2.02 COMPRESSORS

A. Compressors: Shall be hermetic, scroll-type, including:

1. Compliant design for axial and radial sealing

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.

10. Compressor motor overloads capable of monitoring compressor motor tempera-

ture. Provides extra protection against compressor reverse rotation, phase-loss and

phase-imbalance.

2.03 REFRIGERANT CIRCUIT COMPONENTS

Each refrigerant circuit shall include: a discharge service ball type isolation valve, high

side pressure relief, liquid line shutoff valve with charging port, low side pressure relief de-

vice, filter-drier, solenoid valve, sight glass with moisture indicator, thermostatic expansion

valves. [

Option

: electronic expansion valves], and flexible, closed-cell foam insulated

suction line and suction pressure transducer.

2.04 HEAT EXCHANGERS

A. Evaporator :

1. Evaporator shall be brazed-plate stainless steel construction capable of refrigerant

working pressure of 450 psig (3103 kPa) and liquid side pressure of 150 psig (1034

kPa).

2. Brazed plate heat exchangers shall be UL listed.

Exterior surfaces shall be covered with 3.4” (19mm), flexible, closed cell insulation,

thermal conductivity of 0.26k ([BTU/ HR-Ft2 -°F]/in.) maximum.

Water nozzles shall be provided with grooves for field provided ANSI/AWWA C-606

mechanical couplings.

Evaporator shall include vent and drain fittings and thermostatically controlled heat

ers to protect to -20°F (-29°C) ambient in off-cycle.
