CSD 500 at-a-glance

This class is intended for HVAC consulting engineers, energy engineers, facility managers, property managers involved in the selection, design, operation or maintenance of commercial buildings using constant volume air distribution system with single zone packaged and split system equipment.

  • Determine building zones and acceptable compromises in comfort control
  • Design the air distribution system
  • Learn to size the duct system
  • Select packaged (rooftop) and split system equipment
  • Develop a sequence of control

Class Overview

Comfort conditions for spaces in a commercial building may be achieved in one of two basic ways: by applying single zone units to each space or by using systems that provide control to multiple spaces. This course centers on the skills and knowledge necessary to design one of the most common HVAC systems, a constant volume air distribution system using single zone packaged and split system equipment. The principles taught in this class will help anyone involved in the design or renovation of projects using single zone packaged equipment to develop more quickly cost-effective designs. Participants learn to determine building zones and acceptable compromises in comfort control. How to design the air distribution system for good air motion and sizing of the duct system is covered in detail. Achieving the most effective selection of packaged (rooftop) and split system equipment is covered and how to develop a sequence of control to maintain comfort design. Participants use workshops to apply the material covered in the class to a typical project. Computer-assisted work sessions are used to practice the skills.

Who Should Attend this training

This course is for HVAC engineer contractors who are doing design build projects. A working knowledge of building design, light commercial HVAC equipment and basic computer skills are required.

Class Objectives

Learning Objectives

At the conclusion of this course, each student should be able to:

  • Explain the application of green building principles
  • Choose building zones when served by a single zone unit and make initial system decisions
  • Layout and select air terminals
  • Layout and design low pressure duct systems
  • Select the best type of packaged units that will meet the required zone psychrometrics conditions
  • Select and establish fan performance based on air system design conditions
  • Design a control sequence and strategy which meets the design condition

Learning Methods Used

This course uses a combination of classroom lecture, videos, lab tours of commercial equipment, demonstrations and workshops to present the material. Student’s achievement of the learning objectives is determined by successful completion of the workshops, quizzes and final written exam. Workshops are instructor guided exercises using the procedures taught in the lectures.
