Description 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 psychometry 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 in this course.
Manufacturer equipment performance data is provided with correction methods when conditions vary from rated values. Performance data are provided for packaged ACs, Roof Top Units (RTUs), air and water heat pumps, furnaces, chillers, compressors, cooling towers, hydronic coils, pumps, and fans. The course also provides many useful rules of thumb to aid the beginning individual in the design and sizing of HVAC systems. The experienced individual may find them useful for a quick design and operation check.
Topics are introduced for individuals who have little background on the subject while providing valuable information for personnel having experience with HVAC systems.Objectives
To provide a practical understanding of the theory dictating the design and control of HVAC systems.Who Should Attend
To provide systematic sizing and selection procedures of various HVAC equipment.
To provide information on efficient operation, energy conservation, and economics of HVAC systems.
Design and project engineers and technologists, plant and facility engineers, consultants, mechanical engineers and technologists, maintenance and operation personnel and other technical personnel who need to upgrade/refresh their current knowledge of HVAC systems.
