ENERGY SAVING
The reduction in investments and operation costs, together with the current regulations regarding the cost saving and environmental compatibility, are the factors that become always more essential in the choice of technologically advanced units,
which are characterized by high performance thanks to the electronic regulation of the components. Their use in continuous
working applications has confirmed high reduction in operating costs, making possible remarkable strategies of energy
saving and plant technological integration in all fields, particularly in the industrial one.
COMPACT DESIGN, INDOOR INSTALLATION
The units of RWH / PWH Ka series are used for production of chilled water for technological plants or for production of
hot water for both DHW (domestic hot water) and heating; they are units for indoor installation, composed of one or two
R134a cooling circuits and two hydraulic circuits (cold side and hot side). The definitely compact structure of this range
is an essential element for indoor installation in limited spaces. The use of screw compressors allows the unit to have
partial loads of cooling capacity according to the requirements of the plant, running in optimal conditions of efficiency.
LOW SOUND EMISSION
It is possible to obtain reduction of sound emission by making a sound-proof cabinet over the compressors made of aluminum
profiles and openable panels in aluminum alloy. The cabinet insulation can be made of standard sound-proof materials or of
oversized thickness material in relation to the required acoustic reduction level. In this way it is possible to install them even in
residential areas where current regulations impose to follow binding standards of noise
FLEXIBLE CONFIGURATIONS, VARIETY OF APPLICATIONS AND SPECIAL EXECUTIONS
Multiple configurations together with a wide capacity range ensured by a variety of sizes, make this series suitable for various
applications. Moreover, it is possible to ensure correct adaptability to the plant’s requirements thanks to partial loads of cooling
capacity, provided by sophisticated regulation logics and control accuracy that allow to improve the cooling cycle and to operate
at high values of efficiency. The available accessories allow to personalize the unit in relation to its own needs.
OPERATING LOGIC
Electronic regulation with microprocessor controls and manages all present actuators (in terms of schedule, rotation and
safety). Moreover, in the unit there is an electronic regulation PID of overheating by means of electronic expansion valve,
optimizing the running of the unit and allowing cost saving. The microprocessor controls the water temperature, carries out self
diagnostics of anomalies, remote management and supervision of the unit. An internal memory records the running conditions
when an alarm arises, so to show it then on the unit on-board display.

3. Construction features
The air cooled liquid chillers and heat pumps of RWH and PWH series, with
cycle inversion on user side, are extremely compact units designed to reduce
installation spaces and weight. They are designed for indoor installation and are
particularly suitable for air conditioning application in cooling/heating plants,
especially in commercial, services and industrial sectors, where it is necessary to
have a certain level of thermo-cooling capacity and to ensure excellent seasonal
performance and low environmental impact. Depending on the cooling capacity,
one or multi compressors versions with 1 and 2 independent cooling circuits with
R134a refrigerant and double hydraulic circuit are available. The use of screw
compressors allows the chillers and heat pumps to have various partial loads of
cooling and thermal capacity. Electronic regulation with microprocessor controls
and manages all the components and parameters of unit running; an internal memory records running conditions when an alarm arises, so to show it then on the
unit on-board display. Thanks to the various available options , these chillers and
heat pumps are particularly versatile and easily adoptable to various plant types.
Thanks to the applied design technology, the chillers and heat pumps are able
to control with high precision the leaving fluid temperature from the shell & tube
exchanger (user’s side), modulating the cooling or heating capacity according to
the plant’s requirement, all automatically managed by the on-board microprocessor. High technology used in design stage, as well as the use of the best components present on market, make the units very reliable and thus able to work for
long periods without stops. These units (completely assembled and factory tested,
supplied with refrigerant R134a and non-freezing oil charge) are particularly easy
for installation, as well as for ordinary and extraordinary maintenance.
1. Available configurations
The units are available in chiller or heat pump versions:
RWH / PWH ST Ka: STANDARD VERSION
4. Frame
The frame is a compact and strong structure made of steel press bended profiles,
painted with color RAL 9005 (black) and integrates the exchangers of evaporator
and shell & tube condensers on which all the components are mounted at sight.
On request, the compressors can be acoustically insulated with a cabinet made of
standard sound-proof material (option CF) or made of reinforced material with double thickness layer (option CFU) to reduce the sound level of the unit furthermore.

5. Compressors
Compressors are of semi-hermetic screw type, equipped with capacity steps, motor thermal protection, oil crankcase heater, shut-off valve on discharge and phase
monitor. Compressors lubrication is of forced type without pump and in order to prevent an excessive oil migration to the cooling circuit, the compressors are equipped
with an oil separator, in-built on the discharge side. The reduction of inrush current
can be made through Part Winding system (standard with the sizes equipped with
compressors which provide it R/PWH 281 / 321 / 361 / 452 / 562 / 642 / 732 Ka ) or
through star-delta connection(option DS).

