VRV / VRF Systems

About VFV/VRF

VRF (Variable Refrigerant Flow) and VRV (Variable Refrigerant Volume) are innovative climate control technologies that allow for changes in temperature in different parts of a building at different times of day.

The user simply sets the ambient temperature required and the system will maintain the room at that temperature no matter what happens outside or in the next room.

With VRF/VRV technology, however, the desired temperature is set on the user control panel and the system will constantly adapt and change with the external conditions to maintain that temperature without further user interference.  It does this by ensuring that the air introduced into the room is cooled or heated to the correct temperature with the degree of cooling or heating automatically adjusted.

The Mitsui VRF air conditioning systems offer the luxury of distributed airflow and the independent control of indoor units. Installation flexibility and a wide selection of indoor unit designs and outdoor unit capacities ensure “best match” solutions for air conditioning needs, even for the most diversified requirements. Consideration for the environment during development has led to the manufacture of powerful, compact units that consume minimal energy, have a high coefficient of performance (COP) and contribute to maximum room comfort.

The occupiers of different rooms within a building may prefer their rooms a bit warmer or cooler than others.  With VRF/VRV, the ambient temperature of each room can be individually set and the system will automatically deliver air to each room heated or cooled to meet the temperature requirement, no matter what temperature users of other rooms require.

VRV / VRF Installations

VRF & VRV climate control systems have a number of benefits.

  • Small footprint. The outdoor units are very compact and can be placed close together, minimizing the space required outside your building.
  • Allows for individual adjustment of temperature in each room using simple to operate control panel
  • Systems are easy to install using small bore pipes meaning minimal disruption to building occupiers
  • Plant rooms and bulky service shafts are not required
