4. NOTES:

4.1. Chiller Capacity & Utilities:

4.1.1. Cooling: The minimum nominal chilled water capacity shall be as indicated with the actual capacity, based on an ambient temperature of 95ºF dry bulb with an Entering Water Temperature (EWT) of 52ºF and a Leaving Water Temperature (LWT) of 42ºF, to be not less than 5% of the desired nominal capacity. The unit capacity shall not be greater than one-third above (+⅓) the minimum specified capacity and shall be able to run continuously at one-quarter of that unit's stated capacity.

4.1.2. Automatic Operation, Regulation, & Controls: The Chiller shall be equipped with an automatic variable capacity control requiring only initial temperature adjustment from 38 to 60°F by the operator. The Chiller shall be fully controllable under a wide range of loads even though the daily and seasonal ambient temperatures vary greatly.

4.1.3. Design & Component Integration: The Chiller can either be an integrated Chilled Water Unit capable of both refrigerating and pressurizing water or can be two separate types of components consisting of a Chiller that refrigerates water and a Pump Module that pressurizes water. The unit / modules shall be designed for continuous operation at minimal loading (i.e. one-quarter of full capacity for refrigeration & one-third of full capacity for pumping) despite extreme ambient conditions (e.g. –10 to +100°F and 0 to 100% RH).

4.2. Coolant Free:

Besides manifolds and hose assemblies that are normally flushed and tested, all machinery conveying chilled water such as: the Chiller, Pump and machines with a chilled water coil; shall arrive with no coolant of any type in its piping (i.e. No Water & No Anti-Freeze).

4.3. Chilled Water Hose Assembly / Manifold Construction / Cooling Coil Hydrostatic Testing:

All Chilled water connectors / fittings must be quick disconnect style fittings meeting the requirements defined in reference 2.1.1.2. Chilled Water Hose assemblies shall be non-collapsible and the camlock fittings shall be attached to the hose material via the more secure, newer type, crimp style hose fitting via a single specified diameter, elongated sleeve length and not from the less secure, older type, band clamp style hose fitting via multiple universal diameters, shorter ferrules. Gaskets for couplings shall be pre-installed inside the female coupling(s) of hose assemblies and manifolds. The gasket shall be inspected for presence, tight fit, and lack of deterioration. Gaskets shall not protrude into the waterway. A gasket with a smaller diameter than that of the recess can cause a leaky connection when pressure is applied.

Hose/manifold/valve assemblies and all cooling coils shall be hydrostatically tested with new hose gaskets for Strength and Tightness and/or Valve Seat Leakage by an independent (of the Contractor) and certified Vendor to a minimum of 150 psig for five minutes and visually inspected and/or internal valve leakage measured while pressurized. Hydrostatic test date shall be within one calendar year of scheduled Arrival Date of the equipment. Hoses/manifolds/valve assemblies shall have a banded identification (ID) tag or label attached to the assembly displaying the hydrostatic test results. The Hydrostatic Test Certificates issued by the certified testing facility shall provide a copy of the certificates to the Contracting Officer Representative (COR).

4.4. Phase Rotation:

To prevent or identify an out-of-phase electrical power situation, three-phase machines shall include either:(a) a reverse phase relay and/or meter that identifies an out-of-phase condition and prevents operation in which such a condition could cause damage or (b) an arrow prominently displayed at an appropriate location on the machine's housing to indicate the proper direction of shaft rotation with the ability to observe a portion of the shaft after a momentary application of power (a.k.a. jog or bump). A reverse phase relay is not required nor desired for VFD motors, however, the VFD shall have a jog button so as to verify correct rotation.

4.5. Supplemental Equipment:

For the protection and cleanliness of the machinery components, all chilled water connection points shall be shipped with plug/cap fittings.

4.6. Hydronic Flow Meter:

Attached to the Chiller and its associated pump shall be a continuous reading liquid flow meter, preferably, in-line with flow. The type of meter must be Electronic Metering. The physical positioning of the instrument shall be downstream of the Chiller immediately after its discharge. The flow meter assembly shall be rated for 150 psig; dimensioned for the nominal diameter pipework. The instrument shall be calibrated by a licensed Metrology Laboratory within five years of its scheduled delivery with certified calibration test results accompanying the flow meter assembly and reported via E-mail to the Contract Officer Representative

(COR).

4.7. Freeze protection:

4.7.1. Season:

For cold weather geographic regions including Portsmouth NH and New London CT, the all-season chiller and its accompanying pump are machines that have the potential for its chilled water coils or other piping components to freeze sometime during the Freezing Prevention season (Oct 1st – Apr 30th) causing considerable damage to the unit.

4.7.2. Low Ambient Temperature & Low Cooling Load:

As an all-season (year-round) continuously operating chiller, the unit must be able to function at very low ambient temperatures and at low cooling loads of one-quarter or less of its full-load or a combination of both substantially below freezing weather and low load conditions. This low ambient and low load chiller shall be capable of producing 55ºF chilled water with no antifreeze during the freezing prevention season.

4.7.3. Seasonal Resets of The Leaving Chilled Water Temperature:

Prior to commencement of the freezing prevention season, the Vendor shall reset the discharge leaving chilled water temperature from 42ºF to 55ºF. Soon after (within a month of) termination of the freezing prevention season, the Vendor shall reset the discharge leaving chilled water temperature from 55ºF to 42ºF thus, maximizing the potential load capacity of the chiller. The Vendor shall schedule and coordinate with the Project.

4.8. Noise Requirement:

When operating at full speed, noise levels must not be over 105 dB[A] and preferably, 85 dB[A] or less at six feet from the unit or frame unless a quieter noise level is specified. A hearing protection safety placard shall be posted on each machine generating more than 85 dB[A] at the unit's edge or frame.

4.9. Machinery / Equipment Tagging and Markings:

Fluid piping inlet(s) / outlet(s) must be clearly marked. Machinery and itemized equipment require tagging to show Project Number / Technical Specification Identification (ID) Number.

4.10. Vendor Identification of Itemized and Ancillary Equipment:

The Contractor shall uniquely tag and permanently mark all of its ancillary and itemized equipment / hardware (e.g. manifolds, hose assemblies, pipe fittings, duct adapters, ducting, etc.) so as to differentiate from that owned by either the Shipyard or other Vendors.
