Stratified Thermal Storage in Residential Solar Energy Applications

Description: The benefits of thermal stratification in sensible heat storage were investigated for several residential solar applications. The operation of space heating, air conditioning and water heating systems with water storage was simulated on a computer. The performance of comparable systems with mixed and stratified storage was determined in terms of the fraction of the total load supplied by solar energy. The effects of design parameters such as collector efficiency, storage volume, tank geometry, … more

Solar Evacuated Tube Collector: Absorption Chiller Systems Simulation

Description: A residential air conditioning system incorporating an Arkla Solaire absorption chiller and Corning Glass Works evacuated tube collectors is simulated and the design parameters studied. Mathematical models of the evacuated tube collector and Arkla absorption chiller based on experimental results of the components have been created and incorporated into a complete system simulation.

Performance of Residential Solar Heating and Cooling System With Flat-Plate and Evacuated Tubular Collectors: Csu Solar House I

Description: Measurements in Solar House I at Colorado State University have provided comparison data on space heating, water heating, and cooling by systems in which flat-plate collectors and evacuated tube collectors were used. Data were procured on 47 days during operation of the flat-plate collector and on 112 days when the house was heated or cooled by the evacuated tube collector system. It was concluded that the system comprising an evacuated tubular collector, lithium bromide absorption water chille… more

Performance Comparison Between Air and Liquid Residential Solar Heating Systems

Description: Comparisons of system performance for the flat plate liquid-heating system in CSU Solar House I, the evacuated-tube collector system in Solar House I, and the flat plate air-heating system in CSU Solar House II are described for selected months of the 1976 and 1977 heating seasons. Only space and domestic water heating data are compared. The flat plate air- and liquid-heating collectors operating with complete heating systems have nearly equal efficiencies when based upon solar flux while the c… more

Evaluation of High Performance Evacuated Tubular Collectors in a Residential Heating and Cooling System: Colorado State University Solar House I. Report for October 1, 1976--September 30, 1977

Description: CSU Solar House I is configured with a prototype Corning evacuated tubular collector and a new Arkla lithium bromide water chiller designed for solar operation. Data have been collected for this configuration since January 1977. Prior to that time and since mid-1974, Solar House I has operated with a flat-plate collector and a previous Arkla LiBr air conditioner modified to operate in the lower solar temperature ranges. Project objectives were to develop an operating and control system for the … more

Volumetric properties of vapor saturated aqueous calcium chloride solutions from 0/sup 0/ to 300/sup 0/C based on a regression of the available literature data

Description: An internally, consistent set of density values is supplied for vapor-saturated, aqueous calcium chloride solutions from 0/sup 0/ to 300/sup 0/C based on currently available experimental data. The tabulated density data were obtained from a computer regression of the P-V-T-X data from 37 references. (MHR)

Reconnaissance for mercury over geothermal areas of the Imperial Valley, California. [Analysis of samples of soil gas and gas from drill holes]

Description: Nine samples of soil gas and gas from drill holes were collected over and near two geothermal anomalies in the Imperial Valley, California, to measure the possible presence of mercury. With the instrumentation used, the smallest quantity of mercury that could be detected was 2 nanograms. No mercury was detected in any sample.

Remote sensing in a water-resources study of Yellowstone National Park, Wyoming, Montana, and Idaho

Description: This report describes the usefulness of remote-sensing data in a water-resources study of Yellowstone National Park by delineating warm and cool ground-water areas. Remote-sensing data from aircraft missions in August 1966, September 1967, August 1969, and May 1970 were compared with reconnaissance, ground-temperature surveys, and test-hole data. Thermal-water discharge areas can be determined from infrared imagery and photography from the aircraft missions. Contrasts on infrared imagery caused… more

Volumetric properties of aqueous sodium chloride solutions from 0/sup 0/ to 500/sup 0/C at pressures up to 2000 bars based on a regression of the available literature data

Description: A compilation of density values for aqueous sodium chloride solutions from 0 to 500/sup 0/C at pressures up to 2000 bars based on currently available experimental data is presented. These data are required to establish optimum operating temperatures, pressures, and flow rates for the production of geothermal brine fields, to minimize scaling and corrosion, and to design turbines for production of electricity.

Magnetotelluric soundings in the Darrough Hot Springs area, Nevada

Description: Two magnetotelluric soundings (MTS) were made in the Darrough Hot Springs area, one at the hot springs (38/sup 0/ 49' 29'' latitude, 117/sup 0/ 10' 55'' longitude) and the other four miles east (38/sup 0/ 49' 20'' latitude, 117/sup 0/ 06' 30'' longitude) of the hot springs. The Cagniard resistivities are tabulated along with the audio-magnetotelluric data for the hot springs and the one-dimensional model apparent resistivities derived from the data. The MTS data (.01 to .3 Hz) is strongly aniso… more

Sampling procedures and catalogue of samples for eight boreholes at Clear Lake, Lake County, California. [14 to 113 meters deep]

Description: Clear Lake, California, is situated in an area which has been subject to crustal movement, earthquake-generated ground shaking, volcanic eruptions, and climatic fluctuations during late Quaternary time. The U. S. Geological Survey, in cooperation with Lake County, has undertaken a study of the seismic, volcanic, and environmental history recorded in the late Quaternary sediments beneath the floor of the lake (Sims, 1974). This study is based on continuous core samples measuring 12 cm or 15 cm i… more

Temperature gradients in Harney County, Oregon

Description: As part of a brief reconnaissance of southeastern Oregon, temperatures were measured in five wells in the Harney Basin during May of 1972. The results are presented together with a summary of temperature gradients previously published by Bowen (1972) and one well measured by C. E. Van Ostrand. The location of the wells and the average temperature gradient in /sup 0/C/km and the temperature profiles measured by the U.S. Geological Survey are presented graphically. The wells vary in depth up to 4… more
