Principle of AGH-WPDC3 heat pump
System description 2
AGH-WPDC3 series heat pump can exploit the energy contained in natural heat sources. Or, to put it differently, the
heat pump 'collects' heat energy from the heat source.
The heat from the heat source (rock, soil, lake) is taken up via a closed collector system in which a mixture of water
and antifreeze circulates; ground water can also be used as a heat source.
The brine emits its heat to the refrigerant in the heat pump's evaporator; it then vaporizes and is compressed in the
compressor. The refrigerant, the temperature of which has now been raised, is passed to the condenser where it
gives off its energy to the heating medium circuit and, if necessary, to the water tank.
The cycle can be explained in the following stage process:
e. The heat energy released from heat carrier to water tank or radiator or floor heating systems;
a. A hose filled with liquid (brine system) is immersed into a lake, dug into the ground or sunk into the rock. The
Brine system absorbs the heat energy of the heat source so that the temperature of the water circulating in the
hose is raised a few degree;
b. The brine system is circulated to the heat pump's evaporator. Here the heat energy of the Brine system cause
the refrigerant, circulating through the evaporator, to boil and turn into a gas- it evaporates;
c. The refrigerant, having absorbed heat energy, is circulated to the compressor where pressure and temperature
are raised;
d. The refrigerant continues to go to the condenser. When condensing, it releases heat energy to the heat carrier,
circulating through the condenser. The temperature of the refrigerant sinks, and it returns to its liquid state;
f. Finally the refrigerant is led through the expansion valve, where its pressure is reduced, and then continues to go
to the evaporator, ready to start the whole circle once again.
Brine system circuit ---- a kind of mixture water (with brine) transports energy from heat source to heat pump;
Heating circuit ---- water transport heat energy to the heating system (radiators/floor coils) or the water tank.
Refrigerant circuit ---- circulates inside the heat pump, through evaporation, compression and condensation it absorbs
energy from the Brine system and releases it to the heat carrier. The refrigerant is chlorine-free;

General information for the installer
Current regulations require the heating installation to
be inspected before it is commissioned. The inspec-
tion must be carried out by a suitably qualified person
and should be documented. The above applies to
closed heating systems. If the heat pump is replaced,
the installation must be inspected again.
AGH-WPDC3seriesisplacedon a firm base,preferablya
concrete floor or foundation. Install AGH-WPDC3 series
with its back to an outside wall, ideally in a room where
noise does not matter. If this is not possible, avoid
placing it against a wall behind a bedroom or other
room where noise may be a problem. Any wall that
backs on to a bedroom should be fitted with sound
insulation. Route pipes so they are not fixed to an inter-
nal wall that backs on to a bedroom or living room.
Installation
Guideline values for collectors
Inspection of the installation
For use with 40 x 2.4 PN 6.3 PEM hose.
The length of the collector hose varies depending
on the rock /soil conditions and on the heating sys-
tem, i.e. radiators or floor heating.
Max length per collector should not exceed 400 m.
Where there is more than one collector, they must be
connected in parallel, with a means of adjusting the flow.
For surface soil heat, the hose should be buried at a
depth of about 1 metre and the distance between the
hoses should be at least 1 metres.
For several bore holes, the distance between the
holes must be at least 15m.

