HVAC (Heating Ventilation & Air Conditioning) is a science and professionalism known by a good population in this world but knowing and justifying the reason for the proper decisions and selections are great additions to any organization, company, facility, building, production, operation, maintenance and other departments. This training is planned to define the proper route for HVAC design, operation, and maintenance.
“Comfort conditions” are the golden words used by HVAC professionalism; these golden words need to be more specified, more customized, and accurately applied to reach customer satisfaction. This training introduces the standards which lead the definitions of the main parameters, requirements, limitations. By knowing where we are in this world; and what the atmospheric conditions are; and what the project conditions are, we can reach the expected end results and deliverables.
This training will highlight:
- HVAC Design concepts
- Chilled Water System Piping
- Heat Transfer and Selecting the proper Air Cooling System
- HVAC Operation modes
- HVAC Maintenance requirements
By the end of this training course, participants will learn to:
- Understand the HVAC design as materials and equipment
- Analyze the alternatives and select the best one
- Determine the proper AC Units
- Understand the operation modes
- Develop the maintenance tasks from the available manuals
Day 1
