SPRAY PUMP

SEQUENCE OF OPERATION· CONDENSER WATER SYSTEM

EQUIPMENT

THE CONDENSER WATER SYSTEM, AS IT APPLIES TO THE BUILDING AUTOMATION SYSTEM (BAS), CONSISTS OF THE FOLLOWING EQUIPMENT:

CONDENSER WATER PUMPS, CWP-1 & CWP-2 COOLING TOWER, CT-1 BOILER, B-1 & BOILER PUMP, BP-1

CONDENSER WATER PUMP CONTROL SEQUENCE

CONDENSER WATER PUMPS: THE CONDENSER WATER PUMP MOTORS SHALL OPERATE AS LEAD/ LAG WITH ONLY THE LEAD PUMP OPERA TIN G. THE LAG PUMP SHALL BE DESIGNATED AS THE STAND-BY PUMP. THE BAS SHALL START THE LEAD CONDENSER WATER PUMP WHEN THE BUILDING IS IN NEED OF COOLING OR HEATING. THE CONDENSER WATER PUMPS HAVE VFDS. WHEN ANY CONDENSER WATER PUMP MOTOR IS STARTED, THE BAS SHALL START THE PUMP AT 25 PERCENT SPEED. WHEN THE STATUS OF THE PUMP MOTOR IS PROVEN VIA A CURRENT SWITCH INPUT TO THE BAS, THE BAS SHALL GRADUALLY INCREASE ITS SPEED BASED UPON DIFFERENTIAL PRESSURE CONTROL CRITERIA. IF THE CONDENSER WATER PUMP MOTOR DOES NOT PROVE STARTED WITHIN 5 SECS (ADJ), THE BAS SHALL CONSIDER THAT PUMP MOTOR "FAILED", GENERATE AN ALARM, AND REMOVE IT FROM ROTATION.

TO STOP A CONDENSER WATER PUMP MOTOR, THE BAS SHALL SLOWLY DECREASE THE SPEED OF THE PUMP MOTOR. THE BAS SHALL STOP THE DESIRED CONDENSER WATER PUMP WHEN IT REACHES ITS MINIMUM SPEED.

THE BAS SHALL MONITOR THE RUNTIME OF EACH CONDENSER WATER PUMP MOTOR AND DESIGNATE EACH PUMP SYSTEM AS LEAD AND LAG BASED UPON THE NEED TO EQUALIZE RUNTIME FOR EACH CONDENSER WATER PUMP MOTOR. WHEN A CONDENSER WATER PUMP IS DOWN FOR MAINTENANCE, THE BAS SHALL ALLOW THE OPERATOR TO SELECT "MAINTENANCE" AND THE BAS SHALL TAKE THIS PIECE OF EQUIPMENT OUT OF THE ROTATION.

CONDENSER WATER DIFFERENTIAL PRESSURE CONTROL: THE BAS SHALL MEASURE THE CONDENSER WATER DIFFERENTIAL PRESSURE AND MODULATE THE CONDENSER WATER PUMP VFD TO MAINTAIN DIFFERENTIAL PRESSURE SETPOINT (ADJ.), AS DETERMINED DURING TEST & BALANCE.

1 CONDENSER WATER SYSTEM CONTROL SCHEMATIC

COOLING TOWER CONTROL SEQUENCE

COOLING TOWER OPERATION:

SCALE: N.T.S.

UPON THE CALL FOR LEAD CONDENSER WATER PUMP STARTUP, THE BAS SHALL MONITOR THE CONDENSER WATER SUPPLY TEMPERATURE. WHEN THE SUPPLY WATER TEMPERATURE HAS BEEN 1°F (ADJ)ABOVE THE CONDENSER WATER SUPPLY TEMPERATURE COOLING SETPOINT FOR A PERIOD OF 600 SECONDS (ADJ), THE BAS SHALL MODULATE OPEN THE COOLING TOWER ISOLATION VALVE. AFTER THE ISOLATION VALVE IS PROVEN FULLY OPEN (OPEN TO THE TOWER) VIA POSITION INDICATION, THE BAS SHALL BEGIN THE COOLING TOWER STARTUP SEQUENCE.

