A variable refrigerant flow (VRF) system provides flexible installation and energy-saving cooling and heating comfort. These systems are widely considered as an alternative to traditional systems for applications where zoning or part load operation is considered necessary. Variable refrigerant flow is a system for heating and cooling spaces that is quickly gaining worldwide acceptance and popularity. Although VRF, which uses refrigerant for heating and cool spaces in either a subcooled liquid or

Over the past few years, power electronics technology has reduced VFD costs and size and increased performance through developments in semiconductor switching systems, drive topologies, simulation and control technologies, and hardware and software operation. Variable Frequency Drives (VFDs) are a green energy efficiency device that compares the amount of work or load on the engine to the amount of energy it takes to power the amount of work. It reduces the consumption of surplus energy.
