VRV IV W+Product code: RWEYQ-T9

Daikin RWEYQ-T9 VRV IV W+ Water Cooled Condenser 22.4kW - 50.4KW

Ideal for high rise buildings, using water as heat source

Low in refrigerant. High in performance. Ideal where space is at a premium.

Environmental conscious solution: reduced CO2 emissions thanks to the use of geothermal energy as a renewable energy source and typical lower refrigerant levels making it ideal to comply with EN378

  • No need for an external heating or cooling source when used in geothermal mode
  • Covers all thermal needs of a building via a single point of contact: accurate temperature control, ventilation, air handling units and Biddle air cutains
  • Compact & lightweight design can be stacked for maximum space saving
  • Incorporates VRV IV standards & technologies: Variable Refrigerant Temperature and full inverter compressors
  • Customize your VRV for best seasonal efficiency & comfort with the weather dependant Variable Refrigerant Temperature function. Increased seasonal efficiency and no more cold draft by supply of high outblow temperatures
  • 2-stage heat recovery: first stage between indoor units, second stage between outdoor units thanks to the storage of energy in the water circuit
  • Available in heat pump and heat recovery version
  • Variable Water Flow control option increases flexibility and control
  • Easy compliance with F-gas regulation thanks to automated refrigerant containment check
  • The ability to control each conditioned zone individually keeps VRV system running costs to an absolute minimum
  • Spread your installation cost by phased installation
  • Keep your system in top condition via our i-Net service: 24/7 monitoring for maximum efficiency, extended lifetime, immediate service support thanks to failure prediction and a clear understanding of operability and usage

Key features

Inverter

Inverter

Inverter compressors continuously adjust compressor speed to actual demand. Fewer power-consuming starts and stops result in decreased energy consumption (up to 30%) and more stable temperatures.

Variable refrigerant temperature

Variable refrigerant temperature

The intelligent systems ensures highest energy savings with additional comfort to better suit application requirements.

Daikin Watercooked VRV

Daikin Water-cooled VRV

By using water as a heat source, it achieves maximum heat recovery potential, and is ideal for high rise buildings.

Geothermal operation

Significantly reduce your CO2 emissions and take advantage of renewable energy from the ground. Our water-cooled VRV uses geothermal energy to heat and cool your building, making it ideal for BREAAM, LEED, ... certification. The ground temperature remains stable throughout the year, so this is a reliable solution for areas with extreme weather conditions.

Energy savings by 2-stage heat recovery

With a water-cooled system you achieve the maximum heat recovery potential, as all systems are interlinked with a single water loop. This heat recovery results in a higher energy efficiency and energy savings.

Invisible from the street

Engineered for indoor installations, your water-cooled VRV integrates seamlessly with your architecture and is unvisible from the street. This unit is the lightest available on the market, ideal for stacking, saving on space. Ideal for use in a floor-by-floor configuration, you lower refrigerant amounts, easily complying to EN378.

Minimum space required for technical rooms

The most compact units in the market feature a unique zero-heat dissipation principle that obviates the need for ventilation or cooling in the technical room. The room size can be reduced and no additional cooling sources are needed, giving maximum flexibility to the placement of the technical room.
