1. General

NEPTUNE series water-cooled liquid chillers (except the condenserless

versions which are not equipped with condensers) are packaged units

with scroll compressors and a microprocessor control.

Every NEPTUNE chiller is controlled by a microprocessor named

iCHILL 200 that features from 3 capacity control steps for the units

with one cooling circuit to 6 capacity control steps for the units with

two cooling circuits. The chillers are made with IP54 protection grade,

suitable for outdoor installation. The refrigerant utilized is R407C. All

NEPTUNE series liquid chillers are made with top brand quality com-

ponents and have been designed, produced and tested in compliance

with ISO 9001:2000 standards.

2. Versions

NEPTUNE units are available in two versions:

“NE xxx” standard version, suitable for environments from

- 10 °C to 45 °C;

“NE xxx/ME” Condenserless version, suitable for environments

from - 10 °C to 45 °C.

It can also be supplied in the heat-pump version with reversible cycle

on the water side, so that the chiller can produce hot water.

The chillers has a cooling power range from 232 kW to 543 kW (at the

conditions Tin= 12 °C, Tout= 7 °C, in the evaporator and 30/35 °C in

the condenser), while the heat pump has a heating load range from

from 276 kW to 650 kW (at the conditions Tin= 12 °C, Tout= 7 °C, in

the evaporator and 40/45°C in the condenser).

Condenserless version, has a cooling power range from 232 kW to

522 kw (at the conditions Tin= 12 °C, Tout= 7 °C, in the evaporator

and 45 °C Dew).

1. Generalità

I refrigeratori di liquido della serie NEPTUNE sono unità monoblocco

condensate ad acqua (escluse le versioni motoevaporanti che non

installano i condensatori), con compressori scroll e controllo a micro-

processore. La gestione di ogni refigeratore NEPTUNE è affidata a un

controllo a microprocessore chiamato iCHILL 200 che consente la

gestione da 3 gradini di parzializzazione per le macchine a un circuito

frigo fino a 6 gradini per le macchine a due circuiti frigo. I refrigeratori

hanno un grado di protezione IP54 e quindi sono adatti per essere

installati all’esterno. Il fluido frigorigeno utilizzato è l’R407C. Tutti i

refrigeratori di liquido della serie NEPTUNE sono realizzati utilizzando

componenti di primaria marca, e sono progettati, prodotti e controllati

in conformità alle norme ISO 9001:2000.

2. Versioni

I refrigeratori NEPTUNE sono disponibili in due versioni:

“NE xxx” versione standard, adatta per ambienti da -10 °C

fino a 45 °C;

“NE xxx/ME” versione motoevaporante, adatta per ambienti

da -10 °C fino a 45 °C.

Può essere fornita inoltre, la versione in pompa di calore, ottenuta con

inversione di ciclo sul lato acqua, potendo così utilizzare le macchine

anche per produrre acqua calda.

La gamma dei refrigeratori di liquido ha un range di potenze frigorifere

che va da 232 kW a 543 kw (alle condizioni Tin= 12 °C, Tout= 7 °C,

all’evaporatore e 30/35 °C al condensatore), mentre quella delle

pompe di calore ha un range di potenze termiche che va da 276 kW a

650 kW (alle condizioni Tin= 12 °C, Tout= 7 °C, all’evaporatore e

40/45 °C al condensatore). La versione motoevaporante, ha un range

di potenze frigorifere che va da 232 kW a 522 kW (alle condizioni

Tin= 12 °C, Tout= 7 °C, all’evaporatore e 45 °C Dew).

3. Sigla

Ogni refrigeratore è identificato dalla sigla:NE XXX / ZZZ

4. Collaudo

Tutte le macchine vengono collaudate in cabine di collaudo di ampie

dimensioni e ciascun circuito viene fatto lavorare a pieno carico per

un tempo sufficiente a valutare il corretto funzionamento di tutti i

componenti.

