What is psychrometry in air conditioning?

Psychrometry is the study of moist air. It is significant in terms of thermal comfort and is a major consideration in design of air conditioning systems. Air conditioning engineers use the psychometric chart to predict changes in the environment when the amount of heat and/or water in the air changes.

What is psychrometry What do you mean by relative humidity?

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.

What is psychometry in refrigeration?

Psychrometry is the study related to the thermodynamic properties of wet air (mixture of dry air and water vapor), such as temperature, moisture, enthalpy and specific volume. All of those properties can be visualized and associated on the Psychrometric chart: PROPERTIES: Specific Volume.

What do you mean by psychrometry explain Construction & working of window air-conditioning?

This branch of science deals with the study of properties of moist air and its behaviour under different conditions. The properties of moist air include Dry-bulb Temperature (DBT), Wet- bulb Temperature (WBT), humidity. Relative Humidity (RH). etc.

How does a psychrometer work?

Psychrometers. A psychrometer measures humidity by taking both a wet-bulb and a dry-bulb temperature reading. With those two values known, the other properties of the air, including its moisture content, can be determined by computation or by reading a psychrometric chart.

What is psychrometry thermodynamics?

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 humidity ratio?

The humidity ratio or specific humidity is the weight of water vapour per unit weight of dry air (pound per pound or kg/kg). The retention capacity of moisture by air is a function of the temperature: the warmer the air, the more moisture it can hold.
