Please note, This instructor-led course has specific dates and times:
This course is held online over 5 days on the following schedule (All times in Eastern Time Zone):

10:00 am to 5:00 pm Eastern (Will include the usual breaks)

After attending the course, you will be able to:

  • Apply key fundamentals in the design and operation of HVAC systems.
  • Perform air conditioning cycle, load, duct and hydronic piping design calculations.
  • Select procedures for efficient operation of various HVAC equipment and systems
  • Recognize energy saving opportunities in HVAC systems using the insight gained at the course into energy cost saving opportunities.
  • Design efficient controls for your HVAC systems

Mastering fundamentals, sizing, selection, and operation is a must for designers and operators of HVAC systems. This course covers the fundamentals of HVAC systems starting from Psychrometry and representation and calculations of air conditioning processes and cycles. Cooling and heating load calculations, design of air distribution systems, HVAC equipment and system selection, controls, energy conservation and economics of HVAC systems are all covered. The use of Carrier's Hourly Analysis Program (HAP) in the design and sizing of HVAC Systems is demonstrated. Many useful rules of thumb to aid the beginning individual in the design and sizing of HVAC systems will be provided. The experienced individual will find them useful for a quick design and operation check.
