570-16-302PHASE 2 CHILLER

INFRASTRUCTURE ON FRESNO

CAMPUS

RECORD DRAWINGS

2615 E CLINTON AVE, FRESNO, CA 93703

CHILLED WATER PLANT IS DESIGNED FOR N+1 REDUNDANCY. THE NEW CHILLERS CH-3 AND CH-4 SHALL OPERATE AS THE PRIMARY CHILLERS. THE OPERATOR SHALL SELECT THE LEAD/LAG ORDER CHILLERS IN THE SEQUENCE. (E) CH-1 AND (E) CH-2 IN BUILDING 22, ASSOCIATED PRIMARY, SECONDARY, AND CONDENSER WATER PUMPS, AND COOLING

TOWER PUMPS ALL REMAIN. THEY PROVIDE PEAK DEMAND AND BACKUP CAPACITY.

FAILURE OF A SINGLE COMPONENT WILL ONLY DISABLE THAT COMPONENT, NOT RELATED COMPONENTS.

THE PLANT IS CONTROLLED THROUGH THE ENGINEERING CONTROL CENTER (ECC).

MAJOR COMPONENTS

CHILLER WITH MOTORIZED BUTTERFLY VALVES TO SHUT OFF CHILLED WATER AND CONDENSER WATER TO CHILLER

WHEN NOT IN OPERATION ((E) CH-1, (E) CH-2, CH-3, AND CH-4).

PRIMARY CHILLED WATER PUMPS TO CIRCULATE CHILLED WATER THROUGH CHILLERS ((E)CHP-1, (E)CHP-2, (E)CHP-3, AND (E)CHP-4).

SECONDARY CHILLED WATER PUMPS TO CIRCULATE CHILLED WATER THROUGHOUT CAMPUS

((E)CHWP-1, (E)CHWP-2, AND (E)CHWP-3).

COOLING TOWERS TO REJECT CHILLER HEAT TO THE ENVIRONMENT, WITH MOTORIZED BUTTERFLY

VALVES TO SHUT OFF CONDENSER WATER FLOW TO TOWER WHEN NOT IN OPERATION.

CONDENSER WATER PUMPS TO CIRCULATE CONDENSER WATER FROM THE CHILLER TO THE COOLING

TOWER ((E)CWP-1, (E)CWP-2, (E)CWP-3, AND (E)CWP-4).

CHILLER STAGING SEQUENCE

ON SIGNAL FROM THE ECC, THE FIRST SECONDARY CHILLED WATER PUMP IS ENABLED. VARIABLE FREQUENCY DRIVE BRINGS PUMP UP TO SPEED THROUGH INTERNAL RAMP-UP RATE (180 SECONDS, ADJUSTABLE). PUMP IS SET TO MAINTAIN A DIFFERENTIAL SETPOINT BETWEEN SUPPLY AND RETURN HEADERS (REFER TO CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE SETPOINT SEQUENCE). IF FIRST PUMP IS UNABLE TO MAINTAIN PRESSURE DIFFERENTIAL, A SECOND PUMP IS STARTED AND RAMPED UP TO SAME SPEED AS OPERATING PUMP. ONCE EQUAL SPEED IS ACHIEVED, BOTH PUMPS SLOW DOWN TOGETHER TO MAINTAIN PRESSURE. WHEN PUMPS SLOW TO 60% SPEED, LEAD PUMP CYCLES OFF AND LAG PUMP BECOMES LEAD PUMP. ON NEXT PUMP CYCLE, SPARE PUMP BECOMES LAG PUMP.

ON FAILURE OF A PUMP AS REPORTED BY VFD, PUMP IS LOCKED OUT AND TAKEN OUT OF THE ROTATION. ALARM IS

REPORTED BY ECC.

FLOW METER ON CHILLED WATER MAIN HEADER PROVIDES DATA TO THE ECC TO DETERMINE THE TOTAL CHILLED WATER BEING SUPPLIED TO THE CAMPUS. PROVIDE TEMPERATURE SENSORS ON MAIN SUPPLY AND MAIN RETURN HEADERS. ECC CALCULATES THE TONNAGE BEING USED BY THE CAMPUS AND DETERMINES WHEN TO ADD OR

REMOVE CHILLERS.

