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 the successful completion of this program, the participant 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

• Maintenance Engineers, technicians and staff
• Plant engineers
• Operation, maintenance, inspection and repair managers, supervisors and engineers
• Mechanical engineers and technicians
• Design engineers ,electrical engineers and technicians, consulting engineers
