PROJECT SUMMARY

THIS PROJECT WILL REPLACE THE EXISTING HVAC SYSTEMS SERVING ANIMAL ROOMS 6 AND 7. THESE ROOMS ARE CLASSIFIED AS BSL-2 OR LOWER. SYSTEM REPLACEMENT IS NECESSITATED BY THE POOR CONDITION OF THE EXISTING FAN COIL UNITS AND OUTSIDE AIR DUCTING. SYSTEM CONDITION PROBLEMS INCLUDE CORROSION AND UNRELIABLE OPERATION. THE PROJECT WILL ALSO PROVIDE NEW HVAC SYSTEM CONTROLS THAT WILL IMPROVE THE OPERATOR-TO-SYSTEM INTERFACE AND SYSTEM CONTROLLABILITY. THE NEW SYSTEM CONTROLS WILL MAINTAIN THE ANIMAL ROOMS AT A NEGATIVE PRESSURE RELATIVE TO THE REST OF THE BUILDING.

APPLICABLE CODES AND STANDARDS

2018 INTERNATIONAL MECHANICAL CODE

2020 NATIONAL ELECTRIC CODE (NFPA 70)

MANUAL 242.1 ARS FACILITIES DESIGN STANDARDS

DESIGN CRITERIA

1. INSIDE DESIGN CONDITIONS: SEE DESIGN CONDITION SCHEDULE.

2. OUTSIDE DESIGN CONDITIONS: SEE DESIGN CONDITION SCHEDULE.

3. DESIGN COOLING LOAD

· ANIMAL ROOM 6: 15,000 BTU/HR (SENSIBLE). THIS SENSIBLE LOAD INCLUDES ~4,000 BTU/HR OF LAB EQUIPMENT HEAT REJECTION BASED ON THE FOLLOWING

ANALYSIS AND ASSUMPTIONS:

· AIR SCIENCE DOWNFLOW HOOD, MODEL DWS 36, 120V/10A. HEAT REJECTION INTO ROOM ASSUMES 75% OF RATED POWER, WITH A USE FACTOR OF 25%. TOTAL

HEAT REJECTION = 768 BTU/HR.

· THERMOSCIENTIFIC BIOSAFETY CABINET, 1300 SERIES A2, 120V/8A. HEAT REJECTION INTO ROOM ASSUMES 75% OF RATED POWER, WITH A USE FACTOR OF 25%.

TOTAL HEAT REJECTION = 614 BTU/HR.

· THERMOSCIENTIFIC LOW TEMPERATURE FREEZER, MODEL UXF30086A, 115V/16. HEAT REJECTION INTO ROOM IS BASED ON THE RATED POWER INPUT, WITH A USAGE FACTOR OF 0.41 PER ASHRAE FUNDAMENTALS CHAPTER 18 TABLE 5A. TOTAL HEAT REJECTION = 2,575 BTU/HR.

· CONCLUSION: THE 15,000 BTU/HR SENSIBLE COOLING LOAD IN ANIMAL ROOM 6 IS CONSISTENT WITH THE ESTIMATED COOLING CAPACITY OF A 3-TON COOLING SYSTEM. THE EXISTING COOLING SYSTEM HAS A 3-TON NOMINAL CAPACITY AND HAS A HISTORY OF SUCCESSFULLY MEETING THE COOLING NEEDS OF THE

ROOM (ASIDE FROM UNRELIABILITY DUE TO AGE).

· ANIMAL ROOM 7: 10,770 BTU/HR (SENSIBLE): THIS ROOM DOES NOT CURRENTLY HAVE LAB EQUIPMENT.

4. PARTICULATE FILTRATION: NEW EQUIPMENT WILL BE PROVIDED WITH NOMINAL 30% / MERV 8 FILTERS FOR PARTICULATE FILTRATION. A SECOND RACK WILL BE

SPECIFIED FOR A MERV 13 FINAL FILTER DOWNSTREAM OF THE MERV 8 FILTER THAT CAN BE ADDED IF DESIRED BY THE FIELD STATION MANAGER.

