This paper presents a method for calculating the electrical power generated by a thermoelectric heat exchanger. The thermoelectric heat exchanger transfers heat from a hot fluid to a cold fluid through a thermoelectric generator located in the heat-exchanger wall separating the two fluid streams. The method presented here is an extension of the NTU method used to calculate heat-exchanger heat-transfer effectiveness. The effectiveness of thermoelectric power generation is expressed as the ratio of the actual power generated to the power that would be generated if the entire heat-exchanger area were operating at the inlet fluid temperatures. This method collapses results for several heat-exchanger configurations and allows a concise presentation of the results. It is shown that the NTU method of calculating heat-exchanger heat-transfer effectiveness can be modified in a similar way.

Electrical Power Output

Solar pond is one source of renewable thermal energy. The solar pond collects and stores thermal energy at the lower zone of the solar pond. The temperature at the lower zone can reach up to 90 °C. The solar pond is capable storing thermal energy for a long period. The stored thermal energy can be converted into electricity by using thermoelectric generators. These thermoelectric generators can be operated using the cold and hot zones from a solar pond. In this paper, the experimental investigation of power generation from the solar pond using thermoelectric generator and simple heat exchanger is discussed. A maximum of 7.02 W of electrical power output was obtained from a simple heat exchanger with 40 thermoelectric modules.
