| dc.description.abstract | In the past the possibility of thermoelectric refrigeration has been considered, but
all Attempts to produce a practical refrigerator have failed owing to lack of suitable
Thermocouple materials. In this paper it is proposed that semiconductors should be
used and the factors governing their selection are discussed. It is concluded that the
semiconductors should be chosen with high mean atomic weights and that they
should be prepared with thermoelectric powers lying between 200 and 300 μV°C.
The Inspect of ongoing progress in Science and Technology has created a variety
of systems that can be used in producing of refrigeration effect with the use of
thermo electric module and photovoltaic module for generation of energy which
we further use for cooling & heating effect. The Most important utilization of the
portable cooler is for the preservation of insulin in extreme conditions a thermo
electric module is used instead of compressor so that it become portable, as it is
based on the principle of palter effect is to create a heating side and a cooling side
and also to maintain effectiveness.
Thermoelectric cooler is a solid-state heat pump which uses the component are
available commercially. The thermoelectric refrigerator does not produce
chlorofluorocarbon (CFC). It is pollutant free contains no liquids or gases, portable,
compact, creates no vibration or noise because of the differences in the mechanics
of the system. It is a prototype and its semiconductor materials, by palter effect, to
provide instantaneous cooling or heating. It has the advantage of having no moving
parts and thus maintenance free | en_US |