ON RISE IN CHILLED WATER SUPPLY HEADER ABOVE 45°F (ADJUSTABLE), ECC COMMANDS MOTORIZED BUTTERFLY VALVES ON FIRST CHILLER (CH-3 OR CH-4) CHILLED WATER CIRCUIT AND CONDENSER WATER CIRCUIT TO OPEN. THE VALVE TIMING SHALL BE ADJUSTABLE THROUGH THE ECC SO THAT THE VALVES OPEN SLOW ENOUGH TO PREVENT TRIPS ON LOW FLOW FOR THE OPERATING CHILLERS. AFTER PROOF OF FLOW IS RECEIVED, ECC COMMANDS ON FIRST PRIMARY CHILLED WATER PUMP AND FIRST CONDENSER WATER PUMP. FIRST COOLING TOWER ISOLATION BUTTERFLY VALVE IS OPENED. COOLING TOWER BYPASS VALVE OPERATES AS REQUIRED TO PROVIDE CONDENSER WATER RETURN TEMPERATURE OF 75°F (ADJUSTABLE) TO CHILLER. AFTER 30 SECONDS (ADJUSTABLE) CHILLER IS ENABLED. IF CHILLER SENSES PROPER CHILLED WATER AND CONDENSER WATER FLOW, CHILLER OPERATES THROUGH ITS INTERNALLY SUPERVISED SEQUENCE TO CONTROL DISCHARGE WATER TEMPERATURE TO 45 °F. VFD INTERNAL TO CHILLER ADJUSTS CHILLER SPEED TO ADJUSTS CHILLER SPEED TO ADJUST CHILLER CAPACITY.

COOLING TOWER BYPASS VALVE CLOSES WHEN RETURN WATER REACHES 75°F (ADJUSTABLE). COOLING TOWER INTERNAL CONTROLS AND VFD ADJUST FAN SPEED TO MAINTAIN BASIN TEMPERATURE OF 85°F (ADJUSTABLE). IF COOLING TOWER IS OFF AND BASIN TEMPERATURE DROPS BELOW 35°F (ADJUSTABLE), ELECTRIC IMMERSION HEATER

IS ENERGIZED.

CH-3 AND CH-4 SEQUENCE OF OPERATION

ECC MONITORS CHILLER OUTPUT AND IF TONNAGE OF THE CHILLER IS AT 80% FOR 20 MINUTES AND

DOES NOT SATISFY CAMPUS LOAD, SECOND CHILLED WATER PRIMARY PUMP IS STARTED AND

AFTER PROOF OF OPERATION BY CURRENT SENSOR, SECOND CHILLER (CH-3 OR CH-4) CHILLED WATER ISOLATION BUTTERFLY VALVES ARE OPENED. SECOND CONDENSER WATER PUMP IS STARTED, AND AFTER PROOF OF OPERATION BY CURRENT SENSOR, SECOND CHILLER CONDENSER WATER ISOLATION BUTTERFLY VALVES ARE OPENED. SECOND COOLING TOWER ISOLATION BUTTERFLY VALVE IS ALSO OPENED. AFTER PROOF OF VALVES OPENING, CHILLER IS ENABLED. IF CHILLER SENSES PROPER CHILLED WATER AND CONDENSER WATER FLOW, CHILLER OPERATES THROUGH ITS INTERNALLY SUPERVISED SEQUENCE TO CONTROL DISCHARGE WATER TEMPERATURE TO 45°F. ON FAILURE OF ANY COMPONENT TO OPERATE PROPERLY ON START UP, THE COMPONENT SHALL BE DISABLED AND NEXT AVAILABLE COMPONENT (PUMP, CHILLER, OR TOWER) IS BROUGHT INTO SERVICE TO ALLOW START SEQUENCE TO PROCEED. FAILED COMPONENTS ARE LOCKED-OUT AND ECC GENERATES ALARM. ON INCREASE IN LOAD BEYOND CHILLER 3 AND CHILLER 4 CAPACITY AT 80%, THIRD CHILLER GROUP (CH-1

OR CH-2) IS BROUGHT ON PER SEQUENCE.

