About This Seminar:
Building owners and tenants are concerned that environmental performance of buildings must be optimal while operating costs should be minimal. These goals can only be accomplished when a building’s HVAC and hydronic systems are properly balanced. Three major steps used to achieve the proper operation of the HVAC and hydronic systems and a desirable climate are testing, adjusting, and balancing (TAB).
** COMPLETION OF THIS COURSE DOES NOT CERTIFY YOU AS A TAB CT. IT WILL COUNT TOWARDS ALTERNATIVE EDUCATION OF PRE-REQS - PLEASE BE SURE TO SEND OVER YOUR COMPLETED CANDIDANCY APPLICATION TO CERTIFICATION@NEBB.ORG **
Formulas and Their Use:
Formulas are used daily by a TAB professional and should be memorized and applied appropriately as needed. Formulas include ratios of speed vs volume vs pressure vs BHP for air and hydronic systems. Other formulas that become necessary on occasion include V-belt length, BTUH, sensible, latent, and total heat, and others. Attendees will receive a list of commonly used formulas for their use and application.
Electricity:
Attendees will re-familiarize themselves with single vs three phase systems, how to measure voltage and amperage, overload protection, calculation of brake horsepower and the need for using safe practices and safety equipment for protection while gathering necessary measurements.
Fan Laws & Curves:
Fan affinity laws will be covered, and attendees will review how to apply known data to fan: curves. Instructors will discuss individual fan systems as well as fans in series and fans in parallel.
Pump Laws & Curves:
Pump affinity laws and how to apply known data to pump curves will be discussed and demonstrated. Individual pumping systems as well as open systems, closed systems, pumps in series and pumps in parallel and NPSH requirements will be covered.
Air Systems:
Various configurations of air systems such as supply, return and exhaust systems as well as constant volume, variable volume heat recovery, induction systems, active chill beam systems, and makeup air systems will be reviewed.
Psychometrics:
The use of a psychrometric chart as it applies to TAB and relates to the physical properties of air and the relationship of the properties to each other will be reviewed. Attendees will spend considerable time learning to plot psychrometric charts and understand the principles.
Problem Solving:
TAB Professionals identify problems and determine solutions or provide necessary information for responsible parties to address and correct the problem. This involves solid logic capabilities requiring the professional to exercise a systematic approach to the identification and resolution of problems or difficulties exposed by the TAB process.
Engineering Fundamentals:
The course will cover basic Heat Transfer and Fluid Mechanics as they relate to TAB.
TAB Procedural Standards and TAB Reports:
The course will cover the requirements of the NEBB TAB Procedural Standard and will address what constitutes a NEBB TAB Report.
COURSE COMPLETION:
The chapter numbers of each lesson are reference to the chapters in the NEBB Test, Adjust, and Balance (TAB) Technician Manual 2021. It is recommended that you read the chapters in conjunction with the lessons presented. You can obtain the formula sheet and psychrometric chart that is covered in the course at nebb.org under the recourse tab.
Air Homework and Hydronic Homework Lessons (Lessons 1 & 2):
The Air Homework should be done on your own after the Day 1-9 presentation. It will be reviewed in the next presentation, Day 2-1. The Hydronic Homework will be done together, on the Day 2-1 presentation, as a group. To download the PDF, right click on the PDF document and then "Save As".
Lessons 3 - 18:
After you watch the seminar presentation for each lesson, you will then answer 3 quiz questions. You have to get all 3 questions 100% correct with unlimited tries.
After completing all lessons, you will earn a Certificate of Completion for which will be located on your Learner Checklist tab.
Please Note: There might be times where there is a delay in sound but it will turn on once the presentation/video begins.
