General
Usage Range
The heat pump is designed only for
heating as well as generating service
water.
The heat pump can be utilized in newly
installed or existing heating systems
by complying with the usage limits as
defined by the AQUATOP planning
document.
E
Setup
The heat pumps can be set up on a
smooth, level, and plane surface
without the need of a base or pedestal.
The installation room must be dry and
frost-free. Rooms with much humidity
such as laundry rooms, etc. are not
very suitable for installing the heat
pump. The min. clearances must be
adhered with for all equipment to
ensure access in case of maintenance
and control tasks.
Function Principle of the
Brine-Water/Water-Water Heat Pump
The heat pump converts the heat
contained in the soil or rock
(groundwater) with a low temperature
into heat with a higher temperature.
This is achieved by routing the brine
liquid through a heat exchanger in the
soil (groundwater) and a pump to the
evaporator. The liquid working medium
in the evaporator boils and evaporates
at a low temperature and low pressure.
The evaporation heat required is drawn
from the brine liquid and returned to
the heat exchanger.
The evaporated working medium is
suctioned by the compressor and
compressed to a higher pressure.
The compressed, gaseous working
medium is fed to the condenser where
it is condensed at a high pressure and
high temperature.
The condensation heat is transferred
to the heating water and the tempera-
ture of that water increases.
The energy transferred to the heating
water corresponds with the energy
previously extracted from the soil
(groundwater) plus the small amount
of electrical energy required for
compressing the working medium.
Energy-Saving Use of the Heat
Pump System
Your decision to obtain a heat pump
heating system is an important contri-
bution to saving the environment by
having lower emissions and reduce
your primary energy use.
Please observe the following points to
ensure your new heating system
functions efficiently:
L
The heat pump heating system must
be carefully dimensioned and installed.
L
Avoid unnecessarily high flow tempera-
tures. The lower the flow temperature
on the heating side the more efficient
the heat pump is working. Make sure
the controller is set correctly and
properly.
L
Rush airing (several windows open at
once for short period) is to be preferred
over continuously leaving a small gap
open. Rush airing reduces the energy
consumption.
