All HVAC systems have their own set of advantages, as well as application challenges. In this program, Trane applications engineers discuss some of the challenges when applying a variable refrigerant flow (VRF) system, such as complying with ASHRAE Standards 15 and 90.1, meeting the ventilation requirements of ASHRAE Standard 62.1, and zoning to maximize the benefit of heat recovery. In addition, the current state of modeling VRF in energy simulation software will be reviewed.

After viewing you will be able to:

  • Identify VRF system components and understand why design and installation is critical to the functionality of the system
  • Identify how controls for VRF systems differ from typical HVAC applications
  • Summarize how to comply with ASHRAE Standards 90.1 and 62.1 when using VRF
  • Summarize ASHRAE Standard 15, Safety Standard for Refrigeration Systems, requirements for VRF systems
