EXPIRATION DATE:

22089 09/01/2024

GENERAL:

1. PACKAGED, SELF-CONTAINED UNIT CONSISTING OF COMPRESSOR,

AIR-COOLED CONDENSER, RECOVERY SYSTEM, TANK PRESSURE GAGES,

FILTER DRYER, AND VALVING THAT ALLOWS FOR SWITCHING BETWEEN

LIQUID- AND VAPOR-RECOVERY MODE.

2. RRS-1 & RRS-2 WILL OPERATE UNDER MANUAL CONTROL, AS NEEDED, FOR

CHILLER MAINTENANCE. MONITORING THROUGH BAS IS NOT REQUIRED.

REFRIGERANT RECOVERY SYSTEM -

SEQUENCE OF OPERATION

GENERAL:

1. THE CONDENSER WATER SYSTEM IS AN EXISTING SYSTEM COMPRISED

OF THREE COOLING TOWERS AND CONDENSER WATER PUMPS. SYSTEM

PUMPS P-2.1, P-2.2, AND P-2.3 ARE REPLACED AS PART OF THIS PROJECT

AND ARE ARRANGED IN LEAD/LAG/STANDBY CONFIGURATION. COOLING

TOWERS CT-1, CT-2 AND CT-3 ARE EXISTING TO REMAIN AND ARE

ARRANGED BY LEAD/LAG STANDBY. ROTATE DESIGNATIONS ON A

WEEKLY BASIS. PROVIDE NEW SEQUENCE OF OPERATION AS INDICATED

BELOW EXCEPT WHERE INDICATED TO BE EXISTING SEQUENCE TO

REMAIN IN SECTION 8 OF COOLING TOWER SEQUENCE OF OPERATION.

2. THE SYSTEM INCLUDES EXISTING TO REMAIN TOWER SUMP SWEEPER

AND FILTRATION SYSTEMS, METERED MAKEUP WATER CONNECTION,

LOW PRESSURE STEAM FOR FREEZE PROTECTION, AND WATER

TREATMENT. EXISTING CONTROL LOGIC FOR THESE ELEMENTS IS

EXISTING TO REMAIN.

3. UNDER NORMAL CONDITIONS, THE CENTRAL PLANT OPTIMIZATION (CPO)

PROGRAM WILL DETERMINE NUMBER OF PUMPS AND COOLING TOWERS

TO OPERATE, CONDENSER WATER TEMPERATURE SETPOINTS, AND

VARIABLE FREQUENCY DRIVE SPEED FOR COOLING TOWER FANS AND

PUMPS. WHEN CPO PROGRAM IS NOT ACTIVE, BAS SHALL CONTROL

CONDENSER WATER SYSTEM AS DESCRIBED BELOW. EXISTING

CONTROLS FOR THE BASIN HEATER, SWEEPING AND FILTRATION

SYSTEM, LOW TEMPERATURE TOWER BYPASS, CHEMICAL TREATMENT

SYSTEM, AND SYSTEM FILL SHALL REMAIN AND BE INTEGRATED INTO

CONTROLS PROVIDED ON THIS PROJECT.

4. THE CONDENSER WATER TEMPERATURES SHALL BE MAINTAINED AS

FOLLOWS:

CONDENSER WATER SUPPLY 85 DEG F MAXIMUM

CONDENSER WATER RETURN 96 DEG F

DESIGN AMBIENT CONDITIONS 95 DEG F DB / 78 DEG F WB

5. SYSTEM OPERATION OPERATES FULLY AUTOMATIC WITH MANUAL

OVERRIDES.

6. SYSTEM OPERATING STATUS AND SCHEDULES, TEMPERATURE

SETPOINTS, AND EQUIPMENT ALARM CONDITIONS SHALL BE MONITORED

AND ADJUSTED THROUGH DDC SYSTEM GRAPHICAL USER INTERFACE.

OPERATOR SHALL ALSO BE ABLE TO PERFORM ALL MONITORING AND

CONTROL OF THE CONDENSER WATER SYSTEM DIRECTLY FROM DDC

PANEL THROUGH FIELD INTERFACE.

EXISTING COOLING TOWERS (CT-1; CT-2; CT-3)

1. UNDER NORMAL CONDITIONS, COOLING TOWERS SHALL OPERATE ON A

LEAD/LAG/STANDBY BASIS. ROTATE LEAD/LAG/STANDBY ON A WEEKLY

BASIS WHEN CH-1 AND CH-2 ARE OPERATING TOGETHER, ONLY A SINGLE

COOLING TOWER AND CONDENSER WATER PUMP IS REQUIRED TO

OPERATE. ENERGIZE SECOND COOLING TOWER WHEN CH-3 OR CH-4 IS

ENERGIZED.

