A multi-split solution, VRF systems can connect up to 64 indoor units to a single modular outdoor unit system. The system calculates the refrigerant required by each indoor unit and adjusts the amount provided to the fan coil units based on the space’s operating conditions.
In other words, it controls and varies the refrigerant flow to ensure the desired comfort level of each space without over-cooling or over-heating.
VRF systems deliver incredibly efficient, zoned comfort. And, by eliminating the need for large distribution fans, water pumps and large hydronic pipes, VRF provides several installation advantages. These systems are easy-to-install and operate, without requiring dedicated maintenance rooms or service shafts, freeing up valuable real estate space in the building.
With VRF technology, heating and cooling only the spaces that need it is simple. These systems circulate the minimum amount of refrigerant needed for each individual zone to satisfy the building load. Since there are no ducts, this eliminates the energy waste associated with the duct loss.

Simultaneous Heating and Cooling
Heat recovery and flexible refrigerant flow make it possible to heat and cool different zones on a single refrigerant piping system at any given time. This also helps increase efficiency by capturing what would have been wasted energy from one space and returning it to the other space as useful energy. |

Inverter Driven Compressors
Every outdoor unit is equipped with multiple inverter-driven compressors that provide efficiency and comfort. |
 |
Reliability
The operating sequence of the individual compressors is rotated, balancing their operating hours and distributing load evenly. Inverters reduce the risk of compressor failure and eliminate on/off power surges. |

Flexibility
Carrier® now has the most diverse selection of VRF products on the market. Smaller equipment footprints matched with longer pipe lengths means there’s a VRF configuration for virtually any commercial or large residential application. VRF systems provide flexibility on reconfiguration of space for future use and can seamlessly adapt to building changes. Changing space can be easily accommodated with the different styles of indoor units without compromising the comfort level. |
 |
Comfort
The system adjusts the flow of refrigerant to each indoor unit based on its operating conditions. It computes the amount of refrigerant required by each indoor unit and controls the refrigerant flow to ensure desired comfort level without over cooling or heating of the space. |
