In this advanced course on Variable Refrigerant Flow (VRF) Troubleshooting we will explore the troubleshooting tasks of a VRF system. This system consists of three multiple units: Outdoor Unit Indoor Unit and Mode Selector Box. All together these units work together to complete the heating and cooling processes needed within the areas of commercial buildings. With each scenario you will be guided with simulation based steps to check for key signs of different faults through error codes electrical measurements and visual inspections. You will also utilize procedures for repairing parts replacing components and maintaining the VRF system.

In this course we'll learn about calculating electrical transformer loads to ensure the safe and efficient distribution of electricity. We'll first understand about how load results help adjust electrical distribution and voltage at every stage of the grid. We'll also learn how load results help select the appropriate transformer equipment wiring and overcurrent protection. Next we'll discuss the differences and characteristics between single and three-phase transformers. Finally we'll familiarize ourselves with commonly used calculations for sizing electrical transformers and overcurrent protection based on electrical codes and tables provided by the National Electric Code or the NEC.
