(E)WATER METER

DESIGN INTENT

1. TWO CHILLERS, TWO COOLING TOWER, TWO PRIMARY CHILLED WATER PUMPS, TWO CONDENSER

WATER PUMPS ARE REQUIRED TO MEET THE BLOCK LOAD.

1.1. ONE CHILLER REQUIRES ONE COOLING TOWER AND ONE CONDENSER WATER PUMP. HOWEVER, THE MOST EFFICIENT SINGLE CHILLER OPERATION USES 2 COOLING TOWERS AND ONE

CONDENSER WATER PUMP.

1.2. TWO CHILLERS REQUIRES TWO COOLING TOWER AND TWO CONDENSER WATER PUMPS,

1.3. THEREFORE THIS DESIGN RUNS TWO COOLING TOWERS WITH THE EXISTING TWO 400 TON

CHILLERS.

2. TO REDUCE ENERGY USE, ALL COOLING TOWERS SHOULD OPERATE WITH A SINGLE CHILLER AND SINGLE CONDENSER WATER PUMP WHEN THE OUTSIDE AIR TEMPERATURE IS ABOVE 55°F. IN ORDER TO REDUCE THE COOLING TOWER APPROACH AND INCREASE CHILLER EFFICIENCY, THIS DESIGN OPERATES ALL TOWERS AT 70% SPEED THAT RESULTS IN TOTAL TOWER BHP OF 34% OF A SINGLE

TOWER MOTOR.

3. FREE COOLING - REQUIRES ONE COOLING TOWER, ONE FREE-COOLING CONDENSER WATER PUMP, ONE FREE COOLING CHILLED WATER PUMP, ONE 200 TON PLATE FRAME HEAT EXCHANGER. FREE

COOLING IS ACTIVE WHEN OUTDOOR AMBIENT TEMPERATURE IS BELOW 47°F AND OFF ONCE

TEMPERATURE RISES ABOVE 54°F.

2. EQUIPMENT PAIRINGS FOR LEAD/LAG: (CHILLER), (CONDENSER PUMP), (PRIMARY PUMP)

2.1. CH-1, CWP-1, CHP-1

2.2. CH-2, CWP-2, CHP-2

2.3. CWP-3 = STANDBY PUMP FOR EITHER CH-1 OR CH-2

2.4. IN THE EVENT OF EQUIPMENT FAILURE, THERE ARE MANUAL VALVES TO CHANGE EQUIPMENT

PAIRINGS. PROVIDE MANUAL OVERRIDES ON THE OWS.

3. EQUIPMENT FOR FREE COOLING

3.1. LEAD COOLING TOWER

3.2. CHILLED WATER PUMP - CHP1D

3.3. CONDENSER WATER PUMP - CWP2D

3.4. HEAT EXCHANGER - HX-1

LEAD/LAG SELECTION

1. PRIOR TO STARTING THE CHILLED WATER SYSTEM THE OPERATOR SHALL SELECT THE EQUIPMENT

LEAD AND LAG ORDER.

2. PUMPS, AND COOLING TOWERS INPUT AS "OUT OF SERVICE" WILL BE SKIPPED OVER IN THE STARTING

AND STOPPING SEQUENCE

EQUIPMENT ROTATION: AUTOMATICALLY ALTERNATE THE FOLLOWING TO EQUIPMENT PAIRINGS TO EQUALIZE THE RUN TIMES, WITH A MINIMUM OF ONCE PER WEEK. THE LIST BELOW SHOWS TYPICAL

EQUIPMENT PAIRINGS:

CH-1, CWP-1, CHP-1,

CH-2, CWP-2, CHP-2

CT-1A, CT-1B

CWP-3 = STANDBY EQUIPMENT

COOLING

1. EXISTING CHILLER START UP SEQUENCE IS TO BE MAINTAINED.

2. CHILLER HEAD PRESSURE CONTROL SHALL MODULATE CONDENSER WATER BYPASS VALVE V-3

OUTSIDE OF THE BAS. PROVIDE VALVE PILOT POSITIONER ON VALVE V-3 AND INDICATE VALVE

POSITION ON OWS GRAPHIC.

3. CONDENSER PUMP VFD: LEAD CONDENSER PUMP VFD BALANCED TO PROVIDE 1,000 GPM.

4. CONDENSER WATER SUPPLY TEMPERATURE, AS SENSED BY SENSOR TS-2, FLOATS BETWEEN HIGH LIMIT OF 83°F AND LOW LIMIT OF 60°F. PROVIDE A TIME DELAY, INITIALLY SET FOR 1 MINUTE, BETWEEN

COOLING TOWER STARTS.

5. WHEN OUTSIDE AIR TEMPERATURE RISES ABOVE 55°F, OPEN BOTH LAG TOWER VALVES V-1 AND V-2 AND EQUALIZER VALVE V-5 AND ENABLE BOTH TOWER CONTROLS. OPERATE ALL TOWER FAN VFDS AT 70% SPEED PROVIDED THAT CONDENSER WATER TEMPERATURE AT TS-2 IS BETWEEN HIGH AND LOW LIMITS. UPON A FALL IN TEMPERATURE AT TS-2 BELOW LOW LIMIT SETPOINT, TOWER VFDS SHALL

DECREASE SPEED.

6. WHEN FANS ARE AT MINIMUM SPEED FOR 15 MINUTES AND CONDENSER WATER RETURN

TEMPERATURE AT TS-2 FALLS TO 55°F, DISABLE ONE TOWER.