UPON THE CALL FOR COOLING TOWER STARTUP, THE SPRAY PUMP SHALL START AND RUN. IF THE CONDENSER WATER SUPPLY TEMPERATURE CONTINUES TO RISE ABOVE THE COOLING SETPOINT, THE BAS SHALL START THE COOLING TOWER FAN(S). THE FAN(S) SHALL START AT 25 PERCENT SPEED OR MINIMUM SPEED TO MAINTAIN MINIMUM COOLING TOWER AIRFLOW. WHEN THE STATUS OF THE FAN MOTOR IS PROVEN VIA A VFD SPEED SIGNAL INPUT TO THE BAS, THE BAS SHALL GRADUALLY INCREASE THE FAN MOTOR AS REQUIRED TO MAINTAIN THE CONDENSER WATER SUPPLY TEMPERATURE COOLING SETPOINT. IF THE COOLING TOWER FAN MOTOR DOES NOT PROVE STARTED WITHIN 5 SECS (ADJ), THE BAS SHALL CONSIDER THE FAN MOTOR "FAILED" AND GENERATE AN ALARM.

ON A DROP IN COOLING LOAD AND THE CONDENSER WATER SUPPLY TEMPERATURE CONTINUES TO DROP BELOW THE SUPPLY TEMPERATURE COOLING SETPOINT, THE REVERSE SEQUENCE SHALL OCCUR UNTIL THE BAS CALLS FOR COOLING TOWER SHUTDOWN. ONCE THE COOLING TOWER IS DISABLED, THE BAS SHALL MODULATE THE COOLING TOWER ISOLATION VALVE CLOSED (CLOSED TO THE TOWER).

COOLING TOWER VIBRATION: THE BAS SHALL MONITOR THE VIBRATION SWITCH STATUS DURING COOLING TOWER OPERATION. IF THE STATUS CHANGES, THE COOLING TOWER SHALL SHUT DOWN AND GENERATE AN ALARM.

SYSTEM FREEZE PROTECTION

COOLING TOWER MINIMUM FLOW: WHEN NO COOLING DEMAND EXISTS AND THE OUTSIDE AIR TEMPERATURE IS EQUAL TO OR LESS THAN 40oF (ADJ), THE BAS SHALL START THE LEAD CONDENSER WATER PUMP AND MODULATE OPEN THE COOLING TOWER ISOLATION VALVE (OPEN TO THE TOWER) TO ALLOW FLOW THROUGH COOLING TOWER COIL. THE ISOLATION VALVE SHALL MODULATE TO MAINTAIN MINIMUM FLOW THROUGH THE COIL DURING FREEZE PROTECTION MODE. THE MINIMUM FLOW REQUIRED FOR FREEZE.

PROTECTION SHALL BE DETERMINED BY THE COOLING TOWER MANUFACTURER. THE CONDENSER WATER BYPASS VALVE SHALL ALSO MODULATE OPEN AS REQUIRED TO ALLOW FLOW THROUGH THE SYSTEM WHEN HEATING DEMAND IS LOW OR DURING UNOCCUPIED PERIODS.

COOLING TOWER BASIN TEMPERATURE: THE BAS SHALL MONITOR THE BASIN WATER TEMPERATURE IN THE COOLING TOWER. IF THE BASIN TEMPERATURE FALLS BELOW 45°F (ADJ), AN ALARM SHALL BE GENERATED.

CONDENSER WATER PIPE HEAT TRACING: THE CONDENSER WATER PIPING HEAT TRACING SHALL BE CONTROLLED BY A STAND-ALONE THERMOSTAT AND SHALL ACTIVATE WHEN THE OUTSIDE AIR TEMPERATURE IS EQUAL OR LESS THAN 40°F (ADJ).

CONDENSER WATER BYPASS VALVE· MIN. FLOW CONTROL

THE BAS SHALL MEASURE CONDENSER WATER FLOW THROUGH THE SYSTEM AND, AS THE CONDENSE WATER FLOW DROPS BELOW THE MINIMUM CONDENSER WATER PUMP FLOW SETPOINT, AS DETERMINED DURING TEST AND BALANCE, THE BAS SHALL MODULATE THE CONDENSER WATER BYPASS VALVE OPEN TO MAINTAIN THE MINIMUM CONDENSER WATER FLOW SETPOINT.

CONDENSER WATER TEMPERATURE CONTROL

CONDENSER WATER SUPPLY TEMPERATURE SETPOINT: THE BAS SHALL MONITOR THE CONDENSER WATER SUPPLY TEMPERATURE AND SHALL MAINTAIN THE CONDENSER WATER SUPPLY TEMPERATURE SETPOINTS AS FOLLOWS: · COOLING: THE SETPOINT SHALL BE 85°F (ADJ.). ·HEATING: THE SETPOINT SHALL BE 70°F (ADJ.).

