Appliance description
brine | water heat pump as standard
appliance for internal installation.
A cascade comprising heat pumps
positioned next to or above each
other is feasible. the heat pump drive
unit is equipped with an hermetically
sealed compressor, condenser,
evaporator, safety equipment such
as a high/low pressure limiter, and
a frost protection facility. 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 b15 °C and
+60 °C. the correct and professional
implementation of the heat source
system is a must for a perfect
operation. For this, observe the heat
pump cooling load.
Sets
when the heating output of the
largest heat pump becomes
insufficient, two or more additional
heat pumps are controlled as one.
