Hot Tips (Variable Refrigerant Flow)

VRF Has Many Advantages

Variable Refrigerant Flow (VRF) is a leading-edge, globally proven HVAC technology that can help solve many HVAC challenges. Following are a few of its merits.

  • Increased Energy Efficiency — VRF systems with inverter-driven compressors can reduce energy bills up to 25 percent.
  • Reduced Costs — While initial equipment cost can be higher, VRF’s installation and operational costs are often lower. Standard controls and simpler installation save on materials and labor.
  • Delivery of Fresh Air — With advanced filters, zoning capabilities and integration with ventilation systems, VRF can help meet indoor air mandates.
  • Limited Operational Noise — VRF eliminates disruption indoors and out. Indoor units operate as quietly as 19 decibels and outdoor units are quieter than traditional systems.
  • Variable Loads Needs — VRF does an impressive job meeting spaces’ and occupants’ needs. Full-range variable capacity delivers only the amount of conditioning required. Using integrated controls and sensors, the compressor adjusts speeds to maintain the desired zone temperature.
  • Solves Comfort Issues — VRF’s zoning offers incredibly personalized comfort control, including the ability to simultaneously cool and heat from one heat recovery system.
  • Controls Multiples Spaces — VRF can integrate with third-party software. Beyond that, VRF offers a wide variety of controls options, from individual zone controllers to centralized controllers that monitor, schedule and control multiple indoor units through a web browser.
  • Minimizes Maintenance — Little maintenance is required and doesn’t require a specialized service contractor. VRF components are easily accessible.
