• 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 course delegates will be able 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

Organizational Impact:

Improving the operation and maintenance staff performance, which will lead to a budget reduction by: 

• Reducing the amount of improper operation
• Reducing the improper maintenance
• Increasing the end user’s satisfaction
• Reducing the Mean Time to Perform Maintenance
• Increasing the Mean Time Between Maintenance
• Reduce Initial and Running costs and Increase the HVAC systems

Personal Impact:

Using the “Plan – Do – Check – Act” as a routine sequence in any HVAC activity will help you to:

• Define the proper design which will reduce the initial and running costs
• Perform a proper interpretation for the HVAC equations, to reduce costs and increase efficiency
• Select the proper materials & HVAC equipment to reduce the operation and maintenance efforts
• Define the needed control system to reduce the operation costs and staff
• Define the needed maintenance tasks to reduce costs and time, and increase efficiency
• Define the improvement needed in your systems

This training course is suitable to a wide range of professionals but will greatly benefit:

• HVAC Engineers
• HVAC Consultants
• HVAC Contractors
• End Users Engineers

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.
