Variable Refrigerant Flow Systems:
Design & Applications (MENA)
One-Day Intensive Training · 6 Hours · 6 PDH
In association with ASHRAE Global Training Center, UAE
Deadline: 05 October 2026
About the Course
This course is designed for a global audience, specifically attendees in the Middle East, North Africa, and Asia. It provides a comprehensive overview of Variable Refrigerant Flow (VRF) technology, including equipment and system types, heating/cooling operation, heat recovery, and the benefits of VRF systems.
Also covered is the complete VRF design process: load profile analysis, unit sizing, ventilation air strategy, refrigerant piping design, and system monitoring and controls. Refrigerant safety considerations are explained, including a discussion of ASHRAE Standards 15 and 34. The course concludes with a focus on human comfort and sustainable design, featuring example buildings, ventilation systems, and VRF system layouts.
