WORKING LOGIC
MULTIPLO SCREW is suitable for independent or simultaneous production of chilled water and
hot water for 4-pipe plants. The unit is equipped with two screw compressors operating on two
independent refrigerant circuits that allow, therefore, to satisfy differentiated thermal and cooling
loads.
On request, the two circuits, can be equipped with plate type heat exchangers (desuperheaters)
for domestic hot water production. Please note that the thermal power produced for the
domestic water ,corresponds to 15÷30% of the chiller thermal power, according to the domestic
water temperature. The production of domestic hot water is subject to the operation of the
machine in cooling only, heating only or contemporary (cooling + heating).
The unit cooling and heating functions are enabled by selectors placed on the electric board,
while the domestic hot water production is always active.
According to the request, MULTIPLO SCREW can produce chilled water and(or hot water in
different percentage, as indicated in the working diagrams.
MULTIPLO SCREW can produce chilled water or hot water with variable loads up to 25% of the
nominal.
With request of simultaneous production of hot water and chilled water, the two compressors
can partialize their operation so as to obtain different working conditions as per following table:

ELECTRIC DATA
MAXIMUM ELECTRIC ABSORPTION CALCULATION
This chapter is showing the maximum electrical absorption calculation of unit (A), corresponding
to extreme working conditions.
The involved components are the following:
Compressors electric motor
Condensers fans electric motors
Water pumps electric motors (if present)
The electrical data of the various components are indicated in the relative technical data sheets.
EXAMPLE n.1:
Calculation for MULTIPLO SCREW 530 V2 U08:
MAXIMUM ELECTRIC ABSORPTION
● Compressors

IMPORTANT
For water pumps and condenser fans, the current nominal values have been considered
equal to the plate value. Therefore the nominal current and the plate current are the
same.
In fact, the real absorbed current is normally lower than the plate value.
These values depend on the unit working conditions and on the control type of the plant.

IDEA®: DYNAMIC CONTROL SYSTEM OF DEFROSTING CYCLES
®
RC GROUP PATENTED the dynamic control system of defrosting cycles which is called IDEA
(Intelligent Defrosting system for Energy-saving Applications).
®
Unlike the traditional defrosting systems (fixed time or pressostatic at static reading), IDEA is
able to identify the actual ice presence on the evaporating coil in order to start the defrosting
cycle only when it is necessary.
This allows an yearly energy saving ranging from 15% to 20%.
Moreover, the system is totally automatic, it does not demand the introduction of any limit control
parameter and it conforms to all climatic conditions.
The advantages of the dynamic system can be easily summarised.
First of all, the heat pump starts defrosting cycles only when they are really necessary.
In this way undesired defrosting cycles are avoided and the temporal sequence is optimized,
reducing or increasing it according to the thermo-hygrometric conditions of the outdoor air.
Another system’s advantage is that it does not demand human intervention.
The other systems demand the definition of limit values: as everyone knows, not always those
who handle a chillers have the necessary skill to do it, therefore they can often make serious
planning mistakes or they can tamper with the system while it is working.
Moreover, during plant working, the conditions of the evaporating coil can change because of
®
the dirt which has formed: IDEA dynamic system is able to conform to the changing conditions.
®
The IDEA system does not demand any human intervention because it is only based on the
dynamic reading of working parameters, which are absolutely objective data that are not subject
to mistakes.
In short, the advantages are the following:
the optimized heat pump working
the optimized plant working
the yearly working saving which ranges between 15% and 20%.
the total absence of planning mistakes
the reduced compressor wear, therefore an higher duration of the heat pump

Set of the working parameters.
Technical compartment and panels insulated with sound-absorbing material.
The LNO KIT allow 3 different type of set:
LNO KIT 100%
No air flow reduction.
Noise reduction is obtained through a different working set of the microprocessor control and an
acoustic insulation of the noise source.
LNO KIT 85%
Noise reduction is obtained through a different working set of the microprocessor control, an
acoustic insulation of the noise source and a reduction of the condenser air flow at 85% of the
nominal value.
LNO KIT 70%
Noise reduction is obtained through a different working set of the microprocessor control, an
acoustic insulation of the noise source and a reduction of the condenser air flow at 70% of the
nominal value.
Consider that a condenser air flow reduction induce a minor cooling capacity of the
machine and a major energy consumption of the compressor.
WARNING
To obtain the effective working conditions of cooling capacity and noise reduction for
machines equipped with LNO KIT, please refer to the electronic selection catalogue RC

before the main condenser.
The system is not regulated and the control is ON-OFF type. The heat recovery system’s
operation is subject to the supply demand of cooling capacity.
The system includes:
Copper brazed plate type heat exchanger with cover plates, plates and connections in
AISI 316 stainless steel.
Anticondensate insulation made of polyurethane.
Antifreeze heater
Hydraulic piping.
The heating capacity which is supplied depends on the kind of refrigerant gas which is used and
working temperatures.
The heat exchangers can produce hot water up to the maximum temperature of 70÷75°C and
according to the working conditions of the unit.
