2.1 General
Greenline HE is a series of heat pumps that use stored
solar energy in order to provide water-based heating and
hot water.
Fig. 1 Stored solar energy
1 Bedrock heat
2 Ground heat
3 Lake water heat
C6 - C11 are heat pumps with integrated hot water
heaters.
E6 - E17 are heat pumps designed to be supplemented
with an external hot water heater.
Once the heat pump has been installed and started,
there are a number of points that should be checked
regularly. This may concern an alarm triggering or
performing basic maintenance actions. If the problem is
repeated, you should contact the dealer.
2.2 Heat pump function
The heat pump consists of four main parts:
• Evaporator
Evaporates the refrigerant to gas and at the same time
transfers the heat from the collector to the refrigerant
circuit.
• Condenser
Condenses the gas to fluid again and transfers the
heat to the heating system.
• Expansion valve
Lowers the pressure of the refrigerant.
• Compressor
Increases the pressure of the refrigerant.
These four main parts are linked in three circuits. A
refrigerant circulates in the heat pump, which in some
parts of the circuit is in a liquid state and in other parts
in a gas state.

12 Geothermal heating coil
• The collector circuit fluid, which is a mixture of water
and anti-freeze, circulates in the borehole/geothermal
heating coil in a plastic hose. The fluid collects stored
solar energy and with the help of the collector circuit
pump leads it into the heat pump and to the
evaporator. The temperature is then approximately
0°C.
• In the evaporator, the heat transfer fluid meets the
refrigerant. The refrigerant is then in a fluid state and
is at approximately -10 °C. When the refrigerant
meets the zero degree heat transfer fluid, it starts to
boil. A vapour is formed, which is then led into the
compressor. The temperature of the vapour is 0 °C.
• The pressure of the refrigerant increases in the
compressor and the temperature of the vapour rises
to approx. +100 °C. The hot gas is then forced into the
condenser.
• In the condenser, the heat is transferred to the
house’s heating system (radiators and floor heating)
and the hot water system. The vapour is cooled and
becomes fluid. The pressure in the refrigerant is still
high when it is led on to the expansion valve.
• The refrigerant pressure is lowered in the expansion
valve. At the same time, the temperature also drops to
approximately -10 °C. When the refrigerant passes
the evaporator it changes to vapour again.
• The heat transfer fluid is led out from the heat pump
to the borehole/geothermal heating coil to collect
new stored solar energy. The temperature of the fluid
is approx. -3 °C.

Energy metering
6 720 643 415 (2010/03)
6
3 Energy metering
Energy metering in the heat pump is an approximation
based on the sum of the nominal emitted output during
the relevant metering period. The calculation requires
for example that the heat pump is correctly installed,
and that the flow and Δ temperatures on the hot and
cold sides are adjusted as recommended. The value
should therefore be regarded as an estimate of the
actual emitted output. The margin of error in the
calculation is normally put at 5-10%
In addition, the energy output is affected by the outdoor
temperature, the settings for the thermostat and room
controls and heat pump usage. Ventilation, indoor
temperature and hot water demand can play a deciding
role.
Control unit
6 720 643 415 (2010/03)
7
4 Control unit
The control unit controls and monitors the heating and
hot water production with the heat pump and additional
heat. The monitoring function shuts down the heat
pump in the event of operational disturbances so as to
prevent damage to critical parts of the pump.
4.1 Additional heat
The heat pump can be dimensioned to cover the peak
output of the house single-handedly and does not
normally need any additional heat then. Although in that
case there can be an additional heater installed solely
for emergency operation, when the heat pump is
stationary.
The heat pump can also be dimensioned to cover the
needs of the house to a somewhat lower degree and
then will need additional heat for the time of the year
when it is coldest. The additional heat also helps in the
event of emergency operation, extra hot water and hot
water peak.
The additional heat is provided through electric
additional heat.
The control unit activates automatically the additional
heat, if necessary.
4.2 Hot water production
Hot water is heated in the hot water heater and the
control unit gives priority to hot water before the heating
of heating water according to the settings that are made.
The hot water heater is fitted with a sensor that senses
the temperature of the hot water.