6. Shell & tube Heat Exchangers
8. Electric board on the unit
Evaporator is of dry expansion, single-step type (fluids flow in perfect countercurrent) with pipe bundle expanded in steel flange head. The copper pipes are with
a special internal corrugation (freon side), the shell and tube plate are in carbon
steel. The evaporator has got a condensate-proof insulation made of close-cell
polyurethane foam material and external UV ray-resistant and scratch-proof cover (thickness 10 mm). Inside the shell some corrosion-proof baffles are suitably
placed allowing correct water distribution and making the tube bundle particularly
strong and vibration-free, even in case of very high water flow. The condenser
is of single-step type, with water flow on pipe side (finned externally and rifled
internally) and freon on shell side. The possible insulation is supplied in the heat
pump version (option CC). The design pressure of both tube bundles is 10 bar
(water side).
Electric board is built in compliance with the norms in force. Inside of the board all
the components of the control system and the components necessary for the motors starts are installed, all factory tested and connected. Its structure is suitable
for internal installation and contains power and control devices, microprocessor
electronic board provided with keyboard and display to show available functions,
main switch, isolation transformers to feed auxiliary circuits, automatic switches,
fuses and contactors for compressors and fans motors. The unit management
electronic microprocessor is installed inside the electric board and equipped with
compressor hour counter, with the function of alarm recording in alarm log and
hour rotation programmingamong units. For this reason it would be preferable
to define in phase of order the necessary information to be implemented in the
dedicated program.
9. Partial condensing heat recovery
(Option RP)
Partial heat recovery of condensation heat is made by means of refrigerant/water
exchanger (desuperheater) installed in series on the cooling circuit. It is only
used for buffer tank loading with the purpose of domestic hot water production.
On each cooling circuit, one dedicated desuperheater (appropriately insulated)
is installed.
7. Electronic expansion valve
Electronic expansion valve is installed in series on all the units. Lamination capacity of the expansion valve is determined by the difference of existing pressure immediately upstream and downstream. By electronic regulation, there is
an accurate and reliable regulation, that ensures an increase of cooling cycle
efficiency. The control of the opening rate of the valve is made according to the
various working conditions and is controlled by a specific driver.
10. Total condensing heat recovery
(Option RT)
Total recovery of condensing heat is carried out by means of double shell &
tube condenser, managed in parallel to the condensing section. It is used for
applications where it is necessary to heat industrial water or for sanitary water
heating. The exchanger is thermally insulated with 10 mm thickness cover
protected by scratch-proof layer.

11. Liquid injection
(special execution)
12. Economizer
(special execution)
In case the unit is foreseen to operate in particularly hot climatic zones or with
very high compression ratio when the heat pump is required to work at very high
temperatures of condensation, it is possible to provide a liquid injection. In particular, having reached the limit temperature, the solenoid valve opens allowing an
outflow of a part of condensed fluid with its direct injection inside the compression
volume of the compressor, which will be cooled in this way. The outflow will be
stopped when the discharge temperature returns to the acceptable values.
The economizer, with the external circuit to the compressor, must carry out the
subcooling of liquid leaving the condenser in order to increase efficiency of the
cycle. In particular, with this subcooling, it becomes available the mass flow that
is sent to the evaporator with a vapor quantity (lamination end), inferior than
what would happen in a normal cooling circuit with simple compression. As a
result, there is an increase of cooling capacity against a little increase of absorbed power from compressor as it must work out the additional mass flow
of economizer circuit. Therefore it is obtained the above mentioned increase of the coefficient of refrigeration cycle efficiency profit, especially for high
compression ratios or in heat pumps operstionat low outdoor temperatures.
It is made up of by plate heat exchanger and thermostatic expansion valve.

12. REGULATION OF CONDENSATION THROUGH PRESSOSTATIC VALVE (OPTION VP)
Regulation of condensation is carried out through valve installed on hydronic side in outlet from the condenser and is required for regulation of hydraulic flow rate to
the exchanger on source side (condenser) according to the condensing pressure (through the sensor in the valve body). With the aim to ensure the correct pressure
delta on thermostatic device and a sufficient compression ratio to the compressor, in case the exchangers on source side are fed with a fluid at low temperature, it
is used a modulating regulation of the primary fluid flow with reference to the minimum condensation pressure, admitted by cooling group. The modulation of fluid
flow, feeding the condenser, is made through a pressostatic valve that increases the flow rate on the increasing of condensation pressure. Being the condensation
pressure also related to the unit cooling capacity, the fluid flow rate is varied by the valve in order to keep the condensing pressure/temperature on the working set
point of the unit. The valves, reported in the table, have been selected with the nominal flow rate of the condensers referring to 5°C delta. This control is suggested in
applications with well water or spring water, similar to low temperature, where condensation control is required and it is possible to work with variable flow rate in the
heat dissipation circuit. The valve is installed on the condenser outlet in order to keep it always wet and avoid corrosive phenomenon.

