Reading a psychrometric chart

The psychrometric chart (Figure 108-2) is a tool for understanding the relationships between the various parameters of supply air and the relative humidity.This template allows a designer or operator to “work backwards” from a desired room relative humidity to the desired condition of the air as it enters the supply duct. Properties of atmospheric air such as, the dry-bulb temperature, the wet-bulb temperature, the dew-point temperature, the specific humidity, the relative humidity, specific enthalpy and specific volume are discussed in relation to the psychrometric chart below.. Two independent intensive properties are required to completely specify the state of air in the psychrometric chart. Display a fully customizable psychrometric chart in both landscape and portrait modes. Customize the graph in many different ways, including specifying the psychrometric chart line colors, chart background color, hide/display status of chart lines, point colors, process line colors, units of graph values, and the min/max limits of the chart.

How to Read The Psychrometric Chart & A Detailed Chart. One may ask, why should we bother to learn how to read a psychrometric chart? After all, we have myriad online calculators, tables, smart phone apps, etc. Most of our instruments perform the conversions as a built in feature. At Rotronic, we aim to help you make a better measurement.

26 Sep 2016 However, we are going to invoke the dreaded psychrometric chart to help us then move horizontally to the right to read the Humidity Ratio. When illustrating the air condition in a project or job notes it might be clearer to refer to a printed chart (possibly conveniently plastic coated and reusable) to read  Reading a Psychrometric Chart. 295.

Psychrometric charts are used by engineers and scientists to visualize the relationships of gases and vapors. While the charts may look complex, they’re relatively easy to read when you know what each part of the graph is representing. By identifying the axes and reading the markings on the interior of the chart, you can plot points and draw conclusions from known measurements on the chart
