ENTHALPY ARITHMETIC DEVICE

摘要

PURPOSE:To simplify constitution and to calculate an enthalpy by obtaining the enthalpy directly from the temperature and relative humidity of wet air. CONSTITUTION:A relative humidity signal output part 1 outputs a voltage expressed by a linear function containing the relative humidity as a constant. A temperature signal output part 2 varies in amplification degree with resistance expressed by a linear function as a variable. A multiplier 3 finds the product of the temperature output signal and relative humidity output signal. An addition part 4 adds the output signal of the multiplier 3 to a constant signal to output an enthalpy value as a voltage value to an output part 5.
