1. PRODUCT PRESENTATION

NECS-ME

Introduction

This section contains general information on the NECS-ME range of products. For detailed information refer to the speciﬁ c sections in this bulletin.

1.1 NECS-ME units

The NECS-ME chillers are a range of remote-condensation liquid units running on R410A ecological gas. They are indoor units with hermetic scroll compressors in a single-circuit (2-compressor units) and twin-circuit (4-compressor unit) tandem conﬁ guration, and braze-welded plate heat exchangers.

1.2 R410A refrigerant

The use of R410A has improved the energy efﬁ ciency of the units, in full respect of the environment (O.D.P.=0)

1.3 Combination with a remote condenser

Compact units designed for residential and commercial systems.

1.4 Integral control and adjustment

The evaporating unit is supplied complete with integral microprocessor control and optional connection to a remote con-

denser.

1.5 Hydronic unit incorporated

The integrated hydronic unit comprises the main hydraulic components; it is available in various conﬁ gurations with single or dual orthogonal pumps and high or low heads.

1.7 Ease of installation

All the connections of the NECS-ME units are located on the side in order to simplify installation operations. This feature also makes it possible to save space as the units can be positioned near the perimeter walls without compromising access to the internal components during maintenance.

1.8 Versatility

On request, the NECS-ME units can be ﬁ tted with an inte- grated pump unit for circulating the liquid in the system, with a high or low head depending on the various application requirements. As well as the primary pump, it is also possible to add an auxiliary circulation pump which starts automatically if the former develops a fault. This makes it possible to respect the harshest safety aspects of the system, whilst allowing the pumps to be rotated to balance operating hours (thus preventing risks of mechanical breakage) and to manually select one of the two pumps.

1.9 Usability

The electronic controller of the NECS-ME features a programmable menu containing the most popular European languages which the user can choose depending on the country in which the unit is used (available standard in the 4-compressor unit, in the reduced mode in the 2-compressor version).

1.6 Silent running

The NECS-ME chillers stand out for their silent running. If speciﬁ cally requested, the casing of the unit can incorporate a layer of soundprooﬁ ng made from high intermediate density conoid sandwich material which reduces noise sufﬁ ciently to allow NECS-ME to be used in residential and commercial areas without having to install it in dedicated rooms (technical rooms). The beneﬁ t in terms of noise reduction is 4dB(A) in the models with 2 compressors and 10dB(A) in the models with 4 compressors.

Minimum water content in the plant lt/kW

QuickMind is a special control unit which monitors the main operating parameters, predicts system behaviour and anticipates unit settings in order to constantly optimise performance; it allows both return and delivery water temperatures to be chosen as adjustment parameters. It can reduce outlet temperature ﬂ uctuations even with a small amount of water in the system. When, for dual-compressor chillers featuring a maximum of 12 start-ups per hour and using a traditional adjustment system, the minimum recommended water content is 5.5 l/kW. QuickMind ensures the same chiller operates correctly even with a water content of just 2.5 l/kW and considerably reduces outlet temperature ﬂ uctuations. The above graph shows that outlet temperature ﬂ uctuations with QuickMind are limited to 4.3 °C as opposed to 7.54°C if the traditional adjustment system were used, without even ensuring an acceptable minimum compressor start time.

Control unit with LCD display (optional for NECS-ME 0152..0612)

Remote keyboard

As an alternative to the standard keyboard, the NECS has a W3000 Compact operator panel with liquid crystal display. (LCD) This keyboard is standard for the NECS-ME 0604..1604 units.

This keyboard features a user interface for 3 European languages that can be selected by the user. Two of these are preset (Italian and English) and the third can be chosen from

French, German, Spanish, Swedish and Russian (to specify when ordering). This allows the control unit interface to be chosen to suit the country of destination or, thanks to English, to be completely independent for all geographical areas. This same type of operator panel is also available as a remote keyboard, to be connected to the unit by means of a serial connection up to a maximum distance of 200 metres without power supply (in this case power is supplied by the unit), or a maximum of 500 metres with dedicated local power supply.