Overview of external structure
+

+
+
+
+
+

Factors to be taken into account when designing the
collector layout are geographical position, type of
rock/soil and cover factor of the heat pump.
When installing the collector hose ensure it rises con-
stantly towards the heat pump to avoid air pockets. If
this is not possible, install high points to vent the air.
All collector pipes in heated rooms must be insulated
against condensation. The level vessel (NK) must be
installed as the highest point in the collector system
and on the incoming pipe before the brine pump. Note
that condensation may drip from the level vessel.
Position the vessel so that this does not harm other
equipment.
As the temperature of the collector system can fall
below 0 °C it must be protected against freezing down
to -15 °C. One litre of ready mixed brine per meter of
collector hose (applies when using PEM-hose 40 x
2.4 PN 6.3) is used as a guide value when making the
volume calculation.
Details of the antifreeze used must be shown on the
level vessel.
Pipe installation must be carried out in accordance
with current norms and directives. The heat pump can
operate up to a return temperature of about 58* °C
and an outgoing temperature of about 70* °C from the
heat pump. The compressor produces up to 65* °C,
the rest is obtained using additional heating.
The other heat pumps has a max return temperature
of approximately 50 °C and an outgoing max tempera-
ture from the heat pump of approximately 60 °C.
Since the AGH-WPDC3 eries is not fitted with shut-off
valves, these must be fitted outside of the heat pump
to make future servicing easier.
During assembly the pipes for the heat medium
and water heater and possibly hot water circulation
are routed backwards. The distance between
AGH-WPDC3 series and the wall ought to be 50 mm.
General
Shut-off valves should be installed as close to the heat
pump as possible. Fit the supplied particle filter on the
incoming pipe.
In the case of connection to an open groundwater sys-
tem, an intermediate frost-protected circuit must be
provided, because of the risk of dirt and freezing in the
evaporator. This requires an additional heat exchang-
er.
Pipe connections (Brine system)
The collector circuit may be connected from the left or
from the right. The lower side panels are swapped
over to suit the chosen connection option. The
enclosed connecting pipes for the brine are secured
using the clips in the punched tabs that are folded
down on the side in question.

15 Commissioning and adjusting
Air is initially released from the hot water and venting
may be necessary. If bubbling sounds can be heard
from the heat pump, the entire system requires further
venting. When the system has stabilised (correct
pressure and all the air removed) the heating controls
can be set at the required values.
Check the fluid level in the level vessel (85). If the lev-
el has dropped, close the valve under the vessel. You
can then fill through the connection at the top of the
vessel. After filling, open the valve again.
To raise the pressure, close the valve on the incoming
main pipe when the brine pump (KBP) is running and
the level vessel (NK) is open, so that water is drawn in
from the vessel.
The siphon principle is used to empty the water
heater. This can be done either via the drain valve on
the incoming cold water pipe or by inserting a hose
into the cold water connection.

1). Read the brine temperatures on the panel. The dif-
ference between these two temperatures should
be 2—5 °C when the system has come into bal-
ance. Adjust the flow with the knob on the brine
pump (32). A high difference indicates a low brine
flow. A low difference indicates a high brine flow.
2). Check the flow temperature and the return
return temperature on the panel. The difference
between these two temperatures, with floating
condensing, should be 5 — 10 °C when the house
is being heated without additional heat. Adjust the
flow with the knob on the heating medium pump
(37). A high difference could depend on a low heat
medium flow. A low difference indicates a high
heat medium flow.

described in detail further down.
To be able to select the desired menu and increase or reduce preset values, you will use the five buttons.
Symbols
For you to know at a glance the actual operating mode of the heat pump, one of the following symbols will be shown in the lower
part of the display depending on which part of the unit is working:
The heat pump is running.
The auxiliary heater is activated.
The figur e next to the symbol indicates
capacity step.
There is a room heating demand.

When this symbol appears, the heat pump
is not running due to external signal stop it;
heat pump will restore running as soon as
signal input again
When this symbol appears, the
compressor was not running due to
high pressure of refrigerant system;
the compressor will be stopped as soon
as water temperature over 50 °C and
refrigerant system pressure over 4.0MPA,
electrical heater will start as supplementary;
compressor will restores as soon as water
temperature less than 50 °C and refrigerant
pressure get right.
During heat pump running, if the water tank symbol twinkles once in every second, it means water tank
temperature is too low and it is in antifreezing protection. At the time warm water heating will forcibly start until
water temperature get to 20 ć, then go back to previous running mode.

the slope—two points decide one beeline, point one is (0,40), the other point could be (18,24), the point
(18,24) is not changing when changing the slope, because factory setting is that heat pump stops when
outdoor ambient temperature is 18ć, so the feed water temperature should be 24ć.
