2.01 CHILLER MATERIALS AND COMPONENTS
A. General: Install and commission, as shown on the schedules and plans, factory assem-
bled, charged, and tested air cooled scroll compressor chiller(s) as specified herein.
Chiller shall be designed, selected, and constructed using a refrigerant with Flamma-
bility rating of “1”, as defined by ANSI/ASHRAE STANDARD - 34 Number Designation
and Safety Classification of Refrigerants. Chiller shall include, but is not limited to a
complete system with a single refrigerant circuit 35 tons (123kW) and below, and not
less than two refrigerant circuits above 35 tons (123kW), scroll compressors, direct
expansion type evaporator, air-cooled condenser, refrigerant, lubrication system, inter-
connecting wiring, safety and operating controls including capacity controller, control
center, motor starting components, and special features as specified herein or required
for safe, automatic operation.
B. Cabinet: External structural members shall be constructed of heavy gauge, galvanized
steel coated with baked on powder paint which, when subject to ASTM B117, 1000
hour, 5% salt spray test, yields minimum ASTM 1654 rating of “6”. Add Wire Panels
of heavy gauge, welded wire-mesh, coated to resist corrosion, to protect condenser
coils from incidental damage and restrict unauthorized access to internal components.
Factory installed.
2.02 COMPRESSORS
Compressors: Shall be hermetic, scroll-type, including:
1. Compliant design with axial and radial sealing.
2.
Refrigerant flow through the compressor with 100% suction cooled motor.
3. Large suction side free volume and oil sump to provide liquid handling capability.
4. Compressor crankcase heaters to provide extra liquid migration protection.
5. Annular discharge check valve and reverse vent assembly to provide low pressure
drop, silent shutdown and reverse rotation protection.
6. Initial Oil charge.
7. Oil Level sight glass.
8. Vibration isolator mounts for compressors.
9. Brazed-type connections for fully hermetic refrigerant circuits.
