Chapter 2 | The heat pump – the heart of the house
JÄSPI Inverter Nordic™
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.
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.
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.
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.
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.
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.
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).
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.
The temperatures are only examples and may vary between different installations and
time of year.

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 JÄSPI Inverter Nordic. Prevent JÄSPI Inverter Nordic coming
into contact with alkaline cleaning agents.
In event of long power cuts
In the event of prolonged power failures it is recommended that the part
of the heating system located outdoors is drained. Your installer has installed a shut off and drain valve to facilitate this. Call and ask your installer
if you are unsure.
Silent mode
The heat pump can be set to "silent mode", which reduces the heat pump's
noise level. The function is useful when JÄSPI Inverter Nordic must be
placed in noise sensitive areas. The function should only be used for limited
periods as JÄSPI Inverter Nordic 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 temperature, 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 compensate with increased temperatures. It then works harder and consumes
more electrical energy.
■ Reduce or adjust the settings for heating in any external control systems.

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 example, 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 JÄSPI Inverter Nordic.
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.
22
Chapter 5 | Glossary
JÄSPI Inverter Nordic™
Condenser
Heat exchanger where the hot gas state refrigerant condenses (cooled
and becomes a liquid) and releases heat energy to the house heating and
hot water systems.
COP
If a heat pump has COP of 5, this means that you only pay for a fifth of
your heating demand. This is the efficiency of the heat pump. This is
measured at different measurement values, e.g.: 7 / 45 where 7 stands
for the outdoor temperature and where 45 stands for how many degrees
the supply temperature is maintaining.
Disturbances in comfort
Disturbances in comfort are undesirable changes to the hot water/indoor
comfort, for example when the temperature of the hot water is too low
or if the indoor temperature is not at the desired level.
A malfunction in the heat pump can sometimes be noticed in the form of
a disturbance in comfort.
In most cases, the heat pump notes malfunctions and indicates this with
alarms in the display.
Domestic hot water
The water one showers in for example.
Double-jacketed tank
A heater with domestic hot water (tap water) is surrounded by an outer
vessel with boiler water (to the house radiators/elements). The heat pump
heats the boiler water, which in addition to going out to the all the house
radiators/elements, heats the domestic hot water in the inner vessel.
Efficiency
A measurement of how effective the heat pump is. The higher the value
is the better it is.
Electrical addition
This is electricity that, for example, an immersion heater uses as addition
during the coldest days of the year to cover the heating demand that the
heat pump cannot manage.
Evaporator
Heat exchanger where the refrigerant evaporates by retrieving heat energy
from the air which then cools.
Chapter 5 | Glossary
JÄSPI Inverter Nordic™
23
Expansion valve
Valve that reduces the pressure of the refrigerant, whereupon the temperature of the refrigerant drops.
Expansion vessel
Vessel with heating medium fluid with the task of equalising the pressure
in the heating medium system.
Fan
During heating operation, the fan transports energy from the ambient air
to the heat pump. During cooling, the fan transports energy from the heat
pump to the ambient air.
Flow pipe
The line in which the heated water is transported from the heat pump out
to the house heating system (radiators/heating coils).
Heat exchanger
Device that transfers heat energy from one medium to another without
mixing mediums. Examples of different heat exchangers are evaporators
and condensers.
Heat factor
Measurement of how much heat energy the heat pump gives off in relation
to the electric energy it needs to operate. Another term for this is COP.
Heating medium
Hot liquid, usually normal water, which is sent from the heat pump to the
house climate system and makes the accommodation warm. The heating
medium also heats the hot water.
Heating medium side
Pipes to the house’s climate system make up the heating medium side.
Pressostat
Pressure switch that triggers an alarm and/or stops the compressor if nonpermitted pressures occur in the system. A high pressure pressostat trips
if the condensing pressure is too great. A low pressure pressostat trips if
the evaporation pressure is too low.
Radiator
Another word for heating element. They must be filled with water in order
to be used with JÄSPI Inverter Nordic.
24
Chapter 5 | Glossary
JÄSPI Inverter Nordic™
Refrigerant
Substance that circulates around a closed circuit in the heat pump and
that, through pressure changes, evaporates and condenses. During evaporation, the refrigerant absorbs heating energy and when condensing
gives off heating energy.
Return pipe
The line in which the water is transported back to the heat pump from
the house heating system (radiators/heating coils).
Return temp
The temperature of the water that returns to the heat pump after releasing
the heat energy to the radiators/heating coils.
Safety valve
A valve that opens and releases a small amount of liquid if the pressure is
too high.
Shuttle valve
A valve that can send liquid in two directions. A shuttle valve that enables
liquid to be sent to the climate system, when the heat pump produces
heating for the house, and to the hot water heater, when the heat pump
produces hot water.
Silent mode
A mode where the maximum level for the output is limited to achieve a
noise reduction from the heat pump.
Supply temperature
The temperature of the heated water sent by the heat pump to the heating
system.
Water heater
