A. CHILLED WATER SYSTEM WILL CONSIST OF ONE AIR-COOLED, CHILLER

AND DUAL PUMP PACKAGED PUMPING SYSTEM.

6. NORMAL OPERATION' MODES:

A. NORMAL DAMPER D-6 POSITIONING, WITH MINIMUM OUTSIDE AIR. WHEN THE AIR SYSTEM IS OPERATING WITH THE 'OUTSIDE AIR

ECONOMIZER' MODE DISABLED, THE SYSTEM SHALL OPERATE WITH THE REQUIRED MINIMUM VENTILATION (OUTSIDE) AIR, AND

THE SYSTEM DAMPERS SHALL BE POSITIONED AS FOLLOWS:

(1) THE OUTSIDE AIR DAMPER D-6 BE OPENED TO ITS MINIMUM OUTSIDE AIR POSITION. THE POSITION SHALL BE DETERMINED

BY THE TEST AND BALANCE CONTRACTOR.

(2) D-4 RETURN AIR DAMPER AS WELL AS SUPPLY AIR DAMPER D-7 SHALL BE IN THEIR FULL-OPEN POSITIONS.

(3) THE EXHAUST AIR DAMPERS D-1 AND D-5 SHALL BE OPEN TO OPERATE IN NORMAL VENTILATION POSITIONS (NOT ECONOMIZER).

B. OUTSIDE AIR ECONOMIZER' COOLING MODE OPERATIONS:

(1) TEMPERATURE AND HUMIDITY SENSORS SHALL BE INSTALLED IN THE OUTSIDE AIR STREAM AND IN THE RETURN AIR DUCT OF

THIS RTU. THE DDC SYSTEM SHALL USE THESE SENSORS TO CALCULATE THE ENTHALPIES OF THE RESPECTIVE

AIRSTREAMS.

(2) COMPARATIVE ENTHALPY SHALL BE USED TO AS THE BASIS FOR SWITCHING THE SYSTEM TO OPERATE IN THE 'OUTSIDE AIR

ECONOMIZER' MODE.' WHEN THE CALCULATED ENTHALPY IN THE OUTSIDE AIR IS LESS THAN THE CALCULATED ENTHALPY IN THE

RETURN AIR STREAM, THE `OUTSIDE AIR ECONOMIZER' MODE SHALL BE ENABLED.

(3) DURING THE 'OUTSIDE AIR ECONOMIZER' MODE THE OUTSIDE AIR AND BOTH EXHAUST AIR DAMPERS D-1 AND D-5 SHALL BE

MODULATED AND CONTROLLED BY THE RTU DISCHARGE AIR TEMPERATURE SENSOR THROUGH

THE DDC SYSTEM. RETURN AIR DAMPERS D-2 AND D-4 SHALL MODULATE OPEN .

(4) THE ECONOMIZER DAMPERS SHALL HAVE THE FOLLOWING OPERATION POSITIONING: OUTSIDE AIR DAMPER D-6

SHALL BE NORMALLY-CLOSED AND EXHAUST DAMPERS D-1 AND D-5 OPEN.

(5) DURING THE 'OUTSIDE AIR ECONOMIZER' MODE A SENSOR IN THE MIXED AIR PLENUM SHALL ACT, THROUGH THE DDC SYSTEM, AS A MODULATING LOW LIMIT (SET AT 50 DEGREES, F.) TO KEEP THE MIXED AIR TEMPERATURE FROM FALLING TOO LOW.

(6) THE 'OUTSIDE AIR ECONOMIZER' MODE SHALL CONTINUE UNTIL THE UNIT IS SHUTDOWN BY THE DDC SYSTEM, OR UNTIL THE

ENTHALPY IN THE OUTSIDE AIR IS HIGHER THAN THE ENTHALPY IN THE RETURN AIR STREAM. WHEN THE 'OUTSIDE AIR

ECONOMIZER' MODE IS DISABLED, THE OUTSIDE AIR DAMPER D-6 AND EXHAUST DAMPERS D-1 AND D-5 SHALL BE

RETURNED TO THEIR NORMAL VENTILATION POSITIONS.

C. SUPPLY AIR TEMPERATURE CONTROLS:

(1) THE RTU DISCHARGE AIR TEMPERATURE CONTROLLER SHALL CONTROL THE OPERATIONS OF THE

RTU DAMPERS (WHEN THE OUTSIDE AIR ECONOMIZER' MODE IS ENABLED, AS PREVIOUSLY DESCRIBED), THE CHILLED WATER

COOLING COIL AND THE ELECTRIC HEAT. UPON A RISE IN DISCHARGE AIR TEMPERATURE ABOVE THE SETPOINT 55°F, THE DDC SYSTEM

SHALL ACT TO MODULATE RTU DAMPERS AS DESCRIBED ABOVE TO PROVIDE

COOLER AIR TO REDUCE THE DISCHARGE AIR TEMPERATURE. UPON A FALL IN DISCHARGE AIR TEMPERATURE BELOW THE

SETPOINT, THE SYSTEM'S DDC SHALL ACT TO MODULATE THE DAMPERS TO INCREASE THE DISCHARGE AIR TEMPERATURE.

THE HEATING AIR COIL CONTROLLER SHALL BE MODULATD FROM DISCHARGE AIR T-RA SENSOR THROUGH RTU DDC CONTROLS.

