VRF air conditioning systems – why are they so efficient?

VRF air conditioning systems

Well there’s a clue in the title…Variable Refrigerant Flow (VRF) or Variable Refrigerant Volume (VRV) air conditioning technology, used in commercial buildings, achieves extremely high efficiencies by varying the flow of refrigerant to the indoor units based on the exact demands of the individual areas.

In its simplest form a single VRF outdoor unit serves multiple indoor units, which are connected to it via copper pipe work containing refrigerant. The rooms or zones within the building will very often need to operate at differing temperatures throughout the day. Typically, changes in outdoor temperature, solar gains, varying occupancy, office equipment and lighting mean that some areas of the building require cooling, while simultaneously, other areas will require heating, to maintain a constant and comfortable internal environment.

A well-designed VRF air conditioning system will redistribute excess heat from areas that require cooling to those that require heating. These heat recovery VRF systems deliver the ultimate in energy efficiencies, achieving a SCOP/SEER in excess of 5.0. In layman’s terms this means you get 5 kW of heating or cooling for every 1 kW of electricity that is consumed – five times more efficient than a regular electric heater.

Additionally, being flexible and modular in design, multiple outdoor units can be joined together to increase the overall system capacity. Indoor units come in numerous types and sizes making them suitable for most applications. Systems can also be engineered to minimize or even totally remove the requirement for air distribution ductwork, making them cost effective to implement and easier to install where there is limited space.

Sophisticated controls enable the system to be optimised and allow users complete control over their local environment, with no adverse impact on other areas served by the same system. These controls can also be easily integrated into the buildings BEMS control system as required.

Key benefits of VRF air conditioning systems:

  • Highly energy efficient (lower operating costs)
  • Precise temperature control & zone comfort
  • Simultaneous heating & cooling
  • Heat recovery
  • Great flexibility
  • Simpler to install
  • Sophisticated, user-friendly controls
