Design code

No. of compressor

CompressorsSemi-hermetic screw compressors specifically designed for low temperature application. The compressor has 2 five

and six-lobe rotors: the five-lobe rotor is splined directly onto the motor without any interposed overgears. The use of

two rotors permits elevated volumetric output, uniform gas flow without jerks, reduced vibrations and dimensions. The

bearings provided along the rotor axis, in a separate chamber isolated from the compression chamber, are in high-

strenght carbon steel. Oil flow managed by pressure’s differences, without any dedicated oil pump, specifically designed

so that the smallest differences between high pressure and suction pressure ensure sufficient oil supply to the bearings,

both at full and partial load.

The built-in oil separator has 3 stages of separation with a 10 mm stainless steel mesh filter ensuring the constant

presence of oil inside, with an oil carry over rate lower than 0.5%. Compressor’s continuous modulation thanks to a slide

valve which, depending on the position assumed, permits the compression’s chamber stepless reduction.

In addition to standard no-load switch-on procedure, the motor

is fitted with electric devices limiting the absorbed current during

start-up. Each compressor is fitted with manual reset motor

thermal protection, controls for the delivery gas temperature and

the oil level flow and an electric resistance to heat the carter while

the compressor is stopped.

Water-refrigerant heat exchangerDirect expansion shell and tube exchanger with asymmetric refrigerant circuits for keeping the refrigerant at the correct

speed inside the tubes during the change from the liquid to the gaseous phase. The steel shell is insulated with a closed-

cell condensation proof lining in foamed elastomer. The copper pipes are internally grooved to improve heat exchange

and are mechanically expanded onto the tube plate ends.

Refrigerant-water heat exchangerFinned coil exchanger with steel shell and finned coil made from copper tubes with external fins, mechanically expanded

onto the tube plate ends. The heads can be removed to inspect the tubes. Water connections are fitted standard for water

from towers; connectors for water from wells can be supplied on request.

Refrigerant circuitMain components of the refrigerant circuit:

- compressor discharge check valve,

- compressor discharge shut-off valve,

- liquid line shut-off valve,

- liquid line solenoid valve,

- dryer filter with replaceable cartridge,

- refrigerant line sight glass with humdity indicator,

- externally equalised thermostatic valve,

- high pressure safety valve,

- low pressure safety valve,

- high and low pressure transducers

- high pressure switches,

- differential pressure switch for water

Group Control DeviceA group composed of various hydronic units permits better management for the lowest running cost.

Coordinating the units for optimized operating times assumes fundamental importance and provides significant

advantages in terms of reliability (e.g. the compressors) while also permitting energy savings and delivering water flows

constantly at the right temperature without fluctuation.

Resources are always used according to the user's requirements without needless compressor cycles or power

absorption peaks. The unit pumps are intelligently managed.

The number of hours of operation is balanced for more efficient maintenance.

Resource priority assignment gives precedence to the unit with greater efficiency: such as chillers with free-cooling

function. The stand-by mode grants response to possible peaks in load.

The elevated characteristics offered by the serial interface keypad are the highest currently available in the market.

Latest Control SystemThe controller W3000 large offers the latest control and functions

specially developed for these units.

The keypad is generously sized with full operating status display.

The controls and detailed LCD make access to machine settings

easy and safe. These resources permit to directly act on the unit

settings through a multilevel menu, available in several languages.

The diagnostics includes full management of alarms with black-box

functions and alarm record for better analysis of unit performance.

For multi-units plants a special device to coordinate and manage all the resources is available as an option; energy

metering device is even possible as an option. Supervision

is easy through Climaveneta devices or with various options for interfacing to ModBus, Bacnet, Echelon LonTalk

protocols. Compatibility with remote keyboard (management up to 10 units). Clock available with programming of

operation (standard 4 days and 10 time bands).

Temperature regulation features the continuous capacity modulation, based on a neutral zone and the return water

temperature control. It´s even possible the steps regulation, based on the return water temperature, with proportional or

proportional+integral logic.

Standard unitStandard unit for production of chilled water

Chiller with Desuperheater, -DUnit for production of chilled water, complete of an auxiliary heat exchanger on the discharge section of the compressor

to the superheat reclaim. The reclaim heat is approximately the 20% of the total cooling capacity. This function is used for

application with domestic hot water production or other secondary uses, as support of the existing boiler.

Chiller with total heat recovery, -RUnit for the production of chilled water, with a dedicated heat exchanger refrigerant/water for the condensation heat reclaim.

The heat reclaim is managed to reach the set-point. This function is used for air treatment in applications with AHU or for

domestic hot water production together with an existed boiler.

Ice Storage System ApplicationsUsed the anti-freeze solutions such as Ethylene Glycol, propylene glycol Mixture as the chilled water, and scheduled the control system, the Climaveneta series of CSRH.C-Y chiller is uniquely suited to low temperature applications like ice storage and industry cooling process.

Data referred to 1.Normal daytime cooling mode: chilled water (in/out)12/7℃, condenser water (in/out) 30/35℃ 2.Ice storage mode: a. chilled water (out) -5.3℃, condenser water (in) 27℃ ( with 25% Glycol solution) b. chilled water (out) -8℃, condenser water (in) 27℃ (with 30% Glycol solution.) 3.Water flow at the units with “*” is controlled to limit the water pressure drop.