Note

The remote keyboard may be connected to the unit without replacing the W3000 Base operator panel originally provided on the unit. In this case the interface ﬁ tted locally on the unit is ex- cluded, and access to the programming menus and the display of the machine status is present only the additional keyboard at remote level.

Instead, when the W3000 Base operator panel is replaced with the W3000 Compact panel, control of the unit is possible at both local and remote level. In this case the remote keyboard faithfully reproduces what is shown on the control unit on board the machine, further facilitating all the operations of conﬁ guring and controlling the unit.

5.2 HYDRONIC UNIT

NECS-ME

Available congurations Hydronic kit with one pump Hydronic kit with two pumps

Compact units Plug and Play.

The units in the NECS system are tted standard with a hydronic group. This houses all the main hydraulic components, thereby optimising hydraulic and electric installation space, time and cost. The innovative QuickMind control tted to the units in the NECS system, has been designed to work on systems with a low water content, offering highly professional alternatives to the installation of systems featuring storage units. For special applications, a tank to install inside the unit is available on request.

2-pole low head pump

Horizontal one-piece centrifugal pump with one impeller, axial suction and radial delivery, AISI 304L stainless steel pump body impeller. The section of the shaft in contact with the liquid is made from stainless steel. Mechanical seal made from components in ceramics/carbon/NBR/AISI304. Three phase electric motor protected to IP55, insulation class F, suitable for continuous service.

2-pole high head pump

The hydronic group in all versions of the unit can be supplied with a high head pump. In these cases, the pump features a two-pole motor even in the silent-running versions.

Water-side mechanical lter (recommended)

Y-lter designed and built to capture the impurities in the hydraulic circuit. It is tted with a 0.9 mm stainless steel mesh cartridge which can be replaced without removing the valve body from the piping.

The supply does not include the following accessories though these are recommended to ensure correct system operation:

- MA Pressure gauges upline and downline from the unit.

- GF Flexible joints on piping.

- RI On-off valves

- T Outlet control thermometer

Second pump

A second stand-by pump for high or low pressures is available on request. The pumps are automatically exchanged on the basis of a rotation programme and the stand-by pump cuts in automatically if the primary pump fails. The two-pump hydronic assembly is also tted with check valves to ensure the unit works correctly.

Special pumps

For pumps with different congurations, please contact our sales department.

10. REMOTE CONDENSERS

NECS-ME

The new Climaveneta’s remote condensers NCE type are available within three different acoustical versions:

standard version /B• low-noise version /LN• super-silenced version /SL•

All versions are available for both horizontal (H) and vertical (V) air ﬂ ow installation. The NCE remote condensers are provided with a single ventilation management. The choice of the number of circuits affects the refrigerant connections and / or the quantity of electrical signals provided to the fans speed management, according to the selected version.

Standard version (/B)

Unit equipped with 6 poles motor fan and D connections (Delta). Fan speed management based on phase cutoff control is available as option. In this conﬁ guration the units comes standard with a built-in electrical board.

Low-noise version (/LN)

Unit equipped with 6 poles motor fan and Y connections (Star). Fan speed management based on phase cutoff control is available as option. In this conﬁ guration the units comes standard

with a built-in electrical board.

Super-silenced Version SUPER-SILENZIATA (/SL)

Unit equipped with 8 poles motor fan and Y connections (Star). Fan speed management based on frequency control is available as option (inverter). In this conﬁ guration the units comes standard with a built-in the electrical board.

10.1 Electrical board

The NCE remote condensers come standard without any electrical board. The NCE are provided with a junction box which includes the electrical connections of the fans.

The electrical board is provided as standard with all the fans speed management options (phase cutoff signal and inverter control), provided with all here below listed components:

main switch• fuses on mains• system on/off light signalling• power contactor for fans on/off • control circuit transformer• protection fuses on both primary and secondary circuits • auxiliary relay for thermal protection remote signalling.•