DESCRIPTION ACCORDING TECHNICAL SPECIFICATIONS
SUBJECT: WATER COOLED CHILLERS AND HEAT PUMPS WITH WATER SIDE INVERSION
CYCLE AND SCREW COMPRESSORS.
The frame is made of steel press bended profiles, painted with color RAL 9005 (black)
that integrates the exchangers of evaporator/condenser unit and on which all the components are mounted.
Compressors are of screw semi-hermetic type, equipped with oil separator integrated on
the discharge side with three stages of separation, VI self-adaptive ratio, capacity steps
system (standard 100% - 75% - 50% - 25%) or modulating system (stepless 100% - 25%)
on request, motor thermal protection, crankcase heater, phase monitor and shut-off valve
on discharge. The compressors lubrication is of forced type and circulation is detected by
flow switch which checks obstruction of integrated filter as well. Moreover, there are two
side sight glasses placed correspondingly at MIN and MAX oil level inside the compressor casing. The standard electric motor is powered 400V/3PH/50HZ and is pre-arranged for starting at reduced inrush current through the Part Winding system (standard on
compressors providing it) or Delta-Star connection on request (option DS) during which
the compressor is 25% load forced after having completed the back discharge pressure
unloading. In order to avoid the problems related to accidental short circuits, it is foreseen
a mechanical interlock of remote control switches of electric motor. The power cables are
connected inside of in-built electrical box having IP65 protection degree.
The compressor is equipped with discharge in-built check valve, overpressure safety
valve and PTC probe to control the temperature limits of discharge. The wide operating
range of compressor allows to work at high condensing temperatures.For ordinary evaporation temperatures, referred to chilled water production over +5°C, forced oil cooling
or liquid injection is not necessary.
Condenser is of shell & tube single-step type, with one cooling circuit and one water
circuit made of pipes in special high performance copper, finned externally and rifled
internally, to improve the exchange factor keeping low the value of fouling factor. The
exchanger can be insulated on request by a polyurethane foam material (thickness
10 mm) with an external scratch-proof cover (option CC for PWH Ka only). The design
pressure is 10 bar (water side).
Evaporator is of shell & tube, single-step, dry expansion type with tubes in pure electrolytic
copper having internal helical scoring optimized for increasing the exchanging surface
(refrigerant side). The plating is provided with series of intermediate sections in plastics
with high thickness which grant a correct water distribution and make the shell particularly resistant and free of vibrations even in case of high flow rates. The design pressure
of exchanger is 10 bar for water side. Shell, heads and tube plate are made of special
carbon steel resistant to low temperatures. The head seals are asbestos-free and suitable for use with HFC refrigerants. Inlet and outlet water connections are of flexible connection type and equipped with thermometric pockets for inserting temperature probes.
The shell is complete with 1/2“ gas connection for water discharge in order to completely
empty the exchanger in case of maintenance or stops of the plant.
The exchanger has a condensate-proof insulation made of close-cell polyurethane foam
material and external scratch-proof cover.
Cooling circuit is composed of pure cooper (or steel) pipes of appropriate thickness,
electronic thermostatic valve, type-approved liquid receiver (option LR for RWH Ka),
dehydrating filter with interchangeable cartridges, liquid sight glass and humidity detecting device, safety devices for high and low pressure, high and low pressure gauges, shut-off valve on liquid line, check valve on discharge and refrigerant charge valve.
Electric board is contained in an appropriate cabinet, protected by a security panel and
equipped with lock-door main switch. Inside of the board, control and protection components, terminal box and auxiliaries are installed. Moreover the board contains a supply
phases control device to prevent the compressor’s rotation in opposite sense different
from the foreseen one. Inside the board there is a microprocessor complete with display.
The dedicated microprocessor is made up of: IN/OUT electronic card, LCD display, key
board and LED signals. This system allows P or PI regulation of the evaporator inlet or
outlet water temperature, setting of the operation parameters, alarms management, reading of the measured values (temperatures, working hours, etc.) and possibility to control
them through a supervision system. It is also possible reading and setting all the operating parameters of the system and displaying all the existing alarms with diagnostics and
possible reset. The user’s terminal can be positioned up to 30 m away, simply removing
it from the unit board and using a 6-pole telephone cable (up to 100 m using screened
cable). Thus, the programming of the unit is easier and more comfortable. Moreover, the
board is equipped with serial interface RS 485 for monitoring and remote controlling the
unit through GSM/TCP-IP/MODBUS protocols.
The main control algorithms are the following
-C ontemporary regulation of evaporator in/out temperature with specific algorithm P or
PI;
-A nti-freezing control in exchanger outlet;
-Prevent actions for refrigerant high and low pressure alarms;
