Psychrometrics Through Computer Simulation

Manuel Calzada, P.E.

Overview

Solving some HVAC problems can be, quite frankly, very tedious work.  Mixing of air streams, heating and cooling coil processes, and HVAC system simulation all require laborious calculations by the engineer. 

In this course, you will learn how to solve these problems using a spreadsheet program, which is included as part of the purchase price for the course.  The course first covers the fundamentals of common HVAC processes.  Mass and energy balance equations are reviewed and use of the psychrometric chart is covered.  Practical applications, such as air mixing and cooling coil calculations are then covered through the use of examples.

The student must take a multiple-choice quiz consisting of twenty-seven (27) questions at the end of this course to obtain PDH credits.

As a bonus for the student, a link to an HVAC process calculator (in an Excel File) is provided in the course quiz.  This calculator, which is included in the course purchase price, is a handy tool that will save you time when performing HVAC calculations.
