Unit description

This new series of industrial chillers and heat pumps has been designed to meet the demands of global markets in the smallmedium 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 and heat pumps condensed in air with axial fans suitable for outdoor installation: the structure and panels are robust, made of galvanized and painted steel; all fasteners are made of stainless steel or galv

anized steel, the frame containing the electrical equipment and all the components exposed to weather have a minimum IP54 degree of protection. This series is composed of twelve models divided in four sizes with nominal cooling capacity from 53.5 to 200 kW and thermal capacity from 57.5 to 214 kW. The units product cold water from 5 to 25°C (in summer) and hot water from 30 to 55°C (in winter) and as standard they are equipped with continuous adjustment of axial fans rotating speed in order to allow the units to operate both with low outdoor temperature in cooling mode and with high outdoor temperature in heating mode as well as to reduce noise emissions. All the units are equipped with 2 scroll compressors arranged in pairs (tandem) on 1 circuit operatin

g with environmental friendly R410A gas, brazed plate heat exchanger completely insulated and protected by water side with a differential pressure control and with an antifreeze electrical heater, coil heat exchanger made of louver aluminum fins and copper tubes, axial fans with profiled blades to contain noise and with thermal protection built-in, on-board electrical control panel equipped with control system to manage the main functions. Hydronic group (MP) composed of fittings and connections is available as an accessory with 1 or 2 pumps and also with high available head pumps or with Inverter modulating pump; the accessory Water Storage Tank (SAA) is completely insulated and available on delivery side or for primary-secondary hydraulic circuit (Victaulic connections already in place) depending on the kind of plants to serve. A variety of other accessories are available to extend the capabilities of the units. During the design of the units particular attention has been given to achieve high system efficiency, to reduce overall energy consumptions and 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) which provides sound attenuation thanks to sound absorbing insulation in compressors area, sound jackets on compressors and reduced speed axial fans, or a Extra low noise unit (AX), which provides in addition slower axial fans and more powerful finned coils. 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.

VB - Standard Version VD - Desuperheater unit VR - Total heat recovery unit

The available special versions are described below:

VB: Standard unit. VD: Desuperheater unit (available forboth IR units and IP units)

Produces cold water in the same way as the standard version plus hot water from 30 to 70°C at the same time. This is achieved by installing a water-refrigerant gas heat exchanger between the compressor and coils in order to recover 15 to 20% of the heating capacity that would otherwise be dispersed in the air.

VR: Total Heat Recovery unit

Produces cold water as in the standard version plus hot water at a temperature of 35 to 50°C at the same time. This is achieved thanks to a water-refrigerant gas heat exchanger that totally recovers the heating capacity that would otherwise be dispersed in the air. The total heat recovery function is enabled and disabled by means of a valve on the compressor delivery of each circuit: when the temperature of the water that enters the recuperator drops, the valve switches the hot gas flow from the condensing coils to the recovery heat exchanger. On the other hand, when the temperature of the water reaches the set-point, the valve shuts off the heat recuperator and switches the hot gas flow to the condensing coils.

10. Safety valve. Installed on the delivery pipe of the compressors, this operates if extreme faults should occur in the plant.

11. Fluid cock. Ball type, this allows the gas flow on the fluid line to be turned on and off. Along with the cock on the compres-

sor delivery, it allows the components of the fluid line to be subj

ected to extraordinary maintenance work and the compressors

to be replaced if necessary (without discharging the coolant from the unit).

12. Compressor delivery cock. Ball type, allows the gas delivered to the compressors to be turned on and off.

13. Dehydrator filter. Mechanical type. Retains impurities and traces of moisture in the circuit. Hermetic type for models 50÷80; cartridge type for models 90÷200.

14. Fluid and humidity indicator. Signals when fluid passes through the circuit, indicating that the coolant charge is correct.

The fluid indicator light also indicates the amount of moisture in the coolant by changing colour.

15. Low pressure switch (N°1 of series IR version, N°2 of series IP version). With fixed setting. It is installed on the suction pipe and blocks the compressors if the operating pressures drop below the tolerated values. Automatically resets as the pressure increases. If it activates frequently, the unit will block and can

only be restarted by resetting via the user interface terminal.

16. High pressure switch (n°2). With fixed setting. Are is installed on the delivery pipe and blocks the compressors if the operating pressures exceed the tolerated values. If it activates, the unit will block and can only be restarted by resetting via the user interface terminal.

17. Thermostatic valve. With external equalizer, this supplies the evaporator correctly, keeping the selected overheating degree at a steady level.

18. Water differential pressure switch. This is standard supply and is installed on the connections between the water inlet and outlet of the exchanger. It stops the uni

t if it activates.

19. Pressure taps: 1/4 " SAE (7/16" UNF) type with flow regulator. Allow the operating pressure of the system to be measured: compressor delivery, lamination component inlet, compressor intake.

20. Pressure taps: 5/16 " SAE type with flow regulator. Allow the charge/discharge of the gas from the system, precisely from compressor outlet an expansion valve inlet.

21. Electrical heating elements to heat the compressor oil. "Belt" type. These activate when the compressor turns off and keep the temperature of the oil sufficiently high so as to prevent coolant from migrating during these pauses.

Fluid receiver (IP unit only), this is a plenum tank that accounts for variations to the coolant charge the machine must supply as the summer/winter operating mode varies.

Fluid separator (IP unit only), on the compressor intake to protect against possible fluid back-flows.

MODE key : used to select the operating mode ON/OFF key : used to turn the unit ON/OFF and to reset the alarms Mode + ON/OFF keys : used to access and quit the various menu levels UP key: scrolls forwards through the menu items or increases the value of a parameter Tasto DOWN:

scrolls backwards through the menu items or decreases the value of a para-

meter.

KOP - Programmer clock (F). Allows the unit to be turned on and off depending on the programmed time setting (up to 14 switching actions can be programmed as required throughout the 7 days of the week).

RAG: Antifreeze heating element for the accumulation tank (M/F). Plug type. This activates in parallel with the evaporator’s antifreeze heating element and keeps the water at a temperature able to prevent ice from forming when the unit remains idle during the winter.

TAT- High Temperature Thermostat (M). Two thermostats in series on compressors outlet pipes preserve operation not allowing temperature to rise up than a specified non adjustable value.

SND- External Air Probe (M). External air probe mounted near coil allows smart defrosting, climatic variation of setpoint and enables heat pump stop reducing the external air temperature below a setpoint.

INT - Serial interface (F). Allows serial communication on RS485 by MODBUS protocol

FLS - Flow switch (F). Paddle flow switch on the water circuit to avoid the risk of freezing if the water flow is shut off for some

reason.

SS - Soft Starter (M). Soft starter for compressor, reduce the maximum starting current up to 60% of nominal starting current.

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

and reduce power input.

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

CSF - Voltage monitor and sequence meter (M). The device enables control of the correct sequence of power phases and the

lack of any phases. 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.
