Hot Tips (HVAC)

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.