DISCHARGE SENSOR SHALL ACT AS A MODULATING LOW LIMIT SWITCH SUCH THAT THE HEAT COILS DISCHARGE AIR SHALL BE MAINTAINED AT 50°F MINIMUM DURING HEATING OPERATIONS. SET POINT SHALL BE ADJUSTABLE

(2) WHEN THE OUTSIDE AIR TEMPERATURE IS ABOVE 50 DEGREES, F., THE HEATING SHUTOFF.

(3) COOLING COIL OPERATION SHALL BE CONTROLLED WITH A 3-WAY CONTROL VALVE. 42 DEGREES F COOLED

CHILLED WATER SHALL BE PROVIDED BY A REMOTE AIR-COOLED CHILLER, USING DUAL PUMP PUMPING

PACKAGE SYSTEM.

(4) WHEN THE DISCHARGE AIR TEMPERATURE SENSOR, THRU THE DDC, IS CALLING FOR COOLING, AND THE `OUTSIDE AIR

ECONOMIZER' MODE IS DISABLED, THE DDC SYSTEM SHALL SEND A SIGNAL TO START THE PRIMARY CHILLED WATER PUMP AND

THE CHILLER. THE DDC WILL ALSO MODULATE THE 3-WAY CONTROL VALVE TO SEND CHILLED WATER FLOW

THROUGH THE COOLING COIL.

(5) WHEN THE DISCHARGE AIR TEMPERATURE FALLS, THE DDC SYSTEM SHALL ACT TO MODULATE THE 3-WAY CONTROL VALVE TO

REDUCE THE FLOW OF CHILLED WATER THROUGH THE COOLING COIL.

(6) WHEN THE OUTSIDE AIR TEMPERATURE IS BELOW 40 DEGREES, F., ADJUSTABLE, THE CHILLER AND PUMPS SHALL BE DISABLED.

THE POSITION SHALL BE DETERMINED BY THE TEST AND BALANCE CONTRACTOR.

(4) D-2 DAMPER SHALL BE IN CLOSED POSITION.

THE DYNAMIC DUCT STATIC PRESSURE CONTROL SETPOINT SHALL BE CONTINUOUSLY MONITORED AND THE SETPOINT SHALL

BE ADJUSTED TO KEEP AT LEAST ONE AIR TERMINAL UNIT VAV BOX DAMPER AT 95 PERCENT OPEN, MINIMUM.

THE AIRFLOW THROUGH THE SUPPLY AIR FANS SHALL BE CONTINUOUSLY READ AND SENT TO THE DDC SYSTEM AND

OPERATOR'S WORKSTATION. AIRFLOW THROUGH THE EXHAUST AIR FANS SHALL BE CONTINUOUSLY READ AND

SENT TO THE DDC SYSTEM AND THE OPERATOR'S WORKSTATION.

DETECTS SMOKE. UNIT SHALL RESTART WHEN THE ALARM CLEARS.

(8) PUMPS SHALL BE ALTERNATED TO EQUALIZE EQUIPMENT RUNTIME. SELECTION OF THE LEAD AND SECOND

PUMP IS EVALUATED ON A WEEKLY BASIS. THE PUMP WITH THE LEAST RUNTIME IS THE LEAD. THE

REMAINING PUMP IS LAG. IN THE EVENT THAT THE LEAD PUMP FAILS (AS DETECTED BY A CURRENT

TRANSDUCER) THE LAG PUMP SHALL START AND AN ALARM SHALL BE ROUTED TO THE OPERATORS

8. AIR FILTERS

1. A DIFFERENTIAL PRESSURE SWITCH SHALL MONITOR STATIC PRESSURE ON THE ENTERING

AND LEAVING SIDE OF AIR FILTER BANKS. THE SET -POINT VALUE SHALL BE CONNECTED TO

TO UNIT DDC CONTROLLER AND ENABLE AN ALARM AT THE COMPUTER CONSOLE WHEN FILTERS

NEEDS TO BE REPLACED ACCORDING TO MANUFACTURERS RECOMMENDATIONS.

A. WHEN AVERAGE SPACE TEMPERATURE FALLS BELOW UNOCCUPIED HEATING SETPOINT OF 60 DEG. F (ADJ.) THE SUPPLY FAN WILL START, EXHAUST FAN WILL BE OFF. THE OUTSIDE AIR DAMPER D-6 REMAIN CLOSED AND HEATING COIL CONTROL VALVE WILL MODULATE

B. WHEN AVERAGE SPACE TEMPERATURE RISES ABOVE UNOCCUPIED COOLING SETPOINT OF 85 DEG. F (ADJ.) THE SUPPLY FAN WILL START THE OUTSIDE AIR DAMPER D-6 WILL REMAIN CLOSED. EXHAUST FAN WILL BE OFF AND HEATING COIL VALVE WILL BE CLOSED.

9. UNOCCUPIED MODE

TO HOLD A SET POINT (ADJ.) ALL R.A. DAMPERS SHALL BE OPEN. HEAT EXCHANGER SHALL BE DE-ENERGIZED.

COOLING COIL CONTROL VALVE WILL MODULATE TO HOLD A SET POINT OF 85 DEG. F (ADJ.). ALL R.A. DAMPERS SHALL BE OPEN. ENERGY

WHEEL SHALL BE DE-ENERGIZED.
