UNIT DESCRIPTION
FRAME
All FSW units are made from galvanised thick sheet metal, painted with polyurethane powder
enamelat 180°C to ensure the best resistance against the atmospheric agents. The frame is self-
supporting
REFRIGERANT CIRCUIT
The refrigerant gas used in these units is R410A. The refrigerant circuit is made in according to ISO
97/23 concerning welding procedures and PED regulation.
The refrigerant circuit includes:
•
filter drier.
•
schrader valves form maintenance and control.
•
capillary expansion.
•
compressor.
CONDENSER AND EVAPORATORS
FINNED PACK
It consist of copper tubes mechanically expanded into aluminium or copper fins provided with full
collars that allow their regular spacing. The best heat transmission is guaranteed by the fin collars that
completely cover the tubes.
FINS
They are manufactured by high precision pressing of aluminium, aluminium epoxy painted, copper or
pretinned copper sheets. The fin shape is slightly corrugated in order to improve the heat exchange
transmission coeffi cient without heavily affecting the air pressure drop. Furthermore a good water
draining is assures and the inside dust accumulation is avoided.
TUBES
For the heat exchangers high quality copper tubes are used. The tubes are suitable for the majority of
the primary refrigerants in both cold and warm working conditions.
COMPRESSOR
The compressor is rotative type.
The characteristics of the compressor are the follow:
1.
High efficiency for saving energy consumption
2.
Low sound level
，
quiet operation
3.
Applied HFC refrigerant for protecting environment
4.
High reliability, long lifetime.
FANS
Centrifugal fan type.
