VRV REPLACEMENT AIR CONDITIONING SYSTEMS FOR COMMERCIAL BUILDINGS
MODEL VRVIII-Q
For fast, cost effective replacement of existing air conditioning systems
VRVIII-Q is specifically designed for R22 replacement use. Thanks to its unique refrigerant control system, VRV III-Q can be installed using a buildings existing piping* without the need for additional special equipment or major installation work.
This ability makes it ideal for refurbishing a buildings existing air conditioning system as it can be installed quickly and easily, with minimal disruption to the building occupants. VRVIII-Q is available in either the Heat Pump or Heat Recovery series.
Cutting edge technologies to respond to the needs of larger buildings
Since the launch of the first Daikin Variable Refrigerant Volume (VRV) air conditioner in 1982, Daikin has invested heavily in research and development, leading the way in technology and air conditioning innovation. The result is a total variable refrigerant volume air conditioning solution with large outdoor capacities, simplified installation and greater energy efficiency than ever before.
1 Improved Fans and grilles
Daikin VRV III achieves a high 78.4 Pa external static pressure thanks to reduced internal pressure loss and the use of Daikin's proprietary fans and grilles. Aero spiral fan and aero asymmetrical fan: With the introduction of the VRV III range, Daikin increased the surface area of each fan blade, optimising blade design to suit each casing, reducing pressure loss for a higher external static pressure.
Aero asymmetrical fan
Daikin's 10 class (28kW) VRV III outdoor units all feature four blade, 700mm fans, for a 25% greater fan surface area than previous models
Aero spiral fan (Powerful Dual DC fan)
14 and 16 class (40 and 45 kW) VRV III units now use dual 540mm fans, increased airflow by 20% over previous models.
Aero Smooth Grille
Daikin's Aero Smooth Grille is used across the entire VRV III range. These three-dimensional, woven steel grilles are designed to facilitate smooth, low turbulence airflow. A durable fire resistant coating protects them from damage or corrosion.
2 Heat Exchanger
With a 7-10% effective length increase over previous models, the larger effective area of the heat exchanger is a key factor behind the systems high COP. Further performance gains have been achieved through the use of an optimised e-Pass heat exchanger.
3 High efficiency compressors
The key to Daikin VRV-III's high COP and larger capacity
Reluctance DC scroll compressor: Daikin's Scroll Compressors are quieter and more efficient than conventional compressors thanks to their heat-loss minimising high pressure dome construction, and the use of high pressure lubrication oil to reduce thrust losses. Combined with a high efficiency Neodymium motor, these features result in improved efficiency and reduced operating noise levels.
6 Powerful Magnets
Daikin motors use Neodymium magnets. 10 times stronger than conventional ferrite, Neodymium means Daikin motors can efficiently deliver more torque.
7 High speed
Daikin's high-performance, low-noise scroll compressor can operate at a faster rate thanks to advanced stress analysis during the design process for increased strength and oil film control in the high thrust mechanism*.
8 High Thrust Mechanism
By introducing high pressure oil, the reactive force from the fixed scroll is added to the internal force, reducing thrust losses, improving efficiency and suppressing noise.
4 Heat Transfer circuit
By sub-cooling refrigerant before expansion, the refrigerant volume required by the indoor units can be reduced without lowering the evaporation temperature. This permits the use of narrower piping for easier, less intrusive installation.
5 Compact Aero Box
By stacking inverter and control PCBs and optimising internal design for airflow speed, Daikin engineers have been able to reduce the overall size of the outdoor unit, operating noise output and power requirements for the large-diameter fanned outdoor unit.
6 Smooth Sine Wave DC Inverter
Sine wave operation results in smoother motor rotation, lowering operating noise levels and improving energy efficiency.
7 DC Fan Motor
Used across Daikin's entire VRV III range, (5-54 class (14-147 kW)), DC Fan Motors can deliver efficiency gains of up to 40% over conventional motors, especially at low speeds.
