Introduction
The new generation of SYSCW-AR R513A 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 on the
market units with the highest performance in terms of COP.
Operating range
To enable a much wider operating range and installation using
a water source in an application with a dry cooler, the standard
SYSCW-AR R513A units are designed to operate in a water source
temperature range between 15 and 45 °C.
Cabinet
The cabinet is made of galvanised sheet steel painted RAL 9010.
To facilitate access to the main components, front removable
panel provides access to the compressor, the fan and the electrical
box.
The condensate drain pan has anti-corrosion treatment consisting
of oven‑baked epoxy paint.
The inside of the cabinet, on the fan compartment side, is coated
with 15 mm thick closed cell polyurethane foam thermal‑acoustic
insulation, classied M1.
On the compressor compartment side, the thermal-acoustic
insulation is of 20 mm thick Isofeutre type with heavy mass.
Versions
The SYSCW-AR R513A range is available in several versions :
Q SYSCW-AR VC : standard version with cabinet,
Q SYSCW-AR VCL : low height version with cabinet,
Q SYSCW-AR VN : standard version without cabinet,
Q SYSCW-AR VNL : low height version without cabinet.
Each version can be supplied, as standard, with xed feet (BA
conguration) or with adjustable feet (FA conguration).
Filtration
All units are equipped as standard with a disposable G2 lter.
Access to the lter can be realized by the front or the bottom
(according to the selected conguration BA or FA).
Water connections
The water source outlet and return connectors are located on the
outside of the unit in several congurable positions. They are of
female gas threaded type (1/2").
The condensate drain connection is of smooth tube type with an
outside diameter of 16 mm.
Water feeding sides : BACK / RIGHT / LEFT / BELOW.
A ow switch of SIKA type will be factory supplied as standard in
order to avoid any damage.
Electrical box
Holes are provided in the casing for entry of electrical power supply
and remote control cables.
The electrical power supply for SYSCW‑AR R513A units is
230V/1Ph/50Hz. Compressor is standard 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, and a nned coil. The refrigerant circuit also comprises
an HP pressure switch with automatic reset function and an LP
pressure switch with an automatic reset function. Two direct
external access Schrader valves (HP & LP) are available for pressure
tapping on the refrigerant circuit.
The water/refrigerant heat exchanger is of the brazed stainless
steel plate type, for 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 monitored by the electronic board.
Maximum service pressure water side (10 bar) and refrigerant
side (18 bar). The heat exchangers are particularly well adapted to
the operation of reversible heat pumps with high thermal transfer
rates for a low water ow rate.
The air/refrigerant coil is made 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 R513A refrigerant to be
optimised, in order to maintain a high COP value.
Ventilation section
The fan compartment contains the fan‑motor assembly, the air/
refrigerant coil and the condensate drain pan. The ventilation
section is completely isolated from compressor compartment by a
thermally and acoustically insulated partition wall.
Wide removable panels provide access to the various internal
components. The condensate drain pan has an anti-corrosion
treatment.
Q The standard AC motor of asynchrone direct drive type having
3 speed direct-drive fan motor with ipsothermal protection
against overheating during operation.
Q The EC1 motor of high efciency and low electrical
consumption type for a signicant energy saving. The motor
is suitable for 0-10 V input, ensuring variable speed capability.
The 3 fan speeds can be controlled either manually or
automatically by the electronic management board of the unit
