Effective energy management in smart buildings using VRV/VRF systems

A new kind of HVAC system is emerging in the building space conditioning market for commercial buildings. This new technology is based on variable refrigerant flow (VRF) or variable refrigerant volume (VRV) technology, which increases effectiveness and efficiency, but these systems are considered new as they have been in existence for only a little over a decade. So these constant improvements and technological upgrades have always kept consumers guessing what new upgrade would be launched and when. This chapter contains a brief discussion of the performance analysis and energy-saving potentials of air conditioning systems with VRV and VRF systems. The initialism VRV can be expanded as variable refrigerant volume, the title that was patented by Daikin. Other brands refer to the system as VRF – variable refrigerant flow. This chapter offers an exploration of the insights, implementation, and the benefits of this system.. For example, through this technology we can make temperature variations in autonomous rooms based on indoor occupancy rates as this technology blends several separate units into one, thereby providing a centralized service. In these systems, during the peak time cycle, compressor power usage can be greatly decreased, and energy bills can be reduced. Due to the potential for energy savings of the VRF system, the downside found in the VRF system is the high initial cost relative to traditional air conditioning systems, so economic VRV/VRF technological systems do need to be built in order to improve business potential and energy quality.
