Performance study of a thermal-envelope house: Phase II. Cooling performance. Final report

Description: The thermal envelope house is shown to perform much better than conventional houses without mechanical refrigeration and better than one would expect from most passively cooled houses in the hot-humid climate of Georgia. Peak temperatures inside the house were 8 to 15/sup 0/F below peak ambient temperatures. Peak inside temperature measured during the test period was 80/sup 0/F with an outside ambient peak of 93/sup 0/F. Air flow rates within the envelope were less than 1 ft/sec even when the a… more

Large climate-moderating envelopes for enclosed structures: a preliminary evaluation of energy conservation potential

Description: An investigation was made of the basic impacts of putting a large secondary enclosure around a number of functions and thereby creating a Large Climate Moderating Envelope (LCME). This study is a preliminary estimate of the energy conservation benefits of an LCME. A hypothetical LMCE design was chosen and a coupled fluid dynamic and energy transport analysis was performed to estimate the energy conservation potential of this design. The heat transfer models included insolation, outside air temp… more

Energy conservation in electrostatic fabric filtration of industrial dust

Description: Conservation in energy consumption in industrial fabric filtration systems has become very important due to the substantial increase in energy costs. Recently, an external electric field was utilized in the industrial dust control by fabric filters with very promising initial results. A substantial decrease in the pressure drop and an increase in collection efficiency were observed. The detailed outcome of the experimental research program in electrostatic fabric filtration was presented. The r… more

Residential Consumer's Handbook for Wood-Fired Appliances

Description: This manual describes the various types of wood burning appliances and accessories on the market. The characteristics of the various types of units are given to assess the best unit for a given application. Tips on selecting a unit are given. The most important overall considerations are shown to be the size (heat output) and safety features of the unit. Performance parameters, particularly heat output and efficiency, are defined. Test values for these parameters for several appliances of each … more

Energy conservation in grain (corn) drying with combination high-temperature, low-temperature methods. Final report, July 1, 1978-September 30, 1980

Description: Field drying experiments were carried out during the 1975 through 1978 harvest seasons at the University of Minnesota Rosemount Experiment Station. Several combination drying experiments were conducted each season along with a control (conventional drying) experiment. Based on the results of the field experiments, comparisons of energy requirements for combination and conventional drying were made. Performance of the low-temperature, in-storage phase of combination drying was evaluated using co… more

Test results and analysis of a convective loop solar air collector

Description: The test results and analysis methods employed in studying the general design parameters of an air convective loop solar collector are presented. The purpose of the test program is to validate a simulation model that can also be extended to other collector arrangements and to a variety of weather patterns. Details of the collector configurations, typical test results, simulation model, and comparison between test and analysis results are discussed. The good agreement between test and analysis s… more

Atmospheric studies in complex terrain: a planning guide for future studies

Description: The objective of this study is to assist the US Department of Energy in Conducting its atmospheric studies in complex terrain (ASCOT0 by defining various complex terrain research systems and relating these options to specific landforms sites. This includes: (1) reviewing past meteorological and diffusion research on complex terrain; (2) relating specific terrain-induced airflow phenomena to specific landforms and time and space scales; (3) evaluating the technical difficulty of modeling and mea… more

Dry/wet performance of a plate-fin air-cooled heat exchanger with continuous corrugated fins

Description: The performance and operating characteristics of a plate-fin heat exchanger in dry/wet or deluge operations was experimentally determined. Development of the deluge heat/mass transfer model continued. The experiments were conducted in a specially-designed wind tunnel at the PNL. Air that was first heated and humidified to specified conditions was circulated at a controlled rate through a 2 ft x 6 ft heat exchanger module. The heat exchanger used in the tests was a wavy surface, plate fin on tub… more

Impact of energy-conserving retrofits on indoor air quality in residental housing

Description: The impact of energy-conservation retrofits on the indoor air quality of residential buildings is being assessed through a field-monitoring project in which air leakage, air exchange rates, and indoor air pollutants are measured before and after retrofit measures are implemented. A mobile laboratory was used to make detailed on-site measurements of air exchange rate and concentrations of radon, formaldehyde, total aldehydes, particulates, carbon dioxide, carbon monoxide, nitrogen dioxide, nitri… more

Thermal storage wall model development in the DOE-2 computer program

Description: The DOE-2 building energy analysis computer program is being modified by the Los Alamos National Laboratory to include thermal storage wall modeling capabilities. This paper discusses model development and validation for vented and unvented thermal storage walls and water walls in DOE-2. The unvented wall model was validated by comparison with test-cell heating loads for both a selective surface and a night-insulated wall. The two commonly used vented wall models, the Akbari and Borgers correla… more

ASCOT FY-1981 progress report

Description: Since the DOE Atmospheric Studies in Complex Terrain (ASCOT) Program was initiated in 1978, the major emphasis of the program has been on the study of nocturnal drainage winds using The Geysers Known Geothermal Resource Area of northern California as the study site. Studies during this year were related to reducing and analyzing the data taken during a major field study in September 1980, model development and testing, and conducting the last series of field experiments in this area to determin… more
