ABSTRAKModul termoelektrik sebagai sebuah peralatan yang dapat mengubah energi listrik
menjadi sebuah gradien temperatur atau sebaliknya dengan adanya gradien
(perbedaan) temperatur, dapat mengubah energi panas (kalor) menjadi energi
listrik. Sebagai sistem temoelektrik generator, elemen ini tidak berisik,
perawatannya mudah, dimensi relatif kecil, ringan dan ramah terhadap
lingkungan karena tidak menghasilkan polusi. Karena melimpahnya panas
buangan dari pabrik, rumah tangga, perangkat elektronik dan iradiasi matahari
yang ada, modul termoelektrik akan menjadi solusi teknologi alternatif yang
murah dan ramah lingkungan bila digunakan sebagai sebuah generator
(pembangkit daya) penghasil listrik dengan memanfaatkan panas buangan
tersebut.
Penelitian ini dilakukan dengan metode eksperimen. Eksperimen yang telah
dilakukan dengan menguji karakteristik modul termoelektrik pada 3 sumber kalor
yang berbeda, yaitu: dengan menggunakan sumber kalor fluida (air) panas,
sumber panas radiasi matahari dan sumber panas bohlam halogen.
Dari penelitian yang telah dilakukan diperoleh beberapa hasil antara lain;
Karakterisasi modul TE pada sumber fluida panas menunjukkan bahwa dengan
kenaikan temperatur fluida panas 5°C terjadi peningkatan beda tegangan berkisar
sebesar 100 mV dan daya maksimum rata-rata dicapai sekitar 15 mW; dengan
penggunaan heat pipe membangkitkan daya yang jauh lebih besar 4-5 kali pada
modul TE tunggal (1.04 mW) dari modul TE tunggal tanpa heat pipe (0.15
mW), dan pada modul TE ganda yang menggunakan heat pipe menjadi 4 kali
lebih besar (1.48mW) dari modul TE ganda yang tanpa heat pipe ( 0.37mW);
diperoleh sebuah persamaan penentuan koefisien Seebeck untuk modul terkoneksi
=
dimana adalah koefisien Seebeck hasil koneksi, adalah
koefisien Seebeck tunggal.
ABSTRAKThermoelectric module as a device that can convert electrical energy into a
temperature gradient or vice versa with the gradient temperature, can change the
heat energy into electricity. As a thermoelectric generator system, this element is
not noisy, easy maintenance, relatively small dimensions, light weight and
environmentally friendly because it does not produce pollution. Because of the
abundance of waste heat from factories, household, electronic devices and
existing solar irradiation, thermoelectric modules would be a cheap alternative
technology solutions and environmentally friendly when used as a generator
producing electricity by utilizing the waste heat .
This research was conducted with the experimental method. Experiments have
been done by testing the characteristics of thermoelectric modules in 3 different
heat sources, namely: using heat of hot water, heat of the solar radiation and heat
of halogen bulb .
From the research that has been done shows some results, among others;
Characterization of the TE module to the heat source fluid showed that different
temperature of the hot fluid about 5°C will increase voltage range of 100 mV and
a maximum average power is achieved of about 15 mW; by the use of heat pipe
evokes a far greater power 4-5 times in a single TE module on (1.04 mW) than
that a single TE module without heat pipes on (0.15 mW), and the double TE
modules using heat pipes 4 times greater (1.48mW) of double TE modules
without heat pipes (0.37mW); was obtained an equation for the Seebeck
coefficient determination module connected k = C1/C2 t where k is the
Seebeck coefficient results of the connection, the Seebeck coefficient t of single
TE modules., Thermoelectric module as a device that can convert electrical energy into a
