This CD includes all five of ASHRAE's I-P unit psychrometric charts and all seven SI psychrometric charts. 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.


NOTE: In this psychrometric chart the abscissa is the dry-bulb temperature, and the mean radiant temperature (MRT) is fixed, controlled by the inputbox. Each point on the chart has the same MRT, which defines the comfort zone boundary. In this way you can see how changes in MRT affect thermal comfort. You can also still use the operative temperature button, yet each point will have the same MRT.


NOTE: In this psychrometric chart the abscissa is the operative temperature and for each point dry-bulb temperature equals mean radiant temperature (DBT = MRT). The comfort zone represents the combination of conditions with the same DBT and MRT for which the PMV is between -0.5 and +0.5, according to the standard.


NOTE: This chart represents only two variables, dry-bulb temperature and relative humidity. The PMV calculations are still based on all the psychrometric variables, but the visualization becomes easier to understand.


NOTE: This chart represents only two variables, air speed against operative temperature. The operative temperature for each point is determined by dry-bulb temperature equals mean radiant temperature (DBT = MRT). The calculation of PMV comfort zone is based on all the psychrometric variables, with PMV values between -0.5 and +0.5 according to the standard.


Excel is my favourite tool to design Pharmaceutical HVAC systems (but not the only). I always like to have a graphical view of the system. I normally use an Excel file with all calculations in several sheets (air changes, leakages, gains, etc.), and finally, a plot summarizing the calculations. We can plot easily a psychrometric chart in Excel.


The formulations used here to calculate moist air properties are based on perfect gas relations published in 1989 ASHRAE Fundamentals Handbook, which should be accurate. Nevertheless, It is strongly recommend that you to compare the results calculated by this worksheet with a psychrometric chart. There is no error checking so you should use reasonable input values. 1e1e36bf2d
