What is meant by Psychrometry?

Psychrometry is the study of the thermodynamics of gas-vapor mixtures. Psychrometry is the study of the properties of moist air and is useful to engineers concerned with heating, cooling, and ventilating buildings. Psychrometry is the subject which deals with the properties of gas-vapor mixtures.

What is Psychrometry in HVAC?

Psychrometric chart is one of the chart that is commonly used in solving HVAC problems. The properties of air such as wet bulb temperature, dry bulb temperature, dew point temperature, relative humidity, humidity ratio, specific enthalphy and specific volume are shown on this chart.

What is Psychrometry thermodynamics?

Psychrometrics (as distinct from psychometrics) is the study of the thermodynamic properties of air–vapour mixtures, typically focusing on the interrelation among temperature, partial pressures and enthalpy.

What is a psychrometric chart used for?

A psychrometric chart presents physical and thermal properties of moist air in a graphical form. It can be very helpful in troubleshooting and finding solutions to greenhouse or livestock building environmental problems.

What is Psychrometry Slideshare?

OIn other words, we can say that Psychrometry is the study of MOIST AIR or mixture of dry air and water vapour. PROPERTIES OF PSYCHROMETRY  DEW POINT TEMPERATURE  RELATIVE HUMIDITY  HUMIDITY RATIO  DRY-BULB TEMPERATURE  WET BULB TEMPERATURE  HUMIDITY • Specific humidity • Absolute humidity  PSYCHROMETRIC RATIO.

What is DBT and WBT?

Knowing both the dry-bulb temperature (DBT) and wet-bulb temperature (WBT), one can determine the relative humidity (RH) from the psychrometric chart appropriate to the air pressure.

Who uses psychrometric chart?

Psychrometric charts are complex graphs that can be used to assess the physical and thermodynamic properties of gas-vapour mixtures at a constant pressure. They are often used to assess the properties of moist air.

What is Psychrometry explain various Psychrometry properties and processes?

Psychrometry is the science of studying thermodynamic properties of moist air and the use of these to analyze humid air conditions and processes. Air conditioning processes can be determined with psychrometric charts and Mollier diagrams. Common properties in the charts includes. dry-bulb temperature.

What is a psychrometric calculator?

A psychrometric calculator is an engineering device used to calculate the properties of a gas-vapor mixture, and most often is employed to analyze water vapor in surrounding air.

What is psychrometry in RAC?

OWhen designing an air conditioning system, the temperature and moisture content of the air to be conditioned, and the same properties of the air needed to produce the desired air conditioning effect. OIn other words, we can say that Psychrometry is the study of MOIST AIR or mixture of dry air and water vapour.
