Refrigerant enters the compressor at the suction connection and flows around the motor’s housing and enters at the
bottom side through the openings.
Oil droplets separate from the refrigerant and fall into the oil sump.
All suction refrigerant passes through the electrical motor, ensuring full motor cooling.
After that the refrigerant enters the scroll elements.
3.3.2 Condenser Coil
Condenser coils are corrugated fin and tube type; constructed of seamless 3/8" diameter inner grooved copper tubes,
mechanically bonded to enhanced louvered aluminum fins for maximum heat transfer efficiency. As the fins have full self
spacing collars which completely cover each tube. The staggered tube design improves the thermal efficiency. End
plates support sheets are heavy gauge galvanized steel, formed to provide structural strength. Each coil is pressure
tested in the factory at not less than 450 psi air pressure. Finally the coils are coated with thermo guard coating for
protection against seashore salty and corrosive environments.
3.3.3 Condenser Fan
Condenser fans are constructed of die cast aluminum blades/hubs with direct driven motors. All fans are statically and
dynamically balanced to operate at minimum noise and vibration. Fan blades are designed with appropriate pitch angle
which result in maximum airflow through the condenser coil.
3.3.4 Condenser Fan Motor
Condenser fans, the impeller and motors are so constructed to form an integral unit. All fan motors shall be three phase
with class ‘’F’’ winding insulation and ball bearings for high ambient application. These fan motors are of totally enclosed
air over type (TEAO) with inherent thermal protection of automatic reset type & specially designed for outdoor applica-
tions.
3.3.5 Evaporator Coil
Coils are made with corrugated fins and seamless ½’’ diameter copper tubes mechanically bounded enhanced fins
enable maximum heat transfer efficiency. Evaporator is tested in the factory at 300 PSI air pressure. Finally the coils are
coated with thermo guard coating for protection against seashore salty and corrosive environments. Coils conform to ARI
standard 410.
3.3.6 Evaporator Fan
Heavy-duty high pressure backward radial fan is capable of supplying required airflow & static pressure. The fan dis-
charge outlet can be connected to a flexible pre-conditioned delivery hose (supplied along with unit). Flexible duct is
constructed by two-ply, abrasion resistant fabrics or PVC coated fabrics and is stowed inside the storage box, when not
in use.
