ACES demonstration: construction, startup, and performance report

Description: A 2000-ft/sup 2/ single-family residence was constructed during the second quarter of 1976 to demonstrate the energy-conserving features of additional insulation, a ventilation cooling cycle, and the Annual Cycle Energy System (ACES). The ACES is an integrated heating and cooling system that supplies space heating, hot water, and space cooling using a heat pump and low-temperature thermal storage. Included in this report are a discussion of the construction techniques employed and the problems encountered during construction, a description of the ACES concept and the ACES mechanical package, and a discussion of the ACES performance and the experiences obtained during initial operation of the ACES. Continuous operation and data collection were begun in May 1977. Performance data from November 1977 through March 1978 have shown a seasonal heating coefficient of performance of 2.77 for the ACES, giving a 63% energy reduction compared to electric resistance space and water heating.

Acoustic location of infiltration openings in buildings. Final report

Description: Unnecessary air infiltration (''draftiness'') in buildings can be a major cause for excessive energy consumption. A method for using sound to locate, for subsequent sealing, the openings of air infiltration leakage paths in buildings has been investigated. The results of pertinent analytical studies, laboratory experiments, and field applications of this acoustic-location method are reported; and a plan is provided to encourage national implementation of the method. Low-cost, readily available equipment and procedures are described whereby the average building contractor or homeowner can use acoustic leak location to pinpoint many of the air infiltration openings in a building.

AES study of the adsorption of O/sub 2/, CO, CO/sub 2/, and H/sub 2/O on indium

Description: The adsorption of various oxygen-containing gases on clean polycrystalline In has been studied. For the In-O/sub 2/ system, the relationship between N(E) areas and dN(E)/dE peak heights for the In MNN Auger transition was found to be linear. At saturation, an oxygen/indium ratio of 3/2 was measured, consistent with the formation of the stable oxide In/sub 2/O/sub 3/. Low coverage sticking coefficients were found to be approximately .014 for O/sub 2/, approximately .004 for H/sub 2/O, approximately 5 x 10/sup -5/ for CO, and approximately 2 x 10/sup -5/ for CO/sub 2/. In each case, chemical shifts and peak distortions in the N(E) and dN(E)/dE spectra have been measured for the gas-saturated In, the largest being approximately 3 eV for the MNN transition of O/sub 2/-saturated surface.

Application of thermal energy storage in the cement industry. Final report, September 1977--March 1978

Description: In the manufacture of cement, literally trillions of Btu's are rejected to the environment each year. The purpose of this feasibility study program was to determine whether thermal energy storage could be used to conserve or allow alternative uses of this rejected energy. This study identifies and quantifies the sources of rejected energy in the cement manufacturing process, establishes use of this energy, investigates various storage system concepts, and selects energy conservation systems for further study. Thermal performance and economic analyses are performed on candidate storage systems for four typical cement plants representing various methods of manufacturing cement. Through the use of thermal energy storage in conjunction with waste heat electric power generation units, an estimated 2.4 x 10/sup 13/ Btu/year, or an equivalent of 4.0 x 10/sup 6/ barrels of oil per year, can be conserved. Attractive rates of return on investment of the proposed systems are an incentive for further development.

Array automated assembly. Phase 2: quarterly report for the quarter ending September 30, 1978

Description: Problems with excessive junction shunting previously reported were found to be associated with a malfunction discovered in one of the printers. Aluminum contamination of the front surface and junction edge were also identified as sources of shunting, as was damage to the tetrahedral peaks during handling of diffused wafers. Additional compositional variations of titania precipitated and baria--magnesia borosilicate glasses were prepared to improve fusion and maturation characteristics. An intensive effort was made to integrate the diffusion mask process into the process sequence. This attempt has been unsuccessful. All cells fabricated have had very low output attributable primarily to low shunt resistance. Alcoa 1401 and AMPAL (Atomized Metal Powder, Inc.) aluminum powders were tested as the base for making screen printing pastes for back surface P+ contacts. Time--temperature firing matrix experiments showed that optimum conditions were different for the two different pastes: 850/sup 0/C and 20 seconds for the paste based on Alcoa 1401 powder and 825/sup 0/C for 30 seconds for the paste based on the AMPAL powder. Additional peel strength data on protective coating materials were gathered. The effect of exposure to a swelling solvent on coating layers was added as a test of adhesive bonding to the substrate and the effectiveness of primer coupling agents. The preliminary tests indicate ability to discriminate between different primers used with RTV-type silicon coatings.

Automated Array Assembly, Phase II. Quarterly report No. 4

Description: The purpose of the overall program is to establish technological readiness and provide verification for the elements of a manufacturing sequence which would ultimately be suitable for the large-scale production of silicon solar-array modules at a selling price of less than $500/kW. A program and process plan for accomplishing this objective was developed and put into operation during the first quarter. The processing sequence is described. Three junction-formation processes are under consideration; since our cost analysis shows that they do not differ greatly in cost, each should be considered for technical merits and possible future cost reduction. The progress made in the various process steps of the plan is described, and conclusions are presented. (WHK)

Automatic sample changers maintenance manual

Description: This manual describes and provides trouble-shooting aids for the Automatic Sample Changer electronics on the automatic beta counting system, developed by the Los Alamos Scientific Laboratory Group CNC-11. The output of a gas detector is shaped by a preamplifier, then is coupled to an amplifier. Amplifier output is discriminated and is the input to a scaler. An identification number is associated with each sample. At a predetermined count length, the identification number, scaler data plus other information is punched out on a data card. The next sample to be counted is automatically selected. The beta counter uses the same electronics as the prior count did, the only difference being the sample identification number and sample itself. This manual is intended as a step-by-step aid in trouble-shooting the electronics associated with positioning the sample, counting the sample, and getting the needed data punched on an 80-column data card.