5. VENTILATION: 100% OUTSIDE AIR WILL BE PROVIDED TO ANIMAL ROOMS 6 AND 7. PER MANUAL 242.1 PARAGRAPH 9.5.3.A, THE DESIGN AIR FLOW RATE IS 15 AIR

CHANGES PER HOUR, WITH TURNDOWN TO 10-12 AIR CHANGES PER HOUR PERMISSIBLE DURING NORMAL OPERATION WHEN ROOMS ARE OCCUPIED BY ANIMALS. AIR FLOW RATES CAN BE REDUCED TO 50% OF THE DESIGN AIR FLOW RATE WHEN NO ANIMALS ARE PRESENT, BY MANUALLY CHANGING THE AIR FLOW RATE AT THE

TOUCHSCREEN IN EACH ROOM.

6. ROOM PRESSURE REQUIREMENTS: PER MANUAL 242.1 PARAGRAPH 9.5.3.A, ANIMAL ROOMS SHOULD BE MAINTAINED AT A NEGATIVE PRESSURE OF ~0.05” W.G.

RELATIVE TO ADJACENT CONNECTED SPACES. IT SHOULD BE NOTED THAT THIS LEVEL OF NEGATIVE PRESSURE MAY BE IMPOSSIBLE TO ACHIEVE GIVEN THE EXISTING BUILDING ENVELOPE AND INTERIOR WALL CONSTRUCTION. A NEGATIVE PRESSURE OF ~0.01”-0.02” W.G. MAY BE MORE REALISTIC. ROOM NEGATIVE PRESSURE WILL BE CONTROLLED BY MEASURING SUPPLY AND EXHAUST AIR FLOW RATES AND CONTROLLING THE SUPPLY FAN TO ALWAYS MAINTAIN A LOWER CFM THAN THE EXHAUST

FAN.

EXISTING SYSTEM DESCRIPTION

THE EXISTING HVAC SYSTEM SERVING ANIMAL ROOM 7 INCLUDES FAN COIL FC-1, EXHAUST FAN EF-1, AND CONDENSING UNIT CU-1. FC-1 IS DESIGNED TO PROVIDE 900 CFM OF 100% OUTSIDE AIR. EF-1 IS DESIGNED TO EXHAUST 910 CFM. FC-1 IS CONTROLLED BY A WALL MOUNT THERMOSTAT. THE FAN SPEED OF EF-1 CAN BE MANUALLY

ADJUSTED BY A WALL MOUNTED CONTROL.

THE EXISTING HVAC SYSTEM SERVING ANIMAL ROOM 6 INCLUDES FAN COIL FC-2, EXHAUST FAN EF-2, AND CONDENSING UNIT CU-2. FC-2 IS DESIGNED TO PROVIDE 900 CFM OF 100% OUTSIDE AIR. EF-2 IS DESIGNED TO EXHAUST 910 CFM. FC-2 IS CONTROLLED BY A WALL MOUNT THERMOSTAT. THE FAN SPEED OF EF-2 CAN BE MANUALLY

ADJUSTED BY A WALL MOUNTED CONTROL.

NEW/MODIFIED HVAC SYSTEM AND CONTROLS DESCRIPTION

EXISTING EQUIPMENT FC-1, FC-2, EF-1, EF-2, CU-1, AND CU-2 WILL BE DEMOLISHED AND REPLACED WITH NEW COMMERCIAL QUALITY EQUIPMENT OF THE SAME APPROXIMATE CAPACITY AND CONFIGURATION. EXISTING SUPPLY DUCTING WILL BE DEMOLISHED. EXISTING EXHAUST DUCTING WILL BE CLEANED AND REMAIN IN PLACE.

