Conference Center | Kuwait City, Kuwait
Sunday, November 26, 2023 | 9:00 AM – 4:00 PM Kuwait

This training is conducted alongside ASHRAE’s Eighth International Conference on Energy Research and Development (ICERD_8) topical conference. Registrations to the courses only, are done through Kuwait Society of Engineers.


The VRF training offered by the ASHRAE Global Training Center provides in-depth training of VRF technology, including equipment and system types, heating/cooling operation, heat recovery, and the benefits of variable refrigerant flow (VRF) systems customized for the Middle East & Northern Africa practitioners. The training focuses on the VRF design process, including load profile, analysis, and ventilation air strategy. Among other course features is a review of refrigerant piping design, unit sizing, and system monitoring/controls.

The training covers a review of ASHRAE Standard 15 “Safety Standard for Refrigeration Systems and Designation and Classification of Refrigerants,” the industry reference to ensure the safe design, construction, installation and operation of refrigeration and air conditioning systems by establishing specific safety requirements. Applying Standard 15 to VRF systems is accomplished by reviewing three basic sorting classification: occupancy, system, and refrigerant.

The training explains the step-by-step approach to ensure that the VRF system design follows the safety requirements of Standard 15. The course concludes with a focus on human comfort and sustainable design featuring example buildings, ventilation systems, and VRF system layouts.

Course Objectives:

  • Provide an overview of variable refrigerant flow (VRF) system technology, theory, and operation.
  • Discuss consideration for design and application of VRF systems in buildings.
  • Describe applicability of ASHRAE Standard 15, Safety Standard for Refrigeration Systems, requirements to VRF systems.
  • Review application of VRF systems in different building types.
