CENTRIFUGAL WATER CHILLERS 23 64 16 - 16BROOKHAVEN COLLEGE CHILLER ADDITION ADDEDNUM #1 08/22/17

a. Vane operated to actuate a double-pole, double-throw switch, with one pole field wired to the chiller control panel and the other pole field wired to the DDC system for HVAC.

b. Contacts: Platinum alloy, silver alloy, or gold-plated switch contacts with a rating of 10 A at 120-V ac.

c. Pressure rating equal to pressure rating of heat exchanger.d. Construct body and wetted parts of Type 316 stainless steel.e. House switch in a NEMA 250, Type 4 enclosure constructed of die-cast aluminum.f. Vane length to suit installation.

3. Pressure-Differential Switches:

a. Construction: Wetted parts of body and trim constructed of Type 316 stainless steel.

b. Performance: Switch shall withstand, without damage, the full-pressure rating of the heat exchanger applied to either port and exhibit zero set-point shift due to variation in working pressure.

c. Set Point: Screw type, field adjustable.d. Electrical Connections: Internally mounted screw-type terminal blocks.e. Switch Enclosure: NEMA 250, Type 4.f. Switch Action: Double-pole, double-throw switch, with one pole field wired to the

chiller control panel and the other pole field wired to the DDC system for HVAC.

B. Vibration Isolation:

1. Chiller manufacturer shall furnish vibration isolation for each chiller.2. Neoprene Pad:

a. Two layers of 0.375-inch-thick, ribbed- or waffle-pattern neoprene pads separated by a 16-gage, stainless-steel plate.

b. Fabricate pads from 40- to 50-durometer neoprene.c. Provide stainless-steel square bearing plate to load the pad uniformly between 20

and 40 psig with a 0.12- to 0.16-inch deflection.

2.14 SOURCE QUALITY CONTROL

A. Perform functional run tests of chillers before shipping.

B. Factory Performance Testing:

1. Factory performance test chillers, before shipping, according to AHRI 550/590.2. Test the following conditions:

a. Design conditions indicated.b. Reduction in capacity from design to minimum load in steps of 10 with condenser

fluid at design conditions.c. Reduction in capacity from design to minimum load in steps of 10 with varying

entering condenser-fluid temperature from design to minimum conditions in 5 deg F increments.

d. At five point(s) of varying part-load performance to be selected by Owner at time of test.

3. Allow Owner and Engineer access to place where chillers are being tested. Notify Owner in writing at least 14 days in advance of testing.

HVAC SYSTEM DESCRIPTION:AT THE COMPLETION OF THE PROJECT, THE CHILLED WATER SYSTEM WILL CONSIST OF THREE WATER-COOLED

CHILLERS (CH-1, CH-2, AND CH-3), THREE PRIMARY CHILLED WATER PUMPS (PCHP-1, PCHP-2, AND PCHP-3), AND TWO

SECONDARY CHILLED/HEATING WATER PUMPS. CH-1 IS A 700-TON CHILLER, CH-2 IS A 300-TON CHILLER, AND CH-3 IS A 400-TONCHILLER.
