Psychrometric Properties Air Conditioning Processes Pdf Humidity Examples of psychrometric properties example 1 find the moisture content of air at 25oc dry bulb temperature and 25oc wet bulb temperature. referring to the chart below, a vertical line is drawn upwards from 25oc dry bulb temperature until it intersects at 25oc wet bulb temperature. this intersection point happens to be on the 100% saturation line. Examples are provided to demonstrate how to use a psychrometric chart to find various air properties given two known conditions. basic air conditioning processes like mixing, sensible heating cooling, and cooling with dehumidification are also outlined.
Solved Example 10 1 Determination Of Psychrometric Chegg Evaluate and compare air water mixture properties for dewpoint, humidity ratio, wetbulb, enthalpy, and mixture specific volume using the following 3 different methods". All psychrometric properties of air are determined by measuring two psychrometric variables: for example, if wet and dry bulb temperatures are measured, then relative humidity, vapor pressure and dew point. This chapter presents a psychrometric chart, which shows the properties of moist air in terms of dry bulb temperature, wet bulb temperature, relative humidity, humidity ratio, and enthalpy. three of these properties are sufficient to identify a state of moist air. This chapter includes basic coverage of psychrometric properties and psychrometric processes. emphasis is upon properties and processes relative to the environment and to processing of biological materials.

This chapter includes basic coverage of psychrometric properties and psychrometric processes. emphasis is upon properties and processes relative to the environment and to processing of biological materials. By understanding the psychrometric properties of air and water vapor mixtures, builders and designers can create buildings that are not only energy efficient but also comfortable and durable. In this example, an electric resistance heater is installed in an air duct. the heater is needed to heat 650 pounds per hour of air from 75 degrees fahrenheit to 95 degrees fahrenheit. the problem is to find the capacity of the heater in kw. the process line is shown here on the psychrometric chart. These psychrometric properties form the basis of the psychrometric chart below (figure 1), in which the curves correspond to relative humidity (or percentage saturation), the horizontal lines correspond to moisture content and the vertical lines correspond to air (dry bulb) temperature. Introducing the psychrometric chart – how we create the psychrometric chart from the thermodynamic properties of moist air tables and scale for the eight different properties.
