THE GLYCOL PIPING MAIN DOWNSTREAM OF THE CHILLED WATER/GLYCOL HEAT EXCHANGER SHALL BE MODIFIED TO INSTALL THE TEMPORARY DRY COOLER CONNECTIONS WITH PHASING VALVES AND A NEW MAIN SHUTOFF VALVE TO ALLOW THE PLANT TO BE ISOLATED WITH THE SYSTEM STILL IN OPERATION WITH THE 1200 MBH TEMPORARY DRY COOLER.

INSTALL THE NEW MINIMUM FLOW BYPASS VALVE AT THE TOP OF THE RISER ON LEVEL 6 AND ASSOCIATED CONTROLS FOR THE

BYPASS VALVE (INCLUDING RELOCATION OF THE EXISTING D/P SENSOR).

PROVIDE PIPING FOR THE TEMPORARY DRY COOLER. NEW 4” BLACK STEEL LINES SHALL BE INSTALLED FROM THE TIE-IN POINT TO THE RISER/MAIN TO THE EXTERIOR WALL SPACE BELOW THE ROLL-UP DOOR. PROVIDE INSULATED PLYWOOD BLANK-OFF AROUND THE PIPING AND BELOW THE OPEN PORTION OF THE DOOR. PROVIDE A MEANS OF LOCKING THE ROLL-UP DOOR FOR SECURITY. THE TEMPORARY DRY COOLER SHALL BE LOCATED ON GRADE OUTSIDE THE ROLL-UP DOOR. TEMPORARY PIPING SHALL BE EXTENDED FROM THE VICINITY OF THE DOOR TO THE DRY COOLER. FROM THIS POINT THE MFR MAY USE STANDARD PIPING MATERIAL FOR CONNECTION. THE INTENT IS FOR THE PIPING TO RUN ALONG THE GROUND WITH PLYWOOD COVERS OVER THE PIPING TO PROTECT THE PIPING FROM DAMAGE. THE PIPING AND DRY COOLER SHALL BE LOCATED IN SUCH A WAY TO NOT BLOCK FACILITY ACCESS AND OPERATION (COORDINATE FINAL LOCATION WITH OWNER). FILL TEMPORARY PIPING AND DRY COOLER WITH A 40% PROPYLENE

GLYCOL SOLUTION.

UTILIZE THE EXISTING SHUTOFF VALVES IN THE DRY COOLER PIPING WHERE IT FIRST ENTERS THE BUILDING TO ISOLATE THE MAINS

TO THE EXISTING DRY COOLERS. DRAIN THE EXISTING PIPING BACK TO THE DRY COOLERS.

SHUT DOWN THE EXISTING DRY COOLERS AND RUN OFF OF THE HEAT EXCHANGER/TEMPORARY DRY COOLER FOR N+1 REDUNDANCY.

PROCEED WITH INSTALLING THE NEW DRY COOLERS AND REMAINING SCOPE OF WORK INDICATED.

WHEN INSTALLATION IS COMPLETE, TRANSFER THE LOAD OFF OF THE TEMPORARY DRY COOLER AND BACK TO THE NEW DRY COOLER SYSTEM. ONCE THE NEW PLANT OPERATION IS CONFIRMED, REMOVE THE TEMPORARY DRY COOLER AND ALL OF THE

TEMPORARY PIPING/ELECTRICAL ETC.

THE GLYCOL SYSTEM IS A CRITICAL SYSTEM AND CANNOT BE SHUT DOWN.

THE PROJECT SHALL END WITH THE GLYCOL SYSTEM RETURNING TO THE NEW DRY COOLERS PROVIDING HEAT REJECTION WITH

CHILLED WATER HX BACKUP.

EXISTING GLYCOL PUMPS

AT ALL TIMES A MINIMUM OF 1 PUMP SHALL RUN.

THE CHILLED WATER PUMP SPEED SHALL BE VARIED FROM THE MIN SPEED (20 HZ) TO THE MAX SPEED

(60 HZ) TO MAINTAIN THE D/P SET POINT.

THE PUMPS SHALL BE IN A 1 DUTY CONFIGURATION WITH A BACK-UP. THE PUMPS SHALL BE STAGED TO EQUALIZE RUN TIME. THE PUMP COMING ON SHALL START AND RUN TO 20HZ PRIOR TO THE OLD DUTY PUMP SHUTTING OFF SO THAT THE MIN D/P IS MAINTAINED AT ALL TIME. THE PUMP ROTATION SHOULD

BE DONE ONE A MONTH ON A WEEKDAY AT 7AM.

IF THE DUTY PUMP WOULD FAIL, THE DUTY PUMP SHALL BE TAKEN OUT OF ROTATION AND THE PUMP THAT WAS THE STANDBY PUMP SHALL NOW BE THE DUTY PUMP. WHEN THE FAILED PUMP IS REPAIRED AND THE ALARM CLEARED, THE FORMERLY FAILED PUMP SHALL REMAIN OFF UNTIL AT LEAST THE NEXT

TIME TO ROTATE PUMPS.

EXISTING MODE SWITCHING - DRY COOLER / FREE COOLING HX

THERE SHALL BE A MODE SELECTOR TO DETERMINE ON THE GRAPHICS.

