GENERAL SPECIFICATIONS

Presentation of the unit

This new series of industrial chillers and heat pumps has been designed to meet the demands of global markets in the small medium power industrial and commercial plants. Units are compact and highly configurable, built to fit different types of plants so to meet the needs of highly qualified engineers. Units are water chillers (IR) and heat pumps (IW, IP) water cooled, suitable for indoor installation; if equipped with painted structure and panels (option) they are suitable for outdoor installation too. This series is composed of 11 models and two sizes with nominal cooling capacity from 70 to 240 kW and thermal capacity from 78 to 268 kW.

The heat pump units can be supplied for commutation between "COOL- HEAT" obtained by managing the hydraulic circuit (IW units) or reversible on refrigerant side (IP units): the IP unit, compared with the IW unit, allows a reduction of installation space, a simplification of the hydraulic circuit so achieving a cheaper and quicker installation. The units produce cold water from 5 to 20°C (in cooling mode) and hot water from 25 to 55°C (in heating mode).

The units can be supplied for brine production (BR, BW, BP) that allow brine production from -10 to 5°C.

The development of the unit has mainly based on the selection of heat exchanger to obtain high efficiency at full and partial load. To increase the seasonal efficiency index (ESEER) and so further containing power input and operation cost the units can be supplied with electronic expansion valve (as standard for IP and BP units).

These features allow a compressors working with low compression ratios so increasing the reliability level and the operation life.

Great attention has been dedicated to achieve low sound levels in order to meet the increasingly restrictive laws in terms of noise: upon request, you can choose for a Standard Unit (AB) or Low noise unit (AS) or Extra low noise unit (AX). The basic unit (AB) is an essential structure made by sheet metal with anti-corrosion treatment (not painted) and without any closing panels so suitable ONLY for indoor installation, the low noise unit (AS) provides sound attenuation thanks to panels with sound absorbing insulation. The extra low noise unit (AX) provides a further sound attenuation thanks to panels with sound absorbing and acoustic jackets for compressors.

All the units are equipped with 2 scroll compressors arranged in pairs (tandem) on 1 circuit operating with

environmental friendly

R410A gas, brazed plate heat exchangers (depending on unit type completely insulated and protected on water side with a differential pressure control), electrical panel complete with electronic controller and display, phase presence and sequence control device (as standard).

As option the unit can be selected with painted structure (epoxy powders RAL 7035). For low noise (AS) and extra low noise (AX) units, the painting is extended to all closing panels, so ensuring for the electrical panel a protection degree IP54 and the maximum protection against adverse weather conditions: with this features the unit is suitable for outdoor installation (to agree with sails support department).

A variety of other accessories are available to extend the capabilities of the units. Among various the unit can be equipped with

Pumping Module (MP) with 1 or 2 pumps with Standard (STD), High (HP1) and very High (HP2) available head.

This module- full integrated inside the unit- can be asked for the water circulation on the plant exchanger, and/or for the water circulation on the source exchanger. So it is possible to order units equipped with maximum 4 pumps: max 2 for plant side, max 2 for source side.

The modules are equipped with all components necessary for a correct and easy installation so reducing the installation, space and cost for hydraulic connections.

Note that with this accessory the total length of the unit increases (see the section “dimensional data”).

The electronic controller is able to manage different condensing control systems as modulating valves (2 or 3 way, available as accessory too) or pumps driven by inverter.

Note that IW/BW units can be equipped with pumping module complete of electrical panel, but the controller is not able to manage the pumps for the 2 operation modes (cooling and heating).

The units can be coupled with dry coolers, cooling towers, geothermal probes, or uses as cooling water city water, well-water, lakewater, etc.

All units are accurately build in compliance with the existing standards and are individually tested in factory. Only electrical and hydraulic connections are required for installation.

INT - Serial interface (M/F). Allows serial communication on RS485 via MODBUS protocol

CSF - Voltage monitor and sequence meter (M). The device enables control of the correct sequence of power phases and the lack of any phase. It also ensures that the unit works within ± 10% the rated voltage (MIN=360 V - RATED=400V - MAX=440V). It blocks the unit if the voltage is outside the limits provided for.

KBT – Low temperature Kit (M). Consisting of antifreeze electrical heaters for plate heat exchangers and oil crankcase heaters for compressors. It is particularly suggested for outdoor installation or indoor installation in rooms that during winter can reach very low ambient temperature

RAM – Compressors Suction and Discharge Ball Valves (M). (not available for IP and BP units) Consisting of 2 ball valves installed on suction and discharge of the compressors: they allow an easy and quick replacement of the compressors in case of fault.

NOTES:

(M): only installed in the factory. (F): supplied for installation by the customer.

ACCESSORIES AND OPTIONAL EQUIPMENT

MP - Pumping Module (M). Consists of minimum 1 pump up to maximum 4 pumps.

The water pumps are available on 3 levels for available pressure head: Standard (STD), High Pressure (HP1), very high pressure

(HP2).

The MP is copmposed by:

1. Plant Side Pump: minimum 1 pump, maximum 2 pumps (the second pump is activated in case of failure of the first one). The pump/s is protected by magnetothermic switch installed on the unit electrical panel.

2. Source Side : minimum 1 pump, maximum 2 pumps (the second pump is activated in case of failure of the first one). The pump/s is protected by magnetothermal switch installed on the unit electrical panel.

