Information about the installation
Product information
NIBE SPLIT ACVM 270 is a complete modern heat pump
system that offers effective energy saving and reduced
carbon dioxide emissions. Climate control is safe and eco-
nomical with integrated hot water heater, immersion
heater, circulation pump and control system in the indoor
module.
The heat is retrieved from the outdoor air through an
outdoor module (AMS 10), where the refrigerant, which
circulates in a closed system, transfers the heat from the
heat source (outdoor air) to the indoor module
(ACVM 270). This eliminates the need for bore holes and
coils in the ground.

Function
NIBE SPLIT ACVM 270 is a system that can produce heating,
hot water and cooling.
The principle during heating can be simplified as follows:
1. The refrigerant in AMS 10 retrieves heat from the
outdoor air then compresses it, which increases the
temperature further.
2. The hot refrigerant (now in gas state) is routed into
ACVM 270.
3. The refrigerant releases the heat for further distribu-
tion in the system.
4. The refrigerant (now in liquid state) is routed back to
AMS 10 and the process is repeated.
By reversing the process, thereby allowing the refrigerant
in AMS 10 to retrieve the heat from the water and release
it into the outdoor air, the heat pump can, if necessary,
cool instead.
ACVM 270 determines when AMS 10 is to work and not
to work, using the collated data from the temperature
sensor. In the event of extra heat demands, ACVM 270 can
connect additional heat in the form of the internal immer-
sion heater, or any connected external addition.
