HVAC SYSTEM NARRATIVE

A. Existing System

This system description is based on a review of the drawings for this building dated 15 July 1958. The primary heat source for Thule Air Base (TAB) is a central steam boiler plant located in Building 341 and 241 at the center of the base. JP-8 fuel is used to produce high pressure steam at approximately 5.2 bar (75psi). Steam is then distributed via above ground piping throughout the base to preserve the integrity of the permafrost.

A three inch high pressure (100 psi) steam line enters the First Floor Mechanical Room.

This is converted to low pressure steam at a pressure reducing station in the First Floor Mechanical Room. Low pressure steam is then provided to Heating and Ventilating Units on the First, Second, and Third Floor Mechanical Rooms. These units are rated approximately 2000 cfm. Each unit is equipped with an intake louver protected by a hood. Within each unit are two preheat coils, a reheat coil, and a humidifier. Steam condensate is collected in a condensate receiver on the First Floor and returned to the central steam boiler plant.

The Heating and Ventilating Units supply ventilation air to each dormitory unit using ductwork which is routed through cavities in the perimeter wall. Supply registers are located in this perimeter wall. Air supplied to the units is transferred to the corridor and re-enters the Mechanical Rooms via transfer grills from the Mechanical Rooms to the Corridors.

Exhaust air is collected within existing Rest Rooms and rises up shafts to two fan rooms on the third floor. Exhaust fans in these rooms discharge via roof ventilation monitors.

All existing piping, ductwork, and equipment in the building will be demolished as part of this project. Base steam and condensate will be demolished on site as far back needed to accommodate the new system.

Currently there are existing controls in the first floor mechanical room of building 97 that monitor the heat tracing of outside utilities (four sewage lines and one potable water line).

They were placed in the mechanical room due to the lack of space in the nearby utility shed #7018. These controls will be salvaged and returned to the government for future reuse and relocation.

B. Proposed HVAC System

The proposed system for the renovation of Building 97 is based on both the systems used in the “FY 13 Dormitory Project 100% submission documents dated November 5, 2012 and distribution pathways from the original drawings for Building 97 dated 15 July 1958.

SKM1,2, and 3, attached, show some features of this system.

As is appropriate for the climatic zone the building will be heated and ventilated but will not have cooling systems.

A 3” high pressure (448 kpa/65 psi) steam line and 3/4”condensate line currently serve the building. Calculations indicate that these lines have capacity to meet the loads of the

Building 97 renovation. Currently there are plans to replace high temperature steam lines with high temperature hot water lines. That project will not be completed soon enough for this project to be based on distribution of high temperature hot water.

Four steam to liquid flooded vertical heat exchangers will be provided in the new system.

One pair will provide heating hot water for room radiators. The second pair will provide 60% glycol/40% water heating fluid for Crawl Space Radiators, and for primary and defrost heating coils in heat recovery air handling units. Each heat exchanger of the pair will be sized at 100% capacity. One will be “duty” and the other will be the “standby” to provide

100% redundancy. The Design Build contractor’s design will include a provision of space so that in the future the steam based heat exchangers can be replaced with heat exchangers based on high temperature hot water.

A pair of circulating pumps will be provided associated with both hydronic loops. Each loop will have two pumps, each sized at 100% capacity. One will be the “duty and the other will be the “standby” to provide 100% redundancy. Associated with each hydronic loop are additional required components, including, but not limited to, air separators, expansion tanks, and control valves.

The heat exchangers, circulating pumps, and associated equipment may be located in either of two locations. Equipment may be in an Exterior Containerized Mechanical room or in

Interior Mechanical Rooms

a. Exterior Containerized System. Bid Option. All equipment needed to receive base steam, convert the heat energy to both hydronic loops, associated pumps, expansion tanks, control valves and DDC control system shall be built at a single location inside a standard size insulated shipping container, witness tested with government personnel as an assembly at the location of manufacture. The Exterior Containerized system shall be shipped to site, and installed adjacent to Building 97 in accordance with requirements for Exterior Mounted Equipment.

System function shall be tested again at site as part of normal construction testing and acceptance.

b. Interior Mechanical Room. Base Bid. All equipment needed to receive base steam, convert the heat energy to both hydronic loops, associated pumps, expansion tanks, control valves and DDC control system shall be built at Building 97 First Floor Mechanical Room. Testing shall be performed on site in Thule as part of the construction project.

