1. GENERAL INFORMATION
1.1 PRINCIPLES OF OPERATION
n 1834 Jean Peltier discovered that by passing a current through two dissimilar conductors the
junction of those materials will either absorb or release heat depending on the direction of the
current flow. Thirteen years earlier Thomas Seebeck had discovered that current would flow
when you placed a temperature gradient across the junction of two dissimilar metals. These
two discoveries were the basis of thermoelectrics. With the advent of modern semiconductors
thermoelectric devices became practical for real world applications and are now found in
everything from consumer goods to spacecraft.
Your ISC Sales, Inc Thermoelectric Air Conditioner operates on this principle so there is no
compressor and no expensive, ozone depleting CFC’s. ISC’s air conditioners use Thermoelectric
“modules” sandwiched between high performance aluminum heat sinks, high CFM axial fans, and a
patented electronic design to “pump” the heat from the inside of your enclosure to the outside,
without exposing your delicate electronics to any outside air or contaminates. See Figure 1.1.
ISC uses only the highest quality components in our air conditioners and you can expect
years of trouble free cooling from these solid-state devices. Every unit we sell is backed by our
one year parts and labor warranty.
