Psychrometric Analysis Software: A Comprehensive Guide for Beginners

Psychrometric Analysis is a handy tool that helps you to create psychrometric charts. The charts are drawn with unmatched accuracy. It allows for complete psychrometric and process analysis, all graphically displayed. It also provides a professional state point and process report detailing all of the psychrometric and process values. One can copy the output chart or calculation reports directly to the Windows clipboard so that it can be pasted right into proposals, presentations or spreadsheets.

Elite's PsyChart 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. However, PsyChart is more than an electronic display of the standard psych chart. For example, it can quickly display numerical values of all properties for any selected point on the psych chart. Points on the psych chart can be labeled for future reference, and reports of their properties can be displayed on the screen or printer. Additionally, PsyChart allows psychrometric processes to be analyzed. 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.

The PsyChart program uses the psychrometric equations for moist air in Chapter 6 of the ASHRAE Handbook of Fundamentals. Rapidly converging iteration techniques have been employed to allow PsyChart to solve problems with virtually any combination of input parameters.

Besides the on-screen display of psych charts, there are three additional reports provided. They are the State Point Report, the Process Energy Report, and the Process Input/Output Report. The State Point Report lists all six psychrometric parameters for all defined state points. The Process Energy Report lists air volume, sensible, latent, and total loads, along with water addition/removal rates for all defined processes. 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. 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.

There are several properties displayed on a psychrometric chart. These include dry-bulb temperatures, wet-bulb temperatures, dew point temperatures, relative humidity, humidity ratio, specific volume, and enthalpy. A link takes you to a downloadable software program. It allows users to electronically plot conditions on a psychrometric chart. This program version permits the user to enter state points and graph the air conditioning process, while calculating additional air properties.

Analyze the physical and thermodynamic properties of gas-vapour substances. Generate and edit psychrometric charts with the optimal accuracy, replace the existing elements and values with new ones, then verify the integrity and functionality of the results.

These charts focus on the range of temperatures most suitable for comfort-cooling HVAC applications, and include the Trane coil curves, which depict the condition of the air leaving a cooling coil.Also, printed psychrometric charts are available to order.

The terms psychrometry and psychrometrics refer to the study of moist air and its thermodynamic properties. Whilst obviously important in the design of air-conditioning systems, these same thermodynamic properties are key determinants of thermal comfort within a building, which makes psychrometrics an important part of any passive and/or climate-responsive design process.

When it first starts up, the app displays a standard empty psychrometric chart. You can choose to add or remove axis lines for a range of different metrics, or even highlight individual axis lines in red to assist with dynamic explanations or interactive presentations. You can do this using the checkboxes and highlight buttons in the CHART METRICS panel located on the left side of the chart.

The default metric displayed when first showing grid data is the frequency distribution of temperature and humidity. This is essentially the number of unique data points within the area of the chart covered by each grid cell. This is always shown in blue and is useful for understanding the range of psychrometric conditions within the data. However, you can also choose to map any other metric in the data, which you can set using the SELECT DISPLAY METRIC dialog box. This information is shown using a different colour scale.

Having previously taught psychrometrics to architects, I always found it challenging to convincingly explain why the psychrometric chart used humidity ratio or absolute humidity in the vertical axis instead of the more familiar metric of relative humidity, and why it was so important to understand the various metric lines. Thus, one of the reasons for developing this tool was to see if I could morph seamlessly between the standard psychrometric chart and the much simpler relative humidity chart. The hope was that by simply animating back and forth between the two chart types, most of that explanation would become pretty obvious as you get to see clearly almost all of the psychrometric processes change from straight lines under the absolute humidity axis to complex curvilinear lines under relative humidity.

In addition to comfort data, you can also overlay lines that represent standard psychrometric processes such as sensible heating and cooling or humidification, etc. These lines project from the current indicator position and update automatically and dynamically whenever the indicator position is changed.

Added a checkbox in the PROCESS LINES panel to toggle the position indicator on and off. This is the smallcursor that you can interactively drag around the chart to show the psychrometric conditions at that point. Whenoff, the data values shown in the top-left of the chart are also hidden. The displayed points then show the averagehourly values over the currently selected period.

The EE factor is a measure of the predicted drying rate occurring in the wetted tablet bed, and if EE is kept constant, it is proposed that equivalent film coating quality can be obtained upon scale-up or changes in operating parameters. While the equation for EE is arrived at via a coupled heat and mass transfer analysis, the aim of this work is to show that EE is equivalently expressed by relating the internal thermodynamic conditions to the saturation conditions (i.e., where the exhaust is fully saturated or 100% relative humidity (RH)) along a constant enthalpy line on a psychrometric chart. This model, by using a few reasonable approximations, reduces the published equation for EE to a greatly simplified expression. The benefits of this approach will be discussed in relation to process understanding, process design and scale-up, as well as the Quality by Design concept of design space.

Generally speaking, the Design of Experiments approach is usually the most effective starting point for developing a design space for a unit operation where a first-principles understanding is lacking or insufficient to adequately describe the relationships between the relevant parameters. For a three-parameter design space for a tablet film coating, a traditional DoE screening design approach might employ a three-factor two-level factorial design consisting of nine to twelve experiments to roughly define the design space, while optimization of the design space may involve composite designs with more experimental points. A reduction in dimensionality of the design space from three parameters to one, by expressing the thermodynamic condition of the aqueous coating using E, would therefore represent a significant decrease in the experimental effort needed to develop a science-based tablet coating process. Additional benefits of using E as a single design space dimension would be (1) increased process flexibility, since coating parameters are allowed to vary only under the constraint that E alone fall within a certain range, and (2) clarity of process description and understanding, since E can be easily illustrated and understood via a psychrometric chart.
