Heating, Ventilation& air conditioning (HVAC) Systems

This program 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.

Either it is a small warehouse or a complex high-rise building, there is an increasing demand by owners and engineers to design and install the HVAC 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.

By the end of this program, participants will have enough knowledge to implement their daily assignments correctly and professionally.
