USE

HYDROCIAT LWThe HYDROCIAT LW water chillers with water cooledcondensors and screw compressors are designed for indoorinstallation and offer an optimal solution for any refrigerationapplication in the air conditioning or industrial process.

The use of HFC R134a refrigerant fluid means that the unitsrespond to the most stringent specifications forenvironmental protection, high efficiency and low electricalconsumption

The units conform to regulations EN 60.204 EN 378-2 and todirectives :- Machine (98 / 37 CEE) modified- CEM (89 / 336 CEE) modified 92/31 CEE - 93/68 CEE- Low voltage (73/23 CEE) modified 92/31 CEE - 93/68 CEE- DESP 97 / 23 CEE

HYDROCIAT LWPThe design of the water/water heat pumps range HYDROCIAT LWP is identical to that of HYDROCIAT LW.

These machines produce hot water for heating applications.

They can also be used in the cooling operation by reversingcycle on the hydraulic circuits.

HYDROCIAT LW - LW¨P

■ Compressors

■ Accessible hermetic twin screw type

■ Optimized profile of rotors ensuring a high efficiency

■ Electrical motor incorporated with part winding start

■ Integral electronic protection fo motor

■ Control of the phases balance and rotation direction

■ Integrated overpressure valve

■ Discharge temperature control

■ Lubrication under controlled pressure

■ 3-stage integrated oil separator

■ Crankcase heater

■ Thin filter at suction

■ Discharge valve

■ Slide for modulating continued output capacity control

■ Assembly on antivibration mounts

■ Integrated oil separator

■ Installed at the compressor discharge

■ The large amount of oil injected during the compression cyclenecessitates the use of an oil separator.

■ Oil, after separation from the refrigerant, is filtered beforebeing injected into the compressor.

Note :

The refrigerant oil has several important roles to ensure thesmooth running of the compressor. It :

■ Lubricates bearings and moving parts and eradicates anydirect contact between parts.

■ Ensures a secure tightness between the different mechanicalparts, thereby guaranteeing good volumetric output.

■ Cools the compressor by direct oil injection into the gasvolume being compressed.

If required, the cooling of oil allows gas discharge temperature to be limited.

■ Evaporator

■ High performance copper tubes bundle

■ Steel tubular plates

■ Steel shell

■ Corrosion resistant baffles

■ Thermal insulation with polyurethane foam

■ Water cooled condenser

■ High performance copper tubes bundle

■ Carbon steel shell

■ Carbon steel tubular plates

■ Removable cast iron headers

■ Safety valves on the refrigerant circuits

■ HPS (High Power System)

on models LW/LWP...HPS

■ The HPS system allows a significant increase in the coolingcapacity, improving the performance coefficients (EER) of yourinstallation, particulary in part load, and therefore ensuring anoptimal operation of the unit all year round.

■ Refrigerant accessories

■ Filter dryers with rechargeable cartridges

■ Liquid sight glasses

HYDROCIAT LWPThe HYDROCIAT LWP water-water heat pump range has thesame design as the HYDROCIAT LW.

The calories are taken from the natural water network (groundwater, ...) or from a water loop and are sent to the heatingnetwork through the thermodynamic circuit, instead of beingdischarged by a cooling tower or a drycooler as is the casewith the water chiller.

These water-water heat pumps can be used for cooling byreversing the cycle on the water circuits (modification of thehydraulic circuits to be made on site).

■ Diagram of therefrigerant circuitThe following refrigeration diagramdescribes an example of a CIAT unit,with desuperheater (on eachrefrigerant circuit).The heat recovery is possible only ifthe machine is running.For the same cooling or heatingcapacity, the desuperheater systemallows a free heating of hot water witha reduction of the total input power ofthe machine.

■ Principle and precautions of hydraulicconnection

To start and to run the machine under good conditions, the waterloop must be as short as possible, and the water flow of thedesuperheater must start slowly with a water flow equal to 10%of its nominal value, and must be calculated for a hot water inlettemperature of +50°C.

Thus, it is recommended to have a hydraulic diagram making itpossible to obtain hot water very quickly at the inlet of thedesuperheater (3-way valve + controller + temperature sensoron the exchanger water inlet)

The controller set point must be adjusted to +50°C minimum.

Note: particular attention must be given when selecting the expansion tank because the recovery water circuit can reach a

Check also minimum and maximum temperature differencesaccording to minimum and maximum flow (see curves on"Hydraulic characteristics" page).

CONDENSER LIMITSIMPORTANT : For the LW - LWP units to operate efficiently, particularly during start-up, itis necessary to fit a device which allows the condenser water inlet temperature to reach20°C very quickly (fitting of 3-way valves for example).

MINIMUM CHILLED WATER VOLUMESHYDROCIAT LW - LWP

A Xtra Connect microprocessor fitted on HYDROCIAT units allows a very flexible adjustment of the operation in relation to thedrift of parameters, especially for hydraulic installation with low water volume.

The auto adaptive control of the units and modulating capacity control on each compressor means that the use of the anti-shortcycle function and the installation of buffer tank is not necessary.

Minimum chilled water volumes calculation for the following conditions :

- Evaporator chilled water temperature : 12°C / 7°C

- Condenser hot water temperature : 30°C / 35°C

Note : Installations with important thermal variation or some industrial process designed to supply very constant watertemperature, should be equipped with a buffer tank.

RECOMMENDATIONS FOR ASSEMBLY

HYDROCIAT LW - LWP

■ Installation

HYDROCIAT LW - LWP are designed for indoor installation and must be protected from adverse weather andfrost.

■ A free space of 1 meter must be left all around the unit foraccess to the electrical panel and other components.

■ A free space on one side is also necessary (equal to thelength of the unit) in case one of heat exchangers needs to beremoved.

■ Sound level problems should be studied in detail. Beforeinstalling the unit, study and if necessary treat (with theassistance of a sound technicien) the various possible noisetransmissions in relation to the premises and its structure. Ifnecessary the machine should be equipped with anti-vibrationmounts and flexible connections (recommended and proposedas an option).

■ Electrical connections

All the indications necessary for the electrical connections arementioned on the electrical diagram enclosed with the unit (tobe respected).

■ These connections will be made in accordance with accepted engineering practice and conform to the regulationsin force.

■ Leave the control circuit switched on to allow operation of thecrankcase heater.

■ The electrical mains supply must be fitted with fuse or circuitbreaker protection (to be supplied by the fitter).

■ Hydraulic connections■ Water connections must be made in accordance with goodengineering practice.

■ Provide the accessories necessary for hydraulic circuits :

- Expansion vessel,

- Drain cocks at low points,

- Isolating valves,

- Air vents at high points, etc ...,

- Check that the water content in the installation is sufficient,

- Provide, if required, a buffer tank.

■ Commissioning

■ In accordance with our installation and maintenance brochure.

■ Maintenance