ON DROP IN LOAD BELOW 40% OF THE 3 CHILLERS, THE THIRD CHILLER (CH-1 OR CH-2) IS COMMANDED OFF. AFTER SHUTDOWN SEQUENCE BY CHILLER IS COMPLETE, THE ASSOCIATED CHILLED WATER AND CONDENSER WATER MOTORIZED VALVES CLOSE, TOWER MOTORIZED VALVE SHUTS, AND ASSOCIATED CHILLED WATER AND CONDENSER WATER PUMPS SHUT OFF AFTER PROOF OF VALVE CLOSURE. FAILURE OF ANY COMPONENT TO PROPERLY CLOSE OR SHUT OFF ALARMS AT ECC. ON DROP IN LOAD BELOW 30% OF THE TWO CHILLER CAPACITY, SECOND CHILLER (CH-3 OR CH-4) IS COMMANDED OFF PER THE SEQUENCE ABOVE.

ROTATE ALL COMPONENTS TO BE BROUGHT ONLINE AS LOADS INCREASE.

REFRIGERANT ALARM:

REFRIGERANT ALARM SYSTEM MONITORS CHILLER ROOM. ON DETECTION OF REFRIGERANT IN THE ROOM, ECC IS NOTIFIED. ON RISE IN CONCENTRATION ABOVE 25,000 PPM, ALARM AT BUILDING IS TRIGGERED, EMERGENCY PURGE FAN IS STARTED, AND MOTORIZED OUTDOOR AIR LOUVERS ARE OPENED. CHILLERS ARE COMMANDED OFF THROUGH THE ECC, AND AFTER CHILLERS ARE SHUT DOWN THROUGH THEIR INTERNAL SEQUENCE, ALL CONDENSER AND CHILLED WATER PUMPS SHUT DOWN, AND MOTORIZED VALVES CLOSE.

CONDENSER WATER PUMP SPEED CONTROL

THE ECC SHALL MODULATE THE SPEED OF THE OPERATING PUMPS TOGETHER TO MAINTAIN THE CONDENSER WATER HEADER DIFFERENTIAL PRESSURE AT SETPOINT ANYTIME ANY OF THE PUMPS ARE OPERATING. THE DIFFERENTIAL PRESSURE SETPOINT SHALL BE ESTABLISHED BY THE TEST AND BALANCE CONTRACTOR TO MEET THE REQUIRED CONDENSER WATER FLOWRATE FOR

EACH CHILLER.

PRIMARY CHILLED WATER PUMP

WHEN CH-4 IS STARTED THE ONLY PUMP THAT SHALL BE OPERATED WITH IT IS CHP-4. WHEN RUNNING WITH CH-4, PRIMARY

CHILLED WATER PUMP CHP-4, THE ECC SHALL COMMAND THE CHP-4 TO RUN.

CHILLED WATER SYSTEM DIFFERENTIAL PRESSURE SETPOINT

THE ECC SHALL RESET THE SYSTEM DIFFERENTIAL PRESSURE SETPOINT FOR EACH OF THE FIVE DIFFERENTAIL PRESSURE SENSORS USING A TRIM AND RESPOND LOGIC WITHIN THE RANGE OF 5 PSIG TO 20 PSIG ONCE THE MAXIMUM CHILLED WATER TEMPERATURE SETPOINT IS REACHED. ONCE THE TEMPERATURE SETPOINT IS REACHED, THE DIFFERENTIAL PRESSURE SETPOINT FOR EACH OF THE FIVE ZONES SHALL BE RESET BASED ON THE VALVE POSITIONS IN EACH ZONE. EACH DIFFERENTAIL PRESSURE SETPOINT SHALL BE TRIMMED BY 0.1 PSIG EVERY TWO MINUTES UNTIL A VALVE IN EACH DIFFERENTIAL PRESSURE ZONE IS 50% OPEN. WHEN A VALVE IN THE ZONE RISES TO 80% OPEN, THE DIFFERENTIAL PRESSURE SETPOINT SHALL BE INCREASED BY 0.1 PSIG EVERY TWO MINUTES. ALL SETPOINTS SHALL BE ADJUSTABLE THROUGH THE OPERATOR WORKSTATION FOR EACH DIFFERENTIAL PRESSURE SENSOR. THE PUMPS SHALL BE CONTROLLED TO THE DIFFERENTIAL PRESSURE SENSOR

WHICH IS FURTHEST BELOW SETPOINT.

IN ADDITION TO THE HARDWIRED POINTS SHWON, THE CHILLERS

SHALL BE CONNECTED TO THE ECC THROUGH A

BACNET NETWORK CONNECTION. THE FOLLOWING POINTS

SHALL BE MONITORED OR CONTROLLED BY THE FMS:

A. LEAVING CHILLED WATER TEMPERATURE

B. ENTERING CHILLED WATER TEMPERATURE
