Sargent, S.L. and W.P. Teagan.

Compression Refrigeration from a Solar-Powered Organic Rankine-Cycle
Engine. New York, Anerican Society of Mechanical Engineers, 1973.

"Solar-powered air conditioning is potentially one of the most advantageous solar applications, since its large scale use would reduce peak electrical demand as well as total energy consumption. Virtually all solar refrigeration systems have used an absorption cycle, but recent advances in the technology of Rankine-cycle engines, using organic working fluids such as Freon, put solarpowered compression refrigeration within the realm of technical feasibility."

Swartman, R.K. and A.J. Newton.

Survey of Solar-Powered Refrigeration. New York, American Society of
Mechanical Engineers, 1973.

"A survey is carried out on the application of solar energy to
refrigeration. The literature is reviewed in chronological
order showing the progress since the first attempt in 1936.
Two systems are considered: The vapor-compression and the
absorption systems. Various significant developments are
reviewed and their potential critically assessed."

Swet, C. J.

The Prototype Solar Kitchen. New York, American Society for Mechanical
Eneineers, 1973.

"A prototype solar kitchen is described that can provide high grade
thermal energy for a variety of household uses. The heat is avail.
able indoors, in the evening, during periods of intermittent cloudi.
ness, and in high winds, without manual positioning to follow the
sun. The prototype unit is designed with the cooking and baking
needs of a small family in mind, but the basic design is scalable
to much larger heat delivery rates and adaptable to many other uses."

GLOSSARY

Absorption cooling. Refrigeration or air conditioning achieved by an

absorption-desorption process that can utilize solar heat to produce

a cooling effect. Absorptivity. The ratio of the incident radiant energy absorbed by a sur. •

face to the total radiant energy falling on the surface. Albedo. The ratio of the light reflected by a surface to the light falling

on it. Ambient temperature. Prevailing temperature outside a building. Anaerobic fermentation. Fermentation process caused by bacteria in the

absence of oxygen. Bio-conversion. Use of sunlight to grow plants with subsequent use of

the plants to provide energy. Brayton cycle. Power plant using a gas turbine to drive a compressor and

produce power. A gas is compressed, then heated, then expanded through a turbine, then cooled. The turbine produces more power

than is needed to drive the compressor. British Thermal Unit (BTU). A unit of energy which is equal to the amount

of heat required to raise the temperature of a pound of water one

degree Fahrenheit. Capital cost. The cost of construction, including design costs, land costs,

and other costs necessary to build a facility. Does not include operat

ing costs. Capture efficiency of plants. The ratio of the energy absorbed and con

verted into tissue by plants to the total solar energy falling on the plants. This energy, usually about 3% or less of the total incident

solar energy, can be released when the plants are burned. Collector efficiency. The ratio of the energy collected by a solar collector

to the radiant energy incident on the collector. Concentration ratio (concentration factor). Ratio of radiant energy inten

sity at the hot spot of a focusing collector to the intensity of unconcentrated direct sunshine at the collector site.
