General Features
The rooftop unit shall consist of compressors, fan
motors, condenser coils, evaporator coil, expansion
valves, refrigerant piping and electrical components.
The unit shall be assembled, complete with internal
wiring, fully charged with R-22 refrigerant and undergo
strict testing & quality check before delivery.
The rooftop unit shall be capable of operating from
19°C to 54°C ambient temperature without failure.
Compressor
Compressor shall be hermetically sealed, high
ef
fi
ciency and low noise scroll type compressor.
The compressor shall be equipped with an internal
overload protection.
Evaporator Coil and Condenser Coil
Evaporator coil and condenser coil shall be
manufactured from seamless inner grooved copper
tubes, which are mechanically bonded to aluminium
fi
ns.
All coils shall be tested against leakage by Nitrogen
holding at 609psig and highly precise Helium leak
test at 235psig.
Evaporator Fan & Motor
Condenser coils are manufactured from seamless
inner grooved copper tubes mechanically bonded to
aluminium
fi
ns to ensure optimum heat transfer. All
coils are tested against leaks by Nitrogen holding
at 609psig and highly precise Helium leak test at
235psig.
Condenser Fan & Motor
Condenser Motor shall be of IP55 insulation class
rating and is equipped with dust proof bearing.
Condenser fan shall be direct driven propeller type.
Refrigerant Circuit
The unit shall be able to operate at part loading
depending on the requirement of the application.
Each refrigerant circuit shall have an independent
Thermal Expansion Valve (TXV),
fi
lter drier and High
/ Low Pressure Switch.
There shall be additional valves provided for site
installation of Pressure Gauge and Low Ambient Kit.
Casing / Structure
The casing and structure of the unit shall be made
from zinc coated galvanized steel sheets and
further coated with an electrostatic powder for better
resistance against the weather.
Filter
A 2 inch
fi
lter rail shall be provided in the unit for site
installed
fi
lter.
Control Panel
The controller in the unit shall be either mechanically
controlled with relays, contactors and timers or
electronically controlled with microcontroller that
handles the operation of the unit.
