  Modeling Cogeneration System in Shallow Geothermal Installations

  By Leticia Bottazzi, Carlos Armenta-Deu

  Abstract: This paper presents a theoretical modeling of a cogeneration system using multiple heat exchangers and thermoelectric generator. The modeled system, designed for shallow geothermal energy, is a closed piping unit containing water as heat transfer fluid that circulates through a closed loop releasing thermal energy at the surface for heating and sanitary hot water. In addition, a Peltier cells array is attached to the piping system to generate electricity, thus …

  Thermal and Thermoelectric Generation Using Geothermal Energy Extraction Through Cogeneration System

  By Carlos Armenta-Deu, Leticia Bottazzi

  Abstract: The manuscript has focused on the evaluation of the improvement of energy efficiency in using geothermal energy for heat and electricity generation through additional thermoelectric production to conventional heat transfer processes. The proposed system uses Peltier rings made up of a serial and parallel Peltier cells grouping, as part of the upward and downward ducts that connect the geothermal heat exchanger and the surface heating system. The new system can …
