Modeling Variable Refrigerant Flow (VRF) Systems

In this training session the instructor uses a live example to take you through the steps for:

  • Modeling air-cooled and water-cooled VRF systems
  • Differences in ducting ventilation air to VRF indoor units or supplying ventilation independently
  • Simultaneous heating & cooling operation controls configurations
  • Modulating system performance based on piping length
  • Evaluating performance & energy results in VistaPro
Note: This training course is intended for users already familiar with Apache, ApHVAC, and VistaPro applications within the Virtual Environment.
