Heating, Ventilation and Air-Conditioning(HVAC) Systems

Numerous tips and tricks throughout the program make it very practical and topical to your applications. 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.

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.

Course Objectives

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.

Upon successful completion of this course, the delegates will be able to:

• Maintain and troubleshoot HVAC systems
• Understand and apply the psychometric chart
• Design for good air quality
• Perform basic load calculations
• Initiate an effective inspection and maintenance program
• Minimize forced outages and prevent serious damage to HVAC equipment
• Provide an overview of the legislative requirements plus the essential steps and responsibilities for the maintenance and repair of HVAC Systems
• Outline the technologies available for the efficient energy management using HVAC systems
