General; Compressor; Evaporator; Air Cooled Condensers - Airwell CDN 205 Manual De Instalación Y De Mantenimiento

GENERAL

The condensing unit CDN 205 to 905 offer 8 models with cooling capacities from 19 to 83 kW allowing to suit,
in this capacity range, the air conditioning applications required for tertiary or industrial sectors.
In a compact shape, these condensing units have a very small space requirement.
The units are suitable for outdoor installation (on a roof or directly on ground) made from galvanised steel coated
with powder-based paint.
All units are completely assembled in the factory with all interconnecting refrigerant piping and internal wiring ready
for field installation. After assembly, a full run test is also performed in the factory to verify that the refrigerant circuit
operates correctly. They are delivered with their complete oil charge, nitrogen charge.
Air cooled condensing units are suitable for air conditioning applications requiring the use of direct expansion coils.
The thermal expansion valve, sight glass and connecting pipes will be supplied by others.

COMPRESSOR

Compressor is of hermetic Scroll type.
The compressor motor, refrigerant gas cooled type, is equipped with automatic reset internal thermal protection.
The compressor is mounted on rubber anti vibration pads.

EVAPORATOR

Evaporator is provides by the installer. Its capacity must correspond to that of condensing unit for the correct
operation of installation.

AIR COOLED CONDENSERS

Condenser coils consist of seamless copper tubes arranged in a staggered row pattern. Each coil is mechanically
expanded into aluminium fins with full fin collars.

CONDENSER FAN AND MOTOR

The fan is of the direct drive Helicoidal type. The motor is equipped with an internal heat overload protection with
an automatic reset function. The rotational speed of the fan or fans is managed by a condensing pressure regulator
allowing for operation at low outdoor temperatures (refer to Operating Limits).

ELECTRICAL PANEL

All electrical equipment required for proper unit operation is located in a weatherproof electrical panel with access
on the front of the unit.
The CE compliance of electrical panel is assured by an access panel fixed by bolts. The electrical panel has a main
switch with externally lockable handle, power contactors, compressor thermal overload, control circuit fuses, high
pressure cut-out, antishort cycle time delay and electrical junction blocks for power and control circuits. Indoor
unit regulation is not supplied.
