Seminar Overview

Controlling air distribution for the comfort of the people in it is one way to ensure an efficient workplace.  Designed for any worker involved in air distribution systems, this seminar will take students from the basics of HVAC electrical controls through air distribution and troubleshooting.

Overall, this HVAC Electrical Controls & Air Distribution training program is designed to teach students how to “control” their electrical controls and use fundamental air distribution principles for achieving consistent HVAC comfort and efficiency in buildings, plants and facilities.

This seminar is $550 per day or $1100 for both days.

Day One - Discussion Topics

HVAC system problems can be divided into three major categories - Air Distribution, Electrical or Mechanical. The part that causes most service headaches is the electrical portion and most of that can be traced back to control problems. So day one of this Electrical Controls & Air Distribution seminar concentrates on overcoming the most common service problems encountered in HVAC systems by teaching students to understand, troubleshoot and test HVAC electrical controls.

Basic Electricity

  • Basic electricity & Ohm’s Law
  • Meters & tools for taking electrical measurements
  • Electrical circuits: series & parallel

Control Circuits

  • Schematics
  • Ladder Diagrams
  • Developing Wiring Diagrams

Controls

  • Overloads
  • Relays
  • Contactors
  • Control Transformer
  • Starting Relay
  • Defrost Timer
  • Thermostat
  • High Pressure Control
  • Low Pressure Control
  • Oil Pressure Control

Troubleshooting

  • General Troubleshooting Techniques
  • Common Problem Areas
  • Commercial Air Conditioning
  • Heat Pump Control
  • Pump Down Cycle

Day Two - Discussion Topics

Many common problems found in HVAC systems are relatively easy to correct, but are often overlooked. These problems are not electrically related at all even though many times we can get tricked into thinking they are. Yet a non-electrical problem can be as frustrating to find and fix as an electrical one, and may be even more discomforting to the people who have to live with it. So in day two of this Electrical Controls & Air Distribution training program we’ll help you eliminate the complaints of "too hot", "too cold", "not enough air" or "I feel a draft", by concentrating on the most often overlooked and ignored problems in HVAC systems – the "V" in "HVAC" – or ventilation, air distribution and air balancing!

Determining and Improving Air Flow
