COURSE OVERVIEW:

Modern HVAC operations and troubleshooting technology represent a critical convergence of mechanical engineering, thermodynamics, and electronic control systems. This course provides a comprehensive exploration of high-efficiency heating, ventilation, and air conditioning systems used in industrial and large-scale commercial facilities. Participants will examine the transition from traditional constant-volume systems to modern variable-speed and smart-controlled environments that prioritize indoor air quality and energy conservation.

The scope of this training encompasses the technical cycle of refrigeration, airflow dynamics, and hydronic system management. Coverage includes the operation of centrifugal and screw chillers, air handling units (AHUs), cooling towers, and sophisticated Building Management Systems (BMS). Emphasis is placed on the integration of sensors and actuators that allow for real-time monitoring and adjustment of environmental parameters, ensuring thermal comfort while minimizing the carbon footprint of the facility.

Furthermore, the course addresses advanced diagnostic methodologies for resolving complex system malfunctions. Trainees will learn how to utilize pressure-enthalpy diagrams and electronic diagnostic tools to identify refrigerant leaks, compressor inefficiencies, and air balance issues. By mastering these modern troubleshooting techniques, HVAC technicians and facility engineers can ensure peak equipment performance, extend the service life of expensive mechanical assets, and maintain a safe and productive environment for building occupants.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Apply the fundamental principles of the vapor compression cycle to HVAC operations.
• Identify the major components and functions of industrial chilled water systems.
• Evaluate the performance of Variable Air Volume (VAV) versus constant volume systems.
• Interpret psychrometric charts to manage humidity and indoor air quality effectively.
• Utilize Building Management Systems (BMS) for real-time HVAC performance monitoring.
• Diagnose the root causes of compressor failures and motor overheating.
• Implement advanced refrigerant leak detection and recovery procedures.
• Optimize cooling tower operations to manage thermal loads efficiently.
• Balance airflow in complex ducting networks using modern anemometry tools.
• Troubleshoot electronic expansion valves and digital thermostat logic.
• Analyze the impact of filter maintenance on system static pressure and energy use.
• Execute a systematic startup and shutdown procedure for large-scale chillers.
• Recommend energy-saving retrofits for older HVAC installations.

TARGET AUDIENCE:

This course is intended for HVAC Technicians, Facility Engineers, Maintenance Supervisors, and Plant Managers responsible for the operation of large-scale climate control systems.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
