About the course
This course is designed for engineers and technicians from a wide range of abilities and backgrounds and 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 influence design choices, indoor air quality, load calculations and heating/ventilation and air-conditioning systems. Numerous tips and tricks throughout the program make it very practical and topical to your applications.
Ether it is a small warehouse or a complex hi-rise building, there is an increasing demand by Owners and Engineers to design and install the HVAC & R systems in a more efficient and cost-effective manner. Due to the on-going advances in HVAC & R technology, 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 details of heat load calculations, selection of appropriate equipment/system and the design of the ducts and piping networks
- A comprehensive design case study of a complete cold store including heat loads of individual rooms and the total cold store, selection of the appropriate equipment, design of the best layout including handling areas
- By the end of this program, participants will have enough knowledge to implement their daily assignments correctly and professionally.
The aim of this program is to provide the participants with a complete and up-to-date overview of the area of Heating, Ventilation and Air-conditioning (HVAC). It commences with a review of psychometric charts and then examines the factors that influence design choices, indoor air quality, load calculations and heating/ventilation and air-conditioning systems. Numerous tips and tricks throughout the program make it very practical and topical to your applications.
