| Description/Abstract: | The absorption cycle is a process by which refrigeration
effect is produced through the use of two fluids and
some quantity of heat input, rather than electrical input as in
the more familiar vapor compression cycle. Both vapor
compression and absorption refrigeration cycles accomplish
the removal of heat through the evaporation of a refrigerant
at a low pressure and the rejection of heat through the
condensation of the refrigerant at a higher pressure. The
method of creating the pressure difference and circulating
the refrigerant is the primary difference between the two
cycles. The vapor compression cycle employs a mechanical
compressor to create the pressure differences necessary to
circulate the refrigerant. In the absorption system, a
secondary fluid or absorbent is used to circulate the
refrigerant. Because the temperature requirements for the
cycle fall into the low-to-moderate temperature range, and
there is significant potential for electrical energy savings,
absorption would seem to be a good prospect for geothermal
application.
Absorption machines are commercially available today
in two basic configurations. For applications above 32oF
(primarily air conditioning), the cycle uses lithium bromide
as the absorbent and water as the refrigerant. For applications
below 32oF, an ammonia/water cycle is employed with
ammonia as the refrigerant and water as the absorbent. |
