Variable refrigerant flow (VRF) systems have gained a great attention and popularity in the US recent years. As building designs get sophisticated whether it was due to code and standard or design intention, a deeper understanding of system capability and limitation becomes a key to adopt and integrate VRF systems into advanced energy efficiency building designs. This seminar provides insight into system analysis and modeling techniques for different VRF system configurations. It also discusses performance evaluation of a VRF system in a laboratory environment and modeling techniques with advanced building designs, e.g., net-zero energy buildings.
