Introduction
The new generation of SYSLOOP model reversible water source heat
pumps is the fruit of our considerable product experience and our
awareness of the market, all combined with a technology based on
theenergyefciencyofmachines,inordertoprovideforunits with
the highest performance in terms of COP.
Range
The SYSLOOP horizontal units are designed for installation in
specically designed false ceilings or in technical rooms, and are
available with a range of nominal cooling capacity ratings of between
1.5 and 2.9 kW, with 3 modelsusingasinglecasingsize.
Operating range
To enable a much wider operating range and operation using a water
source in an application with a dry cooler, the standard SYSLOOP units
are designed to operate in a water source temperature range of
between 11 and 45 °C.
Casing design
The casing is made of galvanised sheet steel. To facilitate access to
the main components, wide removable panels provide access to the
compressor, the fan and the electronic control box.
The condensate drain pan has anti-corrosion treatment consisting of
oven-baked epoxy paint.
Compressor section is thermally and acoustically insulated with 15 mm
thickIsofeutre.VentilationsectionisclassiedM1.
Unitsareinconformitywith "ERP Building Receivingthe Public" re
standard.
Filtration
AllunitscanbeequippedwithabasiclterorG3M1disposablelter,
23 mm thick. The lter can be removed/installed from the side of
the units or from the bottom without having to remove the optional
return duct.
Hydraulic connections
The water source outlet and return connectors are located on the
outside of the unit, on the compressor compartment side. They are
malegastypetappedttings,internaldiameter1/2".
Evacuation of condensates is realized with no need of siphon by
positivepressureandgravitationalow.
The condensate evacuation connection is with an external diameter
of 16 mm.
Electrical box
The electrical box is located on the hydraulic service side.
A wide access panel is provided to facilitate the maintenance
operations.
Units are equipped with power on and fault indicating lights located
on the lower side of the unit, allowing quick checking of the power on
presence and status of the units without intervention.
Theelectricalpowersupplyis230V/1Ph/50Hz.
The compressors are factory equipped with an internal thermal
protection with an automatic reset function.
Refrigerant circuit
The refrigerant circuit comprises a rotary type hermetic compressor,
a cycle reversal valve, a water/refrigerant heat exchanger, a liquid
receiver,acapillaryexpansiondeviceandannedcoil.
The refrigerant circuit also comprises an HP pressure switch and an
LP pressure switch both with automatic reset function. Two Schrader
valves (HP & LP) located on the service side are available for pressure
measurement on the refrigerant circuit.
The compressor, mounted on spring anti-vibration mounts, is integrated
in a compartment coated with a reinforced acoustic insulation, which
reduce noises. Its clamping, necessary during transportation, can be
released from the outside of the unit.
The water/refrigerant heat exchanger is of copper / stainless steel
coaxialtypeforanincreasedefciency.
Theanti-freezesafetyoftheheatexchangerisprovidedbyawater
pipe sensor located on the water outlet of the unit.
Optionalwaterowprotectioncontrolledbytheelectronicboardof
the unit is available.
Maximum service pressure is 40bar. The heat exchangers are
particularly well adapted to the operation of reversible heat pumps
whichhavehighthermaltransferratesforalowwaterow-rate.
The air/refrigerant coil is made up of aluminium ns which are
mechanically crimped onto copper tubes. The geometry of the coil and
ofthenprolehavebeencarefullydesignedtoprovidemaximum
efciencyintheoperationoftheunits.
The cycle reversal valve is designed to be normally energised in
heating mode. This logic enables the heat pump to continue to operate
in cooling mode if this valve fails.
The liquid receiver enables the charge of R410A refrigerant to be
optimised, particularly in cooling mode, in order to maintain a high
COP value.
A capillary expansion device ensures and enables a wide operating
range with water inlet temperatures which can vary between 11 °C
and45°Cattheminimumormaximumow-rate.
Ventilation section
The fan compartment contains the fan-motor assembly, the air/
refrigerant coil and the condensate drain pan.
Wide removable panels provide access to the various internal
components. The condensate drain pan has an anti-corrosion
treatment.
All the units are equipped with fan motor with permanent magnet
electronically commuted technology - EC motor -. The fan impeller is
equippedwithaerodynamicallyshapedbladeslimitingairownoise.
The impeller is of metal material. The scroll is of ABS material.
The3fanspeedscanbecontrolledeithermanuallyorautomaticallyby
the electronic management board of the unit.
The standard congurationis in lineairdischarge in theaxisofthe
return air. The L return air option is possible by permuting the side and
the fan-motor assembly panels. The L discharge air option is carried
out with a plenum.
The return air is available with either rectangular ange or with a
circularcollarofØ200mmandafreshaircircularcollarofØ100 or
Ø125 mm.
DischargeairisavailablewitheitherrectangularangeorØ200mm
circular collar.
U version is available by combining L return air with a discharge
plenum.
Anairdiffusionnozzlewithinternaldeectormountedatthefanoutlet
allowstheairowtobeoptimallydistributedontheheatexchangerin
order to ensure maximum heat exchange.
Fixation
Units are equipped with multi-position brackets for easy installation
andholesspeciallydedicatedfor"gripl"hanging.
In order to facilitate installation on site, a suspension kit consisting of
rubber blocks and washers is supplied with the units.
Optional features (factory installed)
 Electricheateratdischargeside(1200,1600,2000W),
 Generalalarmsfaultreport,
 Motorizedwatervalve,