BOILER CONTROL SEQUENCE THE BAS SHALL MONITOR AND CONTROL THE NATURAL GAS FIRED BOILER, B-1. VIA AN INTEGRATED INTERFACE WITH THE BOILER MANUFACTURER'S SUPPLIED BOILER CONTROL SYSTEM.

STARTING BOILER: THE BAS SHALL MONITOR THE CONDENSER WATER SUPPLY TEMPERATURE. WHEN THE SUPPLY WATER TEMPERATURE HAS BEEN 1oF (ADJ) BELOW THE CONDENSER WATER SUPPLY TEMPERATURE HEATING SETPOINT FOR A PERIOD OF 600 SECONDS (ADJ), THE BAS SHALL ENABLE THE BOILER. THE BOILER CONTROL SYSTEM SHALL START THE BOILER FOLLOWING THE MANUFACTURER'S START-UP SEQUENCE PROGRAMMED

DDC

INTO THE BOILER CONTROLLER, INCLUDING STARTING THE BOILER PUMP. THE BOILER PUMP SHALL BE FULLY CONTROLLED BY THE BOILER CONTROLLER. THE BAS SHALL MONITOR THE PUMP STATUS ONLY. THE BOILER SHALL RUN TO MAINTAIN THE CONDENSER WATER SUPPLY TEMPERATURE HEATING SETPOINT. STOPPING BOILER: WHEN THE SUPPLY WATER TEMPERATURE HAS BEEN 1oF (ADJ) ABOVE THE CONDENSER WATER SUPPLY TEMPERATURE HEATING SETPOINT FOR A PERIOD OF 600 SECONDS (ADJ), THE BAS SHALL DISABLE THE BOILER. THE BOILER CONTROL SYSTEM SHALL STOP THE BOILER FOLLOWING THE MANUFACTURER'S SHUT-DOWN SEQUENCE PROGRAMMED INTO THE BOILER CONTROLLER.

ALARMS AND SHUTDOWNS

ALARMS AND SHUTDOWNS:THE BOILERS SHALL SHUT DOWN AND GENERATE AN ALARM UPON RECEIVING AN EMERGENCY SIGNAL. BOILER FAILURE: COMMANDED ON, BUT THE STATUS IS OFF. BOILER GENERAL ALARM COOLING TOWER FAN FAILURE: COMMANDED ON, BUT THE STATUS IS OFF. COOLING TOWER FAN IN HAND: COMMANDED OFF, BUT THE STATUS IS ON. COOLING TOWER FAN VFD FAULT COOLING TOWER SPRAY PUMP FAILURE: COMMANDED ON, BUT THE STATUS IS OFF. COOLING TOWER SPRAY PUMP RUNNING IN HAND: COMMANDED OFF, BUT THE STATUS IS ON. HIGH CONDENSER WATER SUPPLY TEMP: IF THE CONDENSER WATER SUPPLY TEMPERATURE IS GREATER THAN 95° F (ADJ.). LOW CONDENSER WATER SUPPLY TEMP: IF THE CONDENSER WATER SUPPLY TEMPERATURE IS LESS THAN 60° F (ADJ.). CONDENSER WATER PUMP FAILURE: COMMANDED ON, BUT THE STATUS IS OFF. CONDENSER WATER PUMP RUNNING IN HAND: COMMANDED OFF, BUT THE STATUS IS ON. CONDENSER WATER PUMP RUNTIME EXCEEDED: STATUS RUNTIME EXCEEDS A USER DEFINABLE LIMIT. CONDENSER WATER PUMP VFD FAULT HIGH CONDENSER WATER DIFFERENTIAL PRESSURE: IF THE CONDENSER WATER DIFFERENTIAL PRESSURE IS 25% (ADJ.) GREATER THAN SETPOINT. LOW CONDENSER WATER DIFFERENTIAL PRESSURE: IF THE CONDENSER WATER DIFFERENTIAL PRESSURE IS 25% (ADJ.) LESS THAN SETPOINT. LOW CONDENSER WATER FLOW: IF THE CONDENSER WATER FLOW IS 25% (ADJ.) LESS THAN SETPOINT. ~ LOW COOLING TOWER LEAVING WATER TEMP: IF THE COOLING TOWER LEAVING WATER TEMPERATURE IS LESS THAN 50° F (ADJ.).
