Mastering the fundamentals and basic concepts of HVAC is necessary for individuals involved in the design, operation, and maintenance of HVAC systems. This course provides an understanding of the basic concepts of HVAC systems covering fundamentals of refrigeration, heat transfer, and psychometrics, HVAC equipment and system selection, comfort, cooling and heating load calculations, design of air and water distribution systems, controls, energy costs and economics. All topics are introduced at a level suitable for individuals who have little background in the subject. The course comprises lectures and hands-on workshops. Through a set of case studies, in each workshop you learn the use of useful computer programs that incorporate design, sizing, and equipment selectio