3. Expansion tank: This is a closed, diaphragm type chamber. It absorbs the variations in the volumes of water in the system caused by temperature variations.

4 Water pressure gauge. Connected to the water fill pipe. Displays the pressure of the water in the system.

- Water safety valve, It acts whenever faulty service leads to an operating pressure in the hydraulic (set =6 bar).

- Water drain valves.

- Air vent.

EEV (M) Electronic Expansion valve (standard for IP and BP units), feeds the evaporator correctly, keeping the selected superheat degree at a steady level; it guarantees an effective and quick response to the load modifications so increasing the efficiency at partial load.

+ POMPE

SS - Soft Starter (M). Soft starter for compressors, allows a reduction around 30/40% for the inrush current and of the vibrations transmitted to the refrigerant pipes during the start-up phase.

RIF - Capacitors for power factor corrections (M). Capacitors for power factor corrections increase power factor cos φ (>0.91)

MTC - Magnetothermic switch (M). Magnetothermic switch on all loads in place of fuses.

Other power source voltage rating (contact our technical department).

Basing on design temperatures (TWE TWC) from the table “performances” extract Cooling Capacity (kWf) and Compressors Power

Input (kWa).Based on DTcond equal to the difference outlet-inlet source side exchanger (condenser) water temperature you extract

CCPF and CCPA so you can calculate

Pf = kWf x CCPF

Pass_CP = kWa x CCPA

Then you calculate the thermal power to be cooled by the source side exchanger (condenser):

Pt = Pf+Pass_CP

Then you calculate the plant side exchanger (evaporator) and source side exchanger (condenser) water flow rate :

Q_evap [l/s]=(Pf [kW]*0.86/ DTevap)/3.6:

Q_cond [l/s]=(Pt [kW]*0.86/ DTcond)/3.6:

With Q_evap you can enter on abscissa on water pressure drop graph of the plant side exchanger (evaporator) and extract pressure drop.

With Q_cond you can enter on abscissa on water pressure drop graph of the source side exchanger (condenser) city water and extract pressure drop.

Fouling factors

The performances supplied with the tables are referred to a fouling factory = 0.44x10

Basing on design temperature TWC and TWE = 7°C from the table “performances” extract Cooling Capacity (kWf) and Compressors Power Input (kWa).

Based on type and percentage of glycol extract CCPF, CCPA, CCQA, CCDP.

Then calculate.

Pf_brine = kWf x CCPF

Pass_CP_brine = kWa x CCPA

Then calculate brine flow rate:

Q_brine [l/s]=CCQA x (Pf_brine [kW]*0.86/DT_brine)/3.6 where DT_brine is the difference between inlet-outlet heat exchanger water temperature:

DT_brine=Twin_brine-Twout_brine


Finally you can calculate the actual pressure drop of the brine on heat exchanger side:

NOISE LEVEL

The noise levels refer to units operating in the nominal conditions (water temperature: inlet:

12°C - outlet: 7°C, Condenser water temperature: inlet: 30°C - outlet: 35°C).

The acoustic pressure levels are measured 1/ 5 / 10 meters away from the outer surface of the unit operating in the free field and resting on a reflecting surface (directional factor of 2).

SWL = Sound power levels, with reference to 1x10

-12

W.

The Total sound power level in dB(A) measured in compliance with ISO 9614 standards, which is therefore the only binding acoustic specification (the values of the Octave bands in the table are indicative).

SPL = Sound pressure levels, with reference to 2x10

-5

Pa.

The sound pressure levels are values calculated by applying the

ISO-3744 relation (Eu-

rovent 8/1) and refer to a distance of 1 meter away from the external surface of units operating in the open field with directivity factor 2 (Q=2) and the units operating in nominal conditions in the cooling mode.

WATER PRESSURE DROP

Applications with city water, well water

Note for the calculation of pressure drop for the Source heat exchanger using city water or well water

Unit IR

Cooling Mode

The water entering to the Source heat exchanger is at a temperature usually in the range 10.15°C. The water entering to the exchanger is controlled by a 2 way valve /ex accessory VDV) or a pump driven by inverter to have a leaving water temperature in the range 30:40°C (ΔT water in the range 15 : 20°C) : so the water flow rate is roughly 1/3 ¼ of the source water flow rate in nominal condition.

To get the pressure drop of the source heat exchanger use the diagram of this section (Source Heat Exchanger with well water)

Unità IW:

Cooling Mode

The water entering to the Source heat exchanger is at a temperature usually in the range 10.15°C. The water entering to the exchanger is controlled by a 2 way valve /ex accessory VDV) or a pump driven by inverter to have a leaving water temperature in the range 30:40°C (ΔT water in the range 15 : 20°C): so the water flow rate is roughly 1/3 ¼ of the source water flow rate in nominal condition.


Heating Mode

The water entering to the Source heat exchanger is at a temperature usually in the range 8.15°C. In this case to achieve water leaving temperature between 4 and 10°C (not dangerous for exchanger freezing) the water flow rate has to ensure a DT between 4 and 8°C: so the water flow rate is roughly the same as in nominal condition.

To get the pressure drop of the source heat exchanger use the diagram Source Heat Exchanger with Tower Water
