GENERAL FEATURES

Presentation of the unit

This series of air-water chillers and heat pumps satises the cooling and heating requirements of residential plants of medium size.
All the units are suitable for outdoor installation and can be applied to fan coil plants, radiant oor plants and high efciency radiators
plants.
The refrigerant circuit, contained in a compartment protected from the air ow to simplify the maintenance operations, is equipped
with scroll compressors mounted on damper supports, brazed plate heat exchanger, thermostatic expansion valve (standard for IR)
or electronic expansion valve (standard for IP / option for IR), reverse cycle valve, dehydrator lter, axial fans with safety protection
grilles, nned coil made of copper pipes and aluminium louvered ns with subcooling section. The circuit is protected by a safety gas
valve, high and low pressure switches and differential pressure switch on the plate heat exchanger. The plate heat exchanger and all
the hydraulic pipes are thermally insulated in order to avoid condensate generation and to reduce thermal losses.
All the units can be equipped with variable speed fans control that allows the units to operate with low outdoor temperatures in cooling
and high outdoor temperature in heating and permits to reduce noise emissions in such operating conditions.
The low noise acoustic setting up (AS) is obtained, starting from the base setting up (AB), reducing the rotational speed of the fans
and mounting sound jackets on the compressors and the technical compartment is clad with soundproong material of suitable thick­ness.
The eXtra low noise acoustic setting up (AX) is obtained, starting from the low noise setting up (AS), further reducing the rotational
speed of the fans and using nned coil with bigger surface.
All the units are supplied with a management and control electrical panel containing general switch, phase presence and correct
sequence controller, microprocessor controller with display and all the other electrical components with IP54 minimum protection
degree.
All the units are accurately built and individually tested in the factory. Only electric and hydraulic connections are required for instal­lation.

Unit model

The available special versions are described below:

VB: Standard unit.
VD: Version with Desuperheater (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 25 to 30% of the heating
capacity that would otherwise be dispersed in the air. It helps to remind that hot water production is possible only in combination with
cold-hot water production in the main heat exchanger and it is subordinated by it.

VR: Total Heat Recovery version

Produces cold water as in the standard version plus hot water at a temperature of 30 to 55°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. It helps to remind that hot water production is possible only in
combination with cold water production in the main heat exchanger and it is subordinated by it.

Description of the component

1. Fans. Axial type, they are contained in a sheet nozzle and are equipped with a safety grille, scythe-shaped blades increase the

efficiency and reduce the noise level. The fans are directly coupled to the single-phase motor by means of an external rotor. Thermal
protection against operating faults is installed inside the winding. The fans rotational speed can be modulated continuosly by an
analogue device or an inverter (option) to control the condensation pressure (in cooling) and the evaporation pressure (in heating)
in order to extend the operating limits of the unit and to reduce noise emissions. Optionally are available Electronically Commutated
(EC) fans, which ensure maximum energy efficiency at reduced speed of rotation.

2. Electric control and monitoring panel. It contains all the power, control and security components necessary to guarantee the
unit to work properly. The unit is managed by a microprocessor controller to which all the electrical loads and the control devices are
connected. The user interface, placed on the frontal panel, allows to view and to modify, if necessary, all the parameters of the unit.
This is housed in a metal casing in which the various electrical components are positioned on one metal plate.
2a. The power section includes:

• Main door-locking circuit-breaker.

• Fuse-holder that can be isolated with protection fuse triad for each compressor, or thermal magnetic circuit breakers (option).

• Fuse-holder that can be isolated with protection fuse for compressor oil heaters and antifreeze (if installed), or thermal magnetic
