Jim Richardson (CE Department UA) and Barbara McCrary of Hattemer, Hornsby & Bailey, Pratteville, AL for assistance in learning the use of Visual Basic macros in Excel that permit the calculation of psychrometric values using functions. It permits the quick calculation of basic HVAC air mixing, cooling, heating and heat recovery processes. The program can replace the Psychrometric chart and users are encouraged to compare values. How to draw a psychrometric chart and identify various properties of air.Please provide feedback on this module by selecting 'Like' or 'Dislike'. ![]() This Psychrometric Processes Program follows equations provided in the 2005 ASHRAE Handbook of Fundamentals, Chapter 6. Calculate thermodynamic properties based on dry bulb temperature, relative humidity and pressure at 1 bar or 14.5 psi. 1, Psychrometric chart (Mollier Diagram), Air pressure: 100, kPa. ![]() ![]() Total, sensible, and latent capacities computed for cooling and heat recovery processes. We developed some Excel spreadsheets for mechanical engineer use for FREE. 1, Psychrometric chart, Air pressure: 100, kPa. It also calculates resulting properties for air mixing, cooling, and heat recovery. PsychProcess09 is a program for computing the properties (enthalpy, specific volume, humidity ratio, relative humidity, specific heat, and dew point). ![]()
