- Description
- The Naval Surface Warfare Center Carderock Division (NSWCCD) is issuing a Sources Sought synopsis from all potential sources who may have technologies or systems relating to the supply of non-magnetic (or low magnetic permeability) air conditioning and refrigeration equipment for mine countermeasures ships. The Navy is considering modernizing all or portions of its existing machinery used to produce chilled water for shipboard air conditioning. The Navy is also considering modernizing all or portions of its machinery used for refrigeration of ships stores. Presently, these systems utilize open drive non-magnetic reciprocating compressors with sea water cooled condensers, although the Navy is considering all potential technologies. Equipment must be capable of conforming to MIL-S-901D grade A shock requirements, MIL-STD-167-1A vibration requirements, and MIL-STD-461F EMI requirements. Materials must have a relative magnetic permeability of 2.0 or less (by measurement in accordance with MIL-I-17214) after fabrication except for materials that must be magnetic due to function. Potential vendors must be able to meet latest Department of Defense acquisition restrictions on foreign sources of supply for specialty metals (10 USC 2533, DFARS Part 252). The Navy is interested in two potential options for air conditioning machinery: 1. Replacement of air conditioning plant - The chilled water air conditioning plant would need to provide at least 35-tons of cooling capacity with 28-85 degree F seawater inlet temperatures and 44 degree F chilled water outlet temperature. Ability to maintain capacity in higher seawater temperatures is preferred. Chilled water flow would be approximately 130 gallons per minute. Power consumption would be no greater than 44.7 kW at 440 VAC, 3-phase, 60 Hz shipboard electrical power in accordance with MIL-STD-1399. Size of plant: No greater than 70 in. (height) x 79 in. (width) x 92 in. (length), not including controller cabinet if required. Weight: No greater than 5294 lb. (wet), or 5000 lb. (dry), not including controller cabinet. 2. Replacement of Air Conditioning Plant Compressor - The compressor would need to be capable of being retrofitted onto an existing 35-ton chilled water plant. The compressor would be driven by a 60 HP motor at 1750 RPM and would need to have capacity control system for varying load conditions. Nominal operating conditions with refrigerant HFC-134a include a discharge pressure of 126 psig, suction pressure of 30 psig, and specific volume as saturated vapor 1.55 ft^3/lb. Size of compressor: No greater than 31 in. (height) x 34 in. (width) x 31 in. (length). The Navy is interested in two potential options for refrigeration machinery: 1. Replacement of Refrigeration Plant - The refrigeration plant condensing unit would need to provide 0.5-tons of cooling to maintain existing chill storeroom at temperatures of 33-36 degrees F and existing freeze storeroom at temperatures of -3 to 2 F. Seawater inlet temperature range to the condenser would be 28-85 degrees F, although ability to maintain capacity in higher seawater temperatures is preferred. Power consumption of the condensing unit would be no greater than 3.7 kW at 440 VAC, 3-phase, 60 Hz shipboard electrical power in accordance with MIL-STD-1399. Size of condensing unit: No greater than 68 in. (height) x 24 in. (width) x 48 in. (length), not including separate control cabinet if required. Weight of condensing unit: No greater than 1278 lb. (wet) or 1200 lb. (dry), not including separate control cabinet. 2. Replacement of Refrigeration Plant compressors - The compressor would need to be capable of being retrofitted onto an existing 0.5-ton refrigeration condensing unit, belt-driven from a 5 HP motor at 1165 RPM, operating with refrigerant HFC-134a. Nominal compressor suction and discharge pressures would be 4" Hg vacuum and 135 psig respectively, with condensing water temperature of 105 degrees F. Size: No greater than 20 in. (height) x 20 in. (width) x 18 in. (length). Responses: U.S. and foreign firms interested in being considered should submit, in writing, a description of their product and technical specifications which fulfill the Navy's requirements, or how it can be easily modified to meet these requirements, along with an estimated price and availability.Responses are required no later than 16 July 2010. All questions may be submitted electronically to craig.hollish@navy.mil. All information provided will be treated as Business Sensitive and will not be shared outside of Government activities and agencies without the permission of the provider. All information shall be provided free of charge to the Government. NSWCCD may request further information regarding the capabilities of respondents to meet the requirements, and may request a presentation and / or site visit as deemed necessary. This announcement is a request for information only and is not a request for proposal or announcement of solicitation. The Government will not pay for any material provided in response to this synopsis nor return any of the data provided. All responding firms will be contacted and may be requested to exchange information with Navy personnel. Replies should be sent to Naval Surface Warfare Center Carderock Division, 5001 South Broad Street, Philadelphia, PA 19112-1403, Attn: Mr. Craig Hollish, Code 921 Phone: 215-897-8032, E-Mail: craig.hollish@navy.mil
