VRF Technology

Variable Refrigerant Flow (VRF) is a leading edge, globally proven HVAC technology that can help solve many HVAC challenges faced by educational facilities:

  • Increasing energy efficiency
    VRF systems with inverter-driven compressors can reduce energy bills up to 25 percent.
  • Reducing 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.
  • Delivering fresh air
    With advanced filters, zoning capabilities and integration with ventilation systems, VRF can help meet indoor air mandates.
  • Limiting operational noise
    VRF eliminates disruption indoors and out. Indoor units operate as quietly as 19 decibels and outdoor units are quieter than traditional systems.
  • Varying loads needs
    Full-range variable capacity delivers only the amount of conditioning required to match a zone’s cooling or heating demand. Using integrated controls and sensors that measure conditions within each zone, the compressor adjusts speeds to maintain the desired zone temperature.
  • Solving comfort issues
    VRF’s zoning offers personalized comfort control, including the ability to simultaneously cool and heat from one heat recovery system.
  • Controlling 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. Multiple central controllers can connect to a building management system.
  • Minimizing maintenance
    Little maintenance is required and doesn’t require a specialized service contractor. VRF components
    are easily accessible, yet also safely tucked away within the system.

  • How One School Reimagined Learning Spaces—and What Others Can Learn

    When Collegedale Academy, a PreK–8 school outside Chattanooga, Tenn., needed a new elementary building, we faced the choice that many school leaders eventually confront: repair an aging facility or reimagine what learning spaces could be. Our historic elementary school held decades of memories for families, including some who had once walked its halls as children themselves. But years of wear and the need for costly repairs made it clear that investing in the old building would only patch the problems rather than solve them.
