VVM 320 - An excellent choice
The indoor module can be connected to an optional low temperature
heat distribution system, e.g. radiators, convectors or underfloor heating.
It is also prepared for connection to a number of different products and
accessories, e.g. solar or other external heat source, extra water heater,
swimming pool and climate systems with different temperatures.
VVM 320 is equipped with a control computer for good comfort, good
economy and safe operation. Clear information about status, operating
time and all temperatures in the system is shown on the large and easy to
read display. This means, for example, that external unit thermometers
are not necessary.
Excellent properties for VVM 320:
■Water heater
There is a water heater integrated in VVM 320, which is insulated with
environmentally friendly cellular plastic for minimal heat loss.
■Buffer vessel
There is a buffer vessel integrated in the indoor module that equalises
the temperature of the water that is sent out in the climate system.
■Scheduling the indoor comfort and hot water
Heating and hot water can be scheduled for each day of the week or
for longer periods (vacation).
■Large display with user instructions
The indoor module has a large display with easy-to-understand menus
that facilitate setting a comfortable climate.
■Simple troubleshooting
In the event of a fault, the indoor module display shows what happened
and the actions to be taken.
■External heat source
VVM 320 is prepared for easy connection to oil/gas/ wood fired boiler
or district heating.

9NIBE™ VVM 320Chapter 2 | The heating installation – the heart of the
house

Installation function
An air/water-heat pump installation exploits outdoor air to heat up accom-
modation. The conversion of the outdoor air's energy to accommodation
heating occurs in three different circuits. *From the outdoor air, (1) , free
heat energy is retrieved and transported to the heat pump. In the refriger-
ant circuit, (2) the heat pump increases the retrieved heat's low temper-
ature to a high temperature. In the heating medium circuit, (3) the heat
is distributed around the house.
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 0 °C to approx 80
°C.
D
From the compressor, gas is forced into a heat exchanger, condenser,
where it releases heat energy to the indoor module, 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 indoor module's water, the 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 heat energy to the house radiators/heating coils.
H
The temperatures are only examples and may vary between different installations and
time of year.

External information
When the indoor module door is closed, information can be received via
an information window and a status lamp.
Information window
Status lamp
Information window
The information window shows part of the display that is on the display
unit (located behind the door to the indoor module). The information
window can display different types of information, e.g. temperatures,
clock, etc.
You determine what is to be displayed in the information window. Your
own combination of information is entered using the display unit. This
information is specific to the information window and disappears when
the front hatch of the indoor module door is opened.
Instructions on how to set the information window can be found on page
60.
Status lamp
The status lamp indicates the status of the indoor module: continuous
green light during normal function, continuous yellow light during activ-
ated emergency mode or continuous red light in the event of a deployed
alarm.
Alarm management is described on page 68.
