General notes
The module active cooling allows you to operate your heat pump heating unit also with a cooling function in addition to
the known hot and warm water preparation functions. These cooling function enables the cooling of the building in
relation with an appropriate distribution system when it is operated in summer.
Since the module active cooling is based on the use of a cooling circuit of the heat pump there is a possibility of cooling
also at increased outside and earth temperatures.
Operation
The heat pump module active cooling is based on the reversibly designed refrigerating circuit which is integrated in the
heat pump basic unit, i.e. the heat pump is working in reverse operation. In this way it is possible to cool the heating
water in summer by means of a heat pump. The living rooms are cooled down and the ground is heated up.
Since the module active cooling is based on the use of the heat pump compressor the accruing power consumption is
comparable to the power consumption during the heating period.
Proper use
The module active cooling is an optional module for the upgrading of your heat pump device during production at the
factory. The indications for the following heat pumps are binding:
bravour serie:
BW(i)/ WW(i)
The bravour module active cooling represents a firmly combined unit together
with the bravour heat pump.
The manufacturer cannot be held liable for damages and malfunctions which can
be traced back to non-observance of the operating and installation instructions.
It is necessary to install safety devices. Please request any further information at
the service hotline: +49 3843 / 2279-111.
Planning and dimensioning
For planning and dimensioning of heating and cooling spaces consider the common technical rules.
For maximum transferable cooling capacity it can be calculated with 100 W/m
2
for wall and sealing spaces. For under-
floor spaces, which are used for cooling, lower transferring capacities should be considered – at maximum 20 … 25
W/m
2
. The surface of the floor is only suitable in lower rate for cooling a building. Important for the optimum heat
transfer is the counter-flow principle
inside the heat exchangers.
Remark: During cooling operation the relative humidity of the air is raising. This may lead to undershooting the dew
point temperature and therefore condensing of water at the cooled spaces. If the condensing takes place at the surface
or inside of the walls, there is the danger of damages by mildew.
Please consider that the room temperatur should not be lower than 6 K below
outside air temperature with respect to health!
