RWEYQ-PR<br />

› Reduced CO 2 emmisions thanks to <strong>the</strong> use of geo<strong>the</strong>rmal<br />

energy as a renewable energy source<br />

› No need for an external heating or cooling source<br />

› Extended operation range (inlet water<br />

temperature) down to -10°C in heating<br />

› High heating efficiency at low water entering temperatures (eg.<br />

3.44 COP at -10°C entering water temperature for an 8HP unit)<br />

› Suitable for multi-storey and large buildings because of<br />

<strong>the</strong> hardly unlimited possibilities of water piping<br />

› Simultaneous cooling and heating operation from one system<br />

› ‘High sensible mode’: allows <strong>the</strong> <strong>VRV</strong> system to work with<br />

increased sensible capacity in cooling mode, resulting<br />

in higher efficiency and improved comfort<br />

› 2-stage heat recovery: first stage between indoor units, second stage<br />

between outdoor units thanks to <strong>the</strong> storage of energy in <strong>the</strong> water circuit<br />

› Heat recovery systems offer <strong>the</strong> highest comfort, including individual<br />

change-over of each BS box without disruption of o<strong>the</strong>r BS boxes<br />

› Wide range of indoor units: 15 different models in a total of 76 variations<br />

› Compact design (stacked configuration possible)<br />

› Connectable to current <strong>Daikin</strong> control systems: DS-net, Intelligent<br />

Touch Controller, Intelligent Manager, BACnet Gateway, DMS-iF<br />
