2 DESCRIPTION AND CHOICE OF UNIT
2.1.1 STANDARD EQUIPMENT
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.
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.

Compressor
High-efficiency, scroll-type compressors fitted
on shock absorbers operated by a two-pole
electric motor with internal thermal protec-
tion;
Supplied with an antifreeze electric heater,
automatically powered when the unit pau-
ses, so that the unit is kept powered up.
Air side heat exchanger (coil)
Made with copper pipes and aluminium fins
locked into place by means of mechanical
expansion of the pipes. With a protection
grille.
Water side heat exchanger (plate type)
of the plate type, it is insulated externally
with closed cell material to reduce thermal
dispersions.
Filter drier
Of the mechanical type made of ceramics
and hygroscopic material able to trap impuri-
ties and any traces of humidity in the cooling
circuit.
Thermostatic valve
The mechanical type valve with outside equa-
liser on the evaporator outlet modulates the
gas flow to the evaporator dependent on the
thermal load in such a way as to ensure the
proper intake gas degree of overheating.
HOT GAS INJECTION solenoid valve (only for
heat pumps.)
The valve placed between the compressor de-
livery and thermostatic valve outlet controls:
- Defrosting cycle without cycle reversing
- Safety capacity control if pressure increa-
ses

Placed on the high pressure side of the refri-
geration circuit, it communicates to the con-
trol card the operating pressure, sending a
pre-alarm in case of abnormal pressure.
DCPX
standard in versions (HP)
The standard units are not suitable for
being installed in a salty environment. The
minimum and maximum limits for water flow
speed to the heat exchanger are indicated by
the curves shown in the diagrams related to
pressure drop. For information about opera-
ting limits, consult the diagrams below, which
are valid if ∆t = 5 °C.
WARNING:
- To use the machine beyond the limits indi-
cated in the diagram, contact AERMEC engi-
neering department.
- If the machine is placed in a windy area,
install an adequate wind break to avoid the
DCPX device to operate in an unstable con-
dition.
4.5 ELECTRICAL COMPONENTS
Electrical panel
Contains the power section and the mana-
gement of the controls and safety devices.
This conforms with standard CEI 60204-1,
and electromagnetic compatibility directives
EMC 89/336/EEC and 92/31/EEC.
Door lock knife switch
THE electrical panel can only be accessed
by cutting off power using the opening lever
on the panel itself. This lever can be locked
in place using one or more padlocks, during
maintenance in order to prevent the machi-
ne from being powered up accidentally.

5 ACCESSORIES
PR3 - simplified remote control panel
It allows basic machine controls to be
performed (turning on / off, changing
function mode, summary of alarms). The
maximum installation distance allowed is
150 m with a six-pole cable (cooling-only
version) or seven-pole cable (heat pump
versions) plus shielding, with minimum
cross section of 0.5 mm.
VT – Shock absorbers.

4.6 MODU CONTROL ELECTRONIC
ADJUSTME
Modu_Control
- Outlet water temperature control with
proportional-integral algorithm: it keeps
outlet medium temperature to the value
set
- Self adapting start-up differential: it
guarantees the minimum time of com-
pressor operation in systems with low
content of water
- Intelligent defrosting for pressure decre-
ase: it allows to determine when the coil
is actually defrosted by avoiding useless
defrosting
- Defrosting by hot gas injection it con-
sumes less energy, increasing heating
capacity, efficiency and preventing tem-
perature decrease in terminals (it is very
important in systems with low content
of water)
- Emergency defrosting with cycle rever-
sing: to overcome the most demanding
conditions
- Compensation of set-point with out-
side temperature (with an additional
ambient air probe): it reduces energy
consumption
- Condensation control based on pressure
instead of temperature, for a total stabi-
lity (with additional rpm regulator)
- Reverse condensation control for opera-
tion with heat pump also during sum-
