This training course is suitable for a wide range of professionals but will greatly benefit:
HVAC Engineers
HVAC Consultants
HVAC Contractors
End Users Engineers
Duration
5 Days
Programme Overview
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 course 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 course 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 course will highlight:
HVAC Design concepts
Chilled Water System Piping
Heat Transfer and Selecting the proper Air Cooling System
HVAC Operation modes
HVAC Maintenance requirements
Objectives
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
Methodology
Participants to this training course will receive a thorough training on the subjects covered by the seminar outline with the Tutor utilising a variety of proven adult learning teaching and facilitation techniques. Seminar methodology includes presentation, pre-assessment and post-assessment tests, brainstorming, and participants case studies analysis.
