Abstract
Termoelektrične toplotne črpalke, ki delujejo na osnovi termoelektričnega pojava, predstavljajo eno izmed alternativ parno-kompresijski tehnologiji. Na trgu že najdemo termoelektrične hladilne naprave, termoelektrične toplotne črpalke pa so šele v fazi razvoja. V sklopu diplomske naloge smo zasnovali, izdelali in eksperimentalno ovrednotili osnovno komponento termoelektrične toplotne črpalke. Diplomsko delo obravnava zasnovo in izdelavo kompaktnega prenosnika toplote iz silikonskega elastomera z vgrajenim termoelektričnim modulom. V delu so opisane osnove prenosa toplote in delovanje termoelektričnega modula. Podrobno so opisane vse faze in postopki izdelave prenosnika toplote. Prikazana je merilna proga in postopki meritev z obravnavo merilnih negotovosti. Delovanje prenosnika je preverjeno v treh različnih režimih delovanja, pri čemer je kot medij za prenos toplote uporabljena voda. Za vsak režim delovanja so prikazane temperaturne razlike vode med vstopom in izstopom iz prenosnika na hladni in topli strani termoelektričnega modula. Na podlagi izmerjenih temperaturnih razlik so izračunana in prikazana grelna in hladilna števila COP.

Title:Heat exchanger with integrated thermoelectric module
Abstract:
Thermoelectric heat pumps, which operate based on the thermoelectric effect, represent an alternative to vapor-compression technology. Thermoelectric cooling devices are already available on the market, but thermoelectric heat pumps are still in the developmental stage. In this thesis, we designed, fabricated, and experimentally evaluated a basic component of a thermoelectric heat pump. The thesis discusses the design and fabrication of a compact heat exchanger made from silicone elastomer with an integrated thermoelectric module. The fundamentals of heat transfer and the operation of the thermoelectric module are described. All phases and procedures involved in the fabrication of the heat exchanger are detailed. The measurement setup and procedures, including the consideration of measurement uncertainties, are presented. The performance of the heat exchanger was tested in three different operating modes, with water used as the heat transfer medium. For each operating mode, the temperature differences of the water between the inlet and outlet of the heat exchanger on the hot and cold sides of the thermoelectric module are shown. Based on the measured temperature differences, the heating and cooling COP values were calculated and presented.

Keywords:heat exchanger, heat transfer, thermoelectric effect, heat pump, energy efficiency
