About this file

Written by GovTribe AI · Jun 27, 2025

The provided file is a comprehensive set of architectural and engineering design drawings for the Server Room Cooling System project for the Greater Dayton Regional Transit Authority (GDRTA), located at Wright Stop Plaza in Dayton, Ohio. The project involves replacing the HVAC unit in the server room and associated electrical support work, with specific focus on the second floor and roof areas of the facility. The design documents include detailed mechanical, electrical, and demolition plans, covering aspects such as equipment placement, ductwork, piping, electrical connections, and system integration. The project involves installing a new CRAC (Computer Room Air Conditioning) unit, a condensing unit, and a steam humidifier, with careful consideration for existing building systems and infrastructure.

The technical specifications indicate a complex retrofit project with precise environmental control requirements for the server room. The new cooling system is designed to maintain a consistent humidity level of 40% relative humidity, with integrated control systems that will communicate with the building's DDC (Direct Digital Control) system. Electrical connections will be made to existing emergency distribution panels (EDP2 and EMB), with specific voltage and amperage requirements for each piece of equipment. The project includes detailed provisions for equipment mounting, refrigerant piping, electrical connections, and necessary demolition and repair work, ensuring minimal disruption to the existing facility while upgrading the critical server room cooling infrastructure.

1. GENERAL:

THE COMPUTER ROOM AIR HANDLING (CRAC) UNIT CONSISTS OF RETURN AIR FILTERS, DX COOLING

COIL, ELECTRIC REHEAT COIL, AND SUPPLY FAN.

THE COMPUTER ROOM AIR HANDLING UNIT SHALL BE CONTROLLED THROUGH A FACTORY

PROGRAMMED APPLICATIONS CONTROLLER.

THE CRAC UNIT SHALL OPERATE AS A SINGLE ZONE VARIABLE AIR VOLUME UNIT.

THE CRAC UNIT SHALL OPERATE AS NECESSARY TO SATISFY SPACE TEMPERATURE SETPOINTS 24/7.

SPACE TEMPERATURE SETPOINT SHALL BE 74°F (ADJUSTABLE) FOR COOLING AND 70°F (ADJUSTABLE)

FOR HEATING.

THE CRAC UNIT SHALL OPERATE AS NECESSARY TO SATISFY MAXIMUM HUMIDITY SETPOINTS 24/7.

SPACE MAXIMUM HUMIDITY SETPOINT SHALL BE 65%RH (ADJUSTABLE). ANY REQUIREMENT TO

INCREASE HUMIDITY MUST BE MET BY THE STAND ALONE HUMIDIFIER.

ALL ALARMS SHALL BE MONITORED BY THE CRAC UNIT CONTROLLER AND SIGNALED TO THE DDC

FRONT END.

2. SUPPLY FAN:

OPERATION:

IN COOLING OR DEHUMIDIFICATION MODE, AND UPON A CALL FOR COOLING, THE SUPPLY FAN VFD SHALL BEGIN OPERATION AT 30% AND MODULATE BETWEEN 30% AND 100% AS NEEDED TO MAINTAIN

THE SPACE TEMPERATURE SETPOINT.

IN HEATING MODE, AND UPON A CALL FOR HEATING, THE SUPPLY FAN VFD SHALL BEGIN OPERATION

AT 50% AND MODULATE BETWEEN 50% AND 100% AS NEEDED TO MAINTAIN THE SPACE

TEMPERATURE.

SUPPLY FAN OPERATION SHALL BE VERIFIED THROUGH UNIT CONTROLLER. IF THE SUPPLY FAN IS

NOT OPERATIONAL, THE UNIT CONTROLLER SHALL SIGNAL AN ALARM TO THE DDC PANEL.

3. DX COOLING COIL:

OPERATION:

COMPRESSOR SHALL MODULATE TO MAINTAIN LEAVING COIL TEMPERATURE SETPOINT OF 55°F

(ADJUSTABLE). ALARM SHALL BE SENT TO THE DDC IF THE SUPPLY AIR TEMPERATURE DROPS BELOW

40°F (ADJUSTABLE). MANUAL RESET IS REQUIRED.

4. ELECTRIC REHEAT COIL:

OPERATION:

ELECTRIC REHEAT COIL SHALL BE STAGED TO MAINTAIN SPACE TEMPERATURE OR SPACE RELATIVE HUMIDITY SETPOINT. ALARM SHALL BE SENT TO THE DDC IF THE SUPPLY AIR TEMPERATURE DROPS BELOW 40°F (ADJUSTABLE). UNIT SHALL SHUT UPON ALARM SIGNAL BEING SENT. MANUAL RESET IS

REQUIRED.

SEQUENCE OF OPERATION - CRAC-1/ACCU-1:

5. HUMIDITY CONTROL:

UPON DROP IN SPACE HUMIDITY BELOW 45% (ADJ.), REMOTE HUMIDITY CONTACTOR SHALL CLOSE TO

ENABLE HUMIDIFICATION BY REMOTE HUMIDIFIER (H-1).

6. FILTER MAINTENANCE:

DIFFERENTIAL PRESSURE SWITCH WITH SENSOR TAPS ON UPSTREAM AND DOWNSTREAM SIDE OF

THE MAIN FILTER BANKS SHALL SIGNAL CRAC UNIT CONTROLLER WHEN THE DIFFERENTIAL RESSURE IS EQUAL TO OR GREATER THAN THE SET POINT OF 0.5 IN WG. THE CONTROLLER SHALL INITIATE A

MAINTENANCE ALARM SIGNAL INDICATING A DIRTY FILTER.

7. FIRE ALARM SIGNAL:

ANY SIGNAL FROM THE FIRE ALARM SYSTEM DEDICATED TO THE SERVER ROOM SHALL DE-ENERGIZE

THE SUPPLY FAN, AND NOTIFY THE DDC SYSTEMS. THE DDC SYSTEM SHALL RETURN ALL

CONTROLLED ITEMS TO THEIR SHUTDOWN POSITION. MANUAL RESET IS REQUIRED.

8. BAS MONITORING POINTS:

AT TIME OF INSTALLATION, A DDC SYSTEM WILL NOT BE AVAILABLE TO CONNECT TO; HOWEVER, PROVISIONS SHOULD BE MADE FOR FUTURE CONNECTION. ONCE A DDC SYSTEM IS AVAILABLE, THE CRAC UNIT CONTROLLER SHALL COMMUNICATE THE FOLLOWING POINTS TO BE MONITORED BY THE

DDC SYSTEM VIA A BACNET PROTOCOL:

· SPACE TEMPERATURE

· SPACE HUMIDITY

· ALARM STATUS (GENERAL)

· COMPRESSOR PERCENTAGE

· ELECTRIC REHEAT COIL LEAVING AIR TEMPERATURE

· UNIT LEAVING AIR TEMPERATURE

9. ALARMS:

THE CRAC UNIT CONTROLLER SHALL BE ABLE TO COMMUNICATE THE FOLLOWING ALARMS TO THE

DDC SYSTEM:

· SUPPLY FAN FAILURE

· HIGH SUPPLY AIR TEMPERATURE ALARM (120°F) (ADJUSTABLE)

· LOW SUPPLY AIR TEMPERATURE ALARM (40°F) (ADJUSTABLE)

· HIGH SPACE TEMPERATURE ALARM (85°F) (ADJUSTABLE)
