Variable Refrigerant Flow (VFR) and Variable Refrigerant Temperature (VRT)
Thomasena Philen, Daikin AC
Variable Refrigerant Flow (VRF) is the wave of the future. How can the industry improve on this leading edge
technology, by combining VRF with Variable Refrigerant Temperature (VRT). This session will discuss the
basics of VRF & inverter technology and how it is typically applied and then expand on how Variable
Refrigerant Temperature can improve on overall system efficiency. VRT is a commercial cooling & heating
application. Instructors teaching VRT technology in the classroom will be building upon a solid foundation of
the refrigeration cycle and how it looks on a P&E chart as well as applying the concepts to system design.
