VRF & VRV Air Conditioning Systems

Larger air conditioning systems are usually known as either VRV or VRF systems depending on the manufacture.

If you are looking at installing an air conditioning system with more than 4 or 5 indoor units or require heat recovery (see below) then a VRV or VRF system will usually be the recommended solution

Both systems have cooling and heating functions but some models within the range have the ability to recover either heating or cooling from one area and use it in another. For example, in winter, in a glass building with one side south-facing and the other north-facing, the people who are getting the sun may be too warm and the people in the shade too cold. Using a heat recovery system, the excess heat from the south-facing side can be used to heat the north-facing side; the opposite would occur in cooling mode in the summer. This is a cost-effective and environmentally friendly method as the heating or cooling energy that would otherwise have been wasted is instead reused in an area where additional and costly cooling or heating would otherwise have been required.

Key features of VRF systems:

• Individual Zoning: VRF allows different indoor units to operate independently, enabling individual temperature settings for various zones within a building.
• Energy Efficiency: By adjusting the refrigerant flow according to the load requirements, VRF systems can achieve significant energy savings compared to traditional fixed-speed AC systems.
• Heat Recovery: VRF systems can simultaneously cool and heat different zones within the building, making them highly efficient in managing heating and cooling demands throughout the year.
• Quiet Operation: VRF systems often operate quietly, providing a comfortable and peaceful indoor environment.

Key features of VRV systems:

• Similar to VRF, VRV systems offer individual zoning, energy efficiency, heat recovery, and quiet operation.
• Daikin's VRV brand is well-known globally and widely used in various regions.
