PRESENTATION
Multipurpose OUTDOOR units for 2 or 4 pipe
systems, especially designed for simultaneous
production of cold and hot water and fully
independent.
AVAILABLE VERSIONS
3.1.
FOR 2 PIPE SYSTEMS
The multipurpose 2-pipe units have been made
for applications with 2 pipe terminals, e.g. hotels,
where there is a cold/hot water and DHW demand
throughout the year.
The operating modes are:
SUMMER FUNCTIONING
1.
Cold water production to system.
2.
Production of domestic hot water with use of
total recovery (NO ANTI-LEGIONELLA CYCLE).
WINTER FUNCTIONING
3.
Heat pump supplying the system.
4.
Service heat pump of DHW.
4.
3.2.
This separates the two hot-cold sections required for
4-pipe systems.
FOR 4 PIPE SYSTEMS
The multipurpose 4-pipe units have been made for
applications with 4 pipe terminals, e.g. shopping
centres, offices or facilities with large windows
where there can be the simultaneous demand for
hot and cold water with a system which does not
require season changeover and therefore is a valid
alternative to traditional systems based on the
chiller-boiler combination.
The microprocessor control logic ensures perfectly
satisfying heat and cooling loads.
The operating modes are:
PRODUCTION OF COOLED WATER ONLY
The multipurpose unit acts as a classical refrigerator:
cool water to the system and condensation heat
disposal outside through finned coils.
PRODUCTION OF HOT WATER ONLY
The multipurpose unit acts as a heat pump,
exploiting the heat of the outside air, through the
finned coil (evaporator) it raises the temperature of
the water to be sent to the system through a plate
heat exchanger (condenser). The main difference
from traditional cycle reverse heat pumps is that
the heated water is produced in different heat
exchanger from the one used to produce cold water.
COMBINED PRODUCTION
If the utility requires simultaneous hot and
cold water, the unit acts as a water heat pump,
controlling condensation and evaporation on
two distinct plate heat exchangers associated to
circulation of cold and hot water in the system.
It automatically changes from one configuration to
another (managed by on-board microprocessor)
to optimise the spent energy depending on the
demand by the utility.
Maximum reliability
Multi-circuit unit designed to provide the maximum
efficiency both with full load and partial loads,
guaranteeing operating continuity should one of the
circuits stop to facilitate maintenance.
Having several compressors and circuits ensures
control of more steps of power yielded in both
modes.
Built-in hydronic kit
Encloses the main hydraulic components; available
in several configurations with high or low static
pressure single pump or reserve pump (see
configurator).

HEATING SIDE SYSTEM 4 pipes)
Braze welded AISI 316 steel plate heat exchanger,
insulated externally with closed cell neoprene anticondensation material. When the unit is not running,
it is protected against formation of ice inside by an
electric resistance.
AIR SIDE COIL EXCHANGER
Finned pack heat exchanger made with copper pipes
and aluminium fins adequately spaced to ensure
better heat exchange performance.
CYCLE REVERSING VALVE (2 PIPE)
4-way cycle reversing valve. Inverts the flow of
refrigerant gas.
RECOVERY ENABLE VALVE
4-way valve enables the recovery heat exchanger.
LIQUID STORAGE TANK
(always passed by)
Compensates the difference in volume between
finned coil and plate exchanger, retaining excess
liquid.
LIQUID SEPARATOR
Located on the suction point of the compressor, to
protect against any flowback of liquid refrigerant,
flooded start-ups, operation in the presence of
liquid.
12
DEHYDRATOR FILTER
Hermetic-mechanical with cartridges made of
ceramic and hygroscopic material, able to withhold
impurities and any traces of humidity present in the
cooling circuit.
ONE WAY VALVES
Allows one-way flow of the refrigerant.
THERMOSTATIC VALVES
Two valves installed:
(cooling mode and recovery mode)
Mechanical valves, with external equaliser
positioned at evaporator outlet, modulates the flow
of gas to the evaporator, depending on the heat
load, in order to ensure a correct heating level of
the intake gas.
circuit, it signals the work pressure to the control
board generating a pre-warning in the case of
anomalous pressures.
HIGH PRESSURE TRANSDUCER
Placed on the high pressure side of the cooling
circuit, it signals the work pressure to the control
board generating a pre-warning in the case of
anomalous pressures.
RELIEF VALVES
They intervene by discharging the overpressure in
the case of anomalous pressures.
- Calibrated at 45 bar on HP branch.
- Calibrated at 30 bar on LP branch.
INDICATOR FOR LIQUID
Used to check presence of humidity in cooling
circuit.
CONDENSATION PRESSURE CONTROLLER
This device allows correct functioning with external
temperatures lower than 10°C and as low as – 10°C.
It consists of an adjustment circuit board that
varies the number of fan revs according to the
condensation pressure read by the high pressure
transducer, in order to keep it sufficiently high for
correct unit functioning.
It also allows correct functioning in heating mode
with external temperatures exceeding 30°C and up
to 42°C.
7.4.
7.6.
SOLENOID VALVES
The valve closes when the compressor switches
off, blocking the flow of refrigerant gas to the
evaporator, recovery and the coil.
STANDARD HYDRAULIC CIRCUIT
WATER FILTERS
Equipped with steel filtering mesh, prevents the
heat exchangers both of the system side and the
DHW/heating system side from clogging.
FLOW SWITCHES
They have the task of controlling that there is water
circulation inside the heat exchangers; if this is not
the case, they block the unit.
AIR VENT VALVE
Mounted on the top of the hydraulic system; they
discharge possible air pockets.
7.4.1.
COMPONENTS OF HYDRAULIC CIRCUIT
IN CONFIGURABLE VERSIONS
PUMPS

OPERATIONAL LIMITS
10.1. COOLING MODE
COOLING MODE
The units, in standard configuration, are not suitable
for installation in salty environments.
For functioning limits, please refer to the diagrams,
valid for ∆t 5°C/10°F.
EXTERNAL AIR TEMPERATURE (d.b.)
In summer mode, the unit can be started with
external air 46°C/114,8°F and inlet water 35°C/95°F.
In winter and RECOVERY mode, the unit can be
started with external air -15°C/5°F and inlet water
20°C/68°F.
In these conditions, operation is only allowed for a
short amount of time and to bring the system to the
proper temperature.
To shorten this operation, it is recommended to
install a three-way valve which makes it possible to
bypass the water from the utilities to the plant, until
achieving conditions which allow the unit to work
within the allowed operating limits.

EXPANSION VESSEL CALIBRATION
14.1. EXPANSION VESSEL CALIBRATION
Ptar = H / 10.2 + 0.3
H max (1) = 55 m
Standard pre-load pressure value of the
expansion vessel is 1,5bar/21,8PSI, whereas
volume is 24 litres. Maximum pressure
6bar/87PSI.
Calibration of the vessel must be regulated using
the maximum level difference (H) of the user (see
diagram) by using the following formula:
p (calibration) [bar] = H [m] / 10.2 + 0.3.
For example: if level difference (H) is equal to
20m/65,6ft, the calibration value of the vessel will
be 2,3bar/33,4PSI.
If calibration value obtained from formula is less
than 1,5bar/21,8PSI (that is for H < 12.25), keep
calibration as standard.
H = 12.25 m
Ptar = 1.5 bar
H
Ptar = 1.5 bar
H=0m

KEY
(1) Check that highest installation is not higher than 55 metres.
(2) Ensure that lowest installation can withstand global pressure
in that position.

1. The hourly number of inversions
between functioning modes.
2. Decrease in water temperature during
winter defrost cycles.
