IT TAKES an efficient solutionYou know what your building needs. Zoned comfort, better air quality, energy efficiency, design flexibility and long-term savings. Nothing delivers them all like a Bryant Variable Refrigerant Flow (VRF) system. We utilize a 2-pipe system for both heat pump and heat recovery. Through it, you can power up to 64 independent indoor units, providing precise, energy-efficient comfort control on a zone-by-zone basis. You can cool one room while heating the other or simply provide comfort to only the zones that are in use.

WHAT IS VARIABLE REFRIGERANT FLOW (VRF)Bryant VRF systems provide precise, highly efficient comfort control. The name says it all: Variable Refrigerant Flow moves refrigerant to the specific zone that needs to be heated or cooled. Its the ultimate flexibility in HVAC: the refrigerants flow can vary from location to location, delivering just what each zone needs. No more. No less.

SIMULTANEOUS HEATING & COOLING A simplified 2-pipe design provides heat recovery and flexible refrigerant flow, Bryant VRF makes it possible to heat and cool different zones on a single refrigerant piping system at the same time. This also helps increase efficiency by capturing what would have been wasted energy from one space and returning it to the other as useful energy.

Bryant VRF Advantages

COMPRESSOR Bryant rotates the operating sequence of the outdoor units and individual compressors. By spreading the operating hours evenly, occupants can enjoy balanced, consistent comfort. Inverter-driven compressors eliminate rush currents and on/off power surges as the system adjusts to demands. They also reduce the risk of compressor failure, more common in standard non-Inverter systems. Should there be a failure, the outdoor unit provides greater backup capability, allowing the system to continue to operate and maintain comfort while the faulty compressor is isolated, repaired or addressed.

ENERGY EFFICIENT You cant build today without making energy efficiency part of the equation. Our VRF systems improve climate control and minimize energy loss by heating and cooling different rooms at the same time. They circulate the minimum amount of refrigerant necessary to satisfy the building load and each individual zone while capturing what would have been wasted energy from one space and returning it to the other as useful energy.

Coupled with that, outdoor units employ one or more Inverter-driven compressors, and each operating sequence is rotated to balance operating hours and load distribution. This means that the system operates at its most efficient range more often, providing reduced energy consumption, and a more reliable system.

AN EASIER SIMPLER INSTALLATION Our VRF systems require very little. Theres no need for distribution fans, water pumps and large hydronic pipesor space-consuming maintenance rooms or service shafts; making them easy to install, while freeing up valuable space in the building.

If youre working with a Bryant VRF specialist or become one yourself, youll find the system is easy to control. The entire system can be run from a central location.

MORE OPTIONS FOR MORE FLEXIBILITY Every building has different needs, so Bryant gives you a variety of choices. Our VRF products include a smaller equipment footprint, piping lengths up to 3280 ft. and a variety of ducted and ductless indoor unit options. Its a combination that delivers the utmost in design flexibility. Whether its a commercial or large residential application, a single- or multi-floor building, a new build or a retrofit, youll have all the options you need.

ADVANCED SILENT TECHNOLOGY WITH FAN BLADE DESIGNThe unique 3 and 4 blade fan design decrease the running noise and lowers down airflow resistance and vibration. Paired with the DC Inverter compressor, the condenser is extremely quiet with operation as low as 58.4 dB(A).

HIGH PERFORMANCE HEAT EXCHANGERThe advanced heat exchanger design enlarges the heat-exchange area, decreasing the air resistance while the hydrophilic fins and inner-threaded copper pipes optimize heat exchange efficiency.

The enhanced defrost control can adjust the defrosting cycle time based on system operating environments to reduce the time the system spends in defrost improving overall heating performance. By feeding hot gas through the bottom row of the outdoor coil we have eliminated the need for basepan heater accessories; improving system reliability.
