VRV Changed the History of Air Conditioning
In the past, getting on a ship was the only way to travel overseas.
However, today, flying on an airplane has become the standard.
To continue Perfecting the Air, Daikin creates new standards through innovations from time to time.
“Daikin’s development of VRV”
It was the moment a new standard was created;
the birth of the next generation of air conditioners.
*VRV is a trademark of Daikin Industries, Ltd.
“Until the last person leaves, central air conditioning could not be turned off”
In the past, central air conditioning was the only way to air condition
the buildings.
Those were the days where hundreds of thousands of empty rooms around the world
were unreasonably air conditioned.
1982 VRV - The Opening of the Era of New Air Conditioning Standard
Daikin developed VRV, the world’s first
multi-split type air conditioner for commercial buildings.
The realization of individual zone control was believed to be a huge challenge,
until the arrival of VRV.
This epoch-making development has drastically innovated air conditioning standard of
commercial building.
By air conditioning only occupied rooms, VRV ensures both “energy savings” and “comfort.”

“To achieve greater energy efficiency and comfort”
1986 Lower electric bills, greater comfort level
By using an inverter that operates with enhanced precise temperature control and efficiency, VRV air conditioner greatly cuts energy costs and realizes an even more comfortable environment.
“To adapt to diverse building layouts”
1990 The outdoor unit that is installable anywhere
Daikin developed the water-cooled VRV air conditioner. VRV enabled the outside unit to be paled indoors, and now can easily be installed even in high-rise buildings.
“To respond to diverse preferences at the same time”
1990 Those who are sensitive to temperature can be satisfied together
With heat recovery VRV air conditioner, simultaneous operation of heating and cooling with one outdoor unit became possible. Daikin realized enhanced comfort to buildings with diverse air conditioning needs, such as hotels, where people gather from all around the world.
“To have replacement done easily”
1999 Surprisingly quick replacement process
Daikin developed VRV air conditioner, which can be installed just by replacing indoor and outdoor units reusing existing refrigerant piping. This development reduces the time of installation and minimizes the impact on retail businesses, which often operate 24 hours a day.
“To spread the benefits of life with VRV”
1999 Bringing coolness to extremely hot regions
Daikin has brought VRV air conditioner to where outdoor temperatures rise to 50 °C. Centering on the Middle East, Daikin has spread VRV in this hot climate region.
2007 Bringing warmth to extremely cold regions
For severely cold environments which temperatures drop as low as -25 °C, Daikin developed a highly efficient heat pump type VRV air conditioner. Daikin expanded the experience of VRV to the extremely cold regions, where combustion heating prevailed.
“To achieve ultimate comfort”
2007 Controlling even humidity
As a result of multilaterally pursuing "more
comfort", Daikin has enabled the control of humidity by VRV system
with
DESICA, heat pump desiccant.
This system has been installed also in such places as art museums and libraries,
which require precise humidity control.
What Daikin created was an ultimately new type of air conditioning.
Today, it has become one of the two types of
air conditioning systems, ducted and ductless, in the world.
Daikin will always be the pioneer of air conditioning and continue to expand this new standard, from building to building, around the world.
