Description
2.9. Per for mance data - cooling according to EN 14511
In order to guarantee a correct cooling mode, when working with unregulated direct-heating circles (without
cooling buffer), the following 3 requirements have to be ful
fi
lled:
1. To ensure the minimum volume of heating site, appropriate zones have to remain open all the time.
Minimum volume 80 lt.
2. To ensure the minimum
fl
ow rate of heating site, appropriate zones have to remain open all the time.
Minimum fl ow rate 1.01 m³/h
3. To ensure the minimum cooling output rate of distribution system, appropriate zones have to remain open
all the time. The minimum cooling output rate is 70 % of the minimum cooling output power of the heat-
pump at S30°C/W18°C.
Minimum cooling power consumption 2.8 kW
All 3 requirements must be ful
fi
lled independently. This is possible applying the NAVIGATOR Pro. The entire
distribution system has to ful
fi
ll the 3 mentioned requirements.
To ensure a large cooling demand, the cooling limit has to be set as high as possible.
