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.

State Board Acceptance

This course can be used by professional engineers to fulfill PDH requirements mandated by state and provincial licensing boards. Decatur Professional Development is an approved provider of continuing education in all states that pre-approve course providers. In all other states that mandate continuing education for engineers, it is the individual engineer's responsibility to determine the suitability of activities for PDH credit. The state boards typically accept online* courses that cover technical, managerial** or ethical content and which are relevant to the practice of engineering. The course must have a clear purpose or objective with a content that will maintain, improve or expand the skills and knowledge of the licensee's field of practice. For questions about your mandatory PDH requirements, visit the website of your state licensing board.

*Online courses are accepted by all state licensing boards that mandate continuing education. Other than New York (which limits online courses to 18 PDH) and Iowa (which limits online courses to 6 PDH), there are no limits placed by other states on the number of hours that can be earned through online continuing education. Consult with your state licensing board if you have any questions about the acceptability of online courses.

**The New York State Board of Engineers does not accept general office management courses, but will accept project management courses that are offered by an approved provider and that are technical in nature and contribute to the engineer's professional practice.