In particolare:

• Si verifica il corretto montaggio di tutti i componenti e la mancanza

di fughe di refrigerante;

• Vengono eseguiti i test di sicurezza elettrici come prescritto dalla

EN60204;

• Si verifica il corretto funzionamento della centralina di controllo

iCHILL 200 e il valore di tutti i parametri di funzionamento;

• Si verificano le sonde di temperatura e i trasduttori di pressione;

• Si fa fluire la portata d’acqua nominale attraverso l’evaporatore e il

condensatore, si fa lavorare ciascun circuito frigorifero della macchina

in condizioni controllate (temp. uscita acqua 7 °C e temp. ingresso

condensatore = 30 °C) per verificare le temperature di evaporazione e

di condensazione, il surriscaldamento e il sottorafreddamento, la

potenza frigorifera resa, la potenza elettrica assorbita e le perdite di

carico dell’acqua attraverso l’evaporatore e il condensatore.

All’installazione le macchine richiedono solo le connessioni elettriche

ed idrauliche assicurando un alto livello di affidabilità.

Per le versioni motoevaporanti è richiesto anche il collegamento al/ai

condensatori remoti.

5. Compressori

I compressori sono di tipo ermetico scroll e presentano una serie di

vantaggi:

• una maggiore efficienza energetica (COP medio pari a 3.3)

• una sensibile riduzione del livello di pressione sonora (-6 dB(A)

rispetto ai tradizionali alternativi)

• ridotte vibrazioni

• assenza di smorzatori di vibrazioni sulla mandata dei compressori

I compressori sono dotati di motore elettrico a 2 poli protetto da un

modulo elettronico contro l’eccessiva temperatura degli avvolgimenti

dovuta ad un funzionamento anomalo, di dispositivo interno di sicu-

rezza per le sovrapressioni e di valvola di non ritorno interna sulla

mandata.

Inoltre sono montati su antivibranti in gomma e installati in un vano

acusticamente isolato con materassino fonoassorbente, chiuso da tre

pannelli di facile rimozione per qualsiasi intervento di assistenza (solo

nella versione con cuffia, il vano è isolato).

Optional

- refrigerante R22

Forniti come speciali

- rubinetti in aspirazione e mandata dei compressori.

- resistenza carter a cintura

- compressori a pistoni o compressori a vite

4. Testing

All machines are tested in large testing rooms, each circuit is tested at

full load and for a sufficient amount of time to evaluate the correct

functioning of all components.

Specifically:

• Verifying the correct assembly of all components and the absence of

refrigerant leaks;

• Electrical safety tests are performed as prescribed by the electrical

safety standard euro norm EN60204;

• Verifies that the iCHILL 200 microprocessor control is correctly ope-

rating and verifies the correctly value of all working set parameters;

• Verifies the temperature sensors and the pressure transducers;

• Setting the nominal water flow through the evaporator and the con-

denser, and operating each cooling circuit in a controlled conditions

(outlet water temperature 7 °C and ambient air temperature 30 °C )

to verify evaporating and condensing temperature, superheating and

subcooling, cooling capacity, absorbed electrical power and water

pressure drop through the evaporator and the condenser.

Unit installation requires only the electric and hydraulic connections

to be made, this will ensure a high degree of reliability.

For the condenserless versions is necessary also to connect the remota-

ble condensers.

5. Compressors

The scroll type hermetic compressors offer a number of advantages:

• a higher energy efficiency (average COP 3.3)

• a considerable reduction of the noise level (-6 dB(A) compared to

traditional reciprocating)

• reduced vibrations

• absence of mufflers on the compressors discharge

The compressors are fitted with:

• a 2 pole electric motor protected by an electronic device against

excessive part-widing temperatures caused by irregular operation

• an internal overpressure safety device

• a non-return valve on the discharge line.

The compressors are mounted on rubber anti-vibrating mountings and

installed in a sound proof insulation chamber with three easy-to-remo-

ve panels for quick service interventions (the sound proof insulation is

present only in the version with caps compressors).

lable with either single or double refrigeration circuit and one single

water circuit. These components are extremely efficient and compact,

with limited dimensions for easy installation inside the unit. The shell

is coated externally with a layer of anti-condensation insulation mate-

rial. The evaporator is protected from the low evaporating temperature

by the frost protection device of the microprocessor control which

monitors the outlet water temperature. It is also fitted with a differen-

tial pressure switch protecting the unit against water failures.

Furthermore all the evaporators used in the NEPTUNE water chillers

can work with antifreeze solutions and, generally speaking, any other

liquid compatible with the materials used for the hydraulic circuit.

