•  Why district cooling (For the real state developers/clients, the nation and environment).
•  The choice of condensing method for district cooling systems

Day 5: Introduction to Inlet air cooling to gas turbines

•  Iso conditions for gas turbines and nominal capacity for air conditioning units.
•  Gas turbines power output and the relation with ambient conditions and site elevation
•  Why we need to cool the inlet air to gas turbines
•  Base and peak load inlet air cooling and their economics.
• Load shifting and the need for thermal storage (Build up cycle and burn off cycle)
•  Types of thermal storage for inlet air cooling
• Open discussions on the HVAC design
• Operation and Maintenance
•  Scheduled preventive maintenance routines for DX and chilled water systems
•  Daily log sheets and the items to record and monitor.
•  Importance of pre-commissioning tests, cold and hot tests for proper maintenance
•  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.
•  Feedback from attendees and distribution of certificates
•  Continuation of open discussions on operation and maintenance

The Scandinavian Academy for Training and Development adopts the latest scientific and professional methodologies in training and human resource development, aiming to enhance the efficiency of individuals and organizations. Training programs are delivered through a comprehensive approach that includes:

• Theoretical lectures supported by PowerPoint presentations and visual materials (videos and short films).
• Scientific evaluation of participants before and after the program to measure progress and knowledge acquisition.
• Brainstorming sessions and practical role-playing to simulate real-life scenarios.
• Case studies tailored to align with the training content and participants work nature.
• Assessment tests conducted at the end of the program to evaluate the achievement of training objectives.

Each participant receives the training material (both theoretical and practical) in printed form and saved on a CD or flash drive. Detailed reports, including attendance records, final results, and overall program evaluations, are also provided.

Training materials are prepared professionally by a team of experts and specialists in various fields. At the end of the program, participants are awarded a professional attendance certificate, signed and accredited by the Scandinavian Academy for Training and Development.

Program Timings:

• 9:00 AM to 2:00 PM in Arab cities.
• 10:00 AM to 3:00 PM in European and Asian cities.

The program includes:

• A daily buffet provided during the sessions to ensure participants comfort.

Objectives

This is a specialized course concentrating on two important subjects as follows:

The details of heat load calculations, selection of appropriate equipment/system and the design of the ducts and piping networks.
After sale service including testing, commissioning, putting into commercial operation, operation and maintenance.
To have those who attend and actively participate in the discussions and case study leave the course with enough knowledge to implement their daily assignments correctly and professionally.

Who should attend

HVAC Engineers, Engineers involved in specialties such as consultants, contractors specialized engineers and end users Engineers

The Scandinavian Academy for Training and Development is committed to hosting all training programs in dedicated and well-equipped hotel facilities specifically designed for conducting and delivering training sessions, unless explicitly stated otherwise on our website. Participants will be notified of the program venue within 7 to 21 days prior to the programs start date, based on the Academys assessment and the programs circumstances. The Scandinavian Academy for Training and Development emphasizes that it holds no responsibility for any force majeure events that may prevent the program from being held at the designated venue. Nevertheless, the Scandinavian Academy for Training and Development will make every effort to provide suitable alternatives and extend the necessary support to participants in the event of a venue change due to unforeseen circumstances.
