GENERAL FEATURES
Presentation of the unit
This series of air-water chillers and heat pumps satisfies 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 floor plants and high efficiency radiators
plants.
The refrigerant circuit, contained in a compartment protected from the air flow to simplify the maintenance operations, is equipped
with scroll compressors mounted on damper supports, shell and tube heat exchanger with threaded or victaulic fittings (according to
the model), thermostatic expansion valve (standard for IR) or electronic expansion valve (standard for IP / option for IR), reverse cycle
valve, dehydrator filter, axial fans with safety protection grilles, finned coil made of copper pipes and aluminium louvered fins with

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 soundproofing 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 finned 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.

The available special versions are described below:
VB:

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&deg;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 unit
Produces cold water as in the standard version plus hot water at a temperature of 30 to 55&deg;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.

Based on type and percentage of glycol extract CCPT, CCQA, CCDP.
Then calculate.
Pt_brine = kWtr x CCPT
Pass_CP_brine = kWa x CCPA
Then calculate brine flow rate to the heat recovery exchanger:
Q_brine [l/s]=CCQA x (Pt_brine [kW]*0.86/∆T_brine)/3.6
where ΔT_brine is the temperature difference outlet-intlet heat recovery exchanger:
∆T_brine=Twout_brine-Twin_brine
With this brine flow rate enter in abscissa on the water pressure drop of the heat recovery then you have Dp_app.
Finally you can calculate the actual pressure drop of the brine on heat recovery:
Dp_brine =CCDP x Dp_app

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 of the evaporator:
Q_brine_evap [l/s]=CCQA x (Pf_brine [kW]*0.86/ΔT_brine)/3.6
where ΔT_brine is the difference inlet-outlet evaporator water temperature:
ΔT_brine=Twin_evap_brine-Twout_evap_brine
With this brine flow rate enter in abscissa on the water pressure drop of the evaporator then you have Dp_app.
Finally you can calculate the actual pressure drop of the brine on evaporator side:
Dp_evap_brine =CCDP x Dp_app

Based on leaving water temperature of the evaporator and condensing temperature = 7&deg;C extract Cooling Capacity
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_evap [l/s]=CCQA x (Pf_brine [kW]*0.86/DT_brine)/3.6
where DT_brine is the difference between inlet-outlet evaporator water temperature:
DT_brine=Twin_evap_brine-Twout_evap_brine
With this brine flow rate enter in abscissa on the water pressure drop of the evaporator then you have Dp_app.
Finally you can calculate the actual pressure drop of the brine on evaporator side:
Dp_evap_brine =CCDP x Dp_app

NOISE LEVELS
Open field
Q=2
The noise levels refer to units operating in the nominal conditions (A35W7), due to a change of
external air temperature noise levels may change to ensure proper functioning of the unit within
operating range.
The acoustic pressure levels are calculated 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, is certified
according to the Eurovent certification program.
Eurovent certification (E) exclusively refers to the Total Sound Power in db(A), 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 (Eurovent 8/1).
