This course will provide an excellent introduction to the fundamentals of Heating, Ventilation and Air-conditioning. It commences with a review of psychometric charts and then examines the factors that nuance design choices, indoor air quality, load calculations and heating/ventilation and air-conditioning systems. The course is introducing many important subjects: The details of terminologies, psychometric processes, heat load calculations, selection of appropriate equipment/system, Installation procedure of equipment’s, its maintenance and troubleshooting.
The course provides overview of operation and maintenance (O&M) programs specially designed to enhance HVAC systems without sign cant capital investment. The intent of this paper is not to provide hardcore maintenance or troubleshooting aspects but an insight to O&M practices that can ensure the best performance and comfort for your system.
Special examples are provided for typical HVAC troubleshooting problems that have occurred in the Instructor’s experience. It is essential that participants have a fundamental understanding of the subject matter if they are to successfully design to avoid problems, as well as diagnose HVAC problems when they occur
Due to the on-going advances in HVAC system, this demand is becoming a must and often controlled by new governmental regulations and engineering codes. Realizing this need and the importance of the subject, the course is introducing this specialized program concentrating on two important subjects, the details of heat load calculations, selection of appropriate equipment/system and the design of the ducts and piping networks, in addition to installation and maintenance and trouble shootings.
