Units-system: Metric(SI) or Imperial(I-P). This affects the chart, input and calculated values. In the chart settings (icon under the chart), you can adjust theTemperature AxisandHumidity Ratio Axis, enable and set yourComfort Areaand define theAir Density. ...
Pressure Units: This picker control allows you to select from a wide variety of pressure units for either English or Metric. Display Wet-Bulb Lines: This selector control allows you to display or hide the wet-bulb lines on the psychrometric chart. Select "No" to hide the wet-bulb lines...

So the enthalpy of dry air below 0oF is a negative value. The enthalpy of moisture below 32oF is not a factor since most of it will have condensed and then frozen out as ice from the air. In metric (SI) units the enthalpy of both the dry air and water vapor is measured from 0...
A lot of folks have been involved in the development of the psychrometric chart over the past century. Willis Carrier was the first, with what he called the hygrometric chart in 1904. Richard Mollier from Germany made an important contribution in 1923, as you’ll see in the next section. ...
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. Further, the chapter analyzes ...
You can specify additional parameters such as the altitude of the air being analyzed, the atmospheric pressure, different types of units such as degrees F or R, and English or Metric units. The "HVAC Psychrometric Plus" application was designed by Carmel Software Corporation, a leader in HVAC ...
