4. COMPONENTS DESCRIPTION

4.1. CHILLER CIRCUIT

Compressor/s

Semi hermetic high-efficiency screw com­pressors, with a cooling capacity regulation

by means of continuous modulation from
40 to 100% (from 25 to 100% with electronic
valve) and fitted with:

− Thermal motor protection

− Oil discharge temperature check

− Electric heater for the heating of the oil

casing with the compressor at a stand­still

− Reset button.

Water side heat exchanger

Pipe bundle exchanger of the direct expan­sion type, suitably scaled to get high level
performances.
Steel housing with closed cell foam elas­tomer anticondensation mattress.
The pipe bundle is made with copper tubes,
with a special profile that allows high heat
exchange together with efficient drainage.

If so requested, the exchanger can be

fitted with an anti-freeze electrical heating
element, (ACCESSORY ONLY TO BE FITTED

IN THE FACTORY), that keeps the exchanger

from outside temperatures up to -10°C, for
the purpose of avoiding the formation of

ice in standby mode.
With the unit working, protection is assured

by the outlet water temperature probe

.

Filter drier

Of the mechanical type with cartridges,

made of ceramics and hygroscopic mate-

rial able to trap impurities and any traces of

humidity in the chiller circuit.

Sight glass

For checking the refrigerating gas load and
any humidity in the refrigerating circuit.

Thermostatic valve

In standard version, NS fi ts the thermostatic

mechanical valve, with external equaliser
on the evaporator outlet, modulates the
gas fl ow to the evaporator according
to the thermal load, in such a way as to
ensure the proper degree of overheating of
the intake gas.

- Electronic thermostatic valve

As a confi guration option, it is possible to
have the electronic thermostatic valve
for the standard models NS5002-5202­5402-5702.

Taps
Present in the liquid and discharge lines,
and allow to intercept the refrigerant in
case of extraordinary maintenance.

Solenoid valve

The valve closes when the compressor turns
off, preventing the fl ow of refrigerant gas
towards the evaporator.

Desuperheater (plate heat, optional)
(1 per parallel circuit)

Of the plate type (AISI 316), externally insu­lated with closed cell material to reduce
thermal dispersion.

Total recover (plate heat, optional)

Of the plate type (AISI 316), externally insu­lated with closed cell material to reduce
thermal dispersion.

4.2. FRAME AND FANS

over time.

Acoustic protection cover

(2)

Standard on all the NS versions, it consists
of a compartment in very thick steel sheet
and insulated entirely with soundproofi ng
material. It permits the acoustic power
emitted by the unit to be reduced and
furthermore protects the compressors from
the atmospheric agents.

4.3. HYDRAULIC COMPONENTS

Circulation pump No. 1/2 for optional
circuit configurator

Depending on the characteristics of the
pump chosen, it offers a useful head to
overcome the pressure drops in the system.
Whenever the reserve pump is present, this
is managed by the electronic board.

Expansion tank 2 per circuit (2x25 l)
(only in the versions with pump)

membrane type with nitrogen preloading.

4.4. SAFETY AND CONTROL COMPONENTS

Differential pressure switch IP54 1 per circuit

Located between the inlet and outlet of
the evaporator, it has the task of checking
that there is water circulation; otherwise,
the unit blocks.

Low pressure transducer

Allows displaying, on the microprocessor
card display, the value of the compressor's
suction pressure (one per circuit) on the
low-pressure side of the refrigerant circuit

High pressure transducer

Allows displaying, on the microprocessor
card display, the value of the compressor's
delivery pressure (one per circuit) On the
high pressure side of the refrigerant circuit

Double high pressure switch (manual + tool)

Factory-calibrated, it is placed on the high
pressure side of the cooling circuit, it shuts
down compressor operation in the case of
abnormal operating pressure.

Refrigeration circuit safety valves (HP, LP)

Calibrated at 22 bar HP - 16.5 LP, they cut
in relieving the overpressure in the case of

abnormal operating pressures.

4.5. ELECTRICAL COMPONENTS

Electrical panel

Contains the power section and the
management of the controls and safety
devices.

Door-block disconnecting switch

IT is possible to access the electrical panel
by disconnecting the voltage, then using
the opening lever of the panel itself. This
lever can be blocked with one or more
padlocks during maintenance, in order to
prevent the machine being powered up
accidentally.

4.6. ELECTRONIC REGULATION

Electronic regulation on the NS chillers
consists of control cards for each compres­sor connected to each other in a network
and a control panel with display, see figure.

In the case of models with more than one
compressor, the card that controls com­pressor 1 is the “MASTER” card, while the
others are “SLAVE”. On each card, trans­ducers, loads and alarms are connected
to the compressor that commands while
the general machine ones are connected
only on the master card. The program and
parameter pre-set are stored permanently

in the controller’s FLASH memory, to ensure
that they are kept in memory even when
the system is not powered (without the

need for an auxiliary battery).
The connection to the serial supervision as­sistance line in accordance with the RS485
standard, is performed through the serial
card ACCESSORY RS485P1 and the com-

munication protocol.

