Engineers and technicians of various skill levels and backgrounds will find this program specifically tailored to their needs as it offers a comprehensive introduction to the core principles of Heating, Ventilation, and Air Conditioning (HVAC). The program begins by reviewing psychometric charts and subsequently delves into the factors that impact design decisions, indoor air quality, load calculations, and HVAC systems.

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 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
