A sling psychrometer requires manual operation to create the airflow over the bulbs, but a powered psychrometer includes a fan for this function. The psychrometric chart allows all the parameters of some moist air to be determined from any three independent parameters, one of which must be the pressure.

Occupants control their environment by means of clothing, operable windows, fans, personal heaters. Other formulations of thermodynamics psicromftrico in the following decades, statistical thermodynamics, or statistical mechanics, concerned itself with statistical predictions of carroer collective motion of particles from their microscopic behavior.

El diagrama de Mollier: Pressure Liquid water Avogadro’s law Nucleation Thermodynamic equilibrium. Psychrometrics, psychrometry, and hygrometry are names for the field of engineering concerned with the physical and thermodynamic properties of gas-vapor mixtures. The mass of water vapor per unit volume of air containing the water vapor.

The carta psicrometrica carrier chart is a visual representation of 3 components: This is the t —axis, the abscissa horizontal axis. Caarrier that use these materials are concerned with relative humidity control in production and storage of such materials.

Many substances are hygroscopicmeaning they attract water, usually in proportion to the relative humidity or above a critical relative humidity.


Psychrometrics – Wikipedia

Analogous to the specific enthalpy of a pure substance. In many industrial applications it is important to avoid condensation that would ruin product or cause corrosion. Molds and fungi can be controlled by keeping relative humidity low. This property of air-water vapor systems simplifies drying and cooling calculations often performed using psychrometic relationships.

The inner scale represents sensible-total heat ratio SHF. Humid heat is the constant-pressure specific heat of moist air, per unit mass of the dry air.

In psychrometrics, the term quantifies the total energy of both the dry air and water psixrometrico per kilogram doagrama dry air.


Temperature is important in all fields of science carta psicrometrica carrier carta psicrometrica carrier, geology, chemistry, atmospheric sciences, medicine. These lines are oblique lines that differ slightly from the enthalpy lines.

In industrial drying applications, such as drying paper, manufacturers usually try to achieve an optimum between low relative humidity, which increases the drying rate, and energy usage, which decreases as exhaust relative humidity increases. The “Mollier i – x ” Enthalpy – Humidity Mixing Ratio diagram, developed by Richard Mollier in[12] is an alternative psychrometric chart, preferred by many users in Scandinavia, Eastern Europe, and Russia. Chapter 2, Measurement of Temperature. The psychrometric chart quality is simply exquisite, combined with advanced psychrometric methodologies providing unmatched accuracy.

The psychrometric chart quality is simply exquisite, combined with carta psicrometrica carrier psychrometric methodologies providing unmatched accuracy. These charts focus on the carrirr of temperatures most suitable for comfort-cooling HVAC applications, and include the Trane coil curves, which depict the condition of the air leaving a cooling coil.

Operation of the psicrometrco is simple point and click, providing an easy-to-use program performing high level detailed process energy and psychrometric analysis. The psychrometric chart is also known as the Carta psicrometrica carrier diagram or enthalpy pressure psicdometrica. The dew point temperature is equal to the fully saturated dry bulb or wet bulb temperatures.


A chart is valid for a given air pressure or elevation above sea level. The thermodynamic wet-bulb temperature is a thermodynamic property of a mixture of air and water vapor.

The outer scale gives the ratio of enthalpy difference to humidity difference. Nobody Does it Better! They are also available in low and high temperature ranges and for different pressures. Knowing both the dry-bulb temperature DBT and wet-bulb temperature WBTone can determine the relative humidity RH from the psychrometric chart appropriate to the air pressure.

The term dry-bulb is customarily added to temperature to distinguish it from wet-bulb and dewpoint temperature. The accuracy of a simple wet-bulb thermometer depends on how fast air passes over the bulb and how well the thermometer is shielded from the radiant temperature of its surroundings.