NEW CONTROLS WILL INCLUDE TEMPERATURE AND PRESSURE CONTROL FOR EACH ANIMAL ROOM. A NEGATIVE PRESSURE WILL BE AUTOMATICALLY MAINTAINED BY MEASURING THE SUPPLY AND EXHAUST FLOW RATES FOR EACH ROOM AND APPLYING A CONSTANT NEGATIVE ~150 CFM (ADJ) SUPPLY OFFSET FROM THE EXHAUST CFM FLOW RATE. THE FLOW RATE IN EACH ANIMAL ROOM WILL BE CONSTANT VOLUME, BUT MANUALLY ADJUSTABLE FROM 10-15 AIR CHANGES PER HOUR, VIA A WALL MOUNTED CONTROLLER. THE OCCUPIED AIR FLOW RATE FOR ROOM 6 CAN BE ADJUSTED FROM 10 AC/HR (655 CFM) TO 16 AC/HR (1,050 CFM). THE UNOCCUPIED (NO ANIMALS) AIR FLOW

RATE FOR ROOM 6 CAN BE ADJUSTED AS LOW AS 8 ACH/HR (525 CFM).

THE OCCUPIED AIR FLOW RATE FOR ROOM 7 CAN BE ADJUSTED FROM 10 AC/HR (705 CFM) TO 15 AC/HR (1,050 CFM). THE UNOCCUPIED (NO ANIMALS) AIR FLOW RATE FOR

ROOM 7 CAN BE ADJUSTED AS LOW AS 8 ACH/HR (525 CFM).

SEQUENCE OF OPERATIONS

ANIMAL ROOMS SYSTEM DESCRIPTION:

EACH ANIMAL ROOMS HVAC SYSTEM INCLUDES A FAN COIL UNIT WITH A CONDENSING UNIT AND AN EXHAUST FAN. THE FAN COIL UNIT PROVIDES FILTERED AND TEMPERED AIR FOR COOLING AND VENTILATION. COOLING IS SUPPLIED BY THE DX COIL AND ASSOCIATED CONDENSING UNIT. THE FAN COIL UNIT PROVIDES 100% OUTSIDE AIR AND WILL BE ON AT ALL OCCUPIED HOURS. THE EXHAUST FAN FOR EACH ANIMAL ROOM WILL EXHAUST 150 MORE CFM THAN WHAT IS SUPPLIED BY THE FAN COIL UNIT TO KEEP THE ROOM NEGATIVE TO THE ADJACENT

CORRIDOR.

ANIMAL ROOMS - HVAC SYSTEM CONTROL:

1. EACH FAN COIL UNIT AND EXHAUST FAN WILL OPERATE TO PROVIDE COOLING AND VENTILATION AT ALL

OCCUPIED HOURS.

2. EACH FAN COIL UNIT IS A CONSTANT VOLUME SYSTEM AND WILL PROVIDE THE AIRFLOW REQUIRED

BASED ON THE MODE OF OCCUPATION AS SENSED BY THE RESPECTIVE EBTRON AIRFLOW

MEASUREMENT DEVICE THE CFM WILL BE AUTOMATICALLY ADJUSTED BASED ON THE EXHAUST FANS CFM AND EACH FAN COIL UNIT WILL PROVIDE 150 CFM LESS THAN THE EXHAUST FAN IS EXHAUSTING.

3. EACH ANIMAL ROOM COOLING TEMPERATURE SETPOINT IS 75°F (ADJ) AS SENSED BY THE THERMOSTAT IN THE ROOM AND IS PROVIDED AS AN INPUT TO THE ASSOCIATED WALL MOUNT TOUCH SCREEN DEVICE.

EACH FAN COIL UNIT SUPPLY AIR TEMPERATURE (SAT) SETPOINT IS 60°F (ADJ). EACH CONDENSING UNITS COMPRESSOR WILL MODULATE BETWEEN 10% AND 100% CAPACITY TO ACHIEVE THE SAT SETPOINT.

4. EACH EXHAUST FAN IS A CONSTANT VOLUME SYSTEM AND WILL EXHAUST 150 CFM MORE THAN THE ASSOCIATED FAN COIL UNIT IS SUPPLYING AS SENSED BY THE EBTRON AIRFLOW MEASUREMENT DEVICE UPSTREAM OF THE EXHAUST FAN. EACH EXHAUST FAN ALSO HAS AN EXHAUST AIR DAMPER THAT WILL BE INTERLOCKED WITH THE EXHAUST FAN. WHEN THE EXHAUST FAN IS ON THE DAMPER WILL BE OPEN AND

WHEN THE EXHAUST FAN IS OFF THE DAMPER WILL BE CLOSED.
