GENERAL DESCRIPTION
INTRODUCTION
AIRCOOLAIR range is developed from ECOLEAN liquid chiller range and
exists in two versions:
•
AIRCOOLAIR SPLIT UNIT
it can be used for medium to large commercial cooling and heating
applications when the premises are not directly accessible from the roof.
AIRCOOLAIR split unit exist in cooling only and heat pump versions.
•
AIRCOOLAIR CONDENSING UNIT
It is the outdoor unit without the supply section. This unit is available as
cooling only or as heat pump and can be combined with air handling
units. It provides you with a low noise level, high effi ciency and almost
customized units.
Casing
- Casing made of galvanized steel sheet metal painted with a
white RAL 9002 powdered polyester paint and a RAL3003
red stripe.
- Rigid, hot dipped galvanized chassis.
- Unit lifting and handling via the base frame.
- State of the art design with hidden compressors, fans and
pump for perfect architectural integration.
- Side grilles as option to protect the unit during transportation
and against human aggressions.
High ef
fi
ciency multiscroll technology
- Exclusive Compliant Scroll® design with both axial and radial
compliance to increase compressor operation tolerance
to liquid refrigerant, substantially improving durability and
reliability.
- Motor cooled by suction gas.
- Motor protection device against high temperature or over
current situations.
- Discharge non-return valve.
- Crankcase heater as standard on heat pump and optional
with winter operation down 0°C for cooling only units.
- Direct on line start.
- Low noise scroll compressors insulated with a compressor
acoustic jacket.
- Compressors mounted on high effi ciency cellular polyurethane
vibration absorbers.
Advanced condenser fan design
Fan-motor assembly using external rotor technology associated
with OWLET high performance aluminum fan blades of the latest
fan technology to improve energy consumption and airfl ow rate
on the outdoor coils while reducing sound power level. Axial fans
speed are 700 or 900 rpm according to models, direct coupling,
with available static pressure up to 75 Pa as standard.
Pressure version for size 100 to 230 : speed axial fans are
1450 RPM, direct coupling, with available static pressure up to
250 Pa. For small sizes, COMPACTAIR is the appropriate unit
for technical room.
.
Heat exchanger
Made of copper tubes and aluminum corrugated swirl fi ns, the
coil heat exchanger are designed to maximize the output.
Refrigerant circuit:
AIRCOOLAIR outdoor units operate with R410A refrigerant.
For cooling only outdoor units, each circuit includes in stan-
dard:
- High pressure switch with automatic reset.
- Low and high pressure transducers.
On heat pumps outdoor units, each circuit includes in addition,
as standard :
- Four-way valve
- Liquid receiver
- Thermostatic expansion valve
- Filter drier
Each refrigerant circuit is pressure and leak tested with a
Hydrogen/Nitrogen mixture, and vacuumed before being charged
with nitrogen. All units are then subjected to a complete functional
and operational run test to guarantee perfect sealing before
leaving the factory.
Electrical box:
- Unit wiring in compliance with standard EN 60204-1.
- IP54 water protection.
- Circuit breaker protection for compressors and fans.
- Compressor and fan working contactors.
- Terminal block and wiring for power supply to the unit.
- Power supply 400V/3/50Hz without neutral except for size
20S with neutral.
