Compressor and Motor
The unit is equipped with a semihermetic, direct-drive, 3600-rpm
(3000 rpm @ 50 Hz) rotary compressor that includes a capacity
control slide valve, oil sump heater, and differential pressure
refrigerant oil flow system. Four pressure-lubricated, rolling-element
bearing groups support the rotating assembly.
The motor is a suction gas-cooled, hermetically sealed, two-pole,
squirrel cage induction-type.
Evaporator and Condenser Shells are carbon steel plate. The
evaporator and condenser are designed, tested, and stamped in
accordance with ASME Code for refrigerant-side/ working-side
pressure of 200 psig.
All tube sheets are made of carbon steel; tubes are mechanically
expanded into tube sheets and mechanically fastened
to tube supports. Evaporator tubes are 1.0-inch (25.4 mm)
diameter and condenser tubes are 0.75-inch (19.05 mm) diameter.
Both types can be individually replaced. Standard tubes are
externally finned, internally enhanced seamless copper with
lands at all tube sheets. |
