About this file

Written by GovTribe AI · Apr 16, 2025

This document is a detailed set of mechanical and control system design drawings for an FAA Control Tower System Upgrade located in Little Rock, Arkansas. The comprehensive drawing set, prepared by Powers of Arkansas, covers multiple system components including air handling units (AHU-81.91 and AHU-1), variable refrigerant flow (VRF) systems, condensing units (CRU-1,2,3), exhaust fans, hot water systems, and associated control panel configurations.

The drawings provide extensive technical specifications for replacing existing HVAC controls and equipment, featuring Siemens Apogee automation systems and network layouts. Key technical elements include new DDC (direct digital control) controllers, temperature and humidity sensors, damper actuators, communication interfaces, and control panel migrations. The design emphasizes system integration, remote monitoring capabilities, and sequential operational sequences for various mechanical systems like air handlers, exhaust fans, and hot water pumps. The upgrade appears designed to modernize the facility's environmental control infrastructure with advanced, networked control technologies.

The constant volume air handling unit consists of a mixed air section with outdoor air and return air dampers, pre-filter, DX cooling coil, gas heating section and supply fan. The unit is DDC controlled using electric actuation.

The air handling unit is scheduled for automatic operation on a time of day basis for Occupied and Unoccupied modes.

Within the Occupied mode, the system can enter the Warm-Up mode when the space temperature is below set point or the Cool-Down mode when the space temperature is above set point. The system stays in the Warm-Up or Cool-Down mode until the mode set point is satisfied. Within the Unoccupied mode, Night Heating is available when the space temperature drops below 65 degrees F (18 degrees C) and Night Cooling is available when the space temperature rises above 85 degrees F (29 degrees C). The latest start time is the scheduled occupancy for the space.

The air handling unit operates in Warm-Up, Cool-Down, Occupied, Unoccupied, Night Heating, Night Cooling and Safety modes as follows (All suggested set points and settings are adjustable.):

Occupied

The supply air temperature set point is reset based on the room temperature set point.

The fan starts or continues to run and the unit is controlled as follows:

When the outside air dry bulb temperature is below the economizer changeover value, the mixing dampers modulate with the gas heating and DX cooling staging to maintain supply air temperature set point with a low limit of 48 degrees F

(9 degrees C) at the mixed air sensor. The mixing dampers ramp open slowly to minimize overshooting.

When the outside air dry bulb temperature is above the economizer changeover value, the mixing dampers are placed in the minimum outdoor air position. The gas heating and DX cooling stage in sequence without overlap to maintain the supply air temperature set point.

Return air humidity overrides control of DX cooling to maintain 55% relative humidity.

Unoccupied

The supply fan is off, the DX cooling is off, gas heating is off and mixing dampers close to the outdoor air.

Night Heating

The supply fan starts with the gas heating staging to maintain the supply air temperature set point for a minimum space temperature of 65 degrees F (18 degrees C). The DX cooling remains off and the mixing dampers are closed to the outdoor air.

Night Cooling

The supply fan starts with the DX cooling staging and mixing dampers modulating in sequence without overlap to maintain the supply air temperature set point for a maximum space temperature of 85 degrees F (29 degrees C). When the outside air dry bulb temperature is above the economizer changeover value, the mixing dampers are closed. The gas heating remains off.

Safety

Smoke detectors in the supply and return air streams de-energize the supply fan upon activation. The DX cooling and gas heating are off. All dampers position to their normal position after the fan is de-energized.

A current switch is installed in the supply fan starter. The DDC system uses this switch to confirm the fan is in the desired state (i.e. on or off) and generates an alarm if status deviates from DDC start/stop control.

AIR HANDLING UNIT NO.1:

THE UNIT WILL BE STARTED AND STOPPED IN ACCORDANCE WITH A PREDEFINED

TIME SCHEDULE. WHEN THE UNIT STARTS THE OSA DAMPER WILL OPEN TO ITS

MINIMUM POSITION SETTING. THE CONTROLLER WILL MODULATE THE SUPPLY

FAN INLET VANE DAMPER TO MAINTAIN SUPPLY DUCT STATIC PRESSURE

SETPOINT. THE CONTROLLER WILL CYCLE THE DX COOLING COMPRESSOR AS

REQUIRED TO MAINTAIN DISCHARGE AIR TEMPERATURE SETPOINT OF 55 DEG F

(ADJUSTABLE). THE CONTROLLER WILL OPERATE THE UNIT IN A HEATING MODE

WHEN THE RETURN AIR TEMPERATURE DROPS BELOW 60 DEG (ADJUSTABLE). IN

THE HEATING MODE THE OSA DAMPER WILL CLOSE, HOT WATER FLOW CONTROL

VALVE WILL MODULATE TO FULL OPEN POSITION, AND THE INLET GUIDE VANES

WILL BE REFRENCED TO 100 PERCENT. THE ASSOCIATED VAV BOX PRIMARY AIR

DAMPERS WILL BE FULLY OPEN AND THE ZONE SPACE SENSORS WILL OPEN HOT

WATER FLOW CONTROL VALVES TO MAINTAIN 68 DEGREES (ADJUSTABLE)

SETPOINT. WHEN THE RETURN AIR RISES TO 65 DEGREES F (ADJUSTABLE),

THE AHU WILL RETURN TO THE COOLING MODE. DUCT MOUNTED SMOKE DETECTOR
