Request for Proposal

Air Handling Units

Posted 03/09/2011

Proposals are due by COB

3/23/2011

The proposal will include air handling unit, outdoor grill and wall sleeve for 54 units.   Price will include Delivery.  The units will run in cool mode 365 days a year but units will be required to have room freeze protection which activates at a room temperature of 40 degrees F or below. The vendors ability meet customers schedule will need to be discussed.  Since no onsite work will be required vii, viii, xii, xiv should not apply.  The equipment contract on the RFP home page will be used for this proposal.

 

 

 

Furnish air-cooled through-the-wall package terminal air conditioners and heat pumps (assembled in the USA).

Units are rated in accordance with the ARI (Air Conditioning & Refrigeration Institute) Standards 310/380-93, CSA (Canadian

Standards Association) EEV certification programs and ETL listed.

Ratings

Each unit must meet the following specifications:

ARI rating of 15,000 BTUH cooling (and 13,300 BTUH

reverse cycle heating with a COP of 2.9 at 47° F O.D.)

Electric resistance heat of 13,900 BTUH. Total Amp draw

must be of 7.0 Amps and 1465 Watts at 230/208 volts.

The unit must remove a minimum of 4.4 pints of

moisture per hour when operated at rating conditions. The EER

must be a minimum of 9.9 EER.

Unit Chassis

Each unit must be slide out design shipped with room cabinet

front installed. Unit chassis must have the ability to be installed

with 0 clearance from finished floor. An electrical power cord

must be included with chassis and installed by the manufacturer

to assure proper NEMA 6 or 7 configuration and UL-approved

length. Units less than 250 volts must also have a LCDI power cord.

Unit must be tested for conformance to ASTME water infiltration

specification ASTME 331-86, which ensures no water infiltration

when tested at 8" rain per hour at 63 mph wind for 15 minutes

Room Cabinet

The monochromatic front of the room cabinet must be able to

be field-secured to chassis to inhibit tampering. Filter must be

accessible without removing room front. Cabinet depth must

not exceed 7⅝” to minimize unit’s impact on room space.

Coils

Unit’s coils must have rifled copper tubing expanded into

rippled-edge louvered aluminum fins. Exterior coil must be of

a two-row slab coil design with removable shroud top to allow

easy-access for cleaning of the exterior coil.

Heat Pumps

Each unit must include a change-over thermistor that senses an

outside ambient switch-over temperature as low as 24°F, lockopen

refrigerant reversing valve during heat pump operation,

temperature-activated defrost drain and automatic emergency

heat operation to override the heat pump’s change-over

thermostat and bring on electric resistance heaters in the event

of a sealed system failure. Unit must not operate compressor

and electric heaters simultaneously.

Compressor

The compressor must be hermetically sealed, internally isolated,

rotary-type and permanently mounted on rubber isolators. No

removal or adjustment of compressor hold-down bolts is to be

required during installation.

Warranty

The warranty is for Full One Year on the entire unit; Full 2nd through

5th Year on the entire sealed refrigerant system components;

Limited Second through Fifth Year on functional parts only.

Evap orat or/Condenser Fans

Direct drive with a permanent, split-capacitor, two-speed indoor

motor. Condensate must be directed onto the back and sides of

the coil to aid in evaporation and removal.

Air Discharge

Must be a sloped surface so that obstructions cannot be placed

on the unit. Discharge conditioned air can be directed into the

room at an angle of 16 or 56 degrees from the vertical position.

The discharge grille must be of polycarbonate material to resist

bending, cracking, rusting and corrosion.

Wall Sleeves (WS900E)

The wall sleeve must be industry-accepted dimensions: 14⅛”

depth x 42” width x 16¹/₁₆” height and constructed of G90 HDG

galvanized steel with a baked corrosion-inhibiting urethane

primer and baked-polyester topcoat enamel. Sleeve must be

insulated and shipped with a weather resistant rear closure

panel installed.

Outdoor Grilles

Outdoor grille must be architecturally extruded, louvered

aluminum (AGK01*B), one-piece polymer-blend injection

molded louver (PGK01*B) or standard stamped aluminum

(SGK**B). All other grilles must be submitted to the PTAC

manufacturer for feasibility, airflow characteristics and

compliance with UL regulations, where necessary.
