VMBMA502
The measurements are performed on a limited number of heat pumps
which can cause variations in the results. Tolerances in the measuring
methods can also cause variations.
1)
At A2W35 according to EN 14511 (including circulation pumps and
outdoor unit).
2)
At A7W35 according to EN 14511 (including circulation pumps and
outdoor unit).
3)
Heat pump with 3 kW auxiliary heater (1-N 1.5 kW).
4)
Heat pump with 6 kW auxiliary heater (1-N 3 kW).
5)
Heat pump with 9 kW auxiliary heater (1-N 4.5 kW).
6)
12 kW auxiliary heater (compressor off).
7)
15 kW auxiliary heater (compressor off).
8)
Nominal flow: heating circuit Δ10K, cooling circuit Δ3K.
9)
Pressure drop that must not be exceeded outside the heat pump with-
out the nominal flow being reduced.
10)
Sound power level (outdoor unit) measured according to EN ISO 3741.
11)
Sound pressure level calculated according to EN ISO 11203.
12)
For DHP-A, -AL models, do not use propylene glycol or ethanol.
13)
Calculated from sound power level with the assumption of a semi-
spherical propagation from a point source.
14)
12 kW auxiliary heater (compressor allowed).
15)
15 kW auxiliary heater (compressor allowed).
