Description of the Required Services The purpose of the overall project is to replace aging roof top air conditioning units (RTUs) located above the Portland Terminal Radar Approach Control (TRACON) facility in the Portland International Airport in Portland, Oregon. There are four units which make up two sets of redundant units. The existing units were installed in 1994. Two (2) each are 12.5 ton Trane Model # TCH150B300CA units; and two (2) each are 25 ton Trane Model # TCH300B300CA units. The goal is to improve reliability as well as efficiency with new equipment, reducing energy consumption and costs for the facility over the life cycle of the equipment. Roof Top Unit Proposed Specifications2.1Common requirements for all RTUs 2.1Basic: EER for RTU's will be a minimum of 11.2 EER for 25 ton units and 11.5 EER for 12.5 ton units IAW ASHRAE 90.1-2007, refrigerant will be R-410, indoor sound power ratings max of 90 dB(A) IAW ARI Standard 270. Units shall meet the requirements of ASHRAE 90.1 - 2007 and applicable addenda. 2.2Unit Construction: Galvanized steel construction with exterior painted with factory finish capable of withstanding salt spray test of 500 or more hours IAW ASTM B117. All access doors will be hinged, hardware shall be heavy duty doors shall have two or more quarter-turn, tooless latches or handles. Access panels and/or doors secured by mechanical fasteners are not acceptable. Access doors will be provided to fans, motors, belts, controls, evaporator and condensing coils and dampers. Insulated double wall construction or foil faced 1" insulation with an R value of 4, edges of foil faced insulation will be edge bound or otherwise restrained to prevent erosion of fiberglass insulation at edges. 2.3Coils: Evaporator and condenser coils shall be of the direct expansion, draw-thru design. Evaporator and condenser coils shall have aluminum plate fins mechanically bonded to seamless enhanced copper tubes with all joints brazed. Coils shall be leak tested at the factory to ensure the pressure integrity. Coils shall have a minimum of 4 rows and a maximum of 12 fins per inch. Condensate pan shall be slide out design, constructed of a non-corrosive material, internally sloped and conforming to ASHRAE 62-B9 standards. 2.4Evaporator fan section: Belt driven, forward curve centrifugal fans, with adjustable sheaves, internal spring isolation of fan and motor, belt guard for safety, motors shall be premium efficiency type, 3 phase, 60 Hz, 208 volt, 2.5Compressors: Each unit will be provided with two or more high efficiency scroll type compressors. Provide low ambient cooling down to 0F, including the following as necessary: continuous fan operation, crankcase heaters, thermal expansion valves, frostat. 2.6Electrical: Provide internally mounted factory supplied disconnect switches with each unit. Switch will be accessible from outside the unit and include power lockout capability. Provide a GFCI protected convenience outlet at each unit. 2.7Controls: Controls will be factory installed and integral to the unit. Units and controls will be commissioned prior to shipment. Unit controls will operate independently from any building automation system. Provide unit control modules located at each unit with a user interface and a similar interface screen with status, setpoints and alarms in respective locations in the equipment room and near the TRACON operations area shown. Modules in respective spaces will combine inputs from each respective redundant RTU units. Control modules will be provided as part of the RTU unit. 2.8Outside Air: Economizer cooling is not required and will not be used on these units IAW ASHRAE 90.1 exceptions listed under section 6.5.1 c & d. Outside air intake will be sized to minimum outside air based on ASHRAE 62.1 requirements. Motorized two position dampers will be set in final position as part of system air balance. Damper blades will be gasketed with side seals to provide an air leakage rate of 4 cfm / square foot of damper area at 1" differential pressure per ASHRAE 90.1. Leakage rate will be tested in accordance with AMCA Standard 500. 2.9RTU Sequence of Controls: 2.9.1. Redundant RTUs will operate in lead/lag mode. Units will alternate lag/lead operation monthly, adjustable by user input at control panel. Lead unit will modulate cooling and heating coils to main space temperature setpoints. 2.9.2.In the event of a lead unit failure, the lag unit will be activated. Operation of supply and return isolation dampers for each unit, following shut down of malfunctioning unit and prior to start of back up unit, will be designed to minimize delay time to ensure space temperatures are returned to setpoint settings. If the lead unit is unable to maintain the space temperature setpoint below a user determined level (initially 80F) or above a user determined set point (initially 65F) for a user determined amount of time (initially 15 minutes) the lead unit will shut down and the lag unit will be activated, a local alarm will be initiated. An additional digital/analog output point will be provided for each unit to connect to user determined remote alarm location. (Wiring/connection of the point to the remote alarm location is not included in this contract.) 2.9.3.Provide an adjustable time delay between shut down of one unit and start up of second unit to allow isolation dampers to operate.