• The terminal, which is always controlled by
microprocessor, is equipped with a display,

a keypad and a set of LEDs, and is used

for programming control parameters (Set
Points, differential band, alarm threshold)

and for fundamental user operations (ON/
OFF, display controlled values).
The terminal does not need to be con-

nected to the pCO for normal controller op-

eration, and is necessary only when initially
programming the basic parameters.

− Cumulative failure block signalling

− Alarm log function

− Daily/weekly programming

− Inlet/outlet water temperature display

− Alarm display

− Full proportional regulation of the out-

put water temperature

− Programmable timer function

− Function with double setting point con-

nected to an external contact

− Fan regulation

− Interfaceability with the Modbus proto-

col (accessory)

− Pump/s control

− Compressor rotation control

− Analogue input from 4 to 20 mA

− Outside air temperature sensor

− Function "Always Woking" In the case

of critical conditions (e.g. ambient tem­perature that is too high) the machine
does not stop but is able to regulate
itself and provide the maximum power
that can be generated in those condi­tions.

− Self adapting operating differential
“Switching Histeresys” to ensure the cor-

rect compressor functioning at all times
even in plants with a low water content
or insufficient flow rates. This system
reduces the compressor wear

− The AFFP “Anti Freezing Fan Protection”

system that turns on the fans periodi­cally when the external temperatures
are very low

− The PDC “Pull Down Control” system

to prevent the activation of the power
steps when the water temperature is
approaching the set point quickly. It
optimises the operation of the machine
both when running normally or when
there are load variations, thereby
assuring top machine efficiency in all

situations.

5. ACCESSORIES

5.1. ELECTRIC REGULATION
ACCESSORIES

− AER485P1: Through this accessory,

it is possible to connect the unit with
BMS supervision systems with electri­cal standard RS 485 and MOFDBUS
type protocol

NOTE: disclosure must be provided
for compressor No. 1 .

− AERWEB30: the AERWEB device al-

lows remote control of a chiller via a
serial link from a standard PC. Using
additional modules, the device
allows to control the chiller via the
telephone network, using the AER­MODEM accessory; or via the GSM
network, using the AERMODEM GSM
accessory. AERWEB can pilot up to
9 chillers, but each of these must
be equipped with the AER485 or
AER485P1 accessory.

− MULTICHILLER: Control system to

switch the individual chillers on and
off, and command them, in a system
in which several units are installed in
parallel, always ensuring a constant
delivery to the evaporators.

− PRV3: This allows the chiller com-

mand operations to be given from a
distance.

5.2. ELECTRICAL ACCESSORIES

− RIFNS: current phase advancer.

Parallel connection with the motor
makes the reduction of input cur­rent possible. It can only be installed
when the machine is being made
and must therefore be specified
when the order is placed.

− DCPX: STANDARD for the VERSIONS:

1. SILENCED «A-E»

2. WITH DESUPERHEATER «D»

This accessory allows proper opera­tion with outdoor temperatures below
20 ° C and up to - 10 ° C. It is made
up of an electronic regulation card
that varies the fan rpm on the basis of
the condensation pressure, once the
high pressure transducer is read for
the purposes of keeping it sufficiently
high FOR the proper functioning of
the unit.

− KRS: Electric resistor exchangers for
outside temperatures down to -10 ° C

5.3. GENERAL ACCESSORIES

− GP: (TO INSTALL IN FACTORY)Pro­tects the external coil from shocks
and prevents accidental access
to the area where the compres­sors and the refrigeration circuit are
placed.

− AK: (TO INSTALL IN FACTORY)
This accessory allows additional
reduction of the noise by means of:

− Hood of the compressor optimised
by high density lead free materials
which allow further reduction of
vibrations.

− AVX (Antivibration spring) to re-
duce the transmission of vibrations
to the support structure of the unit,
consider the installation of shock
absorbers at each point of support
(see compatibility table).

8. CORRECTION FACTORS

8.1. STANDARD VERSION

8.2. STANDARD VERSION IN
SILENCED FORM

The cooling capacity yielded and the
input electrical capacity in conditions
other than rated conditions are ob­tained by multiplying the rated values
(Pc, Pa) by the respective correction
coefficients (Cf, Ca).
The following diagrams allow you to
obtain the correction coefficients to be
used for the various versions of the de­vices, in cold mode; next each curve
the external air temperature to which it
refers is shown.

KEY
Cf: correction coefficient of the

cooling capacity.

Ca: correction coefficient of the
input power.

FOR ∆t DIFFERENT FROM 5°C
Tab. 8.1.1. is used for the correction fac­tors of the cooling capacity and input
power of the water consumption.
To take into account the exchanger
soiling, apply the relative fouling fac­tors, Tab. 8.2.1.