All evaporators comply with CE norms.

tà. Il mantello è rivestito esternamente da uno strato isolante anticonden-

sa. L’evaporatore è protetto dal pericolo di ghiacciamento, causato da

basse temperature di evaporazione, dalla funzione antigelo della centra-

lina elettronica che ne controlla la temperatura di uscita dell’acqua.

Inoltre, ogni evaporatore monta un pressostato differenziale che lo pro-

tegge dalla mancanza di flusso d’acqua. Tutti gli evaporatori impiegati

nei refrigeratori NEPTUNE possono trattare anche soluzioni anticonge-

lanti e, in generale, altri liquidi che però non risultino essere incompati-

bili con i materiali costituenti il circuito idraulico.

E12. Control and management

The control functions are assigned to the iCHILL 200 electronic board

that is equipped with an display has 4 lines and 20 characters per line,

8 buttons to program the chiller, relative LED indicators, and an acou-

stic alarm.

The iCHILL functions are:

• evaporator outlet water temperature control according to the follo

wing modes:

- proportional

- neutral zone

- pi

•display and measure of inlet and outlet chilled water temperatures;

•Display and measure of inlet and outlet condenser (when present)

water temperatures;

•display and measure of condensing and evaporating pressures;

•automatic rotation of the starting sequence of the compressors and

the circuits to minimize the working time of each compressor;

•“Unloading” activation: it stops one or more compressor capacity

steps, resulting in reducing the heating power to the condenser

(when present, the additional effect is reducing the cooling capacity

produced). Unloading is activated when the thermal load to the con-

denser (remotable condenser for evaporating versions) is excessive

because of the an excessive inlet water temperature.

• serial interface;

Are available, a free contact for a remote general alarm and another

free contact for a remote switch ON-OFF.

Kit

• iCHILL 200 remote terminal, the similar one installed inside the

unit, up to a distance of 150 meters. The kit has a box with fixed ter-

minal of the iCHILL 200 and 3 meters of cable.

12. Controllo e gestione

Il controllo e la gestione sono affidati alla centralina iCHILL 200 che

è dotata di un display a 4 righe e 20 caratteri per riga, 8 pulsanti per la

programmazione della macchina, relativi indicatori a LED ed un avvi-

satore acustico.

La centralina consente le seguenti funzioni:

• la termostatazione sull’acqua in uscita dell’evaporatore secondo le

seguenti modalità:

- proporzionale

- zona neutra

- pi

• la misura e la visualizzazione su display delle temperature di

ingresso e di uscita dell’acqua refrigerata;

• la misura e la visualizzazione su display delle temperature di

ingresso e di uscita dell’acqua al condensatore (quando previsto);

• la misura e la visualizzazione delle pressioni di condensazione e di

evaporazione;

• la rotazione automatica della sequenza di avviamento dei

compressori e dei circuiti per minimizzare il tempo di lavoro

di ciascun compressore;

• intervento di “unloading”: vengono disinseriti uno o più gradini di

parzializzazione e in questo modo si riduce la potenza termica al

condensatore (quando previsto, come conseguenza viene ridotta

anche la potenza frigorifera prodotta). L’unloading è attivato quando

il carico termico al condensatore (condensatore remoto per le ver-

sioni motoevaporanti) è eccessivo a causa della temperatura ingresso

acqua troppo elevata.

• interfaccia seriale;

Sono disponibili, un contatto pulito per portare a distanza la segnala-

zione di un allarme generale ed un contatto pulito per l’ON/OFF

remoto.

Kit

• terminale della iCHILL 200 remotabile, simile a quello installato a

bordo macchina fino ad una distanza di 150 metri.Il kit comprende

una scatola con fissato il terminale della iCHILL 200 e 3 metri di

cavo.

Guida alla selezione

La selezione di un refrigeratore viene eseguita tramite la tabella

“Guida alla Selezione” e tramite le tabelle dati relative a ciascuna

singola macchina.

