Description And Choice Of Unit; Available Versions; Standard Equipment - AERMEC ANR Serie Manual Tecnico

The air cooled heat pumps of the ANR
series have been designed and manu-
factured to meet cooling/ heating re-
quirements and they are fit (except for
versions with incorporated accumula-
tion) for domestic hot water production
(DHW).
Machines are optimised for the heat
pump operation, by using the specific
high efficiency scroll compressor which
continues working until the outside air
temperature reaches -15 °C.
Use the chiller circuit to switch from
summer to winter use. Available in 3
sizes, the units are distinguished by an
extremely quiet operation and by a high
level of efficiency and reliability thanks
to the adoption of heat exchangers with
larger exchange surface and high per-
formance low noise scroll compressors.
Different versions are available so that a
great many different systems solutions
can be catered for.
The electrical heaters of compressors
are standard for all the models.

DESCRIPTION AND CHOICE OF UNIT

2
The ANR heat pumps can be used in:
- fan-coil / radiator panel
systems
- mixed fan-coil / radiator panel systems
thanks to their special regulation con-
trol unit for the control of the radiator
panels. An additional heater, which is
also available, allows to compensate for
the performance decline in heat pump
operation with low outside temperatu-
res, while avoiding the oversize of the
machine.
- Domestic water production is availa-
ble only for the following versions:
"H" (standard heat pump).
"HP" (heat pump only with pump).
NOTE:
For domestic hot water production
(DHW), the DCPX accessory must be
installed in the (H) versions.
