Basically VRF and VRV are essentially the same thing, just with different names. VRF stands for Variable Refrigerant Flow, while VRV means Variable Refrigerant Volume. The only real difference is that VRV is a brand name owned by Daikin Industries Ltd. Other companies use VRF to describe their similar systems. These systems are ideal for  large buildings and can cool or heat sizable areas efficiently.

How do they work?

These systems work by moving heat from one place to another using a special liquid called refrigerant. VRF/VRV equipment is installed as a system, with units located outdoors and indoors, inter connected by power cables, refrigerant lines and a condensate drain. The outdoor unit houses a compressor, fan, and heat exchanger. The indoor units have a heat exchanger and a fan too. The system controls the flow and temperature of the refrigerant to each indoor unit, so you can control the temperature very precisely.

What are the benefits for businesses?

VRF/VRV systems are energy-efficient and can control the temperature in different areas separately. They can heat and cool different parts of a building at the same time, which is useful and unique to VRF and VRV systems. They’re also flexible and easy to expand if needed. Plus, they can connect to smart technology for easier management.

How are they different from other systems?

VRF/VRV systems are ideal for large buildings with different, simultaneous heating and cooling needs in various areas. They’re great for places like hotels, schools, and offices where you need control over different zones.

Are there any downsides?

The main downside is the initial cost, which can be higher than other systems. They are like all air conditioning systems in that they require regular maintenance – so that’s not really a downside.

Do they need maintenance?

Yes, they need regular check-ups to keep them running smoothly. This includes cleaning filters and coils, and making sure everything is working properly. A REFCOM  registered HVAC company is required to undertake maintenance checks, as is the case with all commercial air conditioning systems.
