AMS 10Chapter 2 | The heat pump – the heart of the house10

An air/water-heat pump can use the outdoor air to heat up a home. The
conversion of the outdoor air's energy to residential heating occurs in
three different circuits. In the brine circuit (1), free heat energy is retrieved
from the surroundings and transported to the heat pump. The heat pump
increases the retrieved heat's low temperature to a high temperature in
the refrigerant circuit, (2). The heat is then distributed around the building
by the heating medium circuit (3).
Outdoor air
The outdoor air is sucked into the heat pump.
A
The fan then routes the air to the heat pump’s evaporator. Here, the air
releases the heating energy to the refrigerant and the air's temperature
drops. The cold air is then blown out of the heat pump.
B
Refrigerant circuit
A gas circulates in a closed system in the heat pump, a refrigerant, which
also passes the evaporator. The refrigerant has a very low boiling point. In
the evaporator the refrigerant receives the heat energy from the outdoor
air and starts to boil.
C
The gas that is produced during boiling is routed into an electrically
powered compressor. When the gas is compressed, the pressure increases
and the gas's temperature increases considerably, from 5 °C to approx. 80
°C.
D
From the compressor, gas is forced into a heat exchanger, condenser,
where it releases heat energy to the heating system in the house,
whereupon the gas is cooled and condenses to a liquid form again.
E
As the pressure is still high, the refrigerant can pass an expansion valve,
where the pressure drops so that the refrigerant returns to its original
temperature. The refrigerant has now completed a full cycle. It is routed
to the evaporator again and the process is repeated.
F
Heat medium circuit
The heat energy that the refrigerant produces in the condenser is retrieved
by the climate system's water, heating medium, which is heated to 55 °C
(supply temperature).
G
The heating medium circulates in a closed system and transports the heated
water's heating energy to the house water heater and radiators/heating
coils.
H
The temperatures are only examples and may vary between different installations and
time of year.

Contact with AMS 10
AMS 10 is controlled in various ways depending on your system. Your
contact with the heat pump takes place via SPLIT box (HBS 05) and your
indoor module (VVM) or control module (SMO). See relevant manual for
more information.
During installation, the installation engineer adjusts the necessary settings
for the heat pump in the indoor module or control module, so that the
heat pump works optimally in your system.
AMS 10Chapter 2 | The heat pump – the heart of the house12

Maintenance of AMS 10
Regular checks
Your SPLIT box only requires minimal maintenance. The condensation
hose should be checked to ensure that condensation can run out to a
drain. If there is any suspicion of leakage, pipe connections on AMS 10
should be checked.
NOTE
Insufficient oversight can cause serious damage to AMS 10 which is not
covered by the guarantee.
Checking grilles and bottom panel on AMS 10
Check that the inlet grille is not clogged by leaves, snow or anything else
regularly throughout the year.
You should be vigilant during windy conditions and/or in the event of
snow as the grilles can become blocked.
Also check that the drain holes in the bottom panel (three) are free from
dirt and leaves.
Regularly check that condensation is routed away correctly through the
condensation pipe. Ask your installer for assistance if required.

Cleaning the outer casing
If necessary the outer casing can be cleaned using a damp cloth.
Care must be exercised so that the heat pump is not scratched when
cleaning. Avoid spraying water into the grilles or the sides so that water
penetrates into AMS 10. Prevent AMS 10 coming into contact with alkaline
cleaning agents.
Silent mode
The heat pump can be set to "silent mode", which reduces the heat pump's
noise level. The function is useful when AMS 10 must be placed in noise
sensitive areas. The function should only be used for limited periods as
AMS 10 may not reach its dimensioned output.
Saving tips
Your heat pump installation produces heat and cooling and/or hot water.
This occurs via the control settings you made.
Factors that affect the energy consumption are, for example, indoor tem-
perature, hot water consumption, the insulation level of the house and
whether the house has many large window surfaces. The position of the
house, e.g. wind exposure is also an affecting factor.
Also remember:
■Open the thermostat valves completely (except in the rooms that are to
be kept cooler for various reasons, e.g. bedrooms). The thermostats slow
the flow in the heating system, which the heat pump wants to com-
pensate with increased temperatures. It then works harder and consumes
more electrical energy.
■Reduce or adjust the settings for heating in any external control systems.

Increasing the indoor temperature one degree increases power consump-
tion by approx. 5%.
Domestic electricity
In the past it has been calculated that an average Swedish household has
an approximate annual consumption of 5000 kWh domestic electri-
city/year. In today's society it is usually between 6000-12000 kWh/year.

Example: A family with 2 children live in a house with 1 flat-screen TV, 1
digital box, 1 DVD player, 1 TV games console, 2 computers, 3 stereos, 2
bulbs in the WC, 2 bulbs in the bathroom, 4 bulbs in the kitchen, 3 bulbs
outside, a washing machine, tumble drier, fridge, freezer, oven, vacuum
cleaner, engine block heater = 6240 kWh domestic electricity/year
Energy meter
Check the accommodation's energy meter regularly, preferably once a
month. This will indicate any changes in power consumption.
Newly built houses usually have twin energy meters, use the difference to
calculate your domestic electricity.
New builds
Newly built houses undergo a drying out process for a year. The house
can then consume significantly more energy than it would thereafter.
After 1-2 years the heating curve should be adjusted again, as well as the
offset heating curve and the building's thermostat valves, because the
heating system, as a rule, requires a lower temperature once the drying
process is complete.

Additional heat
The additional heat is the heat produced in addition to the heat supplied
by the compressor in your heat pump. Additional heaters can be for ex-
ample, immersion heater, electric heater, solar power system,
gas/oil/pellet/wood burner or district heating.
Ambient temperature sensor
A sensor that is located outdoors on or close to the heat pump. This sensor
tells the heat pump how hot it is where the sensor is located.
Balance temperature
The balance temperature is the outdoor temperature when the heat
pump’s stated output is equal to the building’s output requirement. This
means that the heat pump covers the whole building’s output requirement
down to this temperature.
Charge coil
A charge coil heats the domestic hot water (tap water) in the water heater
with heating water (heating medium) from AMS 10.
Charge pump
See "Circulation pump".
Circulation pump
Pump that circulates liquid in a pipe system.
Climate system
Climate systems can also be called heating systems. The building is heated
using radiators, under floor coils or convector fans.
Coil tank
A heater with a coil in it. The water in the coil heats the water in the
heater.
Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
the pressure and the temperature increase.
