PERSONAL COOLING SYSTEM
|
|||
|
|
|
|||
|
|
When crop dusting is done in the late afternoon, the cockpit
|
|||
|
|
temperature may be as high as 125 degrees Fahrenheit. Most plane's
|
|||
|
|
cockpits are not air conditioned because of the expense.
|
|||
|
|
|
|||
|
|
Cockpit heat poses a major problem because elevated body
|
|||
|
|
temperature can cause fatigue, dehydration and even collapse,
|
|||
|
|
extremely dangerous possibilities to a pilot flying at times only
|
|||
|
|
two to four feet above the vegetation.
|
|||
|
|
|
|||
|
|
Available now from Life Support Systems, Inc. (LSSI), Mountain
|
|||
|
|
View, California is a lightweight vest and a companion helmet
|
|||
|
|
headliner, Cool Head, through which cooling liquid circulates to a
|
|||
|
|
portable cooling package. The package includes a heat exchanger that
|
|||
|
|
cools the working fluid circulated through vest and headliner, and a
|
|||
|
|
control display unit containing a pump, a liquid reservoir,
|
|||
|
|
temperature control and power unit. Cool Head can operate from its
|
|||
|
|
own rechargeable battery or from the airplane's, or other vehicles
|
|||
|
|
power system.
|
|||
|
|
|
|||
|
|
Cool Head technology originated in a 1968 NASA deelopment
|
|||
|
|
progr<67>m that produced a channeled cooling garment for space wear. In
|
|||
|
|
1971, NASA's Ames Research Center awarded a contract to Acurex
|
|||
|
|
Corporation for an extension of the technology involving development
|
|||
|
|
of a heat stress alleviating liquid-cooled headliner for helicopter
|
|||
|
|
pilots. In the mid-1970s, NASA and the Bureau of Mines jointly
|
|||
|
|
sponsored an Acurex program for development of a self-contained
|
|||
|
|
cooling system for mine rescue workers. In 1980, William Elkins,
|
|||
|
|
formerly with Acurex and long associated with cooling system
|
|||
|
|
research, formed LSSI to pursue commercial uses of the technology.
|
|||
|
|
|
|||
|
|
Cool Head personal cooling systems have been acquired by the
|
|||
|
|
Army and Air Force for use by personnel who must perform arduous
|
|||
|
|
work while wearing hot and bulky protective gear, such as garments
|
|||
|
|
to prevent contact with chemical/bacteriological warfare agents.
|
|||
|
|
Cool Heads have also been bought by the U.S. Navy for evaluation in
|
|||
|
|
helicopters and light aircraft, and by military units of foreign
|
|||
|
|
governments.
|
|||
|
|
|
|||
|
|
Among commercial applications are use by employees susceptible
|
|||
|
|
to on-the-job heat stress in such industries as primary metals
|
|||
|
|
reduction, deep mining, chemicals, paper and glass. Other
|
|||
|
|
commercial uses include pe sonal cooling for heavy equipment
|
|||
|
|
operators and workers wearing toxic waste clean-up suits. Cool Head
|
|||
|
|
is also being used by a number of auto racing drivers.
