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.
