New Daikin Water Cooled VRV®III – Wider Range and Even More Efficient

The introduction of the new Daikin RWEYQ-P water cooled heat pump and heat recovery VRVIII extends the third generation of this highly efficient and advanced technology. New features include an individual heating and cooling changeover facility on the heat recovery option and the highest COP (6) and EER (5) ratings in the current market. A new 8HP model complements the existing 10HP model, allowing a greater range of system combinations. In addition, a further new model, designated RWEYQ-PR, is designed for application to geothermal energy projects.

Highest efficiency on the market

Water is inherently more efficient than air in storing energy and also lends itself well to sharing and recovering energy in diverse building systems, recovering renewable energy from groundwater in the case of the RWEYQ-PR range. The RWEYQ-PR is available in single unit (8 HP or 10 HP) installations and supports inlet water temperatures down to -10º C in heating mod, the relative stability of groundwater temperatures resulting in optimum system efficiency regardless of outdoor temperature.

Increased comfort

The new 8 HP outdoor unit, allows up to 9 different combinations from 8 HP to 30 HP and up to 36 indoor units can be connected, from the expanded range of 13 indoor models in 75 variations. The addition of the VRV®III BS box heat recovery unit allows heating or cooling to be selectable per indoor unit for optimal comfort. Furthermore, the RWEYQ-P can be connected to all current Daikin control systems.

Greater installation flexibility

Water cooling reduces system size and weight and increases installation flexibility due to the virtual lack of restrictions on the length and height of water piping. Refrigerant piping limits have also been increased, supporting total lengths up to 300 m. Thus, the benefits of VRV®III are now available to even taller buildings or those with installation constraints. RWEYQ-P supports inlet water temperatures from 10-45º C in both heating and cooling mod, whilst for geothermal applications the RWEYQ-PR supports inlet water temperatures down to -10°C in heating mod and in line with Daikin Europe’s ongoing environmental efforts, both systems are fully RoHS compliant.
