The Daikin VRV system is a multi-split type air conditioner for commercial buildings that uses variable refrigerant flow control developed by Daikin to provide customers with the ability to maintain individual zone control in each room and floor of a building.
Daikin VRV Advantage
Precise individual control and inverter technology minimize energy consumption to deliver optimum energy savings.
VRV systems enable individual climate control settings for each zone to provide the utmost in comfort to commercial building settings.
Modular design of outdoor units and wide selection of indoor units ensure system designs that are ideally suited to the environments where they are installed.
In addition to a maximum connection of 64 indoor units to 1 outdoor unit, large allowances for piping length and level difference provide a flexible layout.
When Daikin launched the VRV air conditioning system in 1982, it introduced the world’s first use of variable refrigerant flow control. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones. The name VRV * derives from this technology that we call “variable refrigerant volume.”
VRV System Solution
For Large-Sized Buildings
By uniting advanced software and hardware technologies for greater energy savings during actual operation and combining the technologies of VRV, VRT and VAV, we have attained both energy savings and comfortable air conditioning.
Automatic Refrigerant Charge Function
The automatic refrigerant charge function* automates the charging of the proper refrigerant amount and the closing of shut-off valves by simply pressing a switch after pre-charging. This function contributes to optimized operation efficiency, higher quality and easier installation.
The control functions of inverter technology have been integrated on printed circuit boards. As well as improving reliability, this has reduced the number of parts and enabled downsizing.
For Large-Sized Buildings
Outdoor units can operate up to 4.41 COP to reduce energy consumption.
Large Capacity and Space Saving
Outdoor units with capacities up to 56kW for a single outdoor unit and 168kW for a 3-unit combination are available. Featuring compact size and small footprint, VRV outdoor units enable space-saving and easy installation.
Increasing high static pressure for the outdoor unit fan gives greater installation flexibility.
The addition of various advanced features ensures reliable and stable system operation.
