This class is intended for HVAC consulting engineers, energy engineers, facility managers, property managers, final year technical students, site engineers, MEP coordinators, HVAC draftsman, mechanical inspectors etc..
Learn the fundamental principles of HVAC design, including psychrometric, heat transfer, mechanical refrigeration, and load estimating.
Use psychrometric principles and the P-h diagram to describe and analyze HVAC processes
Perform an accurate commercial load estimate that is the basis to the other system design decisions.
Make initial decisions based on a chilled water system and choose building control zones
Select a chiller and layout and select room fan coil units
Layout and select a cooling tower and a plate-frame heat exchanger
Design a chilled water piping system and a condenser water piping system
Select pumps for the piping systems and determine pumping power
Design a dedicated ventilation system using an applied air handler
Design a control sequence and strategy which meets the design condition for a chilled water system and many more.
This course covers the subjects that are fundamental in the design of all types of HVAC systems. Students learn the fundamental principles of HVAC design, including psychometrics, heat transfer, mechanical refrigeration, and load estimating. Participants will become proficient with HVAC’s two most important design tools, the psychrometric chart, and the cooling load calculation. At the completion of this course, participants know how to design commercial and residential buildings.
HVAC training objectives
At the conclusion of this course each student should be able to:
Explain the parameters that must be controlled to achieve human comfort
Explain the principles of heat transfer and their
impact on heating and cooling load estimates
Use psychrometric to describe air cycles
Apply the PH chart to describe the principles of mechanical refrigeration cycles
Describe the procedural steps common to all HVAC design
Zone a commercial building with fixed or open floor plan
Perform a block and zone load estimate for a commercial building
Training 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.
