Note
■
Output data to EN 14511 corresponds to a tempera-
ture spread of 3 K at a brine inlet temperature of 0 °C
and brine outlet of -3 °C.
■
The specified flow rates are rounded up or down.
■
Operation as water/water heat pump with intermedi-
ate circuit:
If the brine temperature of the intermediate circuit is
reduced to 8 °C instead of 10 °C, the heat pump out-
put is reduced by approx. 5 %.
■
The specified pressure drop refers only to the inte-
gral heat exchangers in the heat pump
■
The flow rate on the primary side must not fall below
75 % of the nominal flow rate.
