Abstract: Air, Thermal and Water Management for PEM Fuel Cell Systems

Description: PEM fuel cells are excellent candidates for transportation applications due to their high efficiencies. PEM fuel cell Balance of Plant (BOP) components, such as air, thermal, and water management sub-systems, can have a significant effect on the overall system performance, but have traditionally not been addressed in research and development efforts. Recognizing this, the U.S. Department of Energy and Honeywell International Inc. are funding an effort that emphasizes the integration and optimiz… more

Check-Testing of Manufacturer Self Reported Labeling Data & Compliance with MEPS

Description: China first adopted minimum energy performance standards (MEPS) in 1989. Today, there are standards for a wide range of domestic, commercial and selected industrial equipment. In 1999, China launched a voluntary endorsement label, which has grown to cover over 40 products including water-saving products. Further, in 2005, China started a mandatory energy information label that initially covered two products and in 2007 was extended to cover four products total including: air conditioners; house… more

Commercial Off-the-Shelf (COTS) Components and Enterprise Component Information System (eCIS)

Description: The purpose of the project was to develop the processes for using commercial off-the-shelf (COTS) parts for WR production and to put in place a system for implementing the data management tools required to disseminate, store, track procurement, and qualify vendors. Much of the effort was devoted to determining if the use of COTS parts was possible. A basic question: How does the Nuclear Weapons Complex (NWC) begin to use COTS in the weapon Stockpile Life Extension Programs with high reliability… more

Benchmarking and Equipment and Controls Assessment for a 'Big Box' Retail Chain

Description: The paper describes work to enable improved energy performance of existing and new retail stores belonging to a national chain and thereby also identify measures and tools that would improve the performance of 'big box' stores generally. A detailed energy simulation model of a standard store design was developed and used to: (1) demonstrate the benefits of benchmarking the energy performance of retail stores of relatively standard design using baselines derived from simulation, (2) identify cos… more

Development of an Integrated Residential Heating, Ventilation, Cooling, and Dehumidification System for Residences

Description: The Need and the Opportunity Codes such as ASHRAE 90.2 and IECC, and programs such as Energy Star and Builders Challenge, are causing new homes to be built to higher performance standards. As a result sensible cooling loads in new homes are going down, but indoor air quality prerogatives are causing ventilation rates and moisture loads to increase in humid climates. Conventional air conditioners are unable to provide the low sensible heat ratios that are needed to efficiently cool and dehumidif… more

Microhole Coiled Tubing Bottom Hole Assemblies

Description: The original objective of the project, to deliver an integrated 3 1/8-inch diameter Measurement While Drilling (MWD) and Logging While Drilling (LWD) system for drilling small boreholes using coiled tubing drilling, has been achieved. Two prototype systems have been assembled and tested in the lab. One of the systems has been successfully tested downhole in a conventional rotary drilling environment. Development of the 3 1/8-inch system has also lead to development and commercialization of a sl… more

Gundrilling Oil Evaluation to Find a Replacement for 50-50

Description: In 2006 the gundrilling oil used at Honeywell FM&T (Federal Manufacturing and Technology) was known as 50-50. This name was selected because the oil is a mixture of two machining oils, Milpro 634 and Pennex N47. Unfortunately, Honeywell FM&T was notified that one component, Pennex N47, would be discontinued by the manufacturer. At this point the Honeywell FM&T team decided to select a single oil to eliminate mixing and procurement of two products. In addition, the team also wanted to select new… more

International Experience in Standards and Labeling Programs for Rice Cookers

Description: China has had an active program on energy efficiency standards for household appliances since the mid-1990s. Rice cooker is among the first to be subject to such mandatory regulation, since it is one of the most prevalent electric appliances in Chinese households. Since first introduced in 1989, the minimum energy efficiency standard for rice cookers has not been revised. Therefore, the potential for energy saving is considerable. Initial analysis from CNIS indicates that potential carbon savin… more