2. OPEN COOLING TOWER ISOLATION VALVE V-1E AND V-4E WHEN COOLING

TOWER IS ENABLED THROUGH BAS. OPEN V-3E AND CLOSE LINKED

VALVE V-2E TO DIRECT WATER THROUGH SPRAY NOZZLES. ONCE

ISOLATION VALVE IS PROVEN OPEN, START ASSOCIATED CONDENSER

WATER PUMP.

3. EXISTING CONTROLS FOR EACH TOWER INCLUDE A BASIN WATER

TEMPERATURE SENSOR. WHEN BASIN WATER TEMPERATURE EXCEEDS

75F FOR AN OPERATING COOLING TOWER, THE COOLING TOWER VFD

SHALL ENERGIZE AND MODULATE AS REQUIRED TO MAINTAIN SUPPLY

WATER TEMPERATURE OF 75F. WHEN VFD REACHES FULL SPEED, BASIN

WATER TEMPERATURE IS PERMITTED TO RISE TO 85F DESIGN SET

POINT. MINIMUM VFD SET POINT IS 18 HZ (ADJ).

4. ON A DROP IN SUPPLY WATER TEMPERATURE BELOW 75F (TS-23

ADJUSTABLE), DE-ENERGIZE THE COOLING TOWER FAN AND MODULATE

CHILLER BYPASS CONTROL VALVES V-9, V-10, AND V-11 TO MAINTAIN 65F

MINIMUM SUPPLY WATER TEMPERATURE AS SENSED BY CONDENSER

WATER SUPPLY TEMPERATURE SENSORS TS-16, TS-18, TS-20, AND TS-22.

CPO CONTROLS MAY OVERRIDE 65 F SET POINT AND ALLOW LOWER

CONDENSER WATER TEMPERATURES BASED ON CHILLER OPERATING

PERFORMANCE.

5. WHEN A TOWER IS OFF, CLOSE VALVE V-1E AND V-4E AND OPEN LINKED

VALVES V-2E AND V-3E TO 50% TO ALLOW WATER TO DRAIN FROM THE

RISER TO SPRAY HEADS.

6. ANY COOLING TOWER MAY BE COMMANDED OFF THROUGH BAS. WHEN

COMMANDED OFF, EXISTING TO REMAIN BAS CONTROL LOGIC SHALL

SIGNAL PACKAGED COOLING TOWER CONTROLS DE-ENERGIZE FAN.

EXISTING WATER LEVEL CONTROLS AND BASIN FREEZE PROTECTION

MUST REMAIN OPERATIONAL. CLOSE TOWER ISOLATION CONTROL

VALVES V-1E AT THE CWS CONNECTION TO EACH COOLING TOWER.

7. DDC WILL MONITOR AND ANNUNCIATE A GENERAL COOLING TOWER

PACKAGED CONTROL ALARM.

8. FILTRATION SYSTEM, COOLING TOWER WATER MAKE-UP, AND BASIN

HEATERS SHALL OPERATE IN ACCORDANCE WITH EXISTING BAS LOGIC

AS DESCRIBED BELOW.

A.FILTRATION SYSTEM SHALL RUN CONTINUOUSLY AND BE MONITORED

BY BAS SYSTEM. WHEN ACTIVATED, PUMP TFP-1 SHALL OPERATE AND

VALVE V-5E AND VALVE V-6E SHALL OPEN TO ONE TOWER BASIN

WHILE THE VALVES V-5E AND V-6E TO THE OTHER BASINS SHALL

REMAIN CLOSED. BASIN SERVED BY FILTRATION SYSTEM SHALL

ROTATE EVERY 24 HOURS.

B.STEAM CONTROL VALVE V-7E SHALL OPEN WHEN SUMP

TEMPERATURE FALLS BELOW 45F AND SHALL CLOSE WHEN SUMP

TEMPERATURE RISES ABOVE 50F.

C.CONDENSER WATER MAKE UP VALVE V-8E SHALL OPEN WHEN SUMP

WATER LEVEL DROPS BELOW LOW LEVEL SET POINT AND CLOSE

WHEN WATER LEVEL RISES TO HIGH LEVEL SET POINT.

D.CONDENSER WATER BLOWDOWN VALVE V-9E SHALL OPERATE

THROUGH EXISTING BAS WATER TREATMENT CONTROLS TO MAINTAIN

WATER QUALITY AS DETERMINED BY WATER TREATMENT EQUIPMENT.

