Day One: HVAC Systems Design

• Sources of heat load
• Using the equation of each heat load for analysis and possible reduction in the heat load
• Air treatment and human comfort
• Evaluating and studying the outside and inside design conditions to meet the human comfort
• Daily and monthly heat load profiles, how they affect the heat load
• Selecting the type of AC system

Day Two: Piping System for Chilled Water Applications

• Velocity/friction loss VS initial and running cost. How to decide which way to go
• Closed or open type systems. (Advantages and dis-advantages of each type)
• Pressure breakers and the need for high rise buildings
• Expansion and contracting of the piping circuits and the selection of expansion joints, pressurized expansion & make up tanks
• Refrigerants and their effect on AC systems selection and the environment

Day Three: Heat Transfer and Selecting the Right AC System

• How cooling towers work for centralized water-cooled systems
• Thermal storage
• Types of thermal storage systems
• Air cooled systems Load shifting (partial and full), daily and weekly, case study with calculations and comparison of C.O.P
• Ventilation, infiltration, ex-filtration. How to minimize their heat loads
• Factors used to select the right AC system

Day Four: HVAC Operation

• System components
• System start-up preparation
• System running conditions
• Systems sequence of operation
• System monitoring
• System partially stopping
• System shutdown

Day Five: HVAC Maintenance

• Scheduled preventive maintenance routines
• Daily log sheets and the monitored items and logged records
• Utilizing records history for improvement of systems reliability
• Hand over package and its importance for proper maintenance
• Training of hands on staff for better understanding of the systems to reduce down time and operational cost
• Operation and maintenance case studies
• Open discussions including any specific related cases from attendees