7. WHEN OUTSIDE AIR TEMPERATURE FALLS BELOW 55°F, A SINGLE COOLING TOWER FAN IS OPERATING, CLOSE LAG VALVE V-1, V-2, AND V-5. LEAD TOWER VFD SHALL OPERATE 20% HIGHER SPEED THAN

OPERATING CHILLER KW PERCENTAGE, SUBJECT TO CONDENSER WATER TEMPERATURE SENSOR

TS-2 HIGH AND LOW LIMITS. OPERATING TOWER VFD SHALL BE AT 100% SPEED WHEN OPERATING CHILLER KW PERCENTAGE IS BETWEEN 80 AND 100%. PROVIDE A TIME DELAY, INITIALLY SET 1 MINUTE, BETWEEN STARTS.

8. WHEN BOTH TOWERS OPERATE, CONTROL ALL VFDS AT THE SAME SPEED UNLESS OTHERWISE

NOTED.

WATER SIDE ECONOMIZER

1. FREE COOLING MODE: ON A FALL IN OUTSIDE TEMPERATURE BELOW 47°F AND A CALL FOR CHILLED WATER, VALVE V-1, V-2, V-4 AND V-5 SHALL OPEN. UPON CONFIRMATION THAT VALVES V-4 AND V-5 ARE OPEN, START ASSOCIATED PUMPS. FREE COOLING MODE SHALL BE ACTIVE UNTIL OUTSIDE AIR TEMPERATURE EXCEEDS 54°F. IF THERE IS NO CHILLED WATER DEMAND, BASED ON AHU CHILLED WATER VALVE POSITION, OR OUTSIDE TEMPERATURE IS ABOVE 54°F, THE REVERSE SHALL OCCUR.

2. LEAD COOLING TOWER CELL FAN SPEED SHALL MODULATE TO MAINTAIN SETPOINT OF CONDENSER WATER TEMPERATURE TRANSMITTER TS-2, INITIALLY SET 43 DEGREES F. PROVIDE A TIME DELAY, INITIALLY SET 10 MINUTE, BETWEEN STARTS OF COOLING TOWER MOTORS, SO THAT THERE ARE

MAXIMUM 6 STARTS PER HOUR.

FREEZE PROTECTION

1. BASIN HEATERS, SET TO MAINTAIN 38 °F, SHALL OPERATE WITH SELF CONTAINED CONTROLS.

2. FILL FREEZE PROTECTION: WHEN OUTSIDE AIR TEMPERATURE FALLS BELOW 40 °F, STOP OPERATING TOWER FAN EVERY TWO HOURS. AFTER A 1 MINUTE DELAY, OPERATE FAN IN REVERSE AT HALF

SPEED FOR 15 MINUTES. AFTER A 1 MINUTE TIME DELAY, ENABLE LEAD TOWER TO START.

COOLING TOWER MAKE-UP

1. ON A FALL IN TOWER WATER LEVEL, AS SENSED BY ASSOCIATED ELECTRIC WATER LEVEL

CONTROLLER EWL-1, MAKEUP VALVE V-6 SHALL OPEN. ON A RISE IN WATER LEVEL, THE REVERSE

SHALL OCCUR. EWL-1 SHALL BE IN CONTROL FOR ALL TWO CELLS.

POWER FAILURE - AUTOMATIC RESTART

1. LOSS AND RESTORATION OF POWER TO PLANT SHALL BE DETECTED BY THE BAS THROUGH LOSS OF

LOCAL FIELD PANEL OPERATION.

2. UPON RESTORATION OF POWER, DRIVE ALL VALVES TO NORMAL POSITIONS. THE BAS SHALL AUTOMATICALLY RESTART EQUIPMENT THAT WAS IN OPERATION PRIOR TO THE POWER FAILURE.

IMPLEMENT SEQUENCE FOR THE MODE MOST RECENTLY SELECTED. IF THE EQUIPMENT DOES NOT

START, IMPLEMENT PROCEDURE FOR EQUIPMENT FAILURE.

PLANT OPERATION - EQUIPMENT FAILURE

1. IF ANY PIECE OF EQUIPMENT FAILS TO START FOR WHATEVER REASON, THE BAS SHALL

AUTOMATICALLY IMPLEMENT THE NORMAL SEQUENCE TO START THE LAG EQUIPMENT. ADDITIONALLY, AN ALARM SHALL BE INDICATED AT THE OWS.

BASIN SWEEPER FILTRATION SKID

1. PUMP SHALL OPERATE WITH OPERATION OF CONDENSER WATER PUMPS AND FREE COOLING PUMP

CWP-1, CWP-2, CWP-3, OR CWP2D.

2. MOTOR RUN TIME: INDICATE TOTAL PUMP MOTOR RUN TIME.

3. MOTOR STARTS: THE NUMBER OF MOTOR STARTS, AS INDICATED BY PUMP PROOF, SHALL BE

TOTALIZED.

4. EMERGENCY HVAC OFF: ON ACTIVATION OF THE EMERGENCY HVAC OFF SWITCH (EHO), THE PUMP

SHALL STOP.

SAFETIES

1. COOLING TOWER VIBRATION SWITCH: UPON SENSING EXCESS VIBRATION THE COOLING TOWER FAN SHALL STOP AND AN ALARM SHALL BE INDICATED AT THE OWS. THE CHILLER STOP SEQUENCE FOR THE ASSOCIATED CHILLER SHALL BE INITIATED. THE COOLING TOWER SHALL REMAIN LOCKED OUT

FROM FURTHER OPERATION UNTIL THE ALARM IS MANUALLY CLEARED AT THE OWS.

2. UPON ACTUATION OF LOCAL COOLING TOWER DISCONNECT, LDL SHALL DISABLE VFD THROUGH

HARDWIRE INTERLOCK.

COMMISSIONING

1. ALL SETPOINTS, PERCENTAGES, TIME DELAYS, ETC. SHALL BE ADJUSTABLE.
