(3) Approximate value. The minimum capacity reached by the unit depends on the operating conditions. The value shown may not be suitable for
calculating the minimum volume of water: to do this, consult the “Minimum water content in the system” section.
(4) Unit operating at nominal operating capacity, with no options of any kind, with source-side heat exchanger input/output water temperature of
30/35°C and user-side heat exchanger water inlet/outlet temperature of 12/7°C. Binding values. Values taken by measurements made in accord
-
ance with standard ISO 3744 and the Eurovent certification programme, where applicable
(5) Values obtained from the sound power level (conditions: note 4), related to a distance of 1 m from the unit in free field with directivity factor Q=2.
Non-binding values.
(6) Unit operating at nominal operating capacity, with no options of any kind, with source-side heat exchanger input/output water temperature of
10/7°C and user-side heat exchanger water inlet-outlet temperature of 40/45°C. Values obtained from measurements carried out in accordance
with standard ISO 3744.
(7) Theoretical values referred to the basic unit (without DC). The amount of gas actually charged in the unit may differ.
(8) Reference to IS16590:2017, user-side heat exchanger outlet temperature 7 °C. Source-side heat exchanger inlet temperatures : part load 100 -
W39°C; part load 75 - W32°C; part load 50 - W26°C; part load 25 - W20°C.
(9) Reference to AHRI 550/590, user-side heat exchanger outlet temperature 6.7 °C. Source-side heat exchanger inlet temperatures : part load 100 -
W 35°C; part load 75 - W 26,7°C; part load 50 - W 18,3°C; part load 25 - W 12,8°C.
