VRV

Why Is Daikin VRV An Efficient Alternative For Larger Commercial Buildings?

Daikin’s VRVIII system is the 7th generation of the original Daikin VRV launched in 1982. Completely re-engineered to realize opportunities for VRV in taller / larger buildings, it utilizes the latest advances in refrigeration and air-conditioning technology. The totally new Daikin Inverter compressor system delivers improved efficiency and performance, while ensuring satisfaction of demands throughout the connected zones. With a choice of 460V/3ph/60Hz or 208-230V/3ph/60Hz, the heat pump or heat recovery configurations power up to 20-Ton capacity from a single piping network. The system also allows up to 41 indoor fan coil units, a 200% connection index, and integrated controls, with BMS options and piping limitations never before seen with a DX system. With these attributes, VRVIII naturally positions itself wherever traditional chilled water systems are desired.

What is Daikin VRV?

VRV is a commercially applied heating and cooling system that distributes refrigerant, rather than water, to multiple fan coil units serving the conditional spaces. The natural attributes of a VRV system position it as an alternative to a chiller system.

The Features of Daikin VRV

  • Energy Efficent, all systems incorporate inverter “variable speed” compressors
  • Many zones (individual control – up to 41 zones on one piping network)
  • Centralized system (long piping – up to 3,280 ft. total)
  • Tight temperature control (Proportional Integral Derivative)
  • Large capacity (modular systems combination)
  • Quiet operation (down to 25db(A) indoor)
  • High level control (BACnet, LONWORKS, Intelligent Manager, Intelligent Touch Controller)
  • Superior heating performance

Why Refrigerant?

The commonly used methods of heat transfer in air-conditioning solutions each exercise different operational characteristics regarding adding or removing heat energy to a conditioned space.
The use of refrigerant reduces installation space compared to other heat transfer methods.

Why is Daikin VRV an efficient alternative?

The heating and cooling system in a commercial building is used at 70% or less of its maximum capacity for 75% of the operational time.
