WILMINGTON, DELAWARE

SEQUENCE OF OPERATIONS - BLDG.#13 AIR HANDLING UNITS

(TYPICAL FOR AHU-1 & AHU-2)

GENERIC AHU - SEQUENCE OF OPERATION

1. GENERAL

UNIT IS MANUALLY STARTED AND STOPPED BY THE DCP OR REMOTELY AT THE BMS. WHEN UNIT IS OFF DAMPER D-1 IS CLOSED. WHEN UNIT IS ON DAMPER D-1 IS OPEN.

2. TEMPERATURE CONTROL

DURING HEATING MODE THE SPACE TEMPERATURE SENSED BY T-1 SHALL BE MAINTAINED AT SETPOINT BY DCP MODULATING V-1. DURING COOLING MODE THE COOLING

COIL LEAVING AIR TEMPERATURE SENSED BY T-3 SHALL BE MAINTAINED AT SETPOINT BY DCP BY MODULATING V-2, AND THE SPACE TEMPERATURE SENSED BY T-1 SHALL

BE MAINTAINED AT SETPOINT BY MODULATING V-3.

3. AIR FLOW CONTROL

THE SUPPLY FAN SHALL RUN AT CONSTANT SPEED PROVIDING CONSTANT AIR FLOW.

4. FREEZE PROTECTION

IF THE AIR TEMPERATURE AS SENSED BY T-2 FALLS BELOW 45F AN ALARM SIGNAL IS INDICATED AT THE DCP AND BMS. IF THIS TEMPERATURE FALLS BELOW 40F THE UNIT

SUPPLY FAN SHALL STOP, THE DAMPER D-1 SHALL CLOSE AND A CRITICAL ALARM SHALL BE INDICATED AT THE DCP AND BMS.

5. EMERGENCY SHUTDOWN/RESTART

WHEN SMOKE IS DETECTED BY THE DUCT MOUNTED SMOKE DETECTOR THE SUPPLY FAN SHALL SHUT OFF, DAMPER D-1 CLOSE AND AN ALARM SIGNAL SHALL BE

TRANSMITTED TO THE FIRE ALARM SYSTEM. SUPPLY FAN SHALL RESTART AND DAMPER D-1 SHALL OPEN WHEN THE FIRE ALARM CIRCUIT IS MANUALLY RESET.