9. UPON A COOLING TOWER FAILURE, AS SENSED BY COOLING TOWER

VFD, EACH REMAINING COOLING TOWER SHALL BE ADVANCED ONE

POSITION AND SIGNAL ALARM TO BAS.

CONDENSER WATER PUMPS (P-2.1; P-2.2; P-2.3)

1. PUMPS SHALL OPERATE IN A LEAD/LAG/STANDBY CONFIGURATION.

ROTATE PUMP DESIGNATIONS ON AN WEEKLY BASIS. PUMPS MUST BE

CONTROLLED TO OPERATE WITH CHILLERS AS ASSIGNED THROUGH THE

BAS. THE PIPING AND VALVING PERMITS ANY PUMP TO OPERATE WITH

ANY CHILLER. SYSTEM WILL BE VARIABLE FLOW UNDER CONTROL OF

CPO PROGRAM AND CONSTANT FLOW WHEN CPO PROGRAM IS

DISABLED.

2. START LEAD CONDENSER WATER PUMP WHEN LEAD CHILLER ISOLATION

VALVE LIMIT SWITCH IS PROVEN OPEN.

3. MODULATE LEAD PUMP UNDER VFD CONTROL TO MAINTAIN ASSOCIATED

CHILLER DESIGN FLOW RATE BASED ON PRESSURE DIFFERENCE

ACROSS CHILLER.

4. START LAG CONDENSER WATER PUMP WHEN BAS CALLS FOR

ADDITIONAL FLOW AS DESCRIBED IN CHILLER SECTION ABOVE. LEAD

PUMP IS DESIGNED TO PROVIDE ADEQUATE COMBINED FLOW FOR CH-1

AND CH-2.

5. WHEN OPERATING CONDENSER WATER PUMP FAILS AS SENSED BY

PUMP VFD, ANNUNCIATE ALARM TO CENTRAL BAS SYSTEM GRAPHICAL

USER INTERFACE AND ACTIVATE STANDBY PUMP. IF STANDBY PUMP

FAILS, DEACTIVATE THE ASSOCIATED CHILLER AND COOLING TOWER

AND ANNUNCIATE AN ALARM AT CENTRAL WORKSTATION GRAPHICAL

INTERFACE.

6. CONDENSER WATER SYSTEM SHALL BE BALANCED FOR TAB WITH CH-1,

CH-2, AND CH-4 OPERATIONAL AT DESIGN FLOW.

7. VFD TURNDOWN UNDER CPO CONTROL SHALL BE LIMITED BY MINIMUM

ALLOWABLE FLOW THROUGH THE CHILLER AS MEASURED BY EACH

CHILLER FLOW METER. MINIMUM FLOW SETPOINT SHALL BE

COORDINATED WITH PROVIDED CHILLER. BASIS OF DESIGN SETPOINT

FOR CHILLERS CH-1 AND CH-2 MINIMUM FLOW IS 390 GPM, AND FOR

CHILLERS CH-3 AND CH-4 MINIMUM FLOW IS 720 GPM.

8. CONDENSER WATER PUMP MUST BE ENERGIZED PRIOR TO COOLING

TOWER FAN AND CHILLER START. CONDENSER PUMP MUST NOT START

UNTIL CONDENSER WATER SUPPLY CONTROL VALVE FOR ASSOCIATED

TOWER (V-1E) AND CHILLER (V-2, V-4, V-6, V-8) IS PROVEN OPEN.

PROVIDE FLOW SWITCHES AS INDICATED TO ASSURE FLOW PRIOR TO

CHILLER OPERATION.

CONDENSER WATER - SEQUENCE OF OPERATION

GENERAL:

1. WHEN THERE IS A "HIGH REFRIGERANT LEVEL" ALARM IN EITHER ROOM A-123 OR D-129, OPEN EXHAUST AND OUTSIDE AIR DAMPERS SERVING ROOM AND RUN FAN CONTINUOUSLY AND ENERGIZE STROBES LOCATED AT EACH ROOM ENTRANCE. OPERATE IN THIS MANNER UNTIL OPERATOR STOPS FAN AND STROBES DE-ENERGIZE WHILE DAMPERS IN THE OTHER ROOM REMAIN CLOSED. (D-1 AND D-2 FOR A-123 AND D-3, 4, AND 5 FOR ROOM D-129).

2. WHEN THE "HIGH REFRIGERANT LEVEL" ALARM OCCURS IN ROOM D-129, DE-ENERGIZE EXISTING TRANSFER FAN AND EXISTING EXHAUST FAN. SEE MD400s AND M400 DRAWINGS FOR LOCATION OF EXISTING FANS. FANS MUST

BE MANUALLY RESET BY OPERATOR.
