Thompson, 2 The technical nature of this early psychrometric chart is not very important for your understanding, as the modern psychrometric chart incorporates new variables, which will be explained later.
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. Catrier suite features customizable presentation parameters and offers editing tools for the input content adjusting the charts in real time. Psychometric points, processes and associated energy values are automatically calculated and plotted right on a professional psychometric chart.
PSYCHROMETRIC CHART CARRIER |
It automatically generates charts displaying power consumption. The technical aspects of the modern psychrometric chart will be discussed below. Now find the diagonal right-to-left line marked 70 degrees, and envision an imaginary line to the degrees vertical line. Purchase Understanding Psychrometrics, psycrhometric ed.
Create an unlimited number of psychrometric chart projects. Indicate all the values determined on the chart. Find the vertical line marked How does a Psychrometric Chart Work? Find the vertical line on the graph marked — this is the degrees dry-bulb line.
History of the Psychrometric Chart One of the most important tools within psychrometrics is the psychrometric chart, invented by Willis H.
Also, you can create templates that you can reuse over and over again. The proportion of humidity in the air at a given temperature relative to its maximum. Once you are able to understand the mathematics of the chart, it will make carrrier the humidity of your systems psyychrometric an easy process.
The upmost, leftward-curved line in the psychrometric chart represents the maximum of water vapor that is present in the air at a given temperature. Psychrometrics, at its core, is an area of engineering investigating the moist properties psychromwtric air. Want to teach an old HVAC dog some new tricks? A cooling of air temperature represents a shift to the left.

Notice that on the saturation curve the wet and dry bulb temperatures have the same values. An interesting application of using a swamp cooler to cool drinking water in extremely hot environments is described in the posting of Rich Oppel in the At War blog of the New York Times: 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.
Now, imagine a vertical line psychgometric from the point to the dry-bulb temperature x-axis. Load Calculation Applications Manual, 2nd ed.
I must char you—I am going to get a bit technical, and you just might learn something at the end of this paper. What is the humidity ratio at this point? The most popular chart in common usage is that developed by ASHRAE American Society of Heating, Refrigeration and Air-Conditioning Engineershowever we feel that the construction of a simplified version of the chart based on approximations of the various equations can be a very useful tool for developing an psychrometriic of it’s usage.
A dry bulb air temperature thermometer reads degrees Fahrenheit and a wet bulb thermometer reads 68 degrees Fahrenheit. The program on the CD allows the user to plot typical psychrometric processes and perform the corresponding energy calculations on-screen, without having to first print out the individual charts.
PSYCHROMETRIC CHART CARRIER
Using the Psychrometric Chart neatly plot the required air conditioning process and estimate a the amount of moisture removed [ Gatley, 17 Carrier psycrhometric this data to create a descendant of the Psychrometric Chart, called the Hygrometric Chart: Here is a modern version of the psychrometric chart:. No, it is not an offshoot of Scientology—thank goodness. Create psychrometric processes by plotting points then connecting them with process lines.
One of the most important tools within psychrometrics is the psychrometric chart, invented by Willis H. Thus we introduce an oblique enthalpy axis and enthalpy black lines as follows: If the air is cooled to 80 degrees Fahrenheit, what will be the relative humidity?
