Condenser:
Application
Engineering Remarks:
The application range of a condensing unit depends on
a number of conditions. Therefore, the refrigeration
performance data contains special remarks in which case,
additional ventilation, or a limitation of the suction
gas temperature is required. If these recommendations
are adhered to, a continuous operation of the condensing
units are possible within the range for which performance
data is available.
Data sheets are available for each compressor model
and aircooled condensing unit. They contain considerably
more detailed thechnical information than this leaflet.
The Data sheets for the respective compressors used
will provide the information required for the selection
of water cooled condensing units, application range,
electrical data etc.
COOLRITE
Standard Air Cooled Condensers: shall be made of
zincor primered steel sheet coated with oven baked fine
enamels. All units shall have the best protection against
rust and corrosion.
Compressors
shall be hermetic or semihermetic type, designed by
International companies, for high energy efficiency
for refrigeration applications. Rugged, compact construction
for heavy duty usage.
Coils
shall be made of seamless copper tubes, expanded
on aluminium fins, and tested at 28 bar (400 psi). Aluminium
fins are normally spaced at 12 fpi.
Fans
shall be of radial propeller type, statically and dynamically
balanced, with heavy gauge protective wire guard specially
designed for large air flow with low static head pressure.
Large diameter, low RPM, low noise, maintenance-free
quality.
Motors shall be water proof totally enclosed
type with maintenance-free bearings or long life solid
lubricant reserve, additional moisture protection suitable
for outdoor conditions, single or multispeed single
phase permanent split capacitor, or single speed 3 phases
type, direct drive or belt drive arrangement. Motors
are suitable for horizontal and vertical working position,
with internal built-in thermal protection, low speed,
and low noise. In accordance with most European and
American Electric Norms.
Easy Installation: COOLRITE units are completely
factory tested, dried, filled with R22 and sealed. All
units have one shot quick connectors or valve with soldering
copper pipe outlets. Gas circuits have permanent access
valves.
Electric
Junction board shall be color coded and wires identified
for easy field connections and maintenance. It includes
compressor and fan motor contactors, extra thermal overload
protection, high/low voltage protection relay with compressor
restart delay, high & low pressure cut off protection,
compressor crankcase heater, circuit fuse breakers and
coded terminals. Four way reversing valve & deicer
thermorelay for Heat Pump applications.
Access
to all internal parts for cleaning or maintenance
needs only loosening of a few screws to remove any panel.
All parts can be easily removed & replaced.
Piping shall be made of brazed seamless
copper tube including sight glass and filter dryier,
and a receiver and an accumulator if necessary.
Water cooled Condensing Units:
Are equiped with cleanable shell and tube
condensers with removable end plates instead of the
coil and for arrangements.
Evaporator:
COOLRITE Standard Unit Cabinet shall
be made of zincor primered steel sheet coated with oven
baked fine enamels. All units shall have the best protection
against rust and corrosion.
Coil shall be made of brazed seamless copper
tubes, expanded on aluminium fins, and tested at 28
bar (400psi). Aluminium fins are spaced according to
the capacity of the evaporator.
Coils shall have electric heaters to prevent icing of
the coil. Integral Drain run under the the coil and
fans is suitable for proper condenser drainage.
Fans
shall be of radial propeller type, statically and dynamically
balanced, with heavy gauge protective wire guard specially
designed for large air flow with low static head pressure.
Large diameter, low RPM, low noise, maintenance-free
quality fan are used.
Insulation All standard units shall
ce thermally and accoustically insulated with polyrethane
foam or asphalt coated fiber glass panels.
Integral drain pan under the coil and Fans is suitable
for propper condensate drainage.
Filter. slots are standard in all units, ½ inch
disposable filter is normally provided, cleanable filters
are also available on request.
Motors shall be water proof enclosed
type with maintenance-free bearings or long life solid
lubricant reserve, suitablefor outdoor conditions. Single
or multispeed single phase permanent split capacitor,
or single speed 3 phase type, direct drive or belt drive
arrangement. Motors are suitable for horizontal and
vertical working positions, with internal built-in thermal
protection, low speed, and low noise, in accordance
with most European and American Electric Norms.
