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 />