Hydronic Radiators. There will be two types of hydronic radiators; Crawl space Radiators and Room Radiators. Crawl space radiators will be located in the Crawl Space below the first floor. They will be fed from the glycol/water hydronic loop. The purpose of these radiators is to keep plumbing and HVAC lines in the Crawl Space from freezing. Room

Radiators will be located in occupied spaces for comfort heating.

Ventilation air will be provided by energy recovery heating and ventilating units located within each floor’s mechanical room. The air intake and exhaust for the air handling unit will incorporate “arctic type outdoor hoods” and motorized air dampers to prevent entrainment of snow due to snow drift and negative system effects caused by high winds. There will be no roof penetrations as requested by Greenland Contractors (facility operators).

Dedicated Outdoor Air Ventilation Systems are to be sized to meet both the ventilation and pressurization requirements of the building, and provide tempered, filtered outdoor air to the occupied spaces, typically ducted directly to the occupied spaces.

Dedicated Outside Air Ventilation Unit with energy Recovery will include:

a. Supply fan with motor and variable frequency drive

b. Exhaust fan with motor and variable frequency drive

c. Energy recovery wheel for sensible and latent heat recovery.

d. Primary heating coil with 60% propylene glycol, 40% water heating fluid

e. Defrost coil with 60% propylene glycol, 40% water heating fluid

f. Dedicated unit DDC control panel with full communication with building DDC system.

g. Insulated R13 double wall casing

h. Casing window panels for inspection at each section.

i. Supply air acoustic silencer

j. Exhaust air acoustic silencer

k. MERV 8 exhaust filter

l. MERV 13 supply air filter with MERV 8 prefilter

Units shall have a fixed amount of exhaust air from bathrooms. They will have a variable amount of supply air for makeup of bathroom exhaust, kitchen exhaust, and dryer exhaust.

The supply air quantity will be raised depending on the number of kitchen and dryer exhaust fans which are operating. This shall not be done by measuring building pressure or using a sail switch. It shall be accomplished by positive signal by reading if the appliances are actually running (exhausting). Multiple units may be grouped together to receive a common signal if it is determined to facilitate easier controls/ operations.

BUILDING HVAC CONTROLS AND AUTOMATION

The basis of design will be Trend Control Systems Ltd. Trend provides the base wide

Energy Management and Control System (EMCS) at Thule Airbase.

A new BACnet-based Building Automation System (BAS) will be provided to control and monitor the mechanical equipment in the renovated Building 97. The new building control system will be an addition to the existing Trend Company Energy Management and Control

System (EMCS) currently installed at the Thule AFB. The new BAS will be a complete system provided with all the necessary hardware, software, and control devices. The BAS network will include controllers on the supervisory level and the unitary level. The BAS system will use BACnet-based controllers residing on a combination BACnet/IP network and

BACnet/MSTP platform. All input/output devices will communicate using the protocols and network standards as defined by ANSI/ASHRAE Standard 135-2004, BACnet.

The steam heat exchanger system will be provided with a dedicated control system. The controls associated with the new packaged redundant heat exchanger system including controller, control devices and BACnet interface will be provided by the packaged redundant heat exchanger system manufacturer. The system will communicate with the existing BAS system via a BACnet/MSTP over IP network interface for remote control and monitoring.

The air to air energy recovery ventilation unit will be controlled by a dedicated control system which is fully compatible with the base EMCS system.

Each room’s hot water radiators will be controlled by a non-electric thermostatic valve mounted on the unit, not through the BAS. The thermostat will modulate the hot water valve to maintain space temperature set point.

Domestic hot and cold water meters will be provided with BACnet communication interfaces to the BAS to allow remote reading, data storage, and trend logging. All meter information will be stored at the Supervisory Server for reporting, trend logging, archiving, and report printing.

The supply and exhaust air streams shall be provided with the following BACnet control points at a minimum: supply air intake outdoor air temperature and pressure, supply discharge air temperature and pressure, intake and exhaust air temperature at the heat-wheel, exhaust air inlet temperature and pressure, exhaust air temperature and pressure discharge before and after the defrost coil. There will also be a high limit and low limit pressure transmitter with alarm safety and shut-down for ductwork pressure safety protection at supply and exhaust duct main or fan.

Energy meters for space heating and energy meters for domestic hot water shall be provided. Each energy consumption component shall be a separate and distinct meter for data gathering purposes.

At the end of installation, functional testing, and system commissioning, the contractor will provide training to Thule base personnel on all aspects of the newly installed system, including, hardware and software.