THERE ARE (2) 2-WAY VALVES TO DETERMINE THE DIRECTION OF FLOW. NORMALLY THE

FLOW WILL GO TO THE DRY COOLERS. THIS SHALL BE THE DEFAULT MODE. THE OTHER

MODE IS CHILLED WATER BACKUP. IN THIS MODE THE CHILLED WATER GOES TO THE HX.

WHEN SWITCHING BETWEEN MODES, THE ISOLATION VALVE THAT IS CLOSED SHALL FULLY

OPEN BEFORE THE OPEN VALVE BEGINS TO CLOSE. AT ALL TIMES THERE SHALL BE A

MINIMUM OF 1 FULLY OPEN VALVE.

IF THE TEMPERATURE COMING FROM THE DRY COOLERS IS NOT AT SET POINT FOR A

PERIOD OF 15 MINUTES, AN ALARM SHALL BE GENERATED. IF THE TEMPERATURE EXCEEDS

THE HIGH LIMIT BY MORE THAN 5 DEGREES AT ANY TIME THERE SHALL BE AN ALARM AND

THE MODE SHALL BE SWITCHED TO CHILLED WATER MODE.

IN CHILLED WATER MODE, THE HX SHALL BE THE PRIORITY. NON CRITICAL AHU LOADS

SHALL BE SHED TEMPORARILY AS REQUIRED TO MAINTAIN SET POINT USING THE HX. THE

AHUS ON LV 3 SHOULD BE SHED FIRST (TOGGLES TO CHANGE THE LEVEL OF AHUS TO BE

SHUT OFF FROM CHILLED WATER).

TEMPERATURE CONTROL

IN DRY COOLER MODE, THE DRY COOLERS SHALL BE CONTROLLED (FAN STAGING) TO

MAINTAIN THE TEMPERATURE SET POINT 108oF (ADJ). THE DESIGN INTENT IS ONE DRY

COOLER WILL SATISFY THE BUILDING LOAD REQUIREMENTS UNDER NORMAL CONDITIONS.

IF THE GLYCOL LOOP SUPPLY TEMPERATURE RISES ABOVE 110oF (ADJ), THE LAG DRY

COOLER SHALL BE ENERGIZED AND THE ASSOCIATED ISOLATION VALVE MODULATED

OPEN TO MAINTAIN LOOP SUPPLY TEMPERATURE SET POINT. WHEN THE LOOP SUPPLY

TEMPERATURE DROPS BELOW 108oF (ADJ), THE LAG DRY COOLER SHALL BE DE-

ENERGIZED AND THE ASSOCIATED ISOLATION VALVE CLOSED.

IN HX MODE, THE CHILLED WATER CONTROL VALVE SHALL MODULATE TO MAINTAIN THE

TEMPERATURE SET POINT AT THE TEMPERATURE SENSOR LEAVING THE HX. WHEN NOT IN

HX MODE, ONCE A MONTH THE CONTROL VALVE ON THE CHILLED WATER LINE SHALL

MODULE SLOWING FROM 0% OPEN TO 100% OPEN AND THEN BACK TO 0% OPEN. THE

CHILLER STAGING / PUMP STATING SHALL BE LOCKED OFF AT THIS TIME TO PREVENT ANY

ADDITIONAL CHILLERS OR PUMPS TO TURN ON DURING THIS SHORT FLOW INCREASE. THIS

SHOULD BE DONE AT 1AM ON A WEEKDAY.

DRY COOLER STAGING

THE BAS SHALL ENABLE THE DRY COOLERS WHEN THE PLANT IS ENABLED. THE DRY COOLER

CONTROLLER SHALL OPERATE TO MAINTAIN THE SUPPLY CHILLED WATER WITH GLYCOL

TEMPERATURE SET POINT.

THE BAS SHALL ISOLATE A DRY COOLER WHEN THE DRY COOLER IS NOT RUNNING. AT A MINIMUM, ONE ISOLATION VALVE SHALL ALWAYS BE OPEN. THE VALVES ARE SHOWN AS MODULATING VALVES

SO THE TRANSITION CAN SLOW ENOUGH TO ALLOW TIME FOR THE SYSTEM TO REACT. THE

MINIMUM FLOW IN THE SYSTEM SHOULD BE RESET PRIOR TO TURNING ON A SECOND DRY COOLER

SO THAT THE FLOW STAYS ABOVE THE MINIMUM FLOW DURING THE TRANSITION.

DRY COOLER STAGING SHALL BE USED TO EQUALIZE DRY COOLER RUN TIME. THE LEAD DRY

COOLER SHALL ROTATE AT 6AM IN THE MORNING ON A WEEKDAY TO ROTATE THE DRY COOLER

POSITION. THE DRY COOLER WITH THE SHORTEST RUN TIME SHALL BE THE LEAD.

BYPASS CONTROL

THE BYPASS VALVE SHALL BE USED AS PART OF THE D/P CONTROL. WHEN THE PUMPS

REACH MIN SPEED, THE BYPASS VALVE SHALL MODULATE TO MAINTAIN THE D/P SET POINT.
