If the air is cooled to 80 degrees Fahrenheit, what will be the relative humidity? Notice that on the saturation curve osychrometric wet and dry bulb temperatures have the same values. How does a Psychrometric Chart Work?

Dry-bulb temperature is indicated on the x-axis of the psychrometric chart. Thank you for rating the program! The solution processes the data chartt from psychometric operations. You must be logged in to post a comment.

But more significantly, the psychrometric chart still serves as an important educational tool to professionals who want to learn more about how air humidification carfier.

The air in contact with the windows will become colder until the dew point is reached. Also, create custom labels anywhere on spychrometric chart.

Experiment with chart at various intersections of humidity ratio and air temperature to perform your own calculations! Therefore, the dewpoint temperature of the air at 90 degrees Fahrenheit wet-bulb temperature and 80 degrees dry-bulb temperature is 75 degrees Fahrenheit.

This second edition, available in both I-P and SI units, provides clear understanding of the state of the art in heating and cooling load calculation methods. New in the Third Edition: What is important to note, however, is that psychrometrics has a long, storied history of over one hundred years, and has been a vital mainstay of the air conditioning trade.

What is the dewpoint temperature of the air at 90 degrees Fahrenheit wet-bulb temperature and 80 degrees dry-bulb temperature? As you move your finger around the graph, the psychrometric properties at the top of the screen dynamically update.


One of the most important tools within psychrometrics is the psychrometric chart, invented by Willis H. The humidity ratio of this point is approximately.

Find the vertical line on the graph marked — this is the degrees dry-bulb line. Create psychrometric processes by plotting points then connecting them with process lines.

Easily plot HVAC and other psychrometric processes while out in the field, save the graphs, and then email the graph and results to yourself or clients. Once you are able to carriier the mathematics of the chart, it will make measuring the humidity of your systems quite an easy process.

At first appearence the psychrometric chart is quite confusing, however with some practice it becomes chatr extremely useful tool for rapidly evaluating air-conditioning processes.

Simplified, the amount of water vapor in the air. The humidity ratio is the located on the vertical axis. Type and press enter to search. Please add a comment explaining the reasoning behind your vote. It automatically generates chatt displaying power consumption.


Definitely review both guides before continuing. Our built-in antivirus checked this download and rated it as virus free. This program was originally created by Hands Down Software.

No, it is not an offshoot of Scientology—thank goodness. The area of engineering investigating the moist properties of air. Android app no longer available. Gatley, 16 The most relevant gases that psychrometrics examine are air and water vapor, as controlling a water vapor-saturated environment is important in the fields of air ventilation, humidification, agriculture, meteorology, etc.

Wet bulb temperature is represented by the diagonal lines that slope from right-to-left. Gatley, 17 Carrier compiled this data to create a descendant of the Psychrometric Chart, called the Hygrometric Chart:. The intersection of wet and dry bulb temperatures on the chart, together with the relative humidity line, can be used to determine all psychrometric properties of air.

Notify me of replies from other users. The latest installation package occupies F18 Carrier Landing Simulation. Understanding Psychrometrics serves as a lifetime reference manual and basic refresher course for those who use psychrometrics on a recurring basis and provides a four- to six-hour psychrometrics learning module to students; air-conditioning designers; agricultural, food process, and industrial process engineers; meteorologists and others.
