max is the state of the water vapor in the air is called a saturated humid air and condensate (liquid or solid) is a natural equilibrium. Moist air as a mixture of dry air and water vapor is assumed to be composed of two components.The amount of air in the water vapor than zero (dry air) depending on the temperature and pressure ranges from a maximum value. dry air molar mass by the carbon-12 scale 28 965 kg / mol and a gas constant of the following values. Volumetric dry life of approximately 78 084% nitrogen, 20.9476% oxygen, 0.934% argon, 0.0314% carbon dioxide, 0.001818% Neon, 0.000524% helium 0.0007% methane, from 0% to 0.0001% sulfur dioxide, 0.0005% hydrogen and a total of 0.0002% Krypton, xenon is considered to consist of ozone gas. Components within the geographic regions, according to the altitude and very little time and can be changed. Of dry air with relative precision measurement has been shown as fixed. The dry air and water vapor in the atmospheric air is completely enclosed. In general, away from atmospheric air pollution sources included dirty smoke and gas. Various contaminated gas with a mixture of a plurality of atmospheric air gas and water vapor, pollen (pollen) and consists of smoke. Psychometric Dry and Moist Air Composition general observations in this section will be used as the ideal gas approximation. This error rate is decreasing with increasing pressure more. When using the ideal gas equation of 101 325 kPa and -50 to +50 ° C temperature heard from the air enthalpy and specific humidity in the error rate, at 0.7% which is smaller, it has been proven by Threkeld. Simplicity, speed and economy in terms of providing solutions with the ideal gas law used in air-conditioning problems if the comparison of the results of these formulas can be seen that the difference is negligible in order. It belongs to the humid air and water thermodynamic properties according to the new formula is presented in the tables in Annex 1 and Annex 2. Depending on the temperature and the studies conducted in recent years have found new correlations for thermodynamic properties. Psychometric, moist air using these properties and thermodynamic properties of moist air is a branch of thermodynamics dealing with procedures and conditions.
