W H Carrier, rational psychro- metric formulae, psychrometric chart, invention of centrifugal. These reports provide complete data listings concerning state point conditions, sensible and latent loads encountered from state point to state point, and psychrometric conditions created by each process.Willis H Carrier. The Process Input/Output Report lists the air volume rates, percentages for mixing and collecting processes, and the input and output state conditions for the processes. The Process Energy Report lists air volume, sensible, latent, and total loads, along with water addition/removal rates for all defined processes. The State Point Report lists all six psychrometric parameters for all defined state points. They are the State Point Report, the Process Energy Report, and the Process Input/Output Report. Program Outputīesides the on-screen display of psych charts, there are three additional reports provided. Seven processes are allowed including: general linear processes, heating, cooling and dehumidification, collection, mixing, and various processes for air as it passes through a zone. Alternatively, a state point can be defined by using the cursor to locate the position. A single state point can be defined with any two of the following inputs: dry bulb temp, relative humidity, enthalpy, wet bulb temp, humidity ratio, and dew point. Menu selections are provided to define, label, and erase state points. As selections are made and values entered, the results are immediately displayed on the screen. The Ps圜hart program is completely interactive in that the chart is continuously displayed while menu selections are presented at the bottom of the screen. Rapidly converging iteration techniques have been employed to allow Ps圜hart to solve problems with virtually any combination of input parameters. The Ps圜hart program uses the psychrometric equations for moist air in Chapter 6 of the ASHRAE Handbook of Fundamentals. Extensive Help / User's Guide embedded in the program, including fully-worked examples.Allows customization of toolbars and menus.Allows saving the chart image as a bitmap or to the Clipboard.

Windows enhance the clarity of processes where state points tend to crowd together. In order to view sections of the psych chart in fine detail Ps圜hart allows the user to zoom in and create an expanded "window" around the selected region of the psych chart.
The user can further customize the psych chart by specifying to show or omit any of the property lines which can be displayed with either English or SI metric units. The lines for all standard psychrometric processes, such as heating and humidification, cooling and dehumidification, mixing, collecting, etc., are displayed on the chart with simple user commands.Īlthough the initial display is the standard ASHRAE sea-level chart, this can be changed by the user to show a chart for any elevation or pressure, and for any range of dry bulb temperatures.
Additionally, Ps圜hart allows psychrometric processes to be analyzed.
Points on the psych chart can be labeled for future reference, and reports of their properties can be displayed on the screen or printer. For example, it can quickly display numerical values of all properties for any selected point on the psych chart. However, Ps圜hart is more than an electronic display of the standard psych chart. Elite's Ps圜hart program colorfully displays the psychrometric chart on the computer screen and allows the designer to carry out all operations and analysis normally done using a conventional psychrometric chart.
