Compression Refrigeration from a Solar-Powered Organic Rankine-Cycle
"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."

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.
