or the water content of the gas stream.
