Appliance description
water | water heat pump for internal
installation of a set combination. the
heat pump drive unit is equipped
with an hermetically sealed
compressor, soft starter, condenser,
evaporator (made completely from
stainless steel), safety equipment
such as a high/low pressure limiter,
and a frost protection facility.
the stainless steel evaporator is
corrosion-resistant to all types of
groundwater that contain no more
than 300 mg/l chloride and 0.5 mg/l
free chlorine. the heat pump is filled
with HCFC and CFC-free refrigerant
r410A.
Function
environmental energy is extracted
by the heat exchanger on the heat
source side (evaporator). Any energy
extracted is transferred, together with
the energy drawn by the compressor
drive, to the heating water by a
heat exchanger on the heating
water side (condenser). subject
to the heating load, the heating
water can be heated to between
+15 °C and +60 °C. the correct and
professional implementation of the
heat source system is a must for
a perfect operation. implement a
well installation in accordance with
the technical documentation and
manufacturer's details.
Sets
when the heating output of the
largest heat pump is inadequate, two
wPw M heat pumps are controlled as
set 20 to 36.
