Air Conditioning VRF & VRV

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.

Coping with External Temperature Variations

Early in the morning, no matter what the time of year, the north facing rooms of a building are likely to be quite chilly, whilst those on the south side will feel a bit warmer.  As the sun rises, the temperature inside the building will rise more quickly on the elevations facing the sun. Consequently, those rooms which do not benefit from this solar gain continue to maintain a requirement for heating at the same time that those south facing rooms need cooling.

With conventional air conditioning systems the occupiers of the building would be unable to enjoy simultaneous heating and cooling.

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 temperature of air introduced to different rooms will differ according to the conditions in that location.

Differing User Requirements

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.
