Impacts of the national energy programme on solar economics

Description: The National Energy Plan (NEP) sets as a goal the use of solar energy in two and a half million homes in 1985. A key provision of the NEP (as well as congressional alternatives) provides for the subsidization of solar equipment. The extent to which these subsidies (income tax credits) might offset the impact of continued energy-price control is examined. Regional prices and availability of conventional energy sources (oil, gas, and electricity) were compiled to obtain a current and consistent s… more

Studies of evaporative and conventional cooling of an energy conserving California house

Description: For cooling a Sacramento, California home, (1) higher thermostat settings, (2) insulation (3) ''solar control'' window shades, and (4) the use of an evaporative cooler in the place of a vapor compression cycle air conditioner are studied. A computer program TWOZONE is used to evaluate the effect on energy consumption and peak power. It is calculated that the peak cooling load can be reduced by a factor of 5 or more and the total energy by a factor of 20 or more.

Low-cost site-assembled solar collector designs for use with heat pumps

Description: Four low cost solar collector designs have been produced for use in solar assisted heat pump systems. Three principles guided the design: the use of air as the heat transfer medium, the use of on-site easy-to-install construction rather than modularized prefabricated construction, and the collection of solar energy at reduced temperatures.

Analysis of residential, industrial and commercial sector responses to potential electricity supply constraints in the 1990s

Description: There is considerable debate over the ability of electric generation capacity to meet the growing needs of the US economy in the 1990s. This study provides new perspective on that debate and examines the possibility of power outages resulting from electricity supply constraints. Previous studies have focused on electricity supply growth, demand growth, and on the linkages between electricity and economic growth. This study assumes the occurrence of electricity supply shortfalls in the 1990s and… more

Effect of reduced boiler water temperature on cycle efficiency

Description: Tests were performed on a ''typical'' residential hot water boiler to evaluate the energy saving potential of reduced boiler water temperature. A significant reduction of annual fuel consumption was determined based on detailed efficiency measurements combined with the BNL Seasonal Performance Evaluation Computational Program. The energy saving has been attributed to reduced off-cycle heat losses resulting from the lower boiler operating temperature.

Preparation of a computer-compatible data base on an operating total energy system. Final report. [Indian Creek Village, Overland Park, Johnson Co. , Kansas]

Description: This report documents the development of a computerized data base on the long-term performance of the Indian Creek Total Energy System, and it is intended to be a user's manual for the data base and the accompanying energy-balance computer program. The data base may be used as a standard of comparison for the performance predicted by energy-system-simulation software. The TES became operational in 1972 to meet the projected electrical, space conditioning, and domestic hot water needs for t… more

Socioeconomic impact of photovoltaic power at Schuchulik, Arizona. Final report

Description: Schuchuli, a small remote village on the Papago Indian Reservation in southwest Arizona, is 27 kilometers (17 miles) from the nearest available utility power. In some respects, Schuchuli resembles many of the rural villages in other parts of the world. For example, it's relatively small in size (about 60 residents), composed of a number of extended family groupings, and remotely situated relative to major population centers (190 km, or 120 miles, from Tucson). Its lack of conventional power is … more

Open-cycle absorption cooling using packed-bed absorbent reconcentration

Description: The technical feasibility of a lithium chloride open-cycle absorption air conditioner using solar-heated air for reconcentration of the absorbent solution is examined. In contrast to a successfully operating Soviet design (in which absorbent reconcentration is accomplished by trickling the solution across a sloping black roof exposed to the sun), this study involves a packed-bed concentrator. Solar-heated air reconcentrates the solution by vaporizing water (the refrigerant) from the solution in… more

Adaptive control for energy conservation

Description: The objective of this project is to investigate the use of adaptive control concepts in buildings with solar-assisted heating, ventilating, and air-conditioning (HVAC) systems to maintain occupant comfort conditions while minimizing auxiliary energy use. Accomplishing this objective requires an energy management system capable of making sound tradeoffs. Optimal control theory is used along with a system identification technique to provide an adaptable stratgy. The resulting overall approach is … more

Unitary solar heating/cooling system package development. Progress report, June 1, 1977--January 31, 1978

Description: During this period, a 3 ton residential system hardware package has been developed and is operating in an Arkla owned solar house in Evansville. The Arkla tower-cooled WF36 chiller has been substituted for the evaporatively cooled chiller under development in the package. The residential software and manufacturing programs are underway. Only preliminary thinking has been done on the commercial 25 ton program which will soon be getting major attention.

Economy of a retrofit solar system

Description: A privately financed solar-augmented hot water system has been demonstrated to pay off in less than 10 years if a loan is obtained at 10.5% interest. Calculations were made on the assumption that electricity costs 5 cents per kWh and water consumption averages 30 gallons per day (using current technology on an existing dwelling in Tennessee).