Per una corretta selezione di un refrigeratore è necessario, inoltre:

1) Verificare che siano rispettati i limiti di funzionamento indicati nella

tabella “Limiti di funzionamento”;

2) Verificare che la portata d’acqua da raffreddare sia compresa tra i

valori di portata minima e massima indicati nella tabella “Dati

Generali” di ciascuna macchina; valori di portata troppo bassa

comportano un flusso laminare e, di conseguenza, pericolo di

ghiacciamento ed una cattiva regolazione; al contrario volori di

portata troppo elevati comportano eccessive perdite di carico, e

possibiltà di rottura dell’evaporatore;

3) Prevedere l’aggiunta di glicole etilenico o di altri liquidi anticonge-

lanti per utilizzi del refrigeratore al di sotto di 3 °C di uscita acqua;

consultare la tabella “soluzioni di acqua e glicole etilenico” per

determinare la quantità di glicole etilenico necessaria e per valutare

la riduzione di resa frigorifera, l’aumento di potenza assorbita dai

compressori, l’aumento delle perdite di carico all’evaporatore a

causa della presenza del glicole etilenico;

4) Qualora la differenza di temperatura fra ingresso e uscita acqua sia

diversa da 5 °C correggere la potenza frigorifera/potenza termica e

la potenza assorbita utilizzando la tabella “Coefficienti Corretivi ∆t

≠ 5 °C”

Selection guide

For the selection of a chiller use the table “Selection Guide” and the

data tables relative to each unit.

For a correct chiller selection it is also necessary:

1) Observe the functioning limits as pointed out in the chart

“Operating Limits”;

2) To verify that the cool water flow is between minimum and

maximum values of water flow which are described in the “General

Data” table; a very low flow can cause laminar flow and thus

danger of ice formation and poor unit control; a very high flow can

cause great pressure drops and the possibility of evaporator failure

inside;

3) For working temperatures under 3 °C of water outlet it is necessary

to add ethylene glycol or any other antifreeze liquids. Consult the

chart “solutions of water and glycol” to determine the necessary

quantity of ethylene glycol, the reduction of cooling capacity, the

increase of power absorbed by the compressors, the increase of

evaporator pressure drop due to the presence of the ethylene

glycol;

4) When the difference in temperature between water inlet and outlet

is different from 5 °C, the cooling capacity/heating capacity and the

absorbed power must be connected using the table “Correction

Factors ∆t ≠ 5 °C”.

GUIDA ALL’INSTALLAZIONE - INSTALLATION GUIDE

NEP

TUN

E

37

®

L’installazione dei refrigeratori deve rispettare le seguenti indicazioni:

a) Le unità devono essere installate orizzontalmente per garantire

un corretto ritorno dell’olio ai compressori.

b) Osservare gli spazi di rispetto previsti indicati a catalogo.

c) Per quanto possibile, posizionare la macchina in modo da

minimizzare gli effetti dovuti alla rumorosità, alle vibrazioni, etc.

In particolare, installare la macchina distante, per quanto possibile,

da zone in cui il rumore del refrigeratore potrebbe risultare di

disturbo, evitare di installare il refrigeratore sotto finestre o tra due

abitazioni. Le vibrazioni trasmesse al suolo devono essere ridotte

tramite l’impiego di dispostivi antivibranti montati al di sotto della

macchina, di giunti flessibili sulle tubazioni dell’acqua e sulle

canaline che contengono i cavi di alimentazione elettrica.

d) Effettuare il collegamento elettrico della macchina consultando

sempre gli schemi elettrici forniti a corredo.

e) Effettuare il collegamento idraulico della macchina prevedendo:

- giunti antivibranti;

- valvole di intercettazione;

- sfiati nei punti più alti dell’impianto;

- drenaggi nei punti più bassi dell’impianto;

- pompa e vaso di espansione (se già non previsti nella mac china)

- filtro per l’acqua (40 mesh) in ingresso sull’evaporatore e

al condensatore.

f) Installare ,a valle dell’evaporatore, un serbatoio d’acqua se

necessario; esso serve per ridurre l’ampiezza della oscillazione

della temperatura dell’acqua refrigerata (DT) e si calcola:

Vmin = Volume serbatoio minimo (litri) =

215 x Q (kW)=

N (n°/h) ∆T (°C) NP - Vi (litri)

dove:

Q = potenza frigorifera prodotta dal chiller;

