Storage characteristics of wet air dehumidifier [2008-11-15] 
 Abstract: The humid air is dry air and water vapor mixture. Many industrial processes, such as air temperature and humidity adjustment process, the object of the drying process, water cooling towers in the cooling process, are related to the calculation of moist air. In the following sections: wet air, absolute humidity, saturated air, relative humidity, vapor pressure, dew point temperature, adiabatic saturation, adiabatic saturation temperature, moisture content, the enthalpy of moist air, moist air will be the nature of its calculation for an introduction. 
 To the gas mixture, the wet air is characterized by one-component - steam under certain conditions set state change will occur, that the steam condensed into a liquid or solid, or the reverse evaporation process. In order to simplify the problem, in the analysis, we make the following assumptions: 
 (1) the gas mixture as ideal gas mixtures, ie whether it is one of the dry air or water vapor, or mixture as a whole, calculated according to the nature of an ideal gas; 
 (2) When the vapor condenses into liquid or solid phase, liquid or solid phase does not contain dissolved air; 
 (3) the presence of air, steam does not affect their equilibrium between the condensed phase. In other words, although the moist air in the steam pressure (for which the partial pressure in the mixture) and the condensed phase pressure (total pressure for the mixture) is not the same, but the equilibrium temperature based upon the partial pressure of steam saturation temperature corresponding to the calculation. 
 The above assumptions, at high pressure may lead to large errors. However, experience in engineering and more moist air at atmospheric pressure or less pressure in this pressure range, according to the above assumes that treatment with sufficient accuracy. ★ ★ ★ (Galileo Galileo) machinery, equipment industry, high-end brands - the European Quality ★ ★ ★

 Describe the parameters of moist air (a) [2008-11-15] 
 Abstract: Wet air contains water vapor content and its status in which many industrial processes and are usually the calculation of moist air concerns. To this end, in addition to the general description of the parameters of the mixture, it also introduces some new parameters and describes the concept of moist air. Symbols in the various parameters indicated in the subscript "v" indicates that the parameter is water vapor, "a" that are dry air, "s" parameter that is saturated water vapor, without the amount of feet that are the subject of wet air . 
 Figure (7-1) in the vapor state of moist air 
 Pv and saturated air absolute humidity: humid air is the absolute humidity of moist air per unit volume of water vapor contained in the quality of it is water vapor density pv. pv determine the wet air temperature T and partial pressure of water vapor in the pv. Under the first assumption, according to the ideal gas state equation,

 Where Rg, v is the water vapor gas constant. Can be seen from the above equation,
