Who invented psychrometrics?

Willis Carrier is known as the Father of Air Conditioning. He also invented the psychrometric chart. It was a result of his research studying the effects of heat and humidity on heat and cooling comfort.

What is the importance of psychrometry?

Psychrometrics is the study of the air and water vapor mixture. Proficiency in the use of the psychrometric chart is an important tool for designers of air conditioning systems. Psychromet- rics is required to properly calculate heating and cooling loads, select equipment, and design air distribution systems.

What is Psychrometrics state its applications?

Common applications Although the principles of psychrometry apply to any physical system consisting of gas-vapor mixtures, the most common system of interest is the mixture of water vapor and air, because of its application in heating, ventilation, and air-conditioning and meteorology.

What is moisture in the air called?

humidity, the amount of water vapour in the air.

What is the importance of Psychrometry in the design of the air conditioning system?

Psychrometrics can be used to predict changes in the environment when the amount of heat and/or moisture in the air changes. Use of psychrometric analysis is also important to determine the volume flow rates of air to be pushed into the ducting system and the sizing of the major system components.

What is Psychrometry What do you mean by relative humidity?

Relative humidity can also be expressed as the ratio of water vapor pressure – pw, to the water vapor pressure of saturated air at the same temperature – pws. Relative humidity is expressed as a percentage. The moisture-holding capacity of air increases with air temperature.

How do you explain a psychrometric chart?

A psychrometric chart is a graphical representation of the psychrometric processes of air. Psychrometric processes include physical and thermodynamic properties such as dry bulb temperature, wet bulb temperature, humidity, enthalpy, and air density. A psychrometric chart can be used in two different ways.

What is RH humidity?

Put simply, relative humidity (RH) is a measure of the water vapor content of air. More explicitly, it is the amount of water vapor present in air expressed as a percentage (%RH) of the amount needed to achieve saturation at the same temperature.