N = numero di avviamenti orari di ciascun compressore (Nmax = 10);

∆T = variazione della temperatura dell’acqua nel serbatoio (°C)

Vi = volume d’acqua contenuto in tutto il circuito idraulico (escluso

il serbatoio);

NP = numero di compressori che possono ruotare fra di loro.

g) Nel caso di potenze frigorifere richieste maggiori di quelle

massime disponibili con una sola macchina, i refrigeratori possono

essere collegati idraulicamente in parallelo, avendo cura di sceglire

unità possibilmente identiche per non creare sbilanciamenti nelle

portate d’acqua.

h) Nel caso di elevate differenze di temperatura del fluido da trattare,

i refrigeratori possono essere collegati idraulicamente in serie e

ciascun refrigeratore provvede a fornire una porzione del salto

termico dell’acqua.

i) Nel caso di necessità di trattare portate d’acqua maggiori di

quella massima consentita dal refrigeratore, è conveniente

disporre un by-pass tra ingresso e uscita dal refrigeratore.

The installation of the chiller must adhere to the following:

a) The units must be installed level to guarantee a correct return of the

oil to the compressor.

b) To observe the correct space requirements as indicated in the

overall dimensional drawings.

c) Where possible, install the chiller in a way to minimise the effects

of noise, vibration, etc. In particular, do not install the chiller in

areas where the noise can cause a nuisance as under windows or

between two residences. The vibrations transmitted to the ground

must be reduced by using anti-vibration mounts, flexible joints on

the water pipelines and on the conduit containing the cable of the

electrical supply.

d) For electrical connections, always consult the electrical drawings

enclosed with each chiller.

e) Make the chiller’s hydraulic connection as indicated:

- Anti-vibration joints;

- Shut off valves;

- Vents on the highest points of the installation;

- Drains on the lowest points of the installation;

- Pump and expansion tank (if not already included in the chiller);

- Water filter (40 mesh) on the evaporator/condenser inlet.

f) If necessary, install a water tank downstream of the evaporator. This

serves to reduce the variations in temperature of the cooled water

(∆T) and it is calculated:

Vmin = Tank minimum volume (litres) =

215 x Q (kW)=

N (n°/h) ∆T (°C) NP - Vi (litres)

where:

Q = cooling capacity

N = number of starts per hour for each compressor (Nmax = 10)

∆T= variation of the water temperature in the tank (°C);

Vi = volume of water of all hydraulic circuit (excluding the tank);

NP= number of compressors that can rotate among themselves;

g) In the case of cooling capacity greater than the maximum available

from a single unit, the chiller hydraulic system can be connected in

parallel. To avoid water flow imbalance it’s better to select the same

type of chiller.

h) When there is high temperature differences in the fluid to be

treated, the hydraulic system of the chillers can be connected in

series so each chiller provides a portion of the thermal load in the

water.

i) In the case of water flow greater than the maximum allowed by the

chiller, it is necessary to fit a by-pass between inlet and outlet of the

chiller.

l) In the event of water flow lesser than the minimum allowed by the

chiller, fit a by-pass between outlet and inlet of the chiller.

o) It is recommend to purge all air from the hydraulic system because

a small quantity of air can cause freezing in the evaporator.

p) During inactivity in winter, the hydraulic system must be discharged

or, alternatively, antifreeze must be used. Again we suggest,

specifically for brief unit stops, the use of an antifreezing heater

around evaporator/condenser and other antifreezing heaters on the

cooling circuit tubes.

l) Nel caso di necessità di trattare portate d’acqua minori di quel

la minima consentita dal refrigeratore, è conveniente disporre

un by-pass tra uscita e ingresso dal refrigeratore.

o) Si raccomanda di sfiatare accuratamente l’impianto idraulico in

quanto anche una piccola quantità d’aria può causare il con

gelamento dell’evaporatore.

p) Si raccomanda di scaricare l’impianto idraulico durante le soste

invernali o, in alternativa, di usare miscele anticongelanti.Inoltre

si consiglia, particolarmente nel caso di brevi soste, di richie

dere il refrigeratore con resistenza antigelo sull’evaporatore/conden

satore e di provvedere ad applicare altre resistenze scaldanti sulle

tubazioni del circuito idraulico.
